1934 BB design
--------------------------------------------------------------------------------
First of all I must state that I have no part in this ongoing Sim but wish to observe and give some alternative opinions. If anyone wishes me to leave then please say so.

As an outsider i think that the treaty limits should be kept to, but not stringently because what are limits for if you break them?

The 15"/50 gun is the principle weapon of most BB's i have created tis design has 14" guns bored out from the 15" gun to give a 14"/54 weapon. I have stated the guns as 14" but have left 300t in misc. weight to balance this-sound ok?
On the whole she is armoured like an Elephant: a result of my obligatory quad turrets.

What's the threat this ship is intended to face? Small marine mammals that eat the eggs? ;)

A juggernaut, no doubt about it. And good speed too. Would it happen to have a ram? Might be a feasable tactic with this thing. The only hope is to put many holes in the unarmored bow below the waterline to slow it down, and jam a turret with a non-penetrating hit. Fortunately, this last one only has to happen twice. Then close and destroy. A 16" belt will not repel Russian 356mm or 381mm rounds at 18000m and 21000m respectively.

Well supposing my country is strictly neutral in this scenario it needs protection from marauding navies. A fleet of ships based on this would be unnerving especially with my country operating 2 ships together at all times.

Another version has 4 turrets but 16" turret armour.



I have no part in the sim.
