Nickname: Stealth Armor Mark 2
Designer: Anthony Stark
Worn By: Anthony Stark, Carl Walker
Appeared: The Armor Wars -- Iron Man #229

Design Notes :

Shell Composition: Its composed of impact resistant carbon-composites overlayed on top of layered "flex-metal" which can condense itself like a 3-dimensional accordian pleat. Micro-Scale suit tiles fabricated by genetically engineered metal affinity bacteria which assemble themselves in specific orderly arrays, then expire, leaving behind various metallic deposits which form all the metal shapes and micro-electronic circuits. This suit's matrix was formed non-collapsable to allow extra room needed for ECM equipment.
Power Source and Energy Information: Most of this armor used solar power to charge the batteries and run most of the integrated circuitry. However, the pods on the sides were batteries that could maintain the suits functions for a short time. It was able to recharge itself from electrical sources,a thermocouple to syphon power from extreme heat or cold, and solar power.
Control Systems Interface: Cybernetic interface and battle computer (Mark 1).
Weapons:
*Repulsors (Mark 4): This updated Stealth model had repulsors. However, power was limited so the armor could only fire three shots at full power before the power was exhausted.
Equipment:
*Boot Jets: To quash any detectable infrared signature, the armor's exhaust is "washed" by bursts of super cooled air. The micro-turbines on his jet boots posses assisted air liquification devices, rings of liquid oxygen jets, that cool the boot emissions.
Subterranean Equipment: The armor is equipped to tunnel and move below ground.
*ECM: Outer layer of armor has a "camoflauge effect" which allows it to blend into the background.
*Camoflauge Effect: This is a variation of the "chameleon effect" designed in the Silver Centurion Armor. That module interfered with the cybernetic controls of the armor, providing nasty feedback and massive headaches. The camoflauge effect in this suit is entirely manually controlled. It provides the wearer with invisibility to visual or camera detection, but only against backgrounds that are mostly of one color.
Sensors:  Heat (Infrared); Radar; Sonar.

Notes: The Low Observable, or Stealth Armor is used for covert activities when "invisibility" is prudent. This sleek, jet black suit is a polarized metal mesh armor that uses every bit of space for detection and evasion components, and therefore was originally designed with no weapons. Multiple scanning devices and wave modifiers thwart radar rays. In addition, the suit utilizes Force Field technology to render Iron Man electronically invisible. In short, a layer of low density plasma is held in place by a focused magnetic field. The tripole waveform reflects radar nicely, along with a wave modifier that bends the radar around it.
