# 486th Bombardment Squadron

The 486th Bombardment Squadron is an inactive United States Air Force unit. It was last assigned to the 22d Bombardment Wing at March Air Force Base, California, where it was inactivated on 1 July 1971.
The squadron was activated in 1942 and trained with North American B-25 Mitchells in the United States before deploying to the Mediterranean Theater of Operations in early 1943. It flew combat missions in the Mediterranean until 1945, earning a Distinguished Unit Citation for its actions. Following V-E Day, the squadron returned to the United States, where it was inactivated.
The squadron was activated again in the reserves in 1947, but does not appear to have been fully manned or equipped during this period. It was inactivated two years later as a result of Defense budget reductions.
The squadron was reactivated in 1952 as a Strategic Air Command bomber unit flying Boeing B-47 Stratojets. It was put on full alert at dispersed bases in 1962 for the Cuban Missile Crisis. In 1963, it moved to assume the personnel and Boeing B-52 Stratofortresses of another unit. While flying the "BUFF", the squadron deployed personnel and bombers to participate in the Vietnam War until it was inactivated in 1971 as older models of the B-52 were being phased out of active service.

## History
### World War II
#### Initial organization and training

The squadron was first activated at Columbia Army Air Base, South Carolina on 20 August 1942 as one of the four original squadrons of the 340th Bombardment Group. However, it was not until September that the squadron received its initial cadre, mostly drawn from the 309th Bombardment Group. By the end of September, it had nearly 200 assigned personnel, but it was only in November that it was fully manned. It completed Phase I and Phase II training at Columbia with North American B-25 Mitchells, then moved to Walterboro Army Air Field, South Carolina in November, where it completed Phase III training and departed for the Mediterranean Theater of Operations at the end of January 1943.
The squadron's ground echelon travelled by train to Camp Stoneman, California, where it boarded the USS West Point (AP-23) for the combat zone via the Pacific and Indian Oceans. The air echelon travelled by train to Kellogg Field, Michigan, where it received new B-25s to ferry across the Atlantic. It departed Morrison Field, Florida on 25 February 1943.

#### Combat operations

The squadron arrived at its first combat base, RAF Kabrit, Egypt in March 1943, with the air echelon arriving between 10 and 20 March and the ground echelon on 29 March. It began combat operations from Medenine Airfield, Tunisia in April, where the 340th Group flew its initial seven missions with the 12th Bombardment Group. Shortly thereafter it moved to Sfax Airfield, Tunisia and began operations on its own. The 486th engaged primarily in air support and interdiction operations, targeting airfields, roads, bridges, road junctions, supply depots and marshalling yards. It participated in Operation Corkscrew, the reduction of defenses in Pantelleria and Lampedusa in June 1943. Although the squadron's operations were hindered by primitive living conditions at its base and unfavorable weather, the squadron supported the British Eighth Army in Tunisia and Allied forces in Operation Husky, the invasion of Sicily. For these actions, it was awarded a Distinguished Unit Citation (DUC).
As the Germans evacuated from Sicily, it attacked their evacuation beaches near Messina the following month. In September, it supported Operation Avalanche, the invasion of Italy near Salerno. During the first six months of 1944, it provided air support for the Allied drive on Rome. In March 1944, Mount Vesuvius erupted, covering 340th Group aircraft at Pompeii Airfield with ash. As a result, the squadron was forced to move to Gaudo Airfield. In April, it moved to Alesani Airfield, on Corsica.
The squadron sometimes bombed strategic targets as well. It operated against factories in Albania, Austria, Bulgaria, France, Greece, Italy (including Sicily), Tunisia and Yugoslavia. After September 1944, these targets included German lines of communication, particularly in the Alps, where it conducted raids on targets in the Brenner Pass. It also engaged in psychological warfare operations, dropping propaganda leaflets behind enemy lines. The squadron received a second DUC for action on 23 September 1944. The Italian Navy was attempting to block access to the heavily defended harbor of La Spezia by sinking a cruiser to block the entrance to the harbor. The squadron attacked and sank the cruiser before it could be maneuvered into position.
Just prior to V-E Day, the squadron returned to Italy, leaving for the United States in July 1945. It arrived in August, but was inactivated in November.

