The Electromagnetic Aircraft Launch System (EMALS) is a type of electromagnetic catapult system developed by General Atomics for the United States Navy. The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston , providing greater precision and faster recharge ...
The catapult operator then pushes a button to fire the catapult. Once the catapult fires, the hold-back breaks free as the shuttle moves rapidly forward, dragging the aircraft by the launch bar. The aircraft accelerates from zero (relative to the carrier deck) to about 150 knots (280 km/h; 170 mph) in about 2 seconds.
The systems commands replaced the Navy bureau system in 1966 and report to the Assistant Secretary of the Navy for Research, Development and Acquisition. [1] The current Navy systems commands are: Naval Sea Systems Command (NAVSEA) Naval Air Systems Command (NAVAIR) Naval Information Warfare Systems Command (NAVWAR) (formerly SPAWAR),
Based on its experiences with the launching of short-range theater missiles by Iraq during the 1991 Persian Gulf War, the U.S. Department of Defense (DoD) concluded that expanded theater missile warning capabilities were needed, and it began planning for an improved infrared satellite sensor capability that would support both long-range strategic and short-range theater ballistic missile ...
The use of catapults allows an aircraft carrier to launch large fixed-wing aircraft. For example, the U.S. Navy launches its E-2 Hawkeye AEW aircraft and C-2A Greyhound cargo aircraft with catapults. An F-35B utilizes a ski-jump to become airborne off the deck of HMS Queen Elizabeth
The catapult used on aircraft carriers consists of a track or slot built into the flight deck, below which is a large piston or shuttle that is attached through the track to the nose gear of the aircraft, or in some cases a wire rope, called a catapult bridle, is attached to the aircraft and the catapult shuttle.
The Department of the Navy has shown no desire to scale back or cancel the program. On 24 March 2006 the Navy exercised its three-year, $3 billion option to extend the contract through September 2010. [1] In April 2006, users began to log on with Common Access Cards (CACs), a smartcard-based logon system called the Cryptographic Log On (CLO ...

CATOBAR (catapult-assisted take-off but arrested recovery [1] or catapult-assisted take-off barrier arrested recovery [2]) is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier.
