Successful HAWC Test Doesn’t End DARPA’s Hypersonic Scramjet Efforts

Successful HAWC Test Doesn’t End DARPA’s Hypersonic Scramjet Efforts

DARPA is going to keep working on its Hypersonic Air-breathing Weapon Concept (HAWC) missile, even though the program for which it’s meant to be a technology pathfinder is already in source selection. A HAWC demonstrator flew successfully this month.

The new program is known as MoHAWC, but DARPA was not able to immediately explain the new acronym. An agency spokesperson referred to a line item in the fiscal 2023 budget request for continued Air Force/DARPA funding of $60 million for MoHAWC. The next phase of the program would “develop, integrate, and demonstrate technologies to increase effectiveness and producibility of an air-launched hypersonic cruise missile,” according to the budget request. HAWC is a joint effort of the Air Force and DARPA.

“These technologies include advancing hydrocarbon scramjet-powered propulsion operation, shrinking navigation components, upgrading aircraft integration algorithms, and improving manufacturing approaches,” according to the request. Continued flight tests would “expand the operational envelope.” DARPA would continue to collaborate with the Navy and Air Force on “efforts to meet future technology insertion dates for service programs of record.”

However, a Pentagon official said MoHAWC is “probably … moot” because the Air Force intends to make a choice between Boeing, Lockheed Martin, and Raytheon for the Hypersonic Attack Cruise Missile before the end of the fiscal year in September, and HAWC was intended to be a technology pathfinder for HACM.

“The main aspects of that [missile] are pretty much already locked down,” the official said. “It’s in source selection … so they’re not going to be changing anything at this stage.”

A former defense official noted that DARPA has continued working on its Tactical Boost Glide (TBG) program long after the Air Force decided to pursue the similar AGM-183A Air-launched Rapid Response Weapon (ARRW). DARPA is asking for $30 million to keep working on TBG and do a test shot in fiscal 2023.

“There could be some value in continuing to work on these projects after the programs they were meant to feed get going,” he said, “in the sense of, it gives you some diversity of approaches.” However, he acknowledged that the HAWC contractors—Lockheed Martin and Raytheon—are two of the three competitors for HACM, so little diversity would be achieved.

DARPA announced the “successful test flight” July 18. The vehicle that flew was one of two types of HAWC demonstrators DARPA is working on: the version made by Raytheon Technologies and Northrop Grumman, which built the vehicle and the scramjet engine, respectively. It was the second successful test flight for the Raytheon/Northrop vehicle, which first flew in September 2021. The other version, made by Lockheed Martin (vehicle) and Aerojet Rocketdyne (engine) made a successful test flight in mid-March.

The July test of the Raytheon version of HAWC “leveraged data collected during the 2021 flight,” DARPA said.

“After release from the aircraft, the first stage boosted the vehicle to the expected scramjet ignition envelope,” according to the agency. “From there, the missile’s Northrop Grumman scramjet engine fired up and propelled the cruiser to speeds greater than Mach 5 … for more than 300 nautical miles and reaching altitudes of greater than 60,000 feet.”

A DARPA spokesperson was not able to say how much of that 300 seconds was under power of the scramjet or how much was under power of the booster, which accelerates the vehicle to hypersonic speeds, considered to be Mach 5 or greater. As a rule of thumb, travel at Mach 5 equates to one mile per second, so the missile could have flown up to 300 seconds under scramjet power.

“The most recent test allowed exploration of more of the flight and scramjet engine operating envelopes,” DARPA’s HAWC program manager Andrew Knoedler said in a press release.

“DARPA demonstrations are always about learning, whether it’s in the interest of feasibility or practicality, and this time we certainly got new information that will further improve performance.” He added that the Navy and Air Force “will have access to the data we’ve collected, as they make development decisions for future high-speed weapons.”

Air Force Secretary Frank Kendall has voiced dissatisfaction with the progress of ARRW, which recently made a successful test flight, and he has said hypersonics, while important, should not be USAF’s top priority. He has said that while hypersonics are key to China’s strategy of denial of operations, the Air Force should not attempt to “mirror” that strategy and instead should concentrate on developing penetrating systems that can deter China.

Ukraine Says It Needs ‘Fast and Versatile’ Aircraft, Not the A-10

Ukraine Says It Needs ‘Fast and Versatile’ Aircraft, Not the A-10

Air space over Ukraine has been contested for more than five months, replete with advanced Russian fighter jets and near-universal Russian surface-to-air missile coverage that make penetration by aging Ukrainian Air Force MiG-29s and Su-25s both risky and dangerous.

