fc a school weapons – ammunition
Exam-Graded A
Ammunition - Correct Answers-Any destructive projectile that can effectively damage or
destroy a selected target
Can be put in the path of the enemy to change their course - Correct Answers-
Ammunition
To use ammunition to its greatest effect a sailor must understand - Correct Answers-
ballistics,propellants,fuzes,ammunition safety precautions
Ballistics - Correct Answers-The science of how ammunition moves inside the gun and
leaves the muzzle
When the ammo moves inside the gun... - Correct Answers-Interior ballistics
When the ammo moves outside the gun... - Correct Answers-exterior ballistics
A mixture of explosives is called - Correct Answers-Propelling charge
When fired shoots the projectile from the barrel to the target - Correct Answers-
propelling charge
The main parts of ammunition - Correct Answers-primer,brass cartridge case,
propellant, and projectile
The process for firing the projectile from the ammunition - Correct Answers-1.the firing
pin strikes the primer
2.the primer ignites the propellant charge
3.the propellant charge fires the projectile
Reduced propelling charge - Correct Answers-contain less than the service load, or
standard amount of powder,used for target practice.
saluting propelling charge - Correct Answers-Used when firing a gun to render honors,
consists of only a cartridge case containing black powder load and primer
cleaning propelling charge - Correct Answers-Used when a round of ammunition is
jammed in the gun chamber,fired by extracting the full sized case and leaving a smaller
clearing charge
, service charge - Correct Answers-used in actual firing of the weapon during combat,
qualifications of training...full charges designed to propel the projectile from the
weapon!!!
inertia - Correct Answers-the way an object resists speeding up or slowing down
forces of inertia - Correct Answers-Setback,angular acceleration, centrifugal force,
creep, impact
setback - Correct Answers-refers to how the inertial force causes the bullet to resist
moving forward out of the gun barrel
angular acceleration - Correct Answers-how inertial force causes the bullet to resist
rotating as it passed through the gun barrel
centrifugal force - Correct Answers-the inertial force created by the bullet passing
through the rifled bore causing the bullet to rotate
This force of inertia causes improved accuracy - Correct Answers-centrifugal force
Creep - Correct Answers-refers to how fuze move forward inside the projectile as the
projectile flies through the air
impact - Correct Answers-the bullet coming to a stop when it strikes the target
What does the fuze mechanism inside the propelling charge set off? - Correct Answers-
explosion of gases
What does the forces of inertial forces help improve - Correct Answers-accuracy,
impact, and penetration
Fuze - Correct Answers-component that sets of the projectiles bursting charge
Mechanical time fuze - Correct Answers-set to activated following a specific amount of
time after the projectile is fired
Percussion fuze - Correct Answers-activate by: the projectile striking the target or after
the projectile penetrates the target
fuze activated by impact - Correct Answers-percussion fuze
Combination fuze - Correct Answers-activates by either time or impact
variable time fuzes - Correct Answers-activate when the projectile gets near the target
