【Chapter 185】Floating

The "Thunder Dragon" successfully jammed the woI-7w unmanned reconnaissance aircraft of the m army and caused it to crash to the sea level, and the Xia military immediately called Major Zhao, and Major Zhao replied very calmly: "Yes, this is."

One of the improved parts of the "Thunder" can simulate the input signal of the drone, so that it can be used in a short time

Signal control of the Thunder analogue ................ Yes, after all, the fault party for this invasion of our territorial waters is on the M side, and I don't think this kind of slightly drastic countermeasures are serious, huh.................... Okay, I'll make adjustments. Du Jin seemed to hear something unusual

After all, there are many angles and directions considered at the national level, and it is understandable to rely on an intrusion of the sea area to conduct reconnaissance and drive away, but if the woI-7w unmanned reconnaissance aircraft is directly taken down, then it is naturally impossible for country m to leave any leeway, and it is better to rely on diplomatic risks to ensure that Xia country cannot get the wreckage of the woI-7w unmanned reconnaissance aircraft for research and reverse replication.

At this time, Xiao Ai suddenly said to Du Jin: "Master, I'm there."

A medium-sized underwater vessel belonging to country M was found near the "Thunder", and its design was so bad that it seems to be called a submarine. ”

"Submarines?" Du Jin immediately felt that things had taken a turn for the better, and he immediately asked rhetorically: "Xiao Ai, where did you get this information, is this submarine a conventional attack submarine or a nuclear-powered submarine?" He almost immediately ruled out passing

After all, the submarine is very difficult to detect by radar and visible light, and even if it is sonar, there is a lot of gratuitousness, after all, it is really difficult to distinguish between fish and submarines most of the time, and now the mainstream method is anti-submarine helicopters for close observation.

As a matter of fact, antisubmarine warfare is the most complicated kind of high-tech warfare, which requires the comprehensive cooperation of all arms of the navy, and cannot rely only on antisubmarine aircraft; under normal circumstances, antisubmarine aircraft are only suitable for general investigation and deterrence in a wide range of sea areas.

The process is roughly as follows: First, the reconnaissance sea area and route are demarcated, a sonar buoy is dropped every other section of the extended route, the airdrop density is calculated according to the actual situation, and the airborne radar can be used in the hope of discovering the submarine's periscope or snorkel.

If necessary, it will need to be deployed in large quantities in the anti-submarine high-risk sea area, because the sonar buoy can work actively and passively, and the advanced digital sonar will feed back the detection situation to the sonar crew, and if an abnormality is found, the anti-submarine machine will return to the area where the buoy is located and throw a large number of sonar buoys according to the triangulation method and use a magnetic field detector to accurately locate the submarine.

After positioning, you can use deep bombs or anti-submarine torpedoes to attack dives. Moreover, in the case of insufficient ammunition or sonar buoys, other anti-submarine units can be recruited to support.

The large-area search efficiency of aviation anti-submarine is high but the success rate of capture is low, and this really depends on luck, if the submarine is in a low-speed quiet or even stationary state, it is difficult to be discovered, and modern submarines can even use the ocean current to float or sit on the bottom to use the submarine terrain to avoid the detection of active sonar and synthetic aperture radar, and the general anti-submarine aircraft can only get a little rough information after an average of more than a dozen sorties, so it still relies on the intelligence cooperation of surface ships, their own submarines and submarine sonar base arrays.

Therefore, Du Jin didn't want to use it

The hand of the "Xiaolong" said the existence of this submarine, and after thinking for a while, he still decided not to let go of the submarine that did not know the purpose and left, of course, the main thing was that he was afraid that Major Zhao would receive some involvement, after all, the other party was influenced by Du Jin to make the decision to interfere and make the drone fall, he did not treat Major Zhao as a one-time

"Tool man", this is inconsistent with Du Jin's nature, not to mention, Du Jin can now count on Major Zhao to notify the upper echelons to solve the matter of Wen Song, if the time is delayed because of the transfer, then Du Jin will really lose more than he gains.

