The number of months! On the same day, as soon as night fell, the 1st Fleet entered the battlefield of naval warfare north of the Yap Islands along the "safe corridor" opened up by the air force and attack submarines south of Guam. It was at this time that the First Pilot Fleet received the last piece of tactical information related to the First Main Fleet.

According to this intelligence provided by the US military reconnaissance plane. Battlefield time. The 1st Main Fleet is still about a kilometer north of the Yap Islands, patrolling back and forth on typical anti-submarine and anti-submarine routes, with no signs of heading south to the Yap Islands or eastward into Guam. It's just that as night falls, the reconnaissance planes can no longer track and monitor the First Main Fleet, to be precise. It is impossible to track and monitor 8 "Qin"-class capital ships at night.

This objective fact must be accepted by the commander of the first fleet, whether he likes it or not.

As mentioned earlier, the 1st Main Fleet did not leave the covered area of the naval aviation of the republic. In the stratosphere, which is about four to a kilometer behind, there are at least a brigade of short patrols on standby. Affected by this, none of the US reconnaissance planes that went to search for and monitor the First Main Force Fleet dared to use active detection equipment. Prior to this, more than eighty percent of the nearly 100 reconnaissance planes lost by the US Navy were shot down by fighters of the Republic Navy because their whereabouts were exposed using active detection equipment. With the arrival of the 1st Main Fleet in the pre-selected decisive battle area north of the Yap Islands and its combat platooning patrol, the US Navy could only dispatch heavy fighters carrying reconnaissance equipment to carry out reconnaissance missions. Although the survival rate of "combat reconnaissance planes" when intercepted is much higher than that of reconnaissance planes converted from maritime patrol planes and large transport planes, the combat performance of the clown has long been proven, and the US Navy does not have a kind of air supremacy fighter that can compete with it for the time being. In addition, the patrol area of the clown group extends to the rear of the first main fleet, and for fighters flying above the "Mach," the distance of a kilometer is nothing more than a matter of minutes, so the US Navy's "combat reconnaissance planes" can only use passive detection equipment, and do not dare to rashly use active detection equipment such as fire control radar.

Admittedly, the shape is "sci-fi." The stealth capabilities of the capital ships of the "Qin" class are very prominent. As the first to adopt the abnormal design idea, that is, the active stealth ability is no longer used as the main indicator, and the passive stealth ability is once again mentioned to the large warship in the key position, the very streamlined shape is the direct embodiment of the "Qin" class passive stealth ability. This design idea also emerged in response to various passive detection systems, especially long-range warning radars that work completely in a passive manner, after all, all active stealth measures are electronic interference of a specific nature, which will definitely release radio waves. It is also easy to be detected by passive detection systems.

In addition to improving radar stealth capabilities by improving the shape design, "Qin. It also uses various means to improve spectral stealth capabilities, especially infrared and ultraviolet stealth capabilities. For example, in order to improve the infrared stealth ability, "Qin." The latest energy system is adopted, and the power conversion rate, that is, the ratio of the output power of the power supply to the output power of the controllable fusion reactor, has been increased from less than the previous to a small amount, which is equivalent to an increase in pus. Although the cost of doing so is extremely high, i.e. the individual power of the energy system is reduced by more than the eye, i.e. with the same output power. The quality of the energy system has been more than doubled, but the benefits brought by this are also very obvious, that is, the overall thermal radiation intensity of the battleship has been reduced by more than eighty percent, plus the sprinkler cooling system covering the entire battleship, "Qin." The level of thermal radiation can be controlled at the level of background radiation, even if it is reached. Before feeding, the radiation intensity is only higher than the background radiation of the gills to, Anhui, and "Qin." The level of thermal radiation of other large warships before the class was in the background of the billet to the Wei between. For large warships such as aircraft carriers, which cannot be equipped with an integral sprinkler system, the level of thermal radiation is even higher than that of the background. Theoretically, the level of thermal radiation drops by a hundredth. The distance now from the infrared detection equipment will be shortened, that is, by two-thirds. From this, it can be roughly deduced that the infrared detection equipment on the US military reconnaissance plane has a positive impact on the "Qin." The maximum present distance of the class will not exceed 1,000 kilometers, and before that, the passive detection system on the "Qin" class will certainly be able to display the US military reconnaissance plane. And call for anti-aircraft cover.

