NOTES TO TABLE 47

The above table, taken from AirPac sources, shows the carrier ordnance expenditures for individual operations and groups of operations during 1944.

The most significant characteristic of the ordnance data, when so arranged, is the relatively high expenditure of small bombs during short operations, and the greater expenditure of heavy bombs during extended operations or the later phases thereof (including (a) the Truk and Marianas strikes which were the second phase of the Marshalls operation, (b) the Second Truk strikes which were the second phase of the Hollandia operation, (c) the Marianas operation as a whole, and (d) the Philippines strikes of September which succeeded the Palau operations). The reason for this was principally early exhaustion by some carriers of the limited allowances of small bombs; this required substitution, in the latter phases of the operation, of the large bombs which were carried in excess of reasonable needs, and these were then used regardless of the requirements of the targets. This situation was corrected in 1945 by altering the carrier allowances in favor of small bombs, and by replenishing bombs at sea during extended operations.
