King tiger turret armour

[chuckfourth]

The front armour of the King tiger turret armour is wrong. it has a slope and shoud be 19 not 18. Assuming these are porsche not henchel turrets of course, and using
real thicknes/cos(angle) = notional thickness

The Tiger II front turret was 180mm sloped at 9 degrees. I cant get that to be more than 182-183mm, which, converted to centimeters and rounded off, will only give an armour thickness of 18 in SP terms.

Could you explain how you get it to be 19 instead?

We've used a specialized calculator for this for years and I get the same result Claus does ( 182mm ) = 18cm (rounded down). To round up to 19 you need 185mm and you don't get 185mm on 180mm of armour until the slope reaches 13 degrees.

Hi Don,CBO
Well I should have checked this further, Tarriffs site has from memory (its currently down) 180 @ 81 (19) degrees, but interestingly this site
http://www.wwiivehicles.com/germany/tanks-heavy/pzkpfw-vi-b.asp
quotes amongst other thicknesses,
185@80° ie 20 degrees
with rounding up the latter figures give you a value of 20.
Best Regards Chuck.

A right angle has 90°, not 100°.
So 81° means 9° and not 19°, 80° means 10° not 20°.

Hi Popski
Jesus if thats the state of my brain I hate to think what my arteries are like.
The 185 at 10 degrees does still round up to 19 though, maybe a late war "improvement". or just an error dont know.
Best Regards Chuck.

All data based on the Henschel turret

http://www.onwar.com/tanks/germany/data/tiger2.htm

Turret 180mm@81° = ( 182mm )


http://www.wwiitanks.co.uk/

185mm@9°(187.0mm)Henschel


http://www.wwiivehicles.com/germany/tanks-heavy/pzkpfw-vi-b.asp

Turret Front 180@9° = ( 182mm )from "Encyclopedia of German Tanks of World War Two, Peter Chamberlain and Hilary Doyle, 1999 "

Turret Front 180mm = ( 180mm )from "Panzer Truppen The Complete Guide to the Creation and Combat Employment of Germany's Tank Force 1943-1945, Thomas L. Jentz, 1996 "

Turret Front 185@80° = ( 188mm) from "German Tanks of World War II, Dr. S. Hart & Dr. R. Hart, 1998 "



There will always be discrepacies like this. When these five quotes are totaled ( 919 ) and averaged ( /5 ) the result is 183.8 and that's 18 in game terms . That's what we have and that's what it stays.

Such discrapancies can usually be explained by differences in the way thickness and angle are measured and possibly small differencies in plate thickness between different batches of armour.

A detailed British report on a captured Tiger II reported 180mm at 10 degrees for the turret front while a less detailed British intelligence report gave 185mm at 10 degrees. Data from German sources seems to give 180mm at 9 or 10 degrees.
