The story began to take shape last week when a reader of our publication shared screenshots from the FlightRadar24 and FlightAware platforms. These showed the movement of the Airbus A400M Atlas , registration ZM413 , one of the crown jewels of the British military transport fleet.

The record is irrefutable: on March 10 , the aircraft flew from Mount Pleasant military base to Carrasco International Airport in Montevideo . These kinds of citizen alerts are what allow us to break the information blackout surrounding the "normalization" of foreign military flights in the region.

X-ray of a recurring flight (2025-2026)

This is not an isolated incident. Throughout 2025 and so far in 2026, Agenda Malvinas has systematized a flight pattern that connects the occupied archipelago with key points on the mainland:

This "circularization" of flights demonstrates that the United Kingdom has managed to establish a continental support network that allows it to operate flexibly in the South Atlantic.

Experts' warning: The A400M as an "ear" in the sky

Beyond the transport of personnel or supplies, pilots with extensive experience in highly complex flights have warned this media outlet about a little-known technical capability of these aircraft.

The Airbus A400M is not just a "truck with wings." It is equipped with advanced Signals Intelligence (SIGINT) and Communications Intelligence (COMINT) systems. According to aeronautical sources consulted:

"These aircraft, while transiting international routes or skirting the sovereign coasts of another country, have the technical capability to monitor the electromagnetic spectrum. They can intercept radio communications and, potentially, capture data from cellular networks of local service providers in the areas they fly over."

This capability allows the United Kingdom to obtain strategic information on dialogues and movements in the countries of the region (Argentina, Uruguay, Chile and Brazil) without the need for visible espionage equipment, simply by "taking advantage" of the flight time of its logistical missions.

A challenge to regional sovereignty

The March 10 flight is not just a landing in Montevideo; it is a reminder that the military base in the Malvinas is an operational center with projection and intelligence capabilities over the South American continent.

As long as neighboring countries continue to facilitate these "technical stops" and successive Argentine governments remain silent, the British military infrastructure will continue to consolidate, not only in physical territory but also in the control of information circulating through our skies.
