US Bomb, 250 lb Fire, BLU-10/B, BLU-10A/B
The BLU-10/B and the BLU-10A/B 250 pound antipersonnel and materiel bombs are smaller versions of the BLU-1/B. In addition, they have an initiator adapter which is designed to prevent napalm from leaking into the initiator well. Otherwise, the bombs are similar to the BLU-1/B and are assembled and stored in the same manner. The bomb consists of three major sections: the nose, the center, and the tail, which are nested with the supplemental components to obtain a high density package.
The BLU-10A/B bomb has an extended open type hard back. Otherwise it is identical to the BLU-10/B bomb.
