24
Q

One of you gunners attempts to fit an M577 Fuze onto an HE projectile. Explain why this cannot be done?

A

It is an igniferous Fuze used on carrier projectiles. It doesn’t have a booster and would be a dud.

25
Q

What is the type of primer used with the M777?

A

M82

26
Q

What is the purpose of the booster on a disruptive Fuze?

A

A necessary unit with an HE projectile, it amplifies the shock wave enough to detonate the HE bursting charge.

27
Q

What are the types of granulation for the following propelling charges

A

(Green bag) M3 - single perforated
(White bag) M4 - multi perforated
(Mac Low) M231 - single perforated
(Mac High) M232A1 - triple perforated
(Red Bag) M119A2 - multi perforated

28
Q

What are the types of fuzes and what actions do they produce?

A

Igniferous - produces a spark or spit of flame to ignite the expelling charge in a carrier projectile.

Disruptive - produces a detonation to detonate a bursting charge of an HE or WP projectile

29
Q

What are the reasons for painting ammunition?

A

Prevent rust
Ease of identification
Camouflage

30
Q

What are the current 155mm projectiles in service today?

A
  1. HE M107 and M795
  2. Smoke DM45
  3. Illumination M485
  4. RAP M549
  5. Excalibur M982
31
Q

List the components of a propelling charge?

A

Primer
Igniter
Propellant

32
Q

With the C32 Fuze, what is the difference in functioning between a Fuze that is set to proximity MANUALLY and INDUCTIVELY?

A

MANUALLY - when the Fuze reaches 7sec of flight, the proximity sensor starts target detection.

INDUCTIVELY - 2 seconds before the programmed Fuze setting is reached, the proximity sensor starts target detection.

33
Q

What is the standard weight square zone for 155mm HE?

A

4 squares

34
Q

What is the definition of an artillery Fuze?

A

It is a device used with a projectile to cause it to function at the time and circumstances required.

35
Q

Label the exterior parts of the HE projectiles?

A
  1. Ogive
  2. Shoulder
  3. Bourelet
  4. Body
  5. Driving band
  6. Base
  7. Base plate
36
Q

Name the methods used to mark ammunition?

Stencilling
Stamping
Label and tags
Colour coding
