GE Says New Engine for F-35 Possible by 2027, but Not on STOVL Version

GE Says New Engine for F-35 Possible by 2027, but Not on STOVL Version

Engine makers should be able to meet House defense policy bill language calling for a new F-35 powerplant based on the Adaptive Engine Transition Program by 2027, but only for the conventional takeoff versions, a GE Aviation executive said.

“We would be eager to step up to the challenge to meet the 2027 deadline” that the House version of the National Defense Authorization Act included, David Tweedie, general manager for advanced combat systems at GE Aviation, said in a Sept. 10 interview, adding that doing so is “certainly within the art of the possible.”

He said, “We were encouraged by both the direction [to the Joint Program Office] to provide a transition plan, as well as authorization for an additional $257 million of funding above the President’s Budget request, so we are encouraged on all those counts.”

After $4 billion in investment by the Air Force, through several successive technology programs, GE is in the final stages of testing its XA100 engine and Pratt & Whitney is also testing its XA101. The AETP program is a risk-reduction effort designed to make sure the technology is available if the Air Force wants to move on to a new powerplant for its fighters. Tweedie said the plan was always to develop an engine that could be applied to the F-35 at midlife, and to other, future aircraft, but not as a retrofit to the F-15, F-16, or F-22. The AETP engines were “optimized to the F-35 … from the beginning,” he said.

However, the AETP engine will not be able to power the F-35B, the short takeoff/vertical landing version of the Lightning II, Tweedie said.

While “we think we have a very competitive offering for the F-35A and the F-35C, … we did not design the AETP engine to integrate with the F-35B. It was beyond the scope of what we set out to do,” he said. While Tweedie did not comment on how hard it would be to adapt AETP engines to this application, he did say it would be “beyond the budget and timeframe” set by the House to accomplish.

Pratt & Whitney, which makes the F135 engine that powers the Joint Strike Fighter, argues that putting a new engine in the jet would cost $40 billion more over the remaining expected 50-year life of the program, chiefly in sustainment costs, because of the need to develop and maintain at least two engine logistics enterprises while continuing with the F135 for the F-35B. Pratt & Whitney says it can make modifications to its F135 that would be sufficient to meet all the Joint Strike Fighter’s future power and thrust needs, with margin; and that its AETP could not be adapted to the F-35, as it “will not fit” that aircraft’s engine space.

The AETP engines were developed because the Air Force recognized that engine technology of the 1990s had gone about as far as possible, and engineers were struggling hard to squeeze even a percentage point or two more performance out of it. The AETP engines add a third airstream to the traditional turbofan cycle, giving it better thrust and providing more air for cooling, while making it more fuel efficient in cruise.

The F-35 JPO does not have an engine roadmap for integration of a new powerplant in the jet, but creating one is likely to be on the agenda of the next top-level meeting of F-35 partners and users. The JPO has not committed to using AETP technology in the fighter.

“The … AETP is in the very early stages of development and is not currently an F-35 requirement,” an F-35 JPO spokeswoman said. The Joint Program Office is “working with the AETP program office and our industry partners to evaluate this new engine technology for possible use in the F-35.”

GE announced on Sept. 7 that it has begun testing the second all-up example of its XA100 AETP engine at its Evendale, Ohio, plant, which Tweedie said would likely be a “two-month effort, plus or minus.” The company says its version of the engine surpasses the F135 by 10 percent in thrust and 25 percent in fuel efficiency, along with a “significant reduction in carbon emissions.”

After GE has wrung out the XA100 at Evendale, it will be transferred to the Air Force for testing at Arnold Engineering Development Center, Tenn., where there is more sophisticated equipment that is only available to the Air Force.

It’s unclear how exactly the program will advance beyond this final stage; Tweedie said the contractors are “looking forward to what’s in the fiscal ‘23” budget request, as the 2022 version did not include out-years spending plans. “We have not seen a … finalized Air Force acquisition strategy,” he said.

But in a Sept. 7 Defense News conference, Air Force Chief of Staff Gen. Charles Q. Brown Jr. said it’s important to press on with it, even if it isn’t used in the F-35.

“You’ve got to continue the R&D [research and development] … so that you have options in the future,” Brown said. “If we stop the R&D on this, we basically shut ourselves off from having an option to go forward.”

GE would “need to see something in the ’23 budget to keep this momentum going,” Tweedie said of Brown’s comments, paraphrasing Brown as saying, “’You can’t stop.’ And that’s true of any major development effort. There’s a lot of cycle time lost if you bring that effort to a complete halt.”

The Air Force has had superior fighter engine technology for generations, Tweedie said, and “10 years ago, the Air Force came to industry and said, ‘We need to earn that again; we need the next generational leap in technology.” The AETP program, and other such projects before it, were focused on being “ready to go launch that next full-scale engineering and manufacturing development program … We’ve met the Air Force’s objective to burn that risk down.”

Lockheed Martin, builder of the F-35 fighter, has worked with both GE and Pratt & Whitney throughout the AETP program to ensure that what they were developing would fit in the F-35; that “access panels, and all the other things” needed for service and maintenance would line up, Tweedie said. Lockheed Martin “has been an active participant in this program from Day 1,” and the resulting powerplants should, with development, “fit seamlessly” into the jet.

20 Years Later: Reflections and Lessons from a General Who Smelled the Smoke on 9/11

20 Years Later: Reflections and Lessons from a General Who Smelled the Smoke on 9/11

The building shook for only an instant and the soot from the smoke was clean within 48 hours, retired Lt. Gen. David A. Deptula recalled two decades after the 9/11 attack on the Pentagon. But America’s national security priorities had been lost in the fog of war for a generation. Only now is strategy again aligning with threat.

