Description: The mechanism for this fuze is very similar to that described for the Nose Time Fuze Mk 18. In the Mk 22, however, the centrifugal weights do not have "kick-off" springs, and the Mk 22 is slot-set instead of lug-set, as the Mk 18. Also, the Mk 22 is very similar to the Army M43A3. |
Mods 4, 5, and 6 are identical, but are made by different manufactures. |
