Russian armored vehicle developments follow lines developed to support the "Deep Battle" concepts outlined in the writings of generals Triandfilov and Tukhachevskiy. They are:

Heavy tanks to support infantry in breakthrough operations

Heavy tanks require sufficient armor to resist defensive fire, and the firepower to engage and destroy fortified positions. The capability to engage multiple targets is desirable but not necessary.

Frontal armor of at least 30mm is required, while side and top armor of 10mm is sufficient.

A turret-mounted 76mm howitzer is sufficient for main armament. Two secondary turrets mounting 45mm guns are desirable to destroy machinegun nests as well as enemy tanks. Each gun has coaxial a 7.62mm machinegun, and a machinegun firing to the rear is also required.

Cross-country speed should be adequate to support an infantry advance. Road speed should be sufficient to travel from a railhead to the battlefield in a timely manner.

These requirements are fulfilled by two models. The first is the 45-ton T-30T heavy tank with a 76.2mm howitzer in the main turret, 2 45mm guns in secondary turrets, and 4 7.62mm machineguns. Frontal armor is 30mm, and side and top armor is 10mm. The T-30T is powered by a 500HP petrol engine giving a road speed of 30 kph and it carries fuel sufficient for 150km. The T-30T has a crew of 10. The T-30T carried 60 76.2mm HE rounds, 100 rounds for each 45mm guns, and 2000 rounds for each machinegun.

The second is the T-29 30-ton heavy tank with a 76.2mm howitzer in the main turret and 2 7.62mm machineguns in secondary turrets. Frontal armor is 40mm and side armor is 30mm. Top armor is 10mm.
The T-29 is powered by a 200hp diesel engine giving a road speed of 30kph and the T-29 carries fuel sufficient for 200km. The T-29 has a crew of 4. The T-29 carries 60 main gun rounds and 2000 rounds for each machinegun.

Cavalry tanks to exploit breakthroughs

The main characteristic of the cavalry tank is operational mobility. A road speed of 50 kph is desirable, and fuel capacity should be sufficient for 250km. Weight should be limited to 12 tons. A single 45mm gun with a 7.62mm machinegun coaxial and another machinegun in the hull is sufficient armament. Frontal armor of 25mm is sufficient.

The KT-30 fulfills this requirement. This 12-ton tank is powered by a 200hp petrol engine giving a road speed of 50 kph, with fuel sufficient for 300 km. The KT-30 has a 45mm gun in a single turret with a 7.62mm machinegun coaxial and another in the hull. Frontal armor is 35mm, with side armor of 20mm and top armor of 10mm. The KT-30 has a crew of 3. There are 70 rounds for the main gun and 2000 rounds for each machinegun.

Armored cars for reconnaissance

The BA-10 is a 6-wheeled vehicle weighing 3 tons. It is powered by a 50hp petrol engine, giving a road speed of 85kph and a range of 400km. Its cross-country mobility is limited on all but firm ground. It carries a single turret-mounted 12.7mm machinegun, and is protected by 6mm armor. It carries a crew of 3.

On Russian vehicles, platoon and company commanders have vehicles with a radio. The exception is the armored car, with a radio carried by each to facilitate reporting.

What about the T-26 what duty ,if any , will it perform?

No pictures?

Tanks are fairly useful for the Soviets due to the large open spaces. There is space for them to be used effectively and try to break through enemy lines. Other countries have little use for tanks. They don't perform well in mountainous terrain and so would not be built in large numbers by Italy or Nordmark for example. Then again, who is this large Russian tank force(and the massive army) pointing at?

I'm just waiting until I can build this;

Other countries have little use for tanks.

Unless attacking Russia which has large open spaces.

The only vehicle now in series production are the armored cars.

The T-29 is in low-rate initial production, sufficient to equip 2 Tank Regiments (plus spares, 210 vehicles total), for evaluating the maintaince requirements and to exercise emerging tactical concepts.

The T-30T is still being evaluated, and has been criticized for excessive cost, weight, and mechanical complexity. The "Land battleship" concept, while intellectually attractive, may not yet be feasible.

The KT-30 is also being evaluated, and criticisms of it revolve mostly around the feasibility of supporting and maintaining tank forces into the enemy's operational rear.

Historically, it seems VERY early to introduce fully-tracked APCs. Also, you might want to check the T-30, it looks like it has more cannon in the hull than you really want.

I assume the T-30 is a BT-5 type tank while the T-35 is similar to the T-34?

The T-30 is indeed similar to the BT-5/7, and the T-35 is a step up, with a 57mm gun and thicker armor, but still bit less capable than a T-34, which is another 8-10 tons heavier.

What looks like the extra cannon in the hull of the T-30 is the number of rounds stored in the turret.

And for the BRT-35, I couldn't see how to do a half-tracked design, so I went with fully tracked, but for WesWorld purposes we could treat it as a halftrack with a roof.

Quoted

Calibre (mm) # in Hull # in Turret Rounds (hull)
Cannon/Gun 1 45.00 20.00 1.00 50

That "20.0" looks like it's number of weapons, but if you say it isn't that's OK. Didn't want you wasting weight and space on 20 45mm guns in the hull.

Agree on not having seen a way to do half-tracks, but it's also WAY early for personnel carriers with roofs, those don't start appearing until the 1950s.

Any chance of some selective editing to make it easier to read? Getting rid of all the water performance stuff is a good start.

On the designs themselves, you'll probably want some more leeway for the suspension and transmission. What if a bunch of fat people sit in the BTR?

One other thing to be careful of with TankSharp that I've found: the program doesn't check to see if turrets are wider than the top of the hull, nor if the turret is wide enough at the top for a hatch. I've had to modify a couple of designs to fix problems with the sides of the turret overhanging the sides of the chassis, and where the turret top wasn't wide enough to put a hatch for someone to look out of.

In regard of the 57mm gun; why a 57mm when so far every one in the world is agreeing a 45 to 50mm range is good enough to do the work?

Also I have to agree with the roof in vehicles. No combat experience so far that shows the need for a roof. A tracked vehicle could be explained by using a modified hull of a tank as the chassis.

A couple of reality checks are all that are needed to keep Tanksharp in check. Or write in your own additions to the spreadsheet.

The process of tank design;
Calibre of gun - > size of turret -> width of hull -> length of hull (about twice width)

The roof would be pretty good for keeping water and snow out.

Still I doubt it will be armored. No reason for it, at least yet.

The newest gun in Atlantean service is the 57mm gun, introduced slightly sooner than the Russian weapon and for similar reasons that the Germans considered using a 50mm gun for their Panzer III's, in WW they are using the 50mm gun.

As for APC's the British, without combat experience, noted that the Bren gun carrier and its variants offered little protection for its occupants above the level of their shoulders.

As Hrolfs pointed out before its more an issue of cost not so much the concept of a fully enclosed shell to protect the troops beit from the elements or from enemy fire. Half tracks are much cheaper to produce.

exactly my point. Historically the open top vehicles were produced due to being cheaper to build even when it was proved they exposed the troopers to enemy fire. But the Russian decision to go tracked could be explained by using tank hulls as the basis of the Russian APC's.
