Boeing says the 777X will be both the largest and most efficient twin-engine jet in the world. The wings are based on those of the 787 Dreamliner and will stretch to 233 feet (71 m) when extended. The company says that a GE9X engine, built by GE Aviation, will contribute to overall fuel savings.
"The airplane will build on the market-leading 777 and will provide superior operating economics," says Boeing Commercial Airplanes President and CEO Ray Conner. "The airplane will be 12 percent more fuel efficient than any competing airplane." The company has already received a reported 342 orders for the new aircraft.
The 777X was launched with two siblings – the 777-9X and the 777-8X. Boeing states that the 9X will have a range of more than 8,200 nautical miles (15,185 km) and the lowest operating cost per seat of any commercial airplane, whilst the 8X will offer a range of more than 9,300 nautical miles (17,220 km). Production is due to begin in 2017, with the first deliveries in 2020.