An externally focused defense strategy turned to the homeland after the al-Qaida attacks, consolidating intelligence and protecting the nation against another terrorist attack, but mission creep led to strategic errors that would set the nation behind adversaries, said Deptula, now the dean of AFA’s Mitchell Institute for Aerospace Studies, in an interview with Air Force Magazine as he reflected on the 20th anniversary of 9/11.

On the morning of Sept. 11, 2001, then Maj. Gen. Deptula was dressed in his blues sitting at his Pentagon office at 5D156. He was director of the Air Force 2001 Quadrennial Defense Review. After the attack, he would be called in to design the air response against the Taliban, putting him at the center of an evolving assessment of global terrorist targets against an evasive enemy, hampered by burdensome restrictions and patchy intelligence.

Deptula was two corridors down from where American Airlines Flight 77 would strike the west wall of the Pentagon.

“I’m sitting at my desk, and I get a call from my deputy, Brig. Gen. Ron Bath… He said, ‘Hey, General Deptula, turn on the TV,’” Deptula recalled.

American Airlines Flight 11 had struck the North Tower of the World Trade Center at 8:46 a.m.

“It was just a beautiful day, up and down the East Coast. There wasn’t a cloud in the sky; crisp, wonderful, blue sky day,” Deptula recalled, wondering how a pilot could hit the building.

“Then, as I’m watching, wham! Here comes the second, and immediately, everyone who did watch it, when they saw the second airplane, it’s like, ‘This isn’t an accident,’” he said.

“This is an intentional attack,” he continued. “And the next thought that went through my mind, I’ll always remember this as well: ‘You know, the Pentagon would make a logical third target.’”

The Building Shook for an Instant

Thirty-four minutes after Deptula watched American Airlines Flight 175 crash into the South Tower of the World Trade Center, he heard a muffled explosion and felt a momentary quake.

The Pentagon had been hit by American Airlines Flight 77.

“The building shook, just for an instant,” Deptula recalled, ascertaining what had just happened. “The alarms went off almost immediately.”

The two-star directed staff to account for everyone in his division and once the task was complete, he dismissed them for the day. He himself was dismissed while critical staff, including the Joint Chiefs, assembled at the alternate command center at Bolling Air Force Base, now Joint Base Anacostia–Bolling, in Southeast Washington, D.C.

The remainder of the afternoon was a hectic effort to get home: Walking past closed Pentagon exits, observing smoke and fire from across the inner courtyard, unable to reach his wife with downed cell service. Finally, Deptula walked out the Pentagon river entrance and across the street to the marina, where he watched news reports on a small portable TV and conducted an interview with Washington Post reporters while waiting for a lift home.

“One of the biggest things I noticed was the quiet, the silence,” he recalled. “It was quiet. Black smoke billowing over the other side of the Pentagon, the opposite side from the river entrance, and then here are these two F-16s orbiting overhead. That’s why I say, ‘This was surreal. It’s quiet. The Pentagon’s on fire, two Air Force F-16s doing combat air patrol over Washington, D.C. Just eerie.’”

Deptula went into work at the damaged and soot-covered Pentagon the following day, only to be sent home until the intact part of the structure could be cleaned and secured.

Returning to work on the Air Force QDR seemed distant with the nation poised to strike back at an as-yet undefined enemy.

“The thing that you begin to think about is, ‘Who’s responsible for this? Where are they located? What are the options for response?’” Deptula recalled. He had already begun to share his operations experience as principal attack planner for Desert Storm in the Pentagon’s Checkmate wargaming center. There, he heard some of the ideas under consideration by U.S. Central Command contingency planning cells.

Then, Air Force Chief of Staff Gen. John P. Jumper called Deptula into his office.

“‘I just got a call from Chuck Wald, the 9th Air Force Commander,” Deptula recalled Jumper saying. “‘He’d like you to deploy to Southwest Asia to become the commander of the [U.S. Air Forces] Central Combined Air and Space Operations Center to design the response, plan the response, and help in the execution of our response. Do you want to go?”

Striking Back at the Taliban

Deptula settled into his new role at Prince Sultan Air Base, southwest of the Saudi capital of Riyadh, within days of the 9/11 attacks. He would be responsible for designing the initial attacks on the Taliban and al Qaeda that commenced on Oct. 7, 2001.

Many strategic options were on the table from a cover for invading Iraq and removing Saddam Hussein to launching simultaneous counter-terrorism activities globally. As intelligence came in, options were refined. At one point, the United States even proposed working together with the Taliban.

“Very early on, we offered the Taliban the option to work with us to help us kick out al-Qaida,” Deptula said. “Then it became evident that they did not want that. Then we kind of raised the stakes in the context of, ‘Well, if you’re not going to do that, then you are liable for protecting our adversary and will come under attack as well.’”

CENTCOM planners wanted to assure that the people of Afghanistan knew this was not an attack on them, but on the Taliban who were harboring al-Qaida.

But limitations were plentiful, and strategic errors ensued.

“We could not drop a bomb in Afghanistan without approval of the four-star commander of Central Command, which was ridiculous,” Deptula remembered. Infrastructure was off limits.

The command wanted roadways and lines of communication to be in place to move humanitarian assistance to the people of Afghanistan.

The restriction led to one of “the most grievous strategic errors” of the war, Deptula recalled, allowing Taliban leader Mullah Omar and the senior most Taliban leadership to enter a compound in Kandahar and not strike.

