So what was the historical torpedo load for an IXD2?

[Ducimus]

This isnt about the ole torpedo reload bug, im just curious as to what the acutal historical data really is. I don't know why, it just suddenly peaked my curiosity.

Many sites list the IXD2 payload being 24 torpedo's. I think at least one site listed 26.
The core of this contension i think is exactly how many external deck stores did it really have? If 24 torpedos, then im guessing its 4 aft and 6 foward, or 2 aft 8 foward.. If 26 torpedos id guess 4 aft, 8 foward.

But what was it really? Like i said, most sites say 24, at least one that i cant find now says 26, but heres whats intresting. If you go here:
http://www.9teuflottille.de/site/lexikon/lexikon.html

You can D/L the plans for an IXD2 and a couple other boats. If the plane (top down) view is correct, your looking at 4 aft, 8 forward external canisters. Im thinking maybe the answer is both 24 and 26, cause a snorkel has to go somewhere and they probably took out two torpedo canisters to install it?

Good question Ducimus...I have checked the U-boat sites I use and they give the same numbers you are qouting (24 or 26)...however, when you go to this site:
http://www.uboatwar.net/IXD.htm

It gives the number as 22 :hmm:

It'll be kinda interesting to see what other info you receive as a result of this post :yep:

[Captain Nemo]

uboataces.com puts it as 24 see below:

Type IXD2 Weapons
Bow tubes: Four 21 inch
Stern tubes: Two 21 inch
Torpedo capacity: 24
Mines: None
Guns: 1 x 105mm cannon, 1 x 37mm Flak, 1 x 20mm Flak

I can give you guys a more definite answer by tonight.

I remember reading about a type IXD that was able to cram 27 torpedoes on board. It was in a report about the interrogation of some prisoners of the sub. I don't remember which one it was, but the report is somewhere on this page:

it mentions 24 in here ...

From uboatwar.net:
22xTorpedoes
Bow 4x21inch
Stern 2x21inch
or 44TMA (66TMB)

Lets all hope for a definitive answer soon :hmm:

Submarine IX D/2 have many modifications. Submarine can have from 19 to 28 torpedoes and intrnal storage (including tt) was 12-18. External torpedoes load was from 3 to 16.
Few boats was building in variant minelayer and have 6 torpedoes.
Submarine in cargo patrol in Japan have 2 torpedoes only (aft tt).

[Jmack]

These boats, designed in 1939-40, have been called IXD/41, IXD and my main source gives them as IX D1 and IX D2. The difference between D1 and D2 was mostly in engine layout and power. The D1 had teething troubles and the D2 boats had a more proven layout. (These%20boats,%20designed%20in%201939-40,%20have%20been%20called%20IXD/41,%20IXD%20and%20my%20main%20source%20gives%20the m%20as%20IX%20D1%20and%20IX%20D2.%20The%20differen ce%20between%20D1%20and%20D2%20was%20mostly%20in%2 0engine%20layout%20and%20power.%20The%20D1%20had%2 0teething%20troubles%20and%20the%20D2%20boats%20ha d%20a%20more%20proven%20layout.)

These were more than 500 tons heavier and almost 10 meters longer than the IXC/40. They were armed with 24 torpedoes in 6 tubes (4 at the bow and 2 at the stern) and had the secondary armament in the form of the Utof 105mm/45 deck gun with roughly 150 rounds of ammunition. (These%20were%20more%20than%20500%20tons%20heavier %20and%20almost%2010%20meters%20longer%20than%20th e%20IXC/40.%20They%20were%20armed%20with%2024%20torpedoes% 20in%206%20tubes%20%284%20at%20the%20bow%20and%202 %20at%20the%20stern%29%20and%20had%20the%20seconda ry%20armament%20in%20the%20form%20of%20the%20Utof% 20105mm/45%20deck%20gun%20with%20roughly%20150%20rounds%20 of%20ammunition.)

