Argentine Naval Prefecture

TheArgentine Naval Prefecture, also known as the Prefectura Naval Argentina, functions as the country's maritime law enforcement and coast guard agency. Its primary duties include ensuring safety of navigation, conducting search and rescue operations, and protecting the marine environment. The agency patrols Argentina's territorial waters, inland rivers, and littoral zones to prevent smuggling, illegal fishing, and drug trafficking. It also provides maritime security for ports and coastal installations, and assists other government bodies during natural disasters or emergencies.

Operating across Argentina's extensive Atlantic coastline and its major river systems such as the Paraná and Uruguay, the Prefecture maintains a widespread presence through numerous stations, detachments, and mobile units. Its operational reach enables it to respond swiftly to incidents occurring far from major urban centers, covering both remote coastal areas and densely populated river ports. The agency's fleet consists of patrol vessels, fast interceptors, and specialized craft suited for different hydrographic conditions. Aviation assets support surveillance and rescue missions over large maritime expanses where surface units may be delayed.

Distinguishing the Argentine Naval Prefecture from other security forces is its dual role as both a civilian police organization and a maritime safety authority, granting it authority to enforce laws on water while also regulating navigation standards. The agency maintains specialized divisions for underwater operations, diving, and maritime investigations, which enhance its capability to confront complex crimes such as human trafficking and environmental violations. It also participates in regional maritime cooperation frameworks, sharing intelligence and best practices with neighboring countries' coast guards and international organizations. These competencies allow the Prefecture to address a broad spectrum of threats ranging from conventional smuggling to emerging challenges like cyber‑enabled maritime crime.

Administratively, the Prefecture reports to the Ministry of Security and is structured as a federal agency under the national executive branch, distinct from the armed forces but often coordinating with naval and air force units during joint operations. Its headquarters is located in Buenos Aires, from where strategic direction and resource allocation are managed. A notable event in its recent history occurred on 12 August 2019, when hackers breached government systems, exfiltrated hundreds of gigabytes of sensitive data, and hijacked the Prefecture's official Twitter account to disseminate stolen material and false claims about a British military attack on Argentine vessels. This incident highlighted the intersection of cyber threats with traditional maritime security responsibilities.
