The 55th Operations Group, ACC's largest group, located at Offutt Air Force Base, Nebraska, has operational control over 12 squadrons and two detachments worldwide. The group consists of approximately 3,200 personnel.
The group's mission is to provide worldwide reconnaissance, real-time intelligence, command and control, information warfare and combat support to U.S. leaders and commanders.
It employs 46 aircraft, including 13 models of seven different types. Mission responsibility includes the Air Force's most diverse flying operations supporting worldwide reconnaissance, command and control, Presidential support, and nuclear treaty verification.
The 55th Operations Group uses the tail code OF for its aircraft
The 55th Operations Group traces its lineage to the 55th Pursuit (Interceptor) Group during World War II. During the war, the 55th Pursuit Group garnered two Distinguished Unit Citations. The group fostered 16 aces who were credited with 90 air-to-air victories.
After the war, Strategic Air Command activated and redesignated the 55th Fighter Group as the 55th Reconnaissance group at MacDill Field, Florida, operating the RB-17. The newly activated group's mission consisted of aerial photography, mapping, charting, and photo reconnaissance missions, some of which flew around the globe.
Activated after the end of the Cold War, the 55th Operations Group has maintained an unmatched operational tempo, supporting every US contingency worldwide.
The history of the Fightin’ Fifty-Fifth began in January 1941, when the 55th Pursuit Group was activated at Hamilton Field, California. Training along the west coast, the group move to England, August- September 1943 and was assigned to VIII Fighter Command.
The 55th FG began operations with Lockheed P-38H Lightnings on 15 October 1943, and was the first to use these aircraft on long-range escort missions from the UK. The P-38H differed from earlier versions in being powered by 1425 hp Allison V-1710-89/91 engines.
The Lightnings' engines were troubled by the addition of alcohol used as an anti-knock compound in their fuel supply; a British war economy solution which caused problems with water condensation on the ground and fuel line icing at altitude. Another British attempt to correct fuel composition caused lead metal deposits to coat cylinders and foul plugs throughout the squadron. The -H series Lightnings did not have adequate cooling for extended high-power usage, as their engine development had outstripped the cooling capacity of the integral intercooler which ran through the wing's leading edge. Pilots were instructed to restrict their periods of highest engine power to defined time limits, but many did not. As a result of these various influences, the Group's Lightnings suffered a high rate of attrition. Nevertheless, 55FG P-38H pilots provided cover for missions against aircraft plants during Big Week in February 1944. Lt. Col. Jack Jenkins led the group on 3 March 1944, when they became the first Allied fighters to reach Berlin on an escort mission.[1]
On 16 April 1944 the group moved to RAF Wormingford to accommodate the arrival of the 398th Bomb Group. The 55FG converted to North American P-51D Mustangs in July 1944, continuing their primary task of escorting B-17 and B-24 bombers that attacked such targets as industries and marshalling yards in Germany, and airfields and V-weapon sites in France. In July the group attacked gun emplacements during the Saint-Lô breakthrough in July 1944, and transportation facilities during the Battle of the Bulge, December 1944 – January 1945. The group also patrolled the air over the English Channel and bombed bridges in the Tours area during the invasion of the Continent in June 1944. The unit patrolled the Arnhem sector to support the airborne invasion of Holland in September 1944 along with strafing trucks, locomotives, and oil depots near Wesel when the Allies crossed the Rhine in March 1945.
The unit received a Distinguished Unit Citation for eight missions to Germany between 3 and 13 September 1944 when the group not only destroyed enemy fighters in the air to protect the bombers it was escorting, but also descended to low levels, in spite of intense anti-aircraft fire, to strafe airfields and to destroy enemy aircraft on the ground. Received second DUC for operations on 19 February 1945 when the organization flew a sweep over Germany to hit railway tracks, locomotives, oil cars, goods wagons, troop cars, buildings, and military vehicles. The 55th Flew last combat mission on 21 April 1945.
The 55th Fighter Group moved to AAF Station Kaufbeuren Germany on 22 July 1945 as part of the occupation forces. It was assigned to United States Air Forces in Europe. While on occupation duty, the group was one of the units to receive the first U.S. operational jet fighter, the Lockheed P-80B Shooting Star in July 1946. However, the Group continued to fly P-51s and according to. one source, A-26s. On 29 April, the unit moved to AAF Station Giebelstadt, Germany, and on 20 August 1946, the unit was inactivated, the resources being transferred to the 31st Fighter Group.
