Boeing 737

 

The Boeing 737 is a short- to medium-range twinjet narrow-body airliner developed and manufactured by Boeing Commercial Airplanes in the United States. Originally developed as a shorter, lower-cost twin-engine airliner derived from the 707 and 727, the 737 has developed into a family of ten passenger models with capacities from 85 to 215 passengers. The 737 is Boeing's only narrow-body airliner in production, with the 737 Next Generation (-700, -800, and -900ER) and the re-engined and updated 737 MAX variants currently being built.

The 737 was originally envisioned in 1964. The initial 737-100 made its first flight in April 1967, and entered airline service in February 1968 at Lufthansa. It was followd by the lengthened 737-200, which entered service in April 1968. In the 1980s Boeing launched the longer 737-300, −400, and −500 variants (now referred to as the Boeing 737 Classic series) featuring CFM56 turbofan engines and wing improvements.

The Boeing 737 Next Generation (NG) was introduced in the 1990s, with a redesigned, increased span laminar flow wing, upgraded "glass" cockpit, and new interior. The 737 NG comprises the 737-600, −700, −800, and −900 variants, with lengths ranging from 102 to 138 ft. Boeing Business Jet versions of the 737 NG are also produced. The 737 was revised again in the 2010s for greater efficiency, with the 737 MAX series featuring CFM LEAP-1B engines and improved winglets. The 737 MAX entered service in 2017.

The 737 series is the best-selling commercial jetliner in history. The 737 has been continuously manufactured since 1967: the 10,000th was rolled out on 13 March 2018, a MAX 8 destined for Southwest Airlines, and over 4,600 orders have yet to be filled. Assembly of the 737 is performed at the Boeing Renton Factory in Renton, Washington. Many 737s serve markets previously filled by 707, 727, 757, DC-9, and MD-80/MD-90 airliners, and the aircraft currently competes primarily with the Airbus A320 family. As of 2006, there were an average of 1,250 Boeing 737s airborne at any given time, with two either departing or landing somewhere every five seconds.

Military variants of the 737 include:

Boeing 737 AEW&C: The Boeing 737 AEW&C is a 737-700IGW roughly similar to the 737-700ER. This is an Airborne Early Warning and Control (AEW&C) version of the 737NG. Australia is the first customer (as Project Wedgetail), followed by Turkey and South Korea.

C-40 Clipper: The C-40A Clipper is a 737-700C used by the U.S. Navy as a replacement for the C-9B Skytrain II. The C-40B and C-40C are used by the US Air Force for transport of generals and other senior leaders.

P-8 Poseidon: The P-8 is a 737-800ERX ("Extended Range") that was selected on June 14, 2004 to replace the Lockheed P-3 Orion maritime patrol aircraft. The P-8 is unique in that it has 767-400ER-style raked wingtips, instead of the blended winglets available on 737NG variants.
