Submarine operations involve the use of submarines for various military and research purposes. These operations can include surveillance, reconnaissance, and strategic deterrence. Submarines are designed to operate underwater, allowing them to remain hidden from enemy detection while gathering intelligence or launching attacks. In addition to military functions, submarines are also used for scientific research, such as studying marine life and underwater geology. They can carry specialized equipment for deep-sea exploration and data collection. The versatility of submarines makes them valuable assets in both defense and scientific communities, contributing to national security and environmental understanding.
