World War I

Squadron S.E.5 at Gengault Aerodrome (Toul), France, November 1918

The first predecessor of the squadron was established as the 20th Aero Squadron in June 1917 at Camp Kelly, Texas. A few days later, due to the aforementioned clerical error, it was redesignated the 25th Aero Squadron.^[2] After the United States' entry into World War I, the squadron deployed to Europe aboard RMS Carmania, first to England, then to the Western Front in France in late October 1918. it was assigned to the 4th Pursuit Group of the Second Army Air Service in the Toul Sector, but without any airplanes. The squadron finally received some British Royal Aircraft Factory S.E.5s, mostly armed with a single fuselage-mounted Vickers machine gun, and flew two missions in November 1918 days before the war ended. The first patrol was uneventful and the other patrol targeted a truck convoy in Metz with 20 lb bombs hand-dropped from their S.E. 5a aircraft. The unit returned to the United States in the spring of 1919 and was demobilized in June.

Defense of the Panama Canal

The 25th Squadron (Bombardment) was organized on 1 October 1921 at Mitchel Field, New York, although it is not clear whether it was equipped before moving to France Field in the Panama Canal Zone in April 1922, where the Panama Canal Department assigned it to the 6th Composite Group.^[9] It flew various biplane bombers to defend the Panama Canal. In April 1924, the squadron, now the 25th Bombardment Squadron, was consolidated with the World War I unit.^[10] During the 1920s and early 1930s, it participated in various goodwill missions in Latin America, including flights to El Salvador and Nicaragua, from 13 to 19 May 1935; to Guatemala, from 8 to 11 February 1938, and again to El Salvador, from 19 to 22 April 1938. The squadron also flew mercy mission to Chile following the devastating 1939 Chillán earthquake in January and February 1939.^[10]

Squadron Martin B-10 in Panama, 1935–1940

The squadron equipped with Douglas B-18 Bolos and became the 25th Bombardment Squadron (Medium) on 6 December 1939 .^[9] The squadron had an opportunity to put its new, long-legged aircraft to the test in October 1939, when two Peruvian flyers, en route from the United States to Lima, Peru on a long-distance flight, were reported missing between the Canal Zone and Peru. Although eventually found to have made an emergency forced landing in Ecuador, three B-18s of the squadron conducted extensive searches of the area along the 80th meridian some 250 miles to sea. The aircraft carried enough fuel for a flight of 11 hours duration. On 20 November 1940, the unit became the 25th Bombardment Squadron (Heavy)^[2] in anticipation of the receipt of Boeing B-17E Flying Fortresses. By 25 August 1941, with its pre-war strength at but five B-18s, the Squadron was finally re-equipped with B-17E Flying Fortresses.

World War II

Strategic attacks on Japan

Squadron B-29 Superfortress at Chakulia Airfield, India^{[note 2]}

The 25th was stationed at Pratt Army Air Field, Kansas in July 1943 and remanned with new personnel. It received prototype and early production-model Boeing B-29 Superfortress very heavy bombers. It trained under Second Air Force for an extended period due to Boeing technicians making modifications to its B-29 aircraft. It deployed with the new XX Bomber Command as part of the 58th Bombardment Wing to the China-Burma-India Theater, flying to bases in India via South Atlantic ferrying route; across central Africa and Arabia to Karachi. Additional modifications to its B-29s were necessary in India to accommodate very high ground temperatures of 115 °F (46 °C).

From airfields in eastern India, engaged in very long range bombardment raids on Japan. The squadron participated in the first American Air Force attack on the Japanese Home Islands since the 1942 Doolittle raid on 15/16 June 1944, attacking the Imperial Iron and Steel Works at Yawata on Kyushu by using its forward staging base at Hsinching Airfield (A-1), China, for refueling.^[11] It performed a total of nine missions to Japan, also engaged in very long range attacks against enemy targets in Thailand, Manchuria, Borneo, Formosa, Burma, Malaya, Japanese-occupied China, Singapore, Saigon and Cam Rahn Bay, French Indochina. It also engaged in aerial mining of Japanese-occupied seaports in Thailand, Malaya and French Indochina.^[11]

The advance of American forces in the Central Pacific though the Northern Mariana Islands made new airfields available within the effective bombing range of Japan. It moved to West Field (Tinian) in April 1945, becoming part of the new XXI Bomber Command. From the Marianas, it engaged in very long range strategic attacks on Japan, its first mission being on 5 May 1945 against the Hiro Naval Aircraft Factory in Kure. Air attacks over Japan were initially high-altitude daylight bombing missions against industrial, transportation and military targets, largely ineffective due to high upper-level winds dispersing bombs over a wide area. By July, began low-level large area night incendiary raids on urban areas, and dropped mines in Japanese shipping lanes. Continued aerial assaults until the Japanese Capitulation in August 1945, final combat mission taking place on 9/10 August attacking the Hikari Naval Arsenal.^[11]

After V-J Day, the squadron dropped food and supplies to Allied prisoners in Japan, Korea, and Formosa, and took part in show-of-force missions. The squadron returned to the United States in November 1945 and was inactivated at Davis-Monthan Field, Arizona in the fall of 1946.^[2]

Strategic bombardment

Squadron B-47s on Smoky Hill AFB flight line in 1956

The squadron was reactivated at Smoky Hill Air Force Base, Kansasin 1952 as Strategic Air Command expanded its bomber force. The 25th initially received what were by then second-line B-29s for training and organization. The propeller-driven B-29s were replaced with new Boeing B-47E Stratojet swept-wing medium bombers in 1954, capable of flying at high subsonic speeds and primarily designed for penetrating the airspace of the Soviet Union. In the 1960s, the B-47 was considered to be reaching obsolescence and was being phased out of SAC's strategic arsenal. The 25th began sending aircraft to other B-47 wings as replacements in early 1964 and was one of the last SAC squadrons equipped with the Stratojet. The squadron inactivated in September 1964 when the last B-47 aircraft was retired from SAC.

Strategic tactics development and range control

The 25th was reactivated in 1988 as a SAC training squadron. From 1988 to 1992, the 25th supervised SAC Boeing B-52H Stratofortress bomber crew training and, from 1992 to 1995, Air Combat Command B-52H and then Rockwell B-1 Lancer bomber crew training at Ellsworth Air Force Base, South Dakota. The squadron provided range control and tactics development via the Strategic Training Route Complex from its Strategic Weapons Center facility.^[12] It inactivated again in 1995.

Space tactics development and range control

A requirement for a safe and secure space range mission was conceived by Air Force Space Command in 2001. Connecting to its strategic training range and tactics development lineage, the 25th was reactivated at Schriever Air Force Base, Colorado as the 25th Space Control Tactics Squadron, on 1 July 2004.

In November 2007, the Executioners were redesignated at as the 25th Space Range Squadron and later tested new space control tactics in a secure environment.

Air Force Reserve Command activated the 379th Space Range Squadron in April 2012 as an associate unit, joining the 25th in its range management function.^[13][14]

In 2013, the 25th was transferred back to Air Combat Command and moved under the Nevada Test and Training Range of the United States Air Force Warfare Center.^[15]

On 21 June 2017, the 25th celebrated its "Centennial Anniversary" and became one of the first Air Force units to trace its lineage over 100 years.^[1]

On 24 July 2020 the 25th Space Range Squadron was transferred to the United States Space Force and assigned to the Space Training and Readiness Delta Provisional.^[16]

On 23 August 2021, Space Training and Readiness Command was activated and on 30 August Space Delta 11 held an activation ceremony, officially aligning all Space Force range and aggressor units under a single command, including the 25th.^[17]
