Re: Type-IX 'Schnelltauchback" modification?

The "Schnelltauchback" modification was applied to some U-Boats in the later years of the war, when the Allies dominated the air. The reloads from external containers to the boat's internal stowage was rather difficult because of presence of the enemy airplanes.
Moreover, the external, upper deck torpedo containers were withdrawn from use because of frequent damages from depth charges. And finally, increasingly used G7e type torpedoes cannot be stored in upper deck due to impossibility of maintenance.
The number of internally carried torpedoes were not increased due to lack of room.
The modification reduced the dive-time because the narrowed shape of the upper deck facilitated the escape of air, which was traped under the casing. This - in turn - shortened the dive-time by about 10-15 sec.
