Description
The body is a sheet-steel casing extending the entire length of the bomb. The tail cup fits into the after end of the casing, having a dome housing the Fuze M1. The bomb does not have a device for stabilization in flight; therefore, an all-ways fuze is employed.
Once the arming pin jumps out, the fuze is armed, and any attempt to reinsert the pin may cause the fuze to function.
Functioning
As the bombs are released from the cluster, the arming pin is forced out by its spring, permitting the safety pin to enter the cavity in the striker. Impact forces the striker and sleeve together, piercing the primer, which in turn ignites the first fire mixture and subsequently the HC smoke mixture. The heat generated by the burning of the first mixture and the HC smoke mixture melts the zine-alloy fuze body. The smoke is then emitted through the fuze hole in the tail cup.
