Inspecting Rocket Components
As the rocket components are removed from their
shipping containers, inspect them by performing the
steps listed below. Dispose of defective items according
to current directives. The components you inspect
include launchers, warheads, fuzes, and rocket motors,
to include their fins.
To avoid personal injury and equipment
damage in an operation involving assembly,
disassembly, fuzing, defuzing, or cleaning,
you must do the work in a designated area.
This area must be safely located away from
other explosives and vital installations. Only
the smallest number of rockets practicable
personnel essential to the work should be
permitted in the vicinity. Refer to the
NAVORD OP 3565 for RADHAZ pro-
cedures and precautions.
WARHEADS.Inspect the warheads as
Warheads that are cracked or have a gap
between the fuze adapter and the warhead
Verify that the warhead is not cracked and no
gap exists between the fuze adapter and the
On the Mk 32 warhead, verify that the fuze is
Verify that the base and fuze cavity threads are
not damaged or corroded.
Do not use a warhead that does not have the
base fuze hole closed by a steel plug or a base
fuze. Base fuzes must not protrude more
than 1/16 inch. Detonation could occur
during handling or firing.
NOTE: Do not disassemble base adapters from
the warheads to check for base plugs.
Verify that the warhead contains a base fuze or
a steel base plug. When installed, ensure the
base fuze does not protrude more than 1/16
FUZES.Inspect the fuze as follows:
Fuzes that are damaged are hazardous.
Detonation may occur.
Do not use Mk 93 or M414 fuzes with nose
cones that are completely penetrated by
scratches, cracks, or abrasions. Minor
scratches or abrasions do not affect their
performance or safety.
Verify that the fuze body is not damaged.
ROCKET MOTORS.Inspect the motor as
Verify that the motor tube is not dented, deeply
scratched, gouged, or corroded.
Use an authorized metal shielding band
assembly only. Do not substitute the Mk 71
motor plastic fin retainer band because it
offers no RADHAZ protection.
NOTE: Rocket motors packaged in individual
wooden containers may be received with the
1516140) installed. This band is obsolete and
must be replaced with shielding band assembly
RADHAZ barrier are in place.
Verify that the nozzle plug is in place.
For rocket motor Mk 71, verify that the fin
retainer is in place, the fins are not bent or
broken, and the fin pin is clean and free of
foreign matter. The spring-loaded fins must be
exercised four to six times.
