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 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 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),
In 2010, the SBIR program across 11 federal agencies provided over $2 Billion in grants and contracts to small U.S. businesses for research in innovation leading to commercialization. As of February 2018, SBIR programs are in place at the following agencies: [5] Department of Agriculture (National Institute of Food and Agriculture) [6]
The United States Navy is developing the use of a linear motor-based electromagnetic catapult system called the Electromagnetic Aircraft Launch System (EMALS) with the construction of the Gerald R. Ford-class aircraft carriers, and a similar system has also been developed for the Chinese People's Liberation Army Navy's Type 003 aircraft carrier.
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 Hawker Sea Hurricane W9182 on the catapult of a CAM ship. CAM ships were World War II–era British merchant ships used in convoys as an emergency stop-gap until sufficient escort carriers became available. CAM ship is an acronym for catapult aircraft merchant ship. [1]
