NOTES:

1. Of all the components required by an airplane assembly plant, the aero-engines are by far the most important. As will be seen from the table above, it is estimated that the present output of combat type aero-engines is about three thousand two hundred twenty-five (3,225) per month, which are required for the pursuit and bomber airplane assembly plants mentioned in the previous study.

2. If the seventeen (17) plants were effectively destroyed, the output of combat airplanes in Germany would be brought to a standstill.

COMPARATIVE VALUE OF TARGETS

LOCATION OF TARGETS

BOMBER FORCE REQUIRED

1. DESCRIPTION OF TARGETS

An aero engine manufacturing plant comprises an ordinary engineering works with foundry, pressing shop, machine shops, etc. However, it would not be classed as a heavy engineering works. The layout may vary from plant to plant and no average figures for site exist.

2. NUMBER OF DIRECT HITS AND TYPE OF BOMBS REQUIRED

It is considered that a weight of attack should be made upon these targets such that not less than one hundred 300-lb. bombs fall within the target area of 1000' x 1000'. Due to the fact that the component parts of the works are in some cases widely dispersed, several aiming points would be taken, each involving the weight of attack just mentioned.

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 in order to attack the whole of the 17 targets proposed with the weight of attack set out above, the total requirements will comprise:-

7,632 SORTIES

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

256 BOMBERS

must be set up.
