After testing of the hull was completed development of the project came to a halt due to problems with the ammo that were trying to develop for it. Of the 2 hulls that were made there were 3 plans, one became the chassis for an artillery, and the other became the test rig for the hydraulic suspension that would be used on the Stridsvagn 103. The third plan however was to mate the turret of a British Centurion Mk10 onto the completed hull of the Kranvagn and use that as a basis for future tank designs but nothing came of the plan.
Now, the Kranvagn hull historically has armor thickness of: 95mm upper hull, 145mm lower hull, 40mm side, 40mm rear… this is the 2c armor configuration and has the same effective armor as the IS-7 so that can’t work out at tier 8. I would say give it the 1b configuration which would be: 70mm upper plate, 120mm lower plate, 30mm side
The turret is the Mk10 but i can’t find any armor thickness for it anywhere so let’s use the Mk9 that we have in game. The gun would also be a 105mm and thanks to swedish documents you the weight would be about 37t.
So this would be the stats for it:
Tier: 8 HT
Weight: 34.68 tonn
Maximum speed: 45/18
Hull traverse: 30
Turret traverse: 37.54
Radio range: 780
Hull armor: 70*/30/30 (*70mm upper plate, 120mm lower plate
Turret armor: 152/88/88
Gun (revised): 105 mm Royal Ordinance L7A1
Aim Time: 2.5
