721st Tactical Fighter Squadron

The 721st Tactical Fighter Squadron is an inactive United States Air Force unit. It was last assigned to the 450th Tactical Fighter Wing at Foster Air Force Base, Texas, where it was inactivated on 18 December 1958.

The squadron was first activated as the 721st Bombardment Squadron in 1943. After training with Consolidated B-24 Liberators in the United States, it deployed to the Mediterranean Theater of Operations, where it participated in the strategic bombing campaign against Germany, earning two Distinguished Unit Citations. After V-E Day, the squadron returned to the United States and briefly trained with Boeing B-29 Superfortresses but it was inactivated following Japan's surrender.

The squadron was reactivated in 1954 as the 721st Fighter-Bomber Squadron at Foster, where it was initially equipped with North American F-86 Sabres. The following year, it became one of the first units to equip with the North American F-100 Super Sabre. It continued to fly the "Hun" until it was inactivated when Foster closed.

Training in the United States
The squadron was first activated as the 721st Bombardment Squadron at Gowen Field, Idaho on 1 May 1943 as one of the four original squadrons of the 450th Bombardment Group. It soon moved to Clovis Army Air Field, New Mexico, where it was manned, drawing its cadre from the 302d Bombardment Group. and began to train with Consolidated B-24 Liberators. A cadre of the squadron was sent to the Army Air Forces School of Applied Tactics in June, where it received advanced heavy bomber tactical training. In November 1943, the 721st began moving overseas. The ground echelon proceeded to the port of embarkation at Camp Patrick Henry, sailing on the SS Bret Harte, while the aircrews staged at Herington Army Air Field, Kansas, and ferried their planes to the Mediterranean Theater of Operations via the South Atlantic Ferry Route.

Combat operations
The squadron arrived at its combat station, Manduria Airfield, Italy, in early January 1944 and began engaging in the strategic bombing campaign against Germany, primarily striking targets in Austria, Czechoslovakia, France, Germany, Hungary, Italy, and the Balkans. The squadron's first mission was flown against Mostar Airfield, Yugoslavia on 8 January. Targets included aircraft factories and assembly plants, oil refineries, marshalling yards, airfields and storage areas. Shortly after arriving in theater, the squadron participated in Big Week, attacking aircraft factories at Regensburg, Germany and Steyr, Austria. It was awarded a Distinguished Unit Citation (DUC) for its attack on the Messerschmitt factory at Regensburg on 25 February, despite bad weather, heavy flak in the target area and enroute attacks by enemy interceptor aircraft. The 450th Group led the 47th Bombardment Wing on the attack. The 721st earned a second DUC for an attack on rail yards near Ploesti on 5 April, when it fought its way through "relentless" attacks by enemy aircraft to reach the target. The rail yards were a vital link in the transportation of petroleum products from the Ploesti refineries to the eastern front. The 450th Group again led the 47th Wing on this mission.

During the spring of 1944, the squadron flew missions for Operation Strangle, the effort to choke off supplies for Axis military in Italy through air interdiction. The squadron also supported Operation Dragoon, the invasion of southern France in September 1944 by attacking troop concentrations, lines of communications and enemy coastal defenses. In addition, it conducted missions to support the Red Army advance through the Balkans and Allied advances in Italy.

The squadron returned to the United States in May 1945, assembling at Sioux Falls Army Air Field, South Dakota at the end of the month. It moved to Harvard Army Air Field, Nebraska in July and trained with the Boeing B-29 Superfortress, however after V-J Day in August the squadron inactivated on 15 October.

Fighter operations
The squadron was redesignated the 721st Fighter-Bomber Squadron and activated at Foster Air Force Base, Texas in July 1954 under Tactical Air Command. The squadron initially flew North American F-86 Sabre fighters, but soon converted to the North American F-100 Super Sabre. In March 1955, the squadron was renamed the 721st Fighter-Day Squadron to reflect the F-100's air superiority capabilities. In July, the squadron's parent 450th Fighter-Day Wing became the first wing to equip with the improved F-100C model of the "Hun." In November 1957, the 450th Wing converted to the dual deputy organization. The 450th Fighter-Day Group was inactivated, and the squadron was assigned directly to the wing, reporting to a deputy commander for operations. Starting in July 1958, the squadron began to phase down in anticipation of its inactivation and the closure of Foster. It was inactivated on 18 December 1958.
