Q

How do you ID HE mortars?

A
  • 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

  • variable time
  • electric time
  • mechanical time
23
Q

What are the HERA/RAP projectile safeties?

24
Q

How do you ID HEP projectiles?

A
  • has a blunt rounded nose
  • has a short ogive
  • will only incorporate a base detonating fuse
25
Q

What are the HEP projectile fuses?

A

-base detonating

26
Q

What are the HEP projectile safeties?

A

Projected->projectile->

BD-HE, frag, move

27
Q

What does AP/APDS/APFSDS/APCSDS stand for?

A

AP-armor piercing
APDS-armor piercing discarding sabot
APFSDS-armor piercing fin stabilized discarding sabot
APCSDS-armor piercing cone stabilized discarding sabot

28
Q

How do you ID AP projectile?

A
  • may have a hole in the base the size of a quarter or smaller for tracer element
  • most have short blunt ogive for purposes of penetration
  • may have an ogival or conical windshield for improved ballistic secured to the nose of the projectile
  • normally solid one piece construction
29
Q

How do you ID APDS projectile?

A
  • consist of sub caliber AP core of high density material within a full caliber carrier or sabot
  • the core alone proceeds to the target
  • may have a hole in the base the size of a quarter or smaller for tracer elements
  • the sabot imparts velocity and spin to the AP core on firing, and then falls away after leaving the weapon bore
30
Q

How do you ID APFSDS/APCSDS projectiles?

A
  • some AP projectiles are the hypervelocity armor piercing type.
  • consist of sub caliber AP core of high density material within a full-caliber carrier or sabot which is fin or cone stabilized
  • sabot falls away after leaving the weapon core
  • core alone proceeds to target
  • may have a hole in the base the size of a quarter or smaller for tracer elements
31
Q

What are the fusing for AP/APDS/APFSDS/APCSDS projectiles?

A

None

32
Q

What are the AP/APDS/APFSDS/APCSDS projectile safeties?

33
Q

What does APHE stand for?

A

armor piercing high explosive

34
Q

How do you ID an APHE projectile?

A
  • normally solid one-piece construction
  • may contain a windshield for improved ballistics
  • normally have hammer rings on the ogive
  • may contain tracer element
  • if hole in the base of the round is the size of a half dollar or larger this is a provision for BD fusing
35
Q

What are the fuses for APHE projectile?

A

-base detonating

36
Q

What are the APHE projectile safeties?

A

Projected->projectile->
