- The Trent XWB gained certification in February 2013 following a successful flight test programme on an Airbus A380 test aircraft. The Trent XWB is the world’s most efficient large jet engine and is the fastest-selling Trent engine, with orders for more than 1,200 engines already received.
- We launched the Trent 1000-TEN that is due to enter service in 2016. This engine, which incorporates proven next generation technology from the Trent XWB, will be capable of powering all versions of the Boeing 787.
- The BR725-powered Gulfstream G650 entered service early in 2013, and the AE3007C-powered Cessna Citation TEN is due to enter service later this year.
