Low-observable technology, often known as stealth technology, hides soldiers, aircraft, ships, submarines, missiles, satellites, and ground vehicles from radar and infrared sensors (preferably invisible). Stealth coating reduces radar cross section and makes aeroplanes harder to detect. Stealth planes employ radar-absorbing polymers. Stealth technology camouflages vehicles and buildings from radar. A radar-absorbent material may alter an items radar cross section at specific radar frequencies, but it does not make it "invisible" at any frequency. Stealth technology reduces radar reflections using radar-absorbing materials and geometry. Polymer composite-based stealth are graphene, carbon black, carbon nanotubes, and carbon fibres as carbonaceous material and filler. Stealth coating resin market size is based on epoxy, polyurethane, and polyimide. It also protects automobiles against ultraviolet rays, chips, scratches. Tanks and ships employ stealth coating technology to avoid hostile radar. The coating absorbs and scatters radar radiation, hiding the device. Military aircraft uses stealth coating to avoid radar. Commercial airlines are using stealth coating technologies to improve safety and security. The coating reduces aircraft drag and weight, improving fuel economy. Stealth coating absorbs radar signals, hiding the aircraft from radar detection systems. Military and private planes utilise it for security. Stealth coating reduces radar detection by absorbing or deflecting radar emissions. Military operations need stealth and secrecy, but civilian aviation may employ this technology to avoid hijackings and identify unlicensed planes radar-absorbent polymers cover stealth aircraft. These and other design features may weaken the aircraft's radar signal.
