Navy and Petrobras Work Together Against Espionage and Sabotage in the Submarine Routes of the Pre-Salt, Essential for Brazil’s Energy Security.
While the eyes of the world turn to the surface, a silent battle takes place in the depths of the South Atlantic. The Brazilian Navy and Petrobras work together every day to protect the underwater structures that support not only oil production in the pre-salt but also the security of the country’s strategic data.
This constant vigilance has gained even more importance in light of the increased risks such as espionage, cyberattacks, and sabotage.
Why Is the Pre-Salt a Target for Espionage?
The cooperation between the two institutions has strengthened in recent years precisely to prevent these invisible threats from compromising systems essential to the economy and national sovereignty.
-
Brazil could become a global oil powerhouse with reserves jumping from 17 billion to 23.5 billion barrels, investments of US$ 30 billion per year, and exploration in the Equatorial Margin that could extend Brazilian production until 2042.
-
While Brazil discussed the transition, Petrobras unlocked 11 new platforms in the pre-salt until 2027 — Búzios alone receives 6 FPSOs and targets 1 million barrels/day.

The reason is clear: nearly 97% of the country’s digital communications pass through these submarine routes, including internet, financial operations, and sensitive information.
The pre-salt represents more than 75% of the national oil and gas production. But protecting this wealth goes far beyond visible platforms.
The real targets are the communication cables, oil pipelines, and sensors installed thousands of meters deep.
According to the International Telecommunication Union (ITU), any failure or attack on this network can cause a digital blackout: a shutdown of the banking system, satellite failures, and disruptions of essential services.
And the attacks, increasingly sophisticated, do not use missiles — they are carried out through technical sabotage, cyber invasions, and industrial espionage.
Navy Invests in Cutting-Edge Technology to Protect the Depths
To face these silent threats, the Brazilian Navy has intensified the use of advanced technologies.
Autonomous Underwater Vehicles (AUVs), fixed monitoring stations, and the Blue Amazon Management System (SisGAAz) are operational, tracking activities at sea in real time.
“The protection of these infrastructures cannot be neglected. The impact of an attack could paralyze everything from agribusiness to satellite coordination,” warns Rear Admiral Luiz Roberto Barcellos, an expert in cyber defense.
Strategic Partnership Between Navy and Petrobras Against Espionage and Hybrid Threats
Petrobras, with its experience in deep operations, works directly with the Navy to strengthen the security of submarine routes.
The joint effort includes investments in signal intelligence (SIGINT), robotics, remote sensing, and real-time digital surveillance.
Analyst Fernanda Silva, from the Igarapé Institute, emphasizes that this is “multidimensional security that involves physical, cyber, and environmental threats.”
In other words, the defense of the pre-salt does not depend solely on weapons but also on innovation, cooperation, and strategic planning.
With immense energy potential, the pre-salt attracts the interest of foreign powers and transnational companies. According to researcher Leonardo Perin Vich, from the Superior War School, “it is essential to establish partnerships to ensure the security of the submarine routes crossing the South Atlantic.”
Espionage in deep waters is a reality that demands constant vigilance. Therefore, operations such as the Guarantee of Law and Order (GLO) are mobilized whenever necessary, ensuring a quick response to any threat to national sovereignty.
The protection of wealth at the bottom of the sea requires more than ships and submarines.
Brazil needs science, cutting-edge technology, and integration between civil and military agencies. And, of course, continuous investments.
