A guerra naval contemporânea e a doutrina das ações de superfície: reflexões a partir da guerra da Ucrânia

Abstract

This dissertation analyzes the transformations in Surface Actions in light of new threats emerging from contemporary naval conflicts, with a focus on the war in Ukraine. Grounded in Julian Corbett's classical theory and supplemented by modern contributions from Wayne Hughes and Geoffrey Till, the study explores how traditional principles of naval power have been challenged by asymmetric vectors such as naval drones, electronic warfare, and cyber operations. It examines two key events: the sinking of the Russian cruiser Moskva and Ukraine’s use of unmanned vehicles against the Black Sea Fleet, highlighting the limitations of deterrence based on large platforms and the rise of new naval warfare patterns. From this analysis, lessons are drawn for the doctrinal modernization of the Brazilian Navy, emphasizing the need for multidomain integration, tactical adaptability, and the revision of established concepts. The dissertation concludes that 21st-century naval superiority relies not only on assets but on the ability to operate under contested conditions with agility, intelligence, and continuous innovation.
