Surveillance vessels are specialized ships designed to monitor and gather information about maritime activities. They are equipped with advanced technology, such as radar, sonar, and cameras, to track ships, detect illegal fishing, and ensure maritime security. These vessels play a crucial role in protecting national waters and enforcing laws at sea. These ships are often used by government agencies, such as the Coast Guard or navy, to patrol large ocean areas. Surveillance vessels can also assist in scientific research by collecting data on marine life and environmental conditions, contributing to better understanding and management of ocean resources.
