Soviet-built patrol boats armed with "Osa-M" anti-aircraft missile system. The development of the complex was carried out with 1960 city, tests were conducted in 1967 city, he was adopted by the Soviet Navy in 1971 g. The complex consists of surface-to-air missile 9MZZ (NATO code in the system has the designation SA-N-4), launcher ZIF-122, 4F-management system 33 and storage device, feeding and loading missiles.

The complex is unified with the Army 9KZZ SAM "Wasp" missile on 100% and management systems - to 70%.
Antiaircraft 9MZZ solid-driven rocket made of aerodynamic configuration "duck". The weight of the rocket - 128 kg (the weight of the warhead - 15 kg), length - 3158 mm, the largest diameter of the body - 206 mm, wingspan - 650 mm. Management rocket in flight by two pairs of rudders on the radio commands from the control system. In the nose of the rocket are located radio equipment and radiovizirovaniya, autopilot, fuze, onboard power supply and a warhead with slam-actuator. In the tail parts are dual-mode solid-propellant motor, command and the radio antenna onboard transponder, as well as tracers for tracking missiles with the help of television-optical sight.
A feature of the control system and its antenna post is, that they contain not only the missile guidance radar, but also small circular scan radar for target detection in the near field. Thanks to this SAM does not require targeting of the total detection radar, although such a possibility is not excluded. In this way, due to the alignment target detection and tracking for capturing modes in one system could shorten the time for the complex reactions 6-8 seconds.
Complex "OSA-M" is equipped with two-beam suggestive launcher ZIF-122 with storage device, feeding and loading, calculated on 20 missiles. The design of the launcher is quite unusual and is not repeated in any other anti-aircraft missiles.
