The SS-N-9 Siren is a ship- and submarine -assisted anti-ship missile from the Soviet / Russian production. The GRAU index is 4K85 and the system index of the Russian armed forces is P-120 malachite .
development
The SS-N-9 was developed as the successor system to the SS-N-7 Starbright . The system is used to combat naval war groups and aircraft carrier groups. The development in the design office OKB-52 Tschelomei (later NPO Maschinostrojenija ) began in 1963. The first systems were introduced in 1972 with the Soviet naval forces. The following units were equipped with the SS-N-9:
- Submarines of the Charlie-II class with eight missiles
- Corvettes of Nanuchka class with six missiles
- Hydrofoils of Sarancha class with four missiles
variants
- P-50 malachite: pre-production version. Range 70 km.
- P-120 Malachite: Standard version, range 110 km. Introduced in 1972
- P-120E Malachit-E: Export version with simplified electronics.
- P-120M Malachit-M: Improved version from 1975. With new electronics and new radar search head. Range 120–150 km.
technology
The guided missiles are housed in launch and transport containers outside the pressure hull. Before starting, the coordinates and course of the target must be entered in the missile's navigation system . These are determined from the submarine using sonar , radar or ELINT . The guided missiles are started with the help of the marching engine and two boosters on the rear of the missile. The guided missiles can be launched individually or in short series from a diving depth of up to 50 m. After piercing the surface of the water, the guided weapon rises to a height of around 100 m. After the two boosters have burned out, they are thrown off and the guided missile sinks to a cruising altitude of 40 m. A radar altimeter ensures the necessary safety distance between the missile and the sea surface. The flight to the target area takes place autonomously with the help of the inertial navigation platform . Updated target data can be sent from the launch platform to the missile using a data link . An active radar seeker head and a passive infrared seeker head are used for approaching the target . Once the target has been captured, it is approached in a low dive. The impact in the target takes place at water level.
distribution
The SS-N-9 is only used by the Russian naval forces. The system was never exported.
