USAF Sees Five-Year Window To Invent A New Fighter Aircraft Industry
By Steve Trimble and Lee Hudson The U.S. Air Force's vision to rapidly produce multiple fleets of advanced fighters the way Apple makes iPhones begins with an important change in plans for the secretive Next-Generation Air Dominance (NGAD) program. For three years, the Air Force analyzed how to replace the Lockheed Martin F-22 by 2030. The original plan—defined as the Penetrating Counter-Air capability in the Air Superiority Flight Plan released in 2017—called for developing a conventional replacement for the F-22, with a next-generation F-X fighter featuring a dazzling array of new technologies, ranging from adaptive cycle propulsion to advanced weapons and new sensors. As an extended, two-year-long analysis of alternatives neared a conclusion in mid-2018, the Air Force decided to shift to a new approach. The new strategy led Air Force leaders to drain about half of the $13.2 billion budget previously allocated to the NGAD program through fiscal 2024 in the Defense Department's five-year spending plan sent to Congress in March. Instead of launching full development of the F-X within that five-year window, the Air Force is developing a radical new aircraft design process—even as spending continues on deliveries of Lockheed F-35As, Boeing F-15EXs and a host of fighter upgrade programs. “We're at a good point to attempt something new because we have hot production lines for fifth [generation fighters]. [And] fourth-gen fighters [are] going through major multibillion dollar modernizations,” says Will Roper, the assistant secretary of the U.S. Air Force for acquisition, technology and logistics. “So it's a good time to try something new for a five-year window and see if we can create a new way to build airplanes for us that [is] between the building of one or two X-planes and the building of 1,000 units in a major defense acquisition program,” Roper, who is leading the new NGAD strategy, tells Aviation Week in an interview. Roper's comments on the sidelines of Aviation Week's DefenseChain Conference on Oct. 22, help clarify the dramatic shifts within the classified NGAD program over the last year. The U.S. Air Force essentially has delayed F-X development beyond the five-year spending plan to provide a window of time to invent a new business model for the combat aircraft industry, one ideally suited for a new era of air warfare with peer adversaries. The initiative will be supported by the new Program Executive Office for Advanced Aircraft that was established on Oct. 2. The office will be led by Col. Dale White, formerly the senior program director for the Northrop Grumman B-21 bomber development program at the Rapid Capabilities Office. Roper's vision for NGAD calls for a sharp break from the conventional acquisition approach adopted for the B-21, with a single prime contractor responsible for the full aircraft lifecycle, including at least a 10- to 15-year period between an initial contract award and delivering an operational capability. To Roper, the ideal model for NGAD is not another Western fighter program, but rather a consumer electronic device. Apple's customers buy an iPhone model that is designed to become obsolete within a few years, and replace it with a more advanced device, he says. The equivalent in the fighter business are aircraft designed to last perhaps 3,500 flight hours, which the U.S. Air Force buys in batches of hundreds and replaces in intervals of 10 years or less. “We want to retire airplanes when the next one is ready to be brought out—very similar to the iPhone model. So there's no reason to keep that old iPhone once you have the new one,” Roper says. Over the next five years, the Air Force wants to define the digital engineering-based approach to the hardware and common operating system approach to the software for the NGAD aircraft family. The goal is to attract new companies besides traditional defense firms to be involved in production, along with the specialized design units of the prime contractors such as Lockheed's Skunk Works, Boeing's Phantom Works and Northrop Grumman's Scaled Composites. “I could imagine companies that could build a few airplanes per month eventually breaking in and wanting to do it because there's an opportunity to do it frequently. And let's face it, design and cutting-edge airplanes [are] just wicked cool,” Roper says. https://aviationweek.com/defense/usaf-sees-five-year-window-invent-new-fighter-aircraft-industry
