Ballistic Silence of Special Years

That night, one o'clock in the morning.

In the naval port of the Neon Base of Country J, a Murasame-class destroyer docked quietly in the sea.

On deck, several SBU frogmen in black wetsuits are performing final tests and checks on the scuba.

As early as 2009, when the Neon military went to the Gulf of Aden to perform escort missions, the two destroyers "Lian" and "May Rain" at that time carried members of the special security team.

Since then, every batch of warships going out of Aden has carried SBU members, and the period has not been interrupted.

Inoue checked each of the scuba parts for his five subordinates one by one to see if they could work normally.

There are generally two types of scuba used by special forces, one is open and the other is called closed-circuit rebreathers-CCR, but it is usually used in underwater special operations, especially infiltration operations The most is a fully enclosed scuba.

Its advantage is that it has a long sneak time and a large dive depth. The most important thing is that the fully enclosed respirator does not produce air bubbles, which can minimize the probability of being discovered.

On the side of the deck of the "Kiryu", several sailors are putting several DPV small underwater thrusters into the water.

This small underwater propeller was purchased by the Bald Eagle military, and its supplier is STIDD.

Founded in 1991 and headquartered in Twisting, the company has been engaged in the research and development of marine equipment for special forces. It is recognized as the most mature and reliable combat DPV in the market, and its customers include the Bald Eagle Navy and special forces in more than 20 countries. Troops, total sales exceeded 400 units.

It is powered by batteries. When carrying two fully armed divers + 50 kg of additional load, the underwater speed still exceeds 2.6 knots/hour. It is equipped with an RNAV underwater navigation system. RNAV includes a 20-channel GPS receiver to squeeze the last A little weak GPS signal to locate.

"Tonight, we must obtain the most detailed hull data of those ships. This operation must be successful and must not fail!"

After checking the equipment, Inoue began to cheer for his subordinates.

"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 good or bad, but our propellers are too close to accidentally We were spotted. Today we try to stop the thrusters as far away as possible, and then use scuba to artificially approach the bottom of their ship. Everything must be as silent as possible. If we are careful enough, I don't think they will find that we are underwater. "

"Hay!"

Several subordinates were splashed with chicken blood by Inoue, and their blood rushed to their brains immediately, feeling that tonight must be a success.

"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 surface of the water, plopping into the sea.

Soon, they found their DPV propellers in the water, and they were divided into two groups, a total of three groups, and slowly dived into the deep water area.

The straight-line distance from the base of Neon to the base of a certain big country’s navy is about 8 kilometers, but if you sneak along the sea route at the pier of the Neon base, it is not that far away. They are all in the same bay, and the straight-line distance is only about 4000 meters. about.

Although the temperature in country J is maintained at a relatively high level throughout the year, the seawater temperature at night is still very low, and Inoue can still feel the coldness of the seawater through his thick diving suit.

Since it was nighttime, and at a depth of 15 meters, the visibility of the seabed was almost zero, so the entire operation relied on compass and GPS for positioning.

Fortunately, the dive depth is not too deep, and the GPS signal is not bad.

At this time, the combat duty room of the neon base was brightly lit. Technical sergeants and officers were sitting in front of the command console. Commander Tanaka was staring at the six moving light spots on the big screen—that was their frogman team. The signal from the positioning device carried on the body.

Soon, Inoue's voice came from the earphones: "We have entered the security 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. Execute as originally planned, and now turn on radio silence."

Tanaka said the last sentence, and then asked a sergeant in charge of communication to cut off the communication, keeping only the GPS signal for tracking.

After all, the GPS signal is not strong enough to be detected underwater.

Standing in front of the big screen, watching the light spots gradually approaching the military port of a certain big country, Jun Tanaka's eyebrows suddenly jumped a few times.

He couldn't help but rubbed between his brows and wiped his eyes heavily to keep himself in the best condition.

However, the eyelids suddenly twitched a few times, and Tanaka felt flustered for no reason.

An ominous thought crossed his mind.

……

At a distance of 1500 meters from the military port, Inoue took out the underwater flashlight and turned it on and off to the right three times in succession.

This is a signal.

On both sides of him, the three DPV underwater thrusters of the rest of the team shut down at the same time and stopped in place.

Inoue glanced at the depth gauge. The water depth here was 20 meters.

Holding the flashlight, he continued to type a series of codes.

The frogmen of the three groups 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 finishing all this, the SBU team took out various weapons and reconnaissance instruments from the thrusters. The instruments are mainly military structural scanners, which can scan the bottom of the ship in all directions, and 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 cordon of the port area this time.

Ordinarily, the scanning distance of the anti-frogmen's radar and sonar is not that far away. If we can start artificially sneaking 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 time, Inoue was much more careful than before. After all, he had learned from the past. Last time, he was only expelled by the opponent's sound and light means. As a navy frogman, he certainly understood that this was a relatively gentle way that the opponent's navy did not want to make matters worse. means.

However, the reconnaissance of ships cannot be given up because of a failure. You must know that there are the latest comprehensive supply ships and destroyers in the formation entering the port this time.

The data of these ships is very precious, and it is also very valuable military intelligence. You can get the scan chart of the bottom structure of the ship, and even analyze the characteristics of the navigation noise, so that the submarines from the sea can be more accurate when distinguishing the opponent's model and can be based on these. parameter to get more information about ship performance.

After finishing all the preparations, Inoue made a "forward" gesture to his subordinates.

After seeing the waterproof lights drawing two circles in the dark, the subordinates tacitly began to move one group after another, with an interval of about ten meters, heading towards the port of the opponent's base.

Swimming 1500 meters underwater requires a lot of physical strength, but with the help of DPV small propellers, it can be said to be more effective.

The distance to the target was gradually shortening, Inoue 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.

According to the usual practice, every military port will have speedboats to conduct regular patrols, and send sentries to the land barracks together, which can effectively prevent infiltration and sabotage.

The last time I sneaked to a distance of about 800 meters, I encountered the other party's patrol boat. Not long after, I was illuminated by a beam of light into the bottom of the sea, and heard shouts, warning myself not to approach the military restricted area.

Come to think of it, the last time it was discovered by the anti-frogmen sonar or radar, that's why the Huaxia Navy team came to expel it.

There was no movement this time, which showed that his method was effective, and the other party didn't find anything.

Suddenly, a gray object appeared in front of Inoue, blocking the entire line of sight.

"what?!"

Inoue quickly took out his flashlight and signaled to the team members to stop advancing.

In the darkness, the diving lights illuminated a large piece of seaweed-like thing lying on the sneaking route about six meters ahead. (end of this chapter)
