In the early stage of World War II, the Americans did not pay much attention to torpedoes, and the MK13, 14, and 15 torpedoes developed (one type, but fired from different vehicles) these torpedoes were all cheating goods, and they harmed many submariners.

However, these torpedoes are all electric torpedoes, which do not bubble, and the torpedo that hit the tanker this time can bubble, then it is obvious that it is a thermodynamic torpedo.

Needless to say? Of course the Germans did it!

In the analysis of the Americans, this matter is too simple.

A considerable part of Mexico's oil exports is exported to the United States, after all, the United States is now in a state of war and is quite hungry for oil, and now if Mexico's oil tankers are blown up so that they cannot export oil, then the United States will be seriously threatened.

The Germans are planning to interrupt the back road of the United States, but unfortunately, this will only make Mexico fall into the scheme, and Mexico can only rely on the United States to survive, so that Mexico wholeheartedly joins its own camp, and then, and then pull South America in, the United States definitely still has hope!

The Germans are so stupid, that Ciric, finally did a stupid thing!

"Then, it's time for us to talk about your oil, we in the United States do not want to see such an ecological catastrophe happen again, you can only stand with us and jointly fight against Germany, it is the most correct path, we can send escort ships to anti-submarine for your oil tankers, if you act alone again, it is likely that you will continue to be sunk oil tankers."

The U.S. ambassador continued to speak smugly, and these words were not the same in the ears of the Mexican president.

This is simply showing off, demonstrating, if you don't follow us, in the future, your tankers, don't think about sailing normally! How can you say this like an American did it?

Valdés couldn't help frowning, this matter must not be so simple, is it that the United States only has electric torpedoes?

No, this matter must be checked carefully!

The Americans were still talking, Valdés and Camacho exchanged a look, and they both saw the worry in each other's eyes, if it was really the Americans who did it, then this kind of behavior is really unforgivable!

Just two years ago, because Mexico nationalized oil, it also led to the hostility between Britain and the United States and Mexico, if it weren't for the change in the situation, maybe the stinky American GIs would have been killed, and now, the Americans are still arrogant, do you really think it is still the last time the Mexican-American war?

Seeing off the American ambassador, the two sat down.

"The truth of this matter must be clarified." President Camacho said: "According to the captain's report, the first torpedo fired by the other side was a dud, right? ”

Camacho was a lifelong warrior, joining Carranza's army in 1915 as a lieutenant and quickly rose through the ranks, eventually to general. In 1932 he became Minister of Army and Navy, and in 1937 he became Minister of Defense.

Therefore, Camacho is quite clear about these things in the army. Now, Camacho keenly grasped the key to it, everything the Americans said was secondary, the main thing was to find the torpedo, as soon as the torpedo was found, everything fell into place.

The Americans say that the Germans did it, then the Germans will also say that the Americans did it, but the torpedoes will not be faked.

"Yes, I'll leave and send someone to salvage in the nearby waters, and I must salvage that dud." Valdés also looked serious.

"This matter is to be carried out in secret, and the Americans must not be allowed to know." Camacho instructed again.

Salvage torpedoes, it is not easy.

When a torpedo is in the water, it sails at a certain depth and does not sink under the sea, but this is because the torpedo is moving.

When the torpedo is sailing in the water, the power plus buoyancy is exactly equal to the gravity of the torpedo, so that the torpedo will not sink, but if the torpedo does not hit the target within range, the power of the torpedo is exhausted, the gravity will be greater than the buoyancy, and the torpedo will sink to the bottom of the sea.

Think about it, too, according to the ancient Archimedes' principle, the weight of the torpedo must be greater than the gravity of the water, that is, because there is power to keep sailing in a straight line, just like an airplane flying in the sky, once it loses power, it will definitely fall.

Something that sank to the bottom of the sea, finding it was a problem.

All this has to be carefully deduced.

"Yes, it's in this sea, I remember very well, about a thousand meters in front of us." Sailor Roy sat in a small boat and instructed several technicians.

After being rescued, Roy couldn't sleep almost every night, and when he closed his eyes, it was those seabirds, sea fish, and now, a few days have passed, the area of crude oil has spread even more, and this black sea has become a place of death.

All of this was caused by that submarine, as long as you let yourself know who did it, you will never let him go!

Thinking of this, Roy raised his fist, he was very angry.

From here, to the front, where the tanker sank, sailed in a straight line, several technicians, carefully calculated on the ship, also taking into account the influence of ocean currents.

"Let's go to the other side, about two nautical miles underwater." The technician drew a circle on the chart with a pen, which, judging by the power of the torpedo, should have fallen in that place.

The biggest advantage here is that it is relatively close to the coast, and the water depth is only 50 meters.

The biggest challenge in diving is the pressure, every 10 meters of descent, it increases by one atmosphere, at a depth of 50 meters, which is equivalent to six times the pressure at sea level, so divers must perform decompression diving.

However, the depth is not particularly deep, so there is no need to wear a rubber wetsuit with heavy full-body equipment.

Several divers, carrying two oxygen cylinders on their backs, and at the same time, two additional high-pressure oxygen cylinders hung on their waists and arms, wearing diving suits, all plopped upside down into the sea after receiving the order.

Their feet flutter against the sea, and at the same time, they begin to breathe in high-purity oxygen for simple underwater phased decompression.

After more than ten seconds, the decompression was complete, and they continued to dive downward, and soon reached the bottom.

Here, the sunlight softly penetrates the sea and turns a pale blue, and all the creatures under the water are floating with the water, and the divers begin to search.

This is bound to be a long process, and the slightest miscalculation can change the final landing point of the torpedo.

But not for someone who is bursting with strings of bubbles popping up in their mouths.
