It was activated in February 2018 as a geographically separate unit to operate unmanned aerial vehicles and is assigned to the 432d Wing, which is located at Creech Air Force Base, Nevada.

The first 25th Bombardment Group performed anti-submarine warfare missions in the Caribbean Sea following the entry of the United States into World War II.

Later in 1944 the second 25th Bombardment Group was organized to perform weather and special reconnaissance missions from England during World War II for United States Strategic Air Forces over Europe and the Atlantic approaches to the British Isles.

[4] In late October 1940, the 25th sailed on the USAT Hunter Liggett for Borinquen Field, Puerto Rico, along with the newly-organized 13th Composite Wing.

[5][6] Partly due to the dispersal of its units, the 12th Squadron was under the operational control of the Antilles Air Task Force from November 1942 and the 10th was reassigned to VI Bomber Command in 1943.

[18] Squadron bombers on these long range missions, code named Sharon and Allah, took periodic meteorological readings at altitudes varying from 50 to 30,000 feet.

[22] The group also performed post-strike visual reconnaissance and prestrike electronic warfare, distributing chaff ahead of attacking formations.

[18][23] The squadron also had three Martin B-26 Marauders for Joker missions and two Douglas A-26 Invaders assigned for special operations with the Office of Strategic Services.

[22][g] Following VE Day in July 1945, the group and the 654th Bombardment Squadron left the European Theater of Operations for the United States.

Although the 19th and 42d had been flying the Destroyer before joining the 25th, major construction projects were needed to accommodate their modified bombers, since Chambley had previously hosted fighter units.

The closing of American bases in Morocco deprived the wing of suitable ranges where flash bombs could be used for night photographic reconnaissance training.

[28] The movement of B-66s to the combat theater resulted in the inactivation of the 42d Squadron in August 1966 and the transfer of the majority of its aircraft and a large proportion of its aircrews to Takhli Royal Thai Air Force Base, where they were assigned to the 432d Tactical Reconnaissance Wing.

[29] The impact of the need for reconnaissance assets in Southeast Asia and limitations on training on the wing's continued existence was compounded by French President Charles De Gaulle's March 1966 announcement that France was withdrawing from the NATO Military Command Structure.

[1] Its remaining support personnel were transferred to the 7367th Tactical Group, which managed US Air Force operations at Chambley until they terminated in April 1967.

It remained inactive until 2 October 2018, when it was redesignated the 25th Attack Group and activated at Shaw Air Force Base, South Carolina.
