During Stark's lifetime, he gains more money and technology becomes better too, therefore giving him the chance to upgrade the Iron Man armour. The Mark III armour has many different upgrades, which cost money to research and make but create a better suit for Stark to use. Below is a list of upgrades, which the Mark III armour can acompany:
Stark Industries' signature targeting systems were added to the Mark III. Each projectile weapon, carrying its own microcomputer, could communicate wirelessly with the targeting system even after launch, tracking the most mobile targets and even changing targets en route. The Mark III System offers remarkable durability without compromising mobility. This armor was constructed as a flexible foundation from which further improvements can be made.
Stark confirmed that this lightweight yet extraordinarily strong alloy shell consists of 95.5% titanium and 4.5% gold and is coated on the interior with a dense, high-tensile synthetic fiber, similar to Kevlar 49.