For the duration of that time, Ukrainian Defense Minister Oleksii Reznikov has asked the United States and international partners for Western combat jets and the training to fly them. U.S. officials have weighed in, but they may not be suggesting the right aircraft, a Ukrainian defense official told Air Force Magazine.

“We have been requesting combat aircraft from our partners for a long time now,” Yuriy Sak, adviser to Ukraine’s minister of defense, told Air Force Magazine by phone from Kyiv on July 21. “We need Western-standard fighter jets. We need Western-standard combat aircraft.”

Reznikov again discussed Ukraine’s battlefield needs at a July 20 virtual meeting of the Ukraine Defense Contact Group led by Defense Secretary Lloyd J. Austin III.

Following the meeting, U.S. Air Force leaders indicated that conversations had begun on how to provide Ukraine with Western aircraft, such as older A-10s, but Ukraine says the slower aircraft won’t fill the mission set urgently needed.

To target Russian positions in Ukrainian territory, Ukraine needs “fast and versatile” combat aircraft such as the F-16—not slow-moving ground defense platforms such as the retiring fleet of U.S. A-10s, a proposition Air Force Secretary Frank Kendall entertained in comments July 20.

U.S. defense leaders such as Austin and Chairman of the Joint Chiefs of Staff Gen. Mark A. Milley have repeatedly recommended to President Joe Biden weaponry for Ukraine that meets evolving battlefield needs.

A-10s do not meet that bar, the defense adviser said.

“The answer to this question depends on the understanding of the needs of the Ukrainian Air Force in the current situation,” he said.

Sak gave the example of the U.S. decision to provide 12 High Mobility Artillery Rocket Systems (HIMARS), with an additional four promised by Austin at the contact group meeting.

“These HIMARS systems, they are really a game changer,” Sak said. “They’ve pretty much stalled the Russian offensive. We’ve been able to destroy 50 munition depots and command centers in the last 10 days.”

The advanced rocket system met the current battlefield need in the artillery war grinding out in the flat, eastern Donbas region. It also helps Ukraine to transition to NATO standard weapons.

The Ukrainian Air Force today is tasked with protecting the Ukrainian sky from enemy aircraft, drones, and missiles; and performing air support for ground forces to strike Russian manpower and combat equipment such as armored vehicles, artillery, and tanks.

“If we look at these needs of the Ukrainian Air Force today, it kind of leads us to conclude that the most optimal option would be something fast and versatile, and fast and versatile are F-16s,” Sak said.

U.S. Air Force Leaders Weigh In

In a July 21 fireside chat with the Washington Post’s David Ignatius at the Aspen Security Forum, Air Force Secretary Frank Kendall said A-10s do not provide a capability needed against America’s current adversaries. Ignatius then asked if the Air Force would consider giving Ukraine any of its aging fleet of A-10s.

“That’s largely up to Ukraine,” Kendall said.

“Older U.S. systems are a possibility,” he added. “We’ll be open to discussions with them about what their requirements are and how we might be able to satisfy them, but there are a number of possibilities.”

Kendall also referenced July 20 comments by Air Force Chief of Staff Gen. Charles Q. Brown Jr., who a day earlier at Aspen suggested a range of different fighter options for Ukraine.

“There’s U.S. [fighters]. There’s Gripen out of Sweden. There’s the Eurofighter. There’s the Rafale,” he said. “So, there’s a number of different platforms that could go to Ukraine.”

Sak said the Ukrainian Air Force has closely studied the advantages of the A-10, especially how it was used to support ground operations in Iraq, where it was able to target tank columns and equipment.

“They are a great support machine, very durable, very deadly. And the enemy cannot hide even behind tank armor when it meets A-10s,” he said. “But then, at the same time, they are slow. And, to operate them efficiently—and we know this from our pilots—they are really vulnerable to the enemy’s air defense.”

Sak argued that A-10s would be an easy target for Russian Buk missile systems and modern Russian MiGs.

“The function that could be hypothetically performed by A-10s in Ukraine is performed by Su-25,” Sak said.

Nonetheless, Sak said the A-10 has clear advantages over the Su-25, including three times the firing range, double the firepower, and the capability to shoot high-precision weapons.

Sak likened the proposition of receiving A-10s to the March debate whereby countries such as Poland and the Czech Republic would offer their older MiGs to Ukraine while asking the United States to backfill and modernize their fleet with F-16s. Ultimately, the United States dismissed a Polish offer, and Polish Defense Minister Mariusz Błaszczak later told Air Force Magazine that making the MiG delivery now would require a consensus among NATO nations.

