Seeing the sign language given by the other party, Zhou Hai, who knew the intention, nodded slightly to show that he understood and implemented it.

When the second rescue member sat back into the passenger seat, Zhou Hai, who was black and gray, was like a ghost in the deep sea, held the handrail and sat in the fourth seat of the No. 901 ‘Pufferfish’ underwater thruster, took out the seat belt and stuffed it into the metal buckle to connect and fix it.

After doing all this, Zhou Hai immediately raised his right hand to the driver who had been on standby, bent his index finger to form a circle with his thumb, and raised three fingers to confirm that the preparations were completed.

With Zhou Hai giving ready sign language, the driver on standby state immediately took action after obtaining the reception information and pushed the accelerator valve on his left hand to increase the power output.

"Buzz!"

In a blink of an eye, a slightly dull and sharp motor running sound came out, echoing in the surrounding sea water.

The high-performance fuel cell pack in the thruster is activated and continuously outputs a continuous stream of energy like flowing water to the integrated motor.

The high-performance integrated motor that obtains energy supply begins to operate, drives the annular pump to dictate the flow tube to rotate clockwise, and the propeller blade installed inside the metal pipe wall, which is as sharp as a knife, rotates slowly, from slow to fast, and constantly cuts the invisible sea water again and again to generate forward thrust.

The thrust has gradually increased from weak to steadily increase, and directly acts on the main body of the thruster, pushing the entire No. 901 ‘puffer fish’ forward.

The driver clasped the steering rudder and pushed forward gently, steadily controlling the No. 901 "Pufferfish" under him to change the angle, tilt and turn, turn around in a clever posture of 180 degrees, and then increase the power output power again to reach full load operation.

The second rescue team member and Zhou Hai held on to the same time to stabilize themselves.

"Buzz!"

The sound of the integrated motor is gradually rising. The ring pump deduces the flow tube rotating at the highest speed. Countless small and dense white bubbles float up from the nozzle of the flow tube, forming a white navigation track that looks like a wisdom tail, which is gorgeous and beautiful.

Accelerate and move forward.

After more than ten seconds, with the support of the shaftless pump thrust system in full load power operation, the No. 901 "Pufferfish" thruster, which has a very high acceleration compared to surface ships, easily reached its maximum speed of 30 knots per hour without any effort, and sailed straight to the 093G attack nuclear submarine that acted as a mothership, which acted as a mothership, without any effort.

"The acceleration is very high, maneuverable and agile, and there are three weapon hangers. I always feel that this thing is a bit related to the design concept of fighter jets, but the size is still too small to bear the high-intensity war needs, nor can it be used as a good weapon combat platform. I don't know if it will develop in the direction of underwater fighter jets in the future."

Sitting in seat No. 4, Zhou Hai held the metal handrail tightly with both hands to avoid being blown away by the oncoming strong sea water. The single-person diving equipment on his body resisted the impact of water pressure and high-speed navigation. He felt the surging power and characteristics of the underwater thruster under him, and started to think silently.

Think as a pilot.

With the latest fluid mechanics design researched by the National University of Defense Technology, the No. 901 ‘Pufferfish’ has extremely high underwater acceleration and maneuverability, and its comprehensive performance far exceeds that of the micro underwater thrusters served in various countries. In a sense, this can almost be called an underwater fighter.

Yes, underwater fighter!

In addition to high acceleration and maneuverability, as well as the two 5.8mm machine guns used for self-defense, the abdominal area of ​​the "Pufferfish" mini underwater thruster has a main hanging point and two secondary hanging points. If necessary, it can be used as a micro-weapon combat platform to carry a Fish-6 heavy torpedo and two short-range anti-submarine missiles, and undertake part of the anti-submarine and anti-ship combat missions.

Like a ghost in the deep sea, launch attacks from underwater, attacking enemy submarines and surface ships, and even aircraft carriers!

Of course, attacking an aircraft carrier is just a theoretical idea.

In reality, it is almost impossible for a "pufferfish" micro underwater thruster to break through the world's first navy's aircraft carrier battle group defense system.

