Alpha Design Technologies, Bangalore, and Data Patterns India, Chennai, have been chosen to commercialise a set of three flight critical products of the DRDO.

IFF (identify friend or foe) is carried on all commercial and military flights to make out if a nearby aircraft is friendly or hostile.

The indigenous suite has been developed by Bangalore-based Defence lab, the Centre for Air-Borne Systems.

Launching the suite on Wednesday, Dr V.K.Saraswat, Scientific Adviser to the Defence Minister and Director-General, DRDO, said the Indian IFF was a modern Mk 12 version. It was a by-product of CABS's Airborne Early Warning & Control System. It would be mounted on land systems, systems, fighter and civil planes, aerostats, unmanned air vehicles and medium and long range surface to air missiles.

The suite of an interrogator, transponder and their combine cost the developers around Rs 1.8 crore and would cost less than imported suites.

The Director of CABS, Dr S. Christopher, said in the coming years, the Army, Navy and the Air Force would require several thousand IFF units besides civil aircraft.

Mr S. Rangarajan, CEO of Data Patterns, and Col. Shankar of Alpha Design Technologies were present. The two companies will bid for upcoming orders.
