Siheyuan: I eat melons while doing scientific research

Chapter 1176: Like a Fishbone Stuck in the Throat (Today's)

A Citigroup attack formation is flying over the North Bay.

These are four F-4s. Although they were named "F" for fighter jets, they mainly carried out tactical bombing missions in the early days of the Jiaozhi War and were considered the forerunners of the F-105 and F/A-111.

The pilots maintained radio silence, and there was no radio communication except for the radar scanning for possible threats. The mission plan had been issued long ago and was now on the pilots' laps. In theory, they didn't even need any communication to complete the bombing mission.

In the fighter jet cabin, the radar scanning alarm kept flashing, which was not a big problem for the pilots. The scanning was normal and it was even possible that it was a false alarm.

But things soon changed. Suddenly, radar tracking alarms sounded almost simultaneously in the cabins of the four F-4s.

"Beep...beep...beep..."

The piercing alarm sound coupled with the flashing red light immediately made the Citi pilot's heart rise to his throat.

This is a tracking alarm, not a scanning alarm. With such a tracking alarm, it is almost certain that they have been locked by the radar.

It is almost impossible for a radar to lock onto four aircraft at the same time at this time, as it does not have that capability.

However, there is almost only one possibility for this situation to occur - the radar is very far away, causing the angle formed by the four aircraft to be small enough, which allows a beam to form the illusion of tracking and locking the four aircraft at the same time.

"North?" The leader of the formation's eyes narrowed. This direction was undoubtedly extremely dangerous. It could even be said that the number of planes shot down by anti-aircraft missiles in the entire world at this time was not as many as that of the country in the north of the North Gulf.

In any case, this warning was dangerous enough, and the leader of the formation made a prompt decision: "Turn on the electronic jamming! Descend altitude and return home!"

Let's put aside the bombing and escape first. This kind of warning that has formed a stable tracking is enough to make people go to see God.

The F105 is already heavy and bulky with bombs, which makes it a perfect target for anti-aircraft missiles. It is hard to say how effective electronic interference can be, as this aircraft is not a dedicated electronic warfare aircraft, and that country is a top expert in anti-aircraft missiles.

Relatively speaking, descending altitude is more useful. Low-altitude penetration or escape are all controlled by the laws of physics. As long as the altitude is low enough, it is relatively better than electronic interference that depends on luck.

The four F-4s lowered their noses, turned around, and rushed back the way they came.

More than an hour later, at a Citi Air Force Base in South Jiaozhi, four pilots were being questioned. They ran back halfway, and even in order to reduce the weight of the aircraft to below the maximum landing weight, all the bombs on the aircraft were thrown into the sea in vain.

"...You're saying that shortly after you entered the North Bay area, you were tracked and locked by radar from the north?" an investigator asked after listening to their statements.

"Yes, Colonel, you can check the flight recorders of our four aircraft." The lead aircraft of the formation replied.

"Can you judge the distance?"

"No, Colonel." If the direction can be distinguished by distributed antennas, then the distance cannot be judged solely by the strength of the electromagnetic signal. The F-105's radar warning system is not that advanced.

"Then according to your judgment, is it possible that the radar signal came from here?" Another investigator stood up and pointed his finger at an island in the middle of the North Bay.

If it is here, it means that the actions of the Jiaozhi people and the Oriental people on this island not long ago have begun to take effect.

"We don't think it's likely." The fighter pilot frowned.

"why?"

"At that time, our location was here..." The leader of the formation pointed his finger at a sea area on the map.

"…If it comes from that island, it means the locking distance is over 80 kilometers. I don't think Orientals have this technical capability now. Or rather, we don't have this technical capability now." It seems that the leader not only has excellent flying skills, but also other technical abilities.

There is still a big difference between the distance of scanning discovery and stable tracking.

"What do you think it is, then? A ship?"

"Maybe, but our radar didn't detect any ship." The F-105's radar also lacks downward-looking capability, but sea clutter is easier to deal with than ground clutter, so there is still a probability of detecting large targets such as ships. It is probably to the extent that if it is detected, it is certain to exist, and if it is not detected, it may not necessarily not exist.

This made it difficult for them to determine whether there was a ship or not.

The colonel investigator thought for a moment and asked, "You said the radar scan warning had been on for a long time. Do you remember when it was on? How far away was it from the island?"

This question made the pilots scratch their heads. After all, compared with the life-threatening tracking warning, the scanning warning is almost not taken seriously. There are many things that need to be taken into account in the cockpit resource management of the aircraft, and they may not notice this life-threatening change at the first time. They fell into painful memories and finally gave different answers, ranging from 120 kilometers to 150 kilometers. Maybe they didn't notice it, or maybe the long distance caused the radar signal to attenuate due to the difference in the sensitivity of the warning system. They even vaguely remembered that there were higher data, but those data may come from other directions.

"120~150 kilometers..." This number made everyone present realize a problem. Perhaps the tracking signal really came from that island and could scan at least 150 kilometers, which was the distance that the other party's radar could scan.

"We are in trouble." The colonel investigator said to the base commander with a heavy voice when he was reporting the investigation results of the incident to the commander.

"Are you sure it's the signal from that island?" The base commander also understood the impact of this matter. That island could be attacked without firing a single shot. As long as they could see the sea 120 to 150 kilometers away, it would mean that the space for them to enter Beijiaozhi from the sea was compressed 120 to 150 kilometers to the south, or they could only pass through this sea area at low altitude until they entered the land.

It's still okay for fighter jets, but for bulky bombers, it's undoubtedly too difficult.

"Not sure, but it's easy to confirm..." said the colonel investigator.

The Citi Air Force in Nan Jiaozhi took off multiple batches of aircraft within one day and launched multiple directional probes towards Beijiao Island in Beihai Bay. The results of the probe left the Citi people speechless.

"General, it has been confirmed that as long as you enter a circle with a radius of about 150 kilometers with Beijiao Island as the center, you will detect the radar scanning signal. When the distance is compressed to 80-100 kilometers, you will be tracked and locked."

The Citi Air Force personnel who summarized the mission records conveyed the news to the Citi’s highest commander in South Jiaozhi.

All the Citigroup employees present were shocked. In this situation, it was almost 100% certain that there was a radar station here, and it was an Oriental radar station.

As for how the Orientals achieved stable tracking at a distance of 80 to 100 kilometers, it is no longer important here. Anyway, as long as our side does not provoke them, the Orientals are unlikely to launch an attack, and they do not believe that the Orientals have mastered any effective anti-aircraft weapons at this distance.

What’s even more terrible is the search distance of 150 kilometers.

This means that the Orientals control this area of ​​the sky, allowing Bei Jiaozhi to obtain attack intelligence on Citigroup aircraft at the first opportunity, which is a very big threat to Citigroup's air strike force.

Being prepared and being unprepared are two different concepts.

"Our offensive channel has been severely compressed..." the commander of the Citi Air Force in Jiaozhi muttered to himself.

"General, can we just..." a staff officer suggested. He didn't finish his words, but the meaning was obvious.

"No, leaving aside the air defenses on the island, it is only less than 100 kilometers away from the Orientals' land and is completely covered by their air force. If we want to bomb it, we must first pass this barrier. It is politically unrealistic and technically disadvantageous for us to engage in a large-scale air battle with them from South Jiaozhi."

There was another thing that was not said. Judging from the fact that the Orientals were able to beat Sindhu 21:0, it would be very difficult for us even if we fought an air battle with them, because that team was not a weak one.

Having participated in the Peninsula War ten years ago, he did not forget that although the opponent's air force was not large at the time, judging from the statistical exchange ratio, the opponent even had a slight advantage.

Only then did he feel that the actions of Beijiaozhi and the Oriental people towards Beijiao Island were really uncomfortable for him.

Before, they could attack the island directly, but now, they could only watch the island open its big eyes and see clearly all their tricks over the North Bay.

Cunning Jiaozhi people!

Now this Beijiao Island is like a thorn, sticking hard in his throat, and he doesn't even dare to pull it out.

Someone from the special forces nearby stepped forward and said, "General, I think it's time for us to take action."

"you?"

"Yes, as long as the submarine takes us to the vicinity of the island, leave the rest to us." The special forces members were very confident.

submarine?!

Yes, yes, yes, this is a good idea. Now the only thing that can get close to the island without being noticed is this.

"Gentlemen, this may not be a good idea. Don't forget, the last time one of our submarines was forced to surface by the enemy's anti-submarine forces while carrying out the mission of transporting Lu Song people." This incident was really embarrassing, so many people remember it.

"No, no, no. After investigation, we found out that they were at periscope depth and the periscope was discovered. This time, we let the submarine dive deeper and not surface before reaching the target area. If necessary, we will move forward at a low speed or even hover in the water. We should be able to avoid it."
