World War II 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. 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 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. 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. ==Lineage==
