PROSUB PROSUB is a Brazilian naval submarine construction and modernization program associated with domestic shipyards, naval research, and defense procurement. It integrates work by Brazilian ministries, shipbuilders, naval architects, and international partners to build diesel-electric and nuclear-powered submarines, involving multiple industrial complexes, universities, research institutes, and shipyards. The program connects strategic initiatives across South America, NATO partners, and global naval engineering centers.
PROSUB involves collaboration among the Brazilian Navy, Ministry of Defence (Brazil), Itaguaí Construções Navais, Naval Group, Amazônia Azul, Centro de Pesquisas institutions, and multiple universities. It engages entities such as Fundação Getulio Vargas, Instituto Tecnológico de Aeronáutica, Instituto de Pesquisa, Fiocruz, Embraer, Vale S.A., and regional administrations in Rio de Janeiro (state), Angra dos Reis, and Itaguaí. The initiative is tied to strategic baselines like the Blue Amazon concept, national industry plans, and regional security dialogues with neighbors such as Argentina, Chile, and Uruguay.
The program traces origins to earlier Brazilian naval projects including cooperation with Germany and historical contacts with firms such as Krupp and later partnerships reflecting post-Cold War realignments with France and Thales Group. Key milestones include agreements signed under administrations led by presidents such as Luiz Inácio Lula da Silva and ministers from the Ministry of Defence (Brazil) and negotiated during summits with representatives from France, United States, United Kingdom, and other defense industrial states. Industrial mobilization involved public companies like Empresa Gerencial de Projetos Navais and regional development agencies collaborating with maritime institutions including Fundação Getulio Vargas and research bodies like Instituto de Estudos do Mar Almirante Paulo Moreira.
Submarine designs draw on French conventional submarine technology and on domestic adaptations conceived by Brazilian naval engineers educated at institutions such as Instituto Tecnológico de Aeronáutica, Universidade Federal do Rio de Janeiro, and Universidade Federal Fluminense. Hull, propulsion, sensor suites, and combat systems reference technologies from DCNS legacy platforms, Thales Group sonar systems, and components interoperable with platforms like A-4 Skyhawk logistics and NAe São Paulo support frameworks. Specifications typically encompass displacement metrics comparable to classes like Scorpène-class submarine and endurance objectives informed by regional patrol needs including protection of resources near Bacia de Campos and Pre-salt (Brazil) deposits. Materials and systems procurement involved companies such as VALE S.A., Siemens, Rolls-Royce, Schneider Electric, Embraer, and research labs tied to Instituto Nacional de Pesquisas Espaciais.
Operational deployments are planned for littoral and blue-water patrols in areas adjacent to São Paulo (state), Paraná (state), and the South Atlantic arc near Trindade and Martin Vaz. Projects include crew training programs with instruction at facilities associated with Escola Naval (Brazil), simulation partnerships with institutions like Centro de Simulação Naval, and logistics chains involving ports such as Port of Rio de Janeiro and Port of Angra dos Reis. Exercises coordinate with regional navies including Argentine Navy, Chilean Navy, Uruguayan Navy and with extra-regional navies such as the French Navy, Royal Navy, United States Navy, Royal Australian Navy, and the Indian Navy in combined maneuvers and interoperability trials.
The program featured industrial cooperation agreements with France and private firms including Naval Group and has drawn interest from countries in Africa, Southeast Asia, and Latin America. Export implications reference comparative platforms like the Scorpène-class submarine sales to Chile, India, and Malaysia. Technology transfer, licensing, and joint ventures involved entities such as DCNS, Thales Group, Siemens, and academic partners like Universidade de São Paulo to build local capacity. Strategic dialogues occurred in forums including meetings with delegations from South Africa, Indonesia, Egypt, and Pakistan exploring regional submarine capabilities.
Safety regimes align with standards influenced by international practice from bodies associated with International Maritime Organization and naval safety doctrines familiar to navies like the United States Navy and Royal Navy. Environmental assessments consider impacts on marine protected areas such as the Fernando de Noronha archipelago and fisheries near Atol das Rocas, with input from research groups at Fundação Oswaldo Cruz and marine biology departments at Universidade Federal do Rio de Janeiro and Universidade Federal de Pernambuco. Sea trials and testing phases were coordinated with port authorities in Rio de Janeiro (city), monitored by agencies similar in remit to IBAMA and conducted alongside academic oceanography centers like Instituto Oceanográfico.
Future trajectories include expansion toward a nuclear propulsion demonstrator integrated with civilian research reactors and partnerships involving research institutes like Instituto de Pesquisas Energéticas e Nucleares and technology providers comparable to AREVA and Westinghouse Electric Company. Upgrades focus on enhanced AIP systems, integration of advanced sonar from suppliers akin to Thales Group and Saab AB, and compatibility with unmanned underwater vehicles from vendors similar to Kongsberg Gruppen and Bluefin Robotics. Strategic planning will engage ministries and institutions including Ministry of Defence (Brazil), regional universities, and international partners to sustain workforce development and industrial base expansion.
