Body construction: This bomb is constructed of cast-steel nose and tail pieces, a seamless steel inner tube, and a helically-wrapped drawn steel wire wrapping around the inner tube. The tube is threaded to hold the nose and tail sections. |
|
Suspension: For individual suspension of this bomb, a U-shaped eyebolt of steel is welded to the body at the center of gravity for horizontal suspension, and an eyebolt is welded to the tail for vertical suspension. |
|
The bomb may be dropped in a cluster of six bombs in the Cluster Adapter AN-M1A2 or M1, forming the Cluster AN-M1A1 or M1. The cluster adapter is made of sheet steel, and does not use eyebolts of bombs for suspension. |
|
Tail construction: Four rectangular sheet-steel vanes are welded to a length of one-inch cast-iron pipe which screws into the base filling plug. |
|
Remarks: This bomb is a high-level fragmentation bomb and should be dropped from a minimum altitude of 400 feet. |
|
The A1 modification of this bomb consists of adding a 1½-inch shoulder around the nose to facilitate clustering with unfuzed bombs. Heretofore, the spacers of the cluster adapter have fitted against the fuze, thereby making it requisite that the bombs be clus-tered and shipped with fuzes inserted. |
