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 to date. 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 bomb’s 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 directives. Adapter Boosters Install adapter boosters by using the procedures discussed in the following text. WARNING Fuzing for the thermally protected GP/TP bomb to obtain cook-off protection is limited to Fuze M904E4 with thermally protected adapter-booster M148E1, electric fuzes 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.

If you use a mechanical tail fuze, install the M150/T46 adapter booster with the booster cup. 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 diameter fuzes. 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 closing plug. 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 Tai1 Fuzes The Mk 376/FMU-139 series electric and elec- tronic tail fuzes are currently being used in the Navy.
