The specific details of the domestic affairs are still the responsibility of the domestic people, call and communicate with his father Xu Haoran, and ask him to send someone to negotiate with the Great Wall Company, and Xu Ziling will basically have nothing to do.

On the fourth day after returning to Beijing, Zheng Wenzhong, who had made an appointment with Lu before, talked about the progress of the large aircraft project and some progress after the introduction of the J-15 into the military factory.

They are not here for the launching ceremony of the aircraft carrier ten days later, but for the acceptance of unmanned submarines.

According to the plan, the unmanned submarine should have completed the launch and navigation tests last year, but due to a pair of incidents made by the Mi people in Makula a few years ago, Xu Ziling did not have time to conduct the last test of the automatic operating system, so it has been delayed until now.

Of course, Xu Ziling's lack of time does not necessarily mean that the submarine will not be tested.

During this time, many personnel of the submarine project team did not even go back for the Chinese New Year, and adopted the method of manual driving to launch the submarine for testing.

However, since the main significance of this submarine is unmanned, no matter how smooth the manual piloting is, the unmanned still has to be tested.

Before returning to China, the submarine had already been driven to sea, and it was not until the two days that he returned to Hong Kong, Xu Ziling naturally took this opportunity to get the automatic driving system right and complete the last process before the unmanned submarine was officially launched into service.

Their Gulfstream 550 landed at the military airfield of the South China Sea Fleet, and Tang Jiannian sent Xu Ziling and their old acquaintance to pick them up: Lao Gao of No. 051.

"Lao Gao, it's been a long time." As soon as they got off the plane, Xu Ziling and the others saw Lao Gao and gave him a hug.

"Long time no see, the first few times you came, I had a mission outside, no way." Lao Gao is still the same, and he greeted Xu Ziling and a few of them, and then greeted Yang Ruolan, "My brother and sister are also here, your sister-in-law was still talking about you a while ago, and I will go to my house for dinner next night." ”

"Brother Gao is good!" Yang Ruolan greeted with a smile, but did not answer Lao Gao's suggestion to go to his house for dinner, but looked at Xu Ziling.

Xu Ziling saw her eyes, of course he knew what he meant, and said to Gao Xianxian with a smile: "Old Gao, I'm afraid this is really not good, I have something to do with the people in Jiangnan Factory at night, let's talk about it tomorrow night, and I will talk to my sister-in-law tomorrow night." ”

"Okay...... Okay, ......, I didn't think it through, so it's decided, I'll ask your sister-in-law to get you some authentic seafood tomorrow. Knowing that Xu Ziling was not shirking, Lao Gao smiled heartily.

"No problem, you must go, you just need to prepare good wine and food."

Lao Gao is no longer the captain of No. 051, but has become the latest captain of a new type of ship in service, with the rank of colonel, but despite this, he is not clear about some of the actions of the Jiangnan Factory.

Xu Ziling came here suddenly, he was a little curious, and when he came out of the airport, he asked them what was the matter with this time.

If someone else asked this question, Xu Ziling and they wouldn't necessarily answer, but Lao Gao was an old friend, and they didn't want to hide it from him, "The new submarine here is going to be launched for sea trials, come and have a look." ”

"Got into the water?" He knew about the submarine, and he heard it from Xu Ziling a long time ago, but after that, the Jiangnan Factory was very strict with the news in this regard, and he never heard of any new news in this regard, and now he suddenly heard that he was going to be launched, and he was really surprised.

In his opinion, since the beginning of the project, it has only been a little more than a year, which is a bit incredibly fast.

"That's fast, show me if you can?" The relationship is familiar, and he is not angry, so he immediately asked if he could take him with him.

"What's wrong with that?" Xu Ziling said with a smile, "Tomorrow morning, the official sea trial, you can come over early." ”

"Okay."

The airport is the closest to the headquarters, so Xu Ziling and they went to Tang Jiannian first.

With their relationship with Tang Jiannian, politeness is definitely unnecessary, after chatting for a while, it was almost noon, without a word, Tang Jiannian left them to eat at the headquarters, and Xu Ziling They did not shirk, and immediately agreed.

"How did you get that repair shop?" On the way to the cafeteria, Tang Jiannian asked about the situation in Makula.

Xu Ziling understood that the maintenance plant he was talking about was referring to the base they used to repair warships and aircraft carriers, "Listen to it, the construction will start on the fifth day of the first month, it is originally a deep-water channel, as long as you get a wharf, it is estimated that it will be completed in less than three months." ”

"Well, that's good. People have already prepared it for you, and this month can pass, so you can arrange it when the time comes. ”

If it weren't for the situation in the South China Sea and the country's embarrassing position in the international community, it would not be much use for the military factory to ask for an aircraft carrier, and it was not bad to have its own aircraft carrier formation, and it was also agreed with the country that the conditions would be helped to train the navy from above, but when he went back during the Chinese New Year, the words of several old men in the capital made him dispel this idea.