At Aspen, Brown indicated that the idea of transferring MiGs to Ukraine had passed.

“It’ll be something non-Russian,” he said. “I could probably tell you that. But I can’t tell you exactly what it’s going to be.”

Sak said the other European options could meet Ukraine’s battlefield requirements.

“The criteria for us is the transition towards Western standard weaponry, and weaponry which can help us achieve our goals for aircraft, which is fast and versatile,” he said.

Sak said Reznikov also continues to lobby the United States and partner nations for pilot training. The initiative has support from members of Congress, who have recently increased pressure on the Biden administration. The House-passed version of the National Defense Authorization Act includes an amendment calling for $100 million to train Ukrainian pilots on American aircraft. The legislation does not specify the type of aircraft.

“It could be something like A-10s, as an example, which are a resource of ours that we have been saying fairly consistently that we need less and less of,” Air Force veteran Rep. Chrissy Houlahan (D-Pa.) recently told Air Force Magazine.

Houlahan is one of the lawmakers calling on the Biden administration to support pilot training, something Sak said can be done before a decision is made on aircraft.

“Why not start training our pilots in advance? Advance training is a very important issue so that we don’t lose time,” Sak explained. “So that by the time the political decision is made, we have pilots ready to fly those jets.”

Both Austin and Milley acknowledged at a July 20 briefing that pilot training had been discussed with Ukraine, but they said no decision had been made. A Ukrainian Air Force spokesperson previously told Air Force Magazine it has 30 pilots ready for training, and the Ukrainian Air Force expects that the experienced aviators could learn how to fly F-16s in six months.

The Ukrainian Air Force’s affinity for the F-16 as the fighter jet of choice for its future fleet remains clear as the country continues to press for air power to change the course of the conflict with Russia.

“F-16s are still something that our pilots dream about. F-16s are a global symbol of the aviation might and force,” Sak said. “We really hope that our pilots will be able to fly some of them to protect our country and show the world that Ukraine is a modern Army capable of protecting the whole of Europe.”

SDA Pushes Industry to Embrace ‘True Standards‘ for Satellites

SDA Pushes Industry to Embrace ‘True Standards‘ for Satellites

FARNBOROUGH, U.K.—As the Space Development Agency looks to capitalize on innovation from the fast-expanding commercial space market, its leaders have said they want to constantly have open competitions for the tranches of new satellites projected for every two years

Already, the agency has selected five contractors—Lockheed Martin, Northrop Grumman, York Space Systems, L3Harris, and SpaceX—across Tranches 0 and 1 for the Tracking and Transport layers, splitting the contracts each time in a bid to avoid so-called “vendor lock.”

But the SDA’s approach isn’t just increasing competition. It’s also helping to shape common standards across satellites that are much needed and could have far-reaching effects, a top commercial space executive told Air Force Magazine.

Indeed, the interoperability that SDA’s approach requires will represent a significant opportunity for the industry, Johnathon Caldwell, vice president and general manager of Lockheed Martin’s military space division, said in an exclusive interview at Farnborough International Airshow.

“One of the big things it’s challenged all of industry to do is to get down to common standards,” Caldwell said of SDA’s award. “When we talk about crosslinks, when we talk about how we will all get launched on the same rocket, it forces a healthy dialogue about coming to true standards. 

“When you’re only doing one or two satellites in a constellation of three or four … you can kind of size the problem. We’re talking about proliferated [low-Earth orbit], we’re going to be getting into the multiple hundreds of satellites.”

Indeed, SDA has already awarded contracts for more than 180 satellites as part of the initial two layers, and Lockheed Martin is responsible for a little more than 50 of them. With the cost of launches decreasing, the commercial space sector has experienced rapid growth.

At the same time, a lack of norms and rules in the domain have created a “wild, wild West,” Chief of Space Operations Gen. John W. “Jay” Raymond has said. Even within the Pentagon, standards for things such as cybersecurity for commercial SATCOM providers have been slow to roll out. And leaders have emphasized the need for more proliferation and interoperability, as opposed to the smaller number of so-called “exquisite” satellites built and launched in the past.

“Years ago, you might be designing a product for a particular service, and they might have unique needs that they’re very focused on getting … met,” Caldwell said. “We’re very responsive to our customers, responsive to the pressures they feel in their service. And that might have happened in stovepipes. And so you have systems that were developed that didn’t necessarily have interconnectivity.”

