„Toczek” explosive charges

Product description

A system of remotely and wirelessly initiated explosive charges, consisting of three types of combat charges that differ in explosive mass and methods of deployment in the sea near target objects. Type A charges are intended for the detonation of naval mines, while Type B charges are designed for the effective destruction of mine initiation mechanisms—both types significantly reduce the need to involve divers in the threat neutralization process, as they are transported and deployed by remotely operated underwater vehicles (ROVs) or autonomous underwater vehicles (AUVs). The smallest charge, designated as Type C, is carried by mine clearance divers and attached to mooring lines and chains of moored mines, which are severed by the explosion, causing the mine to surface.

The explosive charges are equipped with a universal, standardized fuze integrated with a hydroacoustic receiver, compatible with all types of “Toczek” charges. Charge initiation is performed by generating coded hydroacoustic signals in the water column from a transmitting device. Each fuze features a unique identification code and a multi-level system of mechanical and hydrostatic safety mechanisms. Programmable arming delay and neutralization capability enable controlled detonation, while the low magnetic signature reduces charge detectability.

The Toczek charge system is equipped with a dedicated device enabling comprehensive testing of all fuze parameters.
