I think the F-35 will be substantially cut back. We may see a major rebuild program for the AV-8B Harrier II and the USAF may get upgraded F-16’s (essentially using the radar from the F-35A and a derivative of the F-35A’s engine).
The Marines must have the F-35 or they are out of the fixed wing strike business. The USAF is getting theirs now, the question will be ‘how many’. That leaves the Navy — which could very well back out in favor of a new aircraft to fill the strike roll, keeping their Super Hornets for fleet interceptors.
