It really depends on the nature of the fight. If we go against a near-peer adversary, and the Navy has to stay, well, let’s call it a reasonable distance from their shoreline, then range becomes critical.
Further, in such a conflict, that adversary will kill any big wing/USAF tanker that comes close, so…all of the super hornets will need to be tanked by other super hornets from the carrier.
Not an ideal situation.
The F-35, for all its faults, has some pretty good range. The Navy version in particular has more range then either the Marine Corps or Air Force version.
In a counterinsurgency, where there are ample Air Force tankers overhead, the Super Hornet is great…but long range is really needed for some scenarios…
Let me add that in that high end fight, in that near peer scenario, stealth will be a requirement for the early stages of conflict if we want those airplanes to survive.
