Known as the world's most advanced conventional power submarine, the displacement is miscalculated by 70 tons. What happened afterwards?

Later, because the buoyancy was too small, the submarine could not float again after launching. Before World War I, the Spanish navy was still very strong in the world, but after World War I, the Spanish navy began to decline slowly, so that now their navy is more and more despised, especially in some countries with strong navies, so they want to change others' views and be recognized by the world again, so they started the S-80 submarine plan.

When this submarine started, Spain was very confident, claiming that it was the most advanced conventional submarine in the world. According to the information released by Spain, we can know that the displacement of this submarine can reach 2626 tons, and the power is AIP propulsion, so just looking at these data, we can see the determination of Xiban to make a comeback this time. It is estimated that the designer is too confident about this submarine, or maybe he is too excited. As a result, he made a mistake in the decimal point data, which led to the displacement of the speedboat of more than 70 tons and the buoyancy could not be lifted.

This mistake once again put Spain in an awkward position. It is not difficult to design this submarine. Not as troublesome as a boat, but data is the key. One wrong step will be wiped out, so generally you can build submarines with conventional forces as long as you have money. It's just that it's a little difficult to build a submarine with such a large tonnage, so only a few countries have the strength, but the key point is that Spain didn't have this Jin Gangzuan and took this porcelain job, so this time Spain made the world see a joke.

But the failure of Spain is not only a technical mistake, but also a key point is that they don't trust our technology in China, so our technicians haven't fully disclosed the technical points. In fact, they had learned from China's S-26 and asked our technicians in China before planning, but the Spanish technicians were so disdainful of our technology that they didn't give us a separate list, but distributed it to many European countries, which indirectly caused their design failure this time.