“This is like manna from heaven to combat planners because I can take out the senior Taliban leadership and all of their senior staff on the first night of the war,” Deptula remembered. “I’m talking to the commander of the Predator outfit going, ‘What the hell is going on? Why is this taking so long to get approval?’”

Approval did not come. Concerns about mud huts within the collateral damage circle prevented the strike.

Nonetheless, the coordination of airpower with the “light touch” of special operations forces and the indigenous forces of the Northern Alliance led to the collapse of the Taliban government by December.

“We’d already accomplished our critical U.S. national security objectives in Afghanistan,” Deptula said, noting his own departure in mid-November.

“We’d removed the Taliban from power. We had worked to assist a government friendly to the United States and our interests in their place, and we’d eliminated the al-Qaida terrorist training camps inside Afghanistan,” he said. “What we should have done was [say], ‘See you later, have a nice life. If you do it again, we’ll be back.’”

‘Unobtainium’ Mission Creep

The mission in Afghanistan had been accomplished even before Central Command finished deploying its land forces. Instead of fighting, the military took a non-military role, Deptula assessed.

“By the time they got into theater, they realized, ‘OK, the Taliban are gone. Friendly government. Al Qaeda is gone. Now, what do we do?’” he said. “So, in the largest example of mission creep, they sought to win hearts and minds and change a collection of sixth-century tribes into a modern Jeffersonian democracy, which is what we’ve been trying to do for the last 20 years. But it’s unobtainium. Nor is it a military mission or role.”

Institutional equities butted heads, Deptula opined, as the Army fought to “prove their relevancy” in the wake of a decade of swift air successes that preceded 9/11, from Bosnia to the Gulf War. The investment and commitment of U.S. forces in Afghanistan would bog down the American military for two decades while adversaries like China invested in military modernization.

“9/11 happened. And it had an enormous strategic effect on the government and the military of the United States,” Deptula offered.

America’s defenses had always been faced externally. Important changes were made. The Department of Homeland Security was stood up, the Intelligence Community was united under the Director of National Intelligence and the Transportation Security Administration was established.

“We are more attuned to terrorism as a critical national security threat than we ever have been before,” Deptula said.

In Afghanistan, changes in military strategy hampered the American force.

“When we shifted from a strategy of counterterrorism to one of counterinsurgency, we shifted from a set of objectives that were in the U.S. critical national security interest to a set of objectives that were not, and that’s very frustrating,” Deptula said. “We shouldn’t get counterterrorism confused with counterinsurgency and getting involved with nation building and trying to change other nations into our image.”

The United States neglected future threats by continuing to push for total success in Afghanistan, he said.

“As the world’s sole superpower, we need to be able to be prepared to deter, and if necessary, defeat threats across the spectrum of conflict, from humanitarian assistance all the way up to global thermonuclear war,” Deptula said. “The pendulum swung too far.”

Whiteman B-2s Integrate with Norwegian F-35s

Whiteman B-2s Integrate with Norwegian F-35s

A pair of U.S. Air Force B-2s integrated with Norwegian F-35s over the North Sea on Sept. 8 as part of a recent Bomber Task Force deployment.

The mission was “designed to test escort procedures, stand-off weapon employment, and the suppression and destruction of air defenses,” U.S. Air Forces in Europe-Air Forces Africa said in a press release. During the flight, the two different aircraft were able to link and use fifth-generation data-sharing capabilities.

“The mission demonstrates the value of our continued presence and relationships,” said Gen. Jeffrey L. Harrigian, U.S. Air Forces in Europe-Air Forces Africa commander, in a statement. “What our collective Airmen accomplish on these missions is vital to our alliance and maintaining agility as we move into the future.”

The three B-2s, from the 509th Bomb Wing at Whiteman Air Force Base, Mo., arrived at Keflavik Air Base, Iceland, on Aug. 23.

This marks the second time in the last year and a half that B-2s from Whiteman have integrated with F-35As from the Royal Norwegian Air Force. Back in June 2020, the 509th Bomb Wing conducted a “long-range, long-duration” training mission with the fighters north of the Arctic Circle.

Since arriving in Iceland, the American bombers have also flown over RAF Fairford in the U.K. and integrated with F-15Cs from the 48th Fighter Wing based out of RAF Mildenhall over the North Sea, according to released photos.

The concept of deploying bombers to new locations as part of task forces, as opposed to a continuous presence outside the U.S., was first introduced in April 2020 and was championed by then-Global Strike Command boss Gen. Timothy M. Ray.

In February, Ray said the Bomber Task Forces had increased morale and readiness, provided new training opportunities, and strengthened partnerships while projecting the Air Force’s global reach and power. At the time, he said the service was planning on “expanding beyond the normal” locations such as Fairford, U.K.; Diego Garcia; Moron, Spain; and Guam.

DOD Finalizing First-ever Digital-only Tech Conformance Plan for New Satcom Terminals

DOD Finalizing First-ever Digital-only Tech Conformance Plan for New Satcom Terminals

The Department of Defense is finalizing a new technical reference architecture (TRA) for satcom terminals it will buy—a highly detailed description of the engineering requirements for the devices, which maintain global two-way satellite communications for aircraft and other deployed forces.

And for the first time, the TRA, typically a document hundreds of pages long, will instead be produced in digital form, according to Michael Dean, who heads the satcom team for the DOD’s chief information officer.

The digital tool being developed in partnership with the Defense Information Systems Agency (DISA) was “pretty cool,” he told Air Force Magazine on the sidelines of the Satellite 2021 conference. Potential vendors could load in data about the terminals they manufacture and quickly understand where their products might fall short, rather than having to pore over hundreds of pages of a PDF. “You just click … and it kind of tells you that, ‘no, you’re out of tolerance, or yes,’” you’re in conformity, Dean said.

