German submarine U-573 was a Type VIIC U-boat built for Nazi Germany's Kriegsmarine for service during World War II.

Her keel was laid down 8 June 1940 at the Blohm & Voss yard in Hamburg as yard number 549. She was launched on 17 April 1941 and commissioned on 5 June with Kapitänleutnant Heinrich Heinsohn (12 February 1910 – 6 May 1943) in command. Heinsohn commanded her for her entire career in the Kriegsmarine. In May 1941 he had arranged that the city of Landeck in Tyrol adopted the submarine within the then popular sponsorship programme (Patenschaftsprogramm), organising gifts and holidays for the crew, earning her the honorary name "U-573 Landeck".

The boat began her service career as part of the 3rd U-boat Flotilla when she conducted training; on 1 September 1941 she commenced operations with that flotilla. She was transferred to the 29th Flotilla, also for operations, on 1 January 1942. She was sold to the Spanish Navy that same year and became the Spanish submarine G-7.

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-573 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 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 Brown, Boveri & Cie GG UB 720/8 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).
