as you probably already know if you read this blog, Yuri Pasholok recently visited the armor museum in Thun (Switzerland). Another remarkable vehicle that he saw there was the Panzer 58 Swiss medium tank. Here's some info about it.
Yuri Pasholok最近访问了瑞士图恩(Thun)的装甲博物馆。他发现了一辆值得一看的车，就是瑞士的Panzer 58中型坦克。以下是一些介绍：
For numerous reasons (especially economical ones), Switzerland didn't have its own armored vehicles for a very long time, opting to purchase foreign vehicles instead. Switzerland is however now only known for its mountains and banks but also for its quality arms manufacturing industry (that includes not only guns and rifles), previously however there were no real indigenous Swiss tanks. There were attempts during and after the war to build indigenous armored vehicles (such as the Nahkampfkanone project) but it never really went anywhere, since it was much cheaper to buy the Centurions or the G-13 TD's than to develop a vehicle on their own.
This attitude changed in the 50's. It's no secret that Swiss arms companies (Oerlikon, Solothurn) actively cooperated with the Germans in WW2. This cooperation continued after the war and it started to include tanks as well. In 1953, an alliance of German companies (Porsche, Daimler-Benz, Zahnradfabrik and Ruhrstahl) participated in a project of a new tank for India. This was the 30 ton class Indien-Panzer that was to be produced in India by the Tata company. Swiss companies participated in the development of the Indien-Panzer as well. The project was ready in 1954 but the client refused it in the end. There was nothing wrong with the tank actually, but Tata was not able to actually produce it. After some deliberations, the Indians chose to simply buy the British Centurions instead.
But the project did not end there. In 1956, the Germans started the Europanzer project, which was based on the Indien-Panzer 30 ton tank and so it was that the Indien-Panzer evolution resulted with the AMX-30 and the Leopard 1.
The Swiss did not stay idle either. The Indien-Panzer project, not possible to be built in India, was not a problem for the advanced Swiss industry. By the time the Indien-Panzer was developed, the Swiss worked on their own medium tank, receiving the index KW.30 (Kampfwagen 30, 30 ton battle tank). It was developed by Eidgenoessische Konstruktionswerkstaette (EKW) in Thun - it was the principal Swiss military design bureau, dealing not only with armor but designing aircraft as well. The vehicle was supposed to be armed with an indigenous 90mm cannon (9cm Kanone 48) and the engine was to be German - Mercedes Benz Typ 837 (the same one as proposed for the Indien-Panzer).
此时瑞士人也并闲坐在一边。虽然印度坦克项目无法在印度生产，但对于更先进的瑞士企业来说，这不是问题。在德国人研发印度坦克时，瑞士人也在开发自己的中型坦克，他们接到了KW.30坦克(Kampfwagen 30，30吨战斗坦克)的项目指标。由位于图恩的EKW(Eidgenoessische Konstruktionswerkstaette，译注：直译大概是联邦制造业学会之类的)进行研发，这是瑞士军工的主要设计单位，不仅设计装甲车辆，还设计飞机。原本预期采用国产的90mm主炮(9cm Kanone 48)和一台德国产的发动机，即梅赛德斯奔驰Typ 837(和印度坦克项目相同)。
The prototype development was delayed and it was only ready in 1957, two years after the intended start of mass production. The early mock-up was created with 5 roadwheels, the same as Indien-Panzer.
The second prototype, after which the mass-produced vehicle was named, was armed with the British 20pdr gun (which was by the way license-manufactured in Switzerland as 8,4cm Panzerkanone 58). Instead of the coaxial MG, the vehicle received new 20mm Oerlikon gun (20 mm Panzerkanone 61) and the amount of roadwheels was increased to six. This is the prototype that was saved and remains in the Thun museum. After the trials, 10 pre-series vehicles were ordered, upgunned with the 105mm guns "10,5 cm Panzer Kanone 60" (a license-produced version of the British L7). These 10 pre-series vehicles were later modified to become the first Swiss mass-produced tank, the Panzer 61. 160 of those were made (this number includes the modified Panzer 58's), a rather large number for the neutral Switzerland.
第二辆原型车(之后的被称为量产型)装备了英国20磅炮(瑞士授权生产的型号是8.4cm Panzerkanone 58)。新的20mm厄利孔机关炮取代了同轴机枪，负重轮增加到六个。这辆原型车还保存在图恩博物馆。经过测试，订购了10辆预生产型，并将主炮升级为10.5cm Panzer Kanone 60型坦克炮(英国L7的授权生产型号)。后来这10辆预生产型后来经过改装成为了瑞士第一批大规模制造的坦克，也就是Panzer 61。Panzer 61共生产了160辆(这个数字包括改装后的Panzer 58)，对于中立国瑞士来说，这个数量已经很大了。
Design-wise Panzer 58 (and early post-war German tank projects) was heavily inspired by the American design school (roadwheels, support rollers, suspension configuration, cast hull and turret and other elements). The "traditional" German elements (interwoven suspension, welded hulls) seemed to have disappeared.
