From 1909 until the Spanish Civil War, naval construction in Spain was monopolized by the Sociedad Española de Construcción Naval – (SECN) also Spanish Society for Naval Construction (SECN). During this time the majority of its shares were owned by the United Kingdom firm (John Brown and Vickers-Armstrong[1]), and therefore almost all ships built by the company were developed after Royal Navy designs.
For a period of sixteen years, all the technicians were exclusively British, and the situation was not altered till 1925 when the management was taken over by Spanish engineers, as one of the new policies introduced by the then newly created government, including ministers both civil and military, of the dictator Miguel Primo de Rivera[13] (1923–1930). The arrival of the British coincided with the construction of a local electric-powered trolley streetcar's line (1924–1961).[14]
In sight of the outbreak of the Spanish Civil War, and because there was fear of social unrest in the naval station, the Foreign Office in London,[15][16] organized a ship to repatriate all the remaining British citizens and on 22 July 1936 HMS Witch (D89)[17] departed from Ferrol back to Britain.
^"SPANISH NAVY: Huge Contract in British Hands" (1909) The Manchester Guardian, 1 February 1909, Page 12: Manchester "... Vickers, Armstrong and Brown... it has been determined to put down a new shipyard at Ferrol in Spain... Mr A J Campbell... has been appointed manager of the Ferrol yard... Mr Peter Muir ... has been appointed assistant manager. A considerable number of expert shipbuilders have sign on to go to Spain... there is a reason to believe that employment will be found to some hundreds of British shipbuilders, engineers, electricians, and other tradesmen in the new Spanish yard for several years to come."
