Re: Wet Thrust/Full Steam Playtest

Here's some stuff from Conway's on pre-dreadnought armour:

The Fujis and their cousins the Royal Sovereigns had compound armour, ie
a
steel face on a wrought iron backing.
The other Japanese predreads (except Mikasa) and their cousins the
Majestics
had Nickel Steel armour.
Mikasa had Krupp cemented armour.

The Majestic-derived Japanese ships had a different armour layout to the
Fujis- although all 6 ships had the armour deck at the level of the top
of
the belt, the later ships had the edge of the deck slopingdown to meet
the
_lower_ edge of the belt, effectively making a second differently angled
belt inside the true belt.

On the effectiveness of different types of armour:
HMS Centurion (2nd class Battleship): belt 12" compound
HMS Renown (2nd class Battleship): belt 8" nickel steel _but giving
equivalent protection_

HMS Canopus (1st class Battleship ("close to being 2nd class"): belt 6"
Krupp Cemented "equivalent to 8" of Harvey"

It appears from this that the conversion is approximately:
3" Krupp = 4" Harvey/Nickel Steel = 6" compound

I vaguely recall "Devil at the Helm" giving credit of 1" of iron for
each 6"
of timber backing.

Ihope this is of some use
