NOTES:

1. A successful attack on this type of target is required to reduce production to zero for a period of about two (2) months. Thus, if all fifteen (15) targets were dealt with, the effect would be to reduce the output by about one thousand (1000) airplanes, after which production would return to normal and further attacks would become necessary on these or new locations.

2. Successful attacks on the first seven (7) plants is likely to reduce production by 62.6 percent.

COMPARATIVE VALUE OF TARGETS

LOCATION OF TARGETS

BOMBER FORCE REQUIRED

1. DESCRIPTION OF TARGETS

An airplane assembly plant usually comprises a series of several buildings, fairly widely dispersed around a factory airfield. These buildings comprise Assembly Sheds, Flight Hangars, Stores, Administrative Buildings, Canteen, etc. The total ground area of these buildings in the case of these particular targets varies from 600,000 to 1,600,000 square feet. A careful examination of the various plants indicates that the vital portions of the target are about 2 to 6 main assembly sheds, each about 400' x 400' (320,000 to 960,000 square feet total area).

2. NUMBER OF DIRECT HITS AND TYPE OF BOMBS REQUIRED

It is considered that at least six (6) direct hits are required on each of the main sheds to cause effective destruction. The buildings and jigs are of comparatively light construction and it is considered that 300 lb. bombs will be required.

3. NUMBER OF SORTIES AND BOMBER FORCE REQUIRED

Based upon detailed calculations taking into account all operational factors involved in making attacks against highly defended targets with appropriate allowances for probabilities, aiming errors, losses, etc., etc., it appears that a total of 2,808 sorties would be required to attack each target once. Due to the rapidity with which these assembly sheds and jigs can be rebuilt, it is considered necessary to repeat the attacks at Intervals of two months. In the period of six months, therefore, three (3) attacks are required on each plant giving a total of:-

9,424 SORTIES

In order to carry out these sorties in 35 operational days, a force of:-

284 BOMBERS

must be set up.
