So, an amphibious assault ship is somehow the size of a ULCC. Odd....
Built to support amphibious landings, the Revolution class can also work quite well during peacetime by acting as a barge carrier. And just in case it finds itself alone and without support, it also has six [REDACTED] guns mounted in two turrets.


So I messed around and decided to make the process of sailing this ship a bit more complicated

Activation groups 1 to 4: Starts/stops engines 1,2,3,4
Activation groups 5 to 8: Locks/unlocks propeller pitch control for engines 1,2,3,4
Trim slider: Control rudder. Up=turn to starboard. Down=turn to port
VTOL slider: Controls propeller pitch. Up=forward Down=reverse. Works best when the VTOL slider is around 1/3 up/down

Sail at 10% thrust when not turning. Increase thrust when turning to maintain speed.
