Japan Urges India to Speed Up Internal Approval for UNICORN Naval Radar Pact
Japan has formally urged New Delhi to accelerate the internal administrative processing required to implement the Unified Complex Radio Antenna naval radar system agreement. The pact was initially concluded during Japanese Prime Minister Sanae Takaichi's official visit to India in July 2026.
According to Press Information Bureau (PIB), for domestic defense manufacturer Bharat Electronics Limited (BEL), the UNICORN co-development agreement resolves key engineering bottlenecks in designing frequency-selective radomes and multi-band antenna integration under 'Make in India'.
According to Raksha Anirveda, for UNICORN (NORA-50), By enclosing exposed antennas into a unified smooth radome, the UNICORN system eliminates specular reflection and reduces the warship's overall Radar Cross Section by approximately half compared to conventional masts.
A senior Japanese Ministry of Defence official stated on September 29, 2026, that Tokyo is awaiting movement from the Indian defense establishment. Speaking in Tokyo, the official noted that while a basic agreement on the transfer of technology has been established, finalizing the administrative framework remains pending within Indian channels.
According to Militarnyi, bharat Electronics Limited will undertake licensed domestic co-production and integration of the UNICORN system under the 'Make in India' initiative, using core technologies and design provided by Japanese partners.
Strategic Defense Cooperation and Upcoming Drills
The push for the UNICORN radar system comes alongside broader bilateral and multilateral maritime engagements between New Delhi and Tokyo. According to The Hindu, officials confirmed that the bilateral naval exercise Veer Guardian concluded recently, while the upcoming multilateral Malabar naval exercises involving Quad member-states are scheduled to take place near the Sea of Japan before the end of 2026.
Defense discussions between the two nations also incorporate broader minilateral frameworks, including emerging trilateral arrangements involving Indonesia. These initiatives focus on joint maritime domain awareness, technology transfers, and expanded interoperability across vital Indo-Pacific sea lanes.
Evolving Regional Security and Policy Revisions
Tokyo's defense ministry highlighted a shifting regional security environment driven by conflicts in West Asia and Ukraine. These active battlefields have demonstrated the heavy expenditure required to counter unmanned aerial vehicles using expensive missiles, prompting Japan to accelerate the revision of major national security and defense buildup documents originally drafted in 2022.
At the same time, Japanese authorities expressed ongoing concerns regarding regional military activities, pointing to China's rising military expenditures, joint bomber flights with Russia, and a July 2026 submarine-launched ballistic missile test in the South China Sea. Tokyo also noted military cooperation between North Korea and Russia while reiterating its constitutional stance of maintaining minimum defensive capabilities.
Next Procedural Steps
Implementation of the UNICORN radar transfer now awaits completion of internal bureaucratic processing within the Indian Ministry of Defence. Meanwhile, bilateral defense preparations continue ahead of upcoming 2+2 ministerial dialogues and scheduled Quad naval drills later in the year.
