          In fact, it was a fictional ship in a Japanese movie called Lorelei: The Witch of the Pacific Ocean, which featured a submarine that resembled the French Surcouf, which was intercepted by Nazi Germany and converted into a new type of submarine for the Japanese, the Japanese named it I-507 (伊-507)

            The Surcouf is in the background. Hold down the control key and zoom in and you will notice the name "Surcouf on the side of the hull on the left of the picture. Now , notice the darkened area just to the right of the name. That is a rotating panel attached to a torpedo mount that pivots and rotates out. Notice these next pictures of other French subs that use the same system.
            This rotatable torpedo launch structure is called "Trainable" torpedo launch structure.This torpedo firing structure was relatively common and distinctive on French WWII submarines, and was developed to allow submerged firing. However, I found that the two trainable torpedo launchers at the stern of the Surcouf could only fire torpedoes from the surface. Trainable torpedo launchers were also found in WWII submarines of other countries, such as the Orzel and Wilk submarine.

              Hi, guys, I have just bought the Surcouf plan from "ASSOCIATION DES AMIS DU MUSÉE NATIONAL DE LA MARINE​" (haven't received it yet). I got a question to ask: where are the flooding holes of the Surcouf? Normally they are located at the bottom of the sub, but I can not find them from the plans, I have searched quite a lot plans and pictures of Surcouf. Thank you guys!

                Probably under the hull where the main ballast tanks are located. Not sure why the plans didn't include them, lack of information available maybe?

                  Due to the special hull structure, the Surcouf's midsection pressure-resistant hull appears to be particularly large (because of the need to accommodate the ammunition magazine below the 203mm main gun), so the main ballast tanks are in the bow and stern oriented areas. Even so, I did not find any flooding holes in the various drawings.

                    Perhaps the flood ports were large "Kingston" valves in the box keel? The Brits and others did that. The practice continued right up through the Oberon class. Many ships also vented the ballast tanks under the main deck in the free flood areas of the superstructure through riser piping. Looks like they were completely forgotten about in the plans and the cutaway model!

                      This is the Orp Orzel, the polish submarine during the WW2, and these should be the things you have said, sir.

                      Flooding ports on the box keel, and you can see the large flooding valves nearby:

                      From the plan of Orp Orzel we can see better, the large circle flooding valves on both sides of the keel:

                      New research from the Sous-marin Surcouf plans:
                      Eventually I found the "Kingstons" from the plan, and there are 5 FWD kingston valves and 6 AFT kingston valves (2 of which are in pair) totally, which are colored in green . I guess the valves should be similar to the Orp Orzels' .

                        You've got it, Sam! For Surcouf, there may not be an illustration of flood ports as the drawings and the cutaway model have the outer shell plating stripped away so that we can see the internals. Since there is no plating, we can't see the simple holes for the flood ports. The best thing to use to find those features is usually a docking plan. Those drawings are very specific to identify external features that may need to be worked, or afford access to the insides of tanks and lower superstructures. Unless you do find something, if you are building an operational model, I'd just run a line of holes down the bottom of the box keel and be done with it. Who's gonna dispute it?

                        Take care,
