Rolls-Royce has won a significant deal to supply dozens of engines for a new fleet of aircraft.

The Derby-based firm's civil aerospace division will build 60 Trent 7000 engines - to power 30 Airbus A330-900neo aircraft - ordered by the Hong Kong flag carrier Cathay Pacific.

The airline has also signed a TotalCare service agreement with Rolls-Royce, covering wing and maintenance work for the aircraft.

Ewen McDonald, chief customer officer for Rolls-Royce's civil aerospace division, said the combined aircraft and engines will reduce emissions by 14%.

Mr McDonald added: “The Trent 7000, coupled with TotalCare, is a compelling proposition for airline customers and this order shows significant confidence in the Trent 7000/A330neo combination.

“This will make Cathay Pacific the world’s largest operator of Trent 7000 engines, which will benefit from the £1bn investment we’re making to the Trent engine family.

“All of us at Rolls-Royce are proud of the trust that Cathay Pacific is placing in us, and we look forward to supporting these new aircraft as they enter service.”

Cathay Pacific said the aircraft and engine combination will provide "excellent comfort" for passengers and "improved fuel efficiency".
