The U.S. Military's $1,000,000,000,000 Question: Is Stealth Worth It?


Is the added cost of buying and operating a stealth fighter worth it?
The answers will vary depending on who you ask—and it depends on if one believes stealth is a baseline requirement to survive over a future battlefield or not.
The U.S. Air Force has publicly embraced stealth as the end all and be all, while the U.S. Navy has taken a more skeptical approach. While Air Force officials publicly pronounce that the F-35 will be able fight alone and unafraid, the Navy has argued for balanced survivability using a combination of assets including electronic attack, stand-off weapons and, yes, some measure of stealth.
Part of the difference in the two services’ diverging positions can be explained by different political messaging strategies. Publicly, the Air Force doesn’t want to admit the utility of electronic attack or support platforms because they seem to believe that might erode support for the F-35. Meanwhile, the Navy has bills to pay other than for aviation and that service doesn’t see the performance differential between the F/A-18E/F and F-35C as being worth the massive cost plus up.
After a discussion with Air Force and Navy officials—it’s apparent that the truth lies somewhere in between. There is consensus that in the future as anti-access/area denial threats evolve, wide-band all-aspect stealth will probably be necessary. But that likely requires a large flying-wing aircraft like a strategic bomber. Moreover, support assets including electronic attack and cyber are going to be part of the mix. Against the Chinese or Russians, no one is going to be able to go it alone.
A dispute starts to emerge on the advantages of high-frequency stealth aircraft—jets like the F-22 and F-35 which are designed to operate primarily against the C, X and Ku band radars. Navy leaders are adamant that the service needs complementary capabilities that include stealth as part of a larger overall bag of tricks. Meanwhile, Air Force leaders will assert that the F-35 in particular will operate without the support of any external electronic warfare assets. However, the service’s own air warfare experts at Nellis AFB, Nev., freely admit that stealth works best when complemented with other capabilities like electronic attack—and those officers recognize the need for a platform like the EA-18G Growler. Detection via radar is decided by the signal to noise ratio—stealth reduces the signal while jamming increases the noise. That’s just basic physics—ideally, one works both sides of the problem to achieve the best results.
At the tactical level—as I recently discussed with a good friend who is an Air Force Weapons School grad with lots of stealth experience—a four-ship of F-35Cs supported by Growlers and E-2D Advanced Hawkeyes and other naval assets is likely to be more effective than a four-ship of Super Hornets operating with the same support assets. While the F-35C does not have good kinematic performance, it does (or will eventually) have stealth, excellent sensors and phenomenal electronic warfare capabilities. Indeed, combining the F-35C with the Super Hornet might work very well in a scenario where the Joint Strike Fighter is used as a spotter for the F/A-18E/Fs. Indeed, the Navy’s director of air warfare Rear Adm. Mike Manazir told me as such a couple of years ago when I was at the U.S. Naval Institute.
But the problem for the Navy is that the F-35C is expensive both to buy and sustain onboard a carrier. There are many in the Navy that simply don’t believe that any added performance benefits the F-35C brings to the table would be worth the massive additional cost. Moreover, there is a growing understanding in the naval community that the F-35C fundamentally does not have the range or payload needed to keep the carrier relevant in the anti-access/area denial environment of the Western Pacific. Indeed, there have been suggestions that the Navy truncate or cancel its portion of the Joint Strike Fighter buy. But only time will tell…

Full scale or miniature prototypes of the long range strike bomber may have already been built for testing


Prototypes of new US long range strike bombers may already have been built and tested after it was revealed that spending on the project has jumped to $1 billion in 2015.

The U.S. Air Force is moving forward with plans for a top-secret next generation bomber that could one day fly without a pilot.

Spending on the project has topped a billion dollars this year alone - and companies vying to win a contract to build the bombers are already said to have built either full-scale or miniature prototypes and tested them in wind tunnels.

Spending on the long range bomber was $200 million in 2012.
A billion dollars has been spent in 2015.
Spending could increase to $3 billion in 2018.

100 brand-new bombers will hopefully cost as $55 billion in total. They will replace 1960s-vintage B-52s and B-1s from the ’80s.

