History
The project of an underwater torpedo bomber was presented by Isaac Peral to the Minister of the Navy of Spain in 1885 . In October 1886, the Minister issued an order launching the project in the implementation phase, and issued the initial budget to the engineer. January 1, 1888 in the shipyard of Cadiz , the keel of the submarine was laid, and on September 8, the submarine was launched.
Tests of the submarine in the dock began only in 1889 and continued until the middle of 1890 . Most of the trials of the submarine were successful, but the commission considered that the cruising range and speed of the boat were insufficient to put it into service. In November 1890, the submarine was delivered to the shipyard of Cadiz , where it was disarmed. Waiting for dismantling, the ship stood for almost 40 years, until in 1929, by order of the commander of the submarine forces of the Spanish fleet, it was towed to Cartagena . Here, the submarine changed its location several times; From December 1, 1965, it was located on the Cartagena Embankment, on Alfonso XII Boulevard, and was an unusual monument- fountain . In connection with the destruction of the hull of the submarine, it was decided to transport it to the Naval Museum of Cartagena. On December 15, 2012, she was transferred to the Naval Museum of Cartagena, where, after the restoration, from September 2013 she was opened to the public.
Features
The hull of the vessel, designed for 12 crew members, was made of steel and had the form of a spindle 23 m long and 2.9 m wide. The displacement of the submarine was 77 tons (at a depth of 85 tons). The maximum immersion depth reached 30 m, the cruising range was about 500 km at an average speed of four knots. A technical innovation was that the propellers were driven by electric motors that were powered by a battery and had a capacity of 30 horsepower each. In the bow of the submarine was installed at that time a unique torpedo tube.
