MIAMI — Doha-based Qatar Airways has signed a Memorandum of Understanding (MoU) with luxury aircraft maker Gulfstream Aerospace to acquire up to 20 aircraft. The deal was announced at the same time Gulfstream announced its new family of business jets, the G500 and G600.

Under the MoU, Qatar Airways will take a mix of the all-new, wide-cabin G500 and Gulfstream’s ultra-long-range G650ER jet. The jets will be used for the airline’s subsidiary, Qatar Executive.

Qatar Executive, which began operating in 2009, offers air charter services for individuals, families, businesses, corporations and governments, along with  aircraft management, maintenance and handling services in the Middle East, around the world. It currently operates a fleet of Bombardier Challenger 605s, Global 5000s, and Global XRSs.

“Qatar Executive has been on an accelerated growth path since its inception and is held to an exceptional standard of quality that is widely known by our global clientele,” said Akbar Al Baker, group chief executive of Qatar Airways in a press release. “In order to keep pace with the future strategic growth plans of our private jet division, the fleet is being expanded with aircraft that meet the needs of our guests, providing a wide range of options.”

The G500 can fly 5,000 nautical miles/9,260 kilometers at Mach 0.85 or 3,800 nm/7,038 km at Mach 0.90. The aircraft will link Doha, Qatar, nonstop with London, Geneva and Paris at Mach 0.90 and is expected to enter service in 2018.  Gulfstream expects to receive type certification from the U.S. Federal Aviation Administration and European Aviation Safety Agency in 2017.
