France-Somua SAu-40.png

The Somua SAu 40 is a French tier 4 tank destroyer.

A proposed tank destroyer on the basis of the Somua S35. Existed only in blueprints.

Contrary to what the ingame description says, prototypes of the SAu 40 were actually built and at least one fought during the Battle of France.

The SAu 40, unlike it predecessor the Renault UE 57, is a slow moving warehouse that will take some effort to get used to. Once upgraded, it can equip an able 75 mm long-barreled gun that will take care of any foes up to its tier level, or a very powerful 105 mm howitzer able to destroy or cripple any higher tier tank that it may face, so using it before moving on to the next tier can be a rewarding experience. The SAu 40's frontal armor is not very good, even by Tier 4 standards, but the most glaring weakness is the small turret (also known as "The Tumor") on top, where it can be easily penetrated.

The Somua SAu 40 leads to the S 35 CA.

Historical Info

Somua Sau-40 derived from the S35 medium tank chasis
In 1935 France started the development of the new self propelled gun \ tank destroyer vehicle. Two companies responded with proposals. Societé d'Outillage Mécanique et d'Usinage d'Artillerie (SOMUA) started work on a project that was to become the SOMUA SAu 40, and Atelier de Construction de Rueil (ARL)began developing its ARL 39V prototype.

Unlike the ARL V39, which was based on the BDR G1B tank, SOMUA derived the SAu 40 from the very promising S35 cavalry tank that proved to be the best tank in the French arsenal at the beginning of World War 2. The SOMUA SAu 40 prototype was to be finished and presented to the army in 1937. Unfortunately, since it shared the main gun with competing ARL V39, it had to wait for a full year for the both primary and secondary armament to be mounted. Main armament was to be the 75 mm APX gun, a modification of the mle. 1292 de Casemate gun originally developed for fortifications. The gun un had a semi-automatic breech, automatic shell rammer, and a very odd and unusual feature: it could be retracted inside the hull to decrease the vehicle's length. Secondary armament consisted of a 7.5 mm machine gun placed in a small turret on the roof, similar to the competing ARL project. The 75 mm gun APX 1929 gun was to have a traverse arc of 7 degrees to the left and 7.6 to the right with an excellent elevation arc from -10 to 30 degrees. Maximum effective range was to be 2000 m, with an ammunition capacity of 102 rounds. The sights were quite advanced for its time, and they offered 4x magnification, with a field of view of 125 degrees.

With tensions running high in Europe just prior to the outbreak of World War 2, France was desperate for any kind of modern armor, and the SOMUA SAu 40 was ordered into series production. An order for a total of 36 vehicles was placed. By 1 May 1940, 72 vehicles had been ordered, but only the prototype was armed with the 75 mm gun. The production vehicles were instead armed with the powerful 47 mm SA 37 anti-tank gun as tank destroyers. It is known that the prototype SAu 40 fought during the Battle for France in June 1940, probably along with a few production vehicles. The fall of France in June 1940 brought an end to all further development.