New Pentagon Equipment Is No Longer Pushing the Envelope


For the past six years, a newly cost-conscious Pentagon has aimed to buy arms that are less complex and use more existing or commercial technology. And it’s worked. The cost of major projects is dropping, says Frank Kendall, the defense undersecretary for acquisition. And he has the data to prove it.
But the bad news, Kendall says in a new 210-page report, is that Pentagon arms buyers have become so risk-adverse that America’s cutting-edge weapons aren’t quite so cutting-edge. And that’s allowing China and Russia to catch up.
“In my view, our new product pipeline is not as robust as it should be at a time when our technological superiority is being seriously challenged by potential adversaries,” Kendall said in his report, which analyzes the state of Pentagon’s massive, multibillion-dollar acquisition establishment.
He’s not alone. Last month at a military conference in London, the Dutch air force chief called out the U.S. Army’s effort to build future helicopters, saying it doesn’t push the envelope enough. Lt. Gen. Alexander Schnitger declared that the two primary designs now being evaluated are unambitious and could fall far short of what NATO needs to win a war in 2040.
Kendall has been sounding the alarm that the U.S. military’s technological superiority over its potential foes is narrowing, particularly when it comes to new Chinese equipment.
“In some areas we may not be pushing the state-of-the-art enough in terms of technical performance,” he wrote.
Historically, big Pentagon weapons programs have been susceptible to “requirements creep,” the accretion of program goals that have slowed development and sent costs skyward. The VH-71 effort to replace Marine One — the presidential helicopter — fell apart in large part because the requirements were still being changed even as aircraft were being built.
To fix this, Kendall and others have instituted changes — under the broad name of Better Buying Power — that locked down program requirements early on. But in a rapid-changing world, and with U.S. weapons-development timelines still measures in years, Kendall’s new report seems to question whether locking in requirements early is the best way to proceed.
Now he argues that not all cost growth is bad, particularly when it responds to a global threat.
“Simply delivering what was initially required on cost and schedule can lead to failure in achieving our evolving national security mission — the reason defense acquisition exists in the first place,” he writes.
On the flip side, Kendall says, many of the acquisition reforms put in place by him and his predecessor, current Defense Secretary Ashton Carter, are working. Defense firms are making more profit based on performance and companies are “doing a better job of meeting cost targets.”
An initiative called “should-cost,” appears “to be taking hold,” which is a “major cultural change,”  Kendall wrote. Should-cost “requires our managers to actively seek ways to save money and to set targets for doing so, not just to stay within their budgets,” he said.
Shay Assad is the director of defense pricing — the person who determines what projects should cost the Pentagon. He cited a “space-related procurement” in which the Pentagon saved $900 million in a single year. In another project, the Pentagon saved more than $2 billion over a five-year period.
“We’ve saved billions of dollars, I know we have,” Assad said.
In a certain helicopter deal, the Pentagon entered negotiations predicting that a multiyear contract might save 10 percent; instead, they squeezed 20 percent out, he said.
“What we’re trying to get the companies to focus on is accepting challenging, but doable cost,” Assad said in a July interview. “Those companies that are, they’re making more profit.”
Kendall’s report found that subcontractors to major firms are making a higher percentage of profit than the company’s they are supplying. “Since 2001, first-tier subcontractors earned higher margins than their associated prime contractors on the same program,” he wrote.
The report also fired shots at lawmakers — including Sen. John McCain, R-Ariz., chairman of the Senate Armed Services Committee — who have proposed to give more acquisition power to the uniformed service chiefs. After 2017, according to the proposed legislation, new major projects would be overseen by the military services, while the defense undersecretary for acquisition would thereafter control only joint projects or service-specific ones the defense secretary delegates.
McCain and supporters of his legislation argue the changes add accountability to acquisition projects. Kendall says the data in his report shows that Better Buying Power is working and that lawmakers shouldn’t just make change to make change.
“I encourage the stakeholders of defense acquisition to examine this report, prior reports, and other data-driven analyses to help guide ongoing discussions and policymaking,” he said. “While it is important to continue improving our policies and practices, change for change’s sake isn’t the answer. We should use experience supported by data-driven analysis to help ensure we don’t embrace policy reforms that carry unintended adverse consequences.”

Microwave absorbing circuit can enhance plane stealth


A team of Chinese researchers have made a breakthrough in stealth plane technology that could be so significant even local military sources say it should be kept out of the public realm.

The team released the technical and design details of an “invisibility circuit” they claim has the potential to help aircraft trick the best early warning systems in use today.

The researchers are affiliated with the Huazhong University of Science and Technology in Wuhan in central China’s Hubei province.

According to their paper, they have created a multi-layer electrical circuit that can “trap” microwaves at ultra-high frequencies, thus confusing radar systems and enabling aircraft to sneak past them















What is unique about the latest finding is that the material used to create the circuit would be almost impossibly thin. At under one centimeter, it is just a tenth the size of similar products developed by overseas competitors. This means it could be used to coat planes for the first time, pundits say.

Stealth planes including the F-22 and F-35 used by the US military are not quite as evasive as they sound, according to Huang, who said they can be spotted by advanced radar systems even from a considerable distance.

Such radars typically use microwaves at strengths of 2 gigahertz or lower to identify and track stealth aircraft. This is because the currently available coating materials can only absorb electromagnetic waves at high frequencies. Jiang’s team said the new circuits hit the military’s sweet spot as they can absorb waves ranging from 0.7Ghz to 1.9Ghz.

Many similar projects are kept under wraps because of their implications for national security and national defence. Some are supported by military funding, which prohibits their public disclosure.

The new circuit is not without problems.

First, it is unable to absorb microwaves generated at frequencies of 2Ghz or above, meaning that it could still be spotted by advanced radar systems, some of which can operate at over 40 Ghz.
As such, it could take years before it is used on an actual aircraft, Huang said.
It may initially be applied as an undercoat beneath other cutting-edge paints that are already used on stealth planes, he added.

Winning the Airwaves: Sustaining America's Advantage in the Electromagnetic Spectrum