With more than 600 combat missions, the group destroyed over 400 enemy aircraft while damaging more than 100. The 55th, inactivated in August 1946, had 16 aces credited with 90 victories.
On 24 February 1947, Strategic Air Command activated and redesignated the 55th Fighter Group as the 55th Reconnaissance group at MacDill Field, Florida, operating the RB-17. The newly activated group's mission consisted of aerial photography, mapping, charting, and photo reconnaissance missions, some of which flew around the globe. RB-17s were specifically used by the 55th RG to probe the borders of the Soviet Union, who had by then begun to emerge as a potential threat to the Western Powers. Little was known about the air defence capability of the Soviet Union at this time and the most effective way of determining their capability was to probe the borders and see whether they would respond. Gradually the RB-17s and other aircraft mapped the perimeter of the Soviet Air Defences from the Baltic to the Sea of Okhotsk, north of Japan.

The group then converted to RB-29s and transferred to Topeka (later Forbes) AFB, Kansas, in 1948, but was again inactivated in October 1949. On 1 November 1950, the 55th Strategic reconnaissance group was activated as a "paper organization" with the tactical squadrons attached directly to the 55th Strategic Reconnaissance wing. The wing was bestowed with the awards and honors of the 55th Reconnaissance Group and moved to Ramey AFB, Puerto Rico. In 1952 the group was again inactivated on 16 June 1952 as the Air Force reorganized its wings into the tri-deputate system.
The group was reactivated in on 29 August 1991 as the 55th Operations Group and assigned to the 55th Wing. It was activated on 1 September 1991. The 55th OG was the operational component of the wing under the new "Objective Wing" concept adapted by the Air Force, and was bestowed the history and honors of the 55th 55 Strategic Reconnaissance Group. The 55th Operations Group activated with one of the largest and most diverse missions in the USAF.
The 24th Reconnaissance Squadron at Eareckson AFB, Shemya, Alaska, joined the group with its Cobra Eye and Cobra Ball missions.
On 1 April 1993, the 55th OG Wing took operational control of the 11th Airlift Flight. The 11 ALF flew operational airlift missions in support of the commander of the United States Strategic Command and transported high-ranking military, Department of Defense officials, and members of Congress. This unit has since inactivated and the mission has reverted back to Air Mobility Command.
The 2 ACCS also inactivated in 1994 with its mission transferring to the 7th Airborne Command and Control Squadron. Likewise, the 24 RS inactivated in 1994 and its mission transferred to the newly activated 45th Reconnaissance Squadron. Also in 1994, the 1 ACCS National Emergency Airborne Command Post was renamed the National Airborne Operations Center to reflect the addition of a support role to the Federal Emergency Management Agency.
In October 1998, the 55th OG transferred control of the Boeing EC-135 Looking Glass mission to the United States Navy's E-6B Mercury TACAMO aircraft and the 7th Airborne Command and Control Squadron, which flew the Looking Glass aircraft, inactivated. In September 1999, the 338th Combat Training Squadron was activated and assigned to the 55th Operations Group.
Additionally, in March 2000, the group received its 16 RIVET JOINT aircraft. The group conducts operations from Offutt AFB, Nebraska; Kadena AB, Japan; RAF Mildenhall, United Kingdom; Souda Bay Naval Support Activity, Crete; and other locations around the world. The 55th OG is the largest Operations Group in Air Combat Command and the second largest in the Air Force.
Since the end of the Cold War, the 55th Operations Group has maintained an unmatched operational tempo, supporting every US contingency worldwide. These missions have included but were not limited to reconnaissance, command and control, and airlift missions supporting Operations SOUTHERN WATCH, PROVIDE COMFORT, VIGILANT WARRIOR (Southwest Asia), PROVIDE PROMISE, DENY FLIGHT (Bosnia-Herzegovina), SUPPORT DEMOCRACY, UPHOLD DEMOCRACY (Haiti), and TIGER RESCUE (Yemen). Additionally, its squadrons have been called upon to support Distinguished Visitor airlift for the National Command Authorities, the Federal Emergency Management Agency, and numerous exercises.
