Rolls-Royce has won an order potentially worth £1.13 billion to supply aircraft engines to US airline Northwest.
The American carrier has selected the Rolls-Royce Trent 1000 engine for its new fleet of Boeing 787 Dreamliner planes.
Northwest has 18 firm orders for the 787 plus 18 options. Deliveries are due to begin in August 2008.
Rolls-Royce civil aerospace president Mike Terrett said yesterday: "The partnership of the Dreamliner and the Trent 1000 will enable Northwest to grow its international route network with world- best levels of technical efficiency and operating economics.
"This selection marks the beginning of what we hope will be a long and fruitful relationship between Northwest and Rolls-Royce."
Northwest president and chief executive Doug Steenland said: "The Rolls-Royce team worked closely with us to define a solution that meets Northwest's needs."
Orders have now been placed for 70 Trent 1000-powered Boeing 787s. Previous deals involved a 50-aircraft order from launch customer ANA of Japan and two Dreamliners for Air New Zealand.
