Aircraft Carrier Catapults: How Modern Launch Systems Work
Aircraft carrier catapults are among the most critical systems in modern naval aviation. By generating immense force over a short distance, they launch heavily loaded aircraft from a ship’s limited deck space and enable sustained air operations at sea.
From early steam-powered designs to advanced electromagnetic systems, aircraft carrier catapults have transformed how naval aircraft take off. Their development reflects major advances in engineering, aviation, and maritime warfare.
Aircraft carrier catapults launch fixed-wing aircraft from a ship’s short flight deck. They accelerate an aircraft rapidly along a track, allowing it to achieve sufficient speed for takeoff within the limited available distance.
Modern aircraft carrier catapults generally use either steam or electromagnetic power. Steam catapults use pressurized steam to drive pistons, while the Electromagnetic Aircraft Launch System uses electric energy and linear motors for smoother, more controlled acceleration.
A launch bar on the aircraft’s nose landing gear connects to a shuttle beneath the flight deck. When activated, the catapult pulls the aircraft forward while the pilot applies full engine power. The aircraft becomes airborne as the shuttle reaches the end of its stroke.
Aircraft carrier catapults expand the range of aircraft that can operate at sea. They support heavier aircraft, greater fuel loads, and more weapons than ski-jump launches typically permit, although they require complex machinery, maintenance, and highly trained personnel.
