For detailed information concerning aircraft launch accessories, you should refer to the U.S. Navy Aircraft Torpedoes Accessories and Trajectory Data and Quality Assurance Test and Inspection Plan for Installation of Torpedo Mk 46 Launch Accessories, NAVSEA SW512-AO-ASY-010. OTTO FUEL II Otto  Fuel  II  is  the  propellant  for  the  propulsion system of the Mk 46 (all Mods) torpedo. Otto Fuel II is first sprayed under pressure into a combustion chamber where it is ignited. The exhaust gases from the burning fuel  are  used  to  drive  the  torpedo  engine.  The  major advantage  of  this  system  is  the  short  turnaround  time required for exercise weapons. Otto  Fuel  II  is  a  stable,  liquid  monopropellant composed   of   a   nitrate   ester   in   solution   with   a desensitizing  agent  and  a  stabilizer.  It  is  a  bright  red, free-flowing,  oily  liquid  that  is  heavier  than  water. (NOTE: When in a thin layer, such as a spill, stain, or leak, Otto Fuel II is a yellow-orange color.) Otto Fuel II is noncorrosive. It has an extremely low vapor pressure, minimizing  explosive  and  toxic  hazards.  Otto  Fuel  II can detonate, but the conditions and stimulus required are so extreme that it is considered a nonexplosive. The propellant   has   a   high   flash   point   and   other   safety characteristics.  It  is  classified  as  a  low  fire  hazard material. The ingredient of medical concern in Otto Fuel II is the  nitrated  ester.  Nitrated  esters  are  known  for  their acute   effects   on   the   human   body.   Symptoms   of exposure to Otto Fuel II include the following:   Headache   Dizziness   Drop in blood pressure   Nasal congestion NOTE: Depending upon the sensitivity of the individual, a temporary symptom-free tolerance may develop during the remainder of the   working   period.   After   exposure   to   a vapor-free  environment,  the  first  contact  with Otto    Fuel    II    vapors    often    causes    these symptoms to recur. A stowage space is specifically designated for each type  of  torpedo  stowed  aboard  a  combat  ship.  When handling Otto Fuel II, at least two crewmembers should handle  the  fuel.  All  personnel  must  know  the  general characteristics of Otto Fuel II, the safety precautions for handling  the  fuel,  and  protective  equipment  required. To avoid hazardous situations when handling Otto Fuel II, personnel should be well trained and supervised. For further information concerning Otto Fuel II, you should refer  to  Otto Fuel II Safety, Storage, and  Handling Instructions, NAVSEA S6340-AA-MMA-010. REVIEW NUMBER 1 Q1. What is the primary weapon used for antisubmarine warfare? Q2. List the Mk 46 configurations. Q3. When   the   Mk   46   is   used   in   the   exercise configuration, what exercise head is used? Q4. After  launch,  what  equipment  stabilizes  the torpedo during its descent into the water? Q5. List the air stabilizers used for (a) fixed-wing and (b) rotary-wing aircraft. Q6. Torpedoes are suspended from bomb racks or shackles    by    Mk    78    Mod    0    or    Mod    1 suspension  bands.  How  do  the  suspension bands release when the torpedo is launched? Q7. What  propellant  is  used  in  the  propulsion system of the Mk 46 torpedo? Q8. Because  Otto  Fuel  II  has  a  high  flash  point, low vapor pressure, and is noncorrosive, it is classified as ___________. Q9. List  the  symptoms  you  might  exhibit  if  you were exposed to Otto Fuel II. Q10. For  safety  reasons,  how  many  crewmembers should  be  present  when  handling  Otto  Fuel II? AIRCRAFT-LAID MINES LEARNING  OBJECTIVE:  Identify  aircraft- laid mines and recognize their classifications. Describe  aircraft-laid  mine  components  and identify operational aircraft mines. Naval  mines  are  used  in  offensive  or  defensive mining    operations.    The    primary    objective    is    to effectively defend or control vital straits, port approaches,  convoy  anchorage’s,  and  seaward  coastal barriers. Aircraft  mine  delivery  is  the  principal  method  of making  large-scale  mining  attacks  on  enemy  coastal and  port  areas.  Aircraft-laid  mines  are  usually  carried and dropped in the same way as bombs, but they have 5-6