In a sense, the "Qin" class is equipped with only 6 electromagnetic guns with the standard displacement of Wanghui Koutun, and there is no second attack weapon, in addition to the high trust of the Republic Navy in the new electromagnetic gun, it also has a lot to do with its design concept of overemphasizing passive stealth. Conservative estimates. In addition to the hull, the standard displacement of Wangsitun also includes the living materials of all officers and soldiers, the personal belongings of officers and soldiers, and the ammunition equipped according to two-thirds of the combat base, etc., in addition to the hull, which is related to the passive stealth design, which accounts for about half of the total combat displacement, and the mass of the hull generally accounts for about half of the standard displacement. If you follow the traditional design concept, that is, emphasize active stealth capabilities. Enhancing passive stealth only when conditions are available can control this ratio around the gills. In other words, if the excess mass is used on the weapon system, the weapon system allocation rate of the "Qin" class will be excessive, reaching a level comparable to that of a cruiser.

During the day, US reconnaissance planes can also track and monitor the First Main Fleet with a passive detection system operating in the visible light band. Although visible light stealth technology has long been proposed, but the pure visible light stealth technology is still far from the point of mature use, the so-called visible light stealth technology, in fact, is a visual deception technology, like a chameleon, by blending into the background to deceive the enemy, rather than in a completely transparent way to avoid reflecting and refracting visible light. This kind of background deception technique is not bad for the human eye, but it is impossible to fool a high-performance computer. In any case, it is certainly much easier for a reconnaissance plane flying at an altitude of several tens of kilometers to present a fleet in a specific sea area than a reconnaissance plane that is currently 100 kilometers away, so the visible light detection equipment supported by a computer-aided system is the most reliable, the most valued, and the most commonly used passive detection equipment.

The problem is that at night, the efficiency of visible light detection equipment will be greatly reduced

From the theory; Even in the dark night when you can't see your fingers. Still not absolutely dark. The problem is that after the signal enhancement processing of the image, it will definitely be distorted, and this subtle deviation will be magnified several times, or even dozens of times with the detection distance of hundreds of kilometers, so that the image is blurred so that the computer can not identify the target from it, which also makes the detection system lose its ability to work.

Although the error can be effectively reduced by shortening the reconnaissance distance, that is, by reducing the magnification of the image, it was mentioned earlier that at a sufficiently close distance, "Qin. The passive detection system can spot US reconnaissance planes and call nearby air defense fighters to intercept them.

It can be seen that in. Day and night, the US reconnaissance planes were still able to detect the escort warships in the First Main Fleet, but they could not continue to track the eight "Qin." class capital ship.

Although there are still quite a few US attack submarines searching for and tracking the First Main Fleet near the battlefield, the passive sonar on these submarines can appear at an altitude of hundreds of kilometers away and are surface ships. And it is precisely positioned at about 4 kilometers. But none of the passive sonars were able to turn off the main propulsion system, and with the help of the wave-following control system, a large warship floating on the surface of the sea.

You must know that before the outbreak of the Great War, there were dozens of ship collisions on the high seas between the Navy of the Republic and the US Navy. The vast majority of these collisions were between a large warship that was tracked and a submarine that was approaching at a high level and trying to probe the surface at periscope depth, and the main cause of these collisions was that the submarine's passive sonar was difficult to turn off the main thruster, and the large warship was controlled by the wave-following control system. That is, if the commander of the first main fleet is willing, he will be able to make 8 "Qin" ships after nightfall. The capital ships of the class broke out of formation. Although this is very risky, because by dawn, the US reconnaissance planes can come in handy again, and the capital ships without the cover of escort warships are not only vulnerable to air attacks. It is also more vulnerable to attacks from below the surface. However, there are many fleets and fleets of the Republic Navy in the vicinity of this area, for example, less than a kilometer to the north, which is the main route from Naha to Saipan, and on this route, several fleets and fleets shuttle back and forth at any time. In this way, the First Main Force will have more options and a great opportunity to use misinformation to lead the US military down the wrong path.

If it had been 2 days ago, it would have been nothing.

