Calculating armour values.

[MarkSheppard]

IS-7 Specs

Weight around 68 tons

130mm S-70 Main Gun (stored 30 shells)

4x 14.5mm MG

Semi-autoloader(6-8 rounds per minute) (It was not a real autoloader, more like power-assisted loading as used on various SPHs. Hence it still needed loader to place ammo on a tray.)

~1,000 horsepower diesel engine


Armor (got the data from www.tank-net.org a long time ago, and then converted it into SP format)

420mm Effective Hull Front
150mm Effective Hull Sides
150mm Effective Hull Rear
300mm Effective Turret Front
200mm Effective Turret Sides
200mm Effective Turret Rear

EDIT: found some info in my Steel Panthers Editing FoldeR:


HULL
Front: 210mm @ 60
Side: 100 to 150mm @ 0
Rear: 60 to 100mm @ 55
Floor: 20mm
Top: 30mm?

TURRET
Front: 210mm @ 45
Side: ~150mm @ 40
Rear: ~100mm @ 15 to 65
Top: 30mm?

EDIT: here is the open office formula I use to calculate armor values:

=(B3/(COS(C3*0.017453293)))/10

C3=Slope of Armor
B3=Thickness of Armor in MM

It then outputs armor equivalent thickness in CM, which is what SPCAMO uses.
