The Boeing 737 Classic is the -300/-400/-500 series of the Boeing 737, so named following the introduction of the -600/-700/-800/-900 series. They are short- to medium- range, narrow-body jet airliners produced by Boeing Commercial Airplanes. The Classic series was introduced as the 'new generation' of the 737. Produced from 1984 to 2000, 1,989 aircraft were delivered.

Grand total 737 orders stand at over 4236, of which over 1104 are for
the 300. Approximately 1070 737-300s were in service at late 1998.
Short to medium range narrowbody airliner
The 737-300 is the first of the three member second generation CFM56
powered 737 family, which also comprises the stretched 737-400 and
shortened 737-500. The success of the second generation Boeing 737
family pushed sales of the mark to over 3000, a record for a commercial
jetliner.
Boeing
announced it was developing the 737-300 in March 1981. This new variant
started off as a simple stretch over the 737-200 but Boeing decided to
adopt the CFM International CFM56 high bypass turbofan (jointly
developed by General Electric and SNECMA) to reduce fuel consumption and
comply with the then proposed International Civil Aviation Organisation
Stage 3 noise limits.
Despite
the all new engines and the 2.64m (104in) fuselage stretch, the 737-300
retains 80% airframe spares commonality and shares the same ground
handling equipment with the 737-200. A number of aerodynamic
improvements were incorporated to further improve efficiency including
modified leading edge slats and a new dorsal fin extending from the
tail. Another feature was the flattened, oval shaped engine nacelles,
while the nosewheel leg was extended to increase ground clearance for
the new engines. Other internal changes include materials and systems
improvements first developed for the 757 and 767 programs, including an
early generation EFIS flightdeck (with four colour CRT screens).
The
737-300 flew for the first time on February 24 1984, while first
deliveries were from November 1984. Since that time well over 1000
737-300s have been sold and it forms the backbone of many airlines'
short haul fleets.
The stretched 737-400 and shortened 737-500 are described separately.
