Q

What does “enhanced blast” for HE bombs mean?

A

Adding metal powder to HE explosive increases the blast effect. The use of Aluminium is common ie Tritonal but other metals and chemicals are increasing the power of explosives and volumetric blasts.

  • -SAM (surface to Air)
  • -SSM (Surface to Surface)
23
Q

What does the SAD on missiles do?

A

Link between the fuze and warhead
Provides safety break before weapon launch
Arms the weapon after launch
A self destruct device (SD)

24
Q

What are the two types of missile propulsion and their subcategories?

A

Airbreating

  • Ramjet
  • Turbo-jet

Propellant

  • Solid
  • Liquid
25
Q

What type of missiles have a Self Destruct fusing and describe the methods of activation?

A

-AAM -SAM

  • Loss of command
  • Time Delay
  • Power run down
26
Q

What are Rollerons on guided missiles and what missiles are they fitted to?

A

Small notched wheels on the tips of the rear tail fins to provide stability in flight. These are fitted to short range AAMs.

27
Q

What are the 3 sea mine positions?

A
  • -Moored
  • -Drifting
  • -Bottom
28
Q

What are the 5 sections of a torpedo?

  • -Afterbody (Contains turbines etc)
  • -Tail (Steering rudders)
29
Q

What are the two aircraft store categories and examples?

A
  • -Expendable (bombs, missiles, rockets)
  • -Non-expandable (fuel tanks, missile racks, targeting pods)
30
Q

What types of maritime ordnance can be encountered?

A

Sea Mines, torpedoes, depth charges, ahead throw weapons, limpet mines

31
Q

What methods can a sea mine Influence fuse use to function the mine when a ship is within range?

A
  • Seismic
  • acoustic
  • underwater electric potential (UEP)
  • a combination of these.
32
Q

How do underwater mines and depth charges destroy their target?

A

The blast affect of the detonation travels through the water breaking the target vessel.

33
Q

What are the main components/sections of a torpedo?

A

Guidance - Acoustic homing only
Warhead - Main charge, booster, detonator and fuze
Energy - Fuel (many types), compressed air, batteries
After body - Turbines, engines, motors, propellants, controls steering and depth
