    Look at these four pictures of four different U-Boats. Look at the hour glass shape of the forward superstructure. WHY DID THEY DO THAT? Ive been to two dozen sources and I see no mention of it. The subs are U-190. U-516, U-875, and finally U-883. I can tell you that U-190 was a type IXC/40. Who can dispel the mystery???Click image for larger version

      The big 'ocean' boats of the Type-9 design were notoriously slow to submerge. All that superstructure gave up its air slowly. The pinched superstructure was an effort to shorten the dive time.

        The big Type IX's, as David said, were very slow to dive. The Germans tried two solutions both of which helped only a little.

        First, they removed part of the forward deck to that pinched waist look. In German it's called "Scnelltauchdeck" which literally means "quick diving deck". I have also seen this referred to as a "Schnelltauchback" which means "quick diving upper deck".

        Secondly, looking at the first picture you can see that the vertical fairing of the top deck at the rear of the pinched area is actually angled back towards the stern. Once they got the bow submerged to that point the angled vertical portion acted as another "angled down" diving plane.

        If I ever do a German WWII sub it'll be a type IX with a Schelltauchdeck. Maybe the U805 - see picture

            Well I know you know what it is but did you know that it comes apart? looks like they removed the port side of it. I didnt know that you could do that. I thought that it was accessed from the inside. Otherwise it would seem like it would be fragile.

                It's the hull penetration for the radio aerial.

                          Hajen class sub Uttern built in 1958. The Swedes helpfully put abbreviations on the sail during this period. Uttern means "otter.". If you look carefully, you can barely make out the name on the bow.
