New Delhi. In a boost to Naval air arm, India is set to go ahead with a $3.1 billion deal with the US to acquire ten Boeing P-8I patrol aircraft with the Navy already having 12 such aircraft that will add to its surveillance capabilities in the Indian Ocean Region.

The procurement of these Boeing P-8I maritime patrol aircraft is likely to be cleared at a key meeting of the Defence Acquisition Committee (DAC) chaired by Defence Minister Rajnath Singh expected to meet next week, with the contract to be processed under the foreign military sales (FMS) route.

The deal, which will include a mandatory clause for at least 30% offsets to domestic companies, will add to the 12 P-8I aircraft that have already been ordered by India and will help maintain strong vigil over a region that has seen increasing deployments by the Chinese Navy.

The maritime patrol aircraft, which specialises in tracking and hunting down enemy submarines with lightweight torpedoes and depth charges, are also operated by the US and Australian navies, which operate in coordination with India to keep track of ship movements.

Sources said that the Navy is keen to build up a fleet of 22 of these aircraft at the earliest and the contract will ensure a continuous supply over the next four years as older maritime reconnaissance assets (Russian origin) retire. The first batch of eight aircraft were ordered under a $2.1 billion deal in 2009 and a follow on order for four was placed in 2016.

The P-8I aircraft have been a pride of place for the Indian Navy that is depending on the fleet for a variety of operations — from submarine tracking to search and rescue and even reconnaissance over land.
