The US Air Force is in no hurry to commit to a next-gen fighter design

By: Sebastian Sprenger

BERLIN — The U.S. Air Force is taking its time to settle on a next-generation fighter design, awaiting instead lessons learned from the F-35 jet and playing the field with promising technologies, according to a senior service official.

Options being kicked around are still in the conceptual stage, as America's newest fighter, the fifth-generation F-35, is only now “coming off the line,” according to Lt. Gen. David Nahom, the Air Force's deputy chief of staff for plans and programs.

“We're not in a hurry,” Nahom told Defense News on the sidelines of the International Fighter Conference, an air power-themed confab of industry and government officials held in Berlin, Germany. He noted that expected deliveries of the F-35 and the relatively young age of the F-22 fleet enables the service to be picky about moving forward with the envisioned Next Generation Air Dominance weapon.

In short, the Air Force wants to keep its options open for as long as possible for a weapon whose combat punch will lie not in a single aircraft but rather in the amalgamation of hardware and software, an airborne concerto of data clouds, artificial intelligence, and boundless interconnectivity.

“We don't want to get too stuck into a platform,” Nahom said. “It's a very different way to approach it.”

Still, the service plans to lay the groundwork for boosting the domain of information and data — organizing it, analyzing it, sharing it — as a key element for future aerial warfare. To that end, officials will include a “significant investment in the digital backbone” in the next budget request, Nahom said.

As the Air Force studies its options, service analysts have shied away from the term “sixth-generation” aircraft as a successor to the F-35 because it's unclear what breakthrough technology will be created next. “What are the characteristics of sixth-generation? I don't know,” Nahom said.

“Stealth is important,” he added, referring to one of the advertised features of the F-35. “But speed is important, too.”

The service aims to develop a new capability quickly once the theoretical legwork is done. That is why there is a renewed emphasis now on engineering processes and algorithm development that Nahom said will have to unfold much faster than under previous aircraft programs.

Air Force acquisition chief Will Roper has put down a marker to develop an aircraft within five years. “Based on what industry thinks they can do and what my team will tell me, we will need to set a cadence of how fast we think we build a new airplane from scratch. Right now, my estimate is five years. I may be wrong,” he told Defense News in an interview in September.

The service's information-heavy tack on future aerial warfare echoes two European projects aimed at building a next-generation weapon: the British-led Tempest and the Franco-German-Spanish Future Combat Air System. Both programs also lean on the the premise that data clouds, driven by artificial intelligence, can turn flying pieces of metal into breakthrough weaponry.

In the case of the continental program, an envisioned “combat cloud” will be “the ocean between the islands of the platforms,” French Maj. Gen. Jean-Pascal Breton said at the conference.

But Nahom noted a difference in the American way of thinking when it comes to piercing contested airspace — a key skill required of all future warplanes. While the Europeans seem to perceive the task as popping dispersed bubbles of ever-improving air defense systems, the U.S. view is that any airspace may be contested at any given time.

That means a next-generation aircraft will be constantly engaged in the mission of punching its way through enemy defenses, like finding the holes in a never-ending series of Swiss cheese, Nahom said.

