Pratt & Whitney has received a contract to produce the first four F117-PW-100 engines that will power the Boeing C-17 Globemaster III for the Indian air force.

“The engines will be delivered in second quarter of 2012,” a Pratt official says. No financial details were given by the company, a unit of United Technologies Corp. India will take delivery of its first C-17s in early 2013.

Earlier this year, India’s defense ministry signed a letter of offer and acceptance with the U.S. government to acquire 10 C-17s.

In June, India’s federal Cabinet Committee on Security, a panel comprised of ministers and chaired by the prime minister, approved the purchase of the strategic heavy-lift aircraft at a cost of $4.1 billion from the U.S.

“The F117 is suited for a wide range of operating environments and conditions and it has demonstrated superb performance and reliability from the Antarctic to the deserts of the Middle East,” says Bev Deachin, Pratt’s vice president for military programs and customer support. “We look forward to helping strengthen India’s aerospace capabilities and humanitarian efforts.”

According to Pratt & Whitney, Boeing has delivered 239 C-17s featuring F117 engines worldwide, including 25 with international customers.
