Gun Ammunition
Projectile terms
Fuze or Fuse
Projectile Class
Special Projectile
100
The propelling charge provides thrust to eject this part of the Ammunition
What is Projectile
100
Shell fragments
What is Shrapnel
100
A tube or cord with combustible matter for igniting an explosive; an ignition device incorporating mechanical and/or electronic components
What is Fuze or FUSE
100
three general classes of projectiles
What is Penetrating, Fragmenting, and Special Purpose
100
are not intended to inflict damage by blast or fragmentation
What are Special Purpose Projectiles
200
This container holds the ignition system and the propellant.
What is Propelling Charge
200
Strips of metal foil dispersed from projectiles to confuse enemy radar by creating false blips
What is Chaff
200
A design for detonating a charge, as in a projectile, within a predesignated radius of a target; called VT, for variable time, to keep its development a secret in World War II
What is Proximity fuze
200
Include shells that can penetrate the armor of a ship before exploding
What are Penetrating projectiles
200
A bright flare illuminates an enemy target or terrain as it slowly descends by parachute
What is an Illum Projectile
300
This part includes the detonating fuze, the booster, and the burster charge.
What is Payload or Projectile
300
Commonly called “star shells,” these projectiles are usually filled with magnesium and are used at night to light up (illuminate) the target.
What is Illuminating Projectile
300
Delays projectile arming for a set time after it is fired
What is Controlled variable time fuze (CVT)
300
designed to damage by blast effect and fragmentation, breaking up into high-velocity shrapnel
What is Fragmenting Projectile
300
The foil strips from this projectile scatter into the air, causing interference with enemy radar signals.
What is chaff projectile
400
This type of ammunition is packed behind the projectile, either in bags or metal cartridge cases.
What is Bag Ammunition
400
A heavy antiaircraft barrage through which aircraft must fly to attack their target
What is flak
400
contains a clock mechanism that explodes the projectile after a preset amount of time elapses.
What is Mechanical Time Fuse
400
Must be insensitive to the shock of impact, to permit penetration and subsequent detonation
What is Penetrating Projectile
400
Projectiles contain sand or other inert material to simulate the weight and balance of burster charges; they are used for surface gunnery practice.
What are target projectiles
500
This type of ammunition is one piece and is used in 3" or smaller guns.
What is fixed ammunition
500
A projectile designed to break into many small, high-velocity shrapnel fragments when detonated
What is Fragmenting Projectile
500
Commonly used in fragmenting shells.
What is Proximity Fuze (VT Fuze)
500
Used against lightly armored surface targets such as torpedo boats, shore installations, or personnel.
What is HE-PD or Fragmenting Projectile
500
Once released, the fragments of white phosphorus projectiles are almost impossible to extinguish.
What are Incendiary projectiles
