B-414 Daniil Moskovsky was a Project 671RTM Schuka (NATO: Victor III) attack submarine of the Russian Northern Fleet. The submarine was laid down in 1989, launched and commissioned in 1990. It was known as K-414 before renaming in 1992. In 1994 B-414 took part in joint combat service with SSBN Karelia (K-18) of the Delta IV class. In 1996 the submarine was named after Prince Daniil Moskovsky, the youngest son of Alexander Nevsky.

On 6 September 2006, a fire broke out on board killing two sailors.^[3]

On 18 November 2012, while reportedly engaged in routine "combat training" in the Barents Sea the submarine responded to a distress call and rescued two fisherman when their boat began sinking off the coast of the Kola Peninsula, reported to be somewhere between Liinakhamari and Teriberka. A spokesperson for the Russian Navy's Northern Fleet said the rescue was accomplished despite adverse weather conditions.^[4][5]

In 2019 it was reported that the Daniil Moskovsky would be retired by the end of 2021.^[6] However, the boat's status remained unclear as of January 2022. It was shown at dockside during a Combat Approved documentary in January 2022.^[7] The boat was reportedly decommissioned on 28 October 2022 and subsequently towed for scrapping.^[8]