In any case, the US intelligence agencies have proved that the effective range of the new electromagnetic guns on the "Qin" class in naval combat is about 1,000 kilometers, and the farthest distance will not be exceeded. kilometers or more. Because "Qin." The class is not equipped with other long-range attack weapons, so as long as the distance is kept at a distance of more than 1000 kilometers, the first fleet does not need to consider the number of ships from 8 "Qin. class capital ship threat. Although in the first main fleet, there are also anti-aircraft cruisers with the same number of capital ships, as many multipurpose destroyers, and as many as old anti-submarine ships, including 8 anti-submarine destroyers and 8 anti-submarine frigates, and these warships are basically capable of carrying an ugly range. kilometers of cruise missiles, but it is common sense to infer that the main task of these warships is to cover the female capital ship, so the main ammunition they carry is regional anti-aircraft missiles, not anti-ship missiles and cruise missiles. More importantly, these ships are all under the supervision of US reconnaissance planes, and as long as they fire missiles, they will be spotted, so there is no possibility of a surprise attack on the First Pilot Fleet.

As the First Fleet entered the waters west of the Mariana Islands, it was getting closer and closer to the decisive battlefield. The commander of the US army had to focus on the eight ships from the "Qin." class capital ship threat.

Of course, the US commanders are still confident in the performance of the "Long Beach" class.

As a capital ship, the weapon of choice must be a large-caliber electromagnetic gun. Although the eight Long Beach-class ships were delivered to the United States Navy without full testing after completion and departed from New Orleans after the arrival of the fleet officers and men, it was only while passing through Puerto Rico that the maximum range of the new electromagnetic cannon was tested with the help of a naval range about a kilometer from Puerto Rico on the island of Roncador in the western Caribbean Sea, and the minimum diameter of the gill ammunition dispersal range at the maximum range. Although all the performance reached the design index, and some of them exceeded the design index, the commander of the US military was not the first fleet at that time and did not know it. This time-consuming and laborious test caused the fleet to spend several hours replenishing ammunition when it arrived in Panama, and it was this delay that caused it. Let the small reconnaissance satellites of the Republican Space Force reveal the whereabouts of the American fleet.

In any case, the main guns of the "Long Beach" class are really good enough. According to the design indicators of the US Navy, when using weigh-class ammunition, the maximum firing range should not be less than the old 4,000 meters, and the effective firing range is determined by the actual situation, that is, in the case of the ship's independent operation, it should not be less than concave 1,000 kilometers, and in the case of intelligence support, it should be over, and it is best to achieve it. Of course, this was named by the U.S. military, apostrophe, taming. , the electromagnetic cannon is not without shortcomings, but has more obvious shortcomings, the most significant is that it cannot be flexibly equipped with ammunition. According to the design indicators of the US military, false, tamed. There are only two levels of ammunition, one is a full load of the fierce pound and the other is a half-loaded load of the curved pound. Both have different types of ammunition, namely armor-piercing shells, semi-armor-piercing shells, high-explosive shells, cluster submunitions and multi-purpose non-anti-personnel bullets, and the biggest difference between the two is that the quality is different, and the other performance indicators are very similar. For this reason, a special adapter is also required to fire properly, and the main reason for using a half-loaded is not to increase the range, but that a full load is too expensive and too powerful against most targets other than a specific target. Of course, there is another reason that the U.S. Navy is reluctant to admit, and that is the influence of design and materials. When the electromagnetic gun shoots shells at maximum power, the working life of the adder is far lower than the tactical indicators of the navy, so the firing power can only be reduced by using semi-loaded ammunition to improve the working life of the adder. Another serious consequence of this is that the internal trajectory of the electromagnetic gun is not optimized, so it cannot be used by installing caliber adapters. The shells of the navy-type electric contact guns must be tamed according to the new standard production period, which increases the difficulty of logistics support and further reduces the general line of ammunition, making the ring too suitable for carrying out ground attack missions.

All in all, as the number one and even the only main battle equipment of the capital ship, it is tamed. Plus, performance defects will inevitably have an impact on the combat effectiveness of the "Long Beach" class.

In a certain sense, the US Navy did not hesitate to reduce the maximum navigation degree of the "Long Beach" class to a knot, but also equipped it with hundreds of missile launch tubes, which also tamed. There is a direct relationship between the performance defects and the defects. The problem is that these offensive means, which were originally used to make up for the shortcomings in the performance of the main battle weapons, have instead become the main means of attack in the eyes of US commanders, that is, the "Long Beach" class is not a capital ship that fights with large-caliber electromagnetic guns, but an "arsenal ship" that uses anti-ship missiles, especially heavy anti-ship missiles with a range of 1,000 meters. Let's not talk about "Long Beach." How much of a threat the heavy anti-ship missiles on the class can pose to the "Qin" class, let's first look at the tactical thinking of the US military.

