AVIATION ORDNANCE UNIT 4 EXAMS COMPLETE
QUESTIONS AND CORRECT ANSWERS|AGRADE
Characteristics of Ammunition - correct answer-
Insensitive, powerful enough to produce damage, and must be able to remain stable over an extende
d period.
2 General Classes of Explosives - correct answer-High and Low explosives
High Explosive - correct answer-
virtually instantaneous, rapid expansion of large volumes of gas and heat, causing a very high press
ure and widespread shattering effect. "Big Boom"
Low Explosive - correct answer-Ignited by flame and burns/combusts slowly. Do not explode.
2 Types of Explosive Composition - correct answer-Explosive Mixtures and Explosive Compounds
Explosive Mixture Characteristics - correct answer-
two or more distinct substances. Prepared and mixed in varying proportions.
Explosive Compound Characteristics - correct answer-
Uniform in structure and composition. Molecules contain the oxygen, carbon, and hydrogen for com
bustion.
Gun Ammunition Types - correct answer-Fixed: all together
Separated: propelling charges and projectiles are separate.
Separate Loading: projectile and primer are separate sections.
Bomb Ammunition - correct answer-Thin walled containers loaded with high explosives
Rocket Ammunition - correct answer-Motor, warhead, and fuse assembly.
,Guided Missile Ammunition - correct answer-
Same characteristics as rocket ammunition, contains guidance and control sections.
Pyrotechnic Ammunition - correct answer-
Mixtures of oxidizing agents designed to produce illumination, colored lights, and smoke.
3 Types of Pyrotechnics - correct answer-Signaling, Illuminating, and Marking.
Service Ammunition - correct answer-tactical, used in times of war.
Non-Service Ammunition - correct answer-designed for training, may be modified.
Types of Non-Service Ammunition - correct answer-
Practice/Training, Dummy Drill/Inert, Exercise/Recoverable, Blank, and Unserviceable.
Practice/Training Ammunition Characteristics - correct answer-
May or may not contain explosives. Actually launched or dropped. Expendable or Recoverable.
Dummy Drill/Inert Ammunition Characteristics - correct answer-
Completely inert. Used for display, testing, and weapons-handling operations.
Exercise/Recoverable Ammunition Characteristics - correct answer-
Modified service ammunition. Used for training. May contain spotting charges and/or pyrotechnics.
Blank Ammunition Characteristics - correct answer-
Service ammunition with no projectile. Used for simulated firing and signaling.
Unserviceable Ammunition Characteristics - correct answer-
Reclassified due to changes in service/shelf life or found to be damaged.
3 Ways to Identify Ammunition - correct answer-Painting, Marking, and Lettering.
Non-Significant Paint Colors - correct answer-Olive drab, black, and white.
, Significant Paint Colors - correct answer-Yellow: high explosives
Brown: low explosives
Blue: inert explosives.
What is Marking? - correct answer-Application of colored spots, bands, or symbols on ammunition.
What is Lettering? - correct answer-
Application of words, letters, abbreviations, or numbers of ammunition. NALC/DODIC.
Mark and Modification - correct answer-Mark: Arabic numeral that represents the basic design.
Modification: Follows the mark number and represents a less than major change in design.
NALC/DODIC - correct answer-
Naval Ammunition Logistics Code/Department of Defense Identification Code: 4 digit long alphanu
meric code used to identify ordnance.
Ammunition Lot Number - correct answer-
quantity of ammunition assembled from uniform components under similar conditions.
CAD - correct answer-Cartridge Actuated Device: provides gas pressure to launch or release stores.
Purposes of CAD - correct answer-
Provide power to drive cables, shrouds, or shroud cutting devices. Provide energy for the initiation o
f large explosive devices.
3 Methods of Actuation - correct answer-Percussion, Electrically, and Sympathetically.
Percussion Actuation - correct answer-
a striker or firing pin strikes the primer of a cartridge igniting a charge. Tap-boom.
Electrically Actuated - correct answer-
contact button or squib receives an electrical charge that ignites the charge. Zap-boom.
