She's extremely well armored, though I might consider shaving the armor a little bit and putting on 3"-4" or so of end armor, to ward off flotation loss from lighter shells.

Looks like all of the 40mm mounts should be raised, not just 3 of them. Of course, only 6 mounts seem to have made it onto the drawing, so the other 6 could be at main deck level.

The fire of the 6" and 5" batteries will be overwhelming, which is exactly what you intend. I'd agree with Hrolf's suggestion of adding end armor. If she really is going to tangle with CLs and DDs at close ranges, she'll need it.

And that's a prodigious shell out of a 14". You're going to have great armor piercing capability with it.

And that's a prodigious shell out of a 14". You're going to have great armor piercing capability with it.

Along with probably horrendously short barrel life. Even the UK's heavy 14" projectiles for the KG V's only weighed 721 kg, as far as I know the record for a shell of this size. You might want to back off the weight to the same weight as the US is using in their 14" guns, if you're planning on sourcing the guns/shells in the US, that would still give you a very powerful gun.

Some additional thoughts:

I guess it's a personal preference, but I think 5" and 6" are close enough that they don't merit a two different calibers of secondaries. On rapid fire, either will ruin a destroyer or CL. She kind of reminds me of

Her belt sits very high in the hull, but the torpedo bulkhead is also very tall, so she should be well protected. Still, I'd be concerned if she ever had to fight at a light displacement. A diving shell (like PoW suffered against Bismarck) might be a concern.

The 10" barbette armor worries me. Even with her high belt, 10" seems a little vulnerable.

With that wide a stern with that shape, why not fit twin rudders? Maybe extend the hull form or centerline skeg to improve support for that long stern overhang?

She has a good distribution of firecontrol, both primary and secondary. Aesthetically, I like her tower bridge, single funnel and high mainmast. The latter being spaced well back from the funnel, balances her superstructure looks.

And she certainly has all the ingredients of a modern battleship. She'll be quite a flagship for the Hellenic Navy.

Big Rich

The 5" are more for AA than AS (probably a 5"/25 given the era) so the 6" is seen as necessary for extra punch. A split secondary is more in line with the times. The cats could interfere with the midships AA. There may be scope to shift but I can't have the stack take the wing off the plane as its launched.

Good comments on the stern Rich, it does look to be a little flat and wide.

I also have a version where the armour is thinned and the speed pushes 31 knots (higher freeboard) with the engines taking up the space left in the belt length but that doesn't seem as ballanced as this design.

Thanks,

Regards,
