| Description |
|
Type O fuze is the same in construction as Type A fuze. Actually, Type O is a combina-tion of the fuze arming mechanism and the fuze A, accomplished by removing vanes of the A and screwing in place the arming sleeve. Length of the extension rod may vary to suit the varying lengths of the tail. |
| Operation |
|
The vanes on the extension arm rotate and withdraw the spindle into the hollow sleeve of the arm. After the spindle is withdrawn, the operation is the same as the Type A, ex-cept that on impact the inertia striker covercomes the creep spring and contacts the detonator, setting the explosive train in motion. |
