So what was the historical torpedo load for an IXD2?

Ducimus · 10-16-06, 08:31 PM

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:

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

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:

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).

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 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.

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.
