21. • The arrival of this aircraft marks the beginning of
another phase of journey leading to the next major
milestone of integration of the DRDO developed
mission system, which will be followed by
development flight trials in India beginning of 2013.
• It may be noted that this is the first aircraft delivered
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
