A naval base is a facility that supports naval operations and serves as a home for naval ships and submarines. These bases provide essential services such as maintenance, logistics, and training for naval personnel. They are strategically located near coastlines to allow for easy access to the open sea and to enhance national security. Naval bases often include docks, repair facilities, and living quarters for sailors. They may also house various military equipment and technology, including aircraft and weapons systems. Examples of prominent naval bases include Naval Station Norfolk in the United States and HMNB Portsmouth in the United Kingdom.
