There is officially no Air Force of Costa Rica; the only air wing in existence is attached to the Public Force of Costa Rica. Currently this unit, officially called Air Vigilance Service ( (SVA)), also called the Air Service (Servicio Aéreo), does not operate any armed military aircraft. Its main air bases located in three different points, San José (Base 2) being the main operations center. Mission and Functions The SVA's mission is to: "Provide air support in security actions carried out by police forces, in humanitarian missions, transfers of government officials; Provide security and surveillance in the country's airports to protect domestic and foreign citizens." Some of the most common functions of the SVA are transporting civilians in critical medical emergencies to the hospitals in the capital as well as helping in the war on drugs. Plenty of drug trafficking operations are carried in joint agreement with the U.S., mainly occurring in the coastal areas and at sea.

History Costa Rica is one of the oldest democracies in the region and formally abolished its army on December 1, 1949, just after the end of a revolution that reformed the country's political structures. The internal security of the country was administered by the Civil Guard that, over the years, has transformed into what it is now, the Public Forces of Costa Rica, under the command of the Ministry of Public Security. It is composed of several departments: Public Force, Anti-Drug Police, National Coast Guard Service, National Police School, Reserve of the Public Force and the Air Surveillance Service, itself a successor of the Costa Rican Air Force. In 1958, the air wing was created with a Cessna 180 for the transportation of government officials and in 1962 it acquired three Cessna 185s. Later in 1970, it acquired a helicopter for use by the President. In 1994, it was renamed the Air Vigilance Service (Spanish: Servicio de Vigilancia Aérea, SVA), with 15 aircraft.
