FIELD: shipbuilding.

SUBSTANCE: invention relates to the field of underwater shipbuilding, namely, to the submarine device. Submarine with an electro-hydraulic launcher includes an outer housing, a main housing and an electrohydraulic launcher comprising at least one launching tube, a pulse tank installed in the outboard space between the housings, with the vane pump, inlet for water supply from outboard space and outlet connected to launching pipe, and pump electric motor.
