346th Tactical Airlift Squadron

The 346th Tactical Airlift Squadron is an inactive United States Air Force squadron that was last assigned to the 314th Tactical Airlift Wing at Ching Chuan Kang Air Base, Republic of China, where it was inactivated in May 1971.

The squadron was first activated as the 346th Troop Carrier Squadron in the Air Force Reserve in 1949 and trained at Memphis Municipal Airport, Tennessee. In 1951 it was called to active duty for the Korean War and served until 1953.

In 1955 the unit was activated at Sewart Air Force Base, Tennessee as a rotary wing troop carrier assault unit in a test of the USAF's ability to support United States Army assault operations. It participated in Operation Sage Brush, which was, in part, a test of this concept. The squadron was inactivated the following year and its aircraft distributed to helicopter support organizations.

A few months later the squadron was activated as a fixed wing troop carrier assault unit at Sewart and equipped with Fairchild C-123 Provider aircraft. It moved to Pope Air Force Base, North Carolina in 1958 when Tactical Air Command consolidated its C-123 units there and continued to fly the Provider until 1963, although after December 1961 most of the squadron was deployed to Southeast Asia.

In 1963 the squadron moved on paper to Dyess Air Force Base and converted the Lockheed C-130 Hercules. The 346th moved to the Pacific in 1969 and began to deploy C-130s to Southeast Asia from Ching Chuan Kang Air Base, (commonly referred to as CCK) where it was assigned to the 314th Troop Carrier Wing. The squadron was inactivated at CCK as USAF operations in Southeast Asia were reduced.

Reserve training and Korean War callup
The squadron was activated in the reserves in 1949 and assigned to the 516th Troop Carrier Group. The squadron trained under the supervision of the 2584th Air Force Reserve Training Center at Memphis Municipal Airport, Tennessee until April 1951. The 346th was called to active duty that month and participated in tactical exercises and worldwide airlift. The exercises included a cold weather exercise (Snowfall) and a desert exercise (Longhorn). It converted from Curtiss C-46 Commando to Fairchild C-119 Flying Boxcar aircraft in 1952. The 346th was inactivated and replaced by the 773d Troop Carrier Squadron in January 1953.

Helicopter assault operations
The squadron was reactivated in 1955 and assigned to the 516th Troop Carrier Group at Sewart Air Force Base, Tennessee as the 346th Troop Carrier Squadron, Assault, Rotary Wing in part to test the United States Air Force's ability to provide helicopter airlift to the Army. The 346th was initially equipped with Sikorsky H-19 helicopters, but soon replaced them with Piasecki H-21s. Its operations included participation in Operation Backlash II, which was a survey mission to fix the location of radar sites and support the construction of the Mid-Canada Line. The group also tested the evacuation of key high ranking personnel from Washington DC in the event of a nuclear attack.

The conflict between the Army and the Air Force concerning the use of Air Force helicopters to support Army assault operations was tested in Operation Sage Brush. The 346th operated as part of the aggressor force. The squadron's H-21s were dismantled and transported in Douglas C-124 Globemaster II aircraft in a test of air mobility. Following this test, the 346th was inactivated in July 1956. The helicopters of the squadron were transferred to the 23d Helicopter Squadron.

C-123 operations
Three months later, the squadron was reactivated at Sewart as a Fairchild C-123 Provider unit. The squadron trained to airlift troops, equipment and supplies into combat zones, to resupply forces, and evacuate casualties. In 1958, the squadron and most of the C-123s at Sewart were transferred to Pope Air Force Base, North Carolina and the squadron's parent 513th Troop Carrier Wing was inactivated. While at Pope the squadron was attached to the 464th Troop Carrier Wing.

The C-123 was programmed to be removed from service in 1961, but events overtook this decision. On 22 November 1961 the United States offered to provide increased airlift support to the government of the Republic of Viet Nam (South Vietnam). By January 1962, sixteen of the squadron's aircraft had deployed to the Pacific area. Initially, four aircraft were stationed "in country" at Tan Son Nhut Airport outside Saigon. Four more were at Clark Air Base in the Philippines while the remaining aircraft were en route to Clark, where they would be able to rotate "in country." Among their duties, the instructor pilots of the 346th checked out pilots of Air America, which was beginning to operate C-123s as well.

Three of these aircraft had been sent to Olmsted Air Force Base, Pennsylvania for modification, adding MC-1 tanks and aerial spray booms. On 13 January two of these aircraft flew the first mission of Operation Ranch Hand. The Ranch Hand aircraft were later transferred to Detachment 1, 315th Troop Carrier Group, Commando.

The remaining deployed aircraft flew as Operation Mule Train, which was intended to provide the Army of the Republic of Viet Nam (ARVN) with an assault capability with either airdrop or insertion. However, once in place, the unit also filled the need for logistic support to remote sites throughout the country. Mule Train crews often had to operate independently with little air traffic control under marginal weather conditions, flying in and out of small fields located in mountainous areas. In June the squadron was augmented by the 777th Troop Carrier Squadron. The Air Force placed great confidence in young Mule Train aircraft commanders, many of them first lieutenants. They were given authority to conduct operations with little oversight. Two Mule Train aircraft were maintained at Da Nang Air Base (at first referred to by its French name of Tourane Airport) to support northern outposts

The first large airdrop mission by Mule Train took place on 28 June 1962. Sixteen C-123s accompanied by a dozen Douglas C-47 Skytrains of the Vietnam Air Force (VNAF) dropped paratroops about 35 miles north of Saigon despite a 500 foot ceiling. The Providers even added napalm bombing to their mission. The plane would carry nine wooden pallets, each holding three 55-gallon drums of napalm mixed with gasoline. With a good kicker, the load could go out the back ramp in less than five seconds and leave a pattern of flame 1,200 feet long.

In April 1963 the squadron moved on paper to Dyess Air Force Base, Texas, where it became a Lockheed C-130 Hercules squadron. Its aircraft at Pope were transferred to the newly activated 309th Troop Carrier Squadron, Commando, which moved to Viet Nam three months later.

C-130 operations
At Dyess, the squadron performed tactical airlift worldwide, deploying to the Far East, Europe and the Panama Canal Zone. The squadron participated in a constant stream of exercises and operations.

As the United States Air Force (USAF) built up its forces in the Pacific as the Vietnam War grew larger the squadron moved to Ching Chuan Kang Air Base, Republic of China (usually called "CCK"). Although the squadron itself was not stationed in Viet Nam, it flew C-130s to augment task forces and other operational organizations during Vietnam War until it was inactivated in 1971 when the 314th wing returned to the US. Its mission, personnel and equipment were transferred to the 21st Tactical Airlift Squadron, which moved on paper to CCK from Naha Air Base, Okinawa.
