New Delhi: India and Brazil, on December 9, 2025, signed a landmark defence agreement to exchange critical information on the maintenance and sustainment of Scorpene-class submarines and other naval vessels, opening a major new chapter in their fast-expanding maritime partnership.

The pact was inked during Indian Navy Chief Admiral Dinesh K. Tripathi’s official visit to Brazil, aimed at strengthening strategic cooperation between the two nations.

The tripartite Memorandum of Understanding (MoU), signed by the Indian Navy, Brazilian Navy, and Mazagon Dock Shipbuilders Limited (MDL), is expected to boost life-cycle support for naval platforms while enhancing collaboration in logistics, training, and maintenance.

According to the Indian Navy’s post on microblogging site X, the agreement will also drive technological innovation and deepen Defence Research and Development cooperation between the two maritime powers.

Admiral Tripathi’s visit from December 9 to 12 is focused on consolidating the “robust and growing maritime partnership” that forms a crucial pillar of the India–Brazil Strategic Partnership.

During his stay, he will hold high-level discussions with Brazilian Defence Minister Jose Mucio, Admiral Renato Rodrigues de Aguiar Freire, Chief of the Joint Staff of the Brazilian Armed Forces, and Admiral Marcos Sampaio Olsen, the Commander of the Brazilian Navy.

These discussions will review ongoing maritime initiatives, strengthen operational-level linkages, and identify new areas for collaboration, including naval interoperability, capacity building, and coordinated efforts within multilateral frameworks.

The agenda also includes visits to Brazilian naval commands, shipyards, and bases, showcasing Brazil’s growing maritime capabilities, according to an Indian Navy statement on the visit.

The MoU on submarine maintenance comes at a time when both nations are looking to modernise their navies. India operates Scorpene-class submarines under its Project-75 programme, built by MDL, while Brazil is advancing its own submarine programme, including a nuclear-powered variant.

Shared operational challenges make technical collaboration a natural next step, according to analysts.

India and Brazil have steadily upgraded their defence ties this year. In October, Defence Minister Rajnath Singh hosted Brazilian Vice President Geraldo Alckmin in New Delhi, where both sides discussed co-development and co-production of defence equipment.

They also reaffirmed their commitment to closer military exchanges, joint exercises, and training programmes.

With this new submarine-support pact, India and Brazil are set to strengthen their defence cooperation further, enhancing maritime security and contributing to stability across the global maritime commons.
