Bditel'nyy or Bditelnyy (Russian: Бдительный, "Vigilant") was a Project 1135 Burevestnik (Russian: Буревестник, "Petrel") Large Anti-Submarine Ship (Большой Противолодочный Корабль, BPK) or Krivak-class frigate that served with the Soviet and Russian Navies. Launched on 28 March 1970, the vessel served as part of the Baltic Fleet but operated more widely than the Baltic Sea, demonstrating the emerging blue water capability of the Navy. A dedicated anti-submarine vessel, with an armament built around the Metel system, the ship spent the period between 26 December 1970 and 30 September 1971 undertaking trials and tests to prove the new systems. During that time General Secretary Leonid Brezhnev and Admiral of the Fleet Sergey Gorshkov were both hosted on board. The vessel then subsequently undertook tracking of submarines in the Baltic, Black and Mediterranean Seas, and even travelled as far as Cuba, crossing the Atlantic Ocean. The ship also visited friendly ports like Annaba in Algeria, Gdynia in Poland and Rostock in East Germany. With the end of the Cold War, the ship also travelled to Belgium and visited Antwerp. During June 1993, Bditelnyy took part in BALTOPS-93, the first joint exercise between NATO and Russia. However, soon afterwards, the ship was retired and, on 31 July 1996, decommissioned and subsequently broken up.
