Rolls-Royce BR725 engines will power Gulfstream's new ultra-long-range business jet - the G650ER, announced today at the EBACE airshow in Geneva, Switzerland.

The aircraft, which will enter service in 2015, offers a unique range of 7,500 nautical miles at Mach 0.85 and 6,400 nm/11,853 km at Mach 0.90.

Russell Buxton, Rolls-Royce, President, Civil Small and Medium Engines, said: "We are delighted that Gulfstream has selected the BR725 for this latest version of the G650, following the excellent entry into service of the original aircraft. We look forward to continuing a relationship of more than 50 years that stretches back to the first Gulfstream business aircraft.

"The BR725 incorporates technology from the market-leading Trent widebody engine family and was designed with excellent fuel efficiency and ample thrust margins that support the G650ER's enhanced performance."

Scott Neal, Gulfstream, Senior Vice President, Worldwide Sales and Marketing, said: "The G650ER provides our customers with greater mission flexibility and the longest range of any business jet. We look forward to working with Rolls-Royce to bring it into service."

In recent years, Rolls-Royce has powered five high-performance Gulfstream business jets into service - the ultra-long-range G550 (2003), the G500 (2004), the large-cabin, midrange G350 and the long-range G450 (both in 2005) and the ultra-long-range G650 in 2012.

More than 200 BR725 engines have already been built at Rolls-Royce's Dahlewitz site in Germany. The engine is part of the Rolls-Royce BR700 engine family that has accumulated more than 16 million flying hours to date and also comprises the BR710 and BR715.
