and Gator weapons. The FMU-140/B is a self- powered doppler radar device acting as a radar altimeter. Arming times and functioning altitudes are variable and are preflight selectable on the fuze faceplate, located on the side of the fuze. In the proximity mode, if the preselected altitude is reached before the fuze has had time to arm, or the dispenser is released below the pre-selected altitude, the fuze will have the potential to function anytime after arming. If the fuze has not functioned by the time it reaches an altitude of 300 ±25 feet, it will function at that time. Q1. Q2. Q3. Q4. Q5. Q6. Q7. REVIEW NUMBER 5 All electric capability for Mk 80 with either conical or retarding fins, thermally protected bombs, and laser-guided bombs is provided by ________________________. No unusual RADHAZ precautions are taken when using Mk 344 or Mk 376 fuzes because they are classified as__________. Name the electric fuze that is used for retarded delivery of the Mk 80 (series) bomb. List the functions of the Mk 31 safety device. What is the purpose of the Mk 122 Mod 0 arming safety switch ? What is the purpose of the Mk 43 Mod 0 target detecting device? What is used to power the internal circuitry of the TDD? AIRCRAFT BOMB AMMUNITION AND ASSOCIATED COMPONENTS LEARNING OBJECTIVE: Identify the purpose and types of aircraft bombs, the safety procedures to be followed during bomb shipment, and the methods used to carry bombs. Aircraft bombs are released over enemy targets to reduce and neutralize the enemy’s war potential. This is done by destructive explosion, fire, nuclear reaction, and war gases. Aircraft bomb ammunition is used strategically to destroy installations, armament, and personnel; and tactically in direct support of our land, sea, and air forces engaged in offensive or defensive operations. For safety reasons, some bomb ammunition is shipped and stowed without the fuzes or arming assemblies and associated components installed. This ammunition must be assembled before use. Other types, such as cluster bomb units (CBUs), are shipped and stowed as complete assemblies, with fuzs or arming assemblies and associated components installed. Bombs are designed to be carried either in the bomb bay of aircraft or externally under the wings or fuselage. The general characteristics and basic principles of operation of bomb ammunition and its associated components are described in this chapter. Bombs assembly procedures are discussed in chapter 13 of this manual. GENERAL-PURPOSE BOMBS AND FIN ASSEMBLIES LEARNING OBJECTIVE: Identify the purpose and use of general-purpose bombs to include shipping configuration, fuze wells and charging circuits, suspension lugs, arming wire assemblies, and fin assemblies. Low-drag, general-purpose (LDGP) bombs are used in most bombing operations. Their cases (bomb body) are aerodynamically designed, relatively light, and approximately 45 percent of their weight is made of explosives. General-purpose bombs may use both nose and tail mechanical or electric fuzes and conical or Snakeye fins. The general-purpose bombs currently in use are the LDGP Mk 80 (series).
