How many destroyers typically displace between 8300 to 9000 tons?

The correct answer is destroyers, as they are a class of warship typically designed for high-speed combat and capable of operating in a wide range of naval warfare scenarios. Often classified by their displacement, destroyers usually fall within the range of 8,300 to 9,000 tons due to their advanced technologies and weapon systems, which often include guided missiles, torpedoes, and various sensors. This displacement allows them to accommodate the necessary equipment for anti-air, anti-surface, and anti-submarine roles, aiding in multi-dimensional warfare tactics.

In contrast, frigates are generally smaller and have a lower displacement, focusing on escort duties and protection of larger vessels. Corvettes are even smaller and typically used for coastal defense and patrol duties. Submarines, while also a critical component of naval power, have entirely different designs and roles that do not align with the criteria specified in the question regarding displacement.
