Operações de defesa do tráfego marítimo: a evolução e o desafio da defesa do tráfego marítimo no Brasil, da Primeira Guerra Mundial aos dias atuais

Abstract

This paper aims to examine the evolution and challenges of Maritime Traffic Defense operations in Brazil from World War I to the present day, using Brazilian Naval Doctrine as a guiding framework. The study adopts a theoretical approach grounded in the works of Alfred Thayer Mahan and Julian Corbett on sea power and the control of Sea Lines of Communication (SLOCs). It analyzes the Brazilian Navy’s doctrinal and operational structure, highlighting key initiatives such as the Blue Amazon Management System (SisGAAz and the Blue Amazon Maritime Operations and Protection Command (COMPAAz). The dissertation also reviews measures adopted to address contemporary threats, including piracy, naval mine warfare, cyberattacks, and hybrid operations. Furthermore, it includes a comparative analysis of the naval doctrines of other major powers – United States, China, and the United Kingdom – as well as those of South American navies, in order to identify best practices and lessons for Brazil. The findings conclude that despite limitations in resources and assets, the Brazilian Navy has made progress in consolidating capabilities to ensure freedom of navigation and project stability in the South Atlantic.
