Performance Improvement - Trent 700

9 July 2012

             ROLLS-ROYCE PLANS FURTHER PERFORMANCE IMPROVEMENT FOR 
                         MARKET-LEADING TRENT 700 ENGINE

Rolls-Royce, the global power systems company, plans to make further
performance improvements to its market-leading Trent 700 engine that powers the
Airbus A330.

Technologies already proven on Rolls-Royce Trent 1000, Trent XWB and BR725
engines are available to be incorporated into the Trent 700 to deliver
increased efficiency of at least one per cent. The improvement programme will
also focus on engine service support.

The Trent 700 is the best-selling member of the Trent engine family, with more
than 1,400 either sold or on order. It is the market leader on the Airbus A330,
accounting for around three quarters of future engine orders on the aircraft.

The improvement programme will be finalised this year, with enhanced engines
expected to enter service in 2015. Improvements will also be available for
retrofit to the current engine fleet. The enhanced Trent 700 will complement
the improvements to the A330 aircraft that Airbus has announced.

Tom Palmer, Rolls-Royce, Project Director - Trent 700, said: "The market's
favourite engine for the Airbus A330 is about to get even better. We are
committed to continually improving every member of the Trent family as we
develop new technology that improves efficiency. We now look forward to working
with our customers and Airbus to bring this new standard of Trent 700 to the
market, where I am sure it will prove popular for decades to come."

The Trent 700 is the only engine specifically designed for the Airbus A330 and
entered service in 1995. The improvement programme announced today is in
addition to enhancements introduced in 2009, incorporating Trent 900 and 
Trent 1000 technology, that delivered a one per cent reduction in fuel 
consumption.

At any one time 40,000 passengers are flying on a Trent 700 powered Airbus
A330. On average a Trent 700 powered A330 takes off or lands somewhere around
the world once every 40 seconds.
