The radar Flag was a surveillance radar operating in the X-Band for use on submarines. The radar was intended to detect surface targets, determine their target coordinates, and ensure torpedo launch by the submarine on enemy vessels. It could also be used for navigation and operated both on the surface and underwater at periscope depth.
The antenna was protected against high water pressure and could operate in 360-degree rotating or sector mode. The target display was on two PPI scopes.
The Flag radar station was developed between 1946 and 1948 and was included in the Soviet Navy's armament on June 14, 1950.