    What to expect from AI, space and other tech over the next 18 months

    By: Aaron Mehta What will the next 18 months mean for the Pentagon's ongoing challenge to maintain a technological edge over its enemies? That was the question posed to a panel of experts at the 17th annual C4ISRNET conference Thursday. And the answers underline just how wide the technical areas of expertise are that Pentagon officials need to get their heads around in the modern era — and how the situation will remain fluid going forward. For Richard Linderman, deputy director for research and engineering in the Office of the Assistant Secretary of Defense, the focus is on manufacturing the vital microelectronics that provide the base for all of America's high-end technologies. He predicts a push to create those chips at a higher rate domestically, which in turn would allow greater trust that the chips, forming the basis of communications equipment or artificial intelligence, would not be messed with by a foreign entity. Concern about the domestic production of microelectronics is expected to be part of a large defense industrial base review now underway. “If you're right out on the pointy end of the spear, you might not want chips made in China to be the foundation of your communications gear,” Linderman told the audience. “So I think you're going to see those kinds of investments increase dramatically, and it will be an exciting prospect for us to bring new dimensions to this discussion of trusted, assured microelectronics.” James Hasik, a professor at the National Defense University, said he would be keeping a close eye on how the autonomous Sea Hunter vehicle does during ongoing testing. DARPA recently transferred the Sea Hunter, designed to travel thousands of miles over open seas, for months at a time, without a crew member on board, over to the Navy for continued testing. “The economics of that concept are so compelling,” Lungu said. If the concept proves out, it could have “some profound applications for fleet structure, some profound applications for warfighting.” Clark Groves, a space expert also at NDU, predicted that the long-awaited boom in small satellites will finally reach critical mass in the near-future, driven by the desire to move the massive telecommunications market onto cheaper systems. DoD stands to benefit, as this would be happening at the same time the Pentagon seeks to move from relying on massive, expensive aggregated systems towards a disaggregated model relying on multiple cheap, smaller systems — which present more of a challenge for any enemy nation that may seek to take out American assets in space. “Once small satellites begin being produced in large numbers, that will fundamentally alter the industrial base of the status quo, and that will also affect the launch base,” Groves said, which in turn “will give opportunities to DoD for more effective per-cost basis to exploit the architecture that we need for resilience.” Finally, Ed Brindley, acting deputy chief information officer for cybersecurity at the Pentagon, pointed to a “more determined focus” inside the Pentagon to shift how it handles artificial intelligence. At the core of that, he said, is the upcoming AI Center of Excellence, which Deputy Secretary of Defense Patrick Shanahan predicted will be up and running in the next six months. “Part of what we will see will be opportunities for us to adopt some of what is occurring within industry today,” Brindley said, noting that AI isn't just for warfighting but could have massive impacts on the internal processes of the Pentagon, including in the medical and legal professions. https://www.c4isrnet.com/show-reporter/c4isrnet-conference/2018/05/10/what-to-expect-from-ai-space-and-other-tech-areas-over-the-next-18-months/

    Artificial intelligence systems need ‘checks and balances’ throughout development

    Andrew Eversden The Pentagon's primary artificial intelligence hub is already studying how to aim a laser at the correct spot on an enemy vehicle, pinpointing which area to target to inflict the most damage, and identifying the most important messages headed to commanders, officials said June 16. But as part of that work, the Department of Defense needs to carefully implement checks and balances into the development process, experts urged June 16. “Fundamentally I would say there's a requirement ... that there's going to be a mixture of measures taken to ensure the governability of the system from the first stage of the design of the system all the way up through the operations of the system in a combat scenario,” said Greg Allen, the Joint Artificial Intelligence Center's chief of strategy and communications at the Joint Artificial Intelligence Center, at the Defense One Tech Summit June 16. The JAIC is working on several lethality projects through its new joint warfighting initiative, boosted by a new contract award to Booz Allen potentially worth $800 million. “With this new contract vehicle, we have the potential to do even more this next year than we did in the past,” Allen said. Meanwhile, the Army's Artificial Intelligence Task Force is working on an advanced threat recognition project. DARPA is exploring complementing AI systems that would identify available combat support assets and quickly plan their route to the area. Throughout all of the development work, experts from the military and from academia stressed that human involvement and experimentation was critical to ensuring that artificial intelligence assets are trustworthy. The department has released a document of five artificial intelligence ethical principles, but the challenge remains implementing those principles into projects across a department with disparate services working on separate artificial intelligence projects. “We want safe, reliable and robust systems deployed to our warfighters,” said Heather Roff, senior research analyst at the Johns Hopkins Applied Physics Lab. “We want to be able to trust those systems. We want to have some sort of measure of predictability even if those systems act unpredictably.” Brig. Gen. Matt Easley, director of the artificial intelligence task force at Army Futures Command, said the service is grappling with those exact challenges, trying to understand how the service can insert “checks and balances” as it trains systems and soldiers. Easley added that the unmanned systems under development by the Army will have to be adaptable to different environments, such as an urban or desert scenarios. In order to ensure that the systems and soldiers are ready for those scenarios, the Army has to complete a series of tests, just like the autonomous vehicle industry. “We don't think these systems are going to be 100 percent capable right out of the box,” Easley said on the webinar. “If you look at a lot of the evolution of the self-driving cars throughout our society today, they're doing a lot of experimentation. They're doing lots of testing, lots of learning every day. We in the Army have to learn how to go from doing one to two to three vehicle experiments to have many experiments going on every day across all our camp posts and stations.” Increasingly autonomous systems also mean that there needs to a cultural shift in among all levels of military personnel who will need to better understand how artificial intelligence is used. Roff said that operators, commanders and judge advocate generals will need to better understand how systems are supposed “to ensure that the human responsibility and governability is there.” “We need to make sure that we have training, tactics, procedures, as well as policies, ensuring where we know the human decision maker is,” Roff said. https://www.c4isrnet.com/it-networks/2020/06/18/artificial-intelligence-systems-need-checks-and-balances-throughout-development/
