Type IA was designed as Ocean going U-boats. Only two U-boats
were built in this class and that was U-25 and U-26. They
were both constructed by
AG
Weser, of Bremen. This class of U-boat, although they
performed adequately, were difficult to handle an extremely
poor dive rate.
U-25 was commissioned on the sixth of April 1936 and was commanded
by Eberhardt Godt, during U-25 wartime career she sunk eight
ships, and was lost with all hands in August 1940 in the North
sea.
U-26 was commissioned on the 6th of May 1936 and was commanded
by Werner Hartmann, and during U-26 wartime career. She managed
to sink 11 ships in total, finally succumbing to continued
attacks from HMS Gladiolus and aerial attacks from an Australian
Sunderland. U-26 was scuttled on the 1st of July 1940 all
hands survived.
