German auxiliary cruiser Orion

Blohm & Voss in Hamburg built the ship as a freighter for the Hamburg America Line (HAPAG). To save money, steam turbines from the liner New York were re-used. That proved a poor decision, since the Orion was plagued for her entire life by engine problems.

After the war began the German Seekriegsleitung (Naval Operations Command) was ill-prepared for raider warfare. The operations of the German auxiliary cruisers of World War I were evaluated and considered a great success, having disrupted British merchant shipping around the world. However the overall effect on the war was evaluated as having been rather minor and so only a small program of converting merchant ships into auxiliary cruisers was initiated on 5 September 1939.

The first two ships being requisitioned were the Kurmark (Orion) and the Neumark (German auxiliary cruiser Widder), and conversion started immediately.

One of Germany's first auxiliary cruisers in World War II, Orion left Germany on 6 April 1940, under the command of Korvettenkapitän (later Fregattenkapitän) Kurt Weyher. Disguised as a neutral ship she passed south through the Atlantic Ocean, where she attacked and sank Haxby, a 5,207 GRT freighter.

In May 1940 Orion rounded Cape Horn and entered the Pacific Ocean. She entered New Zealand waters in June 1940 and laid mines off Auckland during the night of 13–14 June 1940, one of which sank the ocean liner RMS Niagara five days later. Two other ships struck mines from Orion, as did two trawlers and an auxiliary minesweeper.

Orion then raided across the Indian and Pacific Oceans attacking four more ships. One ship, the Norwegian freighter Tropic Sea, was captured without a fight and sent to occupied France as a prize, though she was scuttled in the Bay of Biscay after encountering HMS Truant. The other ships encountered by Orion were sunk.

On 20 October 1940 she rendezvoused with the German auxiliary cruiser Komet and supply ship Kulmerland. Operating together, they sank another seven ships, including the liner Rangitane and five ships off Nauru, before going their separate ways in the new year.

The German naval attaché to Japan, Vice-Admiral Paul Wenneker, bought a Nakajima E8N float plane early in 1941. It was dispatched on board the supply ship Münsterland to rendezvous with Orion at the Maug Islands in the Northern Marianas. They met on 1 February 1941, and Orion thus became the only German naval ship of World War II to use a Japanese float plane.

Another six months cruising in the Indian Ocean yielded nothing, though she did encounter and capture her final victim, Chaucer, in July 1941, in the South Atlantic when Orion was on her way home.

Orion returned to Bordeaux in occupied France on 23 August 1941. After 510 days and 127,337 nautical miles (235,828 km) at sea she had sunk ten ships with a combined tonnage of 62,915 gross register tons (GRT), plus two more (totalling 21,125 GRT) in cooperation with Komet.

The German freighter Anneliese Essberger, disguised as the Norwegian freighter Herstein, was meant to meet the Orion on 30 Aug. 1941. The planned rendezvous was Point Corona at 28 degrees N, 43 degrees W. But the freighter failed to see the Orion, and continued north.[2]

De-commissioned as a commerce raider, the ship was renamed Hektor in 1944 and was used as artillery training ship. In January 1945 she was again renamed Orion and was used to take refugees from Germany's eastern provinces across the Baltic Sea to ports in northern Germany and occupied Denmark. On her way to Copenhagen on 4 May 1945, after she had picked up the crew of the old battleship Schlesien, Orion was hit by two bombs dropped by aircraft of the Soviet 51st Mine-Torpedo Aviation Regiment off Swinemünde. The crew managed to beach the fiercely burning ship on a sandbank, but more than 150 passengers and crew were killed.[1] The hulk was scrapped in 1952.[3]
