describe a given mine; for example, an air-laid, pressure-fired, bottom mine or an air-laid, magnetic-fired, moored mine. Table 5-1 provides a list of the air-laid mines currently in use. REVIEW NUMBER 2 Q1. Mines classified by their intended use are classified as __________________. Q2. What  mines  are  fully  loaded  with  explosives and designated for use in wartime? Q3. What mines is classified by the position they take in the water after being laid? Q4. The   effective   depth   of   a   bottom   mine   is controlled by ____________________. Q5. Moored mines are stabilized by what means? Q6. List  the  classifications  of  influence-actuated mines. MINE COMPONENTS The components used in a mine vary, depending on the type of mine and its specific use. In addition to the mine  case  and  explosive  system,  mine  components provide mine arming, target sensing, actuation, laying control,  countermeasure  resistance,  firing  power,  and sterilization. Exercise components are used in exercise (recoverable) mines. REVIEW NUMBER 1 ANSWERS A1. The  Mk  46  torpedo  is  the  primary  weapon used for antisubmarine warfare. A2. The  Mk  46  configurations  include  warshot and exercise. A3. When   the   Mk   46   is   used   in   the   exercise configuration,  the  Mk  85  and  Mods  exercise head is used. A4. After  launch,  the  air  stabilizer  stabilizes  the torpedo during its descent into the water. A5. Fixed-wing aircraft use Mk 28 Mod 2 or Mod 3 air stabilizers, and rotary-wing aircraft use Mk 31 Mod 1 air stabilizers. A6. Torpedoes are suspended from bomb racks or shackles    by    Mk    78    Mod    0    or    Mod    1 suspension bands. As torpedoes are launched from  the  aircraft,  release  wires  unlatch  the suspension  bands,  letting  them  break  away from the aircraft. A7. Otto  Fuel  II  is  the  propellant  used  in  the propulsion system of the Mk 46 torpedo. A8. Because  Otto  Fuel  II  has  a  high  flash  point, low vapor pressure, and is noncorrosive, it is classified as a low fire hazard material. A9. If you were exposed to Otto Fuel II, you might exhibit   the   following   symptoms:   headache, dizziness,  blood  pressure  drop,  and/or  nasal congestion. 5-8 MINE DESIGNATION WEIGHT CLASS TYPES OF ACTUATION POSITION IN WATER RETARDED Mk 55 Mk 62 Mk 63 Mk 64 Mk 65 1000 lb 500 lb 1000 lb 2000 lb 2000 lb Influence Influence Influence Influence Influence Bottom Bottom Bottom Bottom Bottom Parachute Fin Parachute Parachute Parachute Table 5-1.—Air-laid Mines Currently in Use
