ACCELERATION-DECELERATION FUZES

ACCELERATION-DECELERATION FUZES.— Acceleration-deceleration fuzes are similar to impact and time fuzes because they require acceleration for a given time to complete the arming cycle. After the arming cycle is completed and the rocket velocity begins to drop, deceleration causes the fuze to function. The Model 113A is the only acceleration- deceleration fuze in use by the Navy at this time. It is a base-mounted fuze that is permanently installed in the WDU-4A/A flechette warhead. 2-11 WRENCH SLOTS (2) FUZE, MK 362 MOD 2 ROCKET, FMU-90/B 5.25 in> FUZE, BASE DETONATING, MK 191 MOD 1 NOSE CAP WRENCH FLAT (2) BOOSTER CUP FUZE, MK 188 MOD 0 AOf0212 Figure 2-12.—Impact firing fuzes.
