Boeing 737 Next Generation

The Boeing 737 Next Generation, commonly abbreviated 737NG, is a twin-engined narrow-body aircraft produced by Boeing Commercial Airplanes. Launched in 1993 as the third-generation derivative of the 737, it has been produced since 1997. It upgrades the 737 Classic with a redesigned wing of larger area and wider span, greater fuel capacity, higher maximum takeoff weight and longer range, CFM International CFM56-7 engines, a glass cockpit and redesigned interiors. The series has four variants, the -600, -700, -800 and -900, seating between 108 and 215 passengers, and its main competitor is the Airbus A320 family. The first NG to roll out was a 737-700 on 8 December 1996, which first flew on 9 February 1997. As of September 2026, 7,159 had been ordered and 7,124 delivered, the 737-800 being the most ordered variant; Boeing stopped assembling commercial NGs in 2019 and the 737 MAX supersedes it.
