nice design!

Its not to shabby but my only consern would be the torpedo defence, but for 1927 its very realistic. I would also tend to ditch the CT armor but that is a personal preferance. Its a very nice design and I wouldn't mind one of these baby's in my fleet. Very well balanced.

I'd pick Melampus

Other specs are quite equal, but Melampus is a better sea boat and can take a lot more damage:


Shellfire needed to sink: 54,826 lbs / 24,869 Kg = 32.5 x 15.0 " / 381 mm shells

Torpedoes needed to sink: 8.1


As opposed to:

Shellfire needed to sink: 33618 lbs = 22.1 x 14.5-inch shells

Torpedoes needed to sink: 4.8

well

I think the Melampus being 6000/7000 tons heavier than the other two designs should be able to take more punishment but the El Pais and Indian design for their size pack quite a punch none the less. being of lesser size you'd be able to build more of em.

Portugal is no option

PORTUGAL can hardly compare to the other two designs due to her low speed. A difference of 4 knots can not be ignored. It offers a great strategical advantage allowing to cover a much larger area and is also of some help when it comes to a gun fight (tactical situation). With a 4kn difference the faster ship can easily decide when and how if forced to fight.

The costs necessary to get those 4kn are really big but still the indian ship (being also much newer) doesn´t compare too bad when it comes down to armor. She only lacks in gunfire compared to a 12 gun broadside but given that she surely uses a more modern gun I have no doubt the real difference in firepower is much smaller.

So of the three ships posted here and knowing that the indian ship cannot be build heavier I´d take the indian ship. I think the Doctor got the maximum out of her displcement.....

Cheers,
