Overview
- The two governments reported the first-ever joint defence technology co-development agreement and adopted a 16-point strategic roadmap to expand defence-industrial cooperation in July 2026.
- The partners agreed in principle to co-develop the Unified Complex Radio Antenna, called UNICORN, which combines communications, radar and electronic-warfare functions in one low‑profile dome to reduce a warship’s radar signature.
- The agreement marks a shift from buyer–seller deals toward technology transfer and co-production, supported by Japan’s revised export stance and India’s Make-in-India push for local manufacturing and tech transfer.
- Practical hurdles remain, including Japan’s strict intellectual-property and export-control rules and India’s procurement and industrial integration needs, and a planned 2+2 ministerial round later in 2026 will work to operationalize the roadmap.
- The move builds on earlier logistics and security ties such as the 2020 RPSS logistics pact and shared FOIP/IPOI priorities and signals closer coordination on maritime security with possible future workstreams for unmanned systems and BrahMos export talks still under discussion.
