Test 3 All Flashcards
(40 cards)
Describe 3 ways to enhance nuclear weapons effects
Airburst - fireball does not touch the ground
(Blast and thermal enhanced, residual radiation reduced)
Ground burst - fireball touches the ground
(Residual radiant enhanced)
Subsurface blast - underground/underwater detonation. (Ground shock enhanced)
Describe the following:
B61
B86
AGM86 (ALCM)
B61 - fighter and bomber deliverable; smaller weapon
B86 - bomber only deliverable; larger weapon
AGM86 - B52 only, air launched cruise missile
Thermal radiation effects on people
Flash blindness causing permanent damage to the retina
Flash burns, 2nd degree burns out to 15 miles, 3rd degree burns out to 8 miles
Thermal effects on structures
Threshold ignition of light flammable material like paper out to 10 miles
Extensive fire damage out to 8.5 miles
Thermal radiation mitigation measures
Protective enclosures, thermal protective coatings, nonflammable clothing, tools and equipment
For aircrew, eye protection, cockpit canopy shields and maintain prescribed weapon delivery profiles
Effects of a nuclear detonation
Blast
Thermal
Radiation
What is the purpose of detectors
Convert MODULATED IR energy to an electrical signal
What is the primary purpose of a reticle
Modulate IR energy via opaque and clear tracking windows and varies output of the electrical signal sent to the GCS based upon where the IR energy hits the reticle
Characteristics of semiactive guidance
Aircraft radar tracks the target while the missile homes in on the reflected radar energy
Has a radar receiver but no transmitter
characteristics of active guidance
Missile has its own transmit and receive radar
Missile has onboard inertial guidance system
Active guidance advantages/disadvantages
Advantages:
- Accurate at long range
- difficult to jam
- launch and leave capability
- multitargeting
Disadvantages:
- complex
- jamming against TTR may be effective prior to missile radar acquiring target
Semiactive guidance advantages/disadvantages
Advantages:
- accurate at longer ranges
- resistant to EA
- can be guided almost immediately after launch
- can compute its own course corrections
Disadvantages:
- required reference Doppler be sent to missile before launch
- must maintain lock on target Doppler
- missile that required lock on before launch limits max range
- shooter must maintain target lock thruout TOF
What affects forward quarter performance max range
Target detection
Motor
Drag
Guidance life
What affects forward quarter performance min range
LTE delays
Arming delays
Fuzing
Guidance enable
Missile maneuverability
Gimbal limits
Define F Pole
Range from fighter to target when missile impacts target
Define A pole
Range from fighter to target when active missile acquires the target with its own radar and requires no support from launching aircraft
Define Minimum Abort Range (aka E-Pole)
The minimum range from a threat aircraft that a drag can be accomplished to kinematically defeat any missile the threat aircraft could have launched
**Define Minimum Notch Range (aka N-Pole)
The Minimum range from a threat aircraft that a notch maneuver can be accomplished
**List the 5 basic weapon effects
Blast/Shock
Fragmentation
Cratering/penetrate
Armor penetration
Incendiary
List the general purpose (GP) bomb characteristics
Cast steel casing
Nose fuze and tail fuze wells
Aerodynamic body shape
50% explosive weight
“Jack of all trades”
Rule of thumb for MK82 penetration
1 ft
Rule of thumb for MK84 penetration
3 ft
Describe penetration bomb characteristics
Explosive weight: 10-30% total weight
Heavy, forged-steel case to prevent breakup
Tapered nose and parallel sides to prevent ricochet
Tail fuze well only to ensure nose structural integrity
Best penetration capability
Rule of thumb for BLU109 penetration
6 ft
