the same compartments with or near radio apparatus or antenna leads. Induced currents might ignite the motor. Do NOT fire rocket motors when the propellant temperature is outside the safe-firng temperature limits specified on the motor tube. If a rocket motor is dropped and any portion impacts on a hard surface after falling 2 feet or more, do NOT use it. Cracks or breaks in the grain increase the carefully calculated burning area and cause excessive internal pressure buildup, which can cause the motor to blow up after ignition. Stow high-explosive heads and fuzes (except fuzes that are permanently installed in the head) separately in the same manner as high-explosive projectiles. Ready-service stowage of assembled rockets is authorized for the 2.75-inch and 5.0-inch aircraft rockets according to NAVSEA OP 4 and NAVSEA OP 5. A fuze is relatively sensitive and must be handled with care to avoid extreme shock that might cause damage. Conduct fuzing, unfuzing, assembly, or disassembly operations of all types of ammunition away from other explosives and vital installations. Only the minimum number of persons and rounds required should be in the vicinity. The ideal situation is to permit work on only one round at a time. This work should be done on a deck or at some other location remote from all magazines, ready stowage, explosive supplies, or vital installations. Examination of the exterior of some fuzes will not show if they are armed. If, for any reason, you think a fuze might be armed, the fuze should be treated as an armed and sensitive fuze. You must NOT attempt to remove it from the rocket head. The complete fuzed round should be disposed of according to current directives. When available, explosive-ordnance- disposal (EOD) personnel should dispose of such rounds. CAUTION NEVER attempt to remove a base fuze from a rocket head. You should NOT tamper with (or attempt to repair) any parts of the round. If the round is damaged or defective, remove the head from the motor and mark the defective part for return to the issuing agency. Disassembly or alteration of rocket components is NOT authorized except under specific instructions from Naval Air Systems Command. Fuzes and/or warheads dropped 5 feet or more onto a hard surface and rockets that have been accidentally released from aircraft launchers upon aircraft landing must be disposed of according to current directives. If a loaded launcher is dropped, you should NOT use it until the launcher tubes, latching mechanisms, and rockets are inspected for damage. Rocket launchers should NOT be suspended from a bomb rack that does not have independent ignition and REVIEW NUMBER 5 ANSWERS TO QUESTIONS Q1. THROUGH Q6. A1. A2. A3. A4. A5. A6. The center section of the launcher that houses or supports all other components of the launcher. RF barriers are used on 2.75-inch rocket pods to prevent entry of electromagnetic radiation into the igniter circuit. The components that are common to rocket launcher packages are as follows: fairings, breaker switch, mode selector switch, and intervalometer. The breaker switch, found on all rocket launchers, prevents loaded rockets from firing. The detent pin in the rocket launcher safe/arm device is removed immediately before takeoff. The weight, depending on configuration, of a fully loaded LAU-10 rocket launcher is approximately 500 to 550 pounds. 2-30
