The "Kiev" aircraft carrier is an aircraft carrier and a cruiser. Its threat is equivalent to a special mixed fleet, which embodies the unique style of the Soviet aircraft carrier, so it is known as the "sea lion". Due to the disintegration of the Soviet Union, the domestic situation in Russia deteriorated, and the Russian navy was unable to bear the maintenance and use costs of Kiev-class aircraft carriers. 1994, the aircraft carrier Kiev was officially retired, and this Soviet-era "sea killer" once fell.
