NEW DELHI - India is set to give final approval to a US$2.6 billion deal for military helicopters from US defense firm Lockheed Martin ahead of a visit by US President Donald Trump this month, defense and industry sources said.

Prime Minister Narendra Modi’s government is trying to pull out all the stops for Trump’s trip in a bid to reaffirm strategic ties between the two countries, which have been buffeted by sharp differences over trade.

Modi’s cabinet committee on security is expected to clear the purchase of 24 MH-60R Seahawk helicopters for the Indian navy in the next two weeks, a defense official and an industry source said

India’s defense purchases from the United States have reached US$17 billion since 2007 as it has pivoted away from traditional supplier Russia looking to modernize its military.

The clearance came after the Trump administration rolled out a new “Buy American” plan in 2018 that had relaxed restrictions on sales, saying it would bolster the American defense industry and create jobs at home.

“It’s a government-to-government deal, it is close,” said the industry source.

To cut short lengthy negotiations between Lockheed and the Indian government, the helicopters that will be deployed on India’s warships will be bought through the US foreign military sales route, under which the two governments will agree details of the deal.

Trump will visit India Feb 24-25, the White House said on Monday, his first official trip to the country.

Both countries are separately working on a limited trade agreement ahead of the trip, after earlier imposing tit-for-tat tariffs on each other’s imports.

Trump has called India the “tariff king of the world” but the Modi government has been trying to address some of his concerns.

Trade officials have pointed to large-scale US arms purchases, from surveillance planes to Apache and Chinook helicopters, as proof of India’s willingness to tighten strategic ties.

On Monday, the US State Department said it had approved an Indian request for an Integrated Air Defense Weapon System for an estimated cost of US$1.87 billion, which would further strengthen the two countries’ defense ties.

The two sides are expected to move forward on the deal over the year.

The multirole helicopters from Lockheed will be equipped with Hellfire missiles and torpedoes, and are meant to help the Indian navy track submarines in the Indian Ocean.

Many of India’s warships are without any helicopters because of years of underfunding, and the navy had sought their acquisition as a top priority.

The government outlined only a modest rise in its 2020/21 defense spending to US$73.65 billion in the budget on Feb 1, of which a part will go toward making a down payment on the helicopter purchase, a defense official said.

“We expect a positive announcement soon on the helicopters,” the official said, speaking on condition of anonymity because of service rules. “There are limited resources, but there is an allocation.”

The US State Department approved the sale of the choppers to India last year along with radars, torpedoes and 10 AGM-114 Hellfire missiles.

The clearance came after the Trump administration rolled out a new “Buy American” plan in 2018 that had relaxed restrictions on sales, saying it would bolster the American defense industry and create jobs at home.

The United States has also offered India the armed version of Guardian drones that were originally authorized for sale as unarmed for surveillance purposes, the first such approval for a country outside the NATO alliance.

India plans to buy 30 of these unmanned aircraft for surveillance of the Indian Ocean, at a cost estimated to be about US$2.5 billion, from General Atomics.

However, the defense official said the deal is unlikely immediately because of lack of funds.
