BREAKOUT. Breakout is the term used to
define the physical removal of ammunition from the
magazine. Weapons are broken out, by direction of
the ordnance handling officer (OHO), in accordance
with the load plan.
When ordnance breakout is
directed by the OHO, the breakout crew records the
type, lot number, and quantity of ordnance broken out.
Then, the crew passes this information back to ordnance
control so that an accurate account and location of
weapons and related material on board can be kept up
UNPACKING. You must depalletize the bomb
body and place it on the appropriate bomb skid or
assembly stand. Prior to depalletizing, ensure that
gloves, steel toe shoes, and face shields are worn. When
depalletizing a bomb body, you need to remove the
banding straps and the top section of the metal pallet,
the shipping cap on the rear of the bomb body, and all
plastic shipping plugs from the fuze cavities. Then,
install hoisting bars, as necessary, for manual handling
of the bombs. Other suitable hoisting equipment may
be used when available. Finally, place the bomb on the
appropriate bomb skid or assembly stand.
INSPECTION. You need to inspect the bomb for
damage, stripped threads, cracks, or broken welds.
Make sure the bottoms of the suspension lug eyes are
flush with the weapon surface. Check to see that the
bombs V-groove is clean and undamaged. Check the
fuze wells to ensure they are clean and dry. If
nose elements and/or electric tail fuzes are to be used,
check the electrical connectors to ensure they are not
bent or corroded. Press gently with a wooden dowel on
the connectors to ensure that they are firmly seated.
Inspect thermally protected bombs for loose or chipped
coating. Bombs that are missing more than 15 square
inches of thermal coating in one spot are not considered
thermally protected and are restricted from issue to
aircraft carriers. Damaged or otherwise unserviceable
bombs should be disposed of by following current
Install adapter boosters by using the procedures

Fuzing for the thermally protected GP/TP
bomb to obtain cook-off protection is limited
to Fuze M904E4 with thermally protected

FMU-139, Mk 376, and Mk 346 with thermal
shield. Any other fuzing greatly increases the
probability of early detonation of a bomb
engulfed in a fire.

BOOSTERS. Remove the adapter booster from the
shipping container. If a mechanical nose fuzing is used,
install an M148 adapter booster. If you use a mechanical
tail fuze, install the M150/T46 adapter booster with the
NOTE: In addition to the booster cup, the
M150 and T46 adapter booster consists of
two separate explosive components. The
primary adapter booster contains a 2.0-inch
diameter tail fuze. The T46 (series) contains a
fuze adapter sleeve for use with 1.5-inch
MECHANICAL NOSE FUZING. When you
use mechanical nose fuzing, an M148 adapter booster is
installed as follows:
1. Unpack the adapter booster and remove the
2. Inspect the adapter booster internally and
externally to ensure all parts, including threads, are
clean and undamaged
3. Inspect the bomb nose fuze cavity.
4. Loosen the setscrew in the bomb body.
5. Screw the adapter booster into the bomb, and
tighten it with a spanner wrench until it is firmly seated
6. Tighten the setscrew in the bomb body against
the adapter-booster threads.
Installation of Electric and Electronic
The Mk 376/FMU-139 series electric and elec-
tronic tail fuzes are currently being used in the
Navy. The following are general procedures you should
