The Komet was a German auxiliary cruiser (HSK-7) active during World War II, originally launched as the merchant ship Ems on 16 January 1937 at the Deschimag A.G. Weser shipyard in Bremen. Built for Norddeutscher Lloyd, she measured 115.5 meters in length, with a beam of 15.3 meters and a draught of 6.5 meters, registering 3,287 gross register tons (GRT). Powered by two diesel engines, she could reach speeds of up to 16 knots (30 km/h). After her requisition in 1939, she was converted into an auxiliary cruiser at Hamburg's Howaldtswerke and commissioned into the Kriegsmarine on 2 June 1940. Her armament included six 15 cm guns, one 7.5 cm gun, a 3.7 cm and four 2 cm anti-aircraft guns, and six torpedo tubes. She also carried a small 15-ton fast boat, Meteorit, designed for mine-laying, and an Arado 196 A1 seaplane for reconnaissance. Komet’s notable service began with her Arctic voyage through the Northern Sea Route, aided by Soviet icebreakers like Lenin and Joseph Stalin, under the command of Kapitän zur See Robert Eyssen. She disguised herself as the Soviet icebreaker Semyon Dezhnev and later as the Donau during her passage. Her journey into the Pacific involved raiding Allied merchant shipping, sinking several vessels, and attacking the phosphate facilities on Nauru in December 1940, damaging significant infrastructure and disrupting Allied operations in the Pacific. Her subsequent patrols included hunting Allied ships in the Indian Ocean, where she sank additional vessels and captured valuable cargo. She returned to Germany in November 1941 after sinking seven ships totaling approximately 41,568 tons. In October 1942, after repairs, Komet embarked on another sortie into the Atlantic disguised as a minesweeper. She was sunk on 13 October 1942 by British motor torpedo boats near Cap de la Hague, with the engagement resulting in no survivors from Komet. Her wreck was discovered in 2006, lying upside down at a depth of 55 meters, with her remains revealing the destructive explosion that led to her sinking. Komet remains a significant example of German naval commerce raiding and Arctic navigation during WWII.
