Description
Military Operations on Urbanized Terrain (MOUT) Fuze, PD, Mk 399 Mod 1 is used with high explosive (fragmentation) 105mm cartridges and 155mm and 8 inch projectiles.
The MOUT fuze can be set to function superquick (PD) or Delay. In the Delay mode, the fuze is designed to penetrate urban structures, i.e., buildings and bunkers, then function the projectile inside. In the PD, the fuze functions as a standard PD fuze. This setting will maximize destruction of the walls of an urban structure and is also useful for ranging in on targets. The fuze is shipped SET DELAY which is the primary MOUT mode.
The fuze has an aluminum PD head assembly threaded onto a hardened steel body. Internally, the fuze is composed of a PD head assembly, selector switch assembly (screwdriver or M18 fuze wrench operated), pyrotechnic delay assembly, the Mk 49 Mod 2 safe & arming device which provides 400 calibers safe separation distance, and a booster pellet.
