India and Japan have launched their first joint defence technology project by agreeing to co-develop the UNICORN (Unified Complex Radio Antenna) system for Indian Navy warships.
The advanced antenna combines multiple communication and surveillance systems into a single integrated mast, helping ships become harder to detect on enemy radar while improving operational efficiency.
The project will be jointly developed with Japanese technology and manufactured in India, marking a major step in defence cooperation between the two countries. Announced during the India-Japan summit in New Delhi, the agreement reflects growing strategic trust and supports a shared vision for a secure, stable and rules-based Indo-Pacific.
The partnership also signals closer collaboration in advanced defence technologies and maritime security.
