JS 7 Heavy Tank
 
Does anyone have information on the JS 7? I have only been able to find half a dozen photos on the web and the two dimensional line drawing. I do have a 3d CAD file that was graciously provided by another tanker - but I would really enjoy more photos or information for reference material.
Now if I could just purchase a big 3-D printer....
Thanks for you help

lol....make a is3, it has the late kv1 road wheels, it is 10 feet longer than a kv1......simple build imo...you can even use kv1 tracks......the is3 was designed to fight the king tiger....It will be one of my next builds.....

After reading this article about the King Tiger's flaws, I'm beginning to think the Soviet Union could have stopped their tank development after the IS-2.

Nice article Chuck. Was aware of the many severe mechanical problems and overall unreliability, but had not heard about the serious flaws in armor. Amazing how so many flock to the KT as if it was THE ultimate tank. With all the problems Germany had at that late
stage of the war, it's very doubtful that the E-100 would have had any effect at all, other than a mobile pillbox or roadblock like the JT.
Thanks for posting.

Unless I am not seeing this correctly, those road wheel look a lot like Tiger II road wheels? Just sayin.

RE: JS 7 Heavy Tank
 
From all I have read on the JS series...have to agree that the series should have ended with the JS-2. The JS-3 was so mechanically bad, that it was all Russia could do to have them running for the big 1945 Berlin parade. Those that were issued, rarely made it out of the motor pool. Those that were sold to Egypt were used very sparingly and only seen running by IDF crews after capture in Israel. The T-10, which was supposed to replace the JS-3 had terrible wheel bearing and road wheel design problems among other turret-crew operational issues and nothing after that ever became standard issue.

The JS-7 is a very nice looking tank, but as indicated, working space in the turret was a major issue, and then carrying only 30 rounds.[:'(]...I went through that in a day with my M-46, but we had 70 rounds as basic load and my 90mm was more accurate and had a much higher ROF than any 130mm. .

In spite of all, I am very convinced that our M-48 was designed after the JS-3, after the initial scare it threw into the allied forces when it was shown in the famous 1945 parade.

I would also love to build a t44......just get a t55 and a profile kv85 turret.....a very cool 1946 tank....

pattoncommander 10-06-2012 04:19 PM

RE: JS 7 Heavy Tank
 
That was a cool looking tank, but don't think many were issued. It was sort of a Russian M-47....stop gap from M-46 to M-48.

He is not the "World of tanks boy", am the voice inside the back of tsull's head telling him what to build. MUAHAHAHAHA! However, i would prefer to build a JS-4, or JS-3, because of the sprockets. IS-7 WOULD be shredded by an E-100. This may be off topic, but hey we are having fun right?

RE: JS 7 Heavy Tank
 
I actually like the M-47 very much. I like the large turret bustle. The realiability of the German tanks realy makes the whole comparison mute. The Russians had design issues as well as the German. nobody builds reliability and function as well as the good old USA.

pattoncommander 10-07-2012 12:33 PM

RE: JS 7 Heavy Tank
 
I always like the 47...its a neat design, BUT terribly flawed. The bustle box was great for stowage but being that it sat over the engine, you had to be carefull what was kept in it. Canvas items would dry rot if not taken out to air. The ammo stowage was totally assinine and M-13 range finder was less than worthless, but the M-47 had very good maneuverabilty and was relatively fast. I wish someone would put of out a good 1;16 model. The chassis of the 26 would do, but the turret and back deck would have to be totally scratch made.

Panther G 10-09-2012 04:30 PM

RE: JS 7 Heavy Tank
 
Could you not use parts of the M-41 turret to make the M-47? The bustles look quite similar, as well as the general shape. I bet it could be done. I made a KV-85 turret out of a T-34/85 turret.

The M-41 turret is too small, welded construction and angular. The 47 was molded with mostly rounded features. The bustle box is also smaller and not nearly as deep. Basically a similar design but M-41 was a bit wider and squat where the 47 stood taller due to the range finder and newly designed 90mm recoil system.

Having written that, it could probably be used as a base. I used the T-34/85 turret for the Egyptian T-100. A good, firm base makes an easier job.

Everytime I see a photo of your T-100 I wish to heck I had built that.......it really looks great.

I have two T38-85s, I guess I could use the second one for a T-100 conversion, but then I would need something to oppose it.......like a Centurion. I'm not sure I want to get into a different war.........I'm not through with the tanks I wanna build from WWII yet.

Israel captured a bunch of them during the Yom Kippur War and there are a couple at Latrun. There is also a 122mm version. Both were a death trap for the crews as the huge turret had very little armor and a nice, slow, flat target. If you want to build one, I have conversion sequence photos if that would help. It's a neat looking tank and everyone is amazed at the long gun tube. NOT a tank you'd want for urban combat. or in a wooded area.[:'(] Opposing tanks would also be M-51 and Magach M-48A5s.

I use mine for an IDF Target...has a high volume smoker with one hole plugged and a tube leading into the turret. Triggered by a micro switch to activate when the gun is over the light. I also have a photo of the T-100 with the original crew.
