Berkut spacesuit
The Berkut is a space suit model developed to be used for extravehicular activity for the Voskhod 2 mission aboard a Voskhod spacecraft on the first spacewalk. It was developed by NPP Zvezda in 1964–1965. It was a modified SK-1 suit. It was only used by the Voskhod 2 crew.Specifications
The suit had two pressurization settings, one at 0.27 atmospheres and the other at 0.40 atmospheres. Life support was contained in a back pack, which had a large enough oxygen supply to last for 45 minutes of activity. Movement within the suit was seriously restricted.