### Air Force reserve

The 486th Bombardment Squadron was reactivated as a reserve unit under Air Defense Command (ADC) at Tulsa Municipal Airport, Oklahoma on 31 October 1947. It is not clear whether or not the squadron was fully staffed or equipped with operational aircraft. In 1948 Continental Air Command assumed responsibility for managing air reserve and Air National Guard units from ADC. President Truman’s reduced 1949 defense budget required reductions in the number of units in the Air Force, and the 486th was inactivated in August 1949 and not replaced as reserve flying operations at the Tulsa airport ceased.

### Strategic Air Command
#### B-47 Operations

In July 1951, Strategic Air Command (SAC) reopened Sedalia Air Force Base, Missouri, which had served as an air transport base during World War II. On 1 August, it activated the 4224th Air Base Squadron to expand the field to accommodate strategic bombers, and on 1 October 1952, the 340th Bombardment Wing, including the 486th Squadron, was activated to replace the 4224th. However, the wing concentrated is activities on bringing Sedalia to operational status and the squadron was only nominally manned, and did not become operational until 1954, when it began to receive Boeing B-47 Stratojets.
From 13 September to 3 November 1955, the squadron deployed to the United Kingdom along with the other operational elements of the 340th wing, which was attached to SAC's 7th Air Division. Starting in 1957, deployments of entire wings was replaced by Operation Reflex, which placed Stratojets and Boeing KC-97s on alert at bases closer to the Soviet Union for 90 day periods, although individuals rotated back to home bases during unit Reflex deployments After 1958, SAC's Stratojet units began to assume an alert posture at their home bases, reducing the amount of time spent on alert at overseas bases. General Thomas S. Power’s initial goal was to maintain one third of SAC's planes on fifteen minute ground alert, fully fueled and ready for combat to reduce vulnerability to a Soviet missile strike. The SAC alert commitment was increased to half the squadron's aircraft in 1962.
Soon after detection of Soviet missiles in Cuba, SAC brought all degraded and adjusted alert sorties up to full capability. It dispersed its B-47s on 22 October 1962. Most dispersal bases were civilian airfields with Air Force Reserve or Air National Guard units. B-47s were configured for execution of the Emergency War Order as soon as possible after dispersal. On 15 November 1/6 of the dispersed B-47s were recalled to their home bases. On 21 November SAC went to DEFCON 3. Dispersed B-47s and supporting tankers were recalled on 24 November. On 27 November SAC returned to normal alert posture.
In the summer of 1963, the squadron began phasing down its operations at what was now Whiteman Air Force Base in preparation for Whiteman becoming a base for LGM-30 Minuteman intercontinental ballistic missiles and the transfer of the base to the 351st Strategic Missile Wing.

#### B-52 Operations

On 1 September 1963, the squadron moved on paper to Bergstrom Air Force Base, Texas, where it assumed the mission, personnel and Boeing B-52D Stratofortresses of the 335th Bombardment Squadron, which was simultaneously inactivated. At Bergstrom it conducted global operations and maintained bombers on alert.
The squadron moved to March Air Force Base, California in October 1966 as Bergstrom was transferred from SAC to Tactical Air Command. At March, it became part of the 22d Bombardment Wing, With the transfer, the 22nd became a "super wing" with two bombardment squadrons and two air refueling squadrons. From 10 March to early October 1967, all tactical resources of the 22nd Wing, including the 486th, were deployed to other SAC organizations to support operations in Southeast Asia. The squadron continued to deploy resources and maintain some of its undeployed B-52s on alert. In December 1965, a few months after the first B-52Bs started leaving the operational inventory, Robert S. McNamara, Secretary of Defense, ordered another program to further reduce SAC’s bomber force. This program called for the mid-1971 retirement of all B-52Cs, and several subsequent B-52 models. As a result, the 486th was inactivated on 1 July 1971.
