История загоризонтной радиолокационной системы «Дуга» (Dubrovskiy & Kostuchenko, 2012)

Independent academic chronology of the Duga system (Privolzhsky Scientific Herald, 2012): Kabanov’s 1946-47 proposal, the 1949 Veyer program, the mid-1960s Nikolaev construction, the first experimental detection of a launch on 7 November 1971, the 1975 Komsomolsk-on-Amur node, the 1985 acceptance of Chernobyl-2, the April 1986 disaster that disabled the western node, and the 14 November 1989 decommissioning of the eastern one. Useful precisely because it does not depend on Babakin for its dates. Full PDF via CyberLeninka.