In 1943-44 the torpedo tubes were removed from the D1 boats (U-180 and U-195) and they converted for transport use. In their new role the could transport 252 tons of freight. (In%201943-44%20the%20torpedo%20tubes%20were%20removed%20from %20the%20D1%20boats%20%28U-180%20and%20U-195%29%20and%20they%20converted%20for%20transport% 20use.%20In%20their%20new%20role%20the%20could%20t ransport%20252%20tons%20of%20freight.)

[Jmack]

now .. looking at this i discover the type VIIF

These boats, designed in 1941, were primarily built as torpedo transports and were never fitted with the typical 88mm deck guns found on other VII type boats. They had 5 torpedo tubes (4 at the bow and 1 at the stern) and as attack boats they would carry 14 torpedoes but in their transport role they would have up to 39 torpedoes onboard. (These%20boats,%20designed%20in%201941,%20were%20p rimarily%20built%20as%20torpedo%20transports%20and %20were%20never%20fitted%20with%20the%20typical%20 88mm%20deck%20guns%20found%20on%20other%20VII%20ty pe%20boats.%20They%20had%205%20torpedo%20tubes%20% 284%20at%20the%20bow%20and%201%20at%20the%20stern% 29%20and%20as%20attack%20boats%20they%20would%20ca rry%2014%20torpedoes%20but%20in%20their%20transpor t%20role%20they%20would%20have%20up%20to%2039%20to rpedoes%20onboard.)

*GW DEV TEAM*

Two of them, U-1062 and U-1059, were sent to support the Monsun boats in the far East waters. They were the largest and heaviest type VII boats built. (Two%20of%20them,%20U-1062%20and%20U-1059,%20were%20sent%20to%20support%20the%20Monsun% 20boats%20in%20the%20far%20East%20waters.%20They%2 0were%20the%20largest%20and%20heaviest%20type%20VI I%20boats%20built.)

[Ducimus]

I thought about the VIIF before. I remember reading that the main torpedo transport storage area was acutally AFT of the control room. The boat couldn't use them. So technically speaking, the inclusion of that uboat is rather pointless. I've thought about "fudging" it and putting them forward, but it felt kinda cheesy.

edit:
Back on topic, yes i remember reading that prisoner interigation report on uboatarchieve.net. In specific i know the interrigatee said 26 torpedo's. If you d/l and look at the boat plans, you can count the cansiters. Again, i think the answer is BOTH. Orignally 26, but later two canisters were delelted for a snorkel installation, which would put the count to 24 torpedo's. Thats just a theory though.

[VonHelsching]

I think this might be the same case with the Typ II and how many torpedoes it would carry. Theoretically it was 6, but most war patrols were carried out with 5, since the only place available to put the 6th, it was above the hatch to the battery area, virtually blocking it, IIRC.

Maybe this is a similar case with the IXD/2. It's a big fat sub. If you really needed more torpedos there should ve been space to put them. It just probably wasn't practical for the "average" war patrol, whatever average means.

Actually I like the IXD/2 better than the IXB,C. Feels safer (isn't actually) and has more torps.

[Ducimus]

In SH3 the IXD2 has one major allure, and that is its fuel capacity. Can cruise ANYWHERE, and not have to be overly concerned with fuel consumption. Maximizing submerge time in order to save fuel sometimes gets really oldwith me, but often i have no choice if i expect to make it back to base. A hit in the fuel tanks in my opinion, is tantamount to death sentence if at 100% realism and/or no nearby milk cow avialable.

My only beef with it, is its a really large target.

OUCH!! That's got to hurt!:dead:

Did you take him down with you???

No, its the torpedo juice...The juice from the torpedoes... And its Seaman Hornsby...OINK OINK!!

OUCH!! That's got to hurt!:dead:

Acutally, the other escorts did. He was in their line of fire, and in trying to hit me, they blew him up. His exploding, i think is what destroyed what was left of the boat in that picture. I didnt have but like 5% H.I after the depth charginig, raming, and one or two shell hits.

And no, i didnt drink any fuel oil. Theres two captains on my boat. One's me, the others this fella named Morgan ;)
