North Island Naval Air Station-Halsey Field — San Diego, United States

NZY is the code for Naval Air Station North Island's Halsey Field, located in Coronado, San Diego, California, a major installation of the United States Navy. NAS North Island is home to Naval Air Force Pacific and serves as a hub for aircraft carrier air wings, naval aviation training, and maintenance operations, and is historically significant as one of the birthplaces of American naval aviation in the early 20th century. NZY supports fixed-wing and rotary aircraft operations tied to Pacific Fleet carrier deployments. As an active military base, NZY is not accessible for civilian commercial travel; it functions strictly as defense infrastructure supporting United States Navy operations along the Pacific coast.