The comfort of a post–Cold War advantage has left America lagging.
The electromagnetic spectrum (EMS) is one of the most critical domains in modern warfare. While militaries have long used it to communicate, keep track of friendly forces and find and target enemies, emerging technological advances now promise to dramatically change how they will use the EMS in the future. In the same way that smartphones and the Internet are redefining how the world shares, shops, learns and works, new sensors and networking technologies will enable militaries to gain significant new advantages over competitors that fail to keep pace.
Unfortunately, “failed to keep pace” is an appropriate description of the Pentagon’s investments in EMS warfare capabilities over the last generation. In the absence of a peer rival following the end of the Cold War, DoD failed to pursue a new generation of capabilities needed to maintain its EMS superiority. This pause provided China, Russia and other rivals with an opportunity to field systems that target vulnerabilities in sensor and communication networks the U.S. military has come to depend on. As a result, America’s once significant military advantage in the EMS is eroding, and may in fact no longer exist. This does not have to remain the case. DoD has the opportunity to develop new operational concepts and technologies that will allow it to “leap ahead” of its competitors and create enduring advantages in EMS warfare.
A Long-Term Competition:
The ways in which militaries conducted EMS warfare have changed significantly over the last hundred-plus years. We can think of these changes as a series of major phases, each of which placed a different emphasis on the use of active or passive EMS capabilities and countermeasures. Within each phase, incremental improvements to existing EMS capabilities allowed militaries to gain temporary advantages over their competitors. These advantages dissipated as the other side developed the next generation of countermeasures. More enduring advantages were the product of new operational concepts and capabilities that enabled militaries to transition to a new phase of the EMS warfare competition before their rivals.
For example, in the waning years of the Cold War, the U.S. military began this type of leap by embracing technologies that would reduce the detectability of U.S. forces in the EMS, such as stealth and low probability of interception/low probability of detection (LPI/LPD) sensors and communication systems. This transition promised to give U.S. forces a distinct advantage over Soviet forces that continued to rely on high-power sensors, communications systems and jammers. It was never completed, however, due to the dissolution of the Soviet Union. Following the end of the Cold War, DoD truncated a number of key programs intended to support this transition, including those building stealth B-2 bombers and F-22 fighters.
Today, the Pentagon has an opportunity to gain an enduring advantage over America’s enemies by finishing the transition to the next phase of the EMS warfare competition. A shorthand way of describing this new approach would be “low-to-no power” EMS warfare, where emissions from sensors, communication systems, jammers and major platforms that must operate in contested areas minimize their detectable emissions. This should be one focus of a “Third Offset” strategy that is intended to use new technologies to defeat the numerical and geographic advantages of potential enemies. If embraced by DoD’s leadership and funded by Congress, new operational concepts and capabilities for this next phase in EMS warfare would help the U.S. military to take back the airwaves and dominate this critical domain in which future wars may be won or lost.
New Operational Concepts:
The shift should begin with the creation of new operational concepts that inform DoD’s future capability requirements and investment priorities. Without operational concepts that describe new ways of fighting, the military services will not be able to update their doctrine, and the acquisition system cannot be prompted to incorporate new technologies. The Services are already pursuing some operational concepts for low-to-no power EMS warfare. The Navy, for instance, is developing tactics for E/A-18G Growler electronic attack aircraft to use passive capabilities, in order to geolocate threat emitters alone or in concert with other aircraft through the Navy Integrated Fire Control (NIFC) network.
Other concepts that would apply more broadly across the joint force and for a wider range of missions and scenarios in the low-to-no power EMS warfare regime include using passive and multi-static detection capabilities to find hostile forces while avoiding detection by their active and passive sensors; taking advantage of enhanced emissions control and low-power countermeasures to avoid detection while operating inside contested areas; and using a new generation of jammers, decoys and even directed energy weapons to support U.S. strikes and attack the enemy.
New Technologies:
Executing these new operational concepts will require the U.S. military to evolve and expand its portfolio of EMS capabilities. To operate effectively in a low-to-no power EMS warfare environment, DoD will need capabilities that are highly networked; able to “maneuver” across the EMS in order to remain undetected and target enemy networks; have the capacity to perform multiple EMS warfare functions such as communications, sensing, jamming, deception or decoying; and are small and cheap enough to be deployed on nearly every platform that must operate in contested areas. Most importantly, U.S. EMS warfare systems will need to be controlled by adaptable and intelligent processors that go beyond simply executing automated pre-planned responses and can develop techniques to sustain U.S. EMS operations while disrupting those of the enemy.
Some systems with these attributes are already in the U.S. military’s inventory or will be fielded in the next several years, such as the APG-77 and APG-81 radars on the F-22 and F-35, Air and Missile Defense Radar, Next Generation Jammer and SLQ-32 Surface Electronic Warfare Improvement Program (SEWIP) upgrade. Other potential capabilities are languishing in research and development due to a lack of new, validated requirements and other barriers that inhibit their transition into DoD’s acquisition system.
Overcoming Barriers:
Operating concepts and capabilities similar to those suggested above would help DoD to transition to the low-to-no power phase of EMS warfare. For this transition to occur, however, DoD will first need to address major conceptual, organizational and programmatic impediments to progress that derive from the lack of an institutional vision for how U.S. forces should fight in the EMS.
For instance, technologists, operators and policy makers often do not communicate effectively regarding the potential for emerging technologies to enable new approaches to warfare. While some in DoD are beginning to develop new concepts for the next phase in the EMS warfare competition, their efforts are hindered by the U.S. military’s continued emphasis on operating as it has in the past, rather than embracing new ways of operating and fighting in the EMS.
The lack of new operational concepts has inhibited DoD’s development of formal requirements that would “pull” new EMS warfare technologies into its acquisition process. Moreover, new systems that could support low-to-no power operations that are already fielded, such as active electronically scanned array (AESA) radars, are prized more for their ability to support old operational concepts rather than their potential to enable different approaches to EMS warfare.
The Pentagon could overcome these barriers with a concerted effort initiated and overseen by the new Electronic Warfare Executive Committee (EXCOM). The EXCOM should oversee the development and implementation of a new vision for how future U.S. forces will operate and fight in the EMS. This vision should guide the efforts of the Services and Defense Agencies to develop low-to-no power EMS warfighting operating concepts and requirements.
To ensure the services are able to implement these new approaches to EMS warfare, DoD should prioritize its research and development investments to further mature networking, agility, multifunctionality, miniaturization and adaptability technologies. And to enable these technologies to transition, the Services should greatly increase cooperation between multiple executive and management offices now responsible for developing and procuring new EMS warfare systems. This would help DoD as a whole to field more agile, multifunction capabilities essential to future EMS warfare operations.
American and allied military forces have gained significant advantages over their enemies in previous EMS warfare competitive regimes. A failure to develop new operational concepts and capabilities needed for this next phase of EMS warfare, however, could result in situations where the U.S. military will be at risk of losing the battle for the airwaves.

Electronic Warfare version of China J-16 twin seat fighter similar to USA EA-18 Growler


A possible new electronic warfare (EW) variant of the Shenyang Aircraft Corporation (SAC) J-16 twin-seat strike fighter made its first flight on 18 December, according to Chinese sources, potentially adding a significant offensive capability to the People's Liberation Army Air Force (PLAAF).

Images of the new variant have emerged on several Chinese military web pages, including a 21 December 2015 video report on the popular Ifeng web page. The most salient modifications are two new wingtip pods similar to the Northrop Grumman AN/ALQ-218 Tactical Jamming Receiver, leading to comparisons with the E/A-18G Growler electronic attack variant of Boeing's Super Hornet.

