On board the aircraft carriers there are typically 70-80 planes for defence, attack, refuelling in flight, jamming enemy communications and radars, and for airborne surveillance and control.
In fact, SLCMs permit virtually every combatant ship in the inventory to enjoy a crucial capability which once resided exclusively in the relatively small number of aircraft carriers: the ability to defend itself and to project naval power over great ranges by holding at risk enemy shipping and targets ashore.
