Why didn't that Newland submarine attack the 41st Special Mixed Fleet?

Also, has the identity of the 41st Special Mixed Fleet been determined, or has it only detected the noise caused by a suspected large aircraft carrier?

Bai Huawei thought it was easy to understand the first question.

Relying on passive sonar, especially the advanced towing line array sonar, and making full use of the submarine channel aggregation area, submarines can find groups of moving warships hundreds of kilometers or even hundreds of kilometers away. Although it is difficult to determine the exact location of noise only with passive sonar. If the signal obtained through the submarine channel aggregation area, it is impossible to accurately judge the actual distance from the noise. However, for submarines performing reconnaissance and search missions, the main task is to discover aircraft carriers, not to accurately locate aircraft carriers.

As for ambushing aircraft carriers, it is even hard to come by.

Several submarine-launched anti-ship missiles were unable to break through the air defense network of the aircraft carrier battle group at all. The torpedo with better penetration capabilities also had the problem of insufficient range.

In fact, the anti-submarine network of any fleet has clear targeting.

For example, the anti-submarine network of the Imperial Fleet is divided into three layers: outer, middle and inner layers. The outer anti-submarine network can be expanded to a distance of 500 outside the aircraft carrier. This distance targets submarine-launched long-range anti-ship missiles, especially the BGM-109B anti-ship "Tomahawk" missile with a range of 460 kilometers. The mid-submarine network is between 50 kilometers and 150 kilometers, and the range covers basically various types of anti-ship missiles. Within 50 kilometers, it belongs to the inner anti-submarine network, and the key areas are generally less than 30 kilometers, and the main target is heavy torpedoes.

All anti-submarine platforms and ammunition of the Imperial Navy are based on this benchmark.

The main force of the peripheral anti-submarine is the carrier-based anti-submarine patrol aircraft, and only the carrier-based anti-submarine patrol aircraft can fly 500 kilometers away, and spend a few hours searching for submarines hidden under the sea. The middle-level anti-submarine mainly relies on anti-submarine helicopters, while the inner anti-submarine uses anti-submarine missiles and anti-submarine torpedoes.

Even the large attack submarine of the Newland Navy may not be able to successfully break through the Imperial Fleet's anti-submarine network.

If the Newland submarine is performing a search mission, it will immediately report to the superiors after detecting the 41st special mixed fleet.

To avoid being attacked, the captain of the submarine will set the time for the sending of the report to a few hours later.

As a result, by the time the 41st Special Mix fleet approached, the submarine had already slipped away.

Conversely, if the Newland submarine does not slip away, it may not be possible to get a sneak attack, because it is very likely to be discovered by an anti-submarine patrol aircraft before launching the sneak attack.

The key is that the sea area where the submarine was located was not directly in front of the 41st Special Mixed Fleet route.

During rapid transit, the aircraft carrier battle group usually only conducts key searches on the waters ahead of the route, covering at most tens of kilometers of seas on both sides of the route. If there are no special circumstances, the commander of the aircraft carrier battle group will not expand the scope of anti-submarine search for no reason.

This is even more so for the 41st Special Mixed Fleet.

As mentioned earlier, the 41st Special Mixed Fleet has only 12 anti-submarine patrol aircraft in total, and in theory, it can only be dispatched 3 missions at the same time. To expand the search range and to deploy more anti-submarine patrol aircraft, it is impossible to ensure that anti-submarine searches in the main direction can continue. After increasing the dispatch intensity, usually, adjustments to the anti-submarine arrangements need to be made in 12 hours or up to 24 hours, that is, anti-submarine patrol aircraft that can be dispatched at that time will definitely not guarantee the demand in the main threat direction.

If the threat is particularly serious, adjustments must be made to the fleet's combat deployment.

In any case, the Newland submarine must have been performing a reconnaissance and search mission, and the 41st Special Mixed Fleet was discovered a few hours ago.

The key is, why didn’t the telegram be sent immediately after discovering the 41st Special Mixed Fleet?

Obviously, this is a question worth pondering.

According to Bai Huawei's judgment, the Newland submarine did discover the 41st Special Mixed Fleet, but it did not confirm the identity of the 41st Special Mixed Fleet as soon as possible.

Otherwise, the report will be sent as soon as possible!

A few hours ago, the 41st Special Mixed Fleet was more than 100 kilometers south, and there was a destroyer not more than 50 kilometers away from the submarine.

This distance is quite fatal.

