Type IX D 1
U 180 and U 195 = 2 U-boats
This U-boat Type was built as a particular powerful combat unit by extending the pressure hull´s length while maintaining it´s diameter. Initially these two units were equipped with two sets of three side-by-side Daimler Benz 20 cylinder diesel Engines ( same as in German Fast Attack Crafts) and a Vulcan gearbox generating 9,000 HP for 20.8 kn surfaced. 1943 the U-boats were refitted with standard diesel engines to serve as a fuel supply unit.

Type IX D 2
U 177 to U 179/ U 181 and U 182/ U 196 to U 200/ U 847 to U 852/ U 859 to U 864/ U 871 to U 876/ U 883 = 29 U-boats
These were combat units for long range operations in the Indian Ocean and Far East. It was fitted wth two Diesel generators with 1.00 HP additionally which could be operated together with the two main engines during diesel-electric mode of operation providing for a very long ranhe that could reach up to 31,500 nmi at 10 kn. Therefore these U-boats were able to circumnavigate the Earth without refuelling.
