The 423d Bombardment Squadron is an inactive United States Air Force unit. Its last assignment was with the 306th Bombardment Wing at MacDill Air Force Base, Florida.

The squadron was first activated as the 34th Reconnaissance Squadron in the spring of 1942, but was soon renamed the 423d Bombardment Squadron, one of the original four squadrons assigned to the 306th Bombardment Group. After training with Boeing B-17 Flying Fortresses, the squadron moved overseas and participated in the strategic bombing campaign against Germany, earning two Distinguished Unit Citations for its efforts. After the war the 423d remained in Europe with the occupation forces until inactivating in 1946.

The squadron was activated again at Langley Air Force Base, Virginia and served as a combat crew training squadron for aircrews flying the Douglas B-26 Invader. It was inactivated in 1954 when the 345th Bombardment Group became the tactical bomber unit at Langley.

The third active period for the unit began in 1959 when Strategic Air Command (SAC) expanded its Boeing B-47 Stratojet wings from three to four squadrons. It flew the Stratojet until 1962 when SAC alert commitments changed and Stratojet wings returned to a three squadron structure.

The squadron was first established in March 1942 at Gowen Field, Idaho as the 34th Reconnaissance Squadron, one of the original four squadrons of the 306th Bombardment Group.^[3][4] In April, its personnel moved to Wendover Field, Utah, where it began training with Boeing B-17 Flying Fortress heavy bombers and was redesignated as the 423d Bombardment Squadron.^[1] On 1 August 1942, the squadron's ground echelon began its deployment, spending a week at Richmond Army Air Base, Virginia before moving to Fort Dix, New Jersey at the Port of Embarkation. It sailed on the RMS Queen Elizabeth on 30 August, arriving in Scotland on 5 September 1942. The air echelon departed for Westover Field, Massachusetts, and began ferrying their B-17s to England via the North Atlantic ferrying route.^[4][5]

The squadron settled into its combat station, RAF Thurleigh, England, in early September. Although several bomber units arrived in England before the 423d, when these units left England to participate in Operation Torch it became, along with its companion squadrons of the 306th Group, the oldest bombardment squadrons of VIII Bomber Command. It few its first combat mission on 9 October 1942 against a steel factory near Lille, France, but with poor results. This was the first mission on which VIII Bomber Command assembled a strike force of over 100 bombers.^[5][6][b] The squadron operated primarily against strategic targets, including the locomotive factory at Lille, marshalling yards at Rouen, France, and Stuttgart, Germany. The squadron took part in the first strike into Germany by bombers of Eighth Air Force on 27 January 1943 when it struck U-boat yards at Wilhelmshaven. It struck shipbuilding yards at Vegesack, ball bearing plants at Schweinfurt, the aircraft factory at Leipzig, Germany, and similar facilities.^[4]

On 1 May 1943 the aircraft in which Staff Sergeant Maynard Smith was a gunner was struck by enemy fire, igniting fires in the plane's radio compartment and waist. Sgt Smith threw exploding ammunition overboard, extinguished the fire, administered first aid to the wounded tail gunner and manned his gun until enemy fighter aircraft were driven off. Sgt Smith was awarded the Medal of Honor for his actions on this mission.^[4]

On 11 January 1944, the squadron participated in an attack on an aircraft plant in central Germany, near Brunswick. Extensive cloud cover had resulted in the recall of two of the three bombardment divisions involved in the mission and made the rendezvous of the fighter groups scheduled to provide cover in the target area difficult. In contrast, clear weather to the east of the target permitted the Germans to assemble one of the largest fighter formations since October 1943, with 207 enemy fighters making contact with the strike force.^[7] For this mission, the squadron was awarded the Distinguished Unit Citation (DUC). The following month the squadron earned a second DUC for its performance during Big Week, an intensive bombing campaign against the German aircraft industry. Despite adverse weather on 22 February that led supporting elements to abandon the mission the squadron and group effectively bombed the aircraft assembly plant at Bernburg, Germany.^[4]

The squadron also performed in a tactical role, assisting ground forces Operation Cobra, the St Lo breakthrough, Operation Market Garden, the attempt to establish a bridgehead across the Rhine near Arnhem in the Netherlands, stopping German attacking forces in the Battle of the Bulge, and bombing enemy positions during Operation Varsity, the airborne assault across the Rhine in the spring of 1945.^[4]

After V-E Day, the squadron became part of the occupation forces and participated in Project Casey Jones, the photographic mapping of portions of Europe and North Africa.^[4] When the 306th Group began to phase out of the project in July the squadron was attached to the 305th Bombardment Group. Toward the end of 1946 responsibility for the unfinished portion of the project was transferred to XII Tactical Air Command.^[8] In February 1946, the squadron moved to Istres-Le Tubé Air Base, France, where it absorbed elements of the inactivating 92d and 384th Bombardment Groups, returning to Germany in July.^[5] The squadron was inactivated in December 1946.^[1]

During and immediately after the Korean War, Tactical Air Command (TAC) trained aircrews for the Douglas B-26 Invader at Langley Air Force Base, Virginia. The three squadrons of the 4400th Combat Crew Training Group performing this mission were Air National Guard units that had been mobilized for the war. At the start of 1953, these squadrons were returned to state control and the 423d was activated^[1] and took over the mission, personnel, and equipment of the 117th Bombardment Squadron, which returned to the Pennsylvania Air National Guard.^[9] In January 1954, the group mission shifted to tactical bombardment and it was redesignated the 4400th Bombardment Group. As the group began to anticipate the transition to Martin B-57 Canberra aircraft, TAC decided to replace the Table of Distribution 4400th Group and its squadrons with the regular 345th Bombardment Group, which took over their mission in July 1954^[10] and the 423d was inactivated.^[1]

The squadron was activated for a third time in 1959 as Strategic Air Command (SAC)'s Boeing B-47 Stratojet fleet reached a peak of twenty-seven wings^[11] From 1958, the Boeing B-47 Stratojet wings of SAC had assumed an alert posture at their home bases, reducing the amount of time spent on alert at overseas bases. The SAC alert cycle divided itself into four parts: planning, flying, alert and rest to meet General Thomas S. Power's initial goal of maintaining 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.^[12] To implement this new system B-47 wings reorganized from three to four squadrons.^[12][13] The 423d was activated at MacDill Air Force Base, Florida as the fourth squadron of the 306th Bombardment Wing.^[1] The alert commitment was increased to half the squadron's aircraft in 1962 and the four squadron pattern no longer met the alert cycle commitment, so the squadron was inactivated on 1 January 1962.^[1][13]
