Chapter 1004 Satellite Staring Reconnaissance
“Kitty Hawk?”
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 guesses 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 is almost impossible to have it any other way.
“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. After hearing the news just now, looking at it with the naked eye now, it seems that the deck of an aircraft carrier has an angular appearance...
"I finally caught you..."
He murmured to himself in a low voice.
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 ultra-long 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 always been 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 battle with the then-fashionable Chinese Navy and Air Force. Confrontation.
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 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-a-half-generation and third-generation aircraft have been put into service, the quality of the Chinese Air Force's small-scale top combat capabilities is not inferior to 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.
Unless it is docked 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 a fake 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 the Navy, even when it was about to undergo a high-speed replacement, 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, it was the first time that Ocean 1 was turned on and it actually captured a valid target.
Before I could feel happy, a basin of cold water was poured down on me——
Few imagined that ocean remote sensing imaging could be so abstract under certain circumstances.
Imagining a scenario where a large number of remote sensing images are sent back by satellites, and then analyzed and judged by the staff unit, and finally a strike chain is formed. Obviously, it is not that easy to get around. On the other hand, however, the final results seemed to prove that the spaceborne program's ability to identify target features was 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 our past All reconnaissance methods..."
Chen Da from the General Armament Department came directly behind Chang Haonan:
"Comrade Weiyong, and Xiao Chang, in your opinion, if you want to achieve uninterrupted sea areas around my country in the Pacific...at least in the western Pacific, How many satellites like Haiyang-1 need to be launched for continuous monitoring? "
Chen Dazhi served as deputy director of the Commission of Science, Technology and Industry for National Defense for a period of time before taking office as deputy director of the General Armament Department, although he was the deputy director of the Commission before Chang Haonan became famous. They have been transferred, but they still belong to the first group of people who had 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 have 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, the user seems to be a little reluctant to wait...
The two looked at each other, and Zhang Weiyong, as a satellite expert, was the first to give his opinion:
"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."
"Sun-synchronous orbit satellites have an approximately circular orbit, which has the advantage It is a satellite that can scan almost the entire earth's surface in one day, and it scans the same point at the same time every day. Specifically, it passes through my country's Kashgar Measurement and Control Station at 9 a.m. every day." >
“However, the height of the sun-synchronous orbit is not high, and due to the performance of the current satellite-borne 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 Conduct universal surveillance around the world instead of conducting high-frequency revisits at a certain point..."
"In short, achieving 24-hour uninterrupted reconnaissance and surveillance around our country is as difficult as targeting any point in the world. It’s the same as conducting 24-hour uninterrupted reconnaissance and surveillance..."
"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 altitude is too high and requires very advanced imaging equipment... This type of equipment has almost no demand except for military use, and The core components are monopolized by the Americans. Even if we have good relations with Europe, it will be difficult to obtain finished products.”
“In addition, even if the equipment problem is really solved, it will still require a very large size. Satellites can be carried, and a large energy supply is required, and the weight will also 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, it will require more than A heavy rocket that is much larger than Triple B..."
"..."
Obviously, although China has developed quite rapidly in recent years, in the face of this systematic backwardness , it is still not something that can be recovered casually.
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 range of 500-1,000 tons have begun to be demonstrated. It is estimated that the project will be approved soon. I dare not say 20 tons, but in the future it will be launched on the earth. It shouldn’t be a big problem to put a 15-ton object on the synchronous orbit..."
Chen Da said frankly that you are coaxing children here. From the beginning of demonstration to the completion of research and development, it is normal to have more than ten years in between. ’s...
But when the words came to his mouth, he looked at Chang Haonan who was standing beside him with his head bowed and said nothing, 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 space-borne 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 from the specialized ocean reconnaissance satellite, we can use the extra space and power supply to install a gazer. The device...is similar to a human neck...er...or an owl's neck."
Chang Haonan felt that it might not be intuitive just by using language, so he asked a staff member next to him for a piece of paper. , Xie Xuan drew a schematic diagram with a few strokes:
“The shooting angle can be adjusted while the satellite itself is not moving. In this way, the effective reconnaissance time provided by one satellite will be greatly improved, and the number of satellites required can also be increased. Reduced to...probably a single digit level.”
