AKA: 11F622. Status: Study 1968.
The DS satellites of KB Yuzhnoye (Chief Constructor V M Kovtunenko) were used to solve problems related to the planned Yantar series. But Yuzhnoye was too busy building ICBM's for the RSVN (Soviet Rocket Forces). So Kozlov's Filial 1 of OKB-1 took up the project after a delay in 1967 to 1969. Succeeded by Kozlov's very different Yantar-2K.
Early Yantar design by KB Yuzhnoye.