That’s all changed with SDA—and Caldwell sees the impact going beyond it, especially in an area such as data transport, which will likely be key to enabling the Pentagon’s hugely ambitious joint all-domain command and control (JADC2) effort.

“We see the future of transport as not just what SDA is doing, but the idea that those transport satellites will most likely talk to things like GPS. They will talk to things like [Advanced Extremely High Frequency]. There’ll be this entire mesh tapestry, if you will, of data transport, where the data—you really don’t have to define the path. The data will find its own way to the user who’s pulling for it,” Caldwell said. “And so these SDA contracts are providing the opportunity for industry to define those real standards so that they become kind of the DNA of how we’re designing, rather than an afterthought.”

Caldwell’s vision would entail satellites from different orbits connecting and communicating data—a view shaped by his belief that low Earth orbit, where the vast majority of satellites reside, is at risk of becoming overcrowded. It’s a belief that more and more experts are coming around to.

“There’s a growing awareness that you can’t just stick 30,000, 40,000, …100,000, 200,000 things in orbit,” Caldwell said. “Even if you break them up into different little shells, it’s going to get crowded.”

Even beyond the crowding issue, there are advantages to different orbits, Caldwell said.

“There’s always going to be a place in every layer for the right type of system,” Caldwell said. “And I think we’re kind of slowly coming around to that idea that OK, it’s really an integrated architecture we need. … LEO is like the super cool beach real estate right now, but not everybody wants to live on the beach. Some people want to live in the mountains. And we’ll get there. I think there’s a healthy dialogue right now.”

It’s not just data transport that could benefit from a multi-orbit approach, either. Caldwell said a recent Mitchell Institute report arguing for such an approach for missile tracking and warning “resonated” with him.

“I think people want the easy button, and so they want to say we can just do everything from LEO. And while I appreciate that people want easy solutions, supporting missile tracking and ultimately getting to the place of taking care of the missiles that are a threat to you, there’s no easy button,” Caldwell said. “I wish there was an easy button, but we’re firm believers that it takes a fully integrated architecture to get after a problem as hard as missile tracking and warning.”

Boeing Says It’s Ready to Help USAF ‘Accelerate‘ Delivery of E-7 Ahead of 2027 Timeline

Boeing Says It’s Ready to Help USAF ‘Accelerate‘ Delivery of E-7 Ahead of 2027 Timeline

FARNBOROUGH, U.K.—The Air Force’s aging E-3 Sentry fleet is on its last legs. The service has already asked in the 2023 budget to retire half the fleet, and its replacement, the E-7 Wedgetail, has been selected.

But now, lawmakers and observers are asking a new question: How quickly can the Wedgetail actually be delivered? The Air Force has said the first prototypes will be delivered by 2027—but Boeing, the contractor behind the airframe, says it is ready to help accelerate that process.

“There’s a lot of options, and we’d be happy to explore those with the U.S. Air Force,” Tim Flood, Boeing’s senior regional director of international business development for Europe and the Americas, told reporters at the Farnborough International Airshow when asked about the possibility of getting the Wedgetails into service faster.

The urgency to replace the E-3 is nothing new. Gen. Mark D. Kelly, head of Air Combat Command, said in October 2021 that he wanted the wanted the E-7 in the fleet “two years ago.” The degraded state of the E-7 fleet has made it such that it requires a “Herculean” effort just to keep mission capable rates around 50 percent, he added.

The airframe is so old and unreliable, there is already a capability gap, meaning retiring much of the fleet before the E-7 is ready won’t incur more risk than already exists, Gen. David S. Nahom, former deputy chief of staff for plans and programs, told Congress in May.

Yet at the same time, acquisition officials say they have moved fast in the process to select the Wedgetail but that they will not “rush” the process to get it into the fleet.

The current plan calls for funding for two “rapid prototypes,” one each in 2023 and 2024, followed by a production decision in 2025, two full years before the prototypes are delivered in 2027.

Members of Congress have expressed concerns about that timeline, pressing Air Force leaders on the possibility of moving those dates up. In May, Air Force Secretary Frank Kendall told the Senate Armed Services Committee that it takes two years to build the airframes, based on Boeing’s 737 Next Generation aircraft, and another two years to modify them, and that the U.S. may be stuck behind other customers with their order. Still, he left the door open that “there are things that we could do … to maybe get access to aircraft earlier one way or another.”

The Air Force has reportedly already decided, however, that it won’t pursue one of those potential ways. According to multiple media reports, Andrew Hunter, assistant secretary for acquisition, recently said the service will likely not look to buy used 737s and adapt them, a route taken by the Royal Air Force.

