North Island Coronado – North Island Coronado – Naval Air Station North Island and Naval Base Coronado are both located on Coronado Island, CA, and fall under the same Commanding Officer. Officially recognized as the "Birthplace of Naval Aviation", the Navy's first aviator was trained on the Island around 1911. Coronado is Spanish for "the crowned one", thus our charm is a .925 sterling silver crown accented with clear gems. Inscribed along the rim is "NB Coronado CA".
