Rebirth of the 1980s: The Military Industry Empire

Old Wu laughed and said, "General Qin, I am currently responsible for this project. However, now that your Factory 960 is taking over, I suppose I can retire to the second line and wait for you to develop this missile."

"Old Wu, you still need to be in command. Our Factory 960 will assist you," Qin Yang quickly said modestly.

"See? Old Liu, you've wasted your effort. You don't need to introduce us. General Qin can recognize us," Old Wu said.

Qin Yang was a little helpless. Just now, he had indeed forgotten and directly said Old Wu's name. But now that he had already said it, Qin Yang didn't need to quibble and could admit it generously.

"Yes, I've heard of Old Wu. Old Wu, let's continue talking about the Hongqi-9 missile. This missile project is related to the equipment of the navy and air force, but it is said to be very difficult."

"Yes," Old Wu nodded. "High-altitude, high-speed and ultra-low-altitude penetration are originally two different aspects. It is very difficult to have both of these capabilities in the same air defense missile. Even the British don't have this ability."

In the early 1980s, the East was very interested in the Sea Dart air defense missile equipped on the British Type 42 destroyers, and repeatedly wanted to introduce it to equip its own warships. This modified warship was named 051S, representing a professional air defense ship.

However, it was later learned that although the Sea Dart claimed to be able to hit seventy kilometers, it did not have the ability to intercept anti-ship missiles flying at ultra-low altitude. In the Falklands War, it performed poorly and achieved almost no results. Therefore, the Sea Dart was completely abandoned.

Relying on others is not as good as relying on oneself. We still have to rely on ourselves to solve these problems. But how should we proceed?

Since General Qin wants to intervene, he must have a solution.

"Yes, according to our plan, if we want to achieve a range of about 100 kilometers, the weight of the missile must be more than 1.5 tons, or even 2 tons. With such a heavy missile, where is the maneuverability?"

The primary problem facing everyone is how to make a huge missile intercept ultra-low-altitude sea-skimming anti-ship missiles. Currently, the two projects have been merged into one, and all indicators must be achieved.

"This requires a sufficiently high speed, removing all the missile wings in the middle of the missile body, and only retaining the tail wings," Qin Yang said.

When surface-to-air missiles first appeared, they generally had four large swept-back trapezoidal missile wings in the front and four small missile wings in the rear. The American Hawk missile was like this. Later, with the improvement of technology, it was generally a layout of four missile wings in the front and four missile wings in the back. The old Maozi even turned the trapezoidal missile wings in the front into long strip-shaped side strips.

The main task of the front missile wings is to provide lift. After all, missiles need upward lift to fly in the sky without falling. However, as the missile speed becomes faster and faster, the lift of the missile wings is no longer necessary. The missile body alone can obtain a sufficiently high lift.

In this way, the surface of the missile body is smooth, with only tail wings, and the resistance will be greatly reduced, and the range will be rapidly developed.

This can be seen in the development history of the Hongqi-16 in Qin Yang's original time and space. At the beginning, the appearance was the same as the Shtil missile, and the range was only about 20 kilometers. Later, the guidance method was changed. It flew a high trajectory first, flew over and then aimed at the target. The other things remained the same, and the range was increased to 40 kilometers. Later, the length of the missile body was increased, and the range was increased to 75 kilometers. This kind of medium-range missile began to steal the work of long-range missiles.

Later, this missile continued to develop. The side strips on the outside were removed, only the tail wings were retained, the active radar seeker was replaced, and the trajectory was optimized. The range suddenly increased to 160 kilometers!

Think about it. When the Hongqi-9 first came out, it was just a missile with a range of about 100 kilometers. As a result, it was overshadowed by a medium-range missile. However, the Hongqi-9 was not idle either. It continued to upgrade, and the range exceeded 200 kilometers. The self-use one was even heading for 400 kilometers.

The increase in range must have the credit of the propellant, but it also has the credit of the appearance.

Now, if you want to use existing technology to develop a missile with a range of 100 kilometers, the design of the appearance must be done well.

"Only tail wings?"

"Yes, only tail wings, the area should not be too large, so that the resistance can be greatly reduced. If it is done well, perhaps the range can be increased by half without changing anything else."

"That's right, if designed in this way, the range can indeed be greatly increased, but General Qin, the maneuverability of the missile is not high if designed in this way. It is even more inconvenient, especially when attacking ultra-low-altitude sea-skimming targets."

With only four rudder surfaces and a small rudder surface area, can the maneuverability of such a missile be high?

"Gas rudder."

For attacking sea-skimming targets, a gas rudder is the best choice.

Previous missiles have always used rudder surfaces to control the maneuverability of the missile, and the efficiency of the rudder surface is greatly related to the speed. The faster the speed, the greater the aerodynamic torque of the rudder surface. When the missile has just flown out, the speed has not yet increased. At this time, the efficiency of the aerodynamic rudder surface is very low, and it is difficult to turn quickly. For vertically launched missiles, this is almost an unsolvable problem.

Previous missiles were launched obliquely. Before launching, the launcher would rotate to aim at the direction from which the target was coming. After the missile flew out, it could directly pounce on the target.

However, oblique launch has ammunition limitations and cannot resist saturation attacks. Therefore, the new generation of weapons is mainly vertical launch. How many missiles can a warship carry can be launched together.

No matter which direction the target flies from, the missile can turn to that direction and launch an attack. This is the advantage and disadvantage of vertical launch. When the target is too close, it needs to turn around and dive after being launched from the launch tube. At this time, it is not as fast as oblique launch.

If there is no early warning aircraft, the distance at which a warship itself can detect ultra-low-altitude sea-skimming anti-ship missiles will not be too far. Even if the radar is placed at the highest point, it is not easy to detect it beyond 30 kilometers. If the waves are high, it may be detected within 20 kilometers. Therefore, at most, it can only be intercepted once. If it doesn't work, it has to be handed over to close-in defense. If close-in defense doesn't stop it, it has to be resisted hard.
