The Argentine Naval Prefecture, in Spanish Prefectura Naval Argentina or PNA, is a service of the Argentine Security Ministry charged with protecting the country's rivers and maritime territory. It therefore fulfills the functions of other countries' coast guards, and furthermore acts as a gendarmerie force policing navigable rivers.

According to the Argentine Constitution, the Armed Forces of the Argentine Republic cannot intervene in internal civil conflicts, so the Prefecture is defined as a civilian "security force of a military nature". It maintains a functional relationship with the Ministry of Defense, as part of both the National Defense System and the Interior Security System. It therefore maintains capabilities arising from the demands required by joint military planning with the armed forces.



The Prefecture's predecessor is the ports service founded by the first autonomous Argentine government in June 1810, six years before Argentina declared independence. In Argentina this is considered the official founding date of the PNA. The first commander of the force was Colonel Martin Jacobo Thompson, a Porteño of partially English descent who had served against the British in the invasions of 1806–7. Thompson was given the title of "Captain of Ports" (Spanish: "Capitán de Puertos").

Although the PNA traces itself back to its predecessor of 1806, the modern Prefecture was in fact founded in the late nineteenth century as the "National Maritime Prefecture" on the initiative of Manuel Florencio Mantilla, a well-known Argentine senator who was also a respected academic and intellectual.

Falklands War

The Prefecture had a minor role in the Falklands War (Spanish language: Guerra de las Malvinas ). As with other Argentine military services, participation in this conflict is given considerable weight in the institutional memory of the service.

Two PNA patrol vessels, the Islas Malvinas (GC-82) and the Rio Iguazu (GC-83), were sent to provide an Argentine coastguard service to the islands. According to Argentine sources, Rio Iguazu came into contact with a British Sea Harrier aircraft on 21 May and one member of the vessel's crew was killed while firing a 12.7 mm machine gun at the British jet. The ship ran aground, but most of its cargo -among them two 105 mm howitzers- was recovered later. The crew of the patrol boat claimed the shooting down of the aircraft, but this was later proved to be unfounded. The sortie was actually carried out by two Sea Harriers of 800 Naval Air Squadron, Nº XZ460 and XZ499, which strafed the vessel with 30 mm cannon fire.[1] The patrol vessel Islas Malvinas was captured and operated by the Royal Navy, as HMS Tiger Bay.

Illegal fishing

Today the Prefecture is constantly battling illegal fishing vessels in the Argentine Exclusive Economic Zone (ZEE),[2] mostly from eastern countries. The Argentine Naval Aviation also collaborates in detection of such ships with their P-3 Orion and Beechcraft 200 Cormoran maritime surveillance aircraft.

Chian-der 3 incident

The Sinking of the Chian-der 3 was an incident which occurred on 28 May 1986 when the Taiwanese flag naval trawler Chian-der 3 was detected, tracked, shot, set on fire and finally sunk by the PNA. The sinking was carried out by PNA vessel GC-28 "Prefecto Derbes". Two Taiwanese fishermen were killed; four others were injured. The Taiwanese fishermen's union called the incident a "barbaric act" and the British government condemned it as "unjustifiable and excessive".



Guardacostas Building

The PNA is subordinate to the Ministry of Interior. The organization is headed by the National Naval Prefect (Prefecto Nacional Naval), currently Prefect-General Carlos Edgardo Fernandez, assisted by the Deputy National Naval Prefect (Subprefecto Nacional Naval), currently Prefect-General Ricardo Rodriguez.

The Prefecture's main facility is located in the Edificio Guardacostas (which translates as "the Coastguard Building") at 235 E. Madero Avenue, Buenos Aires.

The PNA headquarters is divided into three main departments, each headed by a Director-General with the rank of Prefecto General. These are each divided into a number of directorates, each headed by a Director with the rank of Prefect-General (Prefecto General).
