In the port of Cartagena, you can see the first submarine built in history. It was designed and built by Lieutenant Isaac Peral. The Peral submarine was the first that: included a torpedo, was propelled by electric motors, had periscope, and solved the problem of oxygen inside. It had capacity for 12 crew. This submarine that could dive to 30 meters, was built in September 1888 (although it was in 1885 when he had the idea).
This invention warlike was intended to serve to defend the territories began to haunt the U.S.A. emerging superpower.
Despite all the innovations that warlike posed this invention for the Spanish Navy but was not supported by the ministry of defense, because the then Minister saw Isaac Peral as an opponent to head the ministry. Finally, in 1890, decided to dismantle it. But they did'nt scrapped, and so, fortunately, we still here so you can be visited the first submarine, which was also invented by a Murcian (from Cartagena).
