法系四级自行火炮“索玛S40”发展历史

  Yuri Pasholok posted another bit of info on the French vehicles, that we will see in the game. This time, it’s the Somua S40. By April 1939, the requirements for the modernization of the Somua S35 cavalry tank were laid down. The vehicle, that was to be based on them, was proposed to be mass-produced from October 1940. The requirements mentioned an overhaul of the hull and the suspension, but other changes were connected with the planned production of the CAM 2 (Somua SAu 40) self-propelled gun, which was 3 tons heavier than the S35.

  Yuri又发布了一篇关于法国新车的文章。这次是索玛S40。1939年4月,现代化S35巡洋(?不确定)坦克的计划出炉。而基于这个计划的车辆将于1940年的10月开始量产。其中有个要求是彻底大改车体和悬挂,但是这些改动与另一个CAM2(索玛 SAu 40)自行火炮有关,此车比S35重3吨。

  By the end of 1939, a prototype of the tank, recieving the factory designation of AC 5 (later recieving the name Somua S40), was made. Apart from the improved suspension, the vehicle also had a modified hull, based on the model used in the development of the SAu 40 SPG, as well as in the building of a 20 ton medium tank for the G1 program. One more new thing was the engine with its power improved to 220 hp at 2000 RPM (at 2200 RPM, the power actually peaked to 230 hp). The tank would weigh 20 tons and the engine would give it a rather good power-to-weight ratio of 11,5 hp/t, which is 1,5 hp/t more than the one of Somua S35. Its maximum speed was increased to 45 km/h.

  39年年末,坦克的原型车被造出,并且获得了AC 5的工厂代号(之后又改成索玛S40).除了更换了加强型悬挂以外意外,本车还有一个基于SAu 40自行火炮的改进车体,这个车体也用在了为G1计划设计的坦克。另外一个进步就是引擎可以在2000转的时候输出220马力(2200转下实际上输出有230马力)。坦克总共有20吨,所以功重比有11.5马力/吨,比索玛S35多1.5马力/吨。急速可以达到45km/h。

  As was written in an earlier article, the first 80 Somua S40 tanks were supposed to be equipped with APX 1 CE turrets (the same ones Somua S35 used). Nevertheless, even the first prototype was also tested not only with a new, boxy turret mount mockup, but also with the new ARL 2C turret mockup (welded instead of cast). By the way, not only a mockup was made of that turret, a real metal prototype was built as well (same goes for the hull). The first S40 hull was built in January 1940 in the Creusot plant, by April it was two more and by May, yet 5 more were assembled. As such, the plan to start the mass-production by July 1940 was completely realistical. However, because of the German invasion, it was all over as early as mid-June 1940.

  在之前的文章中也提到过,前80辆索玛S40讲装备APX 1 CE炮塔(和索玛S35用的是一样的)。不管怎么样,原型车至装了一个新的木质模型在上面,但是也有配套的ARL 2C炮塔(焊接的,不是铸造的)。顺带一提,炮塔不止有木质模型,也有一个金属制的原型造出来了(也放在车体上了)。第一个S40车体于40年1月于克勒索工厂制造出来,4月又造了几个,5月之后至少有5个被制造出来。至此,40年开始大规模生产的计划也成真了。但是,因为德国人的入侵,到6月中旬生产便完全停止了。

  This is the Somua S40 with S35 (APX 1 CE) turret, the first 80 tanks were supposed to look like this:

  这个是装有S35炮塔(APX 1 CE)的索玛S40,前80辆的S40应该看起来是这样的:
