Attack submarines are military vessels designed to engage enemy ships and submarines. They are equipped with advanced sonar systems and torpedoes, allowing them to detect and target threats underwater. These submarines can operate stealthily, making them difficult to detect by enemy forces. Typically powered by nuclear energy, attack submarines can remain submerged for extended periods, enhancing their operational capabilities. They play a crucial role in naval warfare, gathering intelligence and providing support to other military operations. Their versatility allows them to perform various missions, including surveillance and reconnaissance.
