Submarine squadrons are groups of submarines organized for operational efficiency and tactical coordination within a navy. Each squadron typically consists of several submarines, which may be of different classes, and is responsible for specific missions, such as surveillance, reconnaissance, or strategic deterrence. These squadrons are often part of larger naval fleets and work closely with other naval assets, including surface ships and aircraft. The organization allows for better resource management and training, ensuring that submarines can effectively carry out their roles in national defense and maritime security, often under the command of a senior officer.
