An Analysis of the devastationwrought by U-boats during World War Two.

A post-second world war analysis of U-boat activity records some 4409 attacks on shipping. Subsequent analysis of this information reveals the following details;
n.b an attack does not imply the use of a single torpedo or shell.
-Description of incidents;
-2919 ships shunk - 14,232,747 ton - 66.2 % of all attacks
-32 Ships damaged beyond repair - 193,748 ton - 0.7 %of all attacks
-5 Ships Taken as prize - 10,018 ton - 0.1 % of all attacks
-401* Damaged - 2,707,398 ton - 9.1% of all attacks
-103 "Missed", attacks on identified targets with no result - 0 ton - 2.3% of all attacks
-949 Attacks where details are unable to be verified - 0 ton - 21.5% of all attacks

*Of the 401 ships damaged, 101 of them (708,712 tons), were later sunk.

In total the allies lost 14,436,513 tons of shipping to the U-boats, this represents 68% of all the shipping lost by the allies due to enemy action (total 21,194,00 tons, Churchill's History of the Second World War Vol 2).

Thus we can see from the above figures that the U-boat was a devastatingly effective weapon.

Analysis By Weapon Type.
- 3521 torpedos attacks - 2408 Sunk - 24 Damaged Beyond repair - 312 Damaged
- 319 torpedos & gun fire - 191 Sunk - 1 Damaged Beyond repair - 11 Damage
- 60 FAT torpedos - 22 Sunk - 1 Damaged Beyond repair - 13 Damage
- 259 GNAT Torpedo - 49 Sunk -5 Damaged Beyond repair -18 Damage
- 20 LUT Torpedo - 3 Sunk - 1 Damaged Beyond repair - 3 Damage
- 215 Gunfire - 158 Sunk - 0 Damaged Beyond repair - 16 Damage
- 4 Gunfire & Ramming - 3 Sunk - 0 Damaged Beyond repair - 0 Damage
- 7 Gunfire & Scuttling - 6 Sunk - 0 Damaged Beyond repair - 1 Damage
- 94 Mines - 66 Sunk - 0 Damaged Beyond repair - 27 Damage
- 5 Ramming - 3 Sunk - 0 Damaged Beyond repair - 0 Damage
- 10 Scuttling - 10 Sunk - 0 Damaged Beyond repair - 0 Damage

The most disappointing weapon would appear to be the acoustic homing torpedo (GNAT=German Navy Acoustic Torpedo, also known as the G7s, T5 and code named Zaunk├┬Ânig) it had a sinking success rate of about 19%. This was heralded as the "destroyer buster", it should have been a very successful weapon, with the U-boat commander only having to fire it in the general direction of the intended target. It is likely that this low strike rate is due primarily to the effectiveness of the allied countermeasures, in particular the use of the British FOXER and Canadian CAT, these noise boxes were towed along behind ships when in the dangerous waters.


The UBoats not only use torpedos or/and deck gun for sinking the ships but also ramming http://forums.ubi.com/images/smilies/88.gif and mines http://forums.ubi.com/images/smilies/784.gif , http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif I dont know what it means scuttling is it that the UBoats force the crew to leave there ships and them they sunk the ship by open a hole without torp or deck gun http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif,it whould be great to have mines laying, of course wolfs packs,milk cows etc so DEV. team how about start on that so that we can finaly have the complet game (that whould make it the perfect sim game http://forums.ubi.com/images/smilies/25.gif) http://forums.ubi.com/images/smilies/11.gif http://forums.ubi.com/images/smilies/11.gif.

I certenly don't know it (by any proof) but I suspect "scuttling" was consisting of a boarding action (protected by deck and/or flak guns) by the Uboat crew (not all merchants was armed, some was even without handguns) and technically severely damage the ship to sink her.

Scuttling would be that the crew of the ship would deliberately sink their own ship.

At the end of WWI the German Navy virtually scuttled their entire grand fleet rather than hand it over to the British

I think scuttling was usually done with explosives although you could open the bilges and let the water in?

Thats right, and they scuttled them around the entrances into scappa flow to try and block the british ships in! Those "blockships" are still there today if you go visit scapa. http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif
But they are not in the game, LOL Its like in the game, the british decided to raise the wrecks so as to give U boats easy access to scapa, http://forums.ubi.com/groupee_common/emoticons/icon_mad.gif ... oh then in the 1950s they put them back of course http://forums.ubi.com/images/smilies/cry.gif

I think the 'scuttling' in the above table refers to u-boat crews boarding other ships and placing charges. I know of a couple cases where they did this to save torpedos (the crews would often fall out of the boats doing it too http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif )
