by M/s Embraer for which the contract was signed in
2008. The next aircraft is expected to arrive in
December 2012.
22. Future Development
•DRDO and the Bengaluru-based Centre for Air Borne
Systems (CABS) launched a new project to build larger and
more capable AWACS.
•Initially, two AWACS aircraft were to be developed, with
four more to follow at a later stage.
•Clearances for the project were received from the government
in January 2013,and in March 2015 a decision was made to
purchase two Airbus A330s which was expanded to six planes
in February 2017 the planes will also double as aerial refuelers
