Vietnam Airlines, the national flag carrier of Vietnam, has selected the Pratt & Whitney PW4084D engine to power four 777-200ER aircraft that the airline ordered from Boeing in December last year.
The value of the contract to Pratt & Whitney is approximately $145 million.
Vietnam Airlines will begin operating these 777s next year with the first two scheduled for delivery in August and September of 2003. The other two aircraft will be delivered in 2004 and 2005.
The order will bring Vietnam Airlines’ total number of Pratt & Whitney-powered aircraft to 12 including one PW4060 powered 767-300ER leased from ILFC and seven ATRs powered by Pratt & Whitney Canada PW124B and PW127F engines.
The PW4000 family of engines powers not only the Boeing 777, but also other wide-body aircraft built by Boeing and Airbus. More than 60 airlines around the world operate PW4000s. The three PW4000 models, with fan diameters of 94 inches, 100 inches and 112 inches, can produce anywhere from 52,000 to 98,000 pounds of thrust. The 98,000-pound version of the engine is the most powerful in service today in commercial aviation.
