But how does the Type 21/22 E/3M look in those pictures?

 

Armament:

1 107mm L/56 Gun

1 7.92mm Coxial

1 13.2mm AA MG

2 Grenade Launcher Pods

 

Armor: (Top to bottom)

Frontal, 180 +36+26, 95, 105, 56

Sides, 65 +~10, 60, 40 (and rear third)

Rear, 40, 40, 20

 

Line of sight, the additional armor over the turret face allows an effective thickness of ~280 millimeters. 

Upper frontal is laid back 67*'s from the vertical for a line of sight thickness of 240 millimeters

Lower frontal is laid back 48*'s from the vertical for a line of sight thickness of ~155 millimeters

Lower frontal lowest section is laid back 67*'s from the vertical for a line of sight thickness of ~140 millimeters.

Turret sides get some 10mm thick stowage bins.

 

Speed:

56 kph maximum

41.4 tons

700 hp engine

 

personally its too british and russian to be japanese. should keep the front hull simple, and either keep the turret rounded or boxy with slopes. that turret looks like someone mated the back of a centurion 7/1 and the front of a T-90.

UDES 15/16 wip
From what I can guess from the blueprints, this one carries 4 8-round magazines from which it uses the 2 mounted on the back of the gun and the other 2 for reload, it would make for a very complicated autoloader system. But hey, I'd really like to see peoples' reaction if a 16-round 105mm (?) autoloader gets added to the game, with 32 total in ammorack and ~70 sec reload ~5 sec between rounds (not actually going to happen).

Looks great so far, i like how you get a completely different perspective when you get to see something in 3d. Also we are probably going to see the udes 15/16 in the game someday... just not in the way id like.

Udes 15/16

Spoiler

A WWII Swedish prototype Light tank, featuring a 16 round (2 magazines 8 rounds each) autoloading 105mm gun and a hydraulic suspension for extra gun elevation and depression. I really liked the design of this vehicle, it was just way in front of and very anorthodox for it's time. Overall it looks great, but it's highly complicated autoloading mechanism (wich the designers probably did not even bother to start thinking how it would work) would cause problems, both in the manufacturing and in the reliability of this tank in a fight. That aside, with it's high maneuverability and devastating gun it would be able to take out multiple enemy units in one run. This model includes turret side skirts and some heat shielding.

From the schematics, I could tell that the autoloader of this tank worked with magazines which are mounted on the side at the back of the gun. Each autoloader has space for 8 105mm rounds and some sort of a system that pushes the rounds at the autoloader mechanism. Apart from that I have no idea how the rest of the autoloarer is supposed to work, only that it should push the shell in the gun and then extract the empty case from the top of the gun just like a T90.

This tank should be able to have 10° of gun depression and 6° elevation, but it also features a hydraulic suspension (just like the S-tank) which would add to these numbers.

It's not Japanese... I renamed it to "Kataphra III", meaning "cataphract", or at least, that's what I got from google translate... It doesn't show up anymore though... Maybe it's Kataphrakt? And Kataphra is plural?

 

Yea, I've already started revising the frontal hull.

That's basically the concept behind the original turret... The next one also follows approximately the same concept, though it takes a more "Russian" approach to it's turret. As the upper section is laid back 78*'s from the vertical, with a raw thickness of 56mm, and an effective of over 280mm against KE. At an angle able to shatter any WW2 era tank round, save for HEAT, but that can't pen it at all. Some modern HEAT rounds can, but with some difficulty, especially at a non optimal angle. 

The turret, including it's spaced armor schemes in model #2, reaches up to ~350mm effective armor, or 240mm + 40mm for raw thickness values.

 

"The Kataphra III’s turret was designed to protect against some of the largest guns even employed by an opposing army at the time. And thus, when taking into account the inability of the turret to retain its function upon impact, it was decided that existing armor protection was insufficient. Not only did it have to deflect as much kinetic energy as possible; in the zones where the needed shape was of a non optimal angle, major sections of spaced armor were added on top of incredible thickness. Such an armor protection, would prove to be highly effective against all kinds of kinetic penetrators-”

 

In other words, it’s armor protection on the turret has more than just a “few” bad impact angles to strike on, and when the armor will not lend itself to an optimal angle, is incredibly thick. Additionally, it's been built in such a manner, that the turret only has five primary sections. Four of which are the frontal arc. The rear one is welded together however.

 

It's 107mm L/56 gun is capable of imparting greater amounts of kinetic energy than the L7 Royal Ordinance, but suffers by comparison in characteristics such as being repaired, it's weight, size, rate of fire, and basic accuracy.

 

Able to pierce about 240mm of RHA at a distance of 100 meters (APCBC), with a muzzle velocity of around 920 m/s with a 22 kg projectile, it's a little overpowered for it's size.

Though if we compare with the 128mm, and employ the DeMarre calculation, it should put a hole through around ~265mm...

UDES 14 Alt 2

Spoiler

A WWII Swedish prototype Light tank, predecessor to Udes 15/16, similarly features an autoloading (I guess the mechanism would be like Amx-13's autoloader) 105mm gun and a hydraulic suspension.

This tank should be able to have 6° of gun depression and 30° elevation(wow), but it also features a hydraulic suspension which would add to these numbers.

The machinegun I used is the Kulsprutegevär m/1940, a quick google search yielded that it was used by the Swedish Army, and I liked the design, enough to include it. Not an actual historical detail, as far as my research is concerned.

A bit more rushed job than what I wanted.

Just checking but you do know that the udes tanks are early to mid 1970s designs right?

I was guessing around the time that S-tank was designed, so yes pretty close. If you are worrying about the modernisations, they are there partially because the models (from just early blueprints) would look plain without them and also because of the S-tank, if you look at the first prototype and then at the Strv 103, you can see how much different they are. I tried to replicate that in my models. About the Kulsprutegevär m/1940 that was a total miss, but I think it gives a nice touch, I'm tired of seeing Brownings.
