Description
This is an arming vane type of fuze with mechanical delay. Upon arming, detents (spring actuated pins) fly out so as to allow the bellows to operate. It is a tail fuze and when armed it functions on water pressure. Depth setting is made by a dial located on the exterior of the fuze body which operates a long spindle in the interior of the bomb fuze. This varies the compression on the depth spring. By turning the dial, one of five settings can be obtained, namely: 25, 50, 75, 125, and 175 foot depths.
In operation, it is somewhat similar to the AN-Mk 224 except that water pressure forces the initiating explosive into a stationary firing pin with only one system of bellows. The AN-Mk 230 used on the new GP bombs resembles this fuze; however, it is smaller in diameter and has different threads to fit the GP bombs.
Only the AN-Mk 229 Mod 1 Fuzes have been issued for service use.
