World War II

B-18 as flown by the squadron

The squadron was activated at Langley Field, Virginia in January 1941 as the 18th Bombardment Squadron, one of the original squadrons of the 34th Bombardment Group, and equipped with a mixture of B-17C and B-17D Flying Fortresses and Douglas B-18 Bolos. Along with the 34th Group, the squadron moved to Westover Field, Massachusetts four months after they were activated.^[3][5]

After the Pearl Harbor attack the squadron began antisubmarine patrols off the Northeast coast of the United States, but soon became part of Western Defense Command and moved to Pendleton Field, Oregon. By the summer of 1942, Second Air Force had become primarily a heavy bomber training force and the squadron became a B-17 Replacement Training Unit (RTU) at Geiger Field.^[5] RTUs were oversized units which trained aircrews prior to their deployment to combat theaters.^[6]

On 15 December 1942 the squadron moved to Blythe Army Air Base, California a base of the Desert Training Center.^[7] The unit provided cadres for a number of heavy bomber units that served with Eighth Air Force during this period.^[8]

B-24H of the 34th Bomb Group^{[note 4]}

The 18th began training with Consolidated B-24 Liberators for overseas combat operations on 5 January 1944. Its ground echelon moved to the port of embarkation on 1 April 1944,^[5][8] while the air echelon began its overseas movement on 31 May 1944, taking the southern ferry route, from Florida to Trinidad, Brazil, West Africa and Marrakesh arriving at RAF Valley, Wales.^[8] The squadron arrived at its permanent station, RAF Mendlesham, England, in April 1944 and entered combat on 23 May 1944.^[5][8]

The squadron helped to prepare for Operation Overlord, the invasion of Normandy, by bombing airfields in France and Germany, and supported the June landings by attacking coastal defenses and communications. It supported ground forces at Saint-Lô in late July and struck V-1 flying bomb launch sites, gun emplacements, and supply lines throughout the summer of 1944.^[5]

34th Bomb Group B-17G Flying Fortress^{[note 5]}

The mixture of B-24s and B-17s in the 3d Bombardment Division presented a number of operational problems, and in early 1944 plans had begun at VIII Bomber Command headquarters to standardize the division with the Flying Fortress.^[9] The 34th Group flew its last B-24 mission on 24 August 1944.^[8] It transferred its Liberators for overhaul and eventual transfer to units of the 2d Bombardment Division,^[10] and began converting to B-17s. It flew its first mission with the new planes on 17 September 1944.^[5][8] The squadron engaged primarily in bombardment of strategic objectives from October 1944 to February 1945. Targets included marshaling yards in Ludwigshafen, Hamm, Osnabrück, and Darmstadt; oil centers in Bielefeld, Merseburg, Hamburg, and Misburg; factories in Berlin, Dalteln, and Hanover; and airfields in Münster, Neumünster, and Frankfurt.^[5]

During this period the squadron also supported ground forces during the Battle of the Bulge from December 1944 to January 1945. In March 1945, with few enemy industrial targets remaining and with Allied armies advancing across Germany, the 18th turned almost solely to interdicting enemy communications and supporting Allied ground forces.^[5] The 18th flew its last combat mission on 20 April 1945.^[8]

After V-E Day the squadron flew missions carrying food to flooded areas of the Netherlands and transported prisoners of war from German camps to Allied centers. The squadron redeployed to the United States in June and July 1945.^[5] The first elements of the air echelon departed 19 June 1945. The ground echelon sailed aboard the RMS Queen Elizabeth from Southampton on 6 August 1945. Upon arrival in the states, unit personnel were given 30 days leave.^[8] The squadron reassembled at Sioux Falls Army Air Field, South Dakota, where it was inactivated on 28 August 1945.^[5]

Vietnam War

AC-119 Stinger

The second predecessor of the squadron was activated as the 18th Special Operations Squadron on 25 January 1969 at Lockbourne Air Force Base, Ohio, and deployed to Phan Rang Air Base, South Vietnam, the 18th SOS flew the Fairchild AC-119K Stinger gunship. The squadron's primary mission was the interdiction of enemy supply lines, close air support, and air base defense. Following the transfer of the aircraft to the Republic of Vietnam Air Force, the 18th was inactivated 31 December 1972.

Test and evaluation

On 1 October 1983, the Special Missions Operations Test and Evaluation Center (SMOTEC) was activated at Hurlburt Field by order of the Secretary of the Air Force as a direct reporting unit of Headquarters Military Airlift Command at Scott Air Force Base.^[11] SMOTEC was formed through the consolidation of the test and evaluation function previously assigned to the 1550th Aircrew Training and Test Wing, located at Kirtland Air Force Base, New Mexico, which was responsible for combat rescue and related test. It was also responsible for the informal test and evaluation staffs of the 2d Air Division and the 1st Special Operations Wing, at Hurlburt Field. Though testing was reassigned to SMOTEC in October 1983, most of the testing continued at Kirtland for the remainder of that year.^[4]

SMOTEC explored new special operations capabilities and developed better equipment and tactics to support Air Force special operations forces. It provided AFSOC with the centralized expertise for development and operational testing of new systems and tactics, proposed changes in doctrine, and recommended new requirements. The unit's colocation with the 1st Special Operations Wing made it ideally suited to perform the mission of improving the worldwide Air Force aim of special operations forces.

SMOTEC remained a direct reporting unit to Headquarters AFSOC until 31 March 1994. On 1 April 1994, it was inactivated and its assets, personnel, and equipment were "reflagged" as the 18th Flight Test Squadron, also a direct reporting unit to AFSOC.
