A fleet submarine is a type of military submarine designed primarily for operations in support of naval fleets. These submarines are equipped for various missions, including anti-submarine warfare, reconnaissance, and strike operations. They are typically smaller and more agile than strategic submarines, allowing them to operate closer to enemy forces and provide tactical advantages. Fleet submarines are often armed with torpedoes and cruise missiles, enabling them to engage surface ships and other submarines effectively. They play a crucial role in maintaining maritime security and can be deployed for both offensive and defensive operations, contributing to the overall effectiveness of a nation's naval capabilities.
