What engines does a Boeing 777 have?
The 777-300ER is powered by GE90-115B turbofan engines, the most powerful engines manufactured, and which are only marginally smaller in diameter than the fuselage cross-section of a 737. The Rolls-Royce Trent 800 is a high-bypass turbofan produced by Rolls-Royce plc, one of the engine options for the first-generation Boeing 777 variants, also known as 777 Classics.The Rolls-Royce Trent 1000 is a high-bypass turbofan engine produced by Rolls-Royce, one of the two engine options for the Boeing 787 Dreamliner, competing with the General Electric GEnx.Other widebody aircraft Rolls-Royce Trent 800 engines are also one of the engines that power the older generation of the Boeing 777 family of aircraft, although the newer generation is powered by the General Electric GE90 turbofan.
Does the Boeing 777 use Rolls-Royce engines?
The first generation of Boeing 777 models, the -200, -200ER, and -300 have since been known collectively as the Boeing 777 Classics. These three early 777 variants had three engine options ranging from 77,200 to 98,000 lbf (343 to 436 kN): General Electric GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800. The Boeing 737 is renowned for its efficiency and versatility, making it a favorite among airlines for domestic and short international flights. In contrast, the Boeing 777 is designed for larger passenger capacities and longer distances, accommodating the demand for transcontinental and intercontinental travel.Airlines loved the 777-300ER for its GE90 engines, long range, and ability to replace 747s and A340s. But newer rivals like the A350-1000 and Boeing’s own 787-10 burn far less fuel. Demand for the older jet dwindled, and Boeing chose to close the line to focus resources on the 777X and cargo variants.Boeing’s direct replacement for the 777-300ER is the Boeing 777-9, the largest variant of its upcoming Boeing 777X family of aircraft. Slated for entry in late 2026 or early 2027, the 777-9 will have a typical three-class capacity of 349 passengers or 426 in two classes, putting it in the same bracket as the -300ER.Boeing 777 : Larger, carries 314-396 passengers. Range & Efficiency👇 – 787 : More fuel-efficient, designed for medium to long- haul routes. Can fly longer distances and carry more passengers, but uses more fuel.Boeing 777 : Larger, carries 314-396 passengers.

Which country makes the best jet engine?
The United States: GE Aerospace and Pratt & Whitney GE Aerospace exclusively provides the engines for Boeing 777 (including 777X) aircraft, remaining 767 freighters, and the most popular engine option for the Boeing 787 Dreamliner. In 2025, the aircraft with the world’s most powerful commercial engines is the Boeing 777X, powered exclusively by the GE Aerospace GE9X. It is the largest turbofan ever built, the current Guinness World Record holder for thrust, and the technological centerpiece of Boeing’s next-generation flagship.As per the Annual Strategy Dossier – 2021, the top four global commercial aircraft turbofan engine manufacturers are Pratt & Whitney, Rolls-Royce, GE Aviation and Safran.
What engine does the Boeing 777X use?
GE9X: Powering the Boeing 777X The GE9X engine from General Electric (GE) represents the latest generation of propulsion systems for long-haul airliners, specifically the new Boeing 777X widebody aircraft. The GE9X is the most powerful aircraft engine in history and the quietest GE engine ever produced (pounds of thrust per decibel). The engine will bring up to 10% specific fuel consumption improvement compared to the GE90-115B.
