The Type VIIF boats were designed in 1941 as supply boats to rearm U-boats at sea once they had used up their torpedoes. This required a lengthened hull and they were the largest and heaviest type VII boats built. They were armed identically with the other Type VIIs except that they could have up to 39 torpedoes onboard and had no deck guns.
Only four Type VIIFs were built. Two of them, U-1062 and U-1059, were sent to support the Monsun Gruppe in the Far East; U-1060 and U-1061 remained in the Atlantic. Type VIIF U-boats used the same engines as the Type VIID class. Three were sunk during the war, the last was scuttled after the war along with the majority of the surrendered U boats.