The digital TRA tool uses the same model-based systems engineering (MBSE) approach that powers digital twin technology—already used by the Air Force to predict engine performance, test satellites for cyber vulnerabilities, and teach artificial intelligence to fly planes.

The TRA tool will also gather data required for the DOD’s rigorous certification process, which ensures satcom terminals actually conform to their own specifications. “That can take a long time,” Dean said, so the tool was designed to capture as much of the data required for certification as possible. When vendors “build their terminal design, and they plop it in [to the digital TRA], then when the folks that do the assessments … look at it, a lot of the work is already done for them.”

The TRA is currently undergoing an internal approval process, Dean said, but he hoped to have it finalized by the start of 2022. “So we’re in the final stages—it seems to be on track,” he said, adding that he’d know by November if they would make their end-of-year target.

One new requirement in the TRA, Dean said, would be for an automated registration function for new satcom terminals, part of an effort to get a better handle on DOD satellite communications called the satcom enterprise management and control environment.

Dean explained that the DOD currently relies on manually compiled spreadsheets to keep track of its terminals: “It’s a data call—it’s a manual process. It’s very labor intensive.” Because all the data was manually entered, it was not authoritative. “It’s hand jammed—you can make mistakes. And so you’ve got bad data. You’ve got duplicated data,” he said.

That matters because terminals need access to a limited resource—satellite bandwidth—which has to be apportioned out. Different terminals have varying capabilities and might employ different frequencies. Without authoritative data on which terminals are out there and what capabilities they have, commanders can’t prioritize resources efficiently, Dean said.

“Our terminal segment is the tail that wags the [satcom] dog … I’ve got a lot of terminals that aren’t very interoperable. Some of them are digital. Some of them are analog. Some of them speak certain protocols—some of them don’t.”

An authoritative catalogue of terminals, compiled automatically as the new terminals come online, would let the DOD “leverage certain enterprise capabilities—automatic resource allocation, for example,” Dean said, allowing algorithms to dole out bandwidth.

The 9/11 Mission was to Take Down Any Unresponsive Aircraft. The Only Option: ‘Fly Into It’

The 9/11 Mission was to Take Down Any Unresponsive Aircraft. The Only Option: ‘Fly Into It’

The first day back at work wasn’t supposed to go like this. The 121st Fighter Squadron had returned on Saturday from a Red Flag deployment in Nevada; Monday was a day off.

Now, on Tuesday, District of Columbia Air National Guard squadron leaders were meeting at Andrews Air Force Base, Md., to set training priorities. Heather Penney, a green first lieutenant, was in the meeting because her secondary duty was squadron training officer.

The session was interrupted when someone opened the door a crack to let the assembled officers know an airplane had flown into the World Trade Center.

“And we all looked outside, and it was a crystal-clear, blue September Tuesday morning,” Penney recalled. The weather was likely the same in New York, and the pilots speculated that either “someone totally pooched [fouled up] their instrument approach,” or some small aircraft sightseeing on the Hudson had made a really bad turn.

The group returned to its meeting. A short while later, the door was opened again, this time wide, and a noncommissioned officer said a second aircraft had flown into the WTC, “and it was on purpose.”

With urgency but professionalism, the group looked at each other and asked, “What do we do now?”

Over the following hour, unit leaders tried to get orders to act. While state Air Guard units get instructions from their governors, D.C. has no governor, so the Guard takes orders directly from the President. Further, the base was not an alert facility, so it was not tied in with the North American Aerospace Defense Command. The Secret Service has a heavy presence at Andrews, however, because it is the operating base for Air Force One.

Brig. Gen. David F. Wherley Jr., 113th Wing commander, ordered his Airmen to begin preparing for a possible launch. He called his Secret Service contacts, seeking authorization for an improvised combat air patrol mission.

As they hurried to pull on their flight gear in the life support shop, Penney and her flight lead, Maj. Marc Sasseville, had a perfunctory conversation about what they would do if they found the inbound airliner they had been told was on its way toward Washington.

They would be launching with nothing on board but about 100 rounds of training ammunition—simple bullets with lead tips, not the usual 20 mm high-explosive incendiary rounds used in combat. AIM-9 Sidewinder air-to-air missiles were being unpacked and built up at Andrews’ weapons area, but it took time to assemble the missiles, and the cart that transported them from the far side of the base moved at a top speed of just nine miles per hour. The Sidewinders would have to wait for a second flight.

Penney, remembering an accident investigation that her father had participated in, recalled that 737s simply dropped from the sky if they lost their tails, leaving “a very tight debris field.”

The mission here would be to bring the airliner down causing as few casualties as possible on the ground, but primarily to make sure that it did, indeed, crash without reaching its target.

The training ammunition wasn’t going to be enough to do the job, Penney explained, “even if you’re a perfect shot.” There was really only one way to take down a large airplane under these circumstances.

“Fly into it,” Penney said.

Sasseville said he would ram the cockpit; Penney intended to take out the tail. “I know for sure that if I take off the tail, that it will just go straight down,” so she intended to “aim the body of my airplane” at the empennage.

Penney was hoping to have enough time to eject after the impact, but was keenly aware that she’d have to stay with the F-16 until it struck the airliner.

“It was very clear that, yeah, this was”—Penney declined to finish the thought—probably going to be a one-way mission.

Wherley soon received orders from the Secret Service to intercept any approaching aircraft and keep them away from an eight-mile circle around downtown. “That allowed an ROE-build,” said Wherley in a 2004 interview, referring to rules of engagement.

Penney and Sasseville powered up immediately.

