ISAAC PERAL AND THE FIRST SUBMARINE POWERED BY AN ELECTRIC MOTOR

ISAAC PERAL AND THE FIRST SUBMARINE POWERED BY AN ELECTRIC MOTOR

One afternoon in 1888 a steel beast plunged for the first time into the depths of the sea, in one of the largest military centers in Spain. It carried on board 11 men and its creator, the genius Isaac Peral. That day was the launching of the first naval submarine with electric propulsion, a prototype that revolutionized the navy of the great powers and was decisive in both World Wars.   

Peral was a wise and brave Spanish officer who conquered the secrets of the sea. He built a modern submersible vessel powered by 2 electric motors powered by a battery of 613 accumulators.  

  • It sailed with precision, power and safety. 
  • It fired torpedoes right on target. 
  • It reached up to 10 hours of continuous immersion. 
  • She had a range of 130 miles at 6 knots and 396 miles at 3 knots.  
  • It submerged without leaving the slightest trace on the surface of the water. 

🥇This torpedo submarine, created for coastal defense, could dive horizontally at the desired elevation, thanks to a novel top-secret system that Peral’s creative mind called “depth apparatus“. It was a huge steel hull equipped with several revolutionary technologies, such as: 

A compressed air system for breathing and a purifier to eliminate carbon dioxide. 

  • A cooling system, which prevented the submarine from heating up. 
  • An optical tower (precursor of the periscope), to project the external image onto an optical table inside the ship. 
  • A system of magnetic compensation of the compass, which facilitated navigation. 
  • A torpedo launcher tube, with an arsenal of three missiles. 

The reliability and performance of Peral’s submarine were proven under demanding tests. And although this technological marvel was not taken advantage of in its homeland, Spanish engineering took a bold step into the future and illuminated the world’s naval history. A legacy that endures through time.
