Delhi-based low-cost airline IndiGo has signed a “definitive agreement” for the purchase of 300 Pratt and Whitney engines.
The engines will power the 150 Airbus A-320 New Engine Option (NEO) family aircraft that the airline has ordered.
The agreement, which was inked at the ongoing air show in London, also has the provision of the airline going in for some additional engines.
The value of the order was, however, not made public. Deliveries are scheduled for 2015 to coincide with the delivery of the first batch of A-320 NEO aircraft ordered by the airline.
The airline had ordered the Airbus A-320 NEO family last year at an estimated value of $16 billion.
An official statement issued announcing the engine order claims benefits include double-digit reductions in fuel burn, environmental emissions, engine noise and operating costs when compared with today's engines.
“The order represents one of the largest engine orders in our history,” said Mr Todd Kallman, President, Commercial Engines & Global Services, Pratt & Whitney.
At the air show, Pratt & Whitney also delivered the first four F117 engines for the Indian Air Force to power its fleet of Boeing C-17 Globemaster III transport aircraft.
The Defence Ministry signed a letter of offer and acceptance with the US Government last year to acquire 10 C-17s.
India will take delivery of its first C-17s in mid-2013.