Normally, an F-16 preflight took 10 to 20 minutes. Now, she and Sasseville were rolling within seconds; the crew chiefs were “still under the jet, pulling pins” even as the fighters surged forward, she said. In two minutes, at full afterburner, they were airborne.

It was about 10:40 a.m., just an hour after American Flight 77 had struck the Pentagon, and Sasseville and Penney knew they had a grim mission. At least one airliner was still believed inbound toward Washington, D.C. Their job was to get over the city as soon as they could and act as the “goalie” CAP: to bring down any aircraft ignoring orders to turn away.

As Sasseville and Penney screamed skyward, banking toward the Potomac River and Washington, Penney said the whole scene was dream-like. In the center of an extremely congested triangle of commercial airports—Reagan National and Dulles in Virginia, and Baltimore-Washington in Maryland—D.C. was typically abuzz with airliners, business jets, and general aviation airplanes. Sometimes, it could take two minutes to get departure clearance from Potomac Control—an eternity in a gas-guzzling F-16.

By midmorning on 9/11, however, nothing else was up. “It was eerily silent,” Penney recalled. “That part was very surreal.”

Sasseville and Penney flew over the Pentagon, then proceeded west-northwest, as instructed, looking for the inbound airliner. In the confusion of the morning, they were looking for United Airlines Flight 93, which, unknown to them, had already crashed in Shanksville, Pa.

F-16s from the North Dakota ANG soon arrived and also took up station, having flown up from Langley Air Force Base, Va. The D.C. and North Dakota F-16s set up a high-low CAP, with the Fargo jets staying above 18,000 feet, looking for inbound threats from over the ocean, while Penney’s flight stayed low, on the lookout for threats trying to sneak in at low altitude, as the previous attacks had done.

Because they had been dispatched by NORAD, the Fargo Vipers were joined by a tanker, and all the F-16s over Washington took turns refueling.

They remained up for four hours, and when Penney and Sasseville landed back at Andrews they left plenty of other interceptors over the city. Upon landing, they were whisked to a room “with more generals than I’d ever seen in my lifetime,” Penney said.

“We stood at the head of an oval table in front of the entire group, and it was standing room only, and they asked us all sorts of questions about the morning and the sorties, and what we had seen,” she said. It was heady stuff for a first lieutenant who had only been assigned to the base for nine months.

Almost immediately, the two F-16s relaunched—now fully armed—to fly another four-hour mission over the capital.

During this second sortie, they received instructions over the encrypted radio to escort Air Force One, which was inbound on its way to Andrews. “I then flew point, leading the package back,” Penney said. “The first sortie, we were far more focused on doing the task at hand,” she said. Hours later, it was still “hard to believe” what had happened.

Penney spent some of the time on the second sortie above the Pentagon, looking down at it with her jet aircraft’s infrared targeting pod, trying to get the events of the day to seem more real.

The D.C. Air Guard served as Washington’s CAP resource for the following two weeks, but of the 32 pilots assigned to the unit, only about eight were full-timers. Many of the traditional Guard pilots were airline pilots “stuck in different parts of the country” when air travel was abruptly halted on 9/11. For the D.C. Guard, the air defense mission represented “24-hour operations with decreased manpower,” Penney said, “very work intensive.”

The situation didn’t leave much time for reflection. While it was a “dramatic experience,” she became turned off by “the melodramatic media attention,” and postponed much personal reflection.

“I really didn’t process or think through all of that until a couple of years ago,” Penney said. However, as to the notion of having to take down an airliner with innocents aboard, “it was so abundantly clear in the moment that, while it would have been tragic and unfortunate, the moral choice was obvious.”

She said that at no point “did I feel conflicted, like, ‘Could I really do this?’”

The “total heroes” of the air action, she said, were the passengers on Flight 93 who ultimately made the goalie CAP unnecessary.

“What they did was courageous,” Penney said. “And I think for them it was also obvious, once they realized what was going on.”

Space Force Readies Long-Delayed Cybersecurity Standards for Commercial Satcom Providers

Space Force Readies Long-Delayed Cybersecurity Standards for Commercial Satcom Providers

Within 30 days, the Space Force office that buys commercial satellite services for the Department of Defense will publish a timeline for the implementation of new cybersecurity standards that private-sector satellite communication providers must meet if they want to compete for contracts to supply the Air Force and other military services, according to officials and industry executives.

“By the end of September, we want to put that [timeline] out to industry so that they can start planning internally to be able to accommodate for any cost impacts it might have for them,” Jared Reece, a program analyst with the Space Force Commercial Satellite Communications Office (CSCO) told Air Force Magazine on the sidelines of the Satellite 2021 conference.

First publicly mooted in 2019, the much-delayed Infrastructure Asset Pre-Assessment (IA-Pre) program will require satcom providers to get on-site, third-party assessors to validate their compliance with cybersecurity standards before they can bid on CSCO contracts to sell their services to the U.S. military, Reece said.

The Space Force already maintains a list of certified third-party assessors—known as Agents of the Security Control Assessor (ASCA)—who help validate contractor compliance with existing security standards under the DOD’s Risk Management Framework. “The preference is to use those,” said Reece, “because they’re validated providers of those assessment capabilities.”

The move to finally implement IA-Pre comes amid growing concerns that near-peer adversaries could use cyberattacks to blind or cripple commercial satellites on which the U.S. military increasingly relies for its communications.

The IA-Pre standards have yet to be published, but industry sources said they will be based on those set by the National Institute for Standards and Technology (NIST) in its Special Publication 800-53, with an overlay of additional measures specific to the space sector. Reece said the standards would cover spacecraft, ground stations, teleports, and vendors’ business IT networks.

