Bombs/weaponeering

Question 1

What are penetration bombs good/used for?

Answer 1

Penetrating layered targets. Depending on build of bomb, layers of steel, concrete and earth can be penetrated

Question 2

Good Rule of Thumb for penetration of bombs with examples

Answer 2

GP bombs penetrate between 1’ (MK 82) and 3’(MK 84)

Penetration bombs penetrate between 6’ (Blu-109, 2000lb) and >22’ (Blu-113,5000lb)

Question 3

5 HE weapons effects

Answer 3

Blast/schock-blow down walls, rupture eardrums
Fragmentation-spray with shrapnel (soft targets)
Cratering-dig holes, puncture structures
Armor penetration-puncture stew and concrete
Incendiary-burn things

*effects are present in all warheads to varying degrees based on purpose

Question 4

General Purpose Bomb characteristics

Answer 4

Cast steel casing
50% explosive weight
Aerodynamic body shape
Jack of all trades weapon
Nose AND tail fuzes

Question 5

What is the CBU-97?

Answer 5

Cluster bomb unit that consists of a normal bomb body with 10 Blu-108B skeet delivery vehicles carrying 4 skeets per vehicle

Best armor on the move killer(tanks), contains smart bomblets with sensors

*cluster bombs are typically used for Area targets

Question 6

Purpose of an IR missile

Answer 6

To exploit a targets IR energy

Question 7

List four components of an IR system

Answer 7

Detector-senses target
Optics system-tracks target
Flight profile-Hit target
IRCCM-ignore flares

Question 8

What is the purpose of a detector?

Answer 8

Convert modulated IR energy to an electrical signal, sense the target

*detector is important because the capability of the missile is limited by the detector

Question 9

What is the purpose of the reticle in the detector?

Answer 9

For tracking corrections, the reticule modulates the IR energy for the detector 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

Question 10

How does an AM reticle work?

Answer 10

Measures the AMOUNT of IR energy passing through each individual transparent spoke of the reticle

Question 11

How does and FM reticle work?

Answer 11

Measure how much TIME IR energy spends on each individual transparent spoke of the reticle

Question 12

What are the 3 steps to IRCCM?

Answer 12

Detect- a sharp rise in IR energy or change in Kinematics

Confirm-check a sharp increase in intensity in another IR band

Counter-response

Question 13

What are some responses and IRCCM missile might have in response to target protection?

Answer 13

FOV- small FOV allows for the missile to never see the flare

Memory-allows the missile to continue looking in the direction the aircraft was tracking, ignoring falling away flares

Spectral- can see in multiple wavelengths

Kinematics- biases forward moving seekers

Question 14

Advantages and disadvantages of CBU’s

Answer 14

Advantages

• area targets, blanketing large targets with effects
• capability against moving targets

Disadvantages

• political constraints
• wind attack axis sensitive, all munitions now guided

Question 15

What is the Concept Of Operations of a LGB?

Advantages and disadvantages

Answer 15

Target is designated with a laser, weapons detects reflected energy

Advantages: simple to use, stand-off provided for small arms and AAA, maintains man-in-the-loop to impact, accurate weapon with real-time hit assessment

Disadvantages: requires close in designator support, LOS for weapon and designator must be maintained, wx and battlefield obscurant may impede guidance

Question 16

Describe the concept of operations of a GPS aided munition? Advantages and Disadvantages

Answer 16

GPS aides weapons are released and autonomously guide to its target regardless of weather. Guidance is accomplished via coupling with an accurate GPS and INS

Advantages: greater standoff from small arms, AAA and short SAM ranges, adverse wx and battlefield obscurant capable, multiple delivery platforms and multiple targeting capable

Disadvantages: no man in the loop for backup, GPS jamming may impede guidance, cannot hot loving targets

Question 17

What determines the accuracy of a GPS guided munitions?

Answer 17

Accuracy is determined by

Navigation errors: position handoff and IMU velocities, GPS errors
Guidance and control errors: weapon responsiveness to guidance commands
Target and Location Errors: accuracy of target coordinates

Equation=sqrt of [(nav^2)+G&C^2)+(TLE^2)]

Question 18

What are the types of Radar guided missiles?

Answer 18

Active - missile has its own transmit and receive radar

Semi active- aircraft radar tracks the target while the missile homes in on reflected energy

Question 19

What are radar guided missiles used for?

Answer 19

Good for long range and BVR targets, moving targets and GPS denied environments
