The [Vous devez être inscrit et connecté pour voir ce lien] C-141 Starlifter was a military [Vous devez être inscrit et connecté pour voir ce lien] in service with the [Vous devez être inscrit et connecté pour voir ce lien] (AMC) of the [Vous devez être inscrit et connecté pour voir ce lien].

The aircraft also served with AMC-gained airlift wings and air mobility wings of the [Vous devez être inscrit et connecté pour voir ce lien] (AFRC) and the [Vous devez être inscrit et connecté pour voir ce lien] (ANG) and, in later years, one air mobility wing of the [Vous devez être inscrit et connecté pour voir ce lien] (AETC) dedicated to C-141, [Vous devez être inscrit et connecté pour voir ce lien], C-17 and [Vous devez être inscrit et connecté pour voir ce lien] training.

Introduced to replace slower piston-engined cargo planes such as the [Vous devez être inscrit et connecté pour voir ce lien], the C-141 was designed to requirements set in 1960 and first flew in 1963.

Production deliveries of an eventual 285 planes began in 1965: 284 for the Air Force, and one for the [Vous devez être inscrit et connecté pour voir ce lien] (NASA) for use as an airborne observatory.

The aircraft remained in service for almost 40 years until the USAF withdrew the last C-141s from service in 2006, after replacing the airlifter with the [Vous devez être inscrit et connecté pour voir ce lien].

Design and development

In the early 1960s, the United States Air Force [Vous devez être inscrit et connecté pour voir ce lien] (MATS) relied on a substantial number of propeller-driven aircraft for strategic airlift.

As these aircraft were mostly obsolescent designs and the Air Force needed the benefits of jet power, the USAF ordered 48 [Vous devez être inscrit et connecté pour voir ce lien] as an interim step.

The C-135 was a useful stop-gap, but only had side-loading doors and most bulky and oversize equipment would not fit,
especially that employed by the [Vous devez être inscrit et connecté pour voir ce lien].

In the spring of 1960 the Air Force released Specific Operational Requirement 182, calling for a new aircraft that would be capable of performing both strategic and tactical airlift missions.

The strategic role demanded that the aircraft be capable of missions with a radius of at least 3,500 nmi (4,000 mi, 6,500 km) with a 60,000 lb (27,000 kg) load.

The tactical role required it to be able to perform low-altitude air drops of supplies, and carry and drop paratroops in combat.

Several companies responded to SOR 182, including [Vous devez être inscrit et connecté pour voir ce lien], Lockheed and [Vous devez être inscrit et connecté pour voir ce lien].^{[Vous devez être inscrit et connecté pour voir ce lien]}

Lockheed responded to the requirement with a unique design: the Lockheed Model 300, the first large jet designed from the start to carry freight.

The Model 300 had a swept high-mounted wing with four 21,000 lbf (93.4 kN) thrust[Vous devez être inscrit et connecté pour voir ce lien] turbofan engines pod-mounted below the wings.

An important aspect was the cabin floor's height of only 50 in (1.27 m) above the ground, allowing easy access to the cabin through the rear doors.

The two rear side doors were designed to allow the aircraft to drop paratroopers (in August 1965 the type performed the first paratroop drop from a jet-powered aircraft).

The rear cargo doors could be opened in flight to allow airborne freight drops.

The shoulder-mounted wings gave internal clearance in the cargo hold of 10 ft (3.05 m) wide, 9 ft (2.74 m) high
and 70 ft (21.34 m) long.

The size enabled the Starlifter to carry, for example, a complete [Vous devez être inscrit et connecté pour voir ce lien] intercontinental ballistic missile in its container.

The aircraft was capable of carrying a maximum of 70,847 lb (32,136 kg) over short distances, and up to 92,000 lb (41,730 kg) in the version configured to carry the Minuteman, which stripped other equipment.

The aircraft could also carry up to 154 troops, or 123 fully-equipped paratroopers.

President [Vous devez être inscrit et connecté pour voir ce lien]'s first official act after his inauguration was to order the development of the Lockheed 300 on 13 March 1961, with a contract for five aircraft for test and evaluation to be designated the C-141.

One unusual aspect of the aircraft was that it was designed to meet both military and civil airworthiness standards.

The prototype C-141A serial number 61-2775 was manufactured and assembled in record time, being rolled out of the
Lockheed factory at Marietta, Georgia on 22 August 1963 and first flying on 17 December, the 60th anniversary of the Wright brothers' first flight.

The company and the Air Force then started an operational testing program and the delivery of 284 aircraft, initially to units of the MATS, later renamed the [Vous devez être inscrit et connecté pour voir ce lien] (MAC) in 1966.

An effort to sell the aircraft on the civilian market resulted in provisional orders from [Vous devez être inscrit et connecté pour voir ce lien] and Slick Airways for four aircraft each.

