It was the largest jet engine, [3] until being surpassed in January 2020 by its successor, the 110,000 lbf (490 kN) GE9X, which has a larger fan diameter by 6 inches (15 cm). However, the GE90-115B, the most recent variant of the GE90, is rated for a higher thrust (115,000 lbs) than the GE9X.
The Lycoming XR-7755 was the largest piston aircraft engine ever built in the United States, [Note 1] with 36 cylinders totaling about 7,750 in 3 (127 L) of displacement and a power output of 5,000 horsepower (3,700 kilowatts).
The NB-52B's career has come to an end with the launch of the world's most powerful airbreathing jet engine. On its final mission it launched the third X-43A Hyper-X supersonic combustion ramjet on a modified Pegasus booster that ,propelled it to a speed of Mach-9.6 (7,365mph or 11,854 kph) at an altitude of 110,000 feet.

In February 2012, GE announced studies on a more efficient derivative of the GE90, calling it the GE9X, to power both the -8 and -9 variants of the new Boeing 777X.It was to feature the same 128 in (325 cm) fan diameter as the GE90-115B with thrust decreased by 15,800 lbf (70 kN) to a new rating of 99,500 lbf (443 kN) per engine.

The NK-12 is the most powerful turboprop engine to enter service, ahead of the Europrop TP400 (in 2005). Another engine of similar size, the Pratt & Whitney T57 with 15,000 shp (11,000 kW) and 5,000 lbf (22 kN) jet thrust, ran 3,100 hours before being cancelled in 1957.

The GE4 was the most powerful engine of its era, producing 50,000 lbf (220 kN) dry, and 65,000 lbf (290 kN) with afterburner. [4] The Boeing 2707 was cancelled in 1971, putting an end to further work on the GE4.
