Invisible tank

A tank that hides in front of your eyes is the star of the show at Defence and Security Equipment International, the arms and technology show on now at London's ExCel centre.

The invisibility cloak tank designed by BAE Systems uses patented “Adaptiv” technology to trick the opposition's infra-red cameras and goggles. The technology is based on hexagonal panels that can change temperature rapidly, while the outer skin displays background scenery that is picked up by on-board cameras. Alternatively, the hexagons can mimic another vehicle to fool the enemy, or display identification tags to avoid friendly fire.
