The UKSM anchored mine (УКСМ) was developed in the Design Bureau of the Kuybyshev Machine-Building Plant in 1960 from the KSM mine. The abbreviation U stands for Unified (Унифицированная) and it is basically a KSM mine adapted to use different fuzes (in addition to the original electric one from the KSM mine, a new one with a 5-element antenna, an acoustic one from the KB-KRAB mine, and a hydro-locating NGV one). The characteristics of the mine vary according to the igniter used.
Basic tactical and technical data:
