German submarine U-1065 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.
She was ordered on 14 September 1941, and was laid down on 23 September 1943 at Friedrich Krupp Germaniawerft, Kiel, as yard number 702. She was launched on 3 August 1944 and commissioned under the command of Oberleutnant zur See Johannes Panitz on 23 September of that year.
German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1065 had a displacement of 759 tonnes (747 long tons) when at the surface and 860 tonnes (850 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-1065 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, (220 rounds), one 3.7 cm (1.5 in) Flak M42 and two 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.
U-1065 had a very short career. While she was commissioned on 23 September 1944, she was not assigned to a flotilla until 1 April 1945. She spent the intervening six months training with the 5th U-boat Flotilla. At the end of her training, she was formally assigned to the same flotilla. She began her first patrol on 4 April 1945, but was sunk after only six days at sea.
U-1065's first patrol took her from her home port of Kiel in northern Germany towards occupied Norway. However, while en route to Norway in company with another of the Flotilla's boats, U-804, the two submarines were detected and attacked in the Skagerrak strait by 34 de Havilland Mosquito aircraft from three separate Royal Air Force squadrons. During the attack, U-1065 was able to shoot down one of the Mosquitos with her anti-aircraft guns. However, she was then hit by several rockets from 10 separate Mosquitos from 143 and 235 Squadron; she exploded and sank with the loss of her entire crew of 45 men.
The accompanying vessel, U-804, was also hit by rockets from the Mosquitos during the altercation. She exploded and rapidly sank with the loss of her entire crew of 55 men.
