Taiwan has, for the first time, developed a radar-absorbent material in a breakthrough in stealth technology.

The technology was demonstrated by painting a naval 50t Seagull Class missile boat with the material, which evaded radar surveillance, according to the United Daily News.

The Taiwan Navy declined to comment on the report and it is unclear whether or not the material would be used in the navy’s fleet of ten indigenous 171t missile boats.

The missile boats, armed with four Taiwan-made Hsiungfeng II (Brave Wind) ship-to-ship missiles, are being designed to reduce radar detection and are intended to replace the aging Seagull Class missile boats.
