Overview
- Japanese Defence Minister Shinjiro Koizumi visited the Western Naval Command in Mumbai on Wednesday and met Navy chief Admiral Krishna Swaminathan and other senior officers before boarding the indigenous destroyer INS Chennai.
- Koizumi is scheduled to hold bilateral talks with Indian Defence Minister Rajnath Singh in New Delhi on Thursday to set a roadmap for deeper maritime security cooperation and defence-technology collaboration under the Make‑in‑India framework.
- Officials from both countries reported an agreement in principle on the technical details of the Unified Complex Radio Antenna (UNICORN), the warship communications mast first announced as an India–Japan co‑development in November 2024.
- Tokyo’s April change to the Three Principles on Transfer of Defence Equipment and Technology removed long-standing limits on transfers, opening the door to wider cooperation on platforms such as specialised seaplanes and conventional submarines with Japanese firms including ShinMaywa.
- If talks convert agreements in principle into formal contracts and export clearances, India could gain faster access to Japanese technologies while expanding domestic shipbuilding and systems work, though final steps will require legal approvals and industrial agreements.
