CV90's big brother incoming: 

Some of them even make it back to the helipad they flew off from.

Nobody's using turbines right? I didn't mention it in this thread yet, nor update the range calculator, but there's an 0.7 times modifier on range for turbines.

 

Is the Lone state of Texas even able to produce high heat reistant alloys for turbine vanes?

I've decided on a nickname for my vehicle: Brahman.

Just some updates: 

  • added sponsons 
  • reduced turret roof height by 6 inches 
  • increased barrel length to 32 calibers and breach counterweight (it is no longer "balanced", but I think I have a work around)
  • reduced upper front and roof plate thickness to 0.8 inches (20mm)
  • revised some geometry, to reduce weight (currently at 28.45 tons)

 

What would be a "good weight" for my engine? I have it currently modelled as 3.5 tons (3180 kg), including the liquid cooling and transmission. It's a 12 cylinder, 6.9 inch (175mm) bore by 7.1 inch (180mm) stroke, 1000hp engine based off the MB 838.

That sounds about right. A decent transmission will be 2000 kg or so

I was thinking more along the lines of a beefed up Sherman transmission, preferably the "high speed reverse transmission" (mid-way down the page)

But yeah, my components are too light, should be closer to 4 tons, the normal MB 838 is nearly 2 tons dry.

      IDF had kept about 100 Tiran-6/T-62s since 1973, and remain service until 1990s. 
       
      I wonder if there's any modification on Tiran-6, like changing the powerpack into 8V71T+XTG-411, adapting steering wheel. 
       
      I also heard that British ROF had produce a batch of 115mm barrel for IDF, while MECAR or NEXTER produced high-performance APFSDS for 115mm gun. Did IDF really use these barrels for original barrel replacement? 
       
      And about protection, did IDF put Blazer ERA on Tiran-6? Or they use more advanced APS like Trophy? 
       
      Thank you.

      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 were partially destroyed by floods in 2002. Anyway it is an export modification of the V-8-H tank accepted into Czechoslovak service as ST vz.39 but never produced due to the cancelation of all orders after Münich 1938 (for the same reason negotiations about licence production in Britain failed). Also later attempt to sell the tank to Romania failed due to BMM being fully busy with Wehrmacht priority orders. The negotiations with Sweden about licence production of V8H-Sv lasted till 1942, at least in May 1942 Swedish commission was present in Prague for negotiations. The tank differed compared to the base ST vz.39 in thicker armor with different front hull shape (armor 60 mm @ 30° on the hull front and also 60 mm on the turret; all sides were 40 mm thick). The tank was heavier (20 tons) and had the LT vz.38 style suspension with probably even larger wheels. The engine was still the same Praga NR V8 (240-250 Hp per source). The armament was unchanged with 47 mm Škoda A11 gun and two vz.37 HMG. The commander's cupola was of the simple small rotating type similar to those used on AH-IV-Sv tankettes. It is known that the Swedes officially asked to arm the tank with 75 mm gun, replace the engine with Volvo V12 and adding third HMG to the back of the turret. In the end the Swedes decided to prefer their own Strv/m42.

      The second is makeshift field modification found on Balkans. It appears Ustasha forces (and possibly some SS anti-partizan units) used several Italian M15/42 medium tanks with turrets from Pz.38(t). There are several photos of such hybrids but little more is known. On one photo it is possible to see Ustasha registration number U.O. 139.

      Few more photos of such hybrid.
       
      It appears that the source of all those photos to be found on the internet is this book, Armoured units of the Axis forces in southeastern Europe in WW2 by Dinko Predoevic.

      I was recently looking at the Japanese wikipedia page for the Chi-Ha tank, and it had this section on the name of the tank:

       
       
      I have never heard of such nomenclature, and obviously I don't have access to such documents since I don't live in Japan. There is no reference for this part, so can anyone confirm that they actually did use "MTK" etc.?

      70 years ago, January the 2nd, 1951. To the North of Seoul, in the mountains and hills near Go-yang-tong(高阳洞), British 1RUR dug in and fought against advancing PVA forces. 1RUR got a task force called Cooperforce to support, this is a tank unit from Royal Tank Regiment and Royal Artillery, equipped with Cromwell tanks. 
      When Matthrew Ridgeway assigned the order of withdraw in this afternoon, the US force covering British force's left flank quickly escaped from their sector, leaving the British were completed unawared and uncovered. 
      When the night falls, was cold and dark in the valley. 1RUR had to withdraw in the darkness. All of a sudden, a US spotter aircraft flew over the valley, drop some illumination flares upon the retreating convoy. 
      Fierce battle broke out when flares fall down, PVA firing from all directions, the cold valley became deadly kill zone. Some PVA soldiers put away their rifles, assaulting with hand grenades, satchel charges and Bangalore torpedoes. They even set up mortars on the hill, laying shells with direct fire. 
      200 British soldiers and artillerymen were killed or captured in one night. 1RUR's Battalion Commander Tony Blake was believed KIA. Cooperforce was completely knocked out, all 12 tanks were destroyed or captured by light infantry. Leader Ashley Cooper were also killed.
