Why The Boeing 777X Has Such Large Engines

The Boeing 777X is the newest aircraft to be developed by Boeing with a planned entry to service in 2026 with launch customer Lufthansa. The huge twinjet is the longest commercial jet ever built with a staggering length of 251 ft 9 in (76.73 m) for the 777-9, making it even longer than the Boeing 747-8 or Airbus A380. With a capacity for upwards of 425 passengers (395 on the 777-8), the widebody will be powered by two General Electric GE9X engines, the world’s largest jet engine.
