Chapter 1613: Everything is ready

So the first question: If you decide to refit the "Varyag" immediately, how long will it take from the start of construction preparations to the completion of the refitting of the ship?
Zhu Yingfu, a leading ship expert in China, gave his estimate that under current conditions, it will take about 5 to 6 years.
Because after such a long time of preparation, Zhu Yingfu believes that Hanyang has thoroughly understood the entire structure of the ship, and after extensive research on industrial enterprises across the country, he believes that with China’s current basic industry and material capabilities, there is no longer anything. There are technical difficulties that cannot be solved, but many sub-systems are developed for the first time. For the first time to do such a large comprehensive system project involving a wide range of areas, everything needs to be advanced carefully and gradually, so the progress should be placed second Position, and security and quality should be the first priority.
It can also be seen from his answer that the Hanyang Institute had already done a lot of preliminary preparations to complete the construction of the "Varyang".
The second question: How long does it take for "JH-7BH" to complete the verification of all subjects from the first flight to finalization?
Tan Zhenhua said that due to the most critical ski jump take-off-the blocking landing mode is a huge challenge for China's entire engineering field. In order to be as stable as possible, it will take 4 to 5 years, which is more than the subject of land-based fighters. The test flight takes longer.
This seems to be walking with the timetable again!
If Tan Xiaozi hadn't been planning the layout long ago, who would believe it?
By this time, all the participants including General Liu had understood that the taste was coming. It turned out that Tan Zhenhua started preparations for today’s meeting many years ago. Now, he is just notifying the results of his preparations. Everyone, let me tell you by the way: everything is ready, only the wind is owed.
There is one last question: "Varyag" is a medium-sized aircraft carrier with a displacement of 60,000 tons and adopts a skid-jump take-off-stop landing mode. The power system adopted is a high-pressure steam turbine, which is in line with what Tan Zhenhua himself just said repeatedly. "China wants to develop nuclear-powered aircraft carriers, or at least conventionally-powered large aircraft carriers." The direction is not consistent, but now it has shown with practical actions that he wants to build the "Varyag". Isn't this a contradiction? why?
"Because of ability and cost." Tan Zhenhua answered this question.
"Aircraft carrier, it is undoubtedly a powerful weapon, but no matter how powerful a weapon is, there is no guarantee that it will not suffer losses in war. For example, in World War II, a "midway naval battle" cost the Wa country. 4 aircraft carriers, resulting in the loss of its navy’s elite forces. As a result, in the subsequent "Mariana Battle", the largest aircraft carrier battle in human history, it was almost impossible to cause substantial damage to the US fleet. Threats, the Americans even jokingly called this naval battle the "Mariana Turkey Hunting Tournament". Today we will not discuss the gains and losses of the parties in the two successive battles, but one thing is certain: the reason why the Americans can easily win In addition to the correct tactics and good luck of the battlefield commander, it is also very important that the Americans had the most powerful industrial capabilities in the world at that time! You know, in the "Mariana Battle", the Americans 15 aircraft carriers were dispatched, compared with the last remaining three aircraft carriers of the Japanese, this is simply a crushing advantage!"
General Liu nodded and said: "Zhenhua, I agree with you. In war, logistics is to a large extent. This logistics, of course, also includes the ability to replenish the equipment after damage, so what do you mean?"
"Large-scale aircraft carriers that use ejection devices have high combat effectiveness, but they are also difficult to build, especially the ejection devices on them. This system requires complicated boilers and steam pipelines. It is very difficult to develop, install, use, and maintain. Troublesome, Director Zhu should have a deep understanding of this."
Zhu Yingfu nodded and was deeply impressed by Tan Zhenhua's statement-as far as the mid-1980s, when the "Melbourne" was towed to Huaxia for dismantling operations, Tan Zhenhua surreptitiously removed from the scrap steel recycling company in Austria. In China, a lot of pipes, boilers, etc., hundreds of tons of "garbage" were recovered. It is said that a lot of connections and a lot of money were spent on this.
This large pile of "scrap steel" was transported to China, but Zhu Yingfu was like a treasure-steam catapult, which is not complicated in principle, but it is quite difficult in engineering to realize it. However, before China, There is also no accumulation. Starting from scratch to explore and research means that a lot of manpower and material resources need to be invested, and it will inevitably step into countless "pits" to pay tuition, and there is a set of ready-made samples. , This help is undoubtedly extremely huge.
Therefore, the Hanyang Shipbuilding Institute quickly restored this dismantled system by several companies specializing in steam boiler research in the United Nations, and on this basis, invested efforts to carry out multiple directions. Analysis and research. As of today, this research has been carried out for 11 years and has achieved a series of breakthroughs. The Hanyang Institute is planning to declare a key project to the state and plan to build a test device on land to verify the entire system. The actual working ability and reliability.
Therefore, Zhu Yingfu can be said to have a good understanding of the steam ejection system and the difficulties involved. It is no exaggeration to say that this system is the most technical system on the aircraft carrier, which is comparable to building a 60,000-ton displacement ship. The shell is much more difficult, and the deployment of the entire system is extremely time-consuming, labor-intensive, and extremely expensive.
"In comparison, an aircraft carrier without a catapult device, like the "Varyag", can greatly reduce the cost during construction and the construction efficiency can also be greatly improved. With our existing ship building capabilities With the ability to support the supply chain system, after the implementation of the project to rebuild the "Varyag", it should be possible to manufacture similar ships in large-scale batches with very high efficiency. I personally think that with this ability, we are in China. What we must have in response to emergencies. In other words, in the future, China may use less or no use of aircraft carriers like the "Varyag", but we must have the ability to build it on a large scale in the short term."
Once again, Admiral Liu nodded slightly. At the same time, he appreciated Tan Zhenhua’s in-depth and long-term view of the problem. It’s no accident that this kid can have today’s success. He really took one step and looked at three steps and five steps. Ten steps a hundred steps!
Of course Zhu Yingfu was also nodding his head, but immediately afterwards, he thought of another important issue.
