Bomber B-52H Stratofortress

The 2d Operations Group (2 OG) is the flying component of the United States Air Force 2d Bomb Wing, assigned to the Air Force Global Strike Command Eighth Air Force. The group is stationed at Barksdale Air Force Base, Louisiana.

2 OG is one of two Air Force Global Strike Command groups to fly the B-52H Stratofortess. Its mission is to protect the United States and further its global interests by providing devastating combat capability.

The group is a successor organization to 2d Bombardment Group, one of the 15 original combat air groups formed by the Army before World War II. It is the oldest bomb group of the Air Force, having fought on the Western Front during World War I, entering combat on 12 September 1918. After the war, it participated in Brigadier General Billy Mitchell's 1921 off-shore bombing test. During World War II the group engaged in combat from bases in North Africa and Italy flying B-17 Flying Fortress.

In the postwar era, the 2d Bombardment Group was one of the first USAAF units assigned to the Strategic Air Command on 1 July 1947, prior to the establishment of the United States Air Force. Equipped with low-hour B-29 Superfortress surplus World War II aircraft, the group was inactivated in 1952 when the parent wing adopted the Tri-Deputate organization and assigned all of the groups squadrons directly to the wing.

Reactivated as the 2d Operations Group in 1991 when the 2d Bomb Wing adopted the USAF Objective organization plan.


The 2 OG (Tail Code: LA) consists of the following squadrons:

World War I

Organized as the 1st Day Bombardment Group as part of the Air Service, United States First Army on 10 September 1918 at Amanty Airdrome, France. The group consisted of the 96th Aero Squadron, which had been operating independently and was equipped with French Breguet 14 B.2 bombers. Three other squadrons, the 11th, 20th and 166th Aero Squadrons were equipped with American-Bult De Haviland DH-4s.[1] The group completed its organization and began operations on 12 September, however only the 96th, 11th and 20th had received its aircraft at the opening of the St. Mihiel Offensive. Due to its experience, the 96th Squadron was the most effective in combat operations, however the other three squadrons also achieved a high degree of efficiency, gaining experience attacking troop concentrations and communications to interfere with the enemy's movement of reinforcements and supplies to the front. Other patrols of the group were flown by conducting bombing operations that helped to protect Allied ground forces by diverting German pursuit planes from the battle zone.[1]

The initial attack by the group on 13 September sent five aircraft of the 96th Squadron to Chambley, but only three managed to cross into enemy territory. They were attacked by fifteen Enemy Aircraft and they approached their objective, which shot down two group aircraft. The objective was successfully bombed, however, and two enemy aircraft were shot down. The first full group action took place the next day with three missions being performed. The railway yards at Conflans-en-Jarnisy, Vittonville and Arnaville were all attacked, along with secondary attacks at Étain and Dommary-Baroncourt. Nine enemy aircraft were encountered in combat, shooting down one near Mars la Tour. The 11th lost a plane near Chambley.[1]

During the offensive large concentrations of enemy aircraft were encountered, giving formidable resistance and great losses due to attempting penetrations of enemy air space with small formations and without protection from pursuit aircraft. On 23 September, operation were moved to Maulan Aerodrome, and on 26 September, Dun-sur-Meuse was attacked by both Bregut and DH-4 Squadrons in the morning, and Etain by the DH-4s in the afternoon.[1]

On 9 October 1918, it participated in one of the largest bombing raids of the war, when 353 Allied planes commanded by Gen. Billy Mitchell struck German troop concentrations in the Meuse-Argonne area where German troops were preparing for a counterattack against the Allied offensive.[1]

The final bombardment mission of the group took place on 5 November when three formations of DH-4s were dispatched to raid Mousson and Roucourt, Belgium in the morning. Planes from the 11th Squadron failed to cross the lines, however the others reached their assigned objective and at Mouzon, where the weather permitted observation, accurate bomb hits and many fires, with a large number of explosions were noted. Enemy aircraft resistance was strong, with the 20th being attacked by three formations of Fokkers, some with four machine guns, rather than the normal two mounted in front. The 20th managed to shoot down four of the enemy, however, lost three aircraft of their own in the combat. During the remaining days of the war, the 1st Day Bombardment Group was on alert, however bad weather prevented any combat operations from taking place.[1]

In more than two months of combat, the group delivered more than 111 tons of bombs on German targets. Demobilized in France in November 1918, soon after the armistice.

