The Navy needs a new fighter. Or so they say. See this about the FA-XX.
The Dew Line must be there too.
This will probably become more of a discussion when the gold-plated disaster known as the F-35C fails.
A tip for whomever uses the "6th-generation" label: don't do it. It implies (and it seems justified from the do everything hype...including a possible buddy-tanker mission) that it will come with a "6th-generation" price.
Ask the USAF about "5th-generation" success. They spent over $100B to get 120 combat-coded F-22s and an F-35 program that has been run into the ditch.
Meanwhile, back at the ranch, take a look at a newer version of the Super Hornet flip-book. The big difference is everything here generally works. The polar opposite of the F-35. Since both the Super and F-35 are not anti-access jets, what we have is a significant superiority of the Super Hornet Block II over any version of the F-35 in all areas of true value.
