Chapter 1004 Satellite Staring Reconnaissance
“Kitty Hawk?”
Upon hearing this conclusion, the eyes of several naval officers in front of the big screen lit up almost at the same time.
The expressions on his face are even more wonderful.
In fact, just now, everyone had some speculation about the nature of this goal.
Just because they were worried that the joy would be in vain, no one dared to jump to conclusions.
But now, with the news that happened to be released by the United States as circumstantial evidence, it is basically stable.
This sea area was not a busy international waterway to begin with, but suddenly something with a size of about 300 meters * 40 meters appeared, and the heading and time period were consistent.
It's almost impossible to think otherwise.
"Finally..."
The one with the highest rank among the people let out a long sigh, then walked to the big screen, put his hands behind his back, and looked up at the small, slightly distorted light-colored shadow.
I don't know if it's due to psychological factors, but after hearing the news just now, looking at it with the naked eye, it seems that the deck of an aircraft carrier has some angular appearance...
"Finally I caught you..."
he muttered under his breath.
As the flagship of the Seventh Fleet for a long time, the Kitty Hawk has been active in various hotspots around China for most of its service life.
Thanks to the fact that conventionally powered aircraft carriers do not need to undergo ultrlong maintenance and replacement of nuclear fuel, their effective time in flight is much longer than that of their later nuclear-powered descendants.
Especially after entering the 1990s, he has been acting as a vanguard.
Although the Kitty Hawk did not appear in the most well-known incident in 1996, two years earlier, in 1994, it had a confrontation with the then-weak Chinese Navy and Air Force.
That is to say, after entering the 21st century, due to the long service time and the fact that it went to the North Arabian Sea to participate in a round of Operation Enduring Freedom in 2001, it has slightly faded out of sight in the past two years.
But no matter what, the Kitty Hawk is definitely an old acquaintance to the Chinese Navy.
And it's the kind that's not easy to deal with—
In terms of dispatch rate alone, aircraft carriers certainly cannot compete with land airports.
After multiple models of second-and-half-generation and third-generation aircraft have entered service, the quality of the Chinese Air Force's small-scale top combat capabilities is not as good as those of the F14 or F18.
But here's the thing.
As a mobile airport on the sea, aircraft carriers have unparalleled initiative.
As a defender lacking countermeasures, China often needs to infer the whereabouts of the opponent's fleet through public information as just now.
And unless it docks at a certain port, this speculation is inaccurate.
Moreover, if others really want to do something, they will often hide it or even deliberately provide false fleet navigation information.
In this case, only when the target is very close to the coastline, the opposite position can be tracked through sea detection radar or reconnaissance aircraft.
However, the over-the-horizon radar is subject to principles, and its accuracy is generally very poor.
It is difficult for reconnaissance aircraft to break through the air defense circle, intercept and rush to the opposite side.
This is why, even when it was about to be replaced at a high speed, the Navy still squeezed out part of the funds to support the technical verification project of Ocean One.
However, today's experience has been full of ups and downs.
First of all, when Ocean One was turned on for the first time, it actually captured a valid target.
As a result, before I could feel happy, a basin of cold water was poured down my head—
Few imagined that ocean remote sensing imaging could be so abstract under certain circumstances.
The scenario in which a large number of remote sensing images are sent back by satellites and then analyzed and judged by the staff unit to finally form a strike chain is obviously not that easy to solve. However, on the other hand, the final results seem to prove that the spaceborne program's ability to identify target features is stronger than expected.
The staff unit is under great pressure, but the pressure on the staff unit is not that great...
"The effect of this satellite is almost as good as all the reconnaissance methods we used in the past..."
Chen Da from the General Armament Department came directly behind Chang Haonan:
"Comrade Weiyong, and Xiao Chang, in your opinion, if we want to achieve uninterrupted continuous surveillance in the Pacific Ocean...at least the waters surrounding our country in the western Pacific, how many satellites like Haiyang-1 need to be launched?"
