Navy could get by with more Super Hornets until a better design came along. Still in production for the RAAF, IIRC. Heck, so could the USAF and USMC. Only thing left in the cold would be a replacement for the Harriers.
OK, looking at the specs, the F-35A, USAF variant is almost as capable as the Super Hornet. The F-35B&C would be even less capable. Oh, and the Super Hornet costs half as much as the F-35.
1. Axe the F-35
2. Buy Super Hornets to replace thrashed AF/Navy/USMC systems until a better stealthy alternative is found. (Maybe a F-22 beefed up for carrier duty.)
3. A-10-ish STOL that could use something like a ski-jump on the amphibious assault ships for USMC CAS.
