The CWG Committee has offered to transfer the aerostat balloon to us and it is still being considered and we may use it for research purposes, DRDO officials said here.

After the games ended in October last year, the huge balloon has been lying in the Jawahar Lal Nehru stadium unused and organisers have been looking for bidders for it.

Asked if the DRDO would make any payments for the aerostat, he said, "The letter talks about transfer only and has not quoted any price."

The DRDO has developed its own version of aerostat called 'Akashdeep' in its Agra lab for surveillance research, which can keep an eye on a 30-km radius.

The military aerostat system is loaded with sensors for electronic and communication intelligence and allows the forces to carry-out surveillance over a large area.

The indigenous aerostat was showcased for the first time at the Aero India show at Bangalore last month and once fully developed, would be deployed at borders and near vital assets and points for warning against any aerial threat