Chen Dazhi served as deputy director of the Commission of Science, Technology and Industry for National Defense for a period of time before taking up the post of deputy director of the General Armament Department. Although he was transferred before Chang Haonan became famous, he was still among the first group of people to have contact with Chang Haonan.
The title has been retained habitually.
This somewhat sudden question made it difficult for Zhang Weiyong and Chang Haonan to answer for a while.
Obviously the equipment department is encouraged by what happened today.
So I got some new ideas.
According to the original plan, after the successful technical verification of Haiyang-1, the real ocean surveillance satellite will be developed and launched in 5-6 years.
But looking at what it means now, users don't seem to want to wait anymore...
The two looked at each other, and it was Zhang Weiyong, a satellite expert, who gave his opinion first:
"Director Chen, if we want to achieve truly effective military reconnaissance and surveillance, we may not be able to achieve it only by relying on satellites like Haiyang-1."
"The sun-synchronous orbit satellite has an approximately circular orbit. The advantage is that a satellite can scan almost the entire earth's surface in one day, and it scans the same point at the same time every day. As for Haiyang-1, it will scan at 9 a.m. every day. By passing through my country's Kashgar Measurement and Control Station.”
"But the height of the sun-synchronous orbit is not high, and due to the performance of the current satellite equipment, it cannot provide a particularly wide viewing angle, so the range of each shooting is actually very limited... Such a satellite is more suitable for global coverage Monitoring, rather than revisiting a certain point frequently..."
"In short, achieving 24-hour uninterrupted reconnaissance and surveillance around our country is as difficult as conducting 24-hour uninterrupted reconnaissance and surveillance at any point in the world..."
“What about geosynchronous orbit?”
Chen Dazhi still didn't give up. He studied missile technology when he was in school. Although he didn't completely match his skills, he wasn't blind.
"Geosynchronous orbit can indeed ensure continuous monitoring of a relatively large range, but the orbital height is too high and requires very advanced imaging equipment... There is almost no demand for this type of equipment except for military use, and the core components are monopolized by the Americans. , Even if we have good relations with Europe now, it will be difficult to get finished products.”
"In addition, even if the equipment problem is really solved, it will still require a very large satellite to carry it, and it will also require a large energy supply, and the weight will increase accordingly... The current Dongfanghong 4 is not enough in any case. In addition, to launch a behemoth of more than ten or twenty tons into geosynchronous orbit requires a heavy-duty rocket much larger than the Changsanyi..."
Obviously, although China has developed quite rapidly in recent years, facing this kind of systemic backwardness, it is still not something that can be easily recovered.
Looking at Chen Dazhi with an expression of "Master, please stop reading", Luan Wenjie, who is in charge of the development of the entire aerospace industry, shook his head helplessly and said comfortingly:
"It's not that there is no good news. Now the 10-ton Dongfanghong-5 satellite platform and several new launch vehicles with take-off weights in the 500-1,000-ton range have begun to be demonstrated. It is estimated that the project will be approved soon. The 20-ton I dare not say, but it shouldn't be a big problem to put a 15-ton object into geosynchronous orbit in the future..."
Chen Da said frankly that you are coaxing children here. It is normal for more than ten years to pass from the beginning of demonstration to the completion of research and development...
But when the words came to his lips, he looked at Chang Haonan, who was standing beside him with his head bowed silently, and finally held back.
"Actually...it's not necessarily impossible."
At this moment, Chang Haonan suddenly spoke:
"The current Haiyang-1 is a technology verification satellite, so the shooting angle of the on-board equipment is fixed and is limited to just below the satellite. If you want to adjust the shooting angle, you need to spend fuel to adjust the attitude of the satellite itself."
"But if we remove other functions on a specialized ocean reconnaissance satellite, and use the extra space and power to install a staring device... it will be similar to a human neck... er... or an owl's neck."
Chang Haonan felt that language alone might not be intuitive, so he asked a staff member next to him for a piece of paper and drew a schematic diagram with a few strokes:
"The shooting angle can be adjusted while the satellite itself is stationary. In this way, the effective reconnaissance time provided by one satellite will be greatly improved, and the number of satellites required can also be reduced to...probably single digits."
