Q

State the primary purpose of reticles in ir air to air missiles

A

Modulates ir energy via opaque and clear tracking windows and varies output of the electrical signal sent to the gcs based on where the energy hits the reticle

15
Q

List each nuc effect and provide example of each to structure and people

A

Blast - people collapsed lungs, structure collapse
Thermal - people flash blinded, structure on fire
Radiation - people sickness and death

16
Q

How is nuclear detonation achieved in fission

A

Gun assembly/ implosion brings u235 or pu239 to supercriticality
Neutrons are injected into supercritical material
Fission chain reaction occurs
Bomb case ruptures, nuclear detonation

17
Q

How does a fusion weapon produce detonation with example

A

Primary fission creates heat/pressure
Heat/pressure compresses fusion secondary causing deuterium/tritium to fuse
Deuterium/tritium fusion releases neutrons causing subsequent fission

Example: all current warheads, b61

18
Q

List nuclear burst profiles

A

Air burst - enhances thermal / blast
Ground burst - enhances radiation
Subsurface burst - enhances ground shock

19
Q 
Match the following to description
B61
B83
W80-1
W78
A

B61 - gravity bomb employed by fighters and strategic bombers
B83 - gravity bomb employed by strategic bombers
W80-1 - air launched cruise missile
W78 - warhead employed by minute man 3

20
Q

Describe LGB concept of operation

A

Released ballistically, operator lases target, munition guides to laser spot. Meeker and designator must maintain Los with target throughout weapons tof.

21
Q

Advantages of LGB (list 3)

A 
Standoff from AAA
Simple to use
Man in the loop to impact
Accurate weapon with real time hit assessment
Can hit moving targets
22
Q

Disadvantages of LGB (list 3)

A 
Shorter standoff range to boosted weapons
Requires close in designator support
Los for weapon and designator required
Weather must support guidance
Battlefield obscurants
23
Q

Concept of operation for gps aided munitions

A

One released ins/gps guides to tgt regardless of weather
Guidance accomplished via tight gps/ins coupling
Gcu provides accurate guidance in gps/ins or ins only modes

24
Q

Advantages of gps munitions (list 3)

A

Standoff from Aaa and short range Sam
Adverse weather/ battlefield obscurant capable
Multiple delivery platforms
Multiple weapons and aim points per pass

25
Q

Disadvantages of gps

A

No man in the loop after release
Gps jamming impedes guidance
Cannot hit moving targets

26
Q

Factors determining delivery accuracy of gps bombs

A

Navigation error - (gps ins error) uncertainty of known target location relative to weapon
Guidance and control error - (weapon responsiveness) ability of guidance / control to steer to tgt
target location error - accuracy of target coordinates

27
Q

**Advantages of gp bombs

A

Plentiful
Good explosive weight
Good blast/frag
Building block for guided weapons

28
Q

**Define aspect angle

A

From tgt to attacker, starts at targets tail, attacker heading irrelevant

29
Q

**Define hca

A

Heading crossing angle…angular difference between target and attacker noses

30
Q

**Define Los

A

Line of sight…attackers nose to target

31
Q

**Disadvantages of semiactive guidance

A

Requires reference Doppler sent to missile before launch
Must maintain lock onto target Doppler
Seeker lock on before launch limits max range
Shooter must maintain target lock through tof

32
Q

**agm 65 concept of operations

A

Ir/eo sensor slewed to tgt
Tgt id’d and missile visually locked
Pilot fires missile
Missile guides to tgt

33
Q

**Tactical missile advantages

A

Precision
Standoff from small arms
Simple to use
Moving tgts

34
Q

**tactical missile disadvantages

A

Weather
Battlefield obscurants
Small warheads
