Rolls-Royce says Boeing's decision to power the 777X with only the GE9X engine maintains the status quo in the marketplace.

"This decision simply maintains the existing situation in the widebody market in which we are the market leader with over 50% share," R-R says.

Most industry observers expected Boeing to select the GE9X to exclusively power the new widebody, as the GE90 already does with the 777-300ER, -200LR and Freighter.

But R-R last year unveiled a proposal based on the RB3025, which boasted a wider fan diameter and higher overall pressure ratio than the GE9X.

"We are confident that the proposal we put forward was extremely competitive," R-R says.

The R-R Trent XWB engine is the only engine supplier currently for the Airbus A350XWB family.
