The P-70 Ametist ( GRAY index 4K66 , NATO reporting name SS-N-7 Starbright ) was a submarine -assisted anti-ship missile manufactured in Russia. It was the world's first anti-ship guided missile that could be used by submerged submarines.
development
The P-70 was used to combat naval forces and aircraft carrier groups. The development in the design office NPO Maschinostrojenija Tschelomei began in 1959. The first systems were introduced in 1968 in the Soviet naval forces. The following classes of submarines were equipped with the P-70:
- Charlie I class with eight guided missiles each
- Papa class with ten guided weapons each
technology
The guided weapons were housed in launch and transport containers outside the pressure hull. Before the start, the coordinates and the course of the target had to be entered in the navigation system of the missile . These were determined from the submarine using sonar or ELINT . The guided missile launch could only take place from the submerged submarine. The launch of the missiles was done with the help of the marching engine and four boosters on the rear of the missile. The guided missiles could be launched individually or in series from a maximum depth of 30 m. After piercing the surface of the water, the guided missile rose to a height of around 100 m. After the four boosters had burned out, they were thrown off and the guided missile sank to a cruising altitude of 30 to 60 m. A radar altimeter provided the necessary safety distance between the missile and the sea surface. The P-70 was a fire-and-forget guided weapon and the flight to the target area was carried out autonomously with the help of the inertial navigation platform . The on-board radar seeker was activated for the target approach . Once the target was captured, it was approached in a low dive. The impact in the target took place at water level.
distribution
The P-70 was only used by the Soviet naval forces. The system was never exported.
