(502d) When a munition is armed _________?
A.
It is ready to be uploaded to the airframe
B.
All personnel should be at least 4000 feet away
C.
The next normal event initiates functioning of the fuse
D.
It is ready to be dropped from the aircraft
Correct Answer
C. The next normal event initiates functioning of the fuse
Explanation When a munition is armed, the next normal event initiates functioning of the fuse. This means that once the munition is armed, it is not immediately ready to be uploaded to the airframe or dropped from the aircraft. Instead, it requires a specific event, which could be a trigger or a specific condition, to initiate the functioning of the fuse. This ensures that the munition will only explode or function as intended when the desired event occurs, preventing accidental detonation or premature activation.

A. Filling identification and corrosion control
Explanation Projectiles are color coded for two main reasons: filling identification and corrosion control. The color coding helps in easily identifying the type of filling inside the projectile, such as explosive, smoke, or illuminating material. This is crucial for proper handling, storage, and use of projectiles. Additionally, color coding is used for corrosion control, as certain colors are associated with specific types of protective coatings that help prevent corrosion and ensure the longevity of the projectiles. By color coding projectiles, it also helps to prevent 2W1s (personnel responsible for loading ammunition) from loading incorrect rounds, which could have serious consequences.

(503b) What acts a gas seal and stabilizes projectile in flight by gripping the rifling grooves in barrel, causing the projectile to spin?
A.
Rotating band
B.
Fuse
C.
Propellant
D.
O ring
Correct Answer
A. Rotating band
Explanation The rotating band acts as a gas seal and stabilizes the projectile in flight by gripping the rifling grooves in the barrel, causing the projectile to spin. This spinning motion improves accuracy and stability by creating gyroscopic stability, which helps the projectile maintain its trajectory. The rotating band also helps to create a gas seal between the projectile and the barrel, preventing gas leakage and maximizing the propulsion force generated by the propellant.
