India–Brazil Sign Defence MoU for Scorpène Submarine Maintenance Support

India and Brazil Seal Tripartite Pact to Enhance Scorpène Submarine Support

India and Brazil have strengthened their growing defence partnership with the signing of a tripartite Memorandum of Understanding between the Indian Navy , the Brazilian Navy , and Mazagon Dock Shipbuilders Limited (MDL) . The agreement marks a major milestone in bilateral naval cooperation, particularly in the shared domain of Scorpène-class submarine operations.

Expanded Maintenance and Lifecycle Collaboration

The MoU focuses on establishing a structured mechanism for technical information exchange , logistics coordination , crew training , and long-term maintenance support for Scorpène submarines. Both countries operate these advanced platforms, making collaboration on lifecycle management crucial for improving deployment efficiency and operational availability. The agreement is expected to enable seamless support ranging from routine servicing to more advanced refits and upgrades.

Strategic Momentum in Maritime Partnership

The pact was finalised during the official visit of India’s Navy Chief, Admiral Dinesh K Tripathi , to Brazil. It aligns with the broader roadmap both nations have outlined for expanding naval cooperation through joint exercises, enhanced information-sharing, and deeper institutional ties. The partnership supports mutual interests in maritime security, underwater domain awareness, and defence industrial collaboration.

Boost for Shipbuilding and R&D Ecosystems

MDL’s proven expertise in building Scorpène submarines, combined with Brazil’s extensive operational experience, creates new opportunities for co-development of maintenance solutions and modernisation programmes. The cooperation is also expected to promote cost-efficiency, strengthen indigenous capabilities, and open pathways for future R&D in undersea warfare technologies.
