Submarine operations involve the use of submarines to conduct various military and research activities underwater. These operations can include surveillance, reconnaissance, and strategic deterrence. Submarines are equipped with advanced technology to navigate and communicate while remaining hidden beneath the surface of the water. In military contexts, submarines can launch torpedoes and missiles to engage enemy vessels or targets. They also play a crucial role in gathering intelligence and monitoring maritime activities. Additionally, submarines are used for scientific research, exploring ocean depths and studying marine life, contributing to our understanding of underwater ecosystems.
