Electromagnetic catapult

The system launches carrier-based aircraft by means of a catapult employing a linear induction motor rather than the conventional steam piston.

Electromagnetic systems also weigh less, are expected to cost less and require less maintenance, and can launch both heavier and lighter aircraft than steam catapults.

They also take up less space below the flight deck and require no fresh water for their operation, thus reducing the need for energy-intensive desalination.

The system was installed on USS Gerald R. Ford aircraft carrier, replacing traditional steam catapults.

With the EMALS, Gerald R. Ford can accomplish 25% more aircraft launches per day than the Nimitz class and requires 25% fewer crew members.

[5] The EMALS uses a linear induction motor (LIM), which uses alternating current (AC) to generate magnetic fields that propel a carriage along a track to launch the aircraft.

[12] Multiple prototypes have been spotted by the media in 2012, and aircraft capable of electromagnetic launching are undergoing testing at a Chinese Navy research facility.

[24] Though, it was initially planned to be imported from foreign firms for INS Vishal, reports as of 2024 suggests, it is being developed indigenously by Bharat Electronics with assistance from private sector companies.