As long as the whereabouts are exposed and the destroyer is not sunk immediately, even if the anti-submarine helicopter on the destroyer is hung on a torpedo and even an alarm is issued, the Newland submarine will not escape, and will definitely be sunk by the anti-submarine helicopter and anti-submarine patrol aircraft that arrived in dozens of minutes. If it has been concluded that the 41st Special Mixed Fleet is coming from the south, there are 3 large aircraft carriers inside, that's nothing. If the Newland submarine does not confirm the identity of the 41st Special Mixed Fleet and cannot confirm that three large aircraft carriers have been discovered, then you can't take the risk.

The impact of a false intelligence is much more serious than the lack of intelligence!

In fact, it is indeed difficult to make an accurate judgment based on the noise intercepted by passive sonar after more than 100 kilometers.

The key is that the three "Chen Bingxun" class of the 41st Special Mixed Fleet have been in service for decades, and many of the technologies they use are no longer advanced. For example, the 5-leaf adjustable pitch propeller specially developed for it was considered unique to the world more than 20 years ago, and now it is equipped with almost all super cargo ships. Besides, the aircraft carrier will be docked every few years for a comprehensive maintenance, which will definitely clean the bottom of the ship and remove aquatic organisms such as barnacles attached to the hull. The result is that the noise characteristics of the aircraft carrier are no longer special and will change frequently.

Overall, when an aircraft carrier sails at a cruise speed, the noise emitted is not very obvious different from that of large cargo ships with equivalent displacement.

Only when an aircraft carrier sails at high speed or is close enough can it be distinguished.

Because Bai Huawei has not made the final decision yet, the 41st Special Mixed Fleet has been sailing at cruise speed, and it is an anti-submarine formation.

In order to avoid multiple warships being attacked by one submarine, the warships are relatively far apart.

Based on these factors, we can fully believe that the Newland submarine only discovered the 41st Special Mixed Fleet and did not determine the identity of the 41st Special Mixed Fleet.

The key is that the identities of the three aircraft carriers have not been confirmed!

This inference made Bai Huawei feel embarrassed.

If you are sure that your whereabouts have been exposed, then what you should consider now is not to go to the Northeast Ocean or to Yoton Island, but to leave the dangerous seas as quickly as possible, and report the matter to your superiors, and then spend a few days to re-determine the combat plan.

It is not about re-designing a combat plan, but Bai Huawei actually has a ready-made plan.

It is most important to spend a few days to restore the 41st Fleet to the concealed state, so that the enemy cannot speculate on the whereabouts of the 41st Fleet through the reports provided by the submarine. Only after the concealed state is restored, will the decisive battle with the Newland Fleet be considered.

The reason is also very simple. The Imperial Navy is on the defensive side and has the advantage of time.

Change the angle and see it more clearly.

After receiving the telegram from the submarine, the commander of the Newland Fleet first thought was that the 41st TF fleet was heading north and would enter the Northeast Ocean through the Howai Islands in two days, or reach the waters near the Howai Islands. Under the threat of the 41st TF fleet, the commander of the Newland Fleet would inevitably make adjustments to the combat operations, and the easiest thing was to cancel the original combat plan.

In this way, the Newland Navy would give up and at least postpone the combat operations to attack the Aliu Islands.

If the Newland Fleet is sailing in the east and the southern waters of Yoton Island, it will also make adjustments to the combat operations after receiving the submarine report. To put it simply, if it is confirmed in two days that the 41st Special Mixed Fleet has arrived in the North and the Hovay Islands, the Newland Navy will definitely give up the sneak attack and may even end the first phase of the strategic offensive.

Don't forget that the only purpose of the Newland fleet heading to the southern waters of Yoton Island was to attack the 41st Special Mixed Fleet.

The problem now is that none of these assumptions hold true.

Without knowing whereabouts of the 41st Special Mixed Fleet, the Newland Navy had no reason to adjust its combat plan and would not make rash changes.

In this case, why did the submarine send a telegram?

Why not send a telegram after confirming the 41st Special Mixed Fleet?

The key is that it may be a submarine dedicated to performing reconnaissance missions.

Obviously, sending a telegram without confirming the 41st Fleet is a low-level mistake that a qualified submarine captain should not make.

What if this is not a low-level error?

Thinking of this, Bai Huawei was shocked!

If that submarine deliberately ruled and used sonar buoys to expose its whereabouts, it would be not to report the situation, and it would definitely have other intentions!

What's the picture!?

The sea area where the submarines sent the report is at the right rear of the 41st Special Mix Fleet, that is, the southeast direction, and Yoton Island is also in this direction.

