yes it happens quite often especialy to big ships. All ships besides small vessels have left/right side compartments and can flip over one side. It happens very often to battleships with this mod. They will flip over and sometimes stay afloat downunder.

Its looking good so far, I like it :up:
we only need to mod the water to look like this:

According to what I read someplace (dunno where) the USN studied our losses to the U-boats and determined that most ships were sunk due to loss of stability, not flooding per se. It sounds like your mod does this if you see more ships list, then sink, or go down at the bow or stern, then sink...

I've read a few accounts of ships that did not have longitudinal bulkheads (divided down the middle - that usually was only done with large warships) which still capsized. Some of them even rolled over in the direction away from the torpedo hit. Apparently the water rushing in forced the ship to heel away from the impact side, and then it kept going that way.

Also in those Japanese convoy documents there are a few accounts of ships carrying steel which sank within thirty seconds of being torpedoed.:dead:

unfortunaly there are not many innert cargo types. you can differ between freight, fuel, ammo and empty.

in my mod ammo and fuel will in most cases cause a catastrophic explosion that will instantly destroy the ship and it will sink quite fast. When the fuel cargo does not ignite it will take the longest to flood because fuel is floating on water and it takes long time to replace fuel with water. Freight type cargo will flood faster then empty but be also less important for floatability of entire vessel bacause you can put more water in an empty ship then in one loaded with freight.

I have a question....

What happens when warships engage each other or planes bomb, or torpedo warships and freighters when using this mod..

I imagine they find it difficult to sink anything with shells.. or maybe not... anyone tested it...

WernerSobe 07-06-07 07:32 PM

shells are not affected. The battles between ships are lasting just about the same. But killed ships will of course sink slower. Same for the Deckgun. You will need about the same amount of shells to sink a ship because i didnt changed hitpoints.

You can however also sink ships with the deckgun by flooding. Give it like 10-15 shells in each compartment. wait for a while and see if it started flooding. If it does, chances are good that it will sink on its own once it took enough water. I recomend the real deckgun mod with 25 seconds reload time. It fits best to the slow flooding.

Very nice so far!

Hello Werner,

I'm no tweaking expert, but my files are tweaked by myself to a great extend, so to merge more mods together without them biting eachother. So I went ahead and downloaded your mod. I use the Die Slowly mod by Redwine and the New effects (not yet released, it's a test version) by Leovampire. I would need to tweak your mod right in. I looked at the torpedo_us.zon file, and to my surprise I've seen you reduced the min/max EF values. I thought they were the explosive power of the torpedo, but than again, I'm by no means an expert in this.
Furthermore in the zones.cfg I see you made the flooding a very long proces, which is good IMO.
Resume, what exactly does the min/max EF value do in relation tt the torpedo. I am assuming T1=MK10, T2=MK14, T3=MK16?, T4=MK18, T5=MK23, T6= MK27

Please advice,

Reg

Werner, you are de man :up::up:

Hope this works with TMaru. One of my tactics when I get the opportunity is to hide under a crippled ship to avoid destroyers, with your mod it looks like I will be able to do this more often:rock:

tater 07-07-07 06:56 AM

BTW, this mod des NOT interfere with the hardcore torpedo mod.

Jace11 07-07-07 07:38 AM

yup thats all in the torpedo sim file, so even better...

Yes I like this mod too...

New questions:

Can you disable a ship easily.. Will a direct hit on the engine room stop a ship in the water still? Or will she only stop when that compartment is completely flooded...(which now takes much longer)?

What mods is the zones.cfg combined with... The aircraft section looks different... any changes to sub flodding also??

tater 07-07-07 08:35 AM

I tested a little last night with this mod on. I hit a tanker (large) and she kept steaming. The convoy as a whole did the "mill about" nonsense, but for my second spread (aft tubes) I got a speed of 6 knots on her (quick set up, not sure how accurate, but 2 fish hit, one was a dud).

The escort held me down, then a DD showed up (a subhunter patrol near Truk) to help him. When they finally left 30 DCs or so later, the tanker was dead in the water listing to starboard and settling by the stern. After a couple hours I got the ship destroyed mnote, but she was still wallowing, she eventually capsized. VERY cool.

:up:

Yeah, quick question: does this mod also affect YOUR submarine?

ReallyDedPoet 07-07-07 09:28 AM

Nice work, have been reading some of the posts here.

Will give it a go:up:

Here are some screenies from a quick test in the convoy attack mission from the submarine school..

I got opposite results to tater, the instant my torpedoes hit I got the target destroyed message.. weird!!

Nippon was hit at stern by only one torp and I got the message instantly!!! Even though it took her 15 minutes to go down..

The Biyo rolled onto her side and went down nicely.

When the first Nippon did go down, as she went down stern first there was a massive splinter explosion which I thought was a bit odd. But on the whole much improved.

I hit another Nippon and she started to go down stern first slowly, then about 5 minutes later her back broke and the bow went down quickly while the stern settled and sank slowly... nice... lots of fires etc..
