CATOBAR
CATOBAR
(Catapult Assisted Take-Off But Arrested Recovery or Catapult Assisted Take-Off Barrier Arrested Recovery) is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier. Under this technique, aircraft launch using a catapult-assisted take-off and land on the ship (the recovery phase) using arrestor wires. Although this system is costlier than alternative methods, it provides greater flexibility in carrier operations, since it imposes less onerous design elements on fixed wing aircraft than alternative methods of launch and recovery such as STOVL
STOVL
or STOBAR, allowing for a greater payload for more ordnance and/or fuel. CATOBAR
CATOBAR
can launch aircraft that lack a high thrust to weight ratio, including heavier non-fighter aircraft such as the E-2 Hawkeye
E-2 Hawkeye
and Grumman C-2 Greyhound.[1][2][3]

carriers is the steam catapult. Its primary advantage is the amount of power and control it can provide. During World War II the US Navy used a hydraulic catapult. The United States
United States
Navy is developing a system to launch carrier-based aircraft from catapults using a linear motor drive instead of steam, called the EMALS. Current Users[edit] Only two countries currently operate carriers that use the CATOBAR system following the decommissioning of Brazil's NAe São Paulo in February 2017; the U.S. Nimitz-class, U.S. Gerald R. Ford-class and France's Charles De Gaulle. US Navy Gerald R. Ford-class carriers will use the EMALS electromagnetic aircraft launch system in place of steam catapults.[4] Active CATOBAR

Potential Users[edit] The Chinese Type 002 aircraft carrier, currently under construction at the Jiangnan Shipyard, will feature an integrated electric propulsion system that will allow the operation of electromagnetic launch catapults, similar to the Electromagnetic Aircraft Launch System (EMALS) used by the United States
United States
Navy.[5][6] INS Vishal, India's second indigenous aircraft carrier of the Vikrant-class, is planned to be of 65,000 ton displacement and to utilize the EMALS
