Hi Guys,
just a little detail in the scene: The captain orders "both engines slow ahead" just before opening the tubes. So he doesen´t go with the tubes open at flank speed. From my point of view, it is not so unrealistic: The captain uses a moment where there are no escorts around and the moon is behind some clouds to reduce the distance to the target. So there is a good chance that nobody sees the speeding submarine. The attack itself is done at slow speed. Greetings, Stefan.

The U-Boats were little boats. Of course they were a bit more nimble than the larger American subs. The Type IX had comparable dive times and comparable size to the American submarines. When you're talking much less mass, you need less buoyancy to keep her up on the surface safely, which means less water to take on to get to neutral.
The crew is a much higher percentage of the weight of the submarine, so their positions within the boat influence the pitch angle much more than they would in a larger American boat. One thing you give up with larger size is nimbleness. But you gain the ability to take enough firepower to win a sub war. The Germans needed a lot more subs to have a chance. And they didn't have enough manpower to run the subs even if they had enough of them. That was a major part of their problem getting the Type XXI to war. Nobody could run them on a war footing and they couldn't spare the crews from active duty to train them.

Section VII : (b) When attacked at Night. Night attacks on U-boats are in the nature of things generally made in the vicinity of convoys. Whether the U-boat is attempting to attack on the surface or has been detected submerged the tactics may well be to surface as soon as possible and escape at high speed. (c) Asdics. Some of the limitations of the asdic are known to the enemy. It is realised that contact must necessarily be lost when running in to attack and sometimes as soon as the attacking vessel is committed U-boats increase to full speed and work their pumps if required. Many commanding officers endeavour to keep their boat bow or stern on to the attacking vessel in order to give the narrowest extent of target. The ping of transmission can be heard by hydrophones in a U-boat at greater range than that at which it is first possible to get an echo. When the A/S vessel is at close range the transmission can sometimes be heard aurally. (d) U-boats sometimes deliberately allow themselves to be sighted while other boats in the vicinity get away or attack without interference. |
