Following V-E Day, the squadron moved to Brazil, where it became part of Air Transport Command, returning troops to the United States before it was inactivated on 26 September 1945.

[1][5] The squadron completed its deployment to Spinazzola Airfield, Italy by the middle of February 1944, and entered the strategic bombing campaign against Germany the following month, with an attack on a marshalling yard and docks at Metković, Yugoslavia.

[7] It attacked oil refineries and storage facilities, railroads, industrial areas, including aircraft manufacturing plants in Austria, Czechoslovakia, France, Germany, Greece, Hungary, Italy, Romania and Yugoslavia.

[5] On 26 July 1944, the squadron was part of a 460th Group formation that led the 55th Bombardment Wing on an attack against an airfield and aircraft manufacturing plant at Zwolfaxing, Austria.

In August 1944, it supported Operation Dragoon, the invasion of southern France by attacking submarine pens, marshalling yards and artillery batteries in the area of the amphibious landings.

It struck lines of communications, railroads, ammunition dumps and other targets in connection with Operation Grapeshot, the allied offensive in Northern Italy.

[7] After V-E Day, the 460th Group and its squadrons were transferred to the South Atlantic Division, Air Transport Command, moving to Parnamirim Field, near Natal, Brazil to participate in the Green Project.

Green Project was aimed at transporting 50,000 military personnel a month from the European and Mediterranean Theaters back to the United States, with priority for those that plans called for redeploying to the Pacific.

[2] 9th airmen flew the Bell P-39 Airacobra, as well as the Consolidated F-7 Liberator, Boeing F-9 Flying Fortress, and Boeing F-13 Superfortress bombers retrofitted to perform photographic reconnaissance performing mapping missions over occupied Japan, Korea, Okinawa, Indochina, and other areas under Far East Air Forces' control after World War II.

[11] In January 1956, the squadron was the first in the Air Force to receive jet powered Douglas RB-66B Destroyers, which added weather sampling capability.

[citation needed] In 1969, the 9th moved to Bergstrom Air Force Base, Texas, where it became part of the 75th Tactical Reconnaissance Wing and flew McDonnell RF-4 Phantom IIs.

In 1999, Captain Patrick Assayag led a team to discuss the possibility of activating a reserve squadron to support the 614th Space Operations Flight.