Yet even with that option off the table, Flood indicated that Boeing could still find ways to get the E-7s to the Air Force faster.

“First of all, the capacity to deal with 737 [Next Generations] is strong … So to incorporate the modification program, there is capacity there to accelerate,” Flood told reporters. “We will talk to the U.S. Air Force about how fast they want to move and how to … find ways to increase the schedule.”

Flood added that Boeing’s Renton, Wash., facility that manufactures 737s for military use would be able to increase production, based on customer demand. In addition to the E-7, Boeing’s P-8 Poseidon aircraft is based on the 737.

Pentagon Seeks Blended Wing Body Concepts for Possible New Cargo, Tanker Aircraft

Pentagon Seeks Blended Wing Body Concepts for Possible New Cargo, Tanker Aircraft

The Pentagon has put out a call for blended wing body aircraft concepts that could be applied to future military tanker and cargo aircraft as well as commercial aircraft, according to a solicitation posted by the Defense Innovation Unit.

The Pentagon wants “concepts of design of an advanced aircraft configuration that provides at least 30 percent more aerodynamic efficiency than the Boeing 767 and Airbus A330 families of commercial and military aircraft, enabling operational advantages such as increased range, loiter time, and offload capabilities,” according to the solicitation.

The Boeing 767 and Airbus A330 are the bases for the KC-46 and KC-30 Multi-Role Tanker Transport, the only strategic tankers now in production.

An Air Force Research Laboratory spokesperson said the solicitation “is not connected to the KC-Y program” but did not say whether it’s related to the KC-Z, which the Air Force has not defined but could be a stealthy aerial refueling aircraft. The solicitation did not mention stealth or low observability, but BWB-type aircraft, as “flying wings,” would likely have a much lower radar cross section than traditional types.

Air Force Secretary Frank Kendall has in recent months cautioned the defense industry that analysis indicates that the KC-Y requirement—a follow-on to the 179-aircraft KC-46 program—seems to be best met by buying more KC-46s, with additional capabilities. Lockheed Martin has said it wants to offer its LMXT tanker, based on the Airbus KC-30 MRRT, for a KC-Y competition.   

The blended wing body aircraft concept, because of its potentially large internal volume and aerodynamic efficiency, has been gaining interest from commercial airlines, cargo services, and the military for well over a decade. Boeing developed a BWB design for the X-48 program, which built and flew a subscale demonstrator in 2007 that received high marks. Lockheed Martin has also been promoting BWB concepts for tankers and cargo aircraft for a number of years.  

“When integrated with projected 2030 engine technology, this advanced aircraft configuration is expected to provide at least 60 percent mission fuel burn reduction compared to current-day technology,” the DIU said.

It wants responses to the RFI by Aug. 2.

The RFI noted that the Defense Department consumes 77 percent of all the fuel used by the federal government, “and the majority of that is attributed to fuel for aircraft sorties supporting global operations.” The DIU said that “decades” of research into BWBs offer efficiencies that could sharply reduce fuel burn “and increase operational effectiveness, enabling longer-range sortie and reduced fuel logistics/supply chain risks.”

The solicitation is unusual in that its Air Force sponsor is not the Air Force Research Lab or the Life Cycle Management Center, but the Air Force Operational Energy Office. The DIU is also partnering with the Pentagon’s sustainability enterprise.

The Air Force has said that it is reviewing whether it will extend the service life of the C-17 Globemaster III or seek a new aircraft as its main strategic/tactical transport. It has ruled out a “stretched” model of the C-17 that would increase its internal load, as the service did with the C-141 Starlifter. The C-5M Galaxy underwent a major upgrade and re-engining in the last decade that is expected to keep that type operational into the 2040s.

The DIU said it wants interested companies to submit concepts showing how they will use digital tools and processes to “design, develop, test, verify, validate and certify the system for a possible follow-on prototype build, live-fly, and production.” These are to include engineering models in the Systems Modeling Language (SysML) “in a format that will serve as the Authoritative Source of Truth (ASot) for the entire design.”

It also wants the concepts to have modular, open-systems approaches for integration and upgrades.

Responses are to include the outer mold line and general arrangement of the aircraft; its performance and subsystems; what the risks are and how they can be bought down; a requirement analysis; a system engineering plan; a management plan; a life-cycle cost analysis; and plans for software design and ground and flight test plans. All of these are to come with a technology readiness level indicating their maturity.

