The Berkut (Russian Беркут, meaning golden eagle) 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.
