Match the following with description
Cbu 87
Cbu 89
Cbu 97
Cbu 87 - most versatile cbu
Cbu 89 - air delivered minefield
Cbu 97 - armor on the move killer
State the primary purpose of detectors in IR air to air missiles
Convert modulated ir energy to an electrical signal
State the primary purpose of reticles in ir air to air missiles
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
State the primary characteristics of beam rider
Missile stays in the main beam of the launching aircraft radar
State the characteristics of semiactive missiles
Aircraft radar tracks the target while the missile homes in on the reflected energy
State the characteristics of active missiles
Missile has its own transmit and receive radar
List the factors that impact forward quarter max employment range for air to air missiles
Detection
Motor
Drag
Guidance life
What is f pole
Range from fighter to target when missile impacts target
What is a pole
Range from fighter to target when active missile acquires target with its own radar
What is min abort range
Min range from threat aircraft that a drag can be accomplished to kinematicly defeat missile
What is min notch range
Min range that notch from threat aircraft can be performed
List each nuc effect and provide example of each to structure and people
Blast - people collapsed lungs, structure collapse
Thermal - people flash blinded, structure on fire
Radiation - people sickness and death
How is nuclear detonation achieved in fission
Gun assembly/ implosion brings u235 or pu239 to supercriticality
Neutrons are injected into supercritical material
Fission chain reaction occurs
Bomb case ruptures, nuclear detonation
How does a fusion weapon produce detonation with example
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
List nuclear burst profiles
Air burst - enhances thermal / blast
Ground burst - enhances radiation
Subsurface burst - enhances ground shock
Match the following to description B61 B83 W80-1 W78
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
Describe LGB concept of operation
Released ballistically, operator lases target, munition guides to laser spot. Meeker and designator must maintain Los with target throughout weapons tof.
Advantages of LGB (list 3)
Standoff from AAA Simple to use Man in the loop to impact Accurate weapon with real time hit assessment Can hit moving targets
Disadvantages of LGB (list 3)
Shorter standoff range to boosted weapons Requires close in designator support Los for weapon and designator required Weather must support guidance Battlefield obscurants
Concept of operation for gps aided munitions
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
Advantages of gps munitions (list 3)
Standoff from Aaa and short range Sam
Adverse weather/ battlefield obscurant capable
Multiple delivery platforms
Multiple weapons and aim points per pass
Disadvantages of gps
No man in the loop after release
Gps jamming impedes guidance
Cannot hit moving targets
Factors determining delivery accuracy of gps bombs
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
**Advantages of gp bombs
Plentiful
Good explosive weight
Good blast/frag
Building block for guided weapons
**Define aspect angle
From tgt to attacker, starts at targets tail, attacker heading irrelevant
**Define hca
Heading crossing angle…angular difference between target and attacker noses
**Define Los
Line of sight…attackers nose to target
**Disadvantages of semiactive guidance
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
**agm 65 concept of operations
Ir/eo sensor slewed to tgt
Tgt id’d and missile visually locked
Pilot fires missile
Missile guides to tgt
**Tactical missile advantages
Precision
Standoff from small arms
Simple to use
Moving tgts
**tactical missile disadvantages
Weather
Battlefield obscurants
Small warheads
