Nickname: The Classic Golden Avenger
Designer: Anthony Stark
Worn By: Anthony Stark, James Rhodes, Happy Hogan, Eddie March, Carl Walker
Appeared: Tales of Suspense #66

Design Notes :

Shell Composition: Semi-rigid interior/3-D knitted metallic exterior made from actual, ordinary iron provided protection from physical attacks as well as heat, cold, some energy forms, and acid. A new 3-D knitting pattern on a submolecular construction level gives the armor itself more strength, while allowing for the most comfortable suit interior to date including maintaining it's ability to collapse for storage into a briefcase. It used a magnetic field to bring the armor into it's rigid state.
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 siphon power from extreme heat or cold, and solar power.
Control Systems Interface: First integration of cybernetic interface and battle computer (Mark 1).
Weaponry: Unibeam (Mark 3): variable intensity light source. Can be focused for use as a spotlight or fine-focused for use as a laser; Sonic Emitter: generates and broadcasts high frequency sound waves; Palm Repulsors (Mark 3): laser-guided particle beam emission units mounted in the palm of each hand.
Equipment:
*Life Support: earlier models contained pacemaker in the chest-plate that was later removed when Stark had a heart transplant.
*The eye and mouth hole slits could be sealed.
*The suit had oxygen storage for roughly three hours..
*Boot Jets (Mark 4). Incorporates a high-speed gyro-stabilized turbine in each boot.
*Force Field: by expanding the field that keeps the armor rigid, the armor can encase itself in a protective force field that is effective against most forms of attack. He can also used this field to polarize the armor to either attract or repulse other items of magnetic polarity.
*Storage Pods: Detachable batteries that can generate local force field, assume control over machines, and be set to explode.
*Voice Distorter.
*Roller Skates: Collapsed into the boots of the armor.
*Subterranean Equipment.
*Freon Emitters.
*Fire Extinguisher.
*Hologram Emitter: Generates 12 simultaneous images of the armor. It is used to confuse the enemy. He is unable to identify the real armor allowing Iron Man an attack advantage.
*ECM Equipment: The same magnetic field used to keep the armor rigid absorbs the signals from both radar and sonar making the armor invisible to those forms of detection.
*Sensors: Full Band Transceiver, both Audio and Visual; Radar; Sonar; Infrared.

Notes: True electronic incorporation into suit material.The transistors were replaced with cutting edge, microscopic, integrated circuitry.
