The blaze started on the Admiral Kuznetsov, Russia's only aircraft carrier, while it was docked at the Zvyozdochka shipyard in the Barents Sea port city of Murmansk, located in the far north-west of Russia, news agency Tass said.Alexei Rakhmanov, head of the United Shipbuilding Corporation (USC), which is overseeing renovation of the vessel, told RIA Novosti that the incident occurred during repair work.In November Rakhmanov told reporters in Moscow that "obstructions" were found in separate sections of the ship but "the work is on schedule," and that "we will do everything to make this happen."In March 2021 the director general of the shipyard overseeing the repairs was arrested for embezzlement of funds totaling 45 million rubles ($606,300), Tass reported.Russia's war effort in Ukraine was dealt a major blow after the Black Sea fleet flagship Moskva sank in April after it was attacked by Ukrainian forces."
