This engine powered a Korean Air Lines Boeing 777-300 aircraft. The PW4000 series engine replaced Pratt & Whitney's highly successful JT9D, which powered the Boeing 747, the first jumbo-jet. The newer engine takes advantage of technology from the NASA Energy Efficient Engine program, and provides power for many wide-body aircraft, including the A310, A300-600, A330, B767, and MD-11.

This 284-cm (112-inch) fan model is the second derivative in the PW4000 engine family, and is nearly as wide as the fuselage of a Boeing 737. The PW4084, certified at 386 kN (86,760 pounds) thrust, was the launch engine for the B777, entering service in 1995. The PW4098 was certified in 1998 and powers B777-200ER and 777-300 wide-body aircraft. It uses single-crystal materials, powdered metal disks, low NOx combustor technology, and an improved Full-Authority Digital Electronic Control (FADEC). It was the first engine to operate with approval for 207-minute Extended-range Twin-engine Operations (ETOPS).
