Mysterious missing submarine, anti-submarine technology is so powerful, why can't you find a submarine?

A friend of mine in junior high school is really a "god". That guy's hands are usually darker than Bao Gong's. Once the teacher made a surprise inspection of personal hygiene. He walked by one by one, and it was almost his turn. I thought he was hopeless. At this critical moment, he picked up my tape and wiped it without saying anything, and his hand turned white. ......

As the main measure for Argentina to make up for the submarine strength after the Falklands War, the Argentine Navy originally planned to build six submarines of this type, but the subsequent economic crisis made several "home-made boats" of this class disappear and became the only three submarines in the Argentine Navy. "Pillar".

Technically, TR- 1700 was the mainstream configuration at that time. It has a displacement of more than 2,000 tons, a maximum underwater speed of 25 knots, a diving depth of 300 meters, and a self-sustaining force of 30 days. It has 22 torpedoes and 6 torpedo tubes, and it also belongs to an advanced conventional submarine with good performance in the early 1980s.

1985, San Juan is online. The boat is regarded as a symbol of Argentina's coming out of the shadow of Falklands War and improving the modernization level of the army.

On the same day, the Argentine navy said that the sonar of two ships under its command detected the sound of suspected submarine crew knocking on the hull for help. However, according to the analysis of the crew of the American P-8A anti-submarine aircraft, these signals are not from man-made, but from the marine background noise or the sounds made by marine life.
