Russia’s Project 667BDR nuclear-powered ballistic missile submarine ‘Ryazan’ returned to service after it spent five years in the docks undergoing repairs and modernization.
Russia’s Ministry of Defence confirmed that the submarine returned to its homeport in Vilyuchinsk, Kamchatka after completing repairs at the shipyard Zvezda.
Ryazan, one of three remaining Project 667BDR submarines, has been undergoing repairs since 2011.
The submarine was laid down in January 1980 and commissioned into the Russian Northern Fleet in September 1982. After undergoing in 2007, Ryazan changed her homeport and became part of Russia’s Pacific Fleet in 2008.
The 155-meter-long submarine has an operating depth of 400 metres and is crewed by 130 servicemen. It carries four 533-mm and two 400-mm bow torpedo tubes. Delta III submarines are equipped with 16 submarine-launched R-29R ballistic missiles.
