Applications in an aircraft carrier include [25] weapons elevators, aircraft elevators, hangar doors, rudder mechanisms, and propulsion systems. Propulsion systems were discussed in the previous section. The weapons elevators have a load capacity of 42,000 pounds and must move at 2 feet per second even when the sea is rough.

A carrier-based aircraft (also known as carrier-capable aircraft or carrier-borne aircraft) is a naval aircraft designed for operations from aircraft carriers. Carrier-based aircraft must be able to launch in a short distance and be sturdy enough to withstand the abrupt forces of launching from and recovering on a pitching deck.
