These conditions have increased enormously the cost of submarine and sailors started to call it by nickname "Golden Fish". However in result it was a unique submarine, which has no equivalent elsewhere. In 1969 K-162 was ready. During the trial trip at 80% power, reactors developed speed 42 knots. In 1971 at full power it produced steady speed of 44.7 knots (87.8 km / h), which is record for submarines.
