"We are delighted the Indian air force has selected the C-17 with Pratt and Whitney F117 engines to support its airlift mission," said Bev Deachin, vice president, Military Programs and Customer Support, Pratt and Whitney.
"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.
"We look forward to helping strengthen India's aerospace capabilities and humanitarian efforts."
The F117-PW-100 is a sibling of the company's PW2037, a commercial engine.
India is to receive 10 of the heavy lift C-17s under an agreement with the U.S. government. The first aircraft is to be delivered in 2013.
Pratt and Whitney said 239 Globemaster IIIs delivered by Boeing the U.S. military and also to customers around the world are powered by its F117 engines.
