The next test was also very successful. The diving depth reached 400 meters, which was the result of Lin Dong's stopping. Although the thruster could still dive below 400 meters, but Lin Dong stopped it.

This is a civilian version of the underwater thruster. There is no need to dive as deep as it is. The current depth is enough.

Four hundred meters underwater was already pitch black. The two headlights of the underwater thruster and the luminous rods placed in front along the way made the 400-meter-deep seabed basically see clearly. The strange seabed species of all sizes appeared in front of everyone. They even glanced at the tentacles of a king squid flashed by, which scared the operator!

In fact, it is far from being seen in the thruster in the monitoring room, but even so, seeing it at the end, many people in the monitoring room were really eye-opening!

"When they come back, I must copy the surveillance video of the thruster and take a look!"

Although most of the people present were old military and shipbuilding technicians, there were really no ones who had been to the seabed, especially the seabed below 400 meters!

"I have to copy it too!" Another person smiled and said, "It looks so real. This is the real seabed. I used to see it on TV that it would be an infrared glimmer image when I saw it below a few hundred meters. It was really unhappy to see things in black and white!"

"Don't worry, when our real underwater luxury yacht is built, let's go down and have fun together!" Lin Dong said with a smile: "Don't be as complicated as scientific research, let's just treat it as an ordinary travel!"

Lin Dong said this, so he naturally had the confidence. He not only provided the military with technical information on the thruster, but also provided the thruster housing material formula, motor, battery, supporting pipelines and operating systems. Lai Tongguang had previously reported that the material formula was tested very successfully, resistant to high pressure and corrosion. Not to mention 400 meters underwater, even 1,000 meters underwater, it can also withstand water pressure. There will be no knots in the submarine shells that often appear in film and television programs due to excessive submersible cracks.

Just as the thruster was about to come back, Lin Dong asked for another test.

"I remember the technical information I gave was about the thruster carrying a float. Did you bring it here?"

"Take it with me!" Lai Tongguang nodded and said, "Two floats are ready for salvage."

"Then find a seabed about 200 meters deep and use a float to salvage something!" Lin Dong said: "Reefs are fine, just weigh about one ton. I remember that the thruster operating system has a complete automatic salvage program. Test it to see if it works!"

Lai Tongguang hesitated for a moment and whispered: "Mr. Lin, this system does exist, but it has not been tried in previous preliminary tests. I don't know if the operator can operate it proficiently..."

"It's okay, let them give it a try!" Lin Dong said with a smile: "It's better to be able to do it. If it doesn't work, let's modify it. This program is very important, and it is related to the positioning and function of our product in the future. It's best to test it this time."

What Lai Tongguang said actually exposed some problems. They must have tested it before, but the size is unclear, but they must have been launched. They have successfully conducted preliminary tests of speed and depth. Of course, they may just go into the water to see if there will be leakage, how the underwater propulsion will be progressed, etc.

Lai Tongguang nodded and said to the microphone: "The third test is carried out, and the last test. Swordfish, you can find a seabed within 200 meters and use a float to salvage a reef within one ton. This test must be operated automatically by the system. You must pay attention to it. If the situation is not correct, cancel the system task immediately and then come up!"

"Swordfish received!" After the operator answered, he began to move.

Because the thruster is fully automatic, there are only two operators inside. After receiving the instructions, they immediately float the thruster and reach a relatively flat sea area, and start looking for targets.

The situation on the seabed is very complicated. The complexity here is not the original submarine environment, but the seabed is full of broken fish nets, scrap tires, broken ships, iron tools and other garbage thrown by humans. It is difficult to see a flat and unpolluted seabed in the monitor of the thruster.

After searching for a long time, I saw garbage and didn’t see a reef of the right size at all. The people in the monitoring room were a little impatient. Lin Dong looked at it and suddenly picked up the microphone and said to the operator: “No need to look for reefs anymore, just the broken ship I just encountered!”

The picture flashed just now, and a small broken wooden fishing boat sank at the bottom of the sea, about a few meters long and wide, half of which was gone, half hidden in the sea sand.

When the thruster heard the instructions here, he immediately turned his head and headed towards the wrecked ship.

Soon, the thruster reached above the wreck. The operator immediately started the procedure and saw two floats stretching out under the thruster and connecting them with the thruster with steel cables and air pipes.

When the float arrived in front of the wreck, two mechanical arms stretched out from the propeller and began to dig around the wreck, digging away the mud and sand. The float also sprayed out the water flow and began to blow away the already messy mud and water.

Slowly, the wreck revealed the whole picture. The robotic arm began to pull out the rope to tie the wreck up, and then fixed the float to both sides of the wreck. It can be seen that the fixed position is very accurate, just at the stress point on both sides of the wreck, and there will be no loss of balance when floating up.

In order to ensure that the float can make the wreck float safely, three fixed steel pipes extend out between the two floats below the wreck to carry the wreck to ensure that the wreck will not fall apart during the float.

After all the fixes were made, the thruster began to recycle the steel cables. It was obvious that the thruster sank slightly downward, and then the power system started and began to rise slowly!

Soon, the thruster reached the sea surface and then dragged the wreck towards the dock!

Although the speed is not fast, it can be seen from the thruster monitor that the shipwreck is fixed very stably by two floats!

There are many people in the dock, and some people are already waiting in a hurry. The original test was only half an hour, but forty minutes have passed. The thruster has not come back yet. Some people are worried that the thruster will not break, right?

"Here's here!" Someone was sharp-eyed and soon saw the thruster slowly coming over the sea.

"Why did it come from the sea? Could it be that there would be no malfunction?"

"That's right, this speed is slow enough. I remember when I was promoting it, didn't it say that it could reach seventy or eighty knots underwater? Why is it slower on the sea?"

"What are you talking nonsense?" Someone already knew the situation. "That's the thruster dragging things! It is said that it was testing the salvage function of the thruster, and a broken fishing boat was fished out under the water!"

Can this still be done?
