Operations from England

12th Tactical Reconnaissance Squadron being trained by the RAF at Membury Airfield England during World War II

In England, the squadron went through an intensive training program with the Royal Air Force. On 17 October 1942, it was assigned Spitfire PR Mk XIs, and late in January 1943, it received its first A-20 Havoc. During those months the squadron participated in several maneuvers and became a very efficient organization. On 8 July, the unit was re-designated the 12th Reconnaissance Squadron (Fighter). A little later, on 13 July, a reorganization took place and the A-20s, gunners, liaison pilots, and most of the observers of the squadron were transferred to the 153rd Liaison Squadron. The 12th was then equipped with North American P-51 Mustangs and F-6 reconnaissance Mustangs. Late in October, the 12th Squadron was transferred from the VIII Air Support Command to the IX Fighter Command. The unit became highly mobile and proficient at changing airfields on short notice. It would fly from eight English bases before moving to the Continent.^[3]

On 13 November, the squadron was re-designated again, to the 12th Tactical Reconnaissance Squadron. Although the pilots of the 12th engaged in operations against the enemy while on detached service with the Royal Air Force, it was not until 2 January 1944 that the squadron began operations as a unit when Capt James L. Rose flew its first operational mission, a weather reconnaissance over France. On 4 January, the squadron, as part of the 67th Group, was assigned to the IX Air Support Command (re-designated IX Tactical Air Command in April 1944). After its first operational mission, the 12th helped to photograph 160 miles (260 km) of French coast and two inshore strips, each 120 miles (190 km) long using the Merton Oblique camera. On 20 March, after 19 days of extremely hazardous operation, the task was completed. Eighty-three missions were flown; 18 were aborted, 14 due to weather. The maps and photographs were an important contribution to the success of Operation Overlord, the invasion of the continent of Europe. The 12th shared a Distinguished Unit Citation with the 67th Tactical Reconnaissance Group for the "most extensive low altitude oblique photographic assignment ever undertaken over enemy territory." Now the 12th TRS turned to photographing targets over Belgium and France – targets from Le Havre to Luxembourg, and from Liège to Lorient. One day it was marshalling yards in Belgium, another day bridges along the Seine River, then gun emplacements on the "Rocket Coast" plus targets in the Pas-de-Calais area. In May 1944, 66 out of 75 missions were successful.^[3]

Northern France Campaign

On 6 June 1944, D-Day, and for days afterwards, the 12th TRS performed area and route reconnaissance missions as well as artillery adjustment missions over and immediately behind the front lines. The squadron flew 250 missions during the month and operated around the clock. Reconnaissance was a major factor in allied strategy, and the 12th TRS kept higher echelons informed of enemy convoy and troop movements, and the location of troop concentrations. Effective 13 June, the 12th was transferred to the 10th Photographic Reconnaissance Group. However, about 5 July 1944, the squadron moved with the 67th Tactical Reconnaissance Group to ALG A-9 Le Molay-Littry – the first of five airfields from which it would operate in France – and began supporting the United States First Army, which was massing for a breakthrough near Saint-Lô. After the breakthrough, the 12th followed General George S. Patton's Third Army in its drive across France and supported him for the rest of the war.^[3]

On 1 August 1944, the squadron was assigned to the XIX Tactical Air Command. Since no French airfield was ready for the 10th Group, the 12th had to handle the reconnaissance load for the first several days, flying 26 missions in five days with a 100 percent success rate. Although bad weather hampered its operations during the rest of the year, several outstanding missions were flown. On the 11th, the squadron was the first from the 10th Reconnaissance Group to move onto the newly captured Rennes Airfield (A-27). During September, in addition to its regular missions, the 12th flew 170 missions in nineteen days reconnoitering the area along and beyond the Siegfried Line where German armies were building up reserves. The pilots also spotted and photographed areas the Germans were strengthening and reconnoitered marshalling yards to see if reinforcements were being sent in from other parts of Germany. During November and December, missions were flown over the Ruhr and Rhine valleys and over such cities as Frankfurt, Mannheim, Wiesbaden, Koblenz, and Ludwigshafen, many of which were heavily defended.^[3]

During the German retreat after the Battle of the Bulge, the 12th kept its planes in the air, spotting enemy vehicles, troops, and supplies. Medium bombers had knocked out so many roads and bridges that thousands of German vehicles were trying to escape, but had no way to move. On 26 January, 12th TRS pilots spotted 4,000 vehicles and called in P-47 Thunderbolt fighter-bombers in to finish the job. The 12th Squadron was commended by Generals Carl Spaatz and Weyland for its work during the German withdrawal.^[3]

