World War I

Inter-War period

Remained as part of the Air Service, moved to Ellington Field, Texas in July 1919 and was reformed with new personnel. Participated in demonstrations of effectiveness of aerial bombardment on warships, June–September 1921; mercy mission in relief of marooned inhabitants of islands in the frozen Chesapeake, 9–11 February 1936.^[5]

Began its association with testing when it received the first of the five Boeing YB-9, first all-metal monoplane bomber aircraft designed for the United States Army Air Corps, on 14 September 1932. The new bomber proved impossible to intercept during air exercises in May 1932, strengthening calls for improved air defense warning systems. Received the first of 12 Boeing B-17 Flying Fortresses delivered to the U.S. Army Air Corps. Participated in good-will flights to Argentina, 15–27 February 1938, Colombia, 3–12 August 1938, Mexico, 9–15 June 1939, and Brazil, 10–28 November 1939. The trip to Buenos Aires represented the longest distance performance of its kind on record and won the 2nd Bombardment Group the Mackay Trophy in 1938. Following 24 January 1939 Chillán earthquake in Chile, the XB-15, a prototype aircraft that had been assigned to the squadron to test the feasibility of operating very heavy bombers, flew a relief mission carrying medical supplies. Commanded by Major Caleb V. Haynes, the aircraft carried 3,250 lb (1,470 kg) of American Red Cross emergency supplies to Santiago, making only two stops along the way, at France Field in the Panama Canal Zone, and at Lima, Peru. Haynes was awarded the Distinguished Flying Cross and the Order of the Merit of Chile, and the whole crew earned the MacKay Trophy.^[6]

The squadron also achieved a well-publicized success on 12 May 1938, when three squadron B-17s, led by group commander Lt. Col. Robert Olds and navigated by 1st Lt. Curtis E. LeMay, a member of the 49th, intercepted the Italian ocean liner Rex over 600 miles at sea during a training exercise.^[5]

World War II

This B-17G was the lead aircraft for the 49th Bombardment Squadron from 23 July 1944 until VE-Day^{[note 5]}

During the early stages of the Second World War, the squadron conducted anti-submarine operations on both the Pacific and Atlantic coast prior to being sent to the Mediterranean Theater of Operations. From 28 April 1943 to 1 May 1945, the 49th conducted air operations in both the Mediterranean and European theaters as part of the 2nd Bombardment Group, 5th Bombardment Wing, Fifteenth Air Force stationed at Navarin Airfield, Algeria, flying the Boeing B-17 Flying Fortress. During 1943, the group moved five times: to Chateaudun-du-Rhumel Airfield, Algeria; Ain M'lila Airfield, Algeria; Massicault Airfield, Tunisia; Bizerte, Tunisia; Amendola Airfield, Italy.

Some of the important missions the 49th participated in were: the monastery at Monte Cassino, Italy, on 15 February 1944; enemy troop concentrations at Anzio beachhead on 2 March 1944; and the oil refineries at Ploiești, Romania, throughout the spring of 1944. The last mission was flown on 1 May 1945 against marshalling yards at Salzburg, Austria. On 29 October 1945, the group finally moved to Foggia Airfield, Italy, where it remained as part of the occupation forces and was inactivated on 28 February 1946. By the time the 49th was inactivated, it participated in 412 combat missions flown over Africa, France, Germany, Italy, Austria, Bulgaria, Yugoslavia, Romania, and Hungary.^[5]

Strategic Air Command

The 49th was reactivated on 1 July 1947 at Andrews Field, Maryland. The squadron soon moved to Davis–Monthan Field, Arizona, and received training on the Boeing B-29 Superfortress as part of the new Strategic Air Command long-range strike force. The 49th's first deployment came on 9 August through 16 November 1948 to RAF Lakenheath, England. Upon returning home, the 49th moved to Chatham Air Force Base, Georgia, and added the Boeing B-50 Superfortress to their inventory. In September 1950, the squadron moved to Hunter Air Force Base, Georgia and began flying training missions over the eastern half of the United States. For the next three years the 49th deployed to RAF Mildenhall and RAF Upper Heyford, England, in support of NATO exercises and RAF bombing competitions. Then in February 1954, the squadron entered the "jet age" by receiving the Boeing B-47 Stratojet. Shortly after achieving combat-ready status, aircrews began performing alert and deploying abroad. Overseas deployments included: Sidi Slimane Air Base and Nouasseur Air Base, Morocco; RAF Brize Norton, England; and three different bases throughout Spain. Not only were crews and aircraft performing alert at home, but at various overseas deployment bases also. The alert commitment at home was discontinued with the increase of deployed aircrews and aircraft. Most overseas alert tours would last from three to four weeks compared to the one-week tour alert crews performed during the height of the Cold War. The 49th returned home to perform alert duties during the Cuban Missile Crisis of 1962 before moving to Barksdale Air Force Base, Louisiana. On 1 April 1963, the squadron was inactivated until 1986.^[5]

In July 1972, the 4201st Test Squadron was activated with a new mission to conduct operational test and evaluation (OT&E) of the Short Range Attack Missile AGM-69 SRAM. To establish continuing capability for conducting MAJCOM-directed OT&E of strategic airborne weapon systems, the 4201st was designated as a permanent organization in July 1974.

At this time, the present location of Barksdale AFB, Louisiana, was established for the squadron to conduct its mission. As part of SAC's initiative to provide combat-rich histories to relatively new organizations, the 4201st was inactivated and replaced by the 49th Test Squadron in July 1986.^[5]

Post Cold War

May 2019 saw the 49th Test and Evaluation Squadron deploy a B-52H to Joint Base Pearl Harbor-Hickam for a demonstration of Quickstrike-ER (QS-ER) naval mines on the Pacific Missile Range Facility, Hawaii. The QS-ER combines Joint Direct Attack Munitions (JDAM) technology and an additional wing kit and battery section with existing mine components. The combination of which allows the QS-ER to be delivered long range and high altitudes.

The 49th Test and Evaluation Squadron is also involved in the testing of the ADM-160 Miniature Air-Launched Decoy-X (MALD-X) missile and the Conventional Rotary Launcher (CRL)^[7] integration of precision‐guided munitions.^[8]
