Chinese firm selling stealth 'core technology by the kilogram' to make drones almost invisible to radars — spray-on coating is almost affordable by F-117 standards, slashes reflected radar power by 50%

• Star-Navi, a Shenzhen-based company, is now selling access to stealth drone tech that normally has a multi-billion-dollar barrier to entry as a standard package containing a spray gun
• The tech essentially makes a drone's radar cross-section smaller and harder to track on modern radars
• The coatings are being marketed as the XRAM-C series, with 3 different variants being offered that deal with different threat radar frequencies.

While modern drone technology has evolved considerably from the rudimentary designs we first saw over a decade ago, it is becoming an increasingly important industry for the military in most countries to use and counter alike.
