Dr. Luis María Argaña International Airport lies at Mariscal Estigarribia in the Boquerón Department of Paraguay's Chaco region, a dual military-civil aerodrome best known for possessing the longest runway in the country. Built by Paraguayan military engineers between 1977 and 1986 as part of a planned free-trade zone intended to spur development of the northern Chaco, it remains lightly used today but offers a full-length, ILS-equipped hard runway that makes it a distinctive stop for a simulator pilot exploring remote South American airspace.
This is a dual military-civil aerodrome serving the small town of Mariscal Estigarribia in the Chaco region of Paraguay. It is owned by the national civil aviation authority, DINAC, and operated by the Paraguayan Air Force (Fuerza Aérea Paraguaya). What makes it stand out to a visiting pilot is its runway: at 11,491 feet it is the longest in Paraguay, exceeding even the main runway at the country's principal airport in Asunción, giving the field an outsized physical presence relative to its modest level of traffic.
The airfield sits at Mariscal Estigarribia in the Boquerón Department, in Paraguay's sparsely populated Chaco region, at coordinates 22.0306 S, 60.6226 W and an elevation of 548 feet. It lies close to the town itself. Its dual role as a military and civil facility, and its location near the frontier zone of the Chaco, have made it a subject of periodic government attention regarding border control and regional development, though the sources do not specify a controlled airspace classification.
The field has a single physical runway, 01/19, 11,491 feet long with a hard surface and runway lighting. An ILS is available on runway 01, giving instrument approach capability to what is otherwise a remote strip.
The station callsign is MARISCAL RDO, operating on 118.8 MHz. An ILS is fitted to runway 01, though no specific ILS frequency is given in the available data.
The airfield was constructed by Paraguayan military engineers between 1977 and 1986, conceived as part of a planned free-trade zone intended to help develop the northern Chaco region of Paraguay. It takes its name from Luis María Argaña, a Paraguayan vice-president who was assassinated in 1999, and has been operated by the country's military authorities since construction. Its runway, at 3,500 metres (11,483 feet), was built to be the longest in the country, surpassing even the runway at Asunción's Silvio Pettirossi International Airport, reflecting ambitions for the site that were never fully realised given the region's sparse development.
The aerodrome remains underused relative to its scale, with no regular commercial passenger service currently operating. In 2025 the Paraguayan government was reported to be studying improvements to the airfield, and a commercial carrier, Paranair, was reported to be pursuing certification for flights linking the field to Asunción's Silvio Pettirossi International Airport, though this remained at a study phase. The field continues to be run jointly by the national civil aviation authority and the Paraguayan Air Force.
