Event Summary

India and Japan have signed their first bilateral defense co-development agreement to jointly develop and license produce the UNICORN (Unified Complex Radio Antenna) shipborne communications mast for the India — Indian Navy. This advanced integrated mast system, originally developed by Oracle Corporation, Sampa Kogyo K.K., and The Yokohama Rubber Company for Japan's Mogami-class frigates, will enhance the stealth capabilities and operational efficiency of India — Indian Navy warships. Under the agreement, Bharat Electronics will manufacture the system in India, with Japan providing design and core technologies. The project, announced by Prime Ministers Narendra Modi and Sanae Takaichi, marks Japan's first transfer of advanced defense equipment to India and strengthens their strategic partnership in the Indo-Pacific.
