Rolls-Royce today welcomed a decision by Japan Airlines to order 31 Airbus A350 XWB aircraft, which are powered by Rolls-Royce Trent XWB engines.

The Trent XWB, the world’s most efficient engine flying today, will power 18 A350-900 and 13 A350-1000 aircraft.

The engine powered the A350 XWB to its first test flight in June this year at the Airbus base in Toulouse, France.

The Trent XWB engine benefits from a close partnership with Japanese partners Kawasaki Heavy Industries (KHI), Mitsubishi Heavy Industries (MHI), IHI Corporation, and Sumitomo Precision Products (SPP) as well as other Japanese suppliers.