As mentioned earlier, the maximum firing range of Chitun is about 1,000 kilometers, but in the case of a single operation, the maximum effective firing range is only 4,000 meters, and it is possible to reach the maximum range of 1,000 kilometers only with intelligence support. This shows that it is no longer the range of fire that restricts the combat distance of weapons that dominates the sea, but the means of observation and guidance, that is, the ability to collect tactical intelligence. There is no doubt that this question is in the "Qin." The body of the class is also very clear, that is, in the case of relying only on the detection means of the ship, the normal combat distance must be within a thousand kilometers. Broadening our horizons a little further, even in aircraft carrier battle groups, reconnaissance means are still the main factor restricting the attack capability of carrier-based air forces. For example, in the naval battle of the Maldives, the US fleet, which had lost the support of shore-based air forces, had to come up with valuable heavy fighters to carry out reconnaissance missions, which had a serious impact on the fleet's air defense operations and offensive operations. In the next Battle of the Marianas. Both the Republican Navy and the U.S. Navy fleets operated in the absence of shore-based support, and both suffered heavy losses as a result. These examples are enough to show that until more effective means of intelligence gathering are obtained, increasing the attack range of sea supremacy weapons, or the attack range of sea supremacy weapons, has little impact on naval warfare.

From this, it is not surprising that the Navy of the Republic does not equip the "Qin" class with other sea-supremacy weapons.

To put it bluntly, when it is very difficult to detect targets that are thousands of kilometers away, it is necessary to find targets that are far away, such as those that are thousands of kilometers away. It's almost impossible. And so it goes. It would be pointless to equip warships with heavy cruise missiles with a range of thousands of kilometres.

Some people may say that in the era when joint operations are all the rage, the performance of one weapon is not enough to determine the performance of the entire weapon system, and when formulating performance indicators, we should not be limited to the scope of our own tactical use, but should comprehensively consider the performance indicators from the height of the weapon system.

There is nothing wrong with this statement, but the specific implementation method is open to debate.

Because in the face of modern air defense systems, especially the fleet air defense systems that combine software and hardware, the combat efficiency of aviation is already very low, and only the "naval type" can really be expected to make a comeback of the "aircraft carrier." It is impossible for this new fighter to be put into battle for a while and a half, and it is impossible to immediately station it on an aircraft carrier, so under the current situation, the capital ship with the new electromagnetic cannon as the main combat weapon has become the most effective combat platform for sea domination. In a fleet with capital ships as the core, what is most needed is long-range reconnaissance means. Although in the maritime battlefield, the most ideal reconnaissance platform that can accompany the fleet's high activity is the heavy fighter planes deployed on aircraft carriers, it is obviously too extravagant to equip the main fleet with aircraft carriers for the sole purpose of reconnaissance. More importantly, the main task of a heavy fighter is air defense, not reconnaissance. In the case of mere reconnaissance purposes, there are many other means of replacing heavy fighters. For example, the use of electromagnetic guns to shoot two "artillery launched unmanned reconnaissance aircraft" with autonomous navigation capabilities. That is, what is often referred to as "reconnaissance shells". Theoretically speaking, the range of the reconnaissance shell must be a little longer than that of other ammunition, and the range can be increased by adding endurance motivation and so on, so that the reconnaissance shell can fly autonomously for a period of time when it reaches the target area. The problem is that this does not mean that in naval battles with capital ships as the main force, the longer the engagement, the better.

What determines the engagement distance of the capital ship is not only how far it can be seen, but also whether it can be accurately hit.

Although in the era of mass application of electronic devices. There are already no unguided munitions in the absolute sense of the word. That is, all ammunition uses a guidance and control system, and even some small-caliber ammunition has a muzzle correction system. However, in order to deal with the forced electromagnetic interference system, the sea control ammunition of the capital ship adopts the terminal unguided attack method. That is, at the end of the trajectory, the flight path of the shell is no longer controlled. In this way, when attacking sea targets, the accuracy of the large-caliber electromagnetic guns on the capital ship will definitely not be too high. The enemy can only be hit by increasing the density of shelling. Because the range of the shell increases with the range, and is generally proportional to the range, no matter what the electric bombardment, it is necessary to ensure that a round of shelling at least hits the target, or that the mission accuracy rate reaches a certain standard. There's a maximum range. In fact, this is basically the maximum effective range of the electromagnetic gun.

