Anti-Submarine
RBW-37
The RBW-37 is a 350 mm calibre anti-submarine and anti-torpedo rocket launcher which entered service around 1955. The RBW-37 is remotely aimed by the fire control system.
The launcher consists out of two, four or six barrels depending on the ship. Automatic reloading from the magazine takes less than two minutes.

RBW-22
The RBW-22 is a 220 mm calibre anti-submarine and anti-torpedo rocket launcher. It entered service around 1992 and is remotely aimed by the fire control system.
The launcher consists of twelve barrels which are automatically loaded one at a time from a below deck magazine that holds 96 rounds per launcher. It fires RWG-22 unguided depth charges. The rockets are normally fired in salvos of 1, 2, 4, 8 or 12 rounds. Reloading is automatic, with individual rounds being fed into the launcher by the 60UP loading system from a below deck magazine. It can also be used as a shore bombardment system.
The RPK-8 system is an upgrade of the RBW-22 system, firing the 90R rocket, which is actively guided in the water. This allows it to home in on targets at depths of up to 1,000 meters. The warhead is a 19,5 kg shaped charge, which enables it to punch through the hulls of submarines. It can also be used against divers and torpedoes. System response time is reported to be 15 seconds and a single-salvo has a kill probability of 0.8.

UAW-2
The weapon is essentially a missile-delivered version of the AST-62 torpedo. The launcher is a circular mount which allows the weapon to be slewed to the correct bearing, whereupon it is fired at the target's location. A solid booster rocket accelerates it to 830 km/h within 4 seconds. The unpowered missile continues at an altitude of 100 meters, altering course in mid-flight under radio control of the launch platform. As it reaches the target the glider drops the torpedo which deploys a parachute and then splashes into the sea and commences a circular search pattern.
