"Schwabenland" was borrowed from Lufthansa for the 1938-1939 Third German Antarctic Expedition. The ship sailed in secret from Hamburg on 17 December 1938, carrying a complement of 82 men and two Dornier Wal seaplanes. The ship contacted the German whaling fleet off Bouvet Island, then anchored near the edge of the pack ice at 69°14′S, 4°30′W. After the expedition had completed its work, "Schwabenland" headed north on 6 February 1939, reaching Germany again on 11 April.
World War II and fate.
In October 1939 "Schwabenland" entered Luftwaffe service and used Blohm & Voss BV 138 seaplanes. After the fall of France it was stationed off the coast of Occupied France, based from the ports of Le Havre and Boulogne.
In August 1942 it was transferred to Tromsø, Norway.
The ship was damaged and forced to beach by the British submarine in 1944 which was attacking a convoy off Flekkefjord, Norway. "Schwabenland" was then run aground at Sildeneset in Abelnes Harbour, and later refloated. When the war ended, the ship was taken by the British, and on 31 December 1946 it was loaded with poison gas ammunition, and scuttled in the Skagerrak.
