What year did the Spanish navy go to the bottom of the ocean? Why was this a turning point in history?
(ill give u brainliest answer if answered correctly)

1588; The defeat of 1588 led to a reform of fleet operations. The navy at this time was not a single operation but consisted of various fleets, made up mainly of armed merchantmen with escorts of royal ships. The Armada fiasco marked a turning point in naval warfare, where gunnery was now more important than ramming and boarding and so Spanish ships were equipped with purpose built naval guns