Thinking of this, Du Jincai asked Xiao Ai: "Xiao Ai, can you use the military communication system of country M to make this submarine float in a short time?" Or let it emit some signals that are easy to capture? Provided that the people of that submarine do not find out that this is a forged order. "Since Du Jin can't let it

"Thunder Dragon" took the initiative to discover the existence of this submarine, so he started from the submarine itself, let

The Thunder passively spotted him, after all, the submarine is the most difficult to accurately capture1 because it is in the depths of the ocean, making the radar almost ineffective, and even the sonar has been destroyed by other marine life

The chance of "cover-up", but if it comes to the surface on its own initiative, then the submarine is like a turtle with a turtle shell removed, no different from a fishing boat that has no close-range counterattack ability.

"Master, woo.............. It is no problem to obtain the safety certificate of the M side through special means to the submarine in this area, and just now Xiao Ai determined the name of this ship by retrieving the information source of the specific M party in the designated area

The location of the underwater ship of the "submarine", but if it is to convey the information of the specified order, due to the speed limit of the world's communication technology, Xiao Ai needs to spend 2-3 minutes to deal with it, it is definitely not that Xiao Ai's own ability is not enough."

"That means you can only convey some vague orders." Du Jin immediately understood what Xiao Ai meant, Xiao Ai is now like a computer with a high U and a low display, even if her own ability is far beyond the present world, but she is helplessly limited by the signal base of various basic equipment in reality, which Du Jin has long been mentally prepared, and after thinking about it a little, he told Xiao Ai that he wanted to send a short signal.

...............................

"Oh God, there's still no news from the Air Force?" A sailor who looked at the operation console in the Fillmore submarine complained that they can now be in the waters of Xia Kingdom, although the Fillmore submarine they are in is only a conventional torpedo boat converted from a scientific research submarine, but no matter how it is said that it is also a combat boat belonging to the naval sequence, if they stay too long and are discovered by Xia Guo's anti-submarine system, then their fate will be very tragic, even if they are not blown to pieces by Xia Guo's counterattack, after being captured, according to the urine nature of M country, they will be said to be defector-fleeing soldiers, It is almost impossible to get bail back to China.

"Hey, Birrell, don't be so nervous, our mission is not to fight with the navy of the Xia Kingdom, after completing the recovery assistance mission, we can dive deep enough to leave, even if those people in the air force fail, we will not be at risk."

"But............" A sailor on the other side of the console stood up and stretched, casually dismissed the sailor's words and said: "My brother, you are so nervous will only make your deep-sea fear intensify, think about the allowance for our trip back, think more about which girl the money will spend on the most valuable in the future, now think about it so much, you ..........." Before he finished speaking, an indicator light flashed on the console, which is the application procedure for external signal access.

"Haha, look, I said we won't wait too long, Birel, you go and call the first mate, I'll verify."

"Okay." Then the remaining soldier sat down to review the source of the signal, the key and the security code, although he looked a little frivolous and arrogant, but he was very meticulous and serious in his work, but he was destined not to find anything, after all, the key attached by Xiao Ai was not forged, but was indeed obtained from the command system of the Navy of Country M, but not through the formal approval process............... Moments later, a man in a white military uniform followed Private Birrell into the intelligence cabin, and by this time the sailor had completed his approval, and handed the printed command message to the man with a high rank, who looked down: "Target accomplished, recovered, evacuated, avoided encounter, 172-584-74." The officer's eyes were slightly condensed, this order seemed a little irregular in his opinion, after all, he didn't even show the details of the mission, just explained the results and processes, but he just felt a little strange, and didn't suspect anything, after all, it was an order that passed layers of security tests, if this can be faked, then the other party can directly launch a submarine-launched missile to send himself to the sky according to the recognized submarine sonic characteristics, instead of playing word games here, not to mention that it is now in the territorial waters of the Xia Kingdom, This officer can also understand that in order to avoid the long-term, large-capacity signal transmission being discovered by Xia Guo, it is understandable that he deliberately streamlined it.

Subsequently, the order was handed over to the captain of the submarine through the hand of the first mate, that is, the person in charge, and the captain with vicissitudes and a serious look on his face looked at the content of the order, and finally carried it out absolutely, but after all, he was a naval officer with more than ten years of experience and qualifications, and he did not recklessly go directly to the position close to the water, but ordered: "Go to the 172-584-74 target, float 300 meters after arrival, first detect by releasing the detection robot, and ensure that there are no surface ships to ambush, There is no problem to rise to fifty meters below sea level, and the periscope system ensures that no attack helicopters appear! Finally, radar detection is carried out on the surface to quickly recover the target and detect incoming enemy aircraft nearby. "And submarine equipment as an underwater giant, because it has to swim in the depths of the world's oceans for a long time, is very airtight, and if there is no complete detection and perception system, it will be completely done

The "underwater blind" is simply unable to detect, search, and track underwater and water targets, and even to avoid danger and launch attacks.