It has become that the state will directly send someone to take over the aircraft carrier formation, hand over the command to the military factory within five years, and the aircraft carrier will be nationalized after five years, and the expenses of these five years will be borne by the country.

That is, the military factory will give out aircraft carriers and warships, and the state will pay for it, and then let the military factory use it for free for five years.

To tell the truth, the most advanced aircraft carrier of the Mi people, Xu Ziling is a little unsightly, he really wants to have their own aircraft carrier formation, he is still willing to have their own manufacturing, and he doesn't like Mi domestic products, so when he learned that the country had such an idea through a few old men, he immediately agreed.

In his eyes, a pile of broken copper and iron can be exchanged for a fleet to serve him for free for five years, so it's strange if he doesn't want to.

Five years later, according to the development of military factories, they will have enough economic capacity to equip their own aircraft carriers, and at that time, a 100,000-ton aircraft carrier will be considered a fart.

"No problem, the dormitory or something has already been prepared, just go over there."

"Well, I'll let you know when the time comes."

Chatting all the way to the cafeteria, the cooks who had been notified in advance had a table full of good dishes on their tables within five minutes of their sittings.

Xu Ziling ate northern food in the capital, and now he happened to eat a lighter southern food, and he was not polite, so he grabbed his chopsticks and began to eat violently.

They didn't come here to catch up with the old days, of course they wouldn't stay in the South China Sea Fleet for long, and after eating Chinese food and resting for a while, a few people went to the Jiangnan Factory.

Since the reorganization of the Jiangnan Factory, under the management of Yang Ruolan's brother-in-law Zhao Zihua, everything has been in order, if it weren't for the Jiangnan Factory being too important to the military factory, Xu Ziling really didn't want to put him here, because just letting him manage a shipyard is really a bit overkill.

He also discussed with Yang Ruolan about this issue, but he didn't find a suitable candidate to replace him for a while, and the matter dragged on.

Zhao Zihua knew that Xu Ziling and they went to the South China Sea Fleet, but he didn't expect that they would come over just after dinner, and when the office door was opened and a group of people appeared in front of him, he was still very surprised.

"Oops, why are you here at this time, it's so hot." got up and beckoned a few people to hurry into the room, and called the secretary to pour them tea.

"It's okay over there, so I'll come here." Yang Ruolan explained to Zhao Zihua while taking a few bottles of wine and handing them to him.

After living in the United States for many years, Zhao Zihua's habit of drinking red wine is greater than drinking white wine, whether it is Xu Ziling or other juniors coming over, he will always bring one or two bottles to him, and the more times he comes, he will get used to it, take the wine in Yang Ruolan's hand, look at it and put it into the small bar next to him, while chatting with a few people, "I don't know what's wrong with Lu Dao during this time, the temperature is suddenly high, and there are forty degrees up every day these days, so people don't dare to go out." ”

It's only February, but the temperature is as high as 40 degrees, which is indeed a bit abnormal, but they are not meteorological experts, this kind of topic is naturally just casual talk, and after a few words, the topic turned to unmanned submarines.

"I said to test it quickly, and the people from the East China Sea Fleet called again a few days ago to ask, presumably there is an idea to procure." Zhao Zihua told everyone a piece of news that they didn't know.

"Oh, and what's going on?" Xu Ziling and they really don't know about this matter.

"I checked with Commander Tang that it's someone from the East China Sea Fleet." Zhao Zihua was afraid that they would not believe it, so he immediately explained.

"It's not that I'm afraid that someone will impersonate them, but it's a little strange that they will contact this side directly." Xu Ziling shook his head.

The Jiangnan Plant belongs to the military factory, and in his cognition, even if the East China Sea Fleet has the idea of purchasing unmanned submarines, it should contact the military factory, not the Jiangnan Factory.

So it's a little weird.

But this kind of thing doesn't have any effect, and he can't figure it out after thinking about it for a while, so he doesn't think much about it.

"It's a good thing that the East China Sea Fleet has this idea, and I'll improve the control system later, and I'll start sea trials tomorrow."

"Tomorrow? It's so urgent, I said hurry, then there's no need to be in a hurry......"

"The sooner we finish it, the sooner we can sell it."

"That's okay, I'll arrange it later."

After chatting for a while and chatting for a while, Xu Ziling asked Yang Ruolan and Yang Kaiming to go shopping together, and he went to the dock alone, preparing to use the afternoon and evening time to get the control system right.

Unmanned submarines, due to the limitations of computer hardware, cannot be piloted autonomously now, and can only be remotely controlled by people, coupled with the assistance of semi-intelligent systems, to realize the navigation of submarines in the sea.

Originally, in Xu Ziling's idea, whether it is an unmanned aircraft or an unmanned submarine, it is best to have an independent intelligent system, just like a lion controlling a drone, which can be controlled more accurately with people. It's a pity that the intelligent system has high requirements for computer hardware due to computing power, and submarines and airplanes are limited by some other related factors in space, so they can't load supercomputers on them at all, so his plan can only be disappointed.
