Comments anyone?

I smacked the living hell out of these ships and they are all still afloat with very little damage. The fire seems to indicate I am dropping incindiaries on them [8|]
Anyone think this is too little damage?
Too much?
Just right?

UNLEASH THE HOUNDS!!!!

It's definitely a change from old PacWar. 1000 pounders were the great ship killers then.

I guess we'll have to look up the historical ship-killing scenarios and the deck armor stats.

[Moquia]

Its '44. Didn't the allies have AP bombs now?

[moses]

I'm sure you have FOG turned off correct??

[doomonyou]

I would say that a GP 1000 would do between 2-5 sys with 0 flooding and 1-3 fire points per hit up to a maximum of 50% sys (representing the explosives local penetrations of the deck armor but failure to get deep in the ship and wreck the hell out of it).

But certainly a dozen straight hits from 1000 lb GP would work over a BB pretty well, probably wiping out most of its AA capability possibly damaging mail turrets, causing fires on the top decks where those penetrations occur as well as structural shock damage to support members and such.

[MadDawg]

They probably need that armour to stand up to the uber-PT boats [;)] Hehe, in all seriousness though, here is what the Yamato and Musashi took to sink them according to Conways Fighting Ships...

"Musashi took between 10-19 torps and 17 bombs whilst Yamato took 9-13 torps and 6 bombs. Their armour was designed to give immunity against a 1t bomb dropped from 15,000 feet and 18" shells out to 22,000-33,000 yards. "

My take is that it seems these bombs are trashing the guns and the upper decks, but not penetrating the around to do damage inside (system damage - thus slowing speed). Looking at the info above for the Yamato and Musashi at least this damage probably sounds close to right (I would have thought 5-10 system) as it was the torps that sunk them, but i dont know much about the other ships.

Totally agree on this one. 24 hits on the Yamato convinced me 100%. I like to see the BB with 24000 lbs exploding on his deck with only 4% system damage and still dry feet[&:]

[mdiehl]

Not nearly enough sys damage and there ought to be more flot damage. Enough bomb hits along side will cause flooding damage and more flooding will be required to put out fires and to counterflood.

As an added note Conways did not list "what it took" to sink Yamato and Musashi. Only that which hit Yamato and Musashi. Yamato was doomed by the second bomb to strike her... a 1000 pounder that started an uncontrollable fire in a secondary magazine that was designed not sufficiently isolated from her mains. She had another uncontrollable fire aft that was the source of the underwater detonation. She also turned turtle from torpedo hits. She was, in essence, sunk three times: once by a single bomb forward, once by multiple hits aft, and a third time by torps. The torps put her underwater before the inevitable magazine explosions could occur.

[Wilhammer]

On near misses, many jap ships had incidents with severe damage from near misses - they had flaws in armor production and design.

The Chitose, for example, was badly damaged by a near miss, caused by plates warping and breaking welds and bolts.

It is said in post mortem analysis ( I forget the book) that the Yamato and Musashi likley suffered crippling near miss damage to its hull.

------------------

The world's navies all saw value in near hull misses - water does not compress and the exposive displacement results in an overpressure 'bubble' that is rather large and packing a lot of force that magnifies greatly the force on the hull.

Makes sense - torpedoes are not armor piercing, and they only hit at 30-50 knots, and they were one of the most feared naval weapons in all of history - the problem with bombs is that it is hard enough to get a hit, let alone plan a near miss.

But, they dropped a lot of bombs around Y and M, and so did you - I agree, the damage seems low.

[MadDawg]

Actually, conways book states that these ships were sunk by th above hits. It also states that the ships were designed to take a hit from a 1000lb bomb dropped from 15,000 feet.

Im not saying that this isnt wrong, but I wouldnt like to see the penetration figures screwed with lightly as overall the game feels about right. I would guess the combat is based on details such as explosive content, warhaed type, armor, etc and thus its not easy just to change the values of a 1000lb bomb without effecting other weapons (providing they are indeed not powerful enough)

The problem I see is that the Kongo class started out as Battle Crusiers and had some armor added. But, 9 1000lb bomb hits failed to penetrate the deck armor. Even with the Yamato, some of the 1000 lb bombs actually dropped on her penetrated the deck armor.
