I realized that I put 3" deck armor on the BB, too high for any conceivable battle distance. Shaving it down to 2.5" saves 400t displacement.

Why would you want that many TTs, or any for that matter, on a BB? By the time you close to torpedo range you've defeated the purpose of the BB, to hit hard from far away. I understand this is a "concept ship", but still. IMO it's a bad idea.

In fairness - he did say it was a bad idea right in the thread.

It's a quaint idea - but if you were to build it, I'd dump the big guns for more armor or, perhaps, anti-cruiser guns.  You're not looking to shoot up battleships on the way in to torpedo range, you're looking to keep the enemy's screening elements from torpedoing you first.

Somehow that ship put me in mind of the late WW1 "large light cruisers". :)

I think the concept might work if she is reduced in size a bit, such a large torpedo loadout can if nothing else be usefull to disrupt enemy torpedo attacks on her before they get into range to launch their own torpedos.

Somehow I recall that some navy had proposed a torpedo battleship at some point, but I honestly can't think of who or when this was proposed.

Actually the USN did, around WWI. Battleship size, hardly any armor (4" turtledeck, no  belt) 4x14" and a zillion (32) 6" gun. Too lazy to look up Friedmann.

The design idea was inspired by battleship designs with 15"+ (i.e. inpenetrable) belt armor. This ship is supposed to take punishment, get close, and launch fishes at the enemy battleline. Won't do the job better than 20 DDs, though.

Thing is, though, given torpedo hit rates, and given that, by my understanding, tubes take a couple of minutes to reload, most of those super-armored ships aren't going to be much more impressed by those than they would be by gunfire.

Well, the ship can get close to improve hit chances. Then torpedoes are generally unimpressed by belt armor, and will cause some flooding. This ship can launch like 22 torpedoes (side ones with gyro settings, and after those torpedoes passed the ship, the bow ones, then disengage).

Still, better to get 22-30 destroyers, as the survivors would have more torpedoes to launch than one monstre ship.

Torpedo hit rates are basic trigonometry.
