The following is the June 23, 2022 Congressional Research Service In Focus report, Air Force Next-Generation Air Dominance Program.
From the report
According to the Air Force, the Next-Generation Air Dominance (NGAD) program is intended to develop “a portfolio of technologies enabling air superiority.” The Air Force intends for NGAD to replace the F-22 fighter jet beginning in 2030, possibly including a combination of crewed and uncrewed aircraft, with other systems and sensors. NGAD began as a Defense Advanced Research Projects Agency project. Since 2015, Congress has appropriated approximately $4.2 billion for NGAD.
NGAD is a classified aircraft development program, but the Air Force has released a few details. On September 15, 2020, then-U.S. Air Force acquisition executive Dr. Will Roper announced that the Air Force had flown a full-scale flight demonstrator as part of the NGAD program. Secretary of the Air Force Frank Kendall announced on June 1, 2022 that NGAD program technologies have matured enough to allow the program to move to the engineering, manufacture, and design phase of development.
Is the Goal of NGAD a New Fighter?
While a stated aim of the NGAD program is to replace the F-22 fighter jet, the aircraft that come out of the NGAD program may or may not look like a traditional fighter. The Air Force is developing technologies involved in NGAD to provide air dominance. Part of the program’s goal is to determine how to achieve that end, independent of traditional U.S. military approaches to air dominance. NGAD could take the form of a single aircraft and/or a number of complementary systems—manned, unmanned, optionally manned, cyber, electronic—forms that would not resemble the traditional “fighter.”
For example, a larger aircraft the size of a B-21 may not maneuver like a fighter. But that large an aircraft carrying a directed energy weapon, with multiple engines making substantial electrical power for that weapon, could ensure that no enemy flies in a large amount of airspace. That would achieve air dominance. There appears to be little reason to assume that NGAD is going to yield a plane the size that one person sits in, and that goes out and dogfights kinetically, trying to outturn another plane—or that sensors and weapons have to be on the same aircraft.
