India Navy is going to launch second indigenous aircraft carrier (IAC-II) - INS Vishal, using US based advanced catapult-based aircraft launch mechanisms.
It will have to choose between catapult-based aircraft launch mechanism (CATOBAR) and electro-magnetic aircraft launch system (EMALS).
CATOBAR is powered by a steam catapult and EMALS uses an electric motor-driven catapult instead.
The use of electro-magnetic energy allows the launch of much heavier aircraft and also reduces the stress on the aircraft.
INS Vishal, nuclear-powered vessel is a follow up of INS Vikrant class of aircraft carriers.
India’s first domestic carrier, Vikrant, weighing 40,000 tonnes, is scheduled to be launched by 2018-end.
It works on a Short Take-Off But Arrested Recovery (STOBAR) mechanism similar to that in the present carrier INS Vikramaditya.