Could it be that the Newland submarine is worried that the 41st TF fleet would turn to sail towards Yoton Island!?

Bai Huawei didn't think much about it and immediately asked the staff to dig out the navigation log.

As he guessed, after turning north, the 41st Special Mixed Fleet would make a tactical turn to defend against submarine every about 6 hours.

The last turn was about 4 hours ago.

Perhaps, it was at that time that the Newland submarine discovered the 41st special mixed fleet.

By sending a telegram, it is actually to force the 41st special fleet to continue northward.

To put it bluntly, after confirming that the whereabouts had been exposed, Bai Huawei's first thought was to continue to go north, but not to look northeastern, but to the west of the Hovay Islands and obtain the cover of several islands deployed there, such as the shore-based aviation force on the transit island.

This move will inevitably make the 41st Special Mixed Fleet more susceptible to ambushing.

First of all, because of worrying that there are enemy submarines nearby, the 41st Special Mixed Fleet will inevitably slow down and strengthen anti-submarine search efforts. The speed of going north will slow down, and it is more likely to be caught up by the Newland Fleet that came from the east, and will eventually be attacked for neglecting air defense.

In addition, when returning to the waters near the Hovayi Islands, Bai Huawei will definitely pay more attention to the battle in the Northeast.

At this time, the Newland Navy is likely to adopt the tactic of striking the east and attacking the west, that is, to attack an island in the Aliu Islands according to the method Bai Huawei had previously speculated, such as Ebony Island, so that the Imperial Navy could take this opportunity to win back a city, and to send the 41st special fleet to fight to the decisive battle.

Obviously, the Newland Fleet was not in the Northeast, at least not in the Northeast now.

What will be staged at that time is the good show where the mantis stalks the cicada and the oriole is behind.

When making this speculation, Bai Huawei thought of something.

Regardless of whether the Newland submarine has confirmed the identity of the 41st Special Mixed Fleet, there is no reason for sending a telegram at this time, that is, after the 41st Special Mixed Fleet approaches, it will take at least 2 days before the 41st Special Mixed Fleet to enter the Northeast Ocean. The Newland submarine only needs to wait for a few more hours to send a safer and more concealed way.

Can't wait for hours!?

There is no doubt that this is obviously unreasonable.

In this world, the one who is most impatient is probably the captain of the submarine.

For a submarine captain with a major mission, it was not difficult to wait for a few hours after discovering the enemy's fleet, especially after confirming that there were aircraft carriers in the fleet. In the past, in order to obtain an ideal fire opportunity, the submarine captain would spend several days tracking the enemy fleet.

Based on these, Bai Huawei has enough reason to believe that the purpose of the Newland submarine's move is actually to allow the 41st Special Mixed Fleet to continue north, but it has to slow down its navigation speed and spend more energy on searching for submarines lurking nearby in the next few days.

This means that the Newland fleet will arrive within a few days.

Then there is only one possibility.

The information provided by the Military Intelligence Bureau is true!

The Newland Fleet is still looking east and west. On the north and east, it is actually several "civil aircraft carriers" and at most several amphibious assault ships.

The key is that the Newland fleet will definitely not be able to arrive in time, and there is a time difference of several days.

Otherwise, the Newland submarine would not have taken the risk of sending a telegram.

This means that as long as you make full use of these days, you may be able to turn the situation around in one fell swoop!

After this idea came up, Bai Huawei did not take action immediately, but asked the communications officer to use satellite radio to send a telegram to the Navy Command.

This move is to prove this speculation.

The solution is also very simple, let the Navy Command take appropriate measures, such as adjusting the deployment to lure the Newland Navy to launch an early action, that is, to feint the attack on the Aliu Islands.

If the Newland Fleet is really east of Yoton Island, then when the 41st Special Mixed Fleet has been discovered, especially the Imperial Navy begins to increase its troops on Yoton Island, the Newland Navy will definitely launch a feint attack in advance to distract the Imperial Navy.

Only in this way can we get the opportunity to sneak attack the 41st Special Mixed Fleet.

Obviously, after so many things, the Newland Navy is definitely not fighting head-on with the 41st Special Fleet.

As long as the Newland Navy launches combat operations against the Aliu Islands in the near future, even if it attacks an island, it can prove that the Newland Viagra, which has five aircraft carriers, is on the side of Yoton Island, and has entered a state of combat, ready to attack the 41st Special Mixed Fleet operating in this direction at any time.

Unfortunately, Bai Huawei also knew that he could not wait until he confirmed this speculation before ordering to turn.

It will be too late to make adjustments at that time!
Chapter completed!
