Abstract
In a submarine weapon, particularly for combating submarines, a rocket engine with continuous rocket thrust is utilized as the submarine drive unit. An actively locating, acoustic target seeking device is provided for target detection and target pursuance, the ranging frequency of which is selected so that the echo level to be expected from its detection range lies above the noise level of the rocket engine.
