Flight trials of the Yantar-2K indicated the satellite was not capable of providing strategic warning of attack. The planned Yantar-6K series, in development since 1969, were overweight and behind schedule. A meeting of the Council of Chief Designers at TsSKB reviewed alternative approaches. It was decided that three variants of the Yantar-2K were to be developed, one of them the high resolution Yantar-4K.
