On 22 August 1941, BdU (Befehlshaber der U-Boote, U-Boat High Command) directed a query to TVA (Torpedoversuchsanstalt, Torpedo Experimental Station), if G7a (T I) wet-heater torpedo could be modified in such way that after travelling the pre-set distance, it would start to circle with diameter of 1000 – 1500 meters.
This query resulted from the idea that in the case when torpedo missed the target in convoy, the remaining torpedo run could be utilized to circle (inside the convoy), thus creating the another chance for hit.