Industry representatives have been involved in drawing up the plans for IA-Pre and welcomed the news. “We’re very encouraged that from the national level down, we’re actually seeing this emphasis on ensuring that we’ve got a [satcom] network, which is provided in the most secure posture, and is evaluated accordingly,” said Rebecca Cowen-Hirsch, senior vice president of U.S. government strategy and policy for U.K.-based satcom provider Inmarsat. IA-Pre would provide CSCO the capability to “actually discriminate between those [providers] that have made the investments versus those that are just providing bare minimum [security] capability.”

Indeed, Reece said, the aim of IA-Pre was to “level the [cybersecurity] playing field between MilSatCom [the military’s own satellite communications] and ComSatCom [the commercial capabilities it buys in from the private sector], as they start to be integrated more and more in the warfighter’s toolbag.”

By creating a kind of “approved products list” of space assets that are pre-certified as cyber secure, CSCO also hopes to speed the acquisition process and reduce the administrative burden on both the contractors and the Space Force, Reece said.

“We need to have a good understanding of [the security posture of] what we’re going to be buying,” he said. “And we need to do it beforehand. So that we have it and, when we need [to buy services], we can do it quickly.”

Currently, he said, the self-assessment required as part of the acquisition process is slow and repetitive. Because CSCO often issues contracts for an individual customer—a particular combatant command, for instance—that are bid on by the same group of suppliers, “We end up doing assessments of the same solution over and over again in the acquisition cycle, which slows us down.”

Earlier this year, Space Force Vice Chief of Space Operations Lt. Gen. David D. Thompson told the 2021 C4ISR Conference that the role of CSCO could be expanded to cover the purchase of remote sensing, data analysis, and ISR services, as well as communications.

Reece noted that, as it prepares for that change, CSCO is weighing whether it needs to create specific new IA-Pre standards for Earth observation imagery and other intelligence, surveillance, and reconnaissance satellite services. But he said the aim would be to maintain a common framework for all satellite services, with new requirements only where additional services diverged from satcom in the technologies they used.

“They’re still spacecraft. There’s still data. There are a number of things that apply [to both satcom and ISR services], so the only thing you really have to look at in depth is the deltas,” he said.

Pratt Pushes Alternative to New Adaptive Engine for F-35

Pratt Pushes Alternative to New Adaptive Engine for F-35

Modifications Pratt & Whitney is proposing to its F135 engine can improve thrust and efficiency and would be far less costly than giving the F-35 fighter a new powerplant developed through the Adaptive Engine Transition Program, the engine maker said.

Jennifer Latka, Pratt & Whitney’s vice president for the F135 engine program, said the AETP technology is not compatible with the Marine Corps’ F-35B. That would necessitate two different alternative engines for F-35. The whole effort could add up to $40 billion over the 50-year life of the program, she said in an interview with Air Force Magazine..

The House version of the 2022 National Defense Authorization Act would require the F-35 Joint Program Office to pursue a strategy to incorporate an AETP engine into the F-35 fleet beginning in 2027. Congressional sources said one of the goals is to drive down the cost of F-35 engines by creating a competitor to Pratt & Whitney. GE, which is high on the AETP technology, is eager to offer its XA100 as an alternative. Pratt, owned by Raytheon Technologies, has also developed an AETP engine, the XA101.

The Air Force invested in AETP to try to get more range and thrust from an engine about the size of the F135. The idea is to have both the fuel economy advantages of the turbofans used by large airliners with the high-pressure compression needed to maximize speed for a fighter. By enabling the engine to adapt on the fly, the program sought to gain the best of both worlds.

Latka said the F-35B’s unique short take-off and vertical landing lift system can’t accommodate the AETP engines. To create competition with GE, she said, two variants of each company’s engine would be needed, with parallel repair and supply chains. That contributed to Pratt & Whitney’s $40 billion cost figure, she said.

The Air Force’s Program Executive Officer for fighters and advanced aircraft, Brig Gen. Dale R. White, was similarly skeptical in an August press conference. Although he has no role in the F-35, he said, “trying to change a powerplant in … a fielded system is extremely complex. … You have to think about what the return on investment might be.”

Pratt & Whitney submitted a pair of proposals for modernizing the F135 engine to the JPO in March. The plans would improve thrust and range by more than 10 percent each and give the F-35B a 5 percent boost in vertical lift and a 50 percent improvement in thermal management, the company said. Heat damage has been a concern with these engines, and less heat could also potentially improve stealth performance.

The JPO asked for the study “at the end of 2020,” Latka said. The proposals can be “tuned” based on JPO requirements, she said, and the changes can be “cut in” to production in 2028. Once installed, there will also be “some margin” for growth.

There would be little industrial impact, as the Enhanced Engine Package, or EEP, could “drop into production as a retrofit … So it relies on the exact same infrastructure, and the same sustainment network, that we currently … rely on.”

“It is very well understood, now, across the board” that the F-35 needs an engine upgrade, Latka said. “We will need to modernize the engine, hopefully, one time over the life of the JSF program,” she said. Engine capabilities “have to be commensurate with the capabilities of the aircraft.”

While she could not discuss the Block 4 improvements that are contributing to the need for greater performance, it is understood that the F-35 needs to carry heavier payloads and weapons and that powerful sensors and electronics need additional cooling. Without a better-performing engine, “they can’t use the jet the way it was intended,” she said, quickly adding that “there are no deficiencies” in the F135’s performance as it stands today. “If anything, the engine is already overperforming on the original spec … This is all about growth.”

