B-585 Sankt Peterburg (Russian: Б-585 «Санкт-Петербург»; named after Saint Petersburg) is the lead boat of the Lada-class submarines of the Russian Navy. The Lada class is the fourth generation of diesel-electric submarines designed and constructed in the former Soviet Union and Russia to replace the Kilo class. Construction of the boat started in December 1997, and she was launched in October 2004. After undergoing a series of sea trials, Sankt Peterburg was commissioned in May 2010. However, the Russian Navy decided not to accept the St. Petersburg class after it was discovered that the boat's propulsion and sonar systems were inadequate. After design corrections the submarine was accepted. In 2014, Sankt Peterburg joined the Northern Fleet. In 2023, it was reported that due to the extremely high costs of modernising the submarine, the Sankt Peterburg was to be decommissioned and scrapped, with the funds being diverted to new submarine construction.^[5]