The Boeing EA-18G Growler is an American carrier-based electronic warfare aircraft, a specialized version of the two-seat F/A-18F Super Hornet.

This possible J-16 EW prototype appears to lack the usual fuselage-mounted gun and the infrared search and tracking system (IRST) also appears to be missing, but the J-16, which resembles the Russian Sukhoi Su-30, would have up to 10 wing and fuselage hardpoints for ordnance and active jamming pods.

An EW version of the J-16 equipped similarly to the E/A-18G would give PLAAF strike packages a far greater chance of reaching their targets and avoiding increasingly capable air defences.

Development of a J-16 EW variant could also lead to a similar carrier warfare version of the twin-seat J-15S.

While in early 2014 an Asian government source estimated that 100 J-16s would be in PLA service by 2020, the emergence of an EW version could increase that number.

Revealed: U.S. Navy's Plan to Defeat Russia's Deadly S-400

The U.S. Navy has decided to upgrade its Boeing EA-18G Growler fleet with the new high-speed Tactical Targeting Network Technology (TTNT) datalink and other new hardware following a successful demonstration of the new technologies at Fleet Experiment 2015 this summer. According to Boeing, all new Growlers currently in production will be fitted with the enhanced hardware while older jets will be retrofitted the new standard.
“This enhanced targeting capability provides our aircrews with a significant advantage, especially in an increasingly dense threat environment where longer-range targeting is critical to the fight,” said Capt. David Kindley, U.S. Navy F/A-18 and EA-18G program manager.
The enhanced hardware would allow multiple Growlers to coordinate their efforts against ever more capable enemy systems that proliferating around the world as part of the Naval Integrated Fire Control-Counter Air (NIFC-CA) battle network. According to Boeing, the upgrades include an advanced targeting processor, high-bandwidth datalink and a Windows-based tablet, which is integrated with the Growler’s mission system. The new upgrades are necessary to keep paces with an ever-changing threat environment.
“The complexity of global threat environments continues to evolve,” said Dan Gillian, Boeing F/A-18 and EA-18G programs vice president. “This long-range targeting technology is essential as we advance electronic attack capabilities for the conflicts of today and tomorrow.”
The Navy’s decision to upgrade the Growler fleet comes after the Fleet Experiment 2015 exercise validated the service’s concept to use multiple EA-18Gs to generate a “weapons quality track” against enemy emitters. Under the NIFC-CA construct, Rear Adm. Mike Manazir, the Navy’s director of air warfare, told me in December 2013 that the service would need a minimum of two airborne EA-18Gs linked via a high-speed datalink both to each other and to a third point—a Northrop Grumman E-2D Hawkeye—to perform a time distance of arrival analysis to precisely locate threat emitters.
With the three separate points, the Navy expects to be able to narrow down the location of multiple mobile threat emitters to a narrow enough “ellipse” as to generate a weapons quality track in real time. The tactic works best when there are three Growlers working in conjunction with each other—but an E-2D Advanced Hawkeye can substitute for one of the EA-18Gs. While the Hawkeye has an excellent electronic support measures suite, it has neither the capability of the EA-18G nor can it get as close to the threat.
The new technique is essential to the Navy’s plans to fight in a threat environment dominated by advanced integrated air defense systems that could include VHF radars better capable of tracking stealth aircraft and highly mobile double-digit surface-to-air missile (SAM) systems like the Russian–built S-400 Triumf (SA-21 Growler) or Chinese HQ-9.
Older techniques to suppress or destroy enemy air defenses relied on satellite imagery and long-range intelligence gathering aircraft to develop an order of battle for fixed enemy SAM sites. Those techniques are not effective against these newer, more mobile threats.

Russia is using french missile technology to develop hypersonic missiles and Russia could also deploy anti-hypersonic missile defense by 2019


Russia is using French missile technology to develop a new, ultra-high speed nuclear attack missile, the House Armed Services Committee disclosed this week.

According to the document, which is labeled “unclassified,” the graphic reveals how the French defense company MBDA Missile Systems and ONERA, the French national aerospace research center, are working with Raduga, a Russian missile manufacturer, and Rosoboronoexport, the Russian state arms company, to develop a hypersonic missile capable of reaching speeds of Mach 4 to Mach 8, or 3,069 miles per hour to 6,138 miles per hour.

Rogers said the hypersonic vehicle appears to be “a new nuclear weapon delivery system,” and questioned retired Air Force Gen. C. Robert Kehler, a former commander of the U.S. Strategic Command, about the weapon.

“In general terms, I would be concerned about technology transfer to any potential adversary,” Kehler said. “Whether Russia is an enemy is open for some conversation but I would be very concerned about technology transfer to any of the potential adversaries.”

The chart describes the flight test sequence of a Russian jet-powered hypersonic missile launched from a Tu-22 bomber and initially powered by a first stage derived from an “A84” missile.

After accelerating, the jet-powered missile flies for between 20 and 30 seconds at Mach 4 to Mach 8 over a distance of up to 25 miles before crashing. The missile send telemetry signals to an airborne receiver during the flight.


Thomas K. Scheber, a former Pentagon nuclear weapons policymaker and former Los Alamos National Laboratory official, said China, Russia, Pakistan, and India are developing advanced strike weapons.

“Numerous reports on Russian strategic force developments cite the potential value of deploying conventional warheads on ballistic missiles,” Scheber said, noting plans for conventional warheads on ballistic missiles.

“In November 2014 a Russian defense industry executive announced that Russia would have an air-launched hypersonic missile by 2020,” he added.

On China, Scheber noted that China conducted six test of a hypersonic glide vehicle designed to be launched from a long-range missile.

“The vehicle, dubbed DF-ZF in press reports, is described as capable of maneuvering to avoid defenses and gliding to its target at speeds up to ten times the speed of sound, i.e., hypersonic,” he said, noting that the “DF-ZF could carry either a nuclear warhead or perform non-nuclear strike missions.”

