Editing German submarine U-573 (section)

==Spanish service==
Work started on the ''U-573'', now the ''G-7'', in August 1943 following the sale to Spain but took four years to complete. The damage caused by the British attack was found to be more extensive than was first thought; also German technical assistance and parts were difficult to obtain in the last years of World War II and after. In addition, Spain's economy was weak following the [[Spanish Civil War]]. Repairs were completed in early 1947 and on 5 November 1947 ''G-7'' was re-commissioned. The bow's [[Net cutter (submarine)|net cutter]] and the 20mm anti aircraft cannon were removed.

Despite the Type VII being out-dated by the end of World War II, ''G-7'' was the most modern of Spain's submarine fleet; her other vessels (two ex-Italian, and four home-built boats) dating from the early 1930s. ''G-7'' lacked radar and did not possess a [[Submarine snorkel|snorkel]]. In 1951 development was started on a snorkel design by [[Empresa Nacional Bazán]], the Spanish shipbuilding company, but these came to nothing when the Spanish Navy bought the former US Navy submarine {{USS|Kraken|SS-370|6}}.

''G-7''{{'}}s repairs were completed in 1947. In 1958 Arca-Filmproduktion GmbH rented ''G-7'' to take part in the semi-fictitious movie ''[[U 47 – Kapitänleutnant Prien]]'', partially based on his patrol to [[Scapa Flow]], where he sank {{HMS|Royal Oak|08|6}}.<ref>On the film cf. [https://www.imdb.com/title/tt0052329/ U47 – Kapitänleutnant Prien] on [[Internet Movie Database]].</ref>

In 1961 the Spanish Navy's submarine force was re-numbered, and ''G-7'' became ''S-01''.

One other U-boat was interned in Spain during World War II: {{GS|U-760||2}}.

On 2 May 1970 she was de-commissioned after 23 years service. She was auctioned for 3,334,751 Pts (about US$26,500), after which, despite efforts to save and preserve her as a museum, the submarine was [[Ship breaking|broken up]] for scrap.
