Top 10 best submarine in the world
A submarine is a specialized vessel capable of underwater operation. It features a strong, watertight hull to withstand deep-sea pressure and uses ballast tanks to control buoyancy, allowing it to dive and surface. Propelled by diesel engines, nuclear reactors, or other systems, submarines can remain submerged for varying lengths of time. Equipped with advanced sonar for detecting obstacles and other vessels, and often armed with torpedoes and missiles, submarines play crucial roles in military operations, including strategic deterrence and reconnaissance. They also contribute to scientific research and deep-sea exploration.
