Aircraft Required for Ground-Air Support

SUPPORT AVIATION

I. Discussion

1. Requirements are based, on the minimum necessary to:

a.  Support the air offensive, including such ground action as required to seize and hold base areas.
b.  Training with Army Ground and Naval Forces, to include reasonable provision for Hemisphere Defense.
c.  Support combined operations in final phases.

2. Light and Dive Bombardment requirements total 35 Groups, or one Group per three Divisions for the 108 Division AGF plan. The proportion of dive bombers is larger in the Japanese theatre because of relative weakness of fighter opposition and the preponderance of naval targets. Proportions are subject to change due to present low production of level types, but this is counterbalanced by use of Medium Bombardment Groups for similar tactical functions.

3. Observation requirements are based on one squadron per Division for the 108 Division program. By retaining a smaller proportion in Hemisphere Defense and training, additional squadrons are available in theatres for Corps and Army use.

4. Troop Carrier requirements are based on minimum Troop Carrier needs in each theatre, and on intra-theatre air-borne supply. It has been assured all inter-theatre airline supply will be furnished by ATC cargo aircraft. There is thus no requirement for Transport Groups as distinguished from Troop Carrier Groups in any theatre. The Japanese theatre requirement is based on one wing in Burma, one in China, two for Australia and the island area north and east thereof, and envisages a rather large requirement for air-borne supply and movement of units.

Assuming two round trips per day, 300 mile radius of action, 75% planes in commission, and the C-47 towing one glider, one group equals 216,000 ton miles per day. One Wing carries one-half airborne division per trip or one division per day. Thus the four Wings in the Japanese Theatre could move four airborne divisions or 6,480 tons of supplies 300 miles per day.

5. Photo requirements appear high, but the efficiency of the air offensive is tremendously enhanced by intelligence photographs before and after bombardment missions.
