A Shenzhen-based company, Star Navi, is selling radar-absorbing coatings that could make drones harder to detect and track on modern radar systems.
The technology is being marketed through the XRAM C series and is aimed at reducing the radar cross section of drones, aircraft, and naval platforms. The coatings are being offered in standard containers and packages that include spray equipment.
Drones have become an increasingly important part of modern warfare, with recent conflicts showing how low-cost unmanned systems can cause serious damage to stronger conventional forces.
At the same time, counter-drone systems have become more advanced. These systems often use radar, radio frequency sensors, cameras, jamming tools, and directed energy weapons to detect, track, and neutralize hostile drones.
Detection remains the most important part of ancounter-dronene response. Small drones are already difficult to track because of their limited radar profile, and radar-absorbing coatings could make that challenge more serious.
Star Navi’s XRAM C series includes three variants designed for different radar frequency ranges.
XRAM C105 is optimized for X and Ku bands and is aimed at reducing the effectiveness of counter-drone systems.
XRAM C112 is optimized for S and C bands and is aimed at reducing detection by surveillance radar.
XRAM C113B offers broader coverage across C and X bands for wider radar signature reduction.
The company says the coating can withstand 250 degrees Celsius for 100 hours without degradation. It is being sold in 1 kg, 5 kg, and 10 kg containers.
The easier availability of radar-absorbing coatings raises concerns because stealth technology has traditionally been restricted to advanced military programs.
If such coatings become widely accessible, smaller militaries, militias, or non-state actors could gain access to tools that make drones harder to detect.
That could complicate air defense planning and increase the pressure on counter-drone systems that rely heavily on radar signatures.
Star Navi is not the only company working in this area. Researchers and defense suppliers in other countries are also developing radar-absorbing materials for drones and aircraft. Companies such as CFI Solutions and Intermat Defense are active in the market, with Intermat Defense supplying US military contractors, including Lockheed Martin and Northrop Grumman.
Interest inlow-costt stealth coatings is expected to grow as drones become more common in military and security operations.
The Russia-Ukraine war and the US-Iran war have shown how drones can reshape conflict by giving forces a cheaper way to strike targets, conduct surveillance, and pressure stronger opponents.
As drones become more capable, both drone technology and counter-drone technology are advancing quickly.
The availability of spray-on radar-absorbing coatings suggests the next phase of drone warfare may not only focus on better sensors, longer range, or heavier payloads. It may also focus on making even low-cost drones harder to find.
