The 509th Composite Group was an air combat unit of the United States Army Air Forces during the Second World War and as the 509th Operations Group, is a current unit of the United States Air Force. It was tasked with developing and employing a combat delivery system for the Atomic bomb and conducted the attacks on Hiroshima and Nagasaki, Japan, in August 1945.

The group later became a medium bombardment group of the Strategic Air Command, as the combat component of the 509th Bomb Wing, before being inactivated in 1952. Its lineage, honors, and history were also bestowed on the like-numbered wing in 1947.

After more than forty years of inactivation, the group was activated again as part of the 509th Bomb Wing and designated the 509th Operations Group, conducting the combat and training operations of the B-2 Spirit bomber.

Component support organizations


Special Mission 16, Secondary target Nagasaki, August 9, 1945 [Campbell, "The Silverplate Bombers", 32.]

While the Nagasaki mission was in progress, two B-29's of the 509th took off from Tinian to return to Wendover. Lt.Col. Classen, the deputy group commander, in the unnamed victor 94 and crew B-6 in "Jabit III", together with their ground crews, were sent back to stage for the possibility of transporting further bomb assemblies to Tinian. [Campbell, "The Silverplate Bombers", 195.] However the plutonium cores were still at Site Y, and on August 13 Gen. Groves ordered that all shipments of material be stopped. His order reached Los Alamos in time to keep the third bomb from being shipped. [Campbell, "The Silverplate Bombers", 39.] The first Atomic War lasted 9 days, August 6 through August 15, 1945.

After the Nagasaki mission the group continued combat operations, making another series of pumpkin bomb attacks (12 dropped) on August 14. With the announcement of the Japanese surrender, however, the 509th CG flew three further training missions involving 31 sorties on August 18, 20, and 22, then stood down from operations. The group flew a total of 210 operational sorties from June 30 to August 22, and aborted four additional flights, with only one aircraft failure to take off. 140 involved the dropping of live ordnance. [Campbell, "The Silverplate Bombers", 26.] 62 sorties received combat credits for missions flown (49 pumpkin bomb and 13 atomic bomb sorties). [Campbell, "The Silverplate Bombers", 104.]

Post-World War II history

In November 1945 the 509th Composite Group left Tinian and relocated to Roswell Army Air Field, New Mexico. The eight Silverplate bombers that had been delivered to Wendover in August also joined the group. Col. William H. Blanchard replaced Col. Tibbets as group commander on January 22, 1946, and also became the first commander of the 509th Bomb Wing.

The Group was assigned to Strategic Air Command on March 21, 1946, being one of the first eleven organizations assigned to SAC. At the time SAC was formed, the 509th Composite Group was the only unit to have experience with nuclear weapons and thus is regarded by many historians as the foundation on which SAC was built. In April 1946 many of the group's aircraft deployed to Kwajalein as part of Operation Crossroads, a series of atomic bomb tests. The remainder became the core of two new squadrons activated as part of the group, the 715th Bomb Squadron and the 830th Bomb Squadron.

On July 10, 1946, the group was renamed the 509th Bombardment Group (Very Heavy) and the 320th TCS was disbanded. With the creation of the United States Air Force as a separate service, the group became the combat component of the 509th Bomb Wing on November 17, 1947, although it was not operational until September 14, 1948, when Col. John D. Ryan was named commander.

The group was redesignated as a medium bomb group in 1948 as part of the Strategic Air Command, and acquired an aerial refueling mission with the assignment of KB-29s. Its 27 operational Silverplate B-29s (the 309th had ultimately received 53 of the 65 produced) were transferred in 1949 to the 97th Bomb Wing at Biggs Air Force Base, El Paso, Texas, when the group converted to B-50 Superfortresses.

Its squadrons were removed on February 1, 1951, and assigned directly to the wing, effectively ending its operations. The 509th was inactivated on June 16, 1952 as part of a SAC (and later Air Force-wide) phase-out of groups.

Honors

Department of the Air Force Special Order GB-294, dated 2 September 1999, awarded the Air Force Outstanding Unit Award (with Valor) to the 509th Composite Group for outstanding achievement in combat for the period 1 July 1945 to 14 August 1945. [Campbell, "The Silverplate Bombers", 221, Chapter 8 note 8.]

Insignia

In addition to the official insignia the 509th Bomb Wing for B-2 stealth bomber test flights, based in Roswell, New Mexico, sported an informal insignia involving an alien, the legend "To Serve Man" (referring to a famous Twilight Zone episode) and the legend "Gustatus Similis Pullus" or "Tastes Like Chicken" (referring to the possible taste of long pig).
