In Earth-TRN840, the Iron Man Armor Model 7 armor resembled the Iron Man Armor Model 43.
This special sneaky armor may let Iron Man scout behind enemy lines without being seen, but it still packs quite a punch! When Iron Man (Teen Tony) and James Rhodes battled Stockpile, their employer Morgan Stark attempted to remotely control a number of older armors including a stealth model.
By this point, Tony had managed to upgrade the suit to give it limited weapons capability where the original was basically defenceless. The Stealth Armor was later used by Stark to infiltrate Soviet airspace during the first Armor Wars. It was used by Stark to infiltrate the Heaven's Hand fortress in the area formerly known as East Germany. Designed after Tony was detected approaching a Roxxon space station using the Space Armor, the Stealth Armor was created to focus on stealth over offensive weaponry.
