The destructor mine consists of an LDGP aircraft bomb and a Mk 75 modification kit. The Mk 75 modification kit (fig. 1-29) contains the Mk 32 arming 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. With the Mk 75 kit installed, aMk 82 LDGP bomb (500 pounds) becomes a Mk 36 DST, a Mk 83 LDGP bomb (1,000 pounds) becomes aMk 40 DST, and aMk 84 LDGP bomb (2,000 pounds) becomes aMk 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.
