General Electric Built The GE9X So Powerful That It Set A World Record For Jet Engine Thrust

The most powerful commercial jet engine ever constructed is certified to fly at a lower takeoff thrust rating than the engine it replaces. During an engineering red-line test on November 10, 2017, at GE Aerospace's outdoor facility in Peebles, Ohio, the massive GE9X turbofan generated a peak output of 134,300 pounds-force (597.4 kilonewtons). Guinness World Records officially recognized the milestone in July 2019, shattering the previous world record of 127,900 pounds-force (568.9 kilonewtons) held for 17 years by GE's own GE90-115B. This record is enough to get any aviation enthusiast excited, but when the twin-engine Boeing 777X enters airline service, its propulsion units will operate capped at a baseline rating of 110,000 pounds-force (489.3 kilonewtons), 5,000 pounds-force (22.2 kilonewtons) less than the Boeing 777-300ER.
