• A Memorandum of Implementation was signed at the Embassy of India, Tokyo between the governments of India and Japan, for co-development of UNICORN mast for fitment onboard Ships of Indian Navy.

• The Unified Complex Radio Antenna (UNICORN) is a mast with Integrated Communication systems which will help improve the stealth characteristics of Naval Platforms.

• It is India’s first military technology transfer pact with Japan.

• The Indian Navy is pursuing the induction of these advanced systems which will be co-developed by Bharat Electronics Limited in India with Japanese collaboration.

• When implemented, this would be the first case of co-development / co-production of Defence Equipment between India and Japan.

Unified Complex Radio Antenna (UNICORN)

• The Unified Complex Radio Antenna (UNICORN) is an advanced integrated communication system designed to enhance the stealth capabilities and operational efficiency of naval vessels. 

• It consolidates multiple communication antennas into a single, state-of-the-art radar dome, known as a radome, offering several advantages over traditional mast systems.

Key Features:

• UNICORN reduces the radar cross-section of ships by integrating various antennas into a single structure, minimising electronic signatures and enhancing stealth.

• The streamlined placement of antennas improves the maximum detection range for incoming radio signals, ensuring better situational awareness.

• Its design reduces the complexity of installation and facilitates easier maintenance compared to conventional systems.

• UNICORN is the result of collaboration between three Japanese companies — NEC Corporation, Sampa Kogyo K.K, and The Yokohama Rubber Co., Ltd. 

• This cutting-edge system is currently installed on Mogami-class frigates of the Japan Maritime Self-Defense Force, showcasing its role in modernising Japan’s naval defense technology.

• By integrating advanced communication systems and reducing the radar profile of vessels, UNICORN exemplifies the future of naval innovation.
