The original 777 with a maximum takeoff weight (MTOW) of 545,000–660,000 lb (247–299 t) was produced in two fuselage lengths: the initial 777-200 was followed by the extended-range -200ER in 1997; and the 33.25 ft (10.13 m) longer 777-300 in 1998.

Its maximum takeoff weight is targeted for 775,000 lb (351.5 t) like the 777-300ER but Boeing hopes to have at least a 10,000 lb (4.5 t) margin at introduction. [89] Boeing predicts the -8 to be 4% more fuel efficient and cost effective than the A350-1000, while the -9 would be 12% more fuel efficient and 11% more cost effective. [ 90 ]

As one of the three available engines for the all-new Boeing 777 large twinjet airliner, the GE90 was an all-new $2 billion design in contrast to the offerings from Pratt & Whitney and Rolls-Royce which were modifications of existing engines. [14] The first General Electric-powered Boeing 777 was delivered to British Airways on November 12 ...
Takeoff weight components. The maximum takeoff weight (MTOW) or maximum gross takeoff weight (MGTOW) or maximum takeoff mass (MTOM) of an aircraft, also known as the maximum structural takeoff weight or maximum structural takeoff mass, [1] is the maximum weight at which the pilot is allowed to attempt to take off, due to structural or other limits.
Aircraft such as the Boeing 707 and 727 and the Douglas DC-8 had fuel dump systems. Any of those aircraft needing to return to a takeoff airport above the maximum landing weight would jettison an amount of fuel sufficient to reduce the aircraft's weight below that maximum landing weight limit, and then land.
In the United States, the FAA uses a slightly different categorization, adding a block between medium and heavy, labeling aircraft capable of maximum takeoff weights more than 41,000 pounds (19 t) and less than 300,000 pounds (140 t) as "Large". [7] Of special note here is the narrow-bodied Boeing 757.
