Anyone attempting to do an amphibious landing, where they are concerned about air superiority, are idiots.
You have / seize air superiority, you bomb the enemy round the clock, you remove mines and obstacles, then you conduct your amphibious operation. That’s how it works for non-idiots. Part of a larger system.
What the marines then need, and what 076 provides, is organic close-in (nearby) air support for striking ground targets, possibly helicopters and drones as well.
The USMC is part of the Department of the Navy and so is their budget. Marine Corps F/A-18s, F-35B/Cs (yes they operate CATOBAR jets off CVNs), A/V-8Bs, and helicopters all fly from US Navy ships. The marines all disembark from USN ships too (or aux fleet).
