The conflict in Southeast Asia saw the introduction of a different kind of mine called a Destructor (DST). Destructors Mk 36, Mk 40, and Mk 41 are aircraft-laid bottom mines which use General Purpose (GP) Low-Drag Bombs Mk 82, Mk 83, and Mk 84, respectively as the mine case and explosive charge. The bombs are converted to mines with the installation of a kit of modular components that comprise a mine-type arming, detector, and firing system. The kit contains an arming device, an explosive booster, a magnetic-influence firing mechanism and associated hardware. The arming device and booster install in the bomb's nose cavity and the firing-mechanism (with battery) installs in the bombıs tail cavity. The same kit of components and method of assembly are used for each one of the destructors, but the kits are available in a number of configurations, each with a different circuitry to meet a variety of operational requirements. It should be noted, however, that since the bomb cases are small, medium, and large, they require different flight gear. DSTıs became the first mines to be used on both land and sea. When dropped on land, they bury themselves in the ground on impact, ready to be actuated by military equipment, motor vehicles and personnel. When dropped in rivers, canals, channels, and harbors, they lie on the bottom ready to be actuated by a variety of vessels including war ships, freighters, coastal ships, and small craft.
