In a bid to strengthen the Navy's capabilities to detect airborne and surface-based maritime threats, Government has approved the acquisition of five Russian Kamov-31 early warning choppers.
Defence Ministry officials said the Cabinet Committee of Security (CCS) at a meeting on Tuesday gave its approval for procuring these choppers, which can track 30-40 targets on ground and air simultaneously with its airborne electronic warfare radar, mounted on the underbelly of the chopper.
The deal for the five choppers between India and Russia is expected to be signed in the next couple of months, they said.
Navy already has a fleet of nine Ka-31 helicopters, which are deployed on India's only aircraft carrier INS Virat and the Talwar Class Guided Missile frigates of the Navy.
They are also operated from Navy's shore based air stations.
To modernise its air arm, the Navy is on a look out for various types of helicopters including the 10 tonne class multirole helicopters for which global tenders were released last year.
