dont forget das flugzeug
i think they are too easily spotted at night by the watch crew in SH3. In mid to late war, generally the first indication that an airplane had you dead to rights was the bright Leigh light beaming down on you, followed seconds later by a barrage of depth charges or bombs or rockets from which there was often no escape.
quite a ruthless foe really
piercing the night with radar, you cant see, and cant detect well even with the often faulty detectors...
it sees you though, from many miles away.
it dives in - engines idling. You cant hear it over the wind and waves yet still it comes down in the dark.
then in the last seconds, the light illuminates. and if the intense 50,000,000 candlepower light shined down on a German U-boat, the bombardier toggled a spread of bombs or depth charges.
from that little U-boat all you could do was hope against hope and often times that burst of adrenalin, that moment of fear and panic... that was the last thing you ever experienced in this world.
