in the RIPPLE fire position, the intervalometer converts
the firing pulse into a ripple pulse and successively fires
all rockets at 95-millisecond intervals. Ripple firing
operates the same on all pods.
The intervalometer used with the 2.75-inch pod has
a shaft that extends through the aft bulkhead of the
launcher and a knurled knob with a reference (index)
mark mounted on the shaft. Intervalometer switch
positions are marked on the aft bulkhead of the center
The intervalometer should NOT be
manually rotated through the numbered positions
except when checking an empty pod.
Intervalometers used in the LAU-10 (series) pods
cannot be manually rotated. When the intervalometer
has made a complete four-round firing cycle, it
automatically homes in on the original starting point
(zero) and does not recycle without first de-energizing
the circuit, and then re-energizing it.
5.0-INCH (SERIES) LAUNCHERS
The LAU-10 (series) launchers are reusable
launchers intended for shipping (without warheads),
stowing, and firing four 5.0-inch rockets. When loaded
with four completely assembled rounds, the total
weight varies with rocket configuration from 500 to
The rockets are retained in the launcher tubes
during shipping, handling, and flight by engagement of
a spring-loaded detent pawl in the rocket detent groove
