MOSCOW, September 16. /TASS/. Russia has started developing an electromagnetic catapult for new-generation aircraft carriers, a defense industry source told TASS on Wednesday.

"The electromagnetic catapult development is under way, and a mockup has been made," the source said.

According to the source, the prototype of the advanced catapult has been brought to the Central Aerohydrodynamic Institute. The catapult needs no big steam boilers and is powered by a battery.

As is known, the United States is working on an electromagnetic catapult too. The Electromagnetic Aircraft Launch System (EMALS) is essentially a linear induction motor with a number of coils generating a travelling magnetic field. The magnetic field accelerates the object. The EMALS has a 100,000-hp (73.5MW) motor affording the catapult-launched manned and unmanned aircraft a takeoff speed of 333 km/h. Electromagnetic technologies offer a sizeable reduction in the catapult’s maintenance cost, an increase in its reliability and effectiveness, much higher launch power and more accurate control of the aircraft’s final acceleration speed during takeoff. In addition, the electromagnetic catapult allows smoother acceleration and less stress on the aircraft.

The EMALS is designed to equip advanced heavy nuclear-powered aircraft carriers in the CVN-79 Gerald R. Ford class.
