| Description: |
|---|
| This bomb has a streamlined, one-piece, cast-steel body, with nose end open to take the exploder container. The rear end is reduced to form a spigot for taking the tail assembly. The boss on the spigot is tapped and threaded to receive the tail-securing rod. The exploder container is cemented in cemented in position, and locked by a locking screw. |
| Use: |
|---|
| There are only two sizes of fragmentation bombs now in use by the British. These are the 8-lb and several different marks of 20-lb. fragmentation bombs, including a modified U.S. 20-lb. fragmentation bomb. |
| Functioning: |
|---|
| A cylindrical strut is attached to the tail cone by four finc. The tail is secure to the body by a tail rod screwed into a boss on the body spigot, and passing through a threaded adapter on the narrow end of the tail cone. The locking nut and spring washer at both the outer and inner ends of the rod lock it in position. |
