Type: Assault gun.

History:

The StuG 40 Ausf G was the last production series of the Sturmgeschuetz III. Rolling off the assembly-line in December 1942, the Ausf G was produced until the end of the war, with no major design changes.
In 1942, the decision was made to use Panzer 3 chassis for StuG production, since the PzKpfw III was being phased out and replaced by the Panzer V Panther. In response to this request, 165 PzKpfw III Ausf M chassis were used as chassis for StuG 40 Ausf G, with production from February to November 1943.

In 1944, 173 PzKpfw III, returned to the factory for overhaul, were converted to StuG 40 Ausf G.

The hull of the Ausf G remained unaltered from the design used for the Sturmgeschuetz Ausf F/8. The main design changes were to the superstructure. The roof was altered, and a cupola with periscopes was added for the commander, and a shield for the machine-gun was installed in front of the loader’s hatch. The superstructure sides were now slanted, and slanted plates were added to protect the front of both panniers.

Various improvements were instituted during the production run, including introduction of the Saugkopf (sow’s head) gun mantlet late in 1943, the coaxial MG34 machine-gun early in 1944, and the Nahverteidigungswaffe (close-in defense weapon) and remote-control machine-gun to the superstructure roof late in spring 1944.

Vehicles issued to Funklenk-Kompanien (Remote-Control Companies for Tracked demolition charges like Goliath etc) were fitted with an additional radio aerial on the left front of the fighting compartment roof.

Twenty-eight independent Sturmgeschuetz detachments, four divisional Sturmgeschuetz detachments, two 2nd Funklenk companies and twelve Sturmgeschuetz platoons (with Luftwaffe Field Divisions) were at the front in Russia at the start of the Battle of Kursk. From the start of the war, the use of the assault-gun spread from Sturmgeschuetz detachments to the other types of formations, including Panzer detachments, Panzerjaeger (tank destroyer) detachments and Funklenk companies and detachments.

Users: Germany, Finland.

  1. What is a “Stug 40”? I’ve only ever heard it called a “StuG III”. Does this information only apply to in-game vehicles then, or what? I wish people would make these things clear. The stats “as played” are not always the same as the real machine, and many sources just list whatever armor, speed, power that the game designers happened to give their representation of the vehicle. Also misleading to list 3 different MGs. Seems to be saying there was a roof gun, a coax and a bow gun, or something. It had an MG34 or MG42 OR a remote-controlled MG34. Never had any bow gun that I know of (although I always wondered why not. The assistant driver is the only crewman without immediate duties, and he has a perfect place to mount a ball-mount MG in front of him. I am sure they didn’t expect to be using the main gun and the MG at the same time very often, but just in case it’d be nice to keep the loader at his station while using the roof gun. I guess the co-driver can climb back and help load the gun or take over the MG if need be, but still seems a pain. Mostly I think they just tried to stay outside of MG range, to keep safe, so it’s mostly a backup weapon, or an area-denial weapon. But they put bow guns into many other vehicles and they worked okay. I guess.
