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