Beyond the military applications, the DIU is looking for an analysis of how these aircraft could be applied to the civilian marketplace, with a marketing strategy, target customers, market potential, and the competitive advantages of such designs. The respondents are also to explain how they would manage intellectual property, create a management team, and provide an explanation of “how the commercialization plan would help reduce DOD procurement and life-cycle costs, and increase national security.”

The responses also need to include a manufacturing plan—along with an estimate of when production facilities could be ready to being manufacturing—as well as how these aircraft would connect to the joint all-domain command and control network.

New AFCENT Commander Takes Over at Al Udeid

New AFCENT Commander Takes Over at Al Udeid

In a hangar flanked by F-15s and Apache helicopters at Al Udeid Air Base, Qatar, U.S. Air Force Lt. Gen. Alexus G. Grynkewich was sworn in as the new commander of the Ninth Air Force, Air Forces Central, July 21. Grynkewich will be responsible for a 21-nation area of responsibility, some 15,000 Airmen, and combat operations over Iraq and Syria.

Newly minted chief of U.S. Central Command, Army Gen. Michael E. Kurilla, was on hand for the ceremony, commending the former CENTCOM director of operations and referring to him by his call sign, “Grynch.”

“There’s no question that Grynch is the right leader with the right temperament and the right experiences to lead AFCENT at this moment,” Kurilla said.

The CENTCOM commander said Grynkewich is now responsible for the daily missions in support of the anti-ISIS Operation Inherent Resolve over Iraq and Syria; protecting air bases against attacks from unmanned aerial systems; and conducting airstrikes against Iranian-backed militias; and will perform deterrence missions in support of allies and partners.

As commander of the Ninth Air Force, Grynkewich oversees its 332nd, 378th, 379th, 380th, and 386th Air Expeditionary Wings; Combined Air Operations Center; and Air Warfare Center.

Grynkewich said the Central Command region remains geographically important and requires innovative solutions to new threats in collaboration with partners and allies.

“This is an amazing region with a rich history, vibrant cultures, and a geostrategic importance that is difficult to overstate,” he said.  “As we work together, we must find new ways to counter these new threats. As technology races ahead, we must identify the risks and exploit the opportunities the progress and change bring.”

Before welcoming Grynkewich to the command, Kurilla first acknowledged the progress made by outgoing Ninth Air Force commander Air Force Lt. Gen. Gregory M. Guillot.

“Under his command, this organization developed and matured a cloud-based capability to allow AFCENT to fight in the face of cyberattacks and kinetic strikes,” Kurilla said, noting that Guillot’s next assignment will be deputy director at CENTCOM.

Under his command, AFCENT also provided support from Gulf bases and carriers for the Afghanistan noncombatant evacuation operation in August 2021.

“You did not see the dozens of combat jets these men and women had overhead all the time. I can assure you the Taliban did see those aircraft,” Kurilla said. “The Taliban did see the AFCENT weapons trained on the Kabul airfield.”

Installs Begin on Production EPAWSS for F-15Es

Installs Begin on Production EPAWSS for F-15Es

Boeing has begun installing the Eagle Passive Active Warning Survivability System, or EPAWSS, on the first two F-15Es at the company’s San Antonio facilities, Boeing announced.

“Forty-three F-15Es will receive EPAWSS” under the first low-rate production batch, Boeing said July 21.  The EPAWSS “is also the electronic warfare system that will equip the F-15EX Eagle II,” it noted.  

Low-rate initial production of EPAWSS began in March under a $58 million contract from Boeing to BAE Systems, which developed the electronic warfare and jamming suite. A second LRIP contract is expected this year, and full-rate production is expected in 2023.

The Air Force plans to fit up to 217 F-15Es with the EPAWSS. In addition, all the new F-15EXs are being manufactured with EPAWSS installed, but the system isn’t expected to achieve initial operational capability until 2025. The Air Force planned for 144 F-15EXs, but the House reduced the fiscal 2023 budget from a requested 24 airplanes to 18.

While the Air force won’t say much about the capabilities of EPAWSS, it’s designed to give the F-15 pilot a means to detect, locate, and jam enemy radar, while also deceiving the adversary about the F-15’s exact position and heading. It uses “multispectral sensors and countermeasures,” according to BAE fact sheets, as well as high-speed signal processing, microelectronics, and “intelligent algorithms to deliver fully-integrated radar warning, situational awareness, geo-location and self-protection capabilities.”

Boeing called the system a “transformational overhaul to the survivability of the F-15.”

