The first navigable submarine was built by Cornelius Drebbel in 1620 using the 1578 plans of English mathematician William Bourne.
William Bourne never constructed a submarine; though he is credited by historians with inventing it, his claim to fame in the submarine world is that he was the first to draw a publish a design (1578) from which Cornelius Jacobszoon Drebbel built the first navigable submarine (1620).
Cornelius Drebbel did not actually invent the submarine. He was the first person to manufacture a workable submarine, but he used the 1578 plans of English mathematician William Bourne. Drebbel built his submarine using a wooden frame tightly wrapped with waterproof leather.Cornelius Drebbel did not actually invent the submarine.

Every submarine since Drebbel's first in 1578 has been able to reach the ocean floor. Not all have been able to resurface, though.

The first navigable submarine was built in 1620 in England by Cornelius Drebbel using English mathematician William Bourne's plans from 1578. America (not the US back then) used the first submarine, built by American Colonist David Bushnell in 1776.
In 1620 a navigable submarine was built by Dutch inventor Cornelius Drebbel (who was in the employ of James I of England) from a design published in 1578 by English mathematician William Bourne.
