The 737 is the best-selling jetliner family ever. Its low-slung fuselage, derived from the 707/727 cross-section, has shaped every generation.

The 'Baby Boeing'

The 737-100 first flew on 9 April 1967, with Lufthansa as the launch customer. The longer 737-200 followed quickly and became the version that sold. Its slim Pratt & Whitney JT8D engines were tucked under the wing, and a gravel kit let it operate from unpaved runways in Alaska and Africa.

The Classic

In the 1980s, the 737-300, -400 and -500 introduced the larger, quieter CFM56 turbofan. Because the 737 sits so low, the engine had to be flattened at the bottom — giving the Classic its famous 'hamster pouch' intakes. Nearly 2,000 Classics were built.

The Next Generation

Facing competition from the A320, Boeing launched the 737 Next Generation (-600, -700, -800, -900) in 1993. A new, larger wing gave longer range and higher cruise speed, and a six-screen glass cockpit replaced the dials. The 737-800 became one of the most successful airliners ever built.

The MAX

When Airbus launched the A320neo in 2010, Boeing chose to update the 737 again rather than design a new aircraft. The 737 MAX received the larger LEAP-1B engine, split-tip winglets and large displays. Fitting the bigger engine changed the aircraft's handling at high angles of attack, which Boeing addressed with MCAS. After two fatal accidents and a long grounding, the MAX returned to service in late 2020.
