|
OPERATION: |
|
Spring loaded safety plunger is depressed by adjacent bomb; upon release from cluster it jumps out leaving the firing pin riding on a creep spring. On impact the firing pin overcomes its creep spring and strikes primer, igniting the thermate which melts the steel body and releases molten iron. |
|
REMARKS: |
|
AN-M54X is the same as AN-M54 except that next to the hexagonal nose plug a small portion of the thermate charge is replaced by a steel capsule containing 170 grains of black powder which explodes and scatters the molten iron after bomb has burned about one minute. It is limited standard for the Army, obsolete for the Navy. |
|
AN-M54XA1 is the same as the AN-M54 except inside the hexagonal nose plug there is a steel cylinder containing a tetryl high explosive charge with a delay fuze and a detonator. A thin spacer of magnesium is between thermate and fuze opening of explosive cylinder. After one minute of burning the fuze is ignited, exploding the tetryl. These bombs are no longer being produced for naval service, and should not be used except when AN-M50A2 or AN-M59 bombs are not available. It is limited standard for the Army, obsolete for the Navy. |
