Bombardment group

Abombardment grouporbomb groupwas a unit of organizational command and controlgroupof theUnited States Army Air Forces(USAAF) duringWorld War II.A bombardment group was normally commanded by acolonel.The table of allowances (TOA) for personnel, aircraft and equipment grew steadily over the course of the war doubling from 35 aircraft in 1941 to 72 in February, 1945. The aircrew end strength reached upwards to two crews per aircraft.

Categories

U.S. bomb groups were numbered and classified into four types: Very Heavy (VH), Heavy (H), Medium (M), and Light (L). Groups which combined bombers of differing categories into a single administrative organization were designated "Composite" groups. Bomber aircraft were assigned to groups by category:

(The USAAF also operated two fighter-bombers during the period, theA-24and theA-36.Groups with these two types were first classified as Light Bombers, then Dive Bombers, before being re-classified as Fighters.)

Tables of organization and equipment

Unit organization

edit

Thetables of organization and equipment(TO&E) for all bombardment groups were roughly the same. In 1942, existing bomb groups were expanded from three to fournumbered bombardment squadrons;and most bomb groups created during the war retained this structure - B-29 groups were the exception, having only three squadrons. In addition to the flying squadrons issuedAircrew Badges,each group contained agroup headquarters,aservice squadron,anddetachmentsfor support of aircraft, equipment, and personnel fromquartermaster,aviation ordnance,military police,chemical,signal,and maintenance companies, and from a weather squadron. These support personnel were then pooled and re-distributed among an unofficial service group and detailed for various duties as needed.

The service group provided support and technical sections for the group requirements as a whole:Flying control,Ordnance,airfield security,firefighting,Post Exchange(PX),Special Services,Mail,Transportation( "motor pool"),Communications,Radar,Gunneryinstruction,Personal Equipment,andWeather(Meteorology). The service group also had its ownmesssection. The service group had approximately 30 officers and 300 to 400 enlisted men.

The group headquarters contained sections organized in the traditionalU.S. Armystructure: Personnel (S-1), Intelligence (S-2), Operations (S-3), and Supply (S-4). Including inspectors, headquarters organizations in practice totalled approximately 20 officers, some of whom were alsopilots,and 60 to 80 enlisted men.

Each bomb squadron, in addition to its assigned flight crews, had asquadron headquartersstructured similarly to the group's, and six technical support and maintenance sections supporting its aircraft, equipment, and personnel:Mess,Armament,Ordnance,Communications,Medical,andEngineering(aircraft maintenance). The ground support members of a bomb squadron numbered 15-20 officers and 250 to 300 enlisted men.

Functionally, bomb groups were divided into anair echelon(the collective aircrews), and aground echelon(all supporting ground personnel within the group, including those in attached Sub Depots). Groups commonly had two deputy commanders, termed the airexecutive officerand the ground executive officer, to coordinate these echelons.

Personnel strengths

edit

In 1943, a heavy bomb group had a total complement of 294 officers and 1,487 enlisted men to fly and support 48 heavy bombers; and a medium bomb group had 294 officers and 1,297 enlisted men for 64 medium bombers.

By February 1945, the size of the 125 standardized bomb group establishments had grown to:

AAF Bombardment group organization
March 1945
Type of unit Type of aircraft Number of aircraft Number of crews Men per crew Total personnel Officers Enlisted
Very heavy bombardment group B-29 45 60 11 2,278 462 1,816
Heavy bombardment group B-17, B-24 72 96 9 - 11 2,261 465 1,796
Medium bombardment group B-25, B-26 96 96 5 - 6 1,759 393 1,386
Light bombardment group A-20, A-26 96 96 3 - 4 1,304 211 1,093

The Army Air Forces also employed two composite groups with their own TO&Es: the 28th Bomb Group (15 B-24 and 30 B-25), and the509th Composite Group(15 B-29 and 5 C-54). 19 heavy groups and one light bomb group were to be converted to very heavy groups for duty againstJapan,but the war ended before the plan was carried out.
