Early G's had 50mm nose armor. The later production versions added an extra 30mm to this. The later versions went to a standardized front plate of 80mm thickness. Where as older versions had the 30mm plates bolted on so that the old drivers vision slits could be used.
The main superstructure body was widened to extend over the tracks.
A cast armor shield was welded to the roof and front of the cupola to deflect shells.
The corners of the skirting or schurzen were clipped to prevent them from catching on obstacles and being torn off. These were also loosely hung, where earlier version were fixed.
A new mantlet was introduced in 1944 and was a one piece rounded casting and was called a boars head mount. Although some late vehicles still had the built up block mantlet. Late Stugs with the new mantlet had coaxial machineguns which fired through the front of the mantlet and the muzzlebreak was usualy left off on later vehicles.
Zimmerit was used in a waffle or raked pattern.
Loaders roof hatches were rotated 90 degrees so they opened to the sides and a remote control mount for an external mg was placed in the roof ahead of the hatch. The outside hatch could be held open to protect the gunner as he reloaded the roof mg. An angled shield protected the mg and ammo drums from small arms fire.
By 1945 zimmerit as part of production was discontinued on this vehicle. By the end of the war there were vehicles with and without it.
A small "close in defense" weapon similar to those fitted on the panther that could rotate 360 degrees was added.
Ventilator and fan were mounted in the center of the rear roof plate on early vehicles, but them were moved to the vertical rear wall of the superstructure over the engine deck.
Rubber return rollers were replaced with all steel return rollers.
