Ballistic Silence of Special Years

Chapter 1329 SJ-21 Plan

Standing in front of the huge electronic screen, Li Zheng's focus was temporarily on the west.

He never expected that the confrontation system would give such a complicated situation.

Although he had predicted and deduced all the most complicated situations before the red-blue confrontation, White's participation still made him feel pressured.

This battle is not easy to fight.

Dealing with two fronts at the same time is no joke.

If you make one wrong move, the whole situation will collapse.

Facing the upcoming blow from the blue side, the red side's counterattack was relatively weak in a short period of time.

It takes at least 36 hours.

DN-3 has begun to be launched one after another, but it will take time to destroy the opponent's GPS system satellites and spy satellites.

It will take at least 24-36 hours for the opponent's GPS to fail and for the arm-wrestling to return to the same level.

In fact, the loss of the Beidou system is only part of the decline in combat effectiveness. The blue side and the yellow side also took action against the red side's high-scoring satellites.

The destroyed satellites also included many reconnaissance satellites.

There are many such satellites on both sides, and even if they are not dedicated to military use, some civilian satellites can temporarily take over this role.

It's just that this substitution is not as useful as the combination of Beidou and reconnaissance satellites.

The loss of the Beidou satellite does not mean that the red side has completely lost its missile attack capability, because the precise guidance of the missile does not only rely on navigation and positioning, but also has inertial positioning and other modes. However, the accuracy will be reduced, and the attack movement will be reduced. It's more of a disadvantage when it comes to goals.

All active missiles are basically equipped with inertial navigation devices. This is the most stable and least susceptible to interference. Especially on strategic-level missiles, there must be such a thing, because for strategic-level missiles For missiles, the error of a few hundred meters or even a thousand meters is not a big problem. Anyway, if one hits it, it will flatten it.

To understand the impact of satellite navigation on the accuracy of missile attacks, we must understand the guidance methods of modern missile attacks.

Take the most common cruise missile as an example. Its guidance methods generally include inertial navigation in the initial stage of flight, inertial navigation + terrain matching + satellite navigation in the middle stage of flight, and platform inertial navigation + scene matching navigation in the final stage of flight. For example, the most modified guidance method of the blue team's "Tomahawk" land-attack cruise missile is an inertial navigation system + terrain matching + digital scene matching IV + global positioning system + precise terrain-assisted navigation (meter level), with a range of 2500 kilometers, the circular probability error is only 10 meters.

If the Global Positioning System (GPS) is removed, the error will not be ten meters, but perhaps tens of meters, or even hundreds of meters.

This is the impact of satellites.

As for the loss of reconnaissance satellites, it means the loss of the ability to monitor battlefield trends at any time, discover enemies, and conduct on-site assessments after tactical attacks. This also affects the tactical decision-making and response capabilities of the command level.

At present, the three parties of red, blue and yellow have entered into the capability of constantly destroying each other.

After all, the three parties still have a lot of satellites in outer space, and they will not be able to attack them all in a while. Even the standard series missiles used by the yellow and blue parties have a stockpile quantity, and the standard series missiles can only attack satellites in low orbits. The medium and high rail needs X37B to complete.

However, the X37B is just an aircraft after all. It requires a heavy-duty Falcon rocket to be launched up. After getting up, it has to get close to the satellite, and only after it gets close can it attack.

Although the red side has many anti-satellite means, if it is simple, direct and crude, then just use the DN-3. The highest range of this thing can reach 36000 kilometers. One weapon can meet all needs.

In terms of means, the red side's attack is more severe.

However, it means that the red side has the advantage in this space anti-satellite contest.

The reason is quantity.

Judging from the number of satellites, Blue Star currently has a total of 4500 satellites in outer space orbit, of which Blue Star alone accounts for 2944, which is more than half of the total. The red side currently has only 499 satellites in orbit, which is not of the same level in terms of number.

However, 2944 of Blue's 2500 satellites are for commercial use, and only a few hundred are used for military purposes.

Sound less?

No.

Because even Blue Fang's commercial satellites can be used for military purposes in times of emergency. For example, Gou Ge's satellites, which are usually used to make map systems, can also be converted to military use and used as reconnaissance satellites for surveillance purposes. use.

In terms of attack methods, the red side has the advantage; in the number of satellites, the blue side has the advantage.

Therefore, Li Zheng decided to attack the opponent's navigation satellites first. There were only 24 of them, and it could be done in more than a day.

Then quickly replenish stars and compare consumption with the blue side.

At the same time, the aerospace technology department also proposed a more cost-effective and labor-saving countermeasure to the Joint Staff - launching its most advanced "SJ-21" satellite.

"SJ-21", also known as Practice , is a project called a "space trailer".

66 years have passed since Zi Fang successfully launched the first artificial satellite on Blue Star into space. During this period, human space activities produced billions of space debris, also known as space junk.

These space wastes continue to collide and decompose with each other in the earth's orbit, producing more small fragments, making the space debris problem increasingly serious.

They travel at extremely high speeds in the Earth's orbit. Even small fragments that collide with orbiting satellites or spacecraft can cause serious damage to global communication networks, weather forecast systems, positioning systems and other important satellite services. All pose a serious threat.

Therefore, there is an urgent need for space debris cleanup by all parties.

Although Blue Fang proposed the concept of a space tug in the 1950s, it uses one satellite to capture another satellite through technical means and move it out of orbit.

However, the blue team has not made much technical progress in this area since then.

Surprisingly, the Red Team finally achieved this goal.

On June 16, 6, the red side successfully launched a technology test satellite named "Aolong-25".

What makes it special is the ability to have a robotic arm that can grab abandoned satellites and space debris and introduce them into the atmosphere for burning.

As time passed, the red side continued to work hard and successfully launched a satellite named "Jiushi 21 (SJ-21)" in 21.

This satellite has become even more interesting. Not only can it accurately position and adjust its orbit freely, it is also equipped with a set of space debris cleaning equipment, such as flying nets, mechanical claws or mechanical arms, which can clean up dangerous space debris.

In January 22, the satellite successfully removed a failed Beidou-2 G2 navigation satellite from the crowded geosynchronous orbit and dragged it to a "cemetery orbit" nearly 1.5 kilometers from the earth.

In other words, the SJ-21 satellite is a satellite that can cruise in outer space for a long time, constantly patrol and capture other satellites. You can call it a "trailer" or a "predator".

The method of using satellites to capture satellites is more cost-effective. Secondly, this thing is equivalent to a patrol, which can be activated at any time in orbit. Even if the blue team launches satellites to replenish the stars, they will probably be caught by SJ-21 before they can adjust their posture. , directly tow or destroy.

What the aerospace technology department means is to launch at least 30 such satellites so that they can directly block the space orbit!

　Asking for a monthly ticket!
