Project history: German submarines of VIIC series. Negotiations about building of 6 such boats in Spain were conducted with
Germans since early 1940, contract has been signed in July, 1941. G1-6 were authorized by the decree from 25.9.1941, works in Cartagena
were begun in autumn of the same year. Spanish designation of design
was type
16. Germany should deliver machinery and materials for first 4
submarines, including construction steel. Failure of deliveries owing to
crash of "Third Reich" led to program failure. After war Spaniards tried to redesign project
with usage of own materials. 1.2.1949 G5 and G6 were cancelled, and the
order for four first submarines was renewed 15.3.1949. Really building was beyond the power for Spanish industry and
works were limited by building of hull sections for two
submarines, though G1 was formally laid
down 18.5.1953. In 1955 building was completely stopped, ultimately G1-4
were cancelled 20.10.1961.
Unique submarine of VIIC series
commissioned by Spanish Navy became former German U573, damaged 1.5.1942 by
British aircraft and arrived to Cartagena next day. She was not interned and has been put into
repair at Cartagena, but later bought by Spain. Boat was transferred to Spanish crew 2.8.1942, receiving
name G7. She was under repair five years and commissioned by Navy only 5.11.1947, then more than decade
she was the most efficient Spanish submarine.
Modernizations: early 1950s, G7: - 1 x 1 - 20/65
