FUZING: M1 |
Hexagonal case with a nose cup welded to the forward end. The nose cup, fuze and powder charge are sealed off from the rest of the case by an impact diaphragm and plug held in a cup-shaped sealing diaphragm. The incendiary oil filling is held in a cheesecloth sack situated between the forward sealing diaphragm and the tail cup. |
TAIL CONSTRUCTION: |
Tail assembly consists of a tail cup, tail retainer and disc. The tail cup is secured to the hexagonal case by beading, crimping and heating. Four gauze streamers, each 114 inches long, are attached to the tail retainer by tail disc to stabilize the bomb and reduce the terminal velocity. |

OPERATION: |
Spring loaded safety plunger jumps out of M1 fuze upon release from cluster ar-ming fuze. On impact the striker overcomes spring, detonates primer cap, which ignites a lead-coated spitter fuze. The spitter fuze burns from 3 - 5 seconds, allow-ing penetration, and ignites black powder booster charge. This ignites the igniter-ejector charge consisting of 2 bags of black powder and oiled magnesium powder. The combustion blows off tail cup, ignites incendiary filling and ejects it for a maxi-mum of 75 yards. |
REMARKS: |
The bomb and the delay are calculated to permit penetration inside of a struc-ture before detonation. The incendiary oil filling is of a very sticky composition and will normally adhere to any objects, including vertical walls. |
The M69X incorporates a 4.5 ounces charge of tetryl to produce an anti-person-nel effect. Overall dimensions of the M69X duplicate those of the AN-M69, but the amount of incendiary mix is reduced (.4 lb less). Operation of the M1 fuze ignites a safety fuze lead terminating in the M106 detonator, which explodes the tetryl frag-menting 65% of the bomb case after ejection of the incendiary material, following a pre-determined time delay of 5. to .6 minutes (30% - 1/2 min.; 30% - 2 min.; 20% - 4 min.; 20% 6 min.). The time delay is varied by adjusting the length of the safe-ty fuze. |