Interwar years

On 18 September 1919, at Kelly Field, Texas, the group was re-organized and formally established as part of the Air Service. On 31 March 1921, the 1st Day Bombardment Group was re-designated the 2d Group (Bombardment), and on 25 January 1923, as the 2d Bombardment Group.

From 13 to 21 July 1921, the 2d Group’s four bombardment squadrons were detached to General Mitchell’s 1st Provisional Air Brigade to conduct controversial tests to determine the efficiency of aircraft against naval warships. The aircraft successfully bombed and sank three ex-German warships, including the formidable 22,437-ton battleship Ostfriesland, off Cape Hatteras, North Carolina. From 23 to 26 September 1921, the group’s bombardment squadrons, again under the direction of General Mitchell, bombed and sank the ex-Navy battleship USS Alabama (BB-8) in yet another test of aircraft bombardment efficiency.

On 1 July 1922, the 2d Bomb Group relocated to Langley Field, Virginia, where it would remain for the next twenty years. On 5 September 1923, the group, operating from an improvised aerodrome on the sands near Cape Hatteras, N.C., bombed and sank the ex-Navy battleships USS Virginia (BB-13) and USS New Jersey (BB-16).

To further attest the group’s capabilities, three 97th Bombardment Squadron Martin B-10B aircraft commanded by Capt. Richard E. Nugent departed Langley Field, Va., and successfully bombed a target 600 miles away in Michigan during the Second Army Maneuvers. This mission, flown almost entirely in inclement weather, garnered the squadron the 1936 Mackay Trophy.

On 4 March 1937, the group received the first of 12 B-17 Flying Fortresses delivered to the U.S. Army Air Corps. A goodwill tour to Argentina by six B-17s in February 1938 and a flight to Colombia by three B-17s in August of the same year highlighted the late 1930s. The trip to Buenos Aires represented the longest distance performance of its kind on record and won the group the Mackay Trophy in 1938. A second MacKay trophy was won in February of the following year when a crew flew medical supplies aboard the XB-15 to Chile following a catastrophic earthquake.

The group also achieved a well-publicized success on 12 May 1938, when three B-17s, led by group commander Lt. Col. Robert Olds and navigated by 1st Lt. Curtis E. LeMay, intercepted the Italian ocean liner Rex over 600 miles at sea during a training exercise.

On 6 December 1939, the group was redesignated the 2d Bombardment Group (Heavy).

World War II

Served on antisubmarine duty for several months after the U.S. entered World War II. In October 1942 was re-designated as 2d Bombardment Group (Heavy) and earmarked for combat. The group was transferred on paper to Geiger Field, Washington, where it was re-organized and trained with new personnel.

The group was made up of four Squadrons, the 20th, 49th, 96th, and the 429th. In November 1942, the squadrons were sent to satellite bases in Montana for additional training as units, the 20th to Great Falls, the 49th to Lewistown, the 96th to Glasgow, and the 429th to Cut Bank. This was the third and final phase of training.

The 2d Bomb Group and squadrons left their satellite bases on 13–14 March 1943 arriving at Camp Kilmer, New Jersey 17–18 March 1943 for debarkation overseas. The Flight Echelon left the above bases for Morrison Field West Palm Beach, Florida; Natal, Brazil; Marrakech, Morocco and arriving at Navarin, Algeria on 22 April 1943. The Ground Echelon were disbursed at Camp Kilmer in several ships arriving at Casablanca and Port Lyautey in March/April 1943, thence motor and train convoy to Navarin, Algeria. Was initially assigned to Twelfth Air Force.

