G7e/T3
Improvements in the design of the G7e/T2 were incorporated into the production of the next model of electric torpedo for Germany's U-boat fleet. Introduced in 1942, the T3 represented a vast improvement over the early T2. The faulty exploders from the T2 were scrapped in favor of a new design.
The T3 had a range of 5000 m and could achieve 30 kt. With the improved design of the T3 and the new exploder, the G7a steam torpedo was totally superseded and was rarely used for the remainder of the war. Using the T3's perfected proximity feature, U-boat captains could effectively fire under the keel of a ship and break the back of their targets with a single torpedo, increasing the overall effectiveness of the U-boat fleet. The T3 could be fitted with both the FaT (Flächenabsuchender Torpedo) and LuT (Lagenunabhänger Torpedo) pattern running systems for convoy attacks.
Though many opportunities had been missed due to the defects of the T2 torpedo, with the new T3 U-boats were deadlier than ever.