Even if it has the world's lowest noise performance of 65 decibels, it is not possible.

Anti-submarine is always the best choice for the world's number one navy. In addition to sonar, the anti-submarine field can teach you how to be a human being.

Well, as for the aircraft carrier battle groups between Britain and France, I'm sorry, I just ignore them.

However, if the Navy really has the intention and idea to deeply explore and study the potential situation in the field of micro underwater thrusters, and truly transition it from the scope of micro underwater thrusters to - underwater fighter jets.

Then, the future maritime war will be even more interesting.

"It's a pity, I don't know how long it will take to develop to that level, so take it slowly."

Zhou Hai thought about his thoughts about puffer fish and underwater fighter jets, then shook his head gently, eliminated the distracting thoughts in his heart, and stopped thinking about it.

Underwater fighter jets, such cutting-edge weapons are too far away and somewhat unrealistic, and it is useless to think too much.

In the water, the No. 901 "Pufferfish" carrying three people advanced at a high speed. With its streamlined body like a shuttle, the frictional resistance generated by the thruster's contact with seawater during underwater navigation is minimized, and it is easy to tear the invisible and sticky seawater and head straight to the destination.

Extremely quiet.

Extremely fast.

After a while, the entire No. 901 "Pufferfish" sailed for more than 100 meters. After reaching a safe distance, the driver was familiar with the road and controlled the pump to dictate the flow tube to rotate counterclockwise, reverse and slow down, and faced the abdomen of the 093G attack nuclear submarine with a clever and elegant posture, just like a seal shuttled into the sea water.

Stable and accurate.

The driver of the rescue team continuously adjusted the angle and posture of the thruster, controlled No. 901 to come to the bottom of the lifesaving compartment, aimed at the cabin door, pressed the water cabinet switch button with his thumb, and opened the drain port of the left and right main water cabinets below the water line of the body to increase pressure, forcibly discharge sea water, and gain buoyancy.

The No. 901 ‘Pufferfish’ floated up smoothly, accurately crossed the metal hatch door, entered the submarine life capsule filled with sea water, and reconnected the metal fixed structure in the same cabin.

"Dong..."

With this slightly dull metal connection sound coming out, the high-definition camera installed in the lifesaving compartment faithfully recorded the video footage. Tonight's simulated boat boarding training was over and successfully passed.

The shaking of Zhou Hai's training results has been recorded and the timing has been suspended.

Time is frozen at 8:55 seconds.

Except for the ten minutes that Zhou Hai waited in the red float, the entire simulated boat boarding training process took only eight minutes and fifty-five seconds.

After doing all this and completing the parking action, the driver wearing bulletproof mirror raised his right hand to Zhou Hai, gave him a thumbs up, then put his five fingers together, pointed to the metal hatch door on the right, and signaled to go.

"call……"

Zhou Hai spit out a white bubble, nodded, raised his right hand, gave a thumbs up at the driver and the second rescue team member, and expressed his gratitude with etiquette.

The two of them shook their heads gently, and the bulletproof mirror contained a hint of respect.

Zhou Hai did not delay, smiled, then untied his seat belt, floated up and left the No. 4 seat of the puffer fish thruster, swam about two meters away, and came to the No. 1 cabin door of the lifesaving compartment, and opened the closed metal cabin door according to the standard operating procedures.

The cabin door opened, and the calm sea water surged again, pouring into it along the slightly narrow cabin door. After the sea water filled the internal space of the cabin No. 1 and the internal pressure reached equilibrium, Zhou Hai then went in and closed the door.

"drop!"

After Zhou Hai locked the cabin door, a red light flashed at the top of the not-so-large cabin, and a rapid and harsh alarm sound came out.

Immediately afterwards, the external drainage outlet of the cabin No. 1 opened, and the sea water filled with the internal space was quickly discharged, and the water surface was reduced at a speed visible to the naked eye.

After about thirty seconds, the sea water in the cabin was completely emptied, and there were still some water stains on the metal ground.

"Buzz!"

At this time, another metal hatch door in Cabin No. 1 opened.

A figure appeared.
Chapter completed!