Russia Claiming Anti-hypersonic missile defense will be deployed by 2019

Russia's air defenses will have the ability to effectively repel hypersonic attacks by 2020, according to the Russian Ground Forces' Air Defense Force chief Alexander Leonov.

Russia's next generation air defense systems are set to enter service before the end of 2019.

This Is How China and Russia Plan to Crush America's Stealth Aircraft




Both China and Russia appear to be building unmanned aerial vehicles designed to negate America’s advantages in stealth aircraft.
Earlier this year, photos first emerged of a new High Altitude, Long Endurance (HALE) UAV termed the Divine Eagle that foreign observers believe is designed to detect and eliminate stealth enemy aircraft far from the Chinese mainland.
As Jeffrey Lin and P.W. Singer wrote back in May:
“[The Divine Eagle’s] long range anti-stealth capabilities can be used against both aircraft, like the B-2 bomber, and warships such as the DDG-1000 destroyer. Using the Divine Eagle as a picket, the Chinese air force could quickly intercept stealthy enemy aircraft, missiles and ships well before they come in range of the Mainland. Flying high, the Divine Eagle could also detect anti-ship missile trucks and air defenses on land, in preparation for offensive Chinese action.”
Russia appears to be designing a similar system, according to Flight Global.
While at the MAKS show in Moscow this week, Flight Global spoke with Vladimir Mikheev, the first deputy chief executive officer of the electronic systems producer KRET, about a new UAV being shown at the show, which KRET is a subcontractor on. During the interview, Mikheev said the new (thus far, unnamed UAV) is similar to China’s Divine Eagle in that it uses low frequency radars to detect low-observable stealth aircraft like the F-35, F-22 and B-2 bomber. Most stealth aircraft are created to evade high-frequency radar systems.
The Russian UAV goes a step further by integrating a sophisticated electronic warfare suite onto the aircraft. According to Flight Global, “Mikheev says KRET is providing a deeply-integrated electronic warfare system that not only provides a protective electromagnetic sphere around the aircraft to counter air-to-air missiles, but also cloaks it from radars.” Thus, if true, Russia’s new UAV would be able to detect America’s stealth aircraft without itself being detected. That could be a deadly combination.
Some in the U.S. military are already planning for a day in which stealth becomes mostly obsolete. As The National Interest previously noted, when discussing what America’s sixth generation fighter jet might look like back in February, Chief of Naval Operations Adm. Jonathan Greenert said that stealth may be overrated.
“You can only go so fast, and you know that stealth may be overrated.... Let's face it, if something moves fast through the air, disrupts molecules and puts out heat—I don't care how cool the engine can be, it's going to be detectable. You get my point."
It was not the first time that Greenert had questioned the long-term viability of stealth technology. In a 2012 paper, for instance, he said that better computing power would ultimately greatly undermine the value of stealth.
"Those developments do not herald the end of stealth, but they do show the limits of stealth design in getting platforms close enough to use short-range weapons," Greenert wrote at the time, according to the Navy Times.
"It is time to consider shifting our focus from platforms that rely solely on stealth to also include concepts for operating farther from adversaries using standoff weapons and unmanned systems — or employing electronic-warfare payloads to confuse or jam threat sensors rather than trying to hide from them."
Dave Majumdar has also observed on The National Interest that, “Russia and China are already working on new networked air defenses coupled with new radars operating in the UHF and VHF-bands that threaten to neutralize America’s massive investment in fifth-generation fighters. Fighter-sized stealth aircraft are only optimized to perform against high-frequency fire control band radars operating in the Ku, X, C and portions of the S-band.”
Not everyone completely agrees, however. For example, in response to Greenert’s comments about the stealth capabilities of America’s future 6th Generation fighter, Gen. Hawk Carlisle, the head of Air Combat Command, said that stealth will continue to be "hugely important."
“Stealth is wonderful, but you have to have more than stealth," Carlisle said, according to the Air Force Times. "You have to have fusion, you have to have different capabilities across the spectrum. It will be incredibly important. It won't be the only key attribute, and it isn't today."

US B-3 stealth bomber planned for 2025 will try to get through pickets of large anti-stealth radar drones


A new US bomber, likely called the B-3 (aka Long Range Strike Bomber - LRS-B), will replace all or most of the current fleets of B-52 and B-1 bombers, while complementing the B-2 bombers built by Northrop that have been flying since the 1990s. These will be stealthy, adaptable aircraft that will initially incorporate existing technologies. and as the name implies, be able to bomb targets from a distant range. The contract will be for 80 to 100 aircraft.

The U.S. Air Force misstated the 10-year cost for research, procurement and support of its new long-range bomber in annual reports to Congress. The correct costs estimates $41.7 billion for each of two periods out to 2026. The 10-year cost is the first installment in what could be a 30-year program.

Research-and-Development costs alone are estimated to be around $25 billion, although the bomber is supposed to mainly be built from existing technologies, saving the R and D expenditures associated with new hardware and software.

Specific details on the B-3 program are scant and remain classified. Only three things appear to be mostly locked in: a 2025 in-service-date, a $550-$810 million unit cost (excluding development), and an 80-to-100 aircraft fleet

One analyst called 100 new bombers a “wild fantasy” and expects per unit cost to rise to $3 billion.

The B-3 could also carry bunker-busting, rocket-boosted munitions, high-powered lasers for self-defense and datalinks, and consoles for controlling radar-evading drones.

With a combat radius between 2,000 and 2,500 nautical miles, the US Air Force's new stealth bomber, known as the Long-Range Strike Bomber or B-3, is capable of flying in Chinese airspace for one hour, reports China Aviation News.

The new bomber has been developed to reach targets located deep in the interior of Russia and China.


China and Russia are trying to develop large drones with multiple Active Electronically Scanned Array (AESA) radars, of the AMTI, SAR and GMTI varities to detect stealth planes. Airborne Moving Target Indicator (AMTI) radar types are used to track airborne targets, like enemy fighters and cruise missiles. Synthetic Aperture Radar (SAR) provides high resolution of slow moving ground vehicles and enemy bases.

