A much older submarine, the "Peral" was the first electric battery-powered submarine, built by the Spanish engineer and sailor Isaac Peral for the Spanish Navy. The first fully capable military submarine, she was launched 8 September 1888. She had one torpedo tube (two torpedoes) and an air regeneration system.
The Paseo Alfonso XII, the port of Cartagena, Spain.
The Spanish Navy are building a new class of diesel electric submarines, the first one to be her namesake "Isaac Peral". She has not fared so well due to an engineer putting a decimal point in the wrong place! She is 70 tons too heavy and may not be able to resurface.
