About Sever

Soyuz Sever, also spelled Soyuz Siber,, was an early (1959–1962) design of the Soyuz spacecraft. The Soyuz Sever design of a crewed spacecraft started the Soyuz programme. In 1956, the Soyuz Sever spacecraft was proposed as the replacement for the Vostok spacecraft. Vostok spacecraft had only a crew of one; the Soyuz Sever plan would have crew of three. Sever was planned to be launched on a R7 rocket or Vostok rocket. The Sever plans were made by the Experimental Design Bureau (OKB-1) of the Soviet Union. While the Sever spacecraft was never built and launched, many of the designs and testing outcomes became part of the first generation Soyuz spacecraft, Soyuz 7K-OK and the Soyuz 1 mission launched on 23 April 1967. Sever final plan was to take crews to a Sever space station, OS-1962.
