    Not being a pro at all, just building some paper stuff for fun from time to time. Here a couple of 1:35 (T-30 and LT vz.38) and a couple of 1:50 (T-50 and P-26/40).

  6. I haven't found an appropriate thread where to put some interesting rare stuff related to WW2 development, be it industrial one or makeshift field modifications. Let's start with two things. The first one is a relatively recently found rarity from Swedish archives - a drawing of ČKD/BMM V8H-Sv tank. The drawing and a letter was found by WoT enthusiasts in Swedish archives in 2014 (the original announcement and the drawing source is here). The drawing is from a message dated 8th September 1941. One of the reasons why this drawing was not known before may be that the Czech archives

  13. At the behest of @Lord_James, this shall be the thread for general discussion of conventional passive metallic armor. Whether it's steel, titanium, magnesium, exotic laminates of all three, this is the thread for it. In answer to your earlier question, Lord_James, relatively small amounts of boron, in steels that have the appropriate levels of carbon, form intergranular barriers that dramatically slow the diffusion of carbon out of the austenite crystals during quenching. Long story short, this means that the depth of material that can be effectively hardened is much greater.

  16. So here's a question: is it better, without using interleaving or whatever, to have a few big road wheels or lots of little ones in terms of MMP? Here I'm going to ignore things like travel and have no spacing between the roadwheels. For a 5m track contact length, 40t vehicle with the other specs kept the same (track width 0.6m, track pitch 0.15m), you find that ground pressure rises quickly and then tails off as the size of the road wheels decreases. This rapidly leads into diminishing returns: 25 axles with 20cm roadwheels gets you an MMP of 95KPa, 50 and 10cm road wheels gets yo

  17. Some of the French 40s and 50s prototypes had pneumatic roadwheels, and I wonder if that was influence from the German 'expertise' they agglomerated post war. They did after all, also build some interleaved suspensions at this time - as well as desperately tried to get the HL 230 family to work to spec.

  18. Ajax turret would be too big and heavy for an IFV. 1.7m turret ring vs 1.4m for WCSP. It's also Lance-based and LMUK and Rheinmetall fell out because of the original WCSP turret failure.

  20. By all accounts the turret did work in the end and the battlefield trials for WCSP were going well. However with all the delays and cost overruns it simply became untenable to continue. I would say "politically risky" would refer to the optics of giving LMUK more money to continue a "failed" programme on another platform. ---------------------------------------------------------------------------- --------------------------------------------------------------------------------------------- Scottish Conservative leader standing on a Hawkei at Thales in Glasgow.

    UAV thread

    Tu-300 Korshun was in development in 1980s, first UAV build in 1990 and first flight taking place in 1991. It is Soviet UAV, but used by Russian forces because of timeline. Most likely yes, Chechnya was probably place of use. IMO during first Chechen war.

  24. Idk about IJA, but the practice has become a lot more common with the JGSDF. TKG is the most common way to refer the main cannon of armored vehicles. Basically TanK Gun. Usually it's just the XXmmTKG, but I've also seen the Type 10 cannon called 10TKG to differentiate it from the 120mmTKG of the Type 90. AFV's themselves on the otherhand really only receive this style of abbreviation from the Ministry of Defense rather than the JGSDF. ie: 90TK, 74TK, 89FV, 11CVR, 16MCV. https://www.mod.go.jp/gsdf/equipment/ve/index.html This nomenclature is frequently

  26. Already before WW2 Czechoslovak industry rutinely produced heavy extremely thick armoured cast pieces, especially observation cupolas and firing posts for the fortifications. To my knowledge at least three companies were supplying them in hundreds (Steel works in Vítkovice, Třinec and Škoda in Plzeň). They had a lot of experience from working on armoured parts for Austro-Hungarian fortresses and navy (basically all heavy machinery of A-H Empire was enherited by Czechoslovakia). The mass-produced armoured cupolas for Czechoslovak interwar fortiffication had 150-300 mm thickness (pe

  31. Basic History State of PVO before MiG-25 During the middle part of the 1950s, the PVO (Soviet air defense forces) were poorly equipped to deal with future threats. The majority of its interceptors consisted of aircraft such as the MiG-15, MiG-17, MiG-19, and Yak-25. These aircraft possessed sufficient performance to take on American bombers such as the B-29 and B-50, and were at least marginally capable of intercepting jets like the B-47 or B-52. However, they were horribly inadequate against coming bombers, such as the B-58 Hustler (which first flew in 1956). The arrival of Mach 2

  35. These designs seem to stray from the usual good practices of tank building. Bulky, tall and with little space for suspension. Armour on the "cannon" seems equal to that of a c2(IFV?). How is that justified?
