Yamato's armor deck was immune to 1000 GP bombs in terms of direct penetration. However one of the suggestions i have forwarded to Matrix for WitP, if not UV, is that GP bombs need to be able to generate a much greater chance for Fire Level generation regardless of penetration or not.

Modeling this in would correct the "all or nothing" aspect of penetrating vs non penetrating hits, whether shell or bomb strikes. If generated in sufficient levels, Fire levels can cause SYS and weapons system damages or even a catastrophic event.

Yes, quite ugly for your boys Sonny. And by far the ugliest to date. (First of all our engagements where somebody's Surface Combat TF of multiple capable ships was sunk to a ship)

Oh, a little bit of intel for you, you hammered the Washington pretty d@mn good.

The penetrating critical hit was a 1000 pound AP. Here is the specific quote:
The second penetrates the port side of the aft Command station and explodes between the 155-mm gun magazine and main gun turret No. 3's upper powder magazine.
The explosion of the 155 magazine set off the No.3 main, and recent underwater photography indicates that the explosion spread through the No.2. main magazine.

I think the model needs to increase the system damage from GP. BBs were rather easy to render inoperable by GP ordnance even if sinking them required substantially greater effort. Musashi lost a main battery to a US bomb splinter that penetrated the gun barrel to the breach and detonated a shell that had just been loaded. The breach blast destroyed the elevating machinery rendering the turret inop.

No explosion occured aboard Yamato until after she had capsized which was caused by torpedoes. All your website verifies is that an explosion occured aboard Yamato which is already well known since it was photographed. Whether or not it was caused by fire or by the contents of the magazines upending cannot be asertained. The bomb mentioned in your example exploded above the armor deck.

Oh goodie! I lost 9 ships but I got to hammer the Washington pretty d@mn good. Seems worth it. I'll try it again (if my ships ever come back from Japan:( ).:D

You're not alone Sonny. I had a 3Ca,1Cl,6DD TF run into Soulblazer's Washington, South Dakota and one other BB with some CLAAs and loads of DDs at Lunga and lost every ship. What a slaughter, but I think I sent the Washington back to Pearl( somehow not a fair trade-off).

The bomb mentioned in your example exploded above the armor deck.
That's not a inference derivable from the TROM. In any case, even were it true, it simply shows that the design and layout of the armor was poor, since *one* bomb killed her by starting a fire, deep in her interior, in a critical magazine, where other flaws in her design (such as the failure to adequately isolate magazines) guaranteed her destruction -- or would have, had not the torps also killed her.

There were two explosions, by the way. One above water (that's the one in all the famous pictures) and a second one underwater. While the results of recent underwater photorecon cannot confirm that the fire in the 6" magazine led to the detonation of number 2 main, it almost certainly led to the detonation of number 3 main, based on the ship's design. All sources further agree on several key points:

1. The fire was started in the 155 upper mag by a 1000 lb bomb.
2. The fire was uncontrollable from the start and could not be contained -- much less extingusihed.
3. The 155 upper was not adequately isolated from other magazines as a matter of design.
4. The fire in the upper 6" mag is the best probable cause of the explosion of at least one and perhaps two main magazines.

In some ways, the results of the recent underwater photos indicate that Yamato's demise was similar to (but slower than) Hood's.

I actually felt sorry for Drex there. :)

I had JUST gotten the Colorado and South Dakota into port. Up to that time, the Washington had still been undergoing repairs in port, along with several other ships from the first battle of Lunga Point. If he had sent down that force eariler, with a battleship with it, would have really hurt. Instead, I surprised him.

All I can say is that the Washington is one SOB tough ship! She took THREE torpedo hits and a dozen shell hits and came out of the battle with sys of 61 and float of 82 with some minor fires (and she started the battle with 39 sys). Of course she's going back to Pearl now -- along with three CL's, two CLAA's, and four DD'. But I have two more battleships and plenty of destroyers coming. Still hurting for a CA, though.

And Drex still has the Yamato and Musashi. I still need to tread carefully.

You've stated nothing new here Mdiehl that i did not cover in the Why Dive Bombers Should cause Floatation damage thread. I suggest you re-read that since all you are obviously interested in is yet another rant against a Japanese design. Hardly a suprise from someone who neither plays or supports Uncommon Valor. The fact remains that Yamato surcombed to progressive flooding caused by torpedoes and suffered an internal explosion after she had completely turned turtle.