High Altitude, Long Endurance (HALE) UAV like China's Divine Eagle could prove useful in both offensive and defensive operations. Its long range anti-stealth capabilities can be used against both aircraft, like the B-2 bomber, and warships such as the DDG-1000 destroyer. Using the Divine Eagle as a picket, the Chinese air force could quickly intercept stealthy enemy aircraft, missiles and ships well before they come in range of the Mainland.

Stealth planes are never completely invisible, as they will always generate a radar signature in the end according to Douglas Barrie, senior fellow for military aerospace at the International Institute for Strategic Studies in London. If you are seen five miles from your target, compared to be being spotted 100 miles away, then it will have done its job.

Anti-stealth countermeasures are now "proliferating". Whereas most radars operate between 2GHz and 40GHz, a low-band equivalent such as VHF radar operates between 1MHz and 2MHz and is able to pick out most stealth planes that are known to be flying today.

The Russians persevered with low-band radar due to their technological conservativism.

VHF can pick up "noise" such as clouds and rain, which was a reason why the West abandoned it – it does have basic physics on its side: its wavelength is the same magnitude as the prominent features on many stealth planes, so that its signal bounces back.

Russia and China (UK, USA, Australia, Israel, South Korea and basically any country with a modern air force) have VHF-Aesa (Actively scanned electronic array) radars.


Aesa (Actively scanned electronic array) radars like those supposedly on China's Divine Eagle drone are made up of a large number of solid state, chip-like modules that each emit an individual radio wave; these meet in front of the antenna to form a beam that can be easily aimed at a very specific target – and, combined with VHF, are an effective stealth-hunting tool.

Combining different radar and multiple large drones with radar to blanket an area

The final trick is "to combine together different radars into an integrated air-defence system and a central information-processing centre that can make life very difficult for any stealth fighter or bomber", Sutyagin says. And stealth planes are not always stealthy from every angle (it costs too much money). So if you have radar in front, at the sides and above – with a high-altitude drone such as the Divine Eagle – along with satellite tracking of any target, then it might well be a case of RIP stealth.

Popular Science has coverage of China's stealth hunting drones and radar



Divine Eagle has 7 radars include a X/UHF AMTI Active Electronically Scanned Array (AESA) radar on the front, two X/UHF AMTI/SAR/GMTI AESA radars on the twin booms, two X/UHF AMTI AESA radars on either side of the engine nozzles, and two more radars on the end of the booms. AMTI and GMTI radars are used for tracking air and surface targets, respectively, while SAR is used to provide detailed imagines of ground targets like bases and infrastructure.


Sina Defense. The JY-26 "Skywatch" AESA Radar, operates in the long wave band to detect stealth aircraft, which are often optimized against detection by shorter wavelenghts. The JY-26 is claimed to have a range of 500km and Chinese media claimed it detected F-22 Raptor fighters off the South Korean coast in mid 2014. The Divine Eagle is likely to have similar radar technology to detect stealth bomber and fighters at long range.

Planning Begins for USAF Next-Gen Air Dominance



WASHINGTON — The US Air Force is about to start a deep-dive process that will eventually decide what technologies and capabilities it will fund to ensure air dominance in the world of 2030.
And while that includes the potential for a sixth-generation fighter, top service officials continue to stress that the result of the process will likely be a family of systems approach.
Maj. Gen. Tim Ray, director of Global Power in the service's acquisition realm, and Maj. Gen. Paul Johnson, director for Operational Capability Requirements, told Defense News that the Air Force will shortly stand up a team to begin researching these decisions.
The Next-Generation Air Dominance program will be the first pilot program for the Air Force's new Capability Collaboration Team (CCT) structure, part of a broader strategic process unveiled by Gen. Mark Welsh, Air Force chief of staff, at last month's Air Force Association convention in Orlando.

