Soviet K-3 submarine corresponding to Project 627 or known in NATO code as November class in an image of 2015. It remained inactive from its discharge in 1988 until 2006 when it was decided to reconvert it into a museum ship after removing it the nuclear reactor.
Apparently in 2017 he was still in restoration phase with no knowledge of his current status. It was the first Soviet nuclear submarine put into service in 1958 and the first Soviet submarine to emerge at the North Pole in 1962
