The tactical reconnaissance TR-3B first operational flight was in the early 90s. The triangular shaped nuclear powered aerospace platform was developed under the Top Secret Aurora program. The TR-3B vehicles outer coating is reactive to electrical Radar stimulation and can change reflectiveness, radar absorptiveness, and color.
This polymer skin, when used in conjunction with the TR-3Bs Electronic Counter Measures and, ECCM, can make the vehicle look like a small aircraft, or a flying cylinder or even trick radar receivers into falsely detecting a variety of aircraft, no aircraft, or several aircraft at various locations.
A circular, plasma filled accelerator ring called the Magnetic Field Disrupter, surrounds the rotatable crew compartment and is far ahead of any imaginable technology.
