If anything, the Hornet opens up:
Coastal anti ship defenses
Naval air bases and ports that ships can dock at
F-18E/F escort tanking and an escort tanking AI task. (Imagine being hit, leaking fuel. Nearest tanker is called, gives you fuel while flying back to base)
Supply and replenishment overhaul so oil tankers and military cargo ships are sent from shore to ship or reverse as supplies are moved.
Different, perhaps localized damage for naval ships. Bonus if this affects airports, like knocked down towers mean no ATC, beacons destroyed, etc.
Carrier based cargo planes
SAM logic that pairs with AGM-88 missiles.
Emergency arresting gear at airports.
Overall, I think the Hornet asks more for a general overhaul more than addition of totally new assets. Though I certainly don't mind!
