| Description |
|
These fuzes are very similar to the Type C and Type N fuzes. The only difference in the Y and Y-1 is that the Y-1 has 3.5 in. longer arming spindle and tube. The vanes are se-cured to the arming spindle by a locking pin. Two screws secure the brass collar to the top of the arming tube. The striker and detonator holder both have two projections which move in the keyway and thus keep the firing pins in line with detonator. A safety pin fits through the brass and the arming spindle to prevent the vanes from rotating. Two steel balls in the striker rest against a recess in the fuze body and are prevented from moving inwards by the arming spindle. |
| Operation |
|
The safety pin is withdraw when the bomb falls; the vanes rotate and with-draw the arming spindle from the striker. The steel balls move inwards to free the striker, which now is held by a creep spring. On impact, the firing pins hit the detonators. |
