Organization of the 6th Bomb Group

The 6th Bomb Group was part of the 313th Bombardment Wing of the 21st Bomber Command of the 20th Air Force. The 20th Air Force was the first Air Force not put under the command of a Theater Commander, such as Eisenhower, McArthur or Nimitz. Instead, General Curtis LeMay assumed direct command of the 20th Air Force. The mission of the 20th was to engage in the strategic destruction of Japan by air.

The 6th Bomb Group played a significant role in winning the war against Japan. This was due not only to the bravery of the air crews, but to the tireless efforts of the folks on the ground. It is significant that both of the Distinguished Unit Citations mention not only the risks involved in the missions, but the critical role played by the ground personnel. In the month of July, when all eyes were focused on the War in the Pacific, the 6th Bomb group led the Wing in hours flown and tonnage dropped, both in total and per aircraft. This kind of success required a constant, coordinated and dedicated effort by every member of the Group.

The 20th Air Force was originally intended to include several Bomber Commands, based in several locations: the 20th (based in India), the 21st (based in the Marianas), the 22nd (based in the Philippines or Formosa) and the 23rd (based in the Aleutians). 1 The Marianas proved to be the best location. The 22nd and 23rd Bomber Commands were never activated. The 20th Bomber Command was activated in 1943 and included the 58th Bombardment Wing. However, operations out of China proved impractical since all supply was from the air. The 20th Bomber Command was eventually deactivated and all Bombardment Wings were assigned to the 21st Bomber Command.

The 21st Bomber Command included the 58th, 73rd, 313th, 314th and 315th Bombardment Wings. (For a full listing, see the Table at the bottom of this page). The 313th Bombardment Wing included the 6th, 9th, 504th, 505th Bomb Groups and, later, the 313th Composite Squadron (the “Atom Bombers”). The 6th Bomb Group included the 24th, 39th and 40th Bombing Squadrons. The 313th Bombardment Wing also included several Service Groups (probably the 72nd, 77th, 358th and 359th Service Groups). The 6th Bomb Group also includes several Service Squadrons.





Each Bomb Group was supported by an Air Service Group (ASG), which handled the big repair and maintenance jobs. Each ASG included a Headquarters and Base Services Unit (HQ), an Air Engineering Squadron (AE), and an Air Material Squadron (AM). The 6th Bomb Group was supported by the 72nd ASG, which included the 535th AE and the 579th AM. They were located on the northeast corner of North Field. Most of the personnel in the ASG were formerly members the 6th BG. They were assigned to the ASG in an effort to centralize the maintenance function. The 72nd ASG included the following units:

  • Headquarters and Base Services Unit
  • 535th Air Engineering Squadron
  • 579th Air Material Squadron
Other B-29 Groups and Wings were located on Tinian, Saipan and Guam. They were all part of the 21st Bomber Command of the 20th Air Force. The 58th Bombardment Wing was originally part of the 20th Bomber Wing, which was deactivated in March 1945.
