Boeing 737 Next Generation
airliner family (1997–present)
The Boeing 737 Next Generation, commonly abbreviated as 737NG, or 737 Next Gen, is a twin-engined narrow-body aircraft produced by Boeing Commercial Airplanes. Launched in 1993 as the third-generation derivative of the Boeing 737, it has been produced since 1997.
The 737NG is an upgrade of the 737 Classic (–300/–400/–500) series. Compared to the 737 Classic, it has a redesigned wing with a larger area, a wider wingspan, greater fuel capacity, higher maximum takeoff weight and longer range. It has CFM International CFM56-7 series engines, a glass cockpit, and upgraded and redesigned interior configurations. The series includes four variants, the –600/–700/–800/–900, seating between 108 and 215 passengers. The 737NG's primary competition is the Airbus A320 family.
As of June 2026, a total of 7,159 737NG aircraft had been ordered, of which 7,123 had been delivered, with remaining orders for two -800, and 34 -800A variants. The most-ordered variant is the 737-800, with 4,991 commercial, 224 military, and 23 corporate, or a total of 5,238 aircraft. Boeing stopped assembling commercial 737NGs in 2019 and made the final deliveries in January 2020.

Why this record matters
The phrase “airliner family (1997–present)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 17, 2026. The linked authority identifier is Q1084919. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1993, 1997, 2026 and 2019.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