The EPAWSS “makes the most of mission effectiveness and survivability for the F-15 in contested environments,” said Prat Kumar, Boeing vice president for F-15 programs. The system “further strengthens a highly capable, lethal aircraft.” He said the F-15E and EX have “proven they can perform across a large-force environment to penetrate advanced enemy air defenses and improve mission flexibility.”

The two initial F-15EX aircraft, which are simultaneously undergoing developmental and operational testing, flew with EPAWSS in Operation Northern Edge last year. Boeing called the exercises “highly contested and complex,” and lessons learned from the war games “set the stage for future incremental improvements” in the system. Subsequent flight tests and exercises were run in October 2021 and February 2022.

Sources said the improved version of EPAWSS would kick in around the 60th installation; and that previous jets would be upgraded to the new configuration.

AFRICOM Nominee Calls for More ISR; SOCOM Nominee Names Uncrewed Systems

AFRICOM Nominee Calls for More ISR; SOCOM Nominee Names Uncrewed Systems

Nominees to lead U.S. Africa Command and U.S. Special Operations Command who testified before the Senate Armed Services Committee on July 21 described the Air Force assets they would need to better fight terrorism and counter influence by China and Russia.

Army Lt. Gen. Bryan P. Fenton is nominated to receive his fourth star and head SOCOM, replacing Army Gen. Richard D. Clark; and Marine Corps Lt. Gen. Michael E. Langley, the son of retired Air Force Master Sgt. Willie C. Langley, is nominated to receive his fourth star and head AFRICOM. Langley would be the first African-American four-star Marine and the first to lead the African combatant command (COCOM), replacing Army Gen. Stephen J. Townsend.

Both nominees cited the growing threat of terrorism in Africa and the importance of air support to prevent a threat to the U.S. homeland.

“I will need, as Gen. Townsend has, more ISR,” Langley said in response to a question from Sen. Joni Ernst, R-Iowa, about the growing threat of Al Shabaab in Somalia and the Horn of Africa.

“ISR is an active deterrent. ISR is the commander’s sense to make sense, and it underpins all activities,” he explained. “Al Shabaab has increased capacity, and that really is the first ranking as far as affecting U.S. interests and U.S. people. So, they have aspirations for external operations, transnational operations.”

Langley also said terrorist groups ISIS, al-Qaida, and JNIM are spreading across the Sahel, the Lake Chad Basin, and into West Africa, leading to instability that is further fueled by Russian mercenaries.

Confronting the threat will require a diplomat-like engagement with African countries and new partnerships, he said, responding to a question by SASC chairman Sen. Jack Reed (D-R.I.), who noted China’s aggressive moves to secure a naval port in the Gulf of Guinea.

“Working with other countries, I think we set the bar,” said Langley, who led Marine forces in Europe and Africa. “That’s going to be the biggest deterrent or assurance actions, as I mentioned, that’s going to deter China from trying to take over the west coast of the African continent.”

In Somalia, where Langley deployed in support of operation Restore Hope, he said the void created by the withdrawal of American troops in January 2021 could lead terrorist groups and America’s adversaries to move in. He cited how Russia’s mercenary Wagner Group filled a similar gap in Mali.

SASC ranking member Sen. Jim Inhofe (R-Okla.), who retires at the end of his term, warned committee members of rumors that Defense Secretary Lloyd J. Austin III plans to cut funding to AFRICOM and collapse the European and African special operations forces into one unit.

“I’ve heard from four different sources unrelated that these plans to downgrade are out there,” Inhofe said. “Given the growing strategy and strategic importance of Africa to the national security, this would be short sighted and would make implementing the NDS in Africa much harder.”

In contrast to rumored funding cuts to DOD’s Africa interests, much focus was given to how Fenton planned to strengthen special operations capacity in the Indo-Pacific as a deterrent to China.

“I would start with, the role is, in concert with the COCOMs, developing asymmetric, scalable options for the COCOMs via our special operators’ placement, access, and influence, presenting multiple dilemmas to the Chinese, in this case, and INDOPACOM, and also developing and strengthening the partner and ally piece that’s a comparative and competitive advantage for this nation,” he said.

Sen. Tom Cotton (R-Ark.) asked Fenton to describe what such partner building would look like.

“They would look like small teams in countries throughout the region,” said Fenton, who served as commander of Special Operations Command Pacific and deputy commander of U.S. Indo-Pacific Command.

Fenton said the teams would speak the language; be culturally attuned; have served in the region for years; develop, implement, train, advise, and assist plans; and present options both to the country and to the INDOPACOM commander.

