Habsburgs - my 1912 battleships

[Borys]

Ahoj!
I forgot to post - these two ships are "2nd batch Juan de Austria" class.
Nothing fancy about them, with A-P-Q-X turrets.
The deck got minimaly thickened (1/3"), the CT got 2" more armour, the torpedos are of new type - 20", and the range extended (1500nm).

Ahoj!
I forgot to post - these two ships are "2nd batch Juan de Austria" class.
Nothing fancy about them, with A-P-Q-X turrets.

My guess would be APQY. Like Gangut ;D

[Borys]

Ahoj!
Thank you, I stand corrected. I simply NEVER remember the designation of the last turret - is it Z, or X, or Y.

Borys

[Sachmle]

For some reason unknown to me if there is only 1 turret aft it's the "Y" turret, but if there are 2 the on farthest aft is "Y" and the other is "X". "Q" is always amidships, fore most is always "A". None of it except the "A" really makes any sense to me anyway.

The only time it's EVER really made sense was Agincourt w/ the whole days of the week thing.

Ahoj!
There was thread on this on the battleships board not so long ago.

The idea is to use letters which are not confusing when you say them out loud, i.e. do not rhyme:
Ay
Bee
Pee (supposedly from "port") - rhymes with Bee, but there never was a ship with Bee and Pee on it;
Que
Why
Eks
