PE/Resin Detail:



"Added extra details like tools, jack block etc. Backdated to an earlier version with earlier exhaust, diffreent arrangement of wheels and return rollers.
Would have been a very nive kit with better tracks and a little more detail included."

The Sturmpanzer (also known as Sturmpanzer 43 or Sd.Kfz. 166) was a German armoured infantry support gun based on the Panzer IV chassis used in the Second World War. It was used at the Battles of KurskAnzioNormandy, and helped to put down the Warsaw Uprising. It was known by the nickname Brummbär (German: "Grouch")[Note 1]by Allied intelligence,[2] a name which was not used by the Germans. Just over 300 vehicles were built and they were assigned to four independent battalions.

The Sturmpanzer was a development of the Panzer IV tank designed to provide direct infantry fire support, especially in urban areas. The result was the Sturmpanzer, which used a Panzer IV chassis with the upper hull and turret replaced by a new casemate-style armored superstructure housing a new gun, the 15 centimetres (5.9 in) Sturmhaubitze (StuH) 43 L/12 developed by Skoda. It fired the same shells as the 15 cm sIG 33 heavy infantry gun. Thirty-eight rounds, with separate propellant cartridges, could be carried. It used the Sfl.Zf. 1a sight. The combined weight of the shell and cartridge (38 kilograms (84 lb) for an HE shell and 8 kilograms (18 lb) for a propellant cartridge) made the work of the loader arduous, especially if the gun was elevated to a high angle.[1]

An MG 34 machine gun was carried that could be fastened to the open gunner's hatch, much like the arrangement on theSturmgeschütz III Ausf. G. Early vehicles carried a MP 40 sub-machine gun inside, which could be fired through firing ports in the side of the superstructure.

The driver's station projected forward from the casemate's sloped frontal armor plate and used the Tiger I's Fahrersehklappe 80 driver's sight. The fighting compartment was (badly) ventilated by natural convection, exiting out the rear of the superstructure through two armored covers. Sideskirts were fitted on all vehicles.[3]

Early vehicles were too heavy for the chassis, which lead to frequent breakdowns of the suspension and transmission. Efforts were made to ameliorate this from the second series onwards, with some success.[4]

In October 1943 it was decided that the StuH 43 gun needed to be redesigned to reduce its weight. A new version, some 800 kilograms (1,800 lb) lighter than the StuH 43, was built as the StuH 43/1. Some of the weight was saved by reducing the armor on the gun mount itself. This gun was used from the third production series onwards.[4]

Zimmerit coating was applied to all vehicles until September 1944.[5]

Production series


Production of the first series of 60 vehicles began in April 1943. Fifty-two of these were built using new Panzer IV Ausf. G chassis and the remaining 8 from rebuilt Ausf. E and F chassis. Survivors, about half, were rebuilt beginning in December 1943; they were mostly rebuilt to 2nd series standards.


Production restarted in December 1943 of another 60 vehicles, using only new Ausf. H chassis, and continued until March 1944. The Sturmpanzer's baptism in combat at the Battle of Kursk proved that the driver's compartment was too lightly armored and it was reinforced. The gunner's hatch was removed and a ventilator fan was fitted, much to the relief of the crew. Internally sprung, steel-rimmed road wheels replaced the front two rubber-rimmed road wheels in an effort to reduce the stress on the forward suspension that was only partially successful.[6]


Production of the 3rd series ran from March to June 1944 with few changes from the second series. The Fahrersehklappe 80 was replaced by periscopes and the lighter StuH 43/1 was used.


The superstructure was redesigned in early 1944 for the fourth series, which used the chassis and HL120TRM112 engine of the Ausf. J, and was in production between June 1944 and March 1945. It featured a redesigned gun collar, as well as a general reduction in height of the superstructure. This redesign also introduced a ball mount in the front superstructure for a MG 34 machine gun with 600 rounds. The vehicle commander's position was modified to use the cupola of the Sturmgeschütz III Ausf. G, which could mount a machine gun for anti-aircraft defense.[5]