The SOCOM nominee agreed with prior high-level defense assessments that China is preparing the capabilities for a Taiwan invasion “in this decade.”

Asked what lessons he drew from the Ukraine conflict, Fenton pointed to the early investment in Ukraine’s special operation forces, space-based data collection, and unmanned aerial systems (UAS).

“The use of open-source satellite imagery and modern technology, small UASs, is blunting and has denied Putin, in many ways, his desired objectives,” Fenton said.

The 30-year special operator was also asked what future investments he hoped to make to strengthen the command.

“I would start with capabilities that will enable us and advantage us in contested environments,” he said. “They may look like manned and unmanned systems, artificial intelligence, and certainly leveraging technology to give us an advantage.”

Loyal Wingman or ‘Untethered’ Drone? Why Not Both, Industry Leaders Say

Loyal Wingman or ‘Untethered’ Drone? Why Not Both, Industry Leaders Say

FARNBOROUGH, U.K.—As the Air Force moves forward with plans to team manned and unmanned systems in the future, the service might be best served by pursuing platforms that can function on their own as uncrewed aircraft—but are still capable of working as “loyal wingmen” to manned systems.

So said several executives of top defense contractors at the Farnborough International Airshow this week, emphasizing flexibility in how these new aircraft would be able to operate.

The question of how the Air Force should approach the concept of manned-unmanned teaming has been an open one. Air Force Secretary Frank Kendall has endorsed the idea of unmanned combat drones, designed to work with manned aircraft and “run plays” called by the pilot. He’s also called for up to five drones to fly alongside fighters.

Other ideas proposed have run the gamut—some have focused on just one “loyal wingman” to extend a fighter’s sensing range or potentially carry more weapons, while others have called for swarms of drones to go with each jet, each performing different functions. Some are based around the drones being autonomous, functioning independently, while others envision the drones performing preprogrammed tasks as directed.

“The Air Force has made comments around ‘loyal wingman’-type operations, manned-unmanned aircraft. We’re fully engaged with that,” Boeing Phantom Works vice president and general manager Steve Nordlund told reporters. “Our concept around that is it’s not about a platform and surrounding that platform with a swarm of UAVs. We believe in swarm technology. What we really want to do is be untethered from the platform and to be able have the autonomous vehicle go where it’s needed, regardless of where the platform is.”

Such an approach would provide “flux ability” for operators, Nordlund added.

“So if there’s an aircraft in a different vicinity that has a need, … the unmanned system can respond to that,” said Nordlund. “So that interoperability piece becomes really important; the level of quantity becomes really important; how that handoff happens is really important. So those are a lot of the things we’re working on, both procedurally as well as the technology.”

Nordlund’s endorsement of an “untethered” system echoes comments made by John Clark, the new head of Lockheed Martin’s Skunk Works program—earlier this month. Clark said the company had done analysis that determined that the best approach was a “distributed” team with uncrewed aircraft working in a “detached” way.

But Nordlund went further in saying the system should be set up so that the uncrewed aircraft can still come back to the manned one and act as a “loyal wingman” if needed.

“I want the flexibility to be able to serve that mission that is at hand that day and be able to do both of those. Tethered when it needs to be tethered, untethered when it needs to be untethered, is what I think our customer would desire to see,” Nordlund said.

One of the contractors that has frequently been connected to the “loyal wingman” concept is Kratos. Its Mako and Valkyrie unmanned aircraft have been tested as part of the Air Force’s Low-Cost Attritable Aircraft Systems and Skyborg platforms, demonstrating key characteristics such as autonomy, affordability, and the ability to fly alongside manned fighters, translating data.

And Jeffrey Herro, a senior vice president in Kratos’ unmanned systems division, also endorsed the idea of the drones being able to function on their own and within a teaming concept.

“I view these systems like we have as yet another tool in the arsenal of the pilot in command of a manned aircraft,” Herro said. “You might say this is another airplane. Well, it is, but it is actually just another toolset in his cockpit, potentially. It just happens to be off board in another airplane. … That’s one way to do it. These things can also be reasonably more autonomous and a standalone system to accomplish particular mission sets.”

Such flexibility could offer intriguing opportunities when it comes to planning and executing operations, added Robert Winkler, vice president of Kratos’ corporate development and national security programs.

“I think it’s really important, that idea of disaggregating sensors and platforms for a disaggregated strike package,” Winkler said. “And [then] it comes together at the right time. It doesn’t have to launch from the same location, but you can make that package on the fly.”
