On the anti-ship capability, eight modern Japanese-made missiles have a range of more than 200 kilometers and are known as "aircraft carrier killers". It is also reported that an average of 1.2 can sink a destroyer, which is more powerful than almost any ship-borne anti-ship missile in active service.
However, the range of more than 200 kilometers means that the missile needs the navigation of carriers such as helicopters, which requires the air superiority of the battlefield. However, two modern 9K90 single-arm ship-to-air missile launchers (48 bombs) are obviously not enough, and they need the cooperation of Chinese Aegis-class air defense destroyers or aircraft carriers and fighters. In addition, the modern anti-submarine capability is obviously insufficient, and an anti-submarine helicopter is not enough to cope with the wall climbing in the theater. Soviet standards are modern anti-ship and fearless anti-submarine.
In short, modern warfare has become three-dimensional, and considering more complicated contents such as electronic warfare, no warship can be said to be the "strongest". So is the modern level. However, on the idealized level, considering the combat capability of anti-ship missiles, the eight modern Japanese missiles are indeed the most powerful in the world.