Invasion of Germany

The 12th moved to Vogelsang Airfield (Y-61), Germany on 2 March 1945. During March, 320 missions were flown in support of the Third Army's break through of the Siegfried Line. At this point, the squadron received an order stressing the fact that the 12th was a reconnaissance squadron and that engagements with the enemy should not be encouraged. Reconnaissance areas changed rapidly in keeping pace with Patton. During the first part of April, targets included Frankfurt, Darmstadt, Würzburg, and Kassel. Later they were farther east – Gotha, Erfurt, Leipzig, and Chemnitz. Then the 12th moved south to Munich, Regensburg, and Nuremberg, and it finished the month by making long flights (with wing tanks) into Austria and Czechoslovakia, reconnoitering Prague, Pilsen, Linz, and Vienna. Although hostilities in general ceased in Europe on 7 May 1945, the 12th Squadron continued to fly photographic missions in support of Allied forces in Czechoslovakia, where the fighting did not stop until 10 May.^[3]

The 12th Tactical Reconnaissance Squadron made a very impressive record during World War II. The unit's historian reported that 2,732 missions were flown, 26 enemy planes destroyed, three probably destroyed, and ten damaged. The 12th Squadron lost nine planes. After the war, the 12th became part of the occupation air force in Europe. It remained at Fürth Airfield, Germany, assigned to the 10th Reconnaissance Group of the XII Tactical Air Command. The squadron demobilized during late 1945 and early 1946, being reduced to an administrative unit. On 12 February 1946 it moved to Bolling Field, Washington DC where it was inactivated on 31 March 1946.^[3]

Postwar Era

The squadron was reactivated at March Field, California on 31 August 1946 as the 12th Reconnaissance Squadron, Photo (Jet Propelled). It was assigned to the 363d Reconnaissance Group, Ninth Air Force. However, because the rest of the group was stationed at Brooks Field, Texas, and later at Langley Field, Virginia, it was attached to Twelfth Air Force. The squadron, receiving FP-80 Shooting Star aircraft, claimed to be the first unit in the Air Force to use jet-photo equipment. Extensive aerial photography was performed by the 12th, including maps and layouts for the United States Department of Agriculture, the Army Corps of Engineers, and many other agencies. On 24 July 1947, the 12th was reassigned once again to the 67th Reconnaissance Group, and in the months that followed, the 12th participated in many exercises and maneuvers. The squadron filled many requests for aerial photographs. Many layouts of dams and waterways were made for the Army Corps of Engineers, Army Mapping Service, and the Department of Agriculture's Soil Conservation Service^[3]

Korean War

On 5 February 1951, the unit was re-designated the 12th Tactical Reconnaissance Squadron, Night Photo. On 25 February, eight months after the Korean War started, it was activated at Komaki Air Base, Japan, and assigned to the 67th Group once more. The 67th was part of the 67th Tactical Reconnaissance Wing, which had been formed in a reorganization of reconnaissance assets in Fifth Air Force. Personnel and equipment (RB-26s) came from the inactivated 162d Tactical Reconnaissance Squadron which returned to the United States. On 15 March 1951, the unit moved to Taegu Air Base (K-2), South Korea, where the operations section had been located since the first part of the month. The primary mission of the squadron during the Korean War was to provide the night reconnaissance capability for the wing, both photographic and visual. During hours of darkness, the 12th Squadron was tasked to collect information on enemy activities, to make visual searches and perform route reconnaissance, to perform targeting, and bomb damage assessments, to determine the accuracy of SHORAN coordinates. In emergencies, the 12th was expected to assist the two-day visual and photo recon squadrons.^[3]

In March 1951, the squadron's first month in South Korea, the 12th flew a total of 256 effective sorties. One of its early tasks was to provide photographs of all enemy airfields in North Korea. It also flew sorties in conjunction with the preparation and execution of a parachute drop on 23 March. On 21 August, the squadron moved to Kimpo Air Base (K-14) at Seoul and remained there for the remainder of the war. The equipment complement of the 12th Squadron necessarily influenced its performance of mission. The squadron was authorized 27 RB-26 Invaders for night reconnaissance missions, but it seldom possessed so many planes and several of the authorized aircraft were EB-26s modified for electronic reconnaissance. In the summer of 1953, the RB-26s covered the three main supply routes of the enemy each night: one route on each coast and one in the center of the peninsula. Special night photo missions were also flown against pre-briefed targets at which some particular enemy activity, was suspected on occasions the night photo planes photographed targets that for some reason could not be covered during daylight.^[3]

