Japan to Export Cutting-Edge ‘UNICORN’ Naval Stealth Antenna to India

In a significant move reflecting deepening defense ties, Japan has confirmed the export of its advanced naval ship communications antenna, known as the UNICORN, to India. This agreement marks a milestone as the NORA-50 antenna becomes the second defense equipment Japan has exported since lifting its ban on non-lethal defense equipment in 2014. The decision follows Japan’s recent exports of air surveillance radar to the Philippines and the Patriot Advanced Capability system to the US, underscoring Tokyo's increasing role in global defense partnerships.

The UNICORN, officially referred to as the Unified Complex Radio Antenna, represents a leap forward in naval technology. Developed by a collaboration among NEC Corporation, Sampa Kogyo KK, and Yokohama Rubber, this sophisticated antenna system is currently utilized on Japan Maritime Self-Defense Force’s Mogami-class stealth frigates. Its primary function is to detect missiles and drones by sensing radio waves, a critical capability in modern naval warfare.

The antenna's design is particularly notable for its stealth features. The UNICORN consolidates multiple antennas that were previously mounted on separate masts into a single, streamlined support structure. This innovation reduces the radar cross-section, enhancing the ship's stealth capabilities by minimizing its visibility to enemy radar systems. The radome covering further protects the antennas while contributing to the overall stealth profile of the vessel.

Additionally, the optimal placement of antennas within the UNICORN system not only improves the maximum detection range of incoming threats but also simplifies both maintenance and installation. This advanced technology is expected to bolster India’s naval capabilities significantly, integrating seamlessly with the country's defense strategies.

During the recent Japan-India 2+2 Foreign and Defence Ministerial Meeting, officials from both nations expressed satisfaction with the progress on this technology transfer and discussed potential future collaborations in ship maintenance and unmanned ground vehicle robotics. This agreement reflects a broader trend of expanding defense cooperation between the two countries, emphasizing shared interests in enhancing maritime security and technological advancement.

The export of the UNICORN antenna symbolizes a new era of strategic partnership between Japan and India, highlighting the growing synergy in defense technology and mutual commitment to regional stability.
