Museo de la Aviación Naval, created 15 March 1990 by the Armada Argentina, preserves the history of Argentine naval aviation at the entrance to Base Aeronaval Comandante Espora near Bahía Blanca. Its collection includes aircraft, helicopters, engines, aviation equipment, armament and historic objects from the naval air arm established in 1916; guided visits and educational coordination are available. Public access is controlled by current Defense Ministry and municipal guidance: those listings differ on open days and note weather-related closures, so verify the current schedule and base-entry arrangements before travel. Detailed accessibility provisions are not published; contact the museum ahead if support is needed. Visitor address: Base Aeronaval Comandante Espora, Bahía Blanca, Buenos Aires, Argentina.