As mentioned earlier, the maximum firing range of the new electric contact cannon of the "Qin" class capital ship is very likely to be about 1,000 kilometers, but in actual combat, the maximum engagement distance is about 1,000 kilometers, and it is rarely exceeded, such as 1,000 kilometers. A very crucial reason is that at the kilometer of the mouth, the range of shells is already very large, and it makes no sense to continue to increase the range in order to ensure that at least one shell hits the target in a single round of shelling. What's more, the reserve ammunition of the main gun of the "Qin" class is very limited, and if it is fully fired, it will last for a few minutes at most, and the duration of any naval battle will not be so short, so when it is used in combat, it is definitely necessary to try to close the distance and improve the hit rate. Reduce ammunition consumption.

Because it is equipped with several hundred missiles, and an area air defense system is also added, so ... It is unlikely that the ammunition reserve of the "Tiantan" class Xin cannon will be the enemy of the "Qin" class, even if it is too much in a hurry. In this way, unless the US commander has sufficient confidence in the long-range anti-ship missiles on the warship, he will not fire at the "Qin" class from a distance of 1,000 kilometers. Instead, we should do everything we can to shorten the distance of engagement to, for example, within 10 meters, or even 4,000 meters.

At this time, if we look back at the long-range anti-ship missiles equipped on the "Long Beach" class, even if these missiles can allow warships to attack from a distance of thousands of kilometers, in the case of a limited number of them, and they have to break through the enemy's integrated fleet air defense system, their actual combat value really needs to be discussed.

Of course, before using these "heavy weapons", the US military first had to find the capital ships of the First Main Fleet.

In the night, the First Fleet did not change course. Still following the predetermined course, heading towards the sea west of Guam. If the First Main Fleet of the Republic Navy does not leave the previous sea area, then after two hours, the First Pilot Fleet will enter the main artillery strike range of the First Main Fleet, and in another two hours, that is, at about midnight on the day of the moon, the First Pilot Fleet will also be able to bombard the First Main Fleet with its main guns.

It's just that the US commanders are not so optimistic. By this time, the significance of the occupation of Saipan by the Navy of the Republic had already been manifested. Because the Republican Marine Corps has deployed an artillery brigade on Saipan, which is equivalent to the artillery brigade of the Army's combat units, it is bombarding military bases on Guam with high-kilogram shells around the clock. In particular, Andersen Air Force Base with Apra Naval Base. So a few months ago, the U.S. military withdrew all shore-based air forces from Guam, sending only a few seaplanes to Apra Naval Base occasionally, or when it was necessary to carry out long-range reconnaissance missions. It was from here that the seaplanes went north to search for the 1st Main Fleet before making a brief stop at Apra Harbor. Also receiving priority was the naval air station on Tinian Island, as well as several makeshift seaplane bases.

In other words, the closest air base to the First Fleet is a sea base more than four kilometers away.

The operation of the First Fleet is described as a lone army. Not too much at all.

Of course, there is no need for US commanders to be nervous.

Threatened by the regional air defense systems deployed on Tinian, Rotau and Guam, the reconnaissance aircraft of the Navy of the Republic had no chance to approach Guam at all, and rarely even went to the waters south of Guam. Similarly, U.S. Marines deployed on Guam are bombarding Saipan with electromagnetic cannons, making it impossible for Republican Marines to repair the island's airfield and therefore deploy fighter jets on Saipan.

All in all, the problems of the US military. The Navy of the Republic also exists.

It can be said that after several months of fierce fighting, the aviation forces of both sides have long been exhausted, and it is difficult for both sides to organize a large-scale air offensive campaign, except for sending a few reconnaissance planes to assist the fleet. It will be difficult to pose a threat to the opposing fleet. Not to mention the fact that after the decisive battle of the fleet, the victorious side will definitely attack in a big way, and the losing side will defend with all its might. When the time comes, the significance of aviation will be even more significant.

Speaking from facts, the US military still has a slight advantage, because Guam has a submarine depot that cannot be defeated with electric artillery!

