Comandante Espora Naval Air Base (Comandante Espora Airport (Bahía Blanca Airport, BACE))

Comandante Espora Naval Air Base, designated BACE by the Argentine Navy, is located approximately 5 kilometers from Bahía Blanca, Argentina, and 25 kilometers from the Puerto Belgrano Naval Base. The military facility shares its infrastructure with the civil Comandante Espora Airport, also known as Bahía Blanca Airport.

Construction of the base began in the 1930s on grounds adjacent to the existing Bahía Blanca Airfield to replace the Puerto Belgrano Air Naval Base, which could not support newer aircraft entering the military inventory. The facility officially opened on 16 June 1939 and was named after Tomás Espora, a naval officer who fought in the 1810–1825 Argentine War of Independence. From 1945 to 1964, the base hosted the Naval Aviation School. In 1970, the Argentine Naval Aviation Command (Comando de la Aviación Naval) relocated its headquarters to the installation.

The installation was opened to civil and commercial aviation in 1968, replacing the civil airstrip at Villa Harding Green. Following expansions to the installations, the facility was released to commercial traffic linking southern Argentina in 1972. Further expansions completed in September 1977 enabled the facility to accommodate aircraft up to the size of a Boeing 767.

The base is operated by the Argentine Naval Aviation and houses the Naval Aviation Command. Joint civil operations continue at the facility, with commercial flights operated by Aerolíneas Argentinas and LADE utilizing the shared runways.