One advantage of the AETP engine, according to GE, is its third airstream, which its officials say can be used to help cool the F-35’s electronics.

Pratt & Whitney is investing millions, meanwhile, to try to drive down sustainment costs for its engine, a major contributor to the F-35’s high operating costs. “We get it,” she said. “Affordability is the existential threat to this program.”

She continued: “We’ve taken 50 percent out of the unit cost” of the F135, she said. Improvements would reduce costs further, taking 36 percent out of the cost for the initial shop visit, she added. “That’s where the big bills come,” she added, because parts of the hot section hardware have reached end of their service lives.

“We know how to take cost out … Our whole commercial profile is ‘power by the hour,’” Latka noted.

Absent such improvements, the services will need to run the engines hotter to make use of Block 4 capabilities, and while they can handle it, “that means … the engines come in for maintenance” more frequently, increasing sustainment costs.

Latka said Pratt & Whitney’s proposed improvements have nothing to do with achieving the Air Force’s goal of cutting operating costs to $25,000 per hour by 2025. The upgrades are also not specifically intended to create more electrical power for onboard systems, she said.

The JPO holds a meeting of F-35 partners, operators, and other stakeholders twice a year to discuss future plans, and propulsion is likely to be on the agenda for the next meeting.

“We need to crystallize on what the requirement is,” Latka said. “And then we figure out what the most cost-effective solution is once we understand that requirement.”

Latka did not comment on the suitability of Pratt & Whitney’s XA101 for the F-35, except that the engine was “always intended … to be a sixth-generation” powerplant for sixth-generation fighters. The F-35 is a fifth-generation fighter. A Pratt & Whitney official said it began testing the XA101 this spring; GE said it began testing its XA100 in December 2020.

“There’s a significant amount of risk that comes with brand-new technology, and that would require a … tremendous amount of validation to be done,” Latka said. “We’re saying, the AETP is not the right fit for the F-35.”

Austin Warns Al-Qaida May Reemerge in a Taliban-controlled Afghanistan

Austin Warns Al-Qaida May Reemerge in a Taliban-controlled Afghanistan

Capping his Gulf state tour in Kuwait, Defense Secretary Lloyd J. Austin III visited Marines present during the Aug. 26 Kabul airport attack and warned that Al-Qaida may emerge in the chaos now enveloping Afghanistan.

On the final day of his visits to Qatar, Bahrain, and Kuwait, Austin thanked the crucial partners responsible for helping to transit 124,000 evacuees from Afghanistan in 17 days. The feat, Austin said, required those partners to surge their capabilities and make quick adjustments so the Defense Department and interagency partners could respond to the humanitarian needs, including providing food, water, shelter, and medical attention to the Americans, endangered Afghans, and third-country nationals flowing through American air bases.

Austin stressed the successful operation while downplaying the havoc witnessed on the tarmac at Hamid Karzai International Airport, where the Taliban provided perimeter protection. But the Defense Secretary also acknowledged the danger of a reconstituted terrorist group under a permissive governance by the Taliban.

“The whole community is kind of watching to see what happens and whether or not Al-Qaida has the ability to regenerate in Afghanistan,” Austin said. “The nature of Al-Qaida and ISIS-K is they will always attempt to find space to grow and regenerate.”

Austin told traveling journalists in Kuwait City that the Taliban had been put “on notice” and that the international community was watching to see how they will act under the scrutiny.

“One of the ways the Taliban can demonstrate that they are serious about being a bona fide government and respected in an international community is to not allow that to happen,” he said.

Austin said the United States would retain an “over-the-horizon” counterterrorism capability in the region, understood to be the ability to fly intelligence, surveillance, and reconnaissance missions as well as conduct armed strikes from the very Gulf bases he visited this week.

He did not describe any new capabilities closer to Afghanistan. Currently, drones must commute four hours each way from Al Udeid Air Base in Qatar to reach Afghanistan, giving them little time to hover over the country.

Austin declined to describe the nature of over-the-horizon basing relationships with the Gulf countries, saying it was not part of his discussions.

“We’ve maintained capability in the region,” he assured. “We maintain capability from other places. We have the ability to do a heck of a lot more now from greater distances than we could 20 years ago.”

With the Taliban announcing a new interim government of hardline loyalists in recent days, Austin was questioned on his assessment of Afghanistan.

“The landscape has changed a bit with the Taliban taking over,” he said. “We’ll continue to watch and make sure that we remain vigilant on any type of capability that’s being developed in the region that can export terror to the homeland.”  

Austin said Al-Qaida and ISIS-K will seek ungoverned spaces where they can grow but that the Taliban will be cut off from international recognition and the resources it needs to govern if it harbors terrorist groups.

“If they demonstrate that they’re going to harbor terrorism in Afghanistan, all of that will be very, very difficult for them to achieve,” Austin said.

“It’s the Taliban’s government. We don’t get a vote in that,” the Secretary said when asked about the government composition of Haqqani network fighters who have targeted American Soldiers in the past. “These are people that I don’t look favorably upon personally. But again, it’s the Taliban’s government.”

While in the Gulf, Austin visited American interagency personnel at Naval Support Activity Bahrain, members of the 24th Marine Expeditionary Unit, and the Special Purpose Marine Air-Ground Task Force, Crisis Response in Kuwait who helped with the evacuation in Kabul and were present during the ISIS-K terrorist attack.

Those units were more concerned with how their comrades were doing back at Walter Reed National Military Medical Center, Austin said.

“The first question from them is, ‘How is so and so doing?’ and they’re talking to them on a daily basis, cell phone, and that sort of stuff,” Austin said.

