After a "hard" search, Iraq's search personnel were almost giving up and finally found that the target they were looking for did not fall on land, but fell into the Caspian Sea!

They heard the news and witnessed the situation. These residents were Arabs. They had a good impression of the arrival of the Iraqis. Naturally, they were also the most credible. They saw the black shadow falling into the waters of the Caspian Sea more than ten miles away from them. The time and place were more consistent with the speculated black bird's falling situation. Moreover, afterwards, the surrounding sea water was overturned with a dead fish, and they were all cooked, as if the temperature was very high.

So, after finding the target area, Iraq immediately notified the Soviet Union and sent people to guard the surrounding waters.

After the Soviet Union received the news, it immediately sent divers to conduct on-site investigations, because the Iraqi navy was very weak. As for the Iraqi navy divers, they still did not graduate from the Naval Academy in Basra.

The survey was handed over to the Soviet dives. After surveying the exact waters, they would salvage them. The Soviet Union felt very lucky that if the plane crashed onto the land, then what they could get might be some fragments. Now, after entering the water, then what they got was probably a complete plane!

Thinking of a complete SR-71, the most mysterious reconnaissance aircraft for the Soviet Union, and the MiG-25 can fly to three times the speed of sound. The Soviet aviation engineer and the chief designer of the Migoyan Design Bureau, I feel itchy.

However, even Iraq only temporarily obtained news about the approximate location of the plane. They blocked the sea surface here, and they had to search for the specific location of the plane's fall.

The Soviet Union had to use its own strength for this transaction, but the Soviet Union was already very satisfied.

A Soviet diver brigade came here by helicopter, then rented a civilian boat and began the search work.

Because, Turkey is the west of the Caspian Sea, they did this to avoid alarming Americans. If Americans knew that the black bird fell here, they would not be willing to give up.

What they didn't know was that the United States went through a lot of hardships and was also searching for the two missing pilots and the black bird.

Regardless of whether it is a mechanical failure or not, in short, the black bird has not flew back, then there is a possibility of leaking the secret. Although it has been several months since the Americans have not given up and are still looking for it.

Moreover, at this critical moment, the CIA finally obtained useful information. They discovered that Iraqi armed personnel secretly blocked the waters near Tongkabon in the Caspian Sea. They also came to this conclusion by analyzing a large number of satellite images and the flight routes of the black bird at that time: they have not found the wreckage of the black bird so far, and the black bird probably fell in the Caspian Sea!

So the United States also sent its own divers to search for the sea area quietly. Moreover, they targeted the blocked sea area.

On the sea, the wind was calm and unaffected by any tension in the Middle East, but underwater, a silent confrontation was beginning in a fierce state.

In order not to be discovered by Iraqi personnel, American divers started the water from an ordinary civilian ship far away from that area. In order to complete long-distance diving, they carried three oxygen cylinders on their backs and used a large underwater water jet propulsion system.

From the outside, this propulsion system is similar to a torpedo and uses the same battery as a torpedo. However, in order to prevent scratching the user, a ducted water-spray propulsion system is used. There is an outsourcing protective layer outside the coaxially reversed propeller.

This propulsion system can greatly reduce the fatigue caused by divers' long-term diving, and can be called their underwater taxi.

The divers wore two flashlights on their heads. Although the water was still brighter now, in order to better discover the target, they still needed to use this kind of thing to observe more carefully at critical moments.

As they moved forward, behind them, bubbles emerged. This was their diving device, namely the scuba lungs, which were spitting out bubbles.

Scuba, also known as self-portable underwater breathing device, people can breathe freely by diving into the water. In sea water, pressure is the biggest enemy. For every 10 meters increase in depth, the water pressure increases by 1 atmospheric pressure. If the air pressure is higher than the normal air pressure, the nitrogen in human blood and tissues will be highly concentrated; if the pressure drops rapidly, the nitrogen in human organs and blood vessels will have a toxic effect, causing the diver to die. Scuba can give divers the same pressure as the ground air in sea water. The diver's own breathing can be controlled by the scuba's regulation of the air supply and the air pressure when entering the lungs. The diver takes it with him and put on a vest with high-pressure air inside to dive into the water 50-60 meters deep.

Scuba, flippers, and diving goggles are the equipment of ordinary divers. For divers who are now entering the water, they also add flashlights, diving watches, underwater water jet propulsion systems, and their essential diving knives.

Underwater is dangerous. In addition to encountering large underwater creatures, they may also encounter unknown other underwater personnel, and there may be battles.

