Since the early 2000s there has been talk in the military journals and AW&ST about the use of electro-chromatics for future fighter aircraft and/or UCAVs. This tech would be piled on top of stealth masking to reverse image the sky and ground to deceive missile operators on the ground and interceptor pilots in the air. EC works by using a layer of embedded tiny cams to take the images from one surface of the aircraft and move it to the other. Enemy aircraft searching above see what appears to be the ground for the top of the aircraft while missile operators and spotters would see the sky instead of the bottom of the aircraft. This would work better on a UCAV due to size and configuration, esp. with deltas... but also manned craft (pref. a flying wing or delta). Lockheed has a rumored Blue Bolt program (from a bolt out of the blue saying). Meant to get in quickly undetected, strike, and then get out quickly. Also could come in handy for landing troops IF EC could mask a cargo plane. OIC around 2030 IF funded and accepted.
