In 1749, he travelled incognito under the name of Mr. Josues and learned all that he could in England ,and brought back 50 British naval constructors. In an ironic twist, many of them went on to build the Spanish ships that would later fight in the American Revolutionary War and the battle of Trafalgar. He was, however, disappointed with the English naval construction methods and upon his return to Spain in 1750, he was placed in charge of Spanish naval construction, creating his own naval construction system (approved in 1752) and improving the shipyards (such as the ones in Cartagena, Cádiz, Ferrol, Havana) and armaments. He implemented modern industrial division of labor among the different disciplines involved in naval construction such as dry-docks, shipyards, furnaces, rigging, and canvas