This equipment was assembled almost not long after the submarine was assembled, and the early periscope only had an optical observation function, that is, the principle of optical reflection was used to install lenses at both ends of a long tube, and the upper lenses reflected the image downward; The bottom lens will reflect the image for the second time, and the observer can see the image of the upper mirror facing the direction through the mirror at the bottom, and the periscope of the modern submarine has been electronic, replacing the optical path with a camera and cable, in addition to visible light, infrared rays can also be observed, and there are antennas on the mirror body for communication and detection of enemy radar signals, and the volume has also been reduced a lot.

If it is impossible to use a periscope, it is necessary to detect various underwater targets mainly with the help of sonar, the most well-known system, which is an electronic device that uses the propagation characteristics of sound waves under water to complete underwater detection and communication tasks through electro-acoustic conversion and information processing.

The sonar system can be roughly divided into two types: active sonar can send out an acoustic signal by itself, and use the changes reflected back after the signal encounters an object to calculate the relative orientation and distance of the object; Passive sonar is actually a listening device, which does not emit any sound signals, but only receives various sound signals from the surroundings to judge and identify different objects.

Of course, if the difference between the two is easy to understand, relatively speaking, the former is easy to expose its own tracks, the latter is easy to stealth, and there is even a risk of accidental collision when two submarines in silent mode meet, of course, this risk is generally low, unless it is a submarine cluster.

In addition to periscopes and sonar, submarines can also conduct target reconnaissance with the help of electronic equipment such as radar. Radar can detect sea surface targets in a periscope state, mainly provide target data for torpedo or submarine missile attacks, and can also be used for navigation and sea search.

Compared with periscopes, submarine radars have the advantages of high ranging accuracy, long detection distance, short measurement time, and all-weather operation.

However, the radar works in the active mode, and the antenna needs to rise to a certain height above the sea surface, which has a great impact on the concealment of the submarine, and the timing of use must be strictly controlled.

I have to say that this captain is definitely an old fritter, if it is an ordinary ambush, there is no way to deceive him, even if he forges the order through a special way, he will be discovered by his cautious advance deployment, but unfortunately, his measures have no impact on Du Jin, after all, Du Jin's goal is not to sink the submarine, but just to let it

It is enough for "Xiaolong" to discover this submarine through detection, so that Major Zhao will not only not be affected by his previous behavior, but will even accumulate the next unexpected tool, which can be regarded as another gift from Du Jin to thank him for helping him........................

"Sir, the sonar and detection robots have not found a target, and they are floating............. No targets were found at Periscope 3......... Having reached a depth of 20 meters below sea level, sir, is it ready to activate the radar for detection of enemy aircraft. And just after the radar detection device was deployed, the sailor of the previous intelligence cabin hurriedly ran to the door of the wheelhouse, knocked on the closed sealed hatch, as if there was something very urgent, the first mate asked several soldiers on the side to be vigilant, and then sent an adjutant to open the door, as soon as the sealed hatch was opened, the sailor shouted: "Captain, that order is fake, we have been fooled!! ”

"What's fake?!" The captain asked a little loudly, and then immediately stepped forward and snatched the order sheet from the other party's hand and saw it: "The mission fails, immediately go to the 172-584-65 area to recover our drone, and evacuate immediately after completion!" ”

"Damn! Dive now, dive now! After reading the above text, the captain immediately shouted to the operator on the side, if an anti-submarine missile is launched at this time, then their submarine will be hit 100%, after all, the speed of the dive is definitely not as fast as the instantaneous burst shock wave of the missile hit.

And at this time

The "Thunder" has already collected all of this submarine

In the "eyes", the specification data and parameters of this submarine were detected by it, and when the captain found an abnormal emergency dive, he directly controlled it

The Xia Air Force, which observed the "Thunder Dragon", had confirmed with the Navy that there were no submarines of its own in that area, and there were no licensed submarines working in the area

Judging from the high-definition detection images transmitted back by the "Thunder", there may be equipment similar to torpedo launchers on the submarine.