Although there is no way to prove that at the beginning of the warp. How many submarines the United States has deployed on Guam. However, according to some information on the submarine cave, especially the maximum support capacity, and the efficiency of the submarine's sorties, and the fact that at the beginning of the year, the first batch of "portable attack submarines" built by the US Navy according to wartime standards had been launched into service, and the approximately powerful ships built at the shipyards on the west coast of the United States must have arrived at the front line, and there was enough intelligence to prove that these submarines did not go to Pearl Harbor. Nor did they go to Australian ports, but it can be roughly concluded that the number of attack submarines operating at Guam's submarine depot at that time must have been more than a force number, and the number of submarines deployed in Guam at that time should have been between four and four at that time, including the numerous attack submarines built before the war. And it's mostly west of the Mariana Islands.

Comparatively speaking, the submarine forces of the Navy of the Republic in the western Pacific are not so concentrated.

According to the information published by the Navy of the Republic after the war. At the beginning of the year, the total strength of the submarine force was the core ships, some of which were attack submarines built before the war, and some of which were attack submarines built after the explosion of the war, of which the four ships that were sent to Argentina to carry out reconnaissance and diplomatic relations breaking missions were to attack Nigeria against Romeroon. In addition to the mouth ships assigned to the fleets, there are knife submarines that carry out missions in the Pacific. Only half of them are sent to the southwest Pacific, and at least some of the remaining islands are active in the North Pacific and Northeast Pacific. In other words, at that time, only one attack submarine was actually operating in the western Pacific, and at least several of them were protecting three sea bases. The main task of other attack submarines is also to hunt down the U.S. Navy's attack submarines and transport fleets. Instead of squatting in the waters of the Mariana Islands. Waiting for the first fleet to come to the door.

Although there was no reason why the authorities of the Republic should not deploy a few submarines south of the Mariana Islands under the circumstances, the threat of the US anti-submarine system certainly prevented these submarines from getting too close to Guam. Of course, the noise generated by the First Fleet at high altitude can be transmitted hundreds of kilometers away, but if the distance is too long, the attack submarines of the Republic Navy are not only unable to ambush them. It is also impossible to determine the specifics of the first fleet.

More importantly, judging from some information released by the authorities of the Republic after the war, except in the first half of the first half of the year, when there was a serious shortage of troops, especially when the anti-submarine forces were seriously insufficient, the Navy let some attack submarines perform secondary tasks such as reconnaissance and escort. Since the second half of the year, with the rapid increase in the output of reconnaissance aircraft and anti-submarine frigates, the navy has never let attack submarines play soy sauce, but has allowed them to return to their true colors. Do what you do best, and carry out free hunt missions on the enemy's lifepath.

It can be said that the commander of the US military basically does not have to worry about coming from under the surface of the sea

From the standpoint of the First Fleet, there is only one thing that needs to be done before a decisive battle with the First Main Fleet, and that is to find the First Main Fleet.

As mentioned earlier, even without support, the main fleet still has relatively reliable means of reconnaissance and search.

This is the "reconnaissance shell" fired from the main gun.

Technically, in the era when the mass of military reconnaissance satellites can be reduced to less than four kilograms. "Reconnaissance shells. It is not "high-tech equipment at all" Structurally speaking, "reconnaissance shells" are unmanned reconnaissance aircraft fired with large-caliber electromagnetic guns and equipped with sensors. Because the muzzle degree of the spiral electromagnetic cannon is more than 10 meters per second, and theoretically it can even reach 2o kilometers per second, so it is only necessary to equip the "reconnaissance shell" with a rocket booster motor to make it reach the first cosmic degree, so as to obtain an infinite range. Of course, these are all theories, not to mention whether there is technical difficulty for the time being, just the infinite range does not have much practical significance.

Of course, the "reconnaissance shell" is not a panacea, but has a significant performance flaw.

As can be seen from the previous introduction, the large-caliber electric contact cannon can actually be used as the first stage of power for the spacecraft, that is, the spacecraft is added to 4 kilometers per second with a large-caliber electromagnetic cannon, and then the booster rocket on the spacecraft continues to add it to reach the first cosmic degree. With the increase in the performance of the electromagnetic gun, it is even possible to directly add the spacecraft to a per second? The first cosmic degree of the mouth kilometer. The problem is that neither the Republic nor the United States fired shells into the atmosphere with electromagnetic cannons throughout the war. The reason is also very simple, the length of the electromagnetic cannon is only a few meters, at most tens of meters, in such a short distance, the shell is added to 4 kilometers per second, which is equivalent to an average increase of tens of thousands, and the instantaneous increase is more than a million. Such a huge increase has very high requirements for the structure of the shell and the equipment inside the shell. Not to mention the sophisticated electronic equipment on the satellite, even the sensors in the "reconnaissance shells" have to be customized. More importantly, during the firing process, the shell is under a strong magnetic field and needs to be shielded, which puts forward new requirements for the structure of the shell.

