Last year, on the 30th of October 2018, the Admiral Kuznetsov was damaged when Russia’s biggest floating dry dock, the PD-50, sank and one of the dock’s 70 ont cranes crashed onto the ship’s flight deck leaving behind a 200 square foot hole in the flight deck.

One person was reported missing and four injured as the dry dock sank in Kola Bay. Admiral Kuznetsov was in the process of being removed from the dock when the accident happened, and was towed to a nearby yard after the accident.

More on this as it develops.
