US aero engine maker Pratt & Whitney has been awarded a contract with a value up to $1.05bn to deliver F-117 military transport engines to the US Air Force
The contract covers engines that will be delivered between 2007 to 2012 in support of the air force’s C-17 aircraft program. The C-17 troop and cargo delivery aircraft, which is around 174ft long with a 170ft wingspan, is powered by four of the fully-reversible Pratt & Whitney F117-PW-100 engines.
The F117-PW-100 engine itself is a derivative of Pratt & Whitney’s PW2000 commercial engine currently used on the Boeing 757.
In another whopping $1.3bn deal with the US Air Force, the company has also agreed to deliver F-119 engines for the F-22 Raptor over a three year period between 2008 and 2010.
The F-22 Raptor is a stealth fighter aircraft that is also is equipped for ground attack, electronic warfare and signals intelligence roles.
The dual Pratt & Whitney F119-PW-100 on the aircraft turbofans feature a unique thrust-vectoring nozzle design, and enable the F-22 to supercruise, or achieve supersonic speeds, without the use of the afterburner.
