"Rolls-Royce has been selected by Singapore Airlines Group to power 50 Boeing 787 Dreamliner aircraft with Trent 1000 engines," the company said in a statement. "The announcement, which includes long-term TotalCare service support, is worth $4.0 billion at current list prices."
Rolls-Royce added that 30 Boeing 787-10X aircraft will be operated by Singapore Airlines.
The airline's subsidiary, Scoot, will operate 10 Boeing 787-8 and 10 Boeing 787-9 aircraft.
Singapore Airlines and Scoot currently operate a total of 88 Rolls-Royce powered aircraft, with 88 more on the order books.
"We are very proud that Singapore Airlines, one of the most respected carriers in the world, and its subsidiary Scoot have placed their trust in our Trent 1000 and our ability to deliver superior product and service performance," said Eric Schulz, president of Rolls-Royce’s civil aircraft engine unit.
"This decision is a tremendous reflection of the deep relationship that Rolls-Royce and Singapore Airlines enjoy, and allows us to continue to develop our strategic alignment," Schulz said.
