2W151 Set B Vol 2
Nuclear bombs and high-drag GP bombs have what common characteristics, -
✔️✔️They're both normally equipped with parachutes to produce the high-drag effect
and they may be loaded on the same bomb racks on most aircraft.
What are boosters for, - ✔️✔️Used to adapt small diameter fuzes to large diameter
nose and tail fuze wells. This component also serves to boost the explosive train
between the fuze and the bomb
What type filler is in GP bombs?, - ✔️✔️Tritonal
What's the difference between blast bombs and penetration bombs, - ✔️✔️Blast
bombs have light cases and poorer penetration whereas penetration bombs have cases
hard enough to penetrate concrete and armor plating
A shaped charge bomb is designed to attack what type of targets, - ✔️✔️Heavily
armored targets like tanks or ships
How accurate are precision-guided GP bombs, - ✔️✔️From 1 to 10 meters depending
on the guidance system
Why must kinetic energy penetrators be handled carefully even if they contain no
explosive, - ✔️✔️Many of their delivery systems do contain explosives or other
hazardous components
What bomb class usually causes smoke and a small flash upon impact, - ✔️✔️Practice
bombs.
Name the six components of a typical bomb., - ✔️✔️(1) The bomb body.(2)
Suspension lugs.(3) Fin assemblies.(4) Arming wire assembly.(5) Bomb fuzes.(6)
Adapter boosters
The bomb body of a general-purpose bomb is usually made of what type material, -
✔️✔️Heavy cast iron about ½-inch thick
Fragmentation bomb bodies are made of what type material, - ✔️✔️Spirally wound
spring steel that breaks into fragments when the bomb is detonated
A 2000 pound bomb has what suspension lug spacing, - ✔️✔️Thirty inches.
,What is the purpose of arming wires, - ✔️✔️To keep the fuzes from arming until the
bombs are released from the aircraft
What do initiators provide, - ✔️✔️Electrical power and interconnection cables to the
nose and tail fuzes
What are sensors designed to do, - ✔️✔️Sense the proper altitude for the detonation of
a weapon via a radio frequency or Doppler radar
The explosive weight of most GP bombs is what percentage of the total weight, -
✔️✔️Between 35 percent and 55 percent
How are bombs identified, - ✔️✔️By the model number lot number and/or serial
number and painting or marking
Why is it important to keep track of serial numbers of munitions being flown on aircraft?,
- ✔️✔️So that the munitions items maintenance or service history can be tracked
What is the purpose of painting and marking bombs, - ✔️✔️They're painted mainly to
prevent corrosion and they're marked for identification
What do the color bands painted on munitions identify, - ✔️✔️The primary explosive
component used in the munition
How is the MK 82 high-drag bomb's flight slowed, - ✔️✔️By an air-inflatable retarder
What GP bomb is used to make the BSU-49 AIR high-drag bomb?, - ✔️✔️MK-82.
What bomb was designed to augment and replace the MK-84, 2,000-pound GP bomb?,
- ✔️✔️BLU-109/B
How many fuze wells are in the BLU-109/B, - ✔️✔️One located in the tail.
The BLU-109/B can be used with what GBU configurations, - ✔️✔️GBU-10/15/24/27
How much does the BLU-113A/B weigh, - ✔️✔️4500 pounds
What components make up modular guided bombs, - ✔️✔️A standard GP bomb body,
a target detecting device modular control unit and airfoil group with a cruciform wing
design
, What is the prime advantage of laser guided munitions?, - ✔️✔️Their high degree of
accuracy. These munitions can reasonably be expected to strike within 1 to 3 meters of
their designated target
How close to its target can a GPS/INS guided munition be expected to strike, -
✔️✔️Within 10 meters of its target
What is the main drawback to the EGBU hybrid system using both laser guidance and
GPS/INS systems, - ✔️✔️The main drawback to this system is in its complexity.
Having both systems in a single package makes the weapon more expensive and more
complicated to load and maintain than a weapon utilizing either guidance system
independently
What GP bomb is used as the warhead for the GBU-12?, - ✔️✔️The MK-82
What two munitions may be used as the warhead for a GBU-15?, - ✔️✔️A BLU-109 or
a MK-84 2000-lb bomb
What is the purpose of the target-detecting devices on the GBU-15, - ✔️✔️They're
used for target acquisition and lock on before/after the weapon is released from an
aircraft
What warhead is used for the GBU-24A/B, - ✔️✔️BLU-109/B
What is the purpose of the hardback assembly and lug sleeves supplied with the GBU-
24A/B, - ✔️✔️They provide more distance between the bomb and bomb rack
What warhead is used for the GBU/EGBU-28, - ✔️✔️The GBU-28 is a conventional
munition that exclusively uses the BLU-113 series 4500 lb penetrating warheads.
What warheads are compatible with JDAM tail kits, - ✔️✔️MK-82 MK-83 MK-84 BLU-
109 BLU-110 and BLU-117 warheads.
What two components comprise a CBU, - ✔️✔️A dispenser and a quantity of small
bomblets or mines inside it.
After a CBU-87 -89 -105 or -107 is released from an aircraft, how does the dispenser
open, - ✔️✔️The fuze functions and three linear shaped charges cut the dispenser into
thirds and remove the tail section
What forces the CBU-87/89/105/107 apart to release the submunitions, - ✔️✔️The air
stream
The BLU-91/B submunition is used against what type of target, - ✔️✔️Tanks.
