Boeing’s new 777X has been introduced as a significant obstacle in carrying passengers, which the Federal Aviation Administration has certified to be the giant jet engine developed to develop a wide-bodied aircraft. General Electric announced on Monday that the FAA has blessed GE9x, the largest commercial jet engine officially built.

“There is no alternative that can achieve the combination of size, power and fuel efficiency of the GE9X,” GE Aviation CEO John Slaty said in a statement. “This engine will provide unsurpassed value and reliability to our airline customers.”

Boeing did not release its statement on the news, but in A tweet reply to G.E. On Monday it said, “Great job and congratulations to your team!”

The 90x figures are impressive. Made of 16 blades, its fan diameter is 134 inches – almost as wide as Boeing 737 Fuselage – and 110,000 pounds of thrust at takeoff, or about twice the power of two engines 747.

GE also says that the GE9x will be the quietest GE engine ever, meeting 10% less fuel consumption. Parts of the engines are made from composite materials, including some turbine blades, which have been 3D-printed by Italian company Avio Aero.

But the GE9x also accelerated development for the 777x, the first commercial aircraft with fold-up wingtips. At the 2019 Paris Air Show, Boeing said that excessive wear inside the engine forced the company to postpone the first flight of the 777x.

The airliner, which can carry between 384 and 436 passengers depending on configuration, eventually flew for the first time in January. Although originally intended to begin carrying passengers next year, entry into service is now scheduled for 2022.