Affected by this, "reconnaissance shells. In fact, it is only a pre-war reconnaissance means, not a tactical reconnaissance means.

Although, theoretically, it is also possible to use "reconnaissance shells." to carry out tactical reconnaissance missions, that is, to search for attack targets in a relatively large area. But "reconnaissance shells" produced according to specific standards. The price is hundreds of times higher than that of ordinary shells, and the space in the ammunition depot of the capital ship is already limited. So no fleet commander will use "reconnaissance shells" to carry out the tasks of reconnaissance aircraft.

Because "reconnaissance shells." The technical content is not too high. Therefore, the US military manufactures "reconnaissance shells" according to the caliber standard of semi-loaded ammunition. Of course. In the fleet, "reconnaissance shells" do not belong to ammunition, but to expendable electronic equipment, along with jamming shells, decoy shells, etc.

In combat use, reconnaissance planes and other reconnaissance forces first search for enemy fleets over a large area. Only after mastering the basic whereabouts of the enemy fleet. And after determining the approximate location of the enemy fleet. The fleet commander will use reconnaissance shells to accurately locate the enemy fleet before the attack, and at this time, the reconnaissance planes and other supporting forces will retreat, or temporarily withdraw from the combat area, so as not to be accidentally injured by friendly forces; if the combat distance is too far, the reconnaissance planes and other support forces will be responsible for signal relay near the battlefield, and if the reconnaissance planes cannot stay near the battlefield, such as being attacked by enemy fighters, the fleet needs to spread some high-altitude signal relays before the target, and these tactics are clearly stipulated in the US military's code of operations. Then the shelling was carried out using the information provided by the reconnaissance shells.

It can be seen from this that there are two choices before the US commanders.

The first is to use the information provided by reconnaissance planes during the day. The computer analyzes the navigation data of the First Main Fleet, and then projects "reconnaissance shells" on the route of the First Main Fleet, so as to find the First Main Fleet before dawn and attack before the First Main Fleet. There is only one problem with this: "It is very likely that the First Main Fleet will change direction at night, thus frustrating the search, or it will need to consume more "reconnaissance shells" to be able to reach the target. Putting aside for the time being whether the firing of "reconnaissance shells" will expose the whereabouts of the first fleet, the electromagnetic cannon will definitely produce a strong electromagnetic field when it is working, even if it is shielded, it cannot be completely shielded, for example, at the moment of firing the shell, a strong magnetic field will be generated at the muzzle, and this degree of field disturbance is simply a lighthouse in the dark for the passive detection system. If too much "reconnaissance shells" are consumed. Failing to find the target again will definitely have an impact on the daytime battle.

The second is to approach the battlefield at night and wait until after dawn for reconnaissance planes to look for the first main fleet. Then attacked. It's safer to do that, but there's an equally serious problem. That is, the longer the First Fleet is delayed near the battlefield, the greater the probability of exposure, and it is possible to expose its whereabouts first and be suddenly attacked by the First Main Fleet. If we take into account the superiority of the 1st main fleet in the range of the main guns. The First Fleet hovered outside the battlefield, waiting for tactical intelligence, undoubtedly sitting still.

Yan Ran, these other options are not ideal, and they all have merits.

It can be said that whoever rises to the position of commander of the first fleet will be very difficult. Although front-line commanders must have the quality to make decisions on the spot, and when they are in a dilemma, they have to choose the lesser of two evils rather than hesitate, but when they are unable to weigh the stakes quickly, or are unable to weigh the stakes quickly. It is not surprising that the commander has become indecisive. When the commander hesitated. The First Pilot Fleet still sailed westward, heading for the sea where the First Main Fleet was located.

Although many people later believed that the indecision of the US commander was the first and main reason for the burial of the First Fleet, judging from the situation at that time, it was necessary to defeat the First Main Fleet and seize sea supremacy.
