After removing fuzes from
their containers, save the
inner and outer packing mate-
rial and desiccant. Put it all
back in the original container
so that it’ll be available for
repackaging turn-ins.
The styrofoam inner pack-
ing material will absorb mois-
ture from humid air. That can
make it difficult to remove the
fuzes, so keep the container
closed as much as possible.
Before firing fuzed ammu-
nition, make sure the fuze is
fully seated. The fuze shoul-
der must be seated smack on
the projectile’s nose with no
threads or space showing.
Save all liner and outer
fuze packing material
for repacking turn-ins

Fuzes
The HELLFIRE’s environmental protection cover
(EPC) kit may be installed on the nose of the missile
in cold weather to protect the seeker dome prior to
launch. There are two configurations of the EPC:
The MH51, NSN 1377-01-159-3918, can be used
on the AGM-114A/B/C/K HELLFIRE missile.
The MT26, NSN 1377-01-359-2923, has a longer
cable for use on the AGM-114F HELLFIRE missile.
Be sure the missile dome is ice-free before you
install the EPC. It’s a tight fit and may shatter if you
try to install it on an icy missile dome.
Check missile dome for
ice before installing EPC
Fuzes are
extremely
shock sensitive.
Handle and transport
these items with
extreme caution.
Mishandled fuzes could
detonate or cause the
round to malfunction.
Make sure the safety pins, pull wires or any other safety device on fuzes are in
place and in good shape. Never remove the safety device until you’re ready to fire.
If the safety device is missing, broken, corroded or dented, turn in the fuze or
report it.
Know which fuze tools are authorized for which fuzes. Then use the tools gently
when you screw on a fuze. Never force, spin, roll or drop a fuze.
When a round is
issued to you already fuzed, leave it fuzed unless your ammunition pubs give you a
different fuze for the round.
Unauthorized or altered fuzes are also off-limits. Ammunition with no fuze or the
wrong fuze can blow up in the bore or become a dud downrange.
Before fuzing, make sure the fuze cavity is clean. Use a lint-free, clean cloth and
wooden (not metal) stick to clean the cavity. For the fuze to seat right, the fuze and
projectile threads must be clean. Never use a fuze or projectile with damaged
threads. Turn it in.
Keep fuzed ammunition out of the path of your weapon’s recoil or anything else
that might bang it. If a round is hit, isolate it with a tag explaining what hit the
round, then report it immediately. Do the same for any damaged rounds, fuzed
or not.
Prepared fuzes that haven’t been fired
need special handling. Clean them well
before repacking in the original packing.
For separate-loading ammunition,
remove the fuze, pack it carefully and
replace the projectile’s plug and gasket.
Write on the box the date the ammunition
was repacked. Use that ammunition first
next time you fire to cut down on opened
boxes.
Removed fuzes should be reset to their
initial setting before being repacked.
M732 proximity fuzes (DODIC N464) must be stored nose down (arrow on box
pointing up) to prevent the battery electrolyte from leaking.
