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.
