Projected Munitions Flashcards
(36 cards)
How do you ID HE projectile?
- heavy metal one-piece construction
- most US HE projectiles have a welded base color
- most projectiles look like a large bullet
- color comes and markings apply
How do you ID HE mortars?
- have a nose fuse and not a tail fuse
- most fin stabilized mortars have a gas check band or O-band rather than a bourrelet, which traps propellant gas on the projectile on firing
- cartridge is contained in either an ignition cartridge holder, fin extension, or fin assembly provided with radial ignition holes for ignition of the propellant
What are the HE projectile fuses?
- point detonating
- base detonating
- variable time
- electronic time
- mechanical time
- powder train time fuse (PTTF)
What are the HE mortar fuses?
- point detonating
- variable time
- electronic time
- mechanical time
- powder train time fuse
What are the safeties of HE projectiles and mortars?
Projected->projectile->
HE, frag, move, + fuse safeties
Projected->projectile->
HE, frag, move, + fuse safeties
How do you ID ejection projectiles?
- bases are either pressed on or screwed on
- if base is screwed on you have spanner holes
- if base is pressed on you will have shear pins and twist pins
How do you ID ejection mortars?
- most ejection mortars will be illumination
- longer than average motors
- looks cylindrical
- look for shear pins near the base of the mortar where the tail boom meets the base of the munition
What are the ejection projectile fuses?
- variable time
- electrical time
- mechanical time
- powder train time fuse
What are the ejection mortar fuses?
- variable time
- electrical time
- mechanical time
- powder train time fuse
What are the safeties of ejection projectiles and mortars?
Projected->projectile/mortar-> base safeties-HE, frag, move, eject illumination-add fire C/S gas-add fire, chem WP or PWP-add WP, fire
How do you ID bursting smoke projectiles?
- use color codes to assist in ID
- usually one-piece construction
- US projectiles may have a milled or solid base plate
- may have a burster adapter
How do you ID bursting smoke mortars?
- look like HE mortars
- use color codes to assist in ID, may have a burster adapter
What are the safeties of bursting smoke projectiles/mortars?
Projected->projectile/mortar->
HE, frag, move WP, fire, add fuse safeties
How do you ID chemical projectiles/mortars?
- use color codes
- use ejection ID features and/or bursting smoke ID features in conjunction with color codes
- may have a filler plug of adapter
What are the chemical projectile fuses?
- point detonating
- base detonating
- variable time
- electronic time
- mechanical time
- powder train time fuse (PTTF)
What are the chemical mortar fuses?
- point detonating
- variable time
- electronic time
- mechanical time
- powder train time fuse (PTTF)
What are the safeties of chemical projectiles/mortars?
Projected->projectile/mortar->
HE, frag, move, chem
How do you ID HEAT projectiles?
- break of seam near the major diameter
- two dissimilar metals at the break in the major diameter
- will have some sort of stand off
- may have spanner holes at the break in the major diameter
- may have cap housing piezoelectric crystals
- can be spin or fin stabilized
What are the HEAT projectile fuses?
- point initiating base detonating
- base detonating
What are the HEAT projectile safeties?
Projected->projectile->
PIBD-HE, frag, move, EMR, static, PE/lucky, jet
BD-HE, frag, move, jet
How do you ID HERA/RAP projectiles?
- HE projectiles connected to a rocket motor
- normally two piece construction
- will only have one venturi (rocket nozzle)
- will have a rotating band
What are the HERA/RAP projectile fuses?
- point detonating
- variable time
- electric time
- mechanical time
What are the HERA/RAP projectile safeties?
Projected->projectile->
HE, frag, move, ejection
How do you ID HEP projectiles?
- has a blunt rounded nose
- has a short ogive
- will only incorporate a base detonating fuse
