The strengths and limits of Isaac Peral's submarine

Peral was an important early submarine experiment, but its limited speed, endurance arrangements, and battery constraints show how immature the type still was.

Question

What was Isaac Peral's 1889 submarine like?

Short answer

It was a notable early torpedo submarine, but slow, operationally limited, and not a convincing candidate for the first true submarine claim.

Notes

The answer corrects the date to 1889: Peral was laid down in 1887, commissioned in 1889, and decommissioned in 1890. The roughly 85-ton submerged boat carried one torpedo tube and two torpedoes. A surface speed near 7.8 knots, submerged speed near three knots, and inability to recharge batteries underway sharply limited operational freedom. Even a modest current could overwhelm her underwater progress. The speakers therefore resist calling Peral the first submarine or U-boat while recognizing Isaac Peral's design as an important technical experiment.
