In June 2002, now serving in the Russian Navy, TK-208 finally left the Severodvinsk dry dock. After 12 years of overhaul and modifications, it had now received the name "Dmitriy Donskoy", named after the Grand Duke of Moscow Dmitry Donskoy (1359–1389), the reputed founder of Moscow. The twenty launchers for the R-39 missiles it originally carried were replaced with launchers for the most advanced submarine-launched ballistic missile to date, the RSM-56 Bulava. Although it was built as a third generation submarine, the vessel is now referred to as a fourth-generation submarine due to its extensive modifications.