Underwater, weapons and guns commonly used by humans are unusable because the water has great resistance. If the bullets rotated out cannot move a few meters in the water, they will deflect greatly due to the action of the water, and then fall into the water below. Therefore, after the American frogman enters the water, he can only use the most common cold weapon of humans: the knife.

Three oxygen cylinders, enough to provide several hours of oxygen, they rushed to the water of the scheduled sea area for an hour, searched for it, and then returned.

The previous group of twenty frogmen has gone back and has gained nothing. They hope they will have better luck.

The underwater water jet propulsion system in your hand is working hard. Although the noise is high, it is insignificant compared to the noise emitted by the submarine. At most, it will be found within ten meters. This will not be too risky in their visually visible area.

No one would sit on this kind of propulsion system. Although it felt like sitting in a car, it would bring great resistance. They would all hold the handrails above to keep their bodies parallel to the underwater propulsion system, and shuttle forward in the water like flying in the sky.

Henry looked around with a vigilant look. He was a special SEAL. This time, he participated in this search mission. However, he was very repulsive of this underwater propulsion system. He liked to swim freely. Instead of holding the two grips now, like a tractor, he reminded him of the torpedo submarines of the Japanese Kamikaze Squad.

Henry and his teammates were about to arrive soon. They were vigilant again. They turned on their flashlights and paid attention to the situation under the sea, hoping to find the blackbird that fell into the US Air Force in advance.

This is like looking for a needle in a haystack and wanting to find it. You have to have great luck in it.

They didn't know that in this sea area, other frogmen were also looking for the whereabouts of the black bird.

Kochakin's feet were flexibly swinging like a cheerful fish swimming in the water. They were conducting a carpet-style search, searching for the bottom of the water in this sea area over and over again. They hoped to find the target they were looking for.

Suddenly, Kochajin found a large bubble in front of him. His heart suddenly became nervous.

Those bubbles may be big fish or frogmen.

Although big fish will not invade frogmen underwater, if the large fish are hungry, they may not care whether they are delicious or not. They will be in danger to themselves.

If it were a frogman, it would be even worse, because their own frogman uses this closed circulation system, and there will be no bubbles, and the ones that have bubbles will only be another team of frogmen, and that team of frogmen may be from Turkey.

Kochajin looked at the bubbles in the distance and quickly took out the APS underwater assault rifle he carried on his chest.

The Soviet Union spared no effort in military investment, and underwater combat was only a small-scale action, but the Soviet Union also put a lot of energy into it.

At first, the Soviet underwater frogmen were only equipped with knives and AK rifles. These rifles were only waterproof on the outside and could only be used on the water surface. Therefore, the only underwater weapon that effectively deals with enemy frogmen was the submersible knife, which was used after the frogmen came ashore.

Therefore, in the suburbs of Moscow, an ordinary company called "Tesinitchimasi", its official name is "Central Precision Machine Manufacturing Research Institute". The designer Rashimier-v-Simonov was responsible for the development work.

They first developed the pistol used by the Frogman troops when performing underwater alert missions, the model is SP-1. After equipping the Frogman troops, they soon discovered that this weapon is very effective, but it is only suitable for use at a relatively close distance and cannot attack targets at a longer distance. So the more powerful APS underwater assault rifle was born.

APS Underwater Assault Rifle is an underwater gun derived from the AK system. It adopts the principle of automatic air conduction operation, a rotary bolt, and is open to strike. There is a safety/fast and slow handle on the left side of the receiver, which can be selected for semi-automatic or fully automatic shooting. The air conduction system adopts patented technology automatic adjustment of the air conduction hoop, so that the gun can also work normally on the bottom of the water or on the water surface. The aim is an irrelevant notched door and sight. The telescopic butt stock is made of steel wire. The most troublesome thing in the entire design of APS is the ammunition supply mechanism. In order to offset the influence of water, this rifle uses stainless steel arrows similar to javelins, and a slender bullet head to maximize the impact of water. This mps bullet is slender in shape, resulting in a wide front and rear dimensions of the magazine, which is very inconvenient to hold.

Underwater, it is definitely the world of Soviet frogmen! Whether the other party is a shark or a frogman from Western countries!

Kochakin prepared his APS assault rifle and went up to it. The current water depth is forty meters. His rifle needs to be within eleven meters before it can penetrate the diving suit of the opponent's frogman and cause fatal damage to them.

Since the water pressure differently generates resistance to warhead flight and bolt movement, the rate of fire and effective range underwater depends on the depth when used. (To be continued.
