What is the reason behind the submarine's failure to float?

The reason behind the submarine that cannot float is that the designer miscalculated a decimal point.

When it comes to submarines, people will definitely think of a series of horrible terms such as "ocean black hole" and "deep-sea killer".

As early as 1989, Spain began to plan the construction of a new generation of submarines. The planned new S-80 submarine will be used to replace the old S-60 submarine. However, with the disintegration of the Soviet Union, the biggest threat, Spain suddenly lost the motivation to develop new submarines: anyway, the threat was gone and the war could not be fought, so why spend this money! As a result, the new submarine construction plan ran aground!

However, the 9 1 1 incident once again stimulated the nerves in Spain. Of course, it is unreasonable to restart the project that has been stagnant for ten years without improving the design index. Therefore, the Spanish Ministry of Defence requires the S-80 to be able to perform tasks such as ocean cruise, coastal surveillance and intelligence gathering.

The new S-80 submarine has a total length of 7 1 m and a full displacement of 2,430 tons. The submarine adopts the most popular advanced AIP propulsion system and can cruise underwater for a long time. In order to reduce the design risk, the project also embraced the thigh of Lockheed Martin of the United States and was responsible for the research and development of weapon systems. In 2003, the Spanish government approved the construction proposal of this type of submarine, and plans to deliver the first batch of four submarines in 20 1 1.

When the first submarine was about to be completed, engineers found a fatal problem: the submarine under construction was 70 tons more than the design weight. If the construction is continued according to the situation at that time, the final weight of this submarine will exceed the design index of 125 tons. This level is fatal, and such overweight also means that the submarine will sink directly to the bottom of the sea after launching and will never float up again. This is in trouble.

Such a country's key equipment is matched with such a joke, so we must check it. The survey results show that there are technical errors in the design scheme, which makes a group of data decimal points misplaced. This result made Rafael Balda, former director of the Strategic Evaluation Office of the Spanish Ministry of Defence, sigh: "This may be the heaviest decimal point in history".

There is no choice but to restart the design work. Results The original captain's 7 1 meter was directly extended to 8 1 meter. Although the problem of buoyancy was solved by lengthening the submarine, the wharf originally built for the submarine could not be put down. In addition, after this toss, the service time of the boat was directly pushed to 2022.
