Rebirth of the 1980s: The Military Industry Empire

The ocean is so vast that an oil tanker of hundreds of thousands of tons, when entering the ocean, is just a drop in the bucket. Looking at the ocean makes one feel the insignificance of life; nature is the master of this world.

So, how do you find a carrier strike group sailing on the ocean?

In World War II, naval battles started with searching for the enemy. It could be said that as long as you could find the enemy's fleet, you were halfway to success. Both sides would send out a large number of maritime patrol aircraft to search everywhere. These planes usually had three seats: one in the front for flying, and two in the back for searching back and forth.

Now, with the rapid development of military equipment, there are early warning aircraft that can be used to search the sea surface. However, the search area of early warning aircraft is too small to meet the needs. We still have to rely on satellites overhead.

Of course, satellites are not the best either. After all, satellite searches generate massive amounts of data, and the identification of this data is done manually. Satellites take overhead views, and searching for useful data from the images requires long-term training. Due to the lack of sufficient manpower, it is common for useful satellite data to be overlooked.

This problem was not solved until the development of artificial intelligence. Photos taken by satellites are directly given to artificial intelligence for judgment. Computers search for useful information, without missing a single one, and can see everything clearly.

Satellites fly in the sky, and everything below can be found, as if they have a cheat code. No ship will be ignored anymore, and the whereabouts of warships are also clearly visible.

Therefore, countless people are cursing, saying that it will be impossible to sail secretly in the future. This thing is too clever.

Of course, if it comes to wartime, the satellites overhead will be the first to be taken care of, but that's a matter for the future. What we're talking about now is how to attack aircraft carriers, not how to attack satellites.

"And then?" Old Liu asked expectantly.

"Then, it's time for the ballistic missile force to come into play. Various data will be transmitted to the ballistic missile force, providing the missile with launch parameters. Solid-propellant missiles have a very short preparation time and can be launched into the sky within three minutes. Add another eight or nine minutes of flight time, and by the time they re-enter the atmosphere, only a dozen minutes will have passed. In these ten minutes, even if the other side is sailing at full speed, they can only travel five nautical miles."

Ballistic missiles have a very fast flight time. Intercontinental ballistic missiles take about half an hour to fly, while medium-range missiles only need to fly for a dozen minutes from launch to landing. In this time, the other side can't run very far at all.

After all, the maximum speed of an aircraft carrier is only 30 knots, which is only five nautical miles in ten minutes.

Unfortunately, the war has never started.

Qin Yang continued to introduce with this feeling in his heart: "Yes, nuclear bombs are the simplest, but we can't use nuclear bombs. We need to precisely hit the deck of the aircraft carrier. Therefore, when the warhead enters the atmosphere, it must use its belly to contact the atmosphere to decelerate."

When conventional ballistic missiles fall, they should try to reduce resistance as much as possible so that they can reach the target in a shorter time and reduce the other party's reaction time. However, anti-ship ballistic missiles cannot do this.

This kind of anti-ship ballistic missile must decelerate, just like the space shuttle when re-entering the atmosphere, using its belly to contact the air to increase resistance, so as not to become a meteor when entering.

"After decelerating, it is convenient for our warhead to maneuver and fly. After passing through the ionosphere, the radar on our warhead is turned on and starts searching for targets below, preparing for precise correction."

To hit it, you must have high enough accuracy. Although the deck of an American aircraft carrier is more than 300 meters long, it is not easy to hit it accurately.

The Old Maozi (Russians) adopted the principle of passive operation. The guidance head of their R-27K anti-ship ballistic missile has a folding antenna, which will unfold after re-entering the atmosphere, becoming a cross shape, and use this guidance head to sense the electromagnetic waves released by the target, and then find the target to lock on.

This is also the only solution the Old Maozi (Russians) could think of.

After all, there are only so many ways to guide missiles.

Infrared guidance heads were the first to be invented and used in short-range air-to-air missiles. After the missile speed increases, this guidance head cannot be used because the warhead rubs against the air, and its own heat is too high. The guidance head cannot see anything, just like a car turning on its high beams in the dark night, and you can't see anything.

In addition to infrared, there is radar. Radar guidance is divided into active and passive. The Old Maozi (Russians) used passive monitoring, attacking whoever has the largest electromagnetic wave radiation. Of course, if it is a nuclear warhead, as long as you find the fleet through electromagnetic waves and detonate the nuclear bomb above it, everything will be over.

What about our side?

Our side cannot use nuclear bombs, so we must have a more precise method!

"We install radar at the front end of the warhead. In the distance, as long as we can search for the fleet, we can find the target we want to attack based on the echo reflected by the target and launch the final attack," Qin Yang said, "This requires the missile to have the ability to maneuver and change its trajectory, and it must have an advanced computer system to keep up with the reaction speed."

The missile speed is too high. If it cannot react quickly, the trajectory change will always be half a beat slow.

"Radar? What kind of radar?"

"The radar we are preparing for the J-11 can find an aircraft carrier strike group 300 kilometers away. We only need to modify it to use it," Qin Yang said.

What is the principle of the Dongfeng-21D's guidance head? No one knows, and even those who know will definitely not dare to say it. Qin Yang can only speculate based on some information.

It is said that the nose of the J-8II fighter jet was once equipped with this guidance head, and then dived down from high altitude to simulate the characteristics of the Dongfeng-21D to search the sea surface. Although there are many things to discuss in this statement, it also shows that airborne radar can be used on ballistic missiles. After all, both are searching for aircraft carrier strike groups on the sea surface, and only need to filter out sea clutter.

We don't have more advanced equipment at the moment, so we can only use this to experiment.
