STRIDSVOGN KW.III Ausf.M

INTRODUCTION

This is an Panzer 3 that has been put into Norwegian service post ww2, it is an Ausf.M Early Production. This vehicle to be added either as a part of a Norwegian subtree within the Swedish techtree or in an future Norwegian techtree.

HISTORY

The Pz.III came to Norway a little after the German invasion of Norway in April 1940, the Germans did not expect there to bee a need for heavier tanks, as Norway did not have any other than a couple armored trucks. Because of this the smaller and less powerful Pz.III and Stug.III were brought to Norway. During the occupation, the tanks Germany used here were sent to Germany and upgraded a number of times, and in a wide variety of variants and mixes, and when the war came to an end, the Germans surrendered all their vehicles to Norwegian and British/American forces that had fought in Norway. The British wanted to sabotage most of these vehicles, and among trying to blow up the barrels of the various tanks, they had driven over and destroyed a whole bunch of surrendered motorcycles. Most of these tanks were later on put in service in the Norwegian Army, and because of the British sabotage, the Norwegians worked on restoring these vehicles until 1948, before they were ready to be used. And because of the vehicles being damaged and parts having to be taken from here and there, those vehicles that already had been upgraded/mixed by the German army during the occupation, were even further mixed by the Norwegians during the restoration, with this vehicle potentially being one example. Then they were taken over by the army, the Panzerkampfwagen III were named and officially given the designation Stridsvogn KWIII, and the Sturmgeschütz III were given the designation Stormkanon KWIII. The majority of these tanks were put in service in so called “Airport Troops” to guard the various airports in the country.

The fate of the StuG.III are unfortunately lesser known, but thankfully the Pz.III is better documented, those remained in service until the mid/early 1950’s when they got replaced by the New M24 Chaffe tanks received tough the weapons aid programme, and lrgely replaced by 1953. After ended service those remaining Pz.III were either dug down and encased in concrete in defensive positions around some airfields in Norway, where they were used in a “Bunker” to shoot at invaders. Those were used until the 1960’s when the tanks were rendered obsolete. After this they were for some reason completely buried along with the bunker/fort they were integrated with, and almost forgotten until these people decided to save them and have them restored.

This Ausf.M/J hybrid was used at Trandum Camp east of Oslo, Norway, where the image is taken.

I have spent a lot of time, and have tried to identify all the Stridsvogn KWIII and Stormkanon KWIII that was used by the Norwegian army, that i have managed and been able to find pictures of. As none of the books mentioning them, has any sort of descriptions of their modifications or hybrid combinations, i’ve had to do this myselves, so there might be errors. If you see something, let me know!.

VEHICLE BREAKDOWN AND IDENTIFICATION

Hull and turret: Ausf.M Early Production
-Missing splash guard on the commander’s cupola, this was added on later production variants
-Missing mounting brackets on the turret for the schurzen spaced armor on the turret, something that were added in later production
-With the introduction of the Schürzen the vision ports in the turret hatches were dropped, this one still has them
-An easy way to rule out the Ausf.L is that Bosch headlights were mounted on the fenders with the Asuf.M model, as well as the tailplate was completely redesigned.
-The Cannon is of the Long L/60 50mm cannon, the last model to be produced with the L/42 cannon was the Ausf.J Early production.
-The Ausf.M was the first model to be introduced with the smoke grenades installed

Key details about this specific Ausf.M (Some might be Norwegian modifications etc)
-Lisence plate number: Unknown
-Add on amor/tracks lower frontal plate, 20mm RHA armor protection (wt stats)
-Add on amor/tracks lowest/under frontal plate, 20mm RHA armor protection (wt stats)
-Roadwheel on left fender front, 15mm structural armor (Wt stats)
-Roadwheel on left fender rear, 15mm structural armor (Wt stats)
-It’s fitted with an short L/42 50mm cannon wich was unusual for the Ausf.M as it was produced with the longer L/60 50mm cannon, indicating that this is an later modification where it has received the cannon from an Ausf.J Early Production and is highly likely an Norwegian post war modification
-20mm armor plate/spaced on mantlet.
-Seems to be missing the storage box on the rear of the turret, might be the open hatch that hides it.

ARMOR
Main Plate: 50 mm of face-hardened or rolled homogeneous armor on the hull and turret front.
Appliqué (Spaced) Plate: An additional 20 mm plate was mounted with an air gap in front of the driver’s superstructure and the gun mantlet.
Effective Thickness: This combination provided approximately 70 mm to 77 mm of effective protection against many light and medium Allied/Soviet anti-tank guns.
Side and Rear Protection
Hull/Turret Sides: 30 mm of rolled homogeneous armor.
Hull Rear: Varied between 30 mm and 50 mm depending on the specific section (upper/middle/lower).
Schürzen (Side Skirts): The Ausf.M was factory-fitted with 5 mm thin steel plates on the hull sides and 8 mm plates surrounding the turret.
Purpose: These were primarily intended to stop 14.5 mm rounds from Soviet anti-tank rifles, which were capable of penetrating the 30 mm side armor at close range. They also helped prematurely detonate High-Explosive (HE) and early HEAT rounds.
Secondary Components
Roof: 10 mm to 18 mm thick, providing minimal protection against air attacks or high-angle artillery.
Floor (Belly): 15 mm thick, designed to offer some resistance against anti-tank mines.
