Located near Jacksonville on Florida’s Atlantic coast, Naval Station Mayport is one of the United States Navy’s most important military installations. The base sits at the mouth of the St Johns River and provides direct access to the Atlantic Ocean for Navy ships and aircraft.

The installation serves as both a naval air facility and a deep-water port for warships. It supports a wide range of military operations including fleet deployments, maritime security missions, training exercises, naval aviation activity and logistical support.

Naval Station Mayport is home to several guided missile destroyers and helicopter squadrons and is considered a key fleet concentration area on the East Coast. The base also plays an important role in Atlantic and Caribbean operations, NATO exercises and humanitarian response efforts.
