Abstract

An unmanned, self-propelled minesweeping apparatus, capable of sweeping atubstantial depths, is described, comprising a torpedo-like submarine vehicle that deploys and tows a string of explosive mooring cable cutters terminating in a sea anchor. The sea anchor serves as a carrier for the cutters and the towline and, after ejection as a package from the vehicle, is actuated to an expanded condition and displaces the cutters and coils of towline therefrom.
