| Description: |
|---|
| The M46 grenade is a ground burst munition consisting essentially of a 1,5 inch diameter cylindrical shell body loaded with approxi. mately 30 grams of Comp A5 in a shaped charge. A nylon ribbon loop stabilizer is provided to orient and arm the grenade, The inertia type fuze has a slide assembly containin g a M55 detonator and a coil spring to force the slide into the armed position. The M46 grenade has a smooth inner side wall that makes the body wall stronger than the embossed wall of the M42 grenade. The wall does not have optimum fragmentation characteristics of the M42 grenade wall, but has extra strength to prevent compression failure during setback. |
| Use: |
|---|
| To provide antimateriel and antipersonnel] capabilities in submissiles carried in the last three aft layers in the 155MM M483 projectile for howitzers. |
| Functioning: |
|---|
| Upon expulsion from the projectile, the nylon ribbon stabilizer extends and orients the grenade, and due to rotational forces, unthreads the threaded tiring pin from the weight (semi-armed), and pulls the tiring pin out of the slide assembly. The slide assembly is then free to move, and moves into the armed position by action of the slide spring and centrifugal force. The spring maintains the slide assembly in the fully armed position. Upon impact, the inertia weight drives the firing pin into the M55 detonator, initiating the firing train. A shaped-charge jet is expelled downward while the body bursts into a large number of small fragments, The jet is capable of penetrating approximately 2,75 inches of homogeneous armor plate. Antipersonnel effects are obtained by fragmentation of the grenade body, |
