"Although it is quite different from the destroyers I have known in the past, overall, it looks good." Makino Shigeru only commented.

It is said that the full-load displacement is more than 5000 tons, but in fact, the weapons and equipment can only be arranged according to the body of a modern destroyer of 4000 to 4500 tons-the steam turbine takes up too much space.However, considering that the United States was still building the Adams-class and Farragut-class steam turbines in the late 50s, the power system of the new destroyer was not too far behind. Super small.

Li Qiang: "The core equipment of the new drive is it. Because it is installed and other new equipment, the generator set of the new drive, in addition to two turbine generators, also needs to be equipped with 4 high-speed diesel engines instead of the current one. Two of the Type 56 destroyers."

Li Qiang pointed to the mast tower between the two chimneys in the center of the hull.The top of the mast tower is a slab placed obliquely, and it seems that the slab is not small.

This is a three-coordinate air search radar developed by Hangdian-Hangzhou Radar Electronics Institute. G band, full digital integration of circuits, one-dimensional phase-scanning pulse signal system, phased array technology for in-plane scanning at elevation angles, the maximum detection distance is 280 kilometers, and the maximum number of target tracking is 10-20 (depending on the memory and processing of the control computer ability).

Tang Hua: "Lao Li, thank you for your hard work. We can see the Type 307 radar so quickly."

Li Qiang: "Hangdian and Nandian have a very high starting point. It is not too difficult to make further progress on this basis. However, the official version of the data processing and control computer will have to wait until next year, and the problem of high-power forward wave tubes must be solved. .”

Now radars are all three-digit numbers, the first digit indicates the platform, 1 is ground-based radar, 2 is airborne radar, 3 is shipboard radar, 4 is space radar...

307 is the seventh type of shipborne radar. Four of the previous types of radars were built by borrowing a certain type of Soviet-made radar components, and two were newly developed. The 7 radar did not have a Soviet model as a reference. When the development was started in 307, it was Tang Hua who set the design direction according to the general appearance of the 1953 radar.

Since Li Qiang took over as the director of the Electronic Information Industry Bureau in 1954, he has been active around Shanghai for at least eight months a year, mainly focusing on the development of radars, radio systems, and electronic countermeasure systems in Shanghai and surrounding units.

李强和唐华一人一句聊了一会儿，牧野茂则在看307雷达的技术参数。看到最大探测距离280公里、波束从0度平视改到30度仰视只需要1毫秒、最多能同时跟踪10~20个空中目标时，惊讶得很。

"Such a single destroyer can control the airspace of the entire theater," Makino said.

除了中后部桅塔塔的307雷达，舰桥顶端的308型低空/对海搜索雷达也是个新雷达，是305的改进型。在308雷达的前面、比308雷达低一层的地方，是309雷达。这样的照射雷达在舰后部的高台上还有一部。

"This is a Type 309 target irradiation radar. Its function is to track and illuminate air targets and guide the HQ-6 missile attack."

There are two launching devices for Hongqi-6, one on the platform behind the main gun at the bow and one at the stern.Because the shipboard helicopter does not know when it will be available, so the rear deck is also used.

……

"The overall technical overview is like this. The whole ship is equipped with one 1mm single-tube main gun, two high-firing cannons, two double-mounted ship-to-air missiles/combined launchers, and two quadruple-mounted Eagle-100/ The long sword-2 missile launcher, in general, is a multi-functional destroyer that focuses on air and takes into account anti-ship and anti-submarine."

"Four of the six main components are still under development, and the latest one will be in place around 6, so starting construction in the middle or end of 1960 will not affect the schedule of the entire construction plan."

Tang Hua finally summed up the situation of the new drive.

Li Qiang added: "As part of the research and development work, I hope to experimentally install Type 3 and Type 4 radars on the third and fourth destroyers that have started construction in China. It will greatly improve the comprehensive capabilities of the two Type 307 destroyers."

Cheng Wang: "Minister Tang said just now that the 307 radar consumes a lot of power. If it is installed on a Type 56 destroyer, will it cause insufficient power supply on the ship?"

Makino Shigeru: "If this is the case, I can make limited modifications to the Type 56 hull and add another diesel generator."

……

In addition to the next-generation destroyer, the Ship Design Institute also has an improved design after the localization of the Type 01 frigate, and a multi-functional improvement after the successful imitation of the Soviet-made hunting submarine. However, the Ship Design Institute does not undertake the small boat project now.

In 1950, the Navy formulated the "flying submersible fast" troika pattern, and aircraft and submarines were still the key development targets, and "fast" was gradually marginalized.

But that doesn't mean speedboats aren't built anymore.Now the three major fleets all have speedboat detachments, with one large missile boat brigade and two small missile boat brigades under their jurisdiction. The leader of the speedboat brigade is a Type 1 frigate.

The number of various missile speedboats has now reached 60-70, and will soon be full.After reaching full strength, the navy will not expand the establishment of the missile speedboat force for the time being.

The naval aviation has grown to six aviation divisions. In January 6, the third naval and aviation base in Taiwan was completed. The Tu-1956 that took off from Taiwan can theoretically cover Guam—of course, it is only calculated from the voyage. If you fly over like this, you will be molested by the US Air Force all the way.

"What? A small ammonium bicarbonate plant is being built near Shanghai? Two at the same time?"

Seeing the documents from the Chemical Industry Bureau, Tang Hua thought that he had to ask Peng Tao from the Chemical Industry Bureau for details.

