Saint Dmitry Ivanovich Donskoy (Russian: Дми́трий Ива́нович Донско́й,also known as Dimitrii or Demetrius), or Dmitry of the Don, sometimes referred to simply as Dmitry (12 October 1350 in Moscow – 19 May 1389 in Moscow), son of Ivan II the Meek of Moscow (1326–1359), reigned as the Prince of Moscow from 1359 and Grand Prince of Vladimir from 1363 to his death. He was the first prince of Moscow to openly challenge Mongol authority in Russia. His nickname, Donskoy (i.e., "of the Don"), alludes to his great victory against the Tatars in the Battle of Kulikovo (1380) which took place on the Don River. He is venerated as a Saint in the Orthodox Church with his feast day on 19 May.
Dmitry ascended the throne of the Principality of Moscow at the age of 9. During his minority, Russia's Metropolitan Aleksey ran the government. In 1360 Khizr-khan , Khan of the Golden Horde, transferred the title most prized among Russian princes, that of Grand Prince of Vladimir, to Dmitry Konstantinovich of Nizhniy Novgorod. In 1363, after that prince was deposed, Dmitry Ivanovich was crowned at Vladimir. Three years later, he made peace with Dmitriy Konstantinovich and married his daughter Eudoxia. In 1376 their joint armies ravaged Volga Bulgaria.
Dmitri Donskoy (TK-208) is a Russian Navy nuclear ballistic missile submarine, designated Project 941 Akula class (NATO reporting name Typhoon). It is the largest nuclear submarine in the world.
Hull number TK-208 was the lead vessel of the Soviet third generation Project 941 Akula class (NATO reporting name Typhoon) of ballistic missile submarines. She was laid down at the Severodvinsk shipyards on 3 March 1977 and launched on 22 September 1980. At 175 metres in length, she became the world's largest submarine, a record which she still holds along with her five sister ships.
In 1990, she entered the dry dock in Severodvinsk for upgrades and repairs. Due to both economic and technological problems, the completion was severely postponed. In 2000, work on the submarine was intensified.
In June 2002, now serving in the Russian Navy, TK-208 finally left the Severodvinsk dry dock. After 12 years of overhaul and modifications, she had now received the name Dmitry Donskoy, named after the Grand Duke of Moscow Dmitry Donskoy (1359–1389). The twenty launchers for the R-39 missiles she originally carried were replaced with launchers for the most advanced submarine-launched ballistic missile to date, the RSM-56 Bulava. Although she was built as a third generation submarine, the vessel is now referred to as a fourth generation submarine due to her extensive modifications.
At least three ships of the Imperial Russian, Soviet or Russian Navy have been named Dmitri Donskoi after Dmitry Donskoy.
