German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1307 had a displacement of 769 t when at the surface and 871 t while submerged. She had a total length of 67.10 m, a pressure hull length of 50.50 m, an overall beam of 6.20 m, a height of 9.60 m, and a draught of 4.74 m. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2800 to 3200 PS for use while surfaced, two AEG GU 460/8-276 double-acting electric motors producing a total of 750 PS for use while submerged. She had two shafts and two 1.23 m propellers. The boat was capable of operating at depths of up to 230 m.

The submarine had a maximum surface speed of 17.7 kn and a maximum submerged speed of 7.6 kn. When submerged, the boat could operate for 80 nmi at 4 kn; when surfaced, she could travel 8500 nmi at 10 kn. U-1307 was fitted with five 53.3 cm torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. The boat had a complement of between forty-four and fifty-two.

Service history
On 9 May 1945, U-1307 surrendered at Bergen, Norway. She was later transferred to Loch Ryan, Scotland on 2 June 1945. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-1307 was one of 116 selected to take part in Operation Deadlight. U-1307 was towed out and sank on 9 December 1945, by rockets from a British Firefly aircraft launched from the escort carrier HMS Nairana (D05).

The wreck now lies at 55.83333°N, -10.08333°W.