It arrived at Chateau D'un, Algeria on 27 April 1943. The first mission on 28 April 1943 was to Terranova, Sardinia. The 2d Bomb Group departed Chateau D'un after flying 25 missions and arrived at Ain M'Lila, Algeria on 17 June 1943 and flew 25 missions from that base. The 2d Bomb Group departed for Massicault, Tunisia on 31 July 1943 and flew 56 missions from that base.

Missions flown included bombing such targets as marshalling yards, airdromes, troop concentrations, bridges, docks, and shipping. Participated in the defeat of Axis forces in Tunisia, April–May 1943; the reduction of Pantelleria and the preparations for the invasion of Sicily, May–July 1943; and the invasion of Italy, September 1943.

Moved to Italy in December 1943 and continued operations as part of Fifteenth Air Force. Operated primarily from Amendola Air Base in Foggia. Engaged primarily in long-range bombardment of strategic targets in Germany, Poland, Czechoslovakia, Austria, Hungary, Yugoslavia, Rumania, and Greece. Participated in the drive toward Rome, January–June 1944; the invasion of Southern France, August 1944, and the campaigns against German forces in northern Italy, June 1944 – May 1945. En route to bomb an aircraft factory at Steyr, Austria on 24 February 1944, the group was greatly outnumbered by enemy interceptors, but it maintained its formation and bombed the target, receiving a Distinguished Unit Citation (DUC) for the performance. On the following day, while on a mission to attack aircraft factories at Regensburg, it met similar opposition equally well and was awarded a second DUC.

Served as part of the occupation force in Italy after V-E Day. Inactivated in Italy on 28 February 1946. Group gunners claimed 279 victories of German and Italian aircraft. Flew 406 combat missions; 146 aircraft lost.

Cold War

On 1 July 1947, the group was redesignated the 2d Bomb Group (Very Heavy) and activated at Davis Monthan Field, Arizona. Equipped with B-29 Superfortress bombers, the 2d BG became part of the Strategic Air Command. Trained for bombardment missions and deployed to England, August–November 1948 and February–May 1950. On 10 February 1951 the group became a "paper organization" with its squadron components attached directly to the 2 Bombardment Wing as part of the Air Force tri-deputate reorganization. Inactivated on 16 June 1952.

The group was reactivated in on 1 September 1991 as the 2d Operations Group and assigned to the 2d Wing as part of the "Objective Wing" concept adapted by the Air Force. 2 OG took control of the wings bomber and refueling squadrons upon activation.

Trained for global conventional bombardment missions as well as maintaining nuclear operational readiness. Briefly controlled the wing's air refueling mission until it transferred to Air Mobility Command. Provided combat crew training for all USAF B-52 aircrews, beginning November 1994. In response to Saddam Hussein's attacks against the Kurdish minority in northern Iraq, aircrews of the 96th Bomb Sq deployed and launched attacks against military targets in Iraq in September 1996, actions for which the aircrews received the Mackay trophy as the most meritorious flight of 1996. Continued to deploy aircraft and personnel to southwest Asia to support the Allied watch on the southern and northern "no-fly" zones in Iraq. Flew combat missions against targets in Iraq, 17–18 December 1998, in response to Iraq's refusal to allow UN weapons inspectors to continue work. Flew combat missions against targets in Yugoslavia, 24 March – 9 June 1999, in support of NATO Operation Allied Force. In October 1999 began deploying personnel in support of aerospace expeditionary forces worldwide and maintaining on-call elements at home.

Global War on Terrorism

After the terrorist attacks against the U.S. on 11 September 2001, group elements, including the 20 Bomb Sq, deployed to the island of Diego Garcia in the Indian Ocean. On 7 October flew early attacks on targets in Afghanistan in Operation Enduring Freedom to rid that country of terrorist bases and its extremist Taliban rulers. Later flew airborne alert missions over Afghanistan and in Operation Anaconda, flew bombing missions against targets in eastern Afghanistan, 1–18 March 2002. In the invasion of Iraq beginning March 2003, flew missions on 21 March in "shock and awe" strikes against command and control targets. Provided bomber combat power and expeditionary combat support for warfighters, 2004–2006.
