Lists on the subject

The SS-N-14 Silex is a ship-based anti -submarine guided weapon and anti-ship guided weapon made in Russia. The system name is UPRK-3 Metel / UPRK-4 Musson ( Metel means snow storm, Musson means monsoon).

development

The development of the SS-N-14 system began in the 1950s. The development takes place in the design office Raduga and in OKB-52 Tschelomei . After lengthy tests, the system was finally introduced to the Soviet Navy in 1968. In the following years the following classes of ships were equipped with the SS-N-14 system:

technology

The guided weapons are housed in large steel containers on the ship's deck and are fired directly from them. When starting, a rocket booster pushes the missile out of the launch tube. Immediately after leaving the launch container, the wings unfold and the rocket motor ignites. The guided weapon flies into the target area at an altitude of 400 to 800 meters (m). Necessary course corrections are determined by the “Eye Bowl” or “Head Lights B” radars and transmitted to the missile via a radio link. Once in the target area, the guided missile drops a submarine chasing torpedo or a nuclear depth charge, depending on the version, on the assumed position of the submarine.

The SS-N-14 is primarily used to combat submarines. In a secondary role, ship targets can also be fought. When fighting a ship, the cruise flight takes place at a height of 50 m. For the final approach to the target, the missile sinks to an altitude of 15 m. A passive infrared seeker head is used for the target approach . The torpedo remains on the guided weapon until it hits the ship's hull and is detonated using an impact fuse.

status

The SS-N-14 system was never exported and is only used on ships of the Russian Navy. In use it has proven to be very costly and not very reliable. The currently only operational platforms are the last active cruiser of the Kara class , the destroyers of the Udaloy class and the frigates of the Kriwak class . In 2006, the Russian Navy still had 100 SS-N-14 guided missiles in stock. In use, the system was replaced by the much more straightforward SS-N-16 Stallion rocket torpedoes. The successor to the SS-N-14 is the RPK-9 Medwedka / 98R system ( NATO code name : SS-N-29 ). This system is much cheaper and more compact and can also be installed on small ships.