The CCT comprises a number of operational, scientific and technical experts from an array of backgrounds, including the Defense Advanced Research Projects Agency (DARPA), the Air Force Research Labs and the major commands. The group will explore in depth various options that could matter in the future, before putting out a product with two components.
The first is a list of technologies the CCT has decided will be needed for air superiority in 2030. The second is a road map for how to achieve those technologies.
For example, the CCT could decide that directed energy weapons are a key part of the strategy. It will present to the chief and secretary a guide for what areas of directed energy need investment, how those investments should be prioritized, and perhaps most importantly, a timeline for when those investments would need to pay off in order to be fielded by 2030.
Johnson said the goal is to be able to guide limited research and development funds from being spread to many projects — with the hope that one works out — toward being focused on a small handful of technologies.
"It's not about a decision to start a program, to go do x, y and z," Johnson said. "It's not a decision to go build the next-generation fighter. It's a set of decisions about what more do we want to learn, how do we want to learn it, and how fast do we want to learn it? It's 'out of this set of technologies, we want to chase these four.' "
Timewise, the CCT will begin meeting in the next few weeks. It will spend the next three years researching technologies before presenting a final product in 2018.
The Pentagon is littered with well-intentioned studies into new technologies. What makes this different, Ray said, is the focus on finding actionable items and then creating guidelines to make them real.
"This isn't a slush fund," Ray said. "It's not just. 'hey I'm going to go solve cold fusion, give me a couple of years and I'll get back to you.' It's 'how do I get that power supply correct of that kind of pod to do directed energy,' or 'how do I get this signature from this range to that range?' "
For that to work, Ray said, industry must play a critical role. That fits with a promise from Welsh, who in Orlando pledged that industry would be brought in earlier in the technology development process.
"[Right now] you have to wait until we kind of make up our mind and give you a plan, so you can't energize your resources, your thinking, to help us get ahead of this curve," he said at the conference. "We're not talking to you about it. We must do that. You should be part of this transition planning. You should be part of the [process] in developmental planning."
At the same time, Ray warned that industry needs to be prepared for a shift away from the days of one prime controlling everything from development through production.
"We have a lot of known players and we want to hear what they have to say. The interesting part will be if we get out of the program business, how many more voices will we get that aren't the prime players?" Ray asked rhetorically. "Technology is moving way too fast for us to lock down a program and say it's all got to go through one guy."
That may lead to more focus on studying and prototyping technology without a guarantee of future production, Johnson said.
"When I bring industry in here, industry is understandably interested in what the program is going to look like, which is not my conversation at this point," Johnson said. "So I've got to make it workable so when I get ready to do some experimentation or prototyping, that industry is willing to participate in that, knowing that at the end of the day there may not be anything after that."
Rebecca Grant of IRIS Research said opening another avenue of communication with industry is a net positive for the service. And while she said the CCT brings "all the right ingredients" together, she said the service needs to stick with the concept to make it really work.
"The best technology development stories come out of this mix of people and insights," she said. "What we don't know is if you can get everyone together in a room and just [have] the big insights. Like exercise, you need do this on a regular basis and go for the small gains as well."
Mark Gunzinger, a former service official now with the Center for Strategic and Budgetary Assessments, called the CCT a "great idea" that could "help accelerate the transition of new, potentially game-changing technologies into the program of record." However, he also offered a word of caution.
"Beginning these efforts by 'researching new technologies' may take teams down the path of trying to figure out how emerging technologies could help airmen improve how they operate today," he said. "I think it's also important to challenge current operational concepts and think through how new technologies could enable airmen to operate very differently in the future."
Hints of the Future
Both generals stressed that the goal is to allow the CCT to be as open as possible as it explores future concepts.
"We can't be prescriptive. We do have to be open," Ray said. "We have to show them what's going on in the intel community with data management, with cyber, with space, so they can begin to look at the tools and what they mean and the implications of those things. It's a broader exposure."
However, the men did drop a few hints as to what technologies they foresee the CCT considering.
Johnson expressed confidence that the 2030 solution would not involve just the development of a heavily advanced fighter with all-onboard capability, noting "there is every likelihood it's going to be some sort of family of systems, and hopefully it will be a mix of old and new.
"I would have every expectation that it will probably be 'programs' — that's one man's opinion," he added. "Sensors, weapons, the whole collection of things."
That family could include a mix of modernized versions of legacy systems in use today, working hand-in-hand with new systems that will be online by 2030. The CCT will be on the lookout for what Johnson called "quick wins," things like experimental sensor upgrades that could be put onto current systems relatively quickly.
The CCT will also look at how to build in growth for potential future technologies, Ray said, noting "we certainly realize we need to build in more inherent adaptability in what we do."
That includes looking at how to build in excess power and create space for any new system, to make sure there is the ability to add newer technologies as they come along.
The generals casually mentioned directed energy and signature reduction as other technologies that will likely be looked at, which isn't news to anyone who has followed the talk about a potential next-generation fighter.
Grant highlighted directed energy as an area that could really gain from the CCT model.
"The time is right for demonstrating progress in directed energy," she said. "I think all future systems from here on out, we're going to have a discussion in directed energy on those systems. We'll be talking about it a lot more."
While the focus now is on the family of systems, there is confidence in industry that a major part of that will involve a sixth-generation fighter.

The Air Force isn't alone in looking at next-gen air dominance technologies. The Navy has said it is looking at a next-gen fighter to replace the F/A-18 and complement the F-35C, and Pentagon acquisition chief Frank Kendall has launched the Aerospace Innovation Initiative, a DARPA-led development program for X-planes to test technologies and concepts.
Johnson said he is in regular contact with his counterpart in the Navy, and Ray added that the lead Air Force representative to the initiative will also be part of the CCT.
That should create a cross-cutting of technologies between the three sides, including, perhaps, letting the CCT test some of the technologies on a prototype plane, then bring those results back into its research.
Industry, meanwhile, is gearing up for what could be a lucrative contract.
Northrop Grumman has already stood up a pair of teams, dedicated to the Navy and Air Force programs respectively, while Boeing has quietly released several mock-ups of future fighter concepts.
Orlando Carvalho, the head of Lockheed Martin's aerospace division, told Defense News that the company's SkunkWorks division is working on a design, but said that work is a natural outgrowth from the company's previous developments.
"When it comes to next-generation air dominance, that work for us is a continuum," he said. "We don't discretely stand up teams, disband teams around that — that's what we do at the SkunkWorks, and it's a continuum."
Carvalho said the Pentagon has "definitely" communicated with companies about what future threat scenarios, tactics and requirements may be.
Both Ray and Johnson are sympathetic to industry's desire to know what a next-generation fighter may look like, but insist they need this structure to prevent the proverbial cart from leading the horse.
"The automatic question [from industry] is when do we do the AOA [analysis of alternatives]? I don't want to hear about an AOA," Ray said. "I want to do some learning first. I want to know what the alternatives are before I begin to analyze those alternatives. Right now we don't even know what the alternatives are."

Russia’s fifth-generation Sukhoi T-50 PAK FA fighter jet is equipped with an advanced defense system that can neutralize an enemy plane’s stealth capability, a report said Friday, citing a unit of Russian state corporation Rostec. The planes, which will go into mass production in 2017, are claimed to be capable of outperforming the F-22 and fifth-generation F-35 fighters of the U.S. Air Force.
The T-50 PAK FA fighter jet will be built with composite materials, and come with advanced electronic systems and engines to ensure the plane can stay mostly undetected by radars and other optical and infrared technologies, Russia’s Sputnik News reported.
“The PAK FA is already to some degree a flying robot, where the aviator fulfils the function not only of pilot, but is actually one of the constituent parts of the flying apparatus,” Sputnik News quoted Vladimir Mikheyev, the deputy head of the Concern Radio-Electronic Technologies (KRET), a unit of Rostec, as saying.
KRET has created an advanced internal navigation system for the T-50 PAK FA jet, which autonomously processes navigation and flight information. The system can also determine position and motion parameters in situations when there is no satellite navigation, and make contact with GLONASS, Russia’s satellite-based navigation system, which works alongside the Global Positioning System.
The Russian air force will get 55 Sukhoi T-50 PAK FA jets by 2020 and the aircraft will replace the country’s Sukhoi Su-27 fourth-generation fighter jet. Russia is also expected to buy at least 50 Tupolev Tu-160 “Blackjack” heavy strategic bombers, which will be produced simultaneously with the country’s new bomber, called PAK DA.

