India-Japan co-develop UNICORN-based integrated naval radio antenna mast

India and Japan signed an agreement to co-develop a naval integrated mast/radio antenna suite derived from Japan’s UNICORN, which consolidates multiple comms, datalink, IFF, TACAN and ESM-related antennas into a single low-observable mast. The novelty is the localized adaptation and first-ever India–Japan co-development defense project, potentially changing how Indian next-gen warships integrate sensors/comms for reduced signature and improved integration.
