The cruiser is a large surface ship with strong firepower and multiple purposes, mainly for ocean-going activities. The cruiser is equipped with strong offensive and defensive weapons, has a high speed and seaworthiness, and can conduct long-term ocean operations in harsh weather conditions.
The main task of the cruiser is to escort aircraft carriers and battleships, or as the flagship of the formation to form a maritime mobile formation to attack enemy surface ships, submarines, or targets on the shore.
With the development of the times, cruisers have gradually declined. After World War II, countries have basically no longer built cruisers. Only the United States and the Soviet Union have built several levels, such as the Ticonderoga class in the United States and the Kirov class in the Soviet Union. . After entering the 21st century, cruisers will gradually be replaced by destroyers, which will become history.
