ARMY PROJECTILE FUZES |
Type 4 - Super Detonating Fuze |
Use: Ho-5 20-mm H.E.I. projectiles. |
Description: |
Over-all length with gaine: 59/64 inch. |
Threaded length: 1/4 inch. |
Number of threads: 6. |
Construction: This is an air-column fuze with the gaine enclosed in the fuze body. The fuze is of two-piece construction, with the upper part containing the air column and pri-mer and the lower part containing the gaine. The inclusion of the gaine in the fuze body leaves space for more explosive in the projectile. |
Operation: There are no arming features in this fuze. On impact, the closing disk is crushed inward, compressing the air in the column and firing the gaine. |