“When I visited the Marines in the hospital, half of them were starting to do push-ups even though they were injured. They were still trying to do P.T. in the hospital. But that’s to be expected with these young warriors,” Austin added. “They always go above and beyond the call.”

Second Inspector General Review Identifies Disparities Facing More Minorities, Women

Second Inspector General Review Identifies Disparities Facing More Minorities, Women

Less than 10 months after the Air Force Inspector General released an Independent Racial Disparity Review detailing numerous disparities facing Black Airmen, a second review recorded still more disparities facing other racial and ethnic minorities, as well as women, in the Air and Space Forces.

Released Sept. 9, the 208-page report details disparities in recruitment, retention, and promotions among women, Asian Americans, Native Americans, Latinos, and Pacific Islanders when compared to white men. On top of that, one in every three female service members said they had experienced sexual harassment during their careers.

The report “basically points out very clearly, and I think very convincingly, that there are a lot of disparities within the Air Force, in a number of facets of the Air Force experience,” Air Force Secretary Frank Kendall told reporters in a briefing.

While not every racial and ethnic minority faces the same disparities across all areas, a common theme in the report was a lack of minorities and women in leadership roles. In particular, those groups are especially underrepresented in the operations field.

“Our operations people reflect on an enormous amount of disparity,” Kendall said. “And being part of that segment of the Air Force has a lot to do with all the other aspects of how your career works out. And we definitely need to address that.”

Just as the initial Independent Racial Disparity Review found that Black Airmen and Guardians were underrepresented in promotions to the ranks of E-5 through E-7 and O-4 through O-6, the second study found that:

  • Latinos are underrepresented in promotion to E-5, E-6, E-9, and O-4 through O-6
  • Asian Americans are underrepresented from E-7 through E-9 and O-4 through O-6
  • Native Americans are underrepresented from E-5 through E-8 and O-4 through O-6
  • Pacific Islanders are underrepresented in E-5, E-8, and E-9.

The operations field is the least diverse specialty code in terms of race, ethnicity, gender. And within that career field, the pilot speciality is the least diverse of them all. Just 14 percent of Air Force pilots are racial or ethnic minorities, with no one racial or ethnic minority overrepresented in the field. Women make up just 7.7 percent of pilots, despite making up more than 20 percent of officers and of the overall force.

That specific disparity carries an added impact, said Lt. Gen. Sami D. Said, the Air Force’s Inspector General.

“If you’re a pilot, you have a much better chance of reaching higher ranks, getting command opportunities,” Said said. “There’s a lot of our organizations [that] are by nature operational, so you have more opportunities to compete for them, so it makes you more competitive to get promoted. So it builds on itself.”

Indeed, the report found that all racial and ethnic minorities besides those who identify as multi-racial were underrepresented as wing commanders and as general officers—more than 90 percent of Active-duty Air Force, Air Force Reserve, and Air National Guard general officers are white.

Besides promotion, there were other disparities noted. Latino service members were 33 percent more likely to have been subjects of Air Force criminal investigations. Native Americans, based off Rates Per Thousand analysis, were more likely to face court martial, be administratively discharged, or to separate prior to 10 years of service, though Said did caution that because Native Americans make up the smallest minority in the service, sample sizes were especially small and it can be hard to draw any “convincing conclusions” from the data.

However, the report did note there appeared to be less of a disparity among all minority groups when it came to disciplinary action.

Asian Americans, meanwhile, were significantly underrepresented in both enlisted and officer accessions, highlighting a larger issue, Said said.

“The answer is absolutely yes,” said Said when asked if the department has an issue recruiting a diverse force. “The problem starts with accessions. And that’s where the ball starts rolling, where we start building disparity. Because if you’re not gaining a percentage of the population that’s reflective of the broader population, you start with the problem.”

There are also issues, Said said, with perception. The first review found that many Black Airmen do not trust the chain of command to handle instances of racial discrimination nor believe they will be given the same opportunities or the benefit of the doubt. The second review found similar sentiments among other ethnic and racial minorities, though to a lesser extent.

Many women, meanwhile, expressed skepticism at the idea that they receive equal treatment to their male counterparts. Nearly half of female Airmen and Guardians surveyed said they “face challenges or barriers that constrain their ability to perform their duties, which male peers do not face” and that “maintaining work/life balance and taking care of family commitments adversely impacts” their careers more than men’s. On top of that, 45 percent said they have to work harder at their job than men to prove their competence. 

More than a quarter of female troops also said they have experienced sex-based discrimination, with a third saying they have witnessed or experienced sexual harassment. Female officers reported the highest rates in response to both questions.

Said and Kendall both noted that the report merely serves to record disparities, not identify or address the root causes of them. In contrast, a second report also released Sept. 9 as a follow-up to the Independent Racial Disparity Review recorded the Air Force’s progress in addressing the issues facing Black Airmen identified in the initial review.

“It essentially assembles a report on the actions that have been taken in response to that report. And the bottom line there for me is that we have made some progress, but we still have a lot of work to do,” said Kendall.

The initial review identified 16 disparities that the service is now working to address through root-cause analysis and implementing meaningful change. But the executive summary of the follow-up report notes that “it is unreasonable to expect to see substantive results in six months.”

Still, because that first review is further along in the process than the broader second one, Said said, there is an opportunity to speed up the process. Already, he said, leaders have noted similarities in the findings of the two reviews.

“A common theme … in the words of the Guardians and Airmen, is a lack of people that look like us, that can mentor us and advise us,” Said said. “There are many areas of overlap between the two, and we picked up on those … It’s going to make ongoing cause analysis applicable to this effort, rather than start from scratch.”
