全球唯一排水量超過兩萬噸，僅次於航空母艦的最大型水面作戰軍艦，艦上裝載超過500枚飛彈，基洛夫級巡洋艦

基洛夫級飛彈巡洋艦（英語：Kirov class battlecruiser，俄語：Крейсера проекта 1144 «Орлан»「海鷹」），是俄羅斯海軍除航空母艦外最大型的水面作戰軍艦，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500枚飛彈，因此有「武庫艦」的稱號。
The Kirov class, Soviet designation Project 1144 Orlan (sea eagle), is a class of nuclear-powered guided missile cruisers of the Soviet Navy and Russian Navy, the largest and heaviest surface combatant warships (i.e. not an aircraft carrier or amphibious assault ship) in 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 ships are often referred to as battlecruisers by Western defence commentators due to their size and general appearance. The Soviet classification of the ship-type is "heavy nuclear-powered guided missile cruiser" (Russian: тяжёлый атомный ракетный крейсер).
