The Kirov class battle cruiser, the largest and most powerful surface warship currently in service (excluding aircraft carriers), first entered service in 1980. A total of four have been built since that time, and only one (The Pyotr Veliky, ie, Peter The Great) remains in service as the flagship of the Northern fleet. The introduction of this battle cruiser in the 1980’s was one of the reasons the US Navy chose to recommission the Iowa Class battleships.
The Peter The Great’s main armament is composed of twenty P-700 Granit supersonic anti-ship missiles, which have a range of 550-625 km. Air defense is provided by 9K311 Tor short range surface-to-air missiles and 96 S-300F long range surface-to-air missiles. The Peter The Great is also armed with a single AK-130 130 mm main gun, eight AK-630 30 mm Gatling guns, and six Kashtan gun/missile systems. For ASW (anti-submarine warfare), the ship is armed with the RBU-1000 ASW rocket launcher, ten 533 mm torpedo tubes (which can fire either the Type 53 torpedoes or the RPK-2 ASW missiles, and up 3 Ka-27 helicopters.
The Peter The Great has a displacement of over 28,000 tons (when fully loaded), a length of 252 meters, a beam of 28.5 meters, and a draft of 9.1 meters. The ship has a speed of 32 knots and has a crew of 710. The Peter The Great is powered by nuclear and steam turbine propulsion.
