PANZER Insight's video: WW2 StuG III Ausf A - B - C - D - E - Sturmgesch tz III - footage part 1

The role of a self-propelled gun came from combat experiences in World War I and from Von Manstein’s “Sturmartillerie” concept. During the German offensives on the Allied front, infantry lacked artillery support against fortifications in places out-ranged by their heavy artillery behind the lines. A need for a mobile artillery piece was necessary to keep up with the German infantry and fight enemy fortifications with a direct-fire assault role. On June 15, 1936, Daimler-Benz AG was ordered to develop a support vehicle mounting the 75 mm howitzer as its armament in a casemate structure with a traverse of 25 degrees. The vehicle was to provide full protection for its crew and be no taller than an average soldier. Daimler-Benz repurposed the chassis and running gear of their Panzer III design for the role. These new vehicles were named the Sturmgeschütz III, and the finished designs were sent to Alkett for prototype production and five were produced in 1937. These prototypes were made of mild steel and had the 75 mm StuK 37 L/24 cannon, an adaption of the original 75 mm KwK 37 cannon on the Panzer IV. This gun would be featured on the StuG III variants Ausf. A to Ausf. E. The StuG III entered production from January 1940 to the end of the war on April 1945 due to the many upgrades done on the vehicle to increase serviceability and its low cost. At about a total production of 11,300 StuG III and its variants, the StuG III design was the most produced armoured fighting vehicle in German service. Only 36 Ausf.As were produced by Daimler-Benz AG between January and May 1940. The first were delivered in September 1939 and the whole series completed in April 1940. The last six were based on the Panzer III Ausf.G chassis. However, due to numerous production faults, only four batteries were sent in France by May 1940. The Ausf.B was produced by Alkett and saw a much larger production, between June 1940 and May 1941. They were nearly identical to the Ausf.A, if not for the slightly larger tracks. Standard roadwheels were interlocked with external 520x95mm ruberrized roadwheels and both were interchangeable. The early 10-speed transmission, which proved troublesome, was replaced by a 6-speed one. To reduce chances of the tracks being thrown off during tight turns, the forward return rollers were re-positioned even further forward. The Ausf.C was nearly identical to previous versions and was only produced for a single month, in April 1941, with 50 vehicles coming out of the factory. The C had the main gunner’s forward view port eliminated and replaced by a relocated periscope in the front left of the casemate. The Ausf.D was virtually identical, only receiving an on-board intercom. 150 were delivered between May and September 1941. It was simply an upgrade of the C on the production line. ■ Support me on my Patreon patreon.com/Panzerpicture ■ Store: https://teespring.com/stores/panzerpicture-2 ■ Information obtained from several sites. ■ Wikipedia ■ tanks-encyclopedia ■ the.shadock.free.fr/Surviving_Panzers ■ preservedtanks ■ pantser.net ■ the.shadock.free.fr/Tanks_in_France ■ Some music is from the YouTube Audio Library. ■ Music used: EpidemicSound.com ■ Music used: Cloister of Redemption by Jens Kiilstofte machinimasound.com/music/cloister-of-redemption Dystopia by Per Kiilstofte machinimasound.com/music/dystopia End Game by Per Kiilstofte machinimasound.com/music/end-game Rallying the Defense by Per Kiilstofte machinimasound.com/music/rallying-the-defense Battle of Kings by Per Kiilstofte (Machinimasound) machinimasound.com/music/battle-of-kings/ The Land of the Wizard by Per Kiilstofte (Machinimasound) | machinimasound.com/music/the-land-of-the-wizard/ Licensed under Creative Commons Attribution 4.0 International (http://creativecommons.org/licenses/by/4.0/) Copyright fair use notice All media used in this video is used for the purpose of education under the terms of fair use.
