In the military port of Country J's Neon Base, a Murasame-class destroyer was docked quietly in the sea.
On the deck, several SBU frogmen wearing black diving suits were conducting final tests and inspections on the scuba.
As early as 2009, when the Neon military went to the Gulf of Aden to perform escort missions, the two destroyers "Lien" and "May Rain" at that time were carrying members of the special guard force.
Since then, every batch of warships heading outside Aden has carried SBU members without interruption.
Inoue checked each of his five subordinates one by one to see if each scuba part was working properly.
There are generally two types of scuba used by special forces, one is open and the other is called closed-circuit rebreathers (CCR), but they are usually used in underwater special operations, especially infiltration operations.
It is a fully enclosed scuba.
Its advantages are long stealth time, large diving depth, and most importantly, the fully enclosed respirator does not produce bubbles, which can minimize the probability of being discovered.
On the deck side of the Kirisame, several sailors were putting several DPV small underwater propellers into the water.
This small underwater propeller was purchased from the Bald Eagle Military, and its supplier is STIDD Company.
The company was founded in 1991 and is headquartered in Twist. It has been engaged in the research and development of maritime equipment for special operations forces and is recognized as the most mature and reliable combat DPV on the market. Its customers include the Bald Eagle Navy and the special forces of more than 20 countries.
Troops, with total sales exceeding 400 units.
It is battery-driven. When carrying an additional load of 50 kilograms for two fully armed divers, the underwater speed is still more than 2.6 knots/hour. It is equipped with an RNAV underwater navigation system. RNAV includes a 20-channel GPS receiver to squeeze out every last bit.
Weak GPS signal to locate.
"Tonight, we must get the most detailed hull data of those ships. This operation must be successful and must not fail!"
After inspecting the equipment, Inosue began to encourage his men.
"After the failure of the last operation, I analyzed the loopholes in our operation. Why were we discovered? I don't think their sonar detection and underwater radar are powerful, but that our thrusters were too close, so we accidentally
We were discovered. Today we tried to park the propeller as far away as possible, and then used scuba to artificially approach the bottom of their ship. Everything should be as silent as possible. If we are careful enough, I don’t think they will notice that we are underwater.
"
"Hai!"
Several of his subordinates were splashed with chicken blood by Inoue, and their blood immediately rushed to their brains, feeling that they would be successful tonight.
"Set off!"
Inoue struck while the iron was hot, and with a wave of his hand, everyone slid down the rope ladder on the "Kirishima" to the water's surface, and plunged into the sea with a pop.
Soon, they found their own DPV thrusters in the water, and they formed three groups of two and slowly dived into the deep water.
The straight-line distance from Neon's base to the navy's base of a certain great power is about 8 kilometers, but if you sneak along the sea route from the dock of Neon base, it's not that far. They are both in the same bay, and the straight-line distance is only about 4,000 kilometers.
About meters.
Although the temperature in J country remains at a relatively high level all year round, the sea water temperature is still very low at night, and Inoue can still feel the cold feeling from the sea water through his thick diving suit.
Since it was night and at a depth of 15 meters, the visibility on the seabed was almost zero, so the entire operation relied on compass and GPS for positioning.
Fortunately, the diving depth is not too deep and the GPS signal is pretty good.
At this time, the lights in the neon base combat duty room were bright, and the technical sergeants and officers were all sitting in front of the command console. Commander Tanaka stared at the six light spots moving on the big screen - those were their frogman team.
The signal sent by the positioning device carried on the body.
Soon, Inoue's voice came from the earphones: "We have entered the warning range of the opponent's military port. Now reduce the speed, reduce the noise, and activate radio silence. Conduct the final test - test, test, test!"
"Received, the signal is good. Follow the original plan, now turn on radio silence."
Tanaka said the last words, and then asked a sergeant in charge of communications to cut off the communications, leaving only the GPS signal for tracking.
After all, the GPS signal is not very strong and is not easily detected underwater.
Standing in front of the big screen, watching the light spots approaching the military port of a certain big country, Tanaka Jun's eyebrows suddenly jumped a few times.
He couldn't help rubbing his eyebrows and wiping his eyes heavily to keep himself in the best condition.
However, his eyelids suddenly twitched a few times, and Tanaka felt inexplicably flustered.
An ominous thought passed through my mind.
…
Still 1,500 meters away from the military port, Inoue took out his underwater flashlight and turned it on and off three times to the right.
This is a signal.
On both sides of him, the three DPV underwater thrusters of the other teams shut down at the same time and stopped in place.
I looked at the depth gauge in the well and saw that the water depth here was 20 meters.
He held a flashlight and continued to type out a series of codes.
The three groups of frogmen left the propeller one after another, pulled out a steel cable from the head of the DPV propeller, and locked all the propellers on the seabed with anchor hooks.
After doing all this, the SBU team members took out various weapons and reconnaissance instruments from the thrusters. The instruments are mainly military structural scanners, which can conduct a full range of scans of the ship's bottom. There are also instruments that can analyze angles, approximate steel plate thickness, etc.
and other parameters.
There are also some sonar collectors, which can be placed on the bottom of the water to monitor the sound characteristics of ships passing nearby.
Because he learned the lesson from last time, Inoue chose to park the underwater propeller outside the port cordon this time.
It is said that the anti-frogman's radar and sonar scanning distance is not that far. If we can start to sneak there manually from here, we should be able to reach the designated location without anyone noticing and scan the detailed structural parameters of the bottom of the opponent's naval ship that just entered the port today.
.
This chapter is not over, please click on the next page to continue reading! This time, Inoue was much more careful than before. After all, he had learned from past mistakes. Last time he was only driven away by the opponent's sound and light means. As a Navy frogman, of course he understood that this was the opponent.
A relatively mild approach adopted by the Navy as it does not want to make things big.
However, we cannot give up the reconnaissance of ships because of one failure. You must know that the latest comprehensive supply ships and destroyers are included in this entry formation.
The data on these ships is very precious, and it is also very valuable military intelligence. You can get a scan of the bottom structure of the ship, and you can even analyze the characteristics of the navigation noise, so that future submarines from the sea can more accurately distinguish each other's models and can use these to identify each other's models.
Parameters to obtain more ship performance information.
After completing all the preparations, Inoue made a "forward" gesture to his men.
When the subordinates saw the waterproof lights drawing two circles in the darkness, they tacitly started to move one group after another, about ten meters apart, towards the port of the opponent's base.
Snorkeling 1,500 meters underwater requires a lot of physical strength, but with the help of the DPV small propeller, it can be said to be twice the result with half the effort.
The distance to the target was gradually shortening. Ino looked at the positioning device and his tense nerves gradually relaxed.
Because he didn't hear the sound of the speedboat maneuvering on the water.
As a rule, every military port will have speedboats on regular patrols and sentries at land barracks, which can effectively prevent infiltration and attacks.
The last time I sneaked to a place about 800 meters away, I encountered the opponent's patrol boat. Not long after, I was illuminated by a beam of light into the seabed, and I heard a shout, warning me not to approach the military restricted area.
Come to think of it, last time they were discovered by anti-frog sonar or radar, so a small team of the Chinese Navy came to expel them.
There was no movement this time, which meant that your method was effective and the other party didn't notice anything.
Suddenly, a gray object appeared in front of Inoue, blocking his entire line of sight.
"what?!"
Inoue quickly took out his flashlight and signaled to his team members to stop advancing.
In the darkness, the diving light illuminated a large seaweed-like thing about six meters ahead lying across the diving route.
