German submarine U-1225 was a Type IXC/40 U-boat of Nazi Germany's Kriegsmarine during World War II.

The submarine was laid down on 28 December 1942 at the Deutsche Werft yard at Hamburg, launched on 21 July 1943, and commissioned on 10 November 1943 under the command of Oberleutnant zur See Ernst Sauerberg. The U-boat then served with 31st U-boat Flotilla, a training unit, until 31 May 1944. She was then transferred to the 2nd U-boat Flotilla for active service.^[1]

Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-1225 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 long tons) while submerged.^[3] The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 in). The submarine was powered by two MAN M 9 V 40/46 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).^[3]

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).^[3] When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,850 nautical miles (25,650 km; 15,940 mi) at 10 knots (19 km/h; 12 mph). U-1225 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) as well as a 2 cm (0.79 in) anti-aircraft gun. The boat had a complement of forty-eight.^[3]

Service history

U-1225 had a short but active career. She departed Kristiansand on 20 June 1944, never to return. Four days out of port, the new submarine was attacked by Canso aircraft of No. 162 Squadron RCAF. The flying boat was shot down, but not before her depth charges fatally wounded the U-boat. All 56 sailors went down with the sub. Three of the eight aircrew from the Catalina were lost as well.^[4]
