“Russian port operator Rosmorport recently took delivery of Viktor Chernomyrdin, the largest diesel-electric icebreaker ever built by a Russian shipyard….Viktor Chernomyrdin boasts a length of 146.8 metres, a moulded beam of 29 metres, a minimum draught of 8.5 metres, a maximum draught of 9.7 metres, and a displacement of approximately 19,070 tonnes. Because the vessel’s draught is variable, it can sail in inland waterways and other shallow areas aside form its primary area of operations that encompasses the Baltic Sea and the Gulf of Finland.”
This ship is slightly larger than the planned Polar Security Cutter, but is apparently less powerful (33,600 HP compared to 45,200 for the PSC). Using the Coast Guard classification, she is a medium icebreaker. But unlike many other Russian Icebreakers, this one seems to be capable of transiting to Antarctica if required.
