Pratt & Whitney Share of Vietnam Airlines Order Valued at $235 Million

FARNBOROUGH AIR SHOW, Tuesday, July 20, 2010

Vietnam Airlines has again selected International Aero Engines (IAE) for an order for V2500 engines to power a new fleet of 36 Airbus A321 aircraft. The value to Pratt & Whitney of the order is approximately $235 million. Pratt & Whitney is a United Technologies Corp. (NYSE: UTX) company and a major participant in IAE.

Vietnam Airlines will purchase 26 of the aircraft that make up the order while the remaining 10 will be owned by Vietnam Aircraft Leasing Company. Deliveries are scheduled to begin in 2011.

The V2500 is available in seven different thrust settings, from 22,000 to 33,000 lbs., to power the Airbus A319, A320 and A321 family of aircraft as well as the A319 Corporate Jet.

The V2500 SelectOneTM build standard delivers an additional 1 percent fuel burn advantage, along with a corresponding reduction in CO2 emissions, and it improves time on-wing by up to 20 percent, compared to a standard V2500-A5. It is compliant with the most stringent CAEP/6 NOx standards. It entered service in October 2008.

IAE is a multinational aero engine consortium comprised of Pratt & Whitney, Rolls-Royce, the Japanese Aero Engines Corporation and MTU Aero Engines. There are more than 5,500 V2500s in service or on firm order around the world.

Pratt & Whitney is a world leader in the design, manufacture and service of aircraft engines, space propulsion systems and industrial gas turbines. United Technologies, based in Hartford, Conn., is a diversified company providing high technology products and services to the global aerospace and building industries.
