>He also built the first navigable submarine in 1620 while working for the English Royal Navy.[23][24] He manufactured a steerable submarine with a leather-covered wooden frame. Between 1620 and 1624 Drebbel successfully built and tested two more submarines, each one bigger than the last. The final (third) model had 6 oars and could carry 16 passengers. This model was demonstrated to King James I in person and several thousand Londoners. The submarine stayed submerged for three hours and could travel from Westminster to Greenwich and back, cruising at a depth between 12 and 15 feet (4 to 5 metres). Drebbel even took King James in this submarine on a test dive beneath the Thames, making King James I the first monarch to travel underwater.[25] This submarine was tested many times in the Thames,[26] but it failed to attract enough enthusiasm from the Admiralty and was never used in combatit supposedly used hydrogen peroxide to provide oxygen underwater.

>>65246308>what could have beenYes? What could have been its martial application? There was no offensive armament and a capacity of 20 men (let's be generous here) is negligible. And maritime infiltration could simply be carried out by low bottomed small boats or swimmers.
>>65246308Didn't they show this in The Three Musketeers movie?
>>65246880That's not a submarine.
>>65246308Hydrogen peroxide wasn't synthesized until 1818.
>>65252345It's sub. It's marine. Can't please everyone.
