The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aviation for the Boeing 777, with thrust ratings from 81,000 to 115,000 lbf (360 to 510 kN). It entered service with British Airways in November 1995. It is the most powerful and was the largest jet engine, until its 6 in (15 cm) wider fan successor, the 105,000 lbf (470 kN) GE9X, powered the Boeing 777X first flight in January 2020.
