I’ve already received quite a few questions, so now I will try my best to reply to all of them. Some of your questions (like for example one regarding the AMX30) were quite a bit away from my field of expertise so I’m afraid I couldn’t cover all of them. Here’s an excerpt of the most interesting questions: Q: Why did Ferdinand have two loaders? A: This was done mostly because they could afford the space in the big case-mate. Two loaders could be also faster in accessing ammo stored further away from the gun and this was probably done also because there were some plans to install a 22cm captured french howitzer, which meant some very heavy ammunition. Spielberger’s “Special Panzer Variants”, “Tiger & its variants” and “Heavy jagdpanzer” covers the subject on different aspects pretty well. Q: What was the gun depression in the different Panther and Tiger variants? A: Panther standard turret is rated at -8 +20 degrees by Spielberger and same was expected for the Schmaulturm. Data for the 88mm L/71 was expected to be -8 +15 degrees. Tiger with 88mm L/56 was also -8 +15 degrees, while I couldn’t find any data on the variant with the 88mm L/71. Q: Maus and E-100 has loader for 128mm gun and for 75mm gun, but could 75mm loader help to load 128mm shells and vice versa to reduce loading time? A: While in theory the 75mm loader could help with the main gun I’m not 100% sure it was something very ergonomically viable as he seated quite a bit in front and to the right of the 12,8cm breech with no easy access to the ammo stored on the other side of the turret. Maus II turret project was actually aimed at fixing this with a larger turret ring and different layout. Q: how Germans repaired repaired dents and holes left from enemy shells? A: This is not my field of expertise, but in most cases replacing pierced armor plates was the most widely used solution. Tanks were also overhauled for maintenance once a certain amount of wear had set in, meaning that any damaged part would be replaced in the factory or repair shop. Q: Do you know any information why 7,5cm*konisch was abandoned? A: All Gerlich guns used tungsten round, which represented something progressively harder to acquire for WWII Germany, making it vulnerable to ammunition shortages. Although later in the war steel core rounds were developed those were less effective due to lower muzzle velocity and given that the gun had a pretty short barrel life the much more economical 75mm L/70 was preferred for similar performance. Q: What kind of german auto-loader guns would seem likely to make it into the new german td line for world of tanks ? A: Historically there were planned tank loaders from 75mm to 128mm, with a few referrals on a 15cm assisted load as well. Those were both drum and cassette loaders, depending on the caliber, while lighter cannons were adapted for auto-loader by Luftwaffe. Basically if WG wanted we could have auto loaders for all tiers, starting from 37mm* and 50mm up to 128 and 150mm. Spielberger’s “Panther & its variants” mentions most tank autoloaders but don’t expect to find much detail on the subject. Q: In World of Tanks, it’s easy to catch a German tank on fire because the transmission/engine/gearbox (not sure which one it is) is in the front. Was there an advantage to putting that device in the front as opposed to the middle/back? A: Frontal transmission was considered to be better for tractive power in rough terrain and track wear although it had disadvantages in making the tank taller and requiring more internal space in general. Still, it was considered technically superior and the decision to go for a rear transmission/gearbox in the E-Series was still pretty reluctant. Ernst Kniepkamp was the best expert on the matter as he constantly worked on transmission project during WWII, eventually becoming head of Wa Pruef 6. Q: I am interested in the technical side of the evolution of tank suspensions. *Panzer III is rather interesting, since it went through several different types. The Porsche design with longitudinally mounted torsion bar is also quite neat. Do you have access to hard technical data and/or nice blueprints? A: Spielberger’s “Special Panzer Variants” has some good pics of Porsche and E-series suspensions, Panther, Panzer III and Panzer IV also by Spielberger’s respective books while Tigers are covered by Jentz & Doyle’s “Germany’s Tiger tanks” series. I could post some pics but scanning that much from the authors is not nice (or legal) so I suggest you just take a look at the mentioned titles. Q: Do you have any technical data on German tank guns: mounts, stabilization, breech design, etc? A: I’m afraid that’s a bit over my field of expertise. Jentz, Doyle and Spielberger treated the subject only on the performance side and I cannot suggest much on the subject. A good start could be “Panzerabwehrkanonen 1916-1977″ if you can read german or the “Encyclopaedia of WWII german weapons”. Ian Hogg also wrote good stuff on the subject but it’s pretty old and hard to find IIRC. Q: Is there any chance you could do an article exploring the original evolution of German tanks in WW1 and the immediate postwar period, including the A7V and its brethren, the K-Wagen, the LK-I and II and the Swedish developments which followed, and the Sturmpanzerwagen Oberschlesien? A: I do have some material about WWI tanks but I’m not 100% sure about its quality. I could do an article on the subject but don’t expect anything too obscure unlike WWII projects. Q:Do you have any data on the Schützenpanzer Büffel? A: AFAIK the tank you mention is a modeler kitbash. A simple rule of thumb is that if it’s not mentioned by Jentz, Doyle or Spielberger it’s likely to be a fake. Authors like Hahn and Sowodny can be also used but have to be taken with a pinch of salt as in some instances they tend to do dubious reconstructions (Kleintiger is a prime example). Q:*Lexikon-der-wehrmacht.de says there were planes to rearm a tiger 1 with a 12,8cm PAK L/66 named ‘’Tiger-Jäger’’. Do you know if it’s fake? A: I think someone mistranslated Jentz, the only Tiger-based project with the 12,8cm PAK L/66 is a Krupp proposal for improving firepower on the Jagdtiger, which included a case-mate extension and severely reduced gun traverse both horizontally and vertically. Q: Do you platoon? A: I usually platoon with my GF, if you wanna join me you’re welcome but beware it will be Continue reading →