Next Generation Air Dominance, previously called F/A-XX

Next Generation Air Dominance

From Wikipedia, the free encyclopedia
An early design concept of the Boeing F/A-XX
 
Next Generation Air Dominance, previously called F/A-XX, is a development and acquisition program for a future sixth-generation air superiority fighter to replace the United States Navy's F/A-18E/F Super Hornet beginning in 2025. A requirement was first identified in June 2008. [1]

Requirements

In April 2012, the Navy issued a formal request for information for the F/A-XX. It calls for an air superiority fighter with multi-role capabilities to replace the F/A-18E/F Super Hornet and EA-18G Growler aircraft in the 2030s, while complementing the F-35C Lightning II and UCLASS unmanned aircraft, that can operate in anti-access/area-denial environments. The aircraft must be capable of operating from Navy Nimitz-class and Gerald R. Ford-class aircraft carriers. Primary missions include air combat, ground attack, surface warfare, and close air support. Other missions can include air-to-air refueling, reconnaissance, surveillance, and target acquisition (RSTA), and electronic attack. There is consideration for manned, unmanned, and optionally manned platforms.[2]
The F/A-XX is being pursued as F/A-18 Super Hornets will reach the end of their 9,000 hours of service life by the early 2030s. Aside from the option of buying more F-35Cs, the F/A-XX is seeking to create a new aircraft to replace the Super Hornet's capability and mission set. An open architecture design is desired, so different sensors, payloads, and weapons can be plugged in for a specific mission, and be able to be moved around for multiple different missions on different days or different sorties. The resulting open architecture design is likely to take shape depending on which style of new propulsion system is presented by the aircraft industry. Unmanned, manned, and optionally manned systems are being considered. An Analysis of Alternatives (AOA) was expected to begin in 2014, with a fighter to be introduced around 2030. Just as the F-35C will replace aging F/A-18 Hornets and complement Super Hornets, the F/A-XX will replace aging Super Hornets in the 2030s and complement the F-35C.[3]
On 9 September 2014, the Navy announced that an AoA for the F/A-XX aircraft would begin in 2015. Meetings with industry will be held focusing on building new aircraft to meet the requirement, developing a family of systems (FoS) approach, and discussing mission systems, avionics, and new next-generation weapons systems. One approach could create a minimum cost F/A-XX that uses high cost, high performance weapons to defeat threats; according to the Navy's Naval Integrated Fire Control-Counter Air (NIFC-CA) battle network concept, an individual platform would not need to have a full suite of sensors and rely on off-board data-linked information from other platforms to provide targeting information and guide weapons launched from the platform. The F/A-XX platforms will be made to carry missiles, have power and cooling systems for directed energy weapons, and have sensors that can target small radar cross-section targets; cyber warfare platforms at a tactical level as part of a FoS are being explored. While the Navy is working with the U.S. Air Force on a next-generation tactical fighter, there is significant disagreement over the Air Force's claims that adaptive-cycle jet engine technology, where the ratios of bypass and compression airflow can be made variable to improve efficiency, can be scaled to benefit a carrier-based fighter.[4][5]
Although the F/A-XX platform will be a sixth-generation fighter aircraft, the Navy is reluctant to talk about a new aircraft because the project is still in the very early stages of development. A range of next-generation technologies may be explored including maximum sensor connectivity, super cruise ability, and electronically configured "smart skins." Maximum connectivity refers to massively increased communications and sensor technology, such as having the ability to connect with satellites, other aircraft, and anything providing real-time battlefield information. Engine technologies like scramjets would enable an aircraft to cruise at supersonic speeds without needing an afterburner. Smart skins would have sensors and electronics integrated into the fuselage of the aircraft itself to increase the technological ability of the sensors while reducing drag and increasing speed and maneuverability.[6]
Chief of Naval Operations Jonathan Greenert speculated in February 2015 that the F/A-XX would not rely on speed or stealth as much as previous generation jet fighters due to better signature detection and proliferating high-speed anti-aircraft weapons. Instead, the fighter would carry a new spectrum of weapons to overwhelm or suppress enemy air defenses. Greenert favors an optionally manned aircraft for a modular section that can either hold a pilot or more sensors. The payload of the F/A-XX will likely match or exceed the Super Hornet's payload.[7]

The Boeing F/A-XX concept design as of 2013.
 
In July 2009, Boeing unveiled a sixth-generation fighter concept the F/A-XX requirement. It was a two-seat, twin-engined tailless jet with a blended wing. Although it has a tandem cockpit, Boeing said it can be manned or unmanned depending on the mission. The fighter concept is in the 40,000 lb (18,000 kg) weight class. The Northrop Grumman X-47B that was chosen for the UCAS-D program has also been proposed for the F/A-XX effort.[1][8]
In a 31 May 2011 disclosure to Congress, the Department of Defense revealed that they were considering buying more F-35C fighters to replace 556 Super Hornets. The DOD plans to replace the older F/A-18C/D Hornets with 220 Lightning IIs. In March 2011, a Navy analysis of alternatives showed that they may buy more F-35C aircraft, develop a new platform, or do both for their NGAD fighter program.[9]
Boeing unveiled an updated F/A-XX sixth-generation fighter concept in April 2013. The concept is a tailless twin-engine stealth fighter available in manned and unmanned configurations. It has canards, which usually compromises the frontal radar cross-section, but the lack of a tail shows an emphasis on all-aspect stealth. It also has diverterless supersonic inlets similar to the F-35. The manned version seems to have restricted rearward visibility without the aid of a sensor.[10]
