.Laid down on 15 March 1943 at the Deutsche Werft in Hamburg, and commissioned on 26 January 1944 under the command of Kapitänleutnant Hans Hilbig, it only undertook one patrol, operating from Horten Naval Base, Norway, returning safely to Kristiansand, Norway in early 1945.
Design
supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[1]
The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of forty-eight.[1]
Service history
Its one war patrol was of historical interest less for its role in the
spies
to the United States.
Operation Magpie
Eric Gimpel were landed at Hancock Point in the Gulf of Maine on 29 November 1944 in Operation Elster
("Magpie"). The mission was intended to gather technical intelligence but failed, and both spies were captured.
Fate
At the end of the war it was captured by the
Allies, transferred to Loch Ryan in Scotland, and sunk on 17 December 1945 by the Royal Navy frigate HMS Cubitt as part of "Operation Deadlight
". Unusually for a U-boat, U-1230 does not seem to have suffered any casualties during the war.
