Chapter 1243 Elbow, come into the house with me! (New January, please vote~)

At the same time, Beijing.

Chang Haonan, who had just taken a shower and changed into pajamas, was sitting on the sofa, watching the conference being broadcast on the international channel on TV, and writing and drawing on a piece of paper with the pencil in his hand.

The other party would use an interception mission as a response to the previous missile test. This was part of his calculations.

But it is indeed a bit unexpected to directly choose to launch satellites in one step.

In the previous life, Standard 3 also conducted an anti-satellite interception test in 2008, but the target was a reconnaissance satellite that quickly went out of control after launch.

Now, due to a strange combination of circumstances, similar events have been brought forward two years.

Of course, whether this kind of thing succeeds or fails, it is impossible to really scare Chang Haonan.

But the problem is that the interception plan just announced by NASA is really too extreme...

At this moment, there was a sound of light footsteps behind Chang Haonan.

What followed was a lazy voice with a hint of helplessness:

"Why are you still thinking about watching the news at this time..."

The only one who can still appear at home at this time is Yao Mengna.

To be honest, Chang Haonan is still not used to the sudden addition of a mistress in the house.

After all, it's only been less than a week.

Both are still trying to adapt to their roles.

Before the words were spoken, the person had arrived.

I don't know if it was the fragrance of shower gel or shampoo lingering around the sofa, making Chang Haonan's nose feel a little itchy.

Immediately afterwards, a few wet hair tips fell down on the back of his neck and ears, and flicked slightly with the movements of the person behind him.

Yao Mengna leaned behind Chang Haonan across the back of the sofa, wrapped her arms around her newlywed husband's neck, and gently rested her chin on his head.

But Chang Haonan seemed to still be staring at the TV screen in front of him.

Although I feel angry and funny about this scene, after all, it was my choice, so what can I do...

I had to forgive him.

Furthermore, wasn't the reason why I was attracted to him in the first place precisely because of the way he looked at work seriously?

Thinking of this, Yao Mengna also turned her attention to the distant screen:

"NASA press conference?"

"yes."

With his lover so clingy, even Chang Haonan cannot continue to immerse himself in calculations.

So he simply put down the pen, gently opened the ten slender jade fingers that the senior sister had placed in front of him, then folded his two hands together and gently held them in his palm:

"Last month's test launch of an intermediate-range missile caused a much greater reaction than I expected..."

he explained patiently.

At the same time, his upper body was slightly backward, his head was half raised, and he was looking at the delicate profile of his wife in front of him, as well as the soft and graceful, yet angular jawline.

I couldn't help it and pecked it lightly.

"ah-"

The sudden attack without warning scared the people behind him and subconsciously wanted to straighten up.

Chang Haonan's head also hit a place because of this.

Fortunately it doesn't hurt much.

Soon, the two of them returned to their previous positions, but Chang Haonan could clearly feel that the cheek against the top of his head was slightly hot.

"But...what does this have to do with NASA?"

Yao Mengna, who was blushing, took the initiative to change the topic.

It was just after nine o'clock in the evening, and it was really not time to go to bed.

But if it was in the living room...she really couldn't accept it.

Fortunately, Chang Haonan didn't mean this, and just explained:

"They are planning to intercept a satellite in the name of ensuring ground safety. Its orbital altitude is not much different from that of an intermediate-range missile."

Yao Mengna may have heard some fragmentary information about the test firing of hypersonic verification bombs, but she is not really an insider.

Therefore, even at home, we can only speak in the name of medium-range ballistic missiles.

"Doesn't that mean... it's at least 400-500 kilometers high?"

Yao Mengna has been focusing on aircraft structure calculation and production efficiency optimization in recent years. She can only say that she has some understanding of missiles, but not much:

"Can anti-aircraft missiles reach such a height?"

She was partly genuinely curious, partly because she had nothing to talk about. As she asked, she didn't forget to take a piece of hair and sweep it back and forth at the tip of Chang Haonan's nose.

“General models really don’t work…”

Chang Haonan stretched his arms back and hugged his wife's waist wrapped in nightgown:

Originally I just wanted to leave it like that, but my right hand happened to touch the opening on the side of the skirt...

So I subconsciously explored...

"Um…"

Yao Mengna snorted, quickly retracted her arm, and held Chang Haonan's hand firmly through her nightgown.

"Go on."

Chang Haonan felt the warmth and tenderness coming from his fingertips, as well as a pair of soft pillows that were accidentally pressed against the back of his head, and he exhaled a breath of comfort.

However, he was not prepared to do anything here, so he continued to explain:

"But increasing the booster to increase acceleration, shrinking the missile wings, reducing drag at the expense of giving up aerodynamic performance, and then reducing the warhead to a kinetic energy killer without charge is almost enough."

What he is actually talking about is the general process of changing from standard 2ERblock4 to standard 3block1A.

But Yao Mengna didn't have this concept in her mind, and she was confused at the moment, so she obviously still didn't understand it.

However, she was not prepared to get entangled in such minutiae:

"So...it's a big threat to us?"

"Well...that's not the case."

Chang Haonan moved his right hand dishonestly again, and then replied:

"It should be said that if this kind of thing is faced with a small number of sporadic intermediate missiles, it can indeed guarantee a certain interception rate, but as long as the number is large, nothing will work..."

Anti-ship ballistic missiles are the bait he throws to the Americans, so he naturally does not care about the interception threat of Standard 3.

Of course, I can only say this in my heart.

Yao Mengna behind her was obviously relieved, but her breathing was still a little disordered:

"Then why are you so concerned... Anyway, it's normal for you to come and go."

The interaction between the two was no different from that of an ordinary newlywed couple, but what they said was something special:

"But the problem is that the normal launch height of the Sea-Based Standard 3 is not high enough, so this time they plan to use a direct ascending method to intercept, and at the same time, the satellite adjusts its orbit..."

Chang Haonan felt that it was a bit tiring to maintain the current posture. Considering that it would be useful later, he took the initiative to leave, took Yao Mengna's hand and pulled it to the other side, gesturing for the other party to come around to him.

But Yao Mengna was not going to take a detour at all. She crossed the back of the sofa with her long legs and sat directly next to Chang Haonan.

The latter has become accustomed to his wife's behavior in the past few days, and without too many surprises, he just picked up the piece of paper on the coffee table:

"The post-impact motion characteristics of the direct ascent type and the common orbit type are different. I just did a casual calculation. If the fault tolerance compensation mechanism at the end is not good enough, it is very likely that some large satellite fragments will be left in space after the impact. , and the orbit cannot be calculated at all, this will be a big trouble..."

"Moreover, their estimated impact height is around 470 kilometers. If you are unlucky...there is a high probability that the debris will collapse to the operating altitude of the spacecraft and space station...Whether from the perspective of competition between countries or space cooperation, I think It is necessary to remind everyone of this risk. Of course, whether the other party will listen is another matter..."

After Chang Haonan finished speaking, he threw the piece of paper back to its original place, and then moved his sore neck.

But he happened to see the tall Yao Mengna lying lazily on her side on the sofa, her body spread out.

A pair of long legs were exposed from the gap in the nightgown. Under the fluorescent lamp, the skin was so white that it was dazzling.

For no reason, Chang Haonan suddenly felt a little itchy.

As if she noticed her husband's gaze, Yao Mengna smiled at the corner of her mouth:

"It's so late today, and it's impossible for others to be in the unit... No matter what happens, we'll talk about it tomorrow."

After saying that, he grabbed Chang Haonan's arm with one hand and pulled him up, and picked up the remote control with the other hand to turn off the TV.

Elbow, follow me into the house!
