Kriegsmarine U-Boat Type IXC40
The German Type IX was designed in 1935-1936 as large ocean-going U-boats, they were derived from Type IA. Fitted with 6 torpedo tubes below the waterline (4 at the bow and 2 at the stern) they carried 22 torpedoes. Type IX had 5 external torpedo containers (3 at the stern and 2 at the bow) which stored 10 additional torpedoes.
Type IXB was an improved version of Type IX with increased range, and slightly heavier. Type IXC was a further development with storage for additional fuel which gave them increased range up to 13,450 n/miles at 10 knots.
The IXC40 boats were a slight modification over the Type IXC , with a slightly increased range, somewhat higher surface speed and were a bit heavier at 1,545tons fully loaded and submerged.
