Coast Guard Air Station Borinquen is located at Rafael Hernandez Airport on the Northwest tip of Puerto Rico. The closest city is Aguadilla, just 10 minutes to the South. The Air Station moved to this location from San Juan in the fall of 1971, at which time the Coast Guard took possession of an outstanding hangar with adjacent support facilities.
The responsibility for the station complex, formerly part of Ramey Air Force Base and later Naval Station Roosevelt Roads West Annex, was assumed by the Coast Guard on 1 July 1976. Included in the boundaries of the base are the housing area, clinic and dispensary, station library, community center, swimming pool, exchange, mini-mart, package store, gymnasium, and other fitness facilities, chapel, and theater.
The primary mission of Coast Guard Air Station Borinquen is search and rescue. Secondary missions include law enforcement, aerial support for aids to navigation, and logistics support. The Air Station is assigned four MH-65 helicopters to complete all mission sets, and routinely supports deployed aircraft from around the Coast Guard. The Air Station is a partner unit of and receives mission coordination from, Coast Guard Sector San Juan (old GANTSEC), located in Old San Juan. The area of responsibility extends approximately 1.3 million square miles.
