    Type II-B German U-Boat

    The Type II-B was a slightly improved version of the original 'dugout canoe' primarily with increased bunkers and radius. Only a handful were built; U-7 through U-24 plus U-120 and U-121. They were used mainly for training. The Type II-B carried six torpedoes or eight mines.

    Type II-C German U-Boat

    The Type II-C was a slightly improved version of the Type II-B with increased bunkers and radius plus slightly more powerful electric motors. Only a handful were built; U-56 through U-63 and were used mainly for training. The Type II-C carried six torpedoes or eight mines.

    Type VII-B German U-Boat


    The Type VII-B was slightly enlarged over the initial variant and the saddle tanks were modified to improve seaworthiness as well as extend bunker capacity and range. More powerful diesels were installed for greater surface speed.

    More VII-B boats were built than the initial variant, but still not so many. They were U-45 through U-55; U-73 through U-76; U-83 through U-87 and U-99 through U-102. The three top ACES of the early years drove Type VII-B boats. All three were sunk early in the war - Prien on 7 March 1941 then Schepke and KRETSCHMER within hours of one another on 17 March 1941.

    By the time my father, a USN LCDR was sent to Europe as part of the Naval Technical Mission, it was late in the war, and the German subs had acoustic homing torpedoes (T-V torpedoe in chart above). He told me the goal of every captain in the convoy was not to be last in line.

    German U-Boat Torpedo T V (G7es) Acoustic Homing - Specification

    If the TV (G7es) Acoustic Homing Torpedo missed an escort, it would home in on a transport.
