F/A-XX and the US aircraft industrial base

What might determine the F/A-XX designation and which company builds it?

No designation or contractor is settled here; competing predictions depend on design ancestry, carrier requirements, existing production, and industrial policy.

In March 2025, both the F/A-XX designation and its eventual contractor remained unresolved in this exchange. One hypothesis links Boeing's F-47 to a design originally intended for the Navy, while another expects F/A-XX to remain a distinct aircraft. Reusing a Boeing design might offer economies of scale, but modifying a land-based aircraft for carrier use could require substantial work. A naval design adopted for both services would present a different engineering problem. Competing assessments weigh Northrop Grumman's naval experience, existing F-35, B-21, and F-47 production, and the value of retaining several advanced-aircraft manufacturers. Bomber and fighter factories are not interchangeable, and their locations create congressional employment incentives. These considerations support different contractor predictions, without establishing either design ancestry or a future contract outcome.
