New Delhi: UNICORN stealth naval radio antenna system has entered a new phase as both countries deepen their defence technology partnership. India and Japan are working together on Project UNICORN, an advanced stealth naval radio antenna system designed to improve the Indian Navy’s survivability, communication security, and operational effectiveness. The project marks the first major defence co-development initiative between the two nations and supports India’s maritime modernization goals in the Indo-Pacific region.
The project is expected to help Indian warships become harder to detect by enemy radar while improving communication and electronic warfare capabilities.
What Is Project UNICORN
Project UNICORN stands for Unified Complex Radio Antenna. It is an advanced integrated mast system that combines multiple antennas, sensors, and communication systems into a single enclosed structure.

Traditional warships use several exposed antennas mounted across the ship. These antennas increase radar reflections and make vessels easier to identify.
UNICORN replaces these scattered systems with a streamlined mast, reducing radar signatures and improving stealth performance.
Why UNICORN Project Is Important For The Indian Navy
Modern naval warfare increasingly depends on stealth. Warships that are difficult to detect gain a significant advantage during surveillance, reconnaissance, and combat operations. UNICORN helps achieve this by reducing the radar cross-section of naval vessels.
The system also improves secure communications and electronic warfare capabilities, which are critical in contested maritime environments.
India And Japan Strengthen Defence Cooperation
India and Japan have steadily expanded defence ties over the last decade. The UNICORN project represents the first major defence hardware co-development program between the two countries. Officials from both nations have described it as a significant milestone in their strategic partnership.
A Memorandum of Implementation for UNICORN cooperation was signed earlier, laying the foundation for technology transfer and joint development activities.
High-Level Defence Talks Support The Project
The project has received support through regular India-Japan defence dialogues and strategic meetings. Both countries continue to emphasize a free, open, and rules-based Indo-Pacific region while expanding maritime security cooperation.
How UNICORN Technology Works
UNICORN integrates various communication and surveillance functions into one mast. These include:
- Tactical data links
- Communication systems
- Radar-related equipment
- Identification Friend or Foe (IFF) functions
- Electronic support measures
Bringing these systems together reduces antenna clutter and lowers the ship’s radar visibility.
Improved Stealth And Survivability
The biggest advantage of UNICORN is reduced radar detectability. Enemy forces often use radar signatures to identify and track warships. By minimizing exposed structures, the system makes identification much more difficult. This can improve survivability during high-risk naval missions and enhance operational flexibility for the Indian Navy.
UNICORN Project: Technology Already Proven In Japanese Warships
The UNICORN mast system has already been deployed on Japan’s advanced Mogami-class frigates. These warships are known for their low-observable design and modern naval technologies. The successful deployment demonstrates the maturity and operational readiness of the system. The Indian Navy is expected to benefit from Japan’s experience in integrating stealth technologies into frontline warships.
Role Of Indian Industry In The Project
India’s defence industry is expected to play a major role in the program. The project aligns with the Make in India initiative and aims to strengthen indigenous shipbuilding and defence manufacturing capabilities. Technology transfer and local integration could help Indian companies gain expertise in advanced naval stealth systems.
Strategic Benefits For India
The Indo-Pacific region is becoming increasingly important for global security and trade. Advanced stealth technologies like UNICORN can improve India’s maritime awareness, fleet survivability, and ability to operate in contested waters.
The project also demonstrates growing defence cooperation between two major Indo-Pacific partners.