At this time, Major Zhao, who was with Du Jin, received another phone call, but the content was completely different from the words of the slight reprimand just now, and before affirming the correctness and decisiveness of his decision, he hung up the phone and handed the special signal acceptance desk in his hand to the adjutant of a piece, Major Zhao looked at Du Jin with a rare smile on his tense face, he didn't know that this submarine was made to float by Du Jin and was observed, but in his consciousness, if there was no persuasion from Du Jin before, Major Zhao wouldn't necessarily make the decision to take control of that enemy drone, and now, he's clearly made the right bet.

"Comrade Du Jin, thank you for your suggestion just now, don't worry! I'll talk about the theft of your technical papers, I'll see you later

After the finishing task of the "Thunder Dragon", I immediately set off to go to the upper echelons to react in person, and I will notify the captain of the division as soon as there is news, please rest assured that you and the captain of the division! Du Jin nodded with a smile, Si Qing on the side seemed to have guessed something, but she couldn't figure out how Du Jin was involved in this matter, even if Si Qing's sixth sense strongly hinted

"Du Jin is the main reason why this submarine was discovered by our side", but she didn't know the existence of Xiao Ai, so it was naturally impossible to guess the process, but she heard Major Zhao solemnly promise herself and Du Jin again, instead of being a little uncertain as before

"Hint", which also relieved her. The subsequent recovery of the wreckage is still a diplomatic problem of the Xia Kingdom, and it has nothing to do with Du Jin's research institute.

After the "Xiaolong" sent fighters and unmanned attack aircraft to the Air Force, it completed the mission and began to return, and Si Qing and Du Jin were also sent back to the school, but before leaving, Du Jin also added to Major Zhao: "By the way, Major Zhao, I still have a little bit to say about that technology, in addition to the complete test preparation, I have a certain scale of practical foundation for large-scale mass production, I hope you can convey it to me by the way." ”

"Large-scale mass production?!" This made Major Zhao a little surprised, after all, test preparation and large-scale mass production are not a level of things, to be precise, the small test refers to the theoretical research results of the laboratory, the preliminary amplification, production under the conditions of the laboratory, the pilot test is to make the research results industrialized, reduce the risk of transformation, improve the conversion rate, the scale-up trial production.

In addition to the scale, other conditions are basically the same as normal production, which is a necessary transition link from small-scale experiments, pilot tests to industrial production.

In fact, before the small test, they have already experienced theoretical research in the laboratory, that is, the reaction verification was carried out with containers and tools such as beakers, measuring cups, heating utensils, glass rods, etc.

The small test is a preliminary amplification on the basis of theory, and its main responsibility is to complete continuous production, from feeding to transferring to receiving, which is a complete continuous process.

Pilot test is a confirmatory test done under the premise of the success of the small test, mainly to verify the feasibility of material transportation, the corrosion resistance of equipment and pipeline materials, the recyclability of raw materials and solvents, etc., in addition to the different scales, the biggest difference between it and the small test is the source of raw materials, one is a chemical reagent, one is an industrial-grade raw material, after all, the cost and synthesis difficulty of the former is very high, mainly in terms of performance, resistance and stability, while industrial raw materials are based on cost as the primary consideration.

As for the difference between large-scale production and mass production mentioned by Du Jin, there is still a big difference, and when it comes to the mass production stage, the problems to be solved are mainly market-oriented problems, that is, the problems of production efficiency, energy consumption, the recycling and treatment of the three wastes, and the guarantee of safe production.

In addition to the difference in scale, the biggest difference between it and the pilot test is that the focus of the problem to be solved is different, one is technical, the other is economic, of course, the economic problem may also contain the problem that needs to be solved by technology.

Although Du Jin can find the technology of rapid practice and mass production in the information and blueprint provided by Xiao Ai, market and economic factors make him unable to take it out too directly, even if Xiao Ai can completely control almost 90% of the financial management system on Blue Star, but the impact of this control is probably not much smaller than that of nuclear warfare, so Du Jin is still ready to seek stability and gradual progress..............

"I see! I'll pass it on to you! Du Jin nodded, and then followed Si Qing, just when Du Jin and Si Qing sat down to send them back, a phone rang on Si Qing's mobile phone, and she saw this string of numbers, there was obviously a disgusted and helpless expression on her face, her finger hung above the screen, and she didn't click it for a long time, as if this phone call was a life talisman, Du Jin looked at Si Qing's abnormal reaction, and seemed to guess something.
