VA-111 Shkval

Primary submarines, surface units possible

Shkval (Russian for squall Шквал, English transcription Shkval ) is the name of a developed in the Soviet Union torpedoes with reactive drive, which uses the super-cavitation to reduce the flow resistance. The official name of the Russian Navy is WA -111 Shkval.


Because of the secrecy in this sector are being made public for the technology and application area of ​​the Schkwal few precise information. The research on super-cavitation torpedoes at the Research Institute of Applied Hydromechanics began in the 1960s. These developed a prototype called M- fifth This had a rocket engine, which is used as a fuel hydrogen peroxide and kerosene. Based on the M -5 design was developed region of WA -111 Shkval later in the design office GNPO. The first test samples were delivered in 1977 to the Soviet Navy. The production version was introduced in 1992.


The Schkwal reached a speed of over 370 km / h It has a length of 8.2 meters and a weight of about 2700 kg. Before the main engine ignites, the Shkval is accelerated to sufficient for the generation of super-cavitation speed by eight annularly around the main engine Distributed small start engines. Gas discharge ports in the bow area to support the formation of the super-cavitation in addition. At the rear of the hull skids are unfolded after launch, which reach into the water beyond the cavern. They stabilize the torpedo like a tail. After starting the Shkval on the one hand, abspulenden wire to the launch site remains connected. Early versions were unguided, the newer models Schkwal -15 and Schkwal -15B have an actuator that can tilt the front of the cavitator in a plane. With only about an axis movable cavitator steering is possible in all directions because of the torpedo is rotated by the skids to rotate. A similar control principle is also used in some Russian air and anti-tank missiles used, is characteristic of the helical course of the trajectory.

A possible application of the Shkval torpedo is the defense against hostile submarines. Because submarines are Soviet-made until about 1980 as a relatively noisy, they were, for example, over comparatively quiet western hunting submarines at a disadvantage. Through the launch of Superkavitationstorpedos caused by their speed and enforcing defenses of the opposing submarine a time advantage. Another possible use variant of the Shkval is the destruction of aircraft carrier battle groups by means of a nuclear warhead.

The Shkval weapon system was offered after the end of the Eastern Bloc of the successor states of the Soviet Union ( CIS ) other countries to buy. Exports probably went to Iran and China.
