...more than 160 years after the portuguese navy was founded, and 20 years after Henry the Navigator was dead. Still not as big of a gap as those 19th century references that you linked to reply to a post about 15th century events

		I'm not sure what the organizative reform of Spain has to do with the founding date of Spain and Portugal's navies. In any case, the Spanish Armada is the result of joining the Castilian and Aragonese navies, both dating from the early XIII century: https://armada.defensa.gob.es/ArmadaPortal/page/Portal/Armad...