"Minister Tang, our first and second batches of ammonium bicarbonate fertilizer plants are given priority to construction in mountainous areas and counties and cities in large agricultural provinces. The first batch has 13 plants, and the second batch has 27 plants. Shanghai is the third batch. , The construction started in January this year. But you know the industrial foundation of Shanghai, the Ministry of Heavy Industry started the construction one by one, and the Shanghai Municipal Government started it in a hurry, and it may be put into operation earlier than some second batch of factories.”

Tang Hua let out an oh. "In this way, if a developed city builds a small ammonium bicarbonate plant for the suburbs, it should be listed separately from the national plan. The national ammonium bicarbonate plant is built in those areas where the local people cannot afford to invest in the construction of the plant. These big cities use their own The local government does not need to invest much money in the construction of chemical fertilizer plants, so it should be relaxed, as long as it does not exceed the annual output of our ammonia synthesis equipment, let them build it."

Peng Tao: "Agriculture around well-developed big cities will also benefit from the city, and it is generally very developed. I went to the urea complex plant in Nanjing not long ago. Not only the agriculture has benefited there, but even the employees of the fertilizer plant and their relatives have benefited. All chickens and dogs ascend to heaven."

Tang Hua: "I know something about this. The urea plant allocates 5% of the share to the factory workers to distribute independently. This was decided in early January this year."

After the bumper summer grain harvest in 1955, the urea produced by the chemical fertilizer plant was never put into storage, and it would definitely be removed within a week of production.

The big and small leaders and workers of the five major urea bases have become celebrities with a radius of ten miles. From time to time, you can see relatives of the workers visiting with special products from their hometowns, and they will definitely ask more questions: "San Yazi, you Does the factory have that, the fertilizer index?"

After the state subsidizes the retail price of chemical fertilizers, spreading chemical fertilizers on the ground will definitely make money. After the state subsidizes the 200 yuan fertilizer, it will only sell for 100 yuan. As long as the fertilizer is used correctly, it can increase the harvest by 160 to 180 yuan.

Fertilizers from urea production bases are given priority to communes that have completed agricultural cooperatives, but not all fertilizers are directly distributed to communes, and a considerable part is still sold, either into the supply and marketing cooperative system, or directly sold.

The part that is sold directly also receives state subsidies, which is okay. As long as the fertilizers are used in the fields and the grain income increases, the entire country’s economy will run better, and the chief accountant is willing to pay such subsidies.

Workers distribute small batches of urea purchase shares. This is to consider that instead of turning "running relationships and fertilizer quotas" into a gray interest chain, it is better to allocate certain fertilizer quotas to factory workers from the very beginning. After all, the N-generation workers now There are very few families. Most of the workers have been farmers for three generations, and there are a lot of distant relatives in the family.

Therefore, a few months after the "fertilizer fever" appeared, the Ministry of Heavy Industry proposed and approved by the State Council, the 5% discretionary fertilizer quota for urea plants was set in this way.

Don't underestimate the 5% index. The urea production line is an efficient and automated production line. The entire synthetic ammonia-urea production base has a large factory area, but there are only 1270 workers in total.If distributed evenly by head, each worker can decide where 4 tons of fertilizer goes.

Of course, the factory has to use some of this 5% to support urban construction in the surrounding countryside. In addition, it is the vegetable farmers who are closely related to the factory canteen... In the end, each worker has 2 tons of chemical fertilizers per year.

……

"Let's talk about the ammonium bicarbonate plant," Tang Hua said. "The first batch of ammonium bicarbonate plants started construction in August last year. Are any of them put into operation now?"

"Two are in production, one in... Tieling and the other in Taiyuan."

Tang Hua: "They started production in February and March, just in time for the maximum amount of chemical fertilizers, but in a few months, there will be a period of time near and after harvesting, and there will not be much demand for chemical fertilizers. At that time, the factory will Whether to consider short-term storage after production, or to distribute fertilizers in a targeted manner, this problem needs to be solved by writing an investigation report for each small ammonium bicarbonate factory.”

Peng Tao: "When planting different crops, the time for sowing and harvesting is different; if the planting cycle is different, the time period for chemical fertilizers is also different. What you mean is to make an optimal mix so that each small chemical fertilizer factory produces Ammonium bicarbonate has the shortest average storage time?"

"Yes. Fertilizer factory... Forget it, the managers of the fertilizer factory can only count the crop types in the surrounding farmland, and the optimization plan will be done by the Ministry of Chemical Industry or the Ministry of Agriculture."

……

The spring plowing in 1956 was like this, and the communes in many places spent it in the battle for fertilizer.

In fact, Tang Hua hopes that before the spring plowing, the south will also start scrambling for small walking tractors.However, from August last year to February this year, Changsha Tractor Factory only produced 8 walk-behind tractors—the construction of the factory has not yet been fully completed.

The number of walking tractors in the hilly rice fields in the south exceeded 10 million at its peak. Based on a 100-year service life, 2 million tractors would be supplied each year... This is too far ahead.The currently planned three walking tractor factories in Wuhan, Changsha and Chongqing have an annual production capacity of [-] units each, respectively.

It reached the design capacity in 1957~1958.

What can 6 tractors do? It is specially prepared for certain special situations, such as a regional rinderpest that causes a large number of cattle to die in a township or even a county. At this time, the country still has a way to save the county’s agriculture.
