The USMC is set up to do that. There are seven Wasp-class amphibious assault ships. Each is a Marine ground-air task force in a can.[1] The concept is that the ships stand offshore and launch VTOL aircraft (F-35s and Harriers) from the top, and landing craft from the well deck.
This works great unless the onshore enemy has anti-ship missiles and drones.[2] Unlike fleet carriers, which can stand off from an enemy shore, amphibious assault ships have to operate in sight of shore, maybe a few kilometers, because their job is to launch boats. That's within small drone range.
The assault ships can be much farther offshore for air operations. The flight deck isn’t just for STOVL jets, it can also handle lots of helicopter and tiltrotor traffic, which is also used for ship-to-shore movement.
Also, anti ship missiles and drones aren’t a cheat code. They can be suppressed, jammed, destroyed with preparatory fires, or shot down in flight. Anti-ship missiles aren’t new, nor are anti-anti-ship-missile-missiles. Anti-ship missiles were a major factor in the 1982 Falklands War but not, in the end, a decisive one.
