Washington: India is expected to choose `s S-70B Sea Hawk helicopters at a 16-aircraft tender worth over $1 billion, according to two sources familiar with the matter.
The decision could come during a high-profile visit to the United States by Prime Minister Narendra Modi that starts on Friday.
The Sikorsky deal would be one of several large US arms purchases by India that are nearing completion, including over $2.5 billion in orders for Boeing Co`s AH-64D Apache and CH-47 Chinook helicopters.
Sikorsky Aircraft, a unit of United Technologies Sikorsky AircraftCorp, declined comment on the potential helicopter order.
Those deals could in turn lay the groundwork for a much larger order of 123 helicopters for the Indian Navy, said one of the sources, who was not authorized to speak publicly.
Boeing continues to negotiate with India on the Apache and Chinook helicopters and hopes to have signed contracts by the end of the year, said spokeswoman Caroline Hutcheson.
US weapons makers, keen to offset declining US and European military spending, are watching closely to see whether Modi delivers on his promises to expand India`s strategic relationship with the United States.
India was the top foreign buyer of US arms last year, according to defense research firm IHS Janes, and the two governments are now negotiating a series of specific defense collaboration projects that would involve more co-production.
US industry executives are excited about possible opportunities in India but caution that such deals often take longer to negotiate than expected.
Boeing already has a huge presence in India due to its sales of P-8 maritime surveillance planes and C-17 transport planes. Modi is slated to meet with Boeing Chief Executive Jim McNerney during his US visit.
Boeing is due to deliver a sixth P-8I plane to India later this year, and two more next year. India may also exercise options for four additional P-8 aircraft next year, Boeing officials said.
The US unit of Britain`s BAE Systems is also ready for talks with India about the possible sale of up to 145 of its M777 towed 155mm howitzer artillery pieces, a deal valued at up to $885 million.
Rahul Madhavan, senior manager for aerospace and defense at the US-India Business Council lobby group, said the Modi government appeared to be embracing the Defense Trade and Technology Initiative (DTTI), which aims to increase collaboration on 17 specific defense projects.
"The Indian administration is taking this DTTI initiative forward and it is no longer perceived as just being a US centered type of affair, or a one-way street," he said. "The win-win situation is now more apparent for both sides."
