The Stealth armor is another of the specialized suits of armor developed by Stark for specific missions, similar to the Space Armor; indeed, its creation was inspired due to him being tracked by radar during his use of the Space Armor. The Stealth Armor was designed using current "stealth" technology to allow Iron Man to foil detection devices and slip unknown in and out of restricted areas. This sleek, jet black suit (composed of impact resistant carbon-composites overlaid on top of layered "flex-metal" which can condense itself like a 3-dimensional accordion pleat) was a polarized metal mesh armor that uses every bit of space for detection and evasion components, and therefore was originally designed with no weapons. A bubble-shaped "backpack" was also incorporated into the armor to expand the space available for the stealth systems. Most of this armor used solar power to charge the batteries and run most of the integrated circuitry, though the pods on the sides were batteries that could maintain the suit's functions for a short time. It was able to recharge itself from electrical sources, a thermocouple to siphon power from extreme heat or cold, and solar power. The suit used force field technology to render Iron Man electronically invisible- a layer of low density plasma would be held in place by a focused magnetic field, and the tripole waveform reflected radar, along with a wave modifier that bent the radar around it. To quash any detectable infrared signature, the armor's boot-jet exhaust was "washed" by bursts of super-cooled air. The micro-turbines on his jet boots possess assisted air liquification devices; rings of liquid nitrogen.
