German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-643 had a displacement of Шаблон:Convert when at the surface and Шаблон:Convert while submerged.Шаблон:Sfn She had a total length of Шаблон:Convert, a pressure hull length of Шаблон:Convert, a beam of Шаблон:Convert, a height of Шаблон:Convert, and a draught of Шаблон:Convert. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of Шаблон:Convert for use while surfaced, two Brown, Boveri & Cie GG UB 720/8 double-acting electric motors producing a total of Шаблон:Convert for use while submerged. She had two shafts and two Шаблон:Convert propellers. The boat was capable of operating at depths of up to Шаблон:Convert.Шаблон:Sfn
The submarine had a maximum surface speed of Шаблон:Convert and a maximum submerged speed of Шаблон:Convert.Шаблон:Sfn When submerged, the boat could operate for Шаблон:Convert at Шаблон:Convert; when surfaced, she could travel Шаблон:Convert at Шаблон:Convert. U-643 was fitted with five Шаблон:Convert torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one [[8.8 cm SK C/35 naval gun|Шаблон:Convert SK C/35 naval gun]], 220 rounds, and one twin [[2 cm FlaK 30|Шаблон:Convert C/30]] anti-aircraft gun.

Service history
On 8 October 1943, while operating against convoy SC 143, U-643 was detected by Liberator R of No. 86 Squadron RAF. The aircraft strafed the U-boat but had to return to base short on fuel. Another British aircraft, Liberator Z of the same squadron, continued the attack on U-643, which attempted to dive. Four depth charged were dropped in the wake of the diving U-boat, which resulted in an oil spill. Liberator Z returned to the convoy, only to return an hour later to find Liberator T of No. 120 Squadron RAF attacking an U-boat, which turned out to be U-643. The two aircraft attacked with depth charges and strafed the U-boat. When two more Liberators arrived at the scene, the U-boat's crew prepared to abandon ship. Upon arrival of the destroyer Шаблон:HMS the U-boat was scuttled, 18 survivors were picked up by Orwell.Шаблон:Sfn
