FUZING: |
|
AN-M110A1 |
|
BOMB CONSTRUCTION: |
|
The bomb is made from a seamless steel tubing, with an ogival nose threaded to receive the nose fuze. A burster well tube runs the entire length of the body, fitting into a positioning cup at the rear. The tail assembly consists of four fins welded to a sleeve, which is secured by a locking nut threading into the tail closing block. The fins are supported by box-type struts. |
|
SUSPENSION: |
|
The bomb is carried horizontally by dual lugs 7 inches on either side of the cen-ter of gravity, or a single lug 180° removed at the center of gravity. |
|
A cluster of four M70's is formed by using the M22 (T9) cluster adapter. |
|
REMARKS: |
|
On impact the fuze funcitons instantaneously, setting off the burster charge which explodes the bomb and scatters the main filling. |
|
The M70 can be filled with white phosphorous (WP), IM or NP incendiary mix. |
