Russia's only aircraft carrier damaged after crane falls on it

Russia’s only aircraft carrier was damaged while undergoing repairs in the north of the country after the floating dock holding it sank in the early hours of Tuesday and a crane crashed onto its deck, tearing a gash up to 5 meters wide. The non-nuclear Admiral Kuznetsov is powered by eight turbo-pressurized boilers, four steam turbines, and six diesel generators, bringing the carrier to a maximum speed of about 33 mph.

The Admiral Kuznetsov, is one of the five worst carriers in the world, according to The National Interest.

It was being overhauled on one of the world’s biggest floating docks in the icy waters of the Kola Bay near Murmansk close to where Russia’s Northern Fleet is based and was due to go back into service in 2021.

Maria Kovtun, Murmansk’s governor, said in a statement that a rescue operation had been launched and 71 people evacuated after the floating dock holding the ship had begun to sink.

They require forced water circulation. The US Navy had several classes of vessels with a similar boiler (link below). The ships could accelerate like crazy though.

Even if they raised it, I would assume a major overhaul would be needed.