These were to be a stretched version, 37 ft (11.28 m) longer than the C-141A, and marketed as the L-300 SuperstarLifter.

Other changes were also incorporated to make more commercial including a different yoke.

The development was not sustained and only one civilian demonstration aircraft was built.

When no commercial sales were made Lockheed donated the aircraft to [Vous devez être inscrit et connecté pour voir ce lien].

Operational history

The prototype and development aircraft then began an intensive operational testing program including the first delivery to MATS (63-8078) on 19 October 1964 to the 1707th Air Transport Wing, Heavy (Training), [Vous devez être inscrit et connecté pour voir ce lien], Oklahoma.

Testing continued and a Federal Aviation Authority type certificate was awarded on 29 January 1965.

The first delivery to an operational unit (63-8088) was made on 23 April 1965 to the 44th Air Transport Squadron,
1501st Air Transport Wing, [Vous devez être inscrit et connecté pour voir ce lien], California.^{[Vous devez être inscrit et connecté pour voir ce lien][Vous devez être inscrit et connecté pour voir ce lien]}

Although operational testing continued, due to the United States' military involvement in South Vietnam, the C-141 was soon employed in operational sorties to the combat zone.

On 8 January 1966, following the disestablishment of MATS, all C-141s were transferred to the newly established [Vous devez être inscrit et connecté pour voir ce lien] (MAC).

On 1 June 1992, following the disestablishment of Military Airlift Command (MAC), all C-141s and the airlift wings to which they were assigned were transferred to the newly-established [Vous devez être inscrit et connecté pour voir ce lien] (AMC).

[Vous devez être inscrit et connecté pour voir ce lien] (AFRC) and [Vous devez être inscrit et connecté pour voir ce lien] (ANG) C-141s and units were were also transferred to AMC.

On 16 September 2004, the C-141 left service with nearly all active duty USAF units, being confined to [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] units for the remainder of its operational service life.

As of 25 September 2005, there were only eight C-141 aircraft still flying, all from the [Vous devez être inscrit et connecté pour voir ce lien]'s [Vous devez être inscrit et connecté pour voir ce lien] (445 AW) at [Vous devez être inscrit et connecté pour voir ce lien].

In 2004, 2005, and 2006, the C-141s assigned to the 445 AW participated in missions to [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien], mostly for the medical evacuation of wounded service members.

The last eight C-141s were officially retired in 2006

In 2002 one of the last operational aircraft at [Vous devez être inscrit et connecté pour voir ce lien] was identified by its crew chief as the [Vous devez être inscrit et connecté pour voir ce lien] (AF Serial Number 66-0177), one of the aircraft used in 1973 for [Vous devez être inscrit et connecté pour voir ce lien] in the final days of the [Vous devez être inscrit et connecté pour voir ce lien], to [Vous devez être inscrit et connecté pour voir ce lien] from [Vous devez être inscrit et connecté pour voir ce lien].

In 2005, Hanoi Taxi and other aircraft were marshalled by the Air Force to provide evacuation for those seeking refuge from [Vous devez être inscrit et connecté pour voir ce lien].

This aircraft and others evacuated thousands of people, including the [Vous devez être inscrit et connecté pour voir ce lien] of hundreds of ill and injured.

With the 5 May 2006 announcement of the retirement of these last eight C-141s, the Hanoi Taxi embarked on a series of flights, giving veterans, some of whom flew out of POW captivity in Vietnam in this aircraft, the opportunity to experience one more flight before retirement. On 6 May 2006, the Hanoi Taxi piloted by Col. James F. Blackman and Col. Benjamin Johnson, landed for the last time and was received in a formal retirement ceremony at the [Vous devez être inscrit et connecté pour voir ce lien], located at [Vous devez être inscrit et connecté pour voir ce lien] in [Vous devez être inscrit et connecté pour voir ce lien] near [Vous devez être inscrit et connecté pour voir ce lien].[Vous devez être inscrit et connecté pour voir ce lien]

Variants

C-141A

The original Starlifter model, designated C-141A, could carry 154 passengers, 123 paratroopers or 80 litters for wounded with seating for 16. A total of 284 A-models were built.

The C-141A entered service in April 1965. It was soon discovered that the aircraft's volume capacity was relatively low in comparison to its lifting capacity; it generally ran out of physical space before it hit its weight limit.

The C-141A could carry ten standard [Vous devez être inscrit et connecté pour voir ce lien] and had a total cargo capacity of 62,700 lb (28,900 kg).

It could also carry specialized cargoes, such as the [Vous devez être inscrit et connecté pour voir ce lien].

NASA obtained Lockheed's C-141 demonstrator, designated L-300. The airplane was modified to house the [Vous devez être inscrit et connecté pour voir ce lien] telescope for use at very high altitudes.

This NASA NC-141A is now in storage at [Vous devez être inscrit et connecté pour voir ce lien], [Vous devez être inscrit et connecté pour voir ce lien], CA.
