This form of torpedo solves the problem of high underwater drag by means of the supercavitation effect,[1][3] where underwater at a velocity of around 180 km/h a cavity filled with steam surrounds the moving object.[3] Only the tip is in contact with the water,[3] as such the frictional resistance is greatly reduced.[3] The propulsion of such a torpedo can no longer be done by a propeller but requires a rocket engine.
To steer, this torpedo has a pivoting head segment. If the torpedo rises or falls, the
According to the manufacturer, the torpedo reaches a speed of over 400 km/h underwater and is steerable.[1] It is not dependent on the launch from submarines but can dive into the water from the air and continue its supercavitation trip from there.
