基洛夫級飛彈巡洋艦（英語：Kirov class battlecruiser，俄語：Крейсера проекта 1144 «Орлан»「海鷹」），是俄羅斯乃至全世界僅次於航空母艦的最大型軍艦，也是目前全球唯一排水量超過兩萬噸及使用核子動力的現役巡洋艦。艦上裝載超過400枚飛彈，因此有「武庫艦」的稱號。
基洛夫級大約有1600個船艙。其中140個單人或雙人間的軍官和士官住艙，30個軍士和水兵住艙。全艦有220個門廊，49條走廊，總長度近20公里。艦上設有15間淋浴室，兩間浴室，一間桑拿浴室，以及一座小型游泳池，另外還設有圖書室和健身娛樂中心，雙層的醫療中心，包括門診部，藥房，X光室，手術室，看護隔離病房和牙科診所。
該級艦擁有完善電子設備和驚人的火力。巨大的雷達組件安裝在前桅杆，北約稱為「頂對」（Top Pair）。
主武器是20枚P-700花崗岩反艦飛彈，可以擊沉大型水面艦。據說，該型VLS具備在20秒內2枚飛彈齊射的能力。
防空方面有12座8聯裝迴轉式S-300F堡壘/SA-N-6雷鳴防空飛彈共96枚[1]（四號艦換成了更先進的S-300FM堡壘-M/SA-N-20石像鬼飛彈）。配合艦橋頂部的「頂板」AESA雷達，可以攔截彈道飛彈和高空高速轟炸機。還有2座20聯裝VLS，裝載9K33M黃蜂-M/SA-N-4壁虎飛彈共40枚。
The Kirov-class battlecruiser is a class of nuclear-powered warship of the Russian Navy, the largest and heaviest surface combatant warships (i.e. not an aircraft carrier or amphibious assault ship) currently in active operation in the world. Among modern warships, they are second in size only to large aircraft carriers, and of similar size to a World War I-era battleship. The official designation of the ship-type is "heavy nuclear-powered guided missile cruiser" (Russian: тяжёлый атомный ракетный крейсер), but because of their size and general appearance, the ships are often referred to as battlecruisers by western defense commentators.
Originally built for the Soviet Navy, the class is named for the first of a series of 4 ships to be constructed, Kirov, which was renamed Admiral Ushakov in 1992. Original plans called for the construction of 5 ships, however the last was cancelled. In Russia this class of ship is usually referred to by the designation Project 1144 Orlan (sea eagle). Only the Pyotr Velikiy is still operational. Russia planned to reactivate the remaining three vessels by 2020 but recent reporting suggests that the reactors in Ushakov and Lazarev are in a poor condition, and these ships cannot be safely reactivated
The Russian heavy missile cruise ship, Project 1144.2 Kirov Class was built by the Baltic Shipyard in Saint Petersburg. The Kirov Class provides the capability to engage large surface ships and to defend the fleet against air and submarine attack. Four cruisers were built but only Admiral Nakhimov (commissioned in 1988) and Pyotr Velikhiy (commissioned in 1995) remain active.
Missiles
The ship is armed with the Granit (Nato designation SS-N-19 Shipwreck) long-range anti-ship missile system. 20 Granit missiles are installed under the upper deck, mounted at a 60° elevation. The version of Granit on the Kirov is not controlled after launch. In ripple-fire mode, the lead missile follows a high flight trajectory, while the other missiles follow a low-level flight path. If the lead missile is intercepted then one of the other missiles automatically takes on the lead role.
