America needs a UV interference system
The US military requires a device that can interfere with guidance systems that operate in the ultraviolet. Most likely, these will be traps resembling modern thermal ones. When they are ejected from a combat aircraft, infrared homing heads of missiles are blinded.
The UV interference system will complement the stealth technologies, which are applied, for example, on the fifth-generation F-35 fighter. This aircraft has a small radar and infrared signature (visibility), but it can easily be detected in the ultraviolet range.
Now homing heads of MANPADS missiles (man-portable air defense systems) use the ultraviolet spectrum to detect a fighter against the sky. Initially, using the infrared range, the rocket is “closed” on the target, and then when the infrared traps are approaching and shooting, the rocket uses a UV sensor. At the moment, cheap ultraviolet cameras that detect infantry, aircraft, armored vehicles and other objects well hidden in the visible and IR ranges are very popular.
The main task of the ultraviolet trap is to effectively combat such guidance systems, for example, by emitting a cloud of material that absorbs UV rays. The request of the US Navy, in particular, refers to a cloud of quantum dots (tiny crystals emitting light) or metamaterials that are able to control the movement of light rays. While the date of this development is unknown and when there will be the first deliveries of new devices.
