German submarine U-1276 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine, built for service during World War II. She was laid down at Bremer Vulkan of Bremen-Vegesack on 13 July 1943. She was commissioned 6 April 1944 with Oberleutnant zur See Karl Heinz Wendt in command. U-1276 was equipped with a submarine snorkel (underwater-breathing apparatus) when she sailed on her last cruise.

Design[edit]

German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1276 had a displacement of 759 tonnes (747 long tons) when at the surface and 860 tonnes (850 long tons) while submerged.[1] 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).[1]

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).[1] 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-1276 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, and an anti-aircraft gun. The boat had a complement of between forty-four and sixty.[1]

Service history[edit]

At 11:45 on 20 February 1945, U-1276 sank HMS Vervain, (Lt. Cdr. R.A. Howell, RNVR in command), a Flower-class corvette escorting convoy HX-337. Vervain sank after 20 minutes about 25 nautical miles (46 km; 29 mi) south-east of Dungarvan, Ireland. The commander, three officers and 56 ratings were lost. Three officers and 31 ratings were rescued. HMS Amethyst (Lt. Cdr. N. Scott-Elliot, DSC, RN in command), which was part of the same convoy, then sank U-1276 by depth charges, off Waterford, Ireland at position 51°48′N 07°07′W / 51.800°N 7.117°W / 51.800; -7.117Coordinates: 51°48′N 07°07′W / 51.800°N 7.117°W / 51.800; -7.117. All hands aboard the U-boat (49) were lost.

Post war[edit]

In 2006, a group of divers from Ardmore Diving discovered the wreck site of U-1276 some 20 nautical miles (37 km; 23 mi) south of Youghal. The submarine is lying in 75 metres (41 fathoms) of water and largely intact, albeit visibly damaged by the depth charges that sank her.
