The yard is located in the Rosta district in the northern part of Murmansk and the quay where «Admiral Kuznetsov» is at port is next to Atomflot, the service base for Russia’s fleet of nuclear powered icebreakers.

«Admiral Kuznetsov» is Russia’s only aircraft carrier. The vessel has been under modernization since 2018, a work that is said to last until 2022.

Last fall, a huge floating dry-dock holding the carrier sank at yard No. 82 in Roslyakovo north of Murmansk. The deck of «Admiral Kuznetsov» was then damaged as a crane fall over.

The carrier has a bad record accidents.

In November 2014, a MiG-29 fighter jet crashed while trying to land on the aircraft carrier during a mission in the Mediterranean off the Syrian coast. Also in 2005, a Su-33 aircraft went off deck during landing and sank.

«Admiral Kuznetsov» was commissioned in 1991. The 305 meters long vessel is the largest in the Russian navy and has all time been deployed with the Northern Fleet.
