The Lockheed C-141 Starlifter is a military strategic airlifter in service with the US Air Force. Introduced to replace slower piston-engined cargo planes such as the C-124 Globemaster II, the C-141 was designed to a 1960 requirement and first flew in 1963; production deliveries of an eventual 248 began in 1965, and the aircraft is still in service almost 40 years later, although the USAF plans to withdraw the C-141 from service in 2006 when sufficient C-17 Globemaster III aircraft are available. On 16 September 2004 the C-141 left service with active duty USAF units, being confined to reserve units for the remainder of its service life.
To correct this and use the C-141 to the full, the whole fleet of aircraft were stretched, producing the C-141B. Additional 'plug' sections were added before and after the wings, lengthening the fuselage by 23 ft 4 in (7.11 m) and allowing the carriage of 3 more standard pallets or an equivalent increase in other loads. Also added at this time was a boom receptacle for inflight refueling. The conversion program took place between 1977 and 1982. It was estimated that this stretching program was the equivalent of buying 90 new aircraft, in terms of increased capacity.
More recently, 63 aircraft have been upgraded to C-141C status, with improved avionics and navigation systems, to keep them up-to-date until C-17s are available to replace them.
In 1994, thirteen C-141Bs were given SOLL II (Special Operations Low-Level II) modifications, which gave the aircraft a low-level night flying capability, enhanced navigation equipment, and improved defensive countermeasures. The USAF operates these aircraft for the Air Force Special Operations Command. These aircraft are slated to be replaced by special-purpose new-build C-17s.
