What is a bomb body?
The main casing of a bomb; the starting point for building a complete bomb.
It serves as the structural framework for all other components.
What is a Fuze Well?
A threaded opening in the bomb that allows for the installation of a fuze and/or booster.
This component is critical for the bomb’s detonation mechanism.
What is a Charging Well?
A cavity that holds an electrical fuze initiator (e.g., FZU-48) for electrical fuzes.
It is essential for the activation of the bomb’s fuze.
What are Conduits?
Metal tubes inside the bomb body that connect the fuze well(s) to the charging well.
They facilitate the transfer of electrical signals.
What are Suspension Lugs?
Strong metal loops used to attach the bomb to an aircraft’s bomb rack. Ammo troops also use them to lift the bomb.
They are crucial for the safe transport and deployment of bombs.
What are Closure Plugs?
Plastic plugs that protect the fuze well threads from damage and debris.
They help maintain the integrity of the fuze installation.
What is the Zinc Anticorrosion Spacer (Zinc Ring)?
A ring placed in the fuze well to prevent galvanic corrosion between the steel bomb and the aluminum fuze threads.
This component enhances the longevity of the bomb’s functionality.
What are the three possible types of bomb fillers?
- Explosive (live)
- Inert (concrete/simulant)
- Empty (no filler)
These fillers determine the bomb’s intended use and effectiveness.
What type of targets are GP bombs designed for?
Soft, fragment-sensitive targets (troops, fuel dumps, radar sites, parked aircraft).
General Purpose bombs are versatile and used in various combat scenarios.
What is the Net Explosive Weight (NEW) of an MK-82/BLU-111?
192 lbs.
This weight indicates the amount of explosive material contained in the bomb.
What is the NEW of an MK-83/BLU-110?
445 lbs.
This bomb is larger and designed for more significant explosive impact.
How is the BLU-126 (Low-Collateral Damage) bomb identified?
By three yellow bands on the front and one yellow band on the back.
This identification helps differentiate it from standard bombs.
What is the key difference between the BLU-126 and a standard MK-82?
It has much less NEW (27 lbs vs. 192 lbs) to reduce collateral damage.
This design is intended for precision strikes.
What is the NEW of an MK-84?
945 lbs.
This is one of the largest general-purpose bombs.
What is the NEW of a BLU-117?
930 lbs.
This bomb is designed for high-impact scenarios.
What is unique about the BLU-129 (Precision Lethality) bomb case?
It is made of mostly composite material (not just steel).
This construction enhances its performance and reduces collateral damage.
How is the BLU-129 identified?
By yellow diamonds painted around the nose of the bomb.
This visual cue is crucial for identification in the field.
What is the key external feature of ALL penetrator bombs?
They have ONLY a tail fuze well (no nose fuze well).
This design is specific to their intended use against hardened targets.
What type of fuzing are penetrators designed for?
Delayed fuzing (to allow time for penetration before detonation).
This is critical for their effectiveness against fortified structures.
What are penetrators specifically designed to attack?
Hardened targets (bunkers, reinforced concrete structures).
Their design allows them to breach tough defenses.
What is the BLU-109?
A 2,000-lb class penetrator warhead.
It is one of the most commonly used penetrator bombs.
What is its NEW?
535 lbs.
This weight indicates the amount of explosive material contained in the warhead.
What is the BLU-118?
A 2,000-lb class Thermobaric weapon.
It is designed for maximum blast effects in confined spaces.
What bomb case does the BLU-118 use, and what is its purpose?
It uses the BLU-109 case with a different explosive filler; designed for sustained blast pressure in confined spaces like tunnels and bunkers.
This design maximizes its effectiveness against fortified positions.
