The concept involves installing the F-35 computing architecture and certain hardware in the F-22. Even Lockheed acknowledges the idea would require "significant initial investment", but could yield "some cost savings" in the long-term. Discussions with the US Air Force are underway.
"Say, if we want to add something to [the F-22] CNI suite, F-35 could take that wholesale with minimal modifications," says Jeff Babione, vice-president and deputy general manager of the F-22 programme. "So you'll see this bouncing back and forth where F-22 develops something for F-35, and F-35 develops something for F-22."
Although less powerful and slower than the F-22, the F-35 has more sensors. Installing the electro-optical targeting system, infrared search and track and distributed aperture system "as is" on the F-22 is impossible, the company says, but the proposed "common architecture and common modules provides the opportunity for synergy ... at a potentially lower cost across both platforms".
