Analysis of information sources in references of the Wikipedia article "Vladimir Chelomey" in English language version.
He was still in good health when he suffered a bizarre accident at his dacha in December 1984.
On 12 October 1964, only two days before the overthrow of Khrushchev, Chelomei obtained permission to begin development of a larger crewed military space station, the Almaz. This 20 tonne station would take three cosmonauts to orbit in a single launch of his uprated UR-500K Proton rocket. Therefore there were now two competing projects for the same mission - Almaz and Soyuz-R.
