The Russian multipurpose nuclear submarine of the 4th generation K-561 "Kazan" (the second in the series of project 885M "Yasen-M") received its name from the legendary Soviet 2nd generation submarine K-403 "Kazan" (project 667A "Navaga"), the conning tower of which became a military-historical memorial in the Victory Park of the city of Kazan.
The strategic missile submarine K-403 was built in 1971 at the Sevmash plant according to the project of the Rubin Design Bureau. "Kazan" was part of the Northern Fleet and was assigned to the port of Gadzhiyevo in the Murmansk region.
