| 2. Description |
|
General. Fuze Mk 52 Mod 2 (Auxiliary Detonating) is identical with Fuze Mk 44 Mod 2 (Auxiliary Detonating) with the one exception that the detent springs in Fuze Mk 52 are weaker to allow the fuze to arm at a lower rotational velocity. Fuze Mk 52 arms at a ro-tational velocity within the range of 1600 to 1900 rpm which represents approximately 30 feet of travel in the round in which it is used. |
|
Use. Fuze Mk 52 Mod 2 is used in the 5.0-inch High Capacity Spin Stabilized Surface Rocket (Complete Round) Mk 16 Mod 0 (see OP 1415). |
