device, Mk 59 booster, Mk 42 firing mechanism, and all necessary hardware (less battery and fin assembly) to convert an LDGP bomb to an air-laid mine. The firing mechanism of the Mk 42 arming device requires the use of a Mk 95 battery, which must be installed during assembly procedures. REVIEW NUMBER 5 ANSWERS A1. Normally, low-drag general-purpose (LDGP) bombs are used in bombing operations. Currently, Mk 80 (series) LDGP bombs are used. A2. Bombs are shipped on metal pallets because of their increased capacity and for grounding purposes over wooden pallets. A3. The  Mk  15  fin  is used with the Mk 82 bomb in either a low-drag or high-drag configuration. A4. The ADU-320/B adapter is used to mate the MAU-91A/B fin to the Mk 83 bomb. A5. The    three    modes    of    delivery    used    with Snakeye   fins   are   the   retarded   mode,   used during low-level bombing; nonretarded mode,  in  which  the  weapon  free  falls  to  the target;    and    the    in-flight    selected    mode (pilot  option),  where  the  pilot  selects  either the retarded or   nonretarded   mode   of delivery. REVIEW NUMBER 6 ANSWERS A1. Laser-guided bombs detect a target illuminated by a laser beam. A2. Electrical tail fuzes are used in laser-guided bombs. A3. The wing assembly is mounted on the aft end of    the    bomb    body    to    add    aerodynamic stability and lift for in-flight maneuvering. With the Mk 75 kit installed, a Mk 82 LDGP bomb (500 pounds) becomes a Mk 36 DST, a Mk 83 LDGP bomb (1,000 pounds) becomes a Mk 40 DST, and a Mk 84 LDGP bomb (2,000 pounds) becomes a Mk 41 DST. The  Mk  36  and  Mk  40  DSTs  can  be  dropped  in  the retarded    or    nonretarded    mode    of    delivery.    The installation   of   a   conical   fin   provides   nonretarded (free-fall) delivery only. The installation of a Snakeye fin assembly provides the pilot with the in-flight option of  releasing  the  DST  in  the  retarded  or  nonretarded mode. The Mk 41 DST is configured with a conical fin for   nonretarded   delivery   only.   The   standard   LDGP bomb  markings  plus  white  stripes  (fig.  1-30)  identify DSTs. Additional information on DSTs may be found in Destructor Mk 36, 40, and 41, all Mods, NAVSEA OP 3529. REVIEW NUMBER 7 Q1. What modification kit is used to make LDGP bombs into destructor (DST) mines? Q2. Name  the  bomb  used  to  make  the  Mk  40 destructor. Q3. Name the DST that can only be dropped in the nonretarded mode. ANTITANK BOMB CLUSTER MK 20, CBU-99, AND CBU-100 LEARNING OBJECTIVE: Identify the purpose and use of the various configurations of the Mk 20, CBU-99, and CBU-100 antitank bomb clusters. Describe the function of the Mk 118 Mods 0 and 1 antitank bomb. 1-33 Figure 1-30.—DST identification markings.