During the period 1 January to 30 June 1953, the unit's pilots flew 1,117 missions and sighted 88,795 enemy vehicles. In July, the last months of the war, the 12th flew 334 missions, including several daylight runs. Aerial reconnaissance seems to have been of even greater importance in the Korean fighting than in any previous war. According to a survey made shortly after hostilities ceased, air reconnaissance accounted for a considerable part of all intelligence used by ground units and for a high percentage used by the United Nations air forces.^[3]

Service in Japan

Following the end of the Korean War, the 12th TRS continued to operate from Kimpo until 8 November 1954, when it moved to Itami Air Base, Japan. The 12th maintained at least one RB-26 and crew on temporary duty at Kimpo until 28 July 1956 to provide the U.S. Army and the Republic of Korea Army with photo reconnaissance of South Korea and the demilitarized zone.^[3]

On 14 August 1956, the squadron moved from Itami to Yokota Air Base, which could accommodate the twin jet Douglas RB-66B Destroyers with which the 12th was soon to be equipped. The 12th was the first squadron in Pacific Air Forces to receive the RB-66B.^[4] On 22 December the first of the 12th's new planes arrived. In April 1958, two of the 12th's aircraft deployed to Bangkok, Thailand, to fly reconnaissance missions for a Southeast Asia Treaty Organization (SEATO) exercise, and in the following June its RB-66s took part in a joint Navy-Air Force exercise, providing navigational aid and escort for F-100Ds attacking the naval task force.^[3]

During January 1960, crews of the 12th ferried their planes to the United States, refueling from tankers over Wake Island and Hawaii. Not long after, on 8 March, the squadron was inactivated at Yokota.^[3]

Vietnam War

On 3 November 1965, the outfit was redesignated the 12th Tactical Reconnaissance Squadron (Photographic) and assigned to Tactical Air Command. It was reactivated at Mountain Home Air Force Base, Idaho on 1 July 1966, and organized there about 8 July, assigned again (temporarily) to the 67th Wing. At this time the unit was equipped with McDonnell RF-4C Phantom II reconnaissance aircraft. On 2 September of that year, the unit deployed to Tan Son Nhut Air Base, Republic of Vietnam, where it became a part of the 460th Tactical Reconnaissance Wing on 9 September.^[3]

In the first four full months of operation in Southeast Asia, crews of the 12th TRS flew 2,014 combat sorties against pinpoint, strip, and area cover targets in North Vietnam, South Vietnam, and Laos. Approximately two-thirds of these were flown at night. Continuous information on enemy supply movements, troop concentrations, and fortifications was obtained from aerial photography taken by the 12th. In addition, photography taken by the unit was used in bomb damage assessment, base defense planning, and enemy air defense site detection. The 12th flew more than 26,000 combat sorties and 53,000 hours over a 5-year period. This was more than in both World Wars and Korea combined.^[3]

Post-Vietnam

The 12th Tactical Reconnaissance Squadron moved to Bergstrom AFB, Texas, on 20 August 1971, where it became – once again – a component of the 67th Tactical Reconnaissance Wing. The unit made annual Salty Bee exercise deployments to USAFE bases in Europe, participated in exercises throughout North America, and was actively involved in the Peacetime Aerial Reconnaissance Program (PARPRO). Modifications to the RF-4C added the capability to designated targets for laser guided munitions. Crews and aircraft from the 12th deployed to the Middle East to take part in Operation Desert Storm in 1991. On 28 August 1992 with the retirement of the RF-4C Phantom, the 12th Tactical Reconnaissance Squadron was inactivated at Bergstrom AFB, Texas.^[3]

Twenty-first century

Reactivated at Beale Air Force Base, California in 2001 operating RQ-4 Global Hawk remotely piloted aerial reconnaissance aircraft as part of the Global War on Terror. In March 2013, the squadron was reassigned to the reactivated 69th Reconnaissance Group as part of the consolidation of the USAF Global Hawk mission.^[5] In June 2019 the squadron was reassigned to reactivated 319th Operations Group.^[6] The 12th Reconnaissance Squadron still operates from Beale Air Force Base in California.
