'By the time this aircraft comes, and by the time the Indian Navy gets used to it from initial shore-based operations, plans for two more aircraft carriers could be amended to house this system.'

There have been no tenders of RfPs yet for the Hawkeye E-2D, but then companies from worldwide present their wares to various countries either by themselves and at their own cost, or make offerings in response to Request for Information (RfI) which are floated in routine by all the armed forces to know what is available in terms of newer generation of systems.

Future aircraft carriers of the Indian Navy would also have to be equipped with catapult launching systems, for which it is already looking around. India's second and third aircraft carriers should have this facility along with lifts and adequate open area for what is called free deck takeoff.

The Mig 29Ks that the Indian Navy is buying for Gorshkov, will be launched by a ski ramp.

Tip to tip, the Hawkeye is a bigger aircraft than the Mig 29.

Trudell said that although Northrop Grumman had been allowed to make presentations to the Indian Navy, its sale would have to be direct between the Indian and US government under the Foreign Military Sales (FMS) programme. There are many systems on board, developed for US Navy, which only the US government can clear for transfer to other countries.

The US Navy has initially ordered five Hawkeye E-2Ds under a Low Rate Initial Production (LRIP) programme, and the first aircraft should be delivered to the US Navy in 2011.

India can get the aircraft within three years of a contract being signed, said

Trudell.
