BAE Systems’s Adaptiv technology enables objects as big as tanks to completely vanish from view. At night, militaries use infrared to see in the dark without being seen themselves, but IR only sees heat, which means it can be fooled. This system constantly maps its surrounding heat signature and mimics it, effectively making the tank completely invisible to infrared. Of course, it can also be made to look like any other object such as a rock or trees. BAE says Adaptive also adds armor to tanks and can be installed at a comparatively low price, and could be ready for production within two years.
