They have since been collectively referred to as 777 Classics. The initial 777-200, extended-range -200ER, and -300 versions are equipped with General Electric GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines.

The original 777-200 variant entered commercial service in 1995, followed by the extended-range 777-200ER in 1997. The 777 is produced in two fuselage lengths as of 2018. It was also the first commercial aircraft to be designed entirely with computer-aided design. As Boeing's first fly-by-wire airliner, it has computer-mediated controls. Developed in consultation with eight major airlines, the 777 was designed to replace older wide-body airliners and bridge the capacity difference between Boeing's 767 and 747. Commonly referred to as the 'Triple Seven', its distinguishing features include the large–diameter turbofan engines, long raked wings, six wheels on each main landing gear, fully circular fuselage cross-section, and a blade-shaped tail cone. It is the world's largest twinjet and has a typical seating capacity of 314 to 396 passengers, with a range of 5,240 to 8,555 nautical miles (9,704 to 15,844 km). The Boeing 777 ( Triple Seven) is a long-rangewide-bodytwin-enginejet airliner developed and manufactured by Boeing Commercial Airplanes.
