Otto Hahn (ship)
nuclear-powered cargo vessel

Otto Hahn was one of only four nuclear-powered cargo vessels built to date. Planning of a German-built trade and research vessel to test the feasibility of nuclear power in civil service began in 1960 under the supervision of German physicist Erich Bagge. Launched in 1964, her nuclear reactor was deactivated 15 years later in 1979 and replaced by a conventional diesel engine room. The ship was scrapped in 2009.
History
Otto Hahn's keel was laid down in 1963 by Howaldtswerke Deutsche Werft of Kiel. She was launched in 1964 and named in honour of Professor Otto Hahn, the German chemist and Nobel Prize-winner, who discovered the nuclear fission of uranium in 1938. The first captain of the Otto Hahn was Heinrich Lehmann-Willenbrock, a German U-boat ace of World War II.
In 1968, the ship's 38-megawatt nuclear reactor was taken critical and sea trials began. In October of that year, NS Otto Hahn was certified for commercial freight transport and research.
Configured to carry passengers and ore, Otto Hahn made her first port call in Safi, Morocco, loading a cargo of phosphate ores, in 1970. In 1972, after four years of operation, her reactor was refuelled.
This brief starts where responsible research should: with the source description of “Otto Hahn (ship)” as nuclear-powered cargo vessel. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as nuclear-powered cargo vessel. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated May 4, 2026. The linked authority identifier is Q517975. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1960, 1964, 1979 and 2009.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
