The close-in defense weapon system has a very clear goal when it is designed: to shoot down the Eagle Strike-2, the interception probability of a single gun against a single bomb must reach 80%. This single-handed combat mode allows the close-in defense weapon system to have two Opening the firing window, the first shuttle shot out and was not intercepted, and another shuttle could come.
In other words, the interception success rate of a single firing window should be able to reach almost 60%.
鹰击-2的性能就让大连建新公司十分挠头了。到1956年，由于高度仪和控制系统的优化，这弹的巡航高度已经从100米再降到50米，这是一枚在50米高度飞行的、速度0.8马赫、正面投影面积不到0.5平方米的东西。
Dalian Jianxin first tried a dual-mounted 25mm gun, but the interception rate was not good, and it was far behind.
Then, Dalian Jianxin produced a triple-mounted 25mm gun.After that, a quadruple 25mm gun was built.All failed, unable to achieve an effective interception rate.
Dalian Jianxin began to look back and re-examine the entire project, thinking that the automatic machine of the Soviet-made 25mm gun was not good, and the theoretical rate of fire was only 450 rounds per minute, because the bomb feeder was discontinuous, and the actual rate of fire was lower, only more than 200 rounds per minute .
If you want to change it, you can change it. Dalian Lite simply changed all the ammunition. The ammunition was replaced with 30mm high-velocity shells. The theoretical rate of fire reached 900 rounds per minute.
The 30mm gun was installed in a dual mount first, and the test found that the effect was very good, and the interception rate was only a little bit short of the standard.
Then, the quadruple and triple mounts can't be done, because the 30mm gun is too heavy.
When Dalian Jianxin was about to despair, Taiyuan Institute of Mechanical Engineering built a 6-barreled Gatling cannon, which gave Dalian Jianxin a glimpse of the dawn.The only problem is: Taiyuan Institute of Mechanical Engineering is paired with Taiyuan Arsenal.
Fortunately, Liu Nai and Qiu Chuangcheng could coordinate this matter, so the cannon of the near-defense weapon system was determined to be 6-tube Gatling, and the development of the system was also determined to be a Taiyuan-Dalian joint development. other systems.

"In any case, when the Type 58 destroyer goes to sea for sea trials next year, the secondary gun positions will definitely be empty," Tang Hua said, "but don't worry about it. You have to do all the tests that need to be done. Bring the faults to active service. On a warship, it’s more haste than speed.”
"Yes. Our newly established goal is that when the guided missile cruiser goes to sea for sea trials, the secondary battery is installed."
According to the plan of the Jiangnan Shipyard, the Jiangsu ship's sea trial may be at the end of 61 or early 62.
Dalian Jianxin Company was still working on a project with a higher level of security. When Tang Hua entered the work area where the project was located, the first batch of products produced here had already been shipped away, and one-third of the researchers and testers had also left.
"Are they in Beijing now?" Tang Hua asked.
"Yes, the shooting range of the Beijing Military Region."
The reason why the test was placed on the artillery range of the Beijing Military Region is because it is relatively close to Fangshan.
The end user of this product is Qian Sanqiang's group - conventional explosive modules and detonation systems for atomic bombs.
……
On October 10, the day before Tang Hua arrived in Dalian, somewhere in Nankou Town, Changping, Beijing, a 5-meter-high test bench entered the final countdown to the explosion, and all the staff present were evacuated to an underground shelter.
The explosive device on the gantry was a huge spherical ball, nearly 1 meter in diameter.But when the ball was detonated, there was no earth-shattering explosion as imagined.I heard "Boom" on the spot, a very loud sound, but there were no large fireballs or shock waves. The test bench only emitted a flash and a cloud of gunpowder smoke, over.After the smoke cleared, the shelf and the items on the shelf seemed to be still there.
The staff gathered around again, checked the integrity of the platform, and then used a crane to remove the items on the platform. The ball with a diameter of nearly 1 meter had been blown up by explosives and turned into something the size of a basketball.
It took a lot of work to pry open this "basketball", and it took the staff more than ten minutes to carefully take out the test instrument inside and take it back for readings.
"The explosion was very successful?"
Cheng Kaijia was in Baotou, using a secure phone line to talk to Qian Sanqiang.
"Yes, it is very accurate. The synchronization is 100% up to the requirements, and the accuracy of the explosive equivalent and driving force is extremely high." Qian Sanqiang said, "Our No. [-] beast can be assembled next week."
……
The Baotou Nuclear Fuel Component Factory has been put into operation since 1958, and has successively cast and processed nuclear fuel rods for three reactors.But this time, when processing the uranium block for the atomic bomb, the irrelevant personnel in the whole factory area still evacuated, and the staff in the casting workshop also raised their spirits. Everyone's focus was on the small electric furnace in the center of the workshop. .
The nuclear fuel rods are low-enriched uranium with an abundance of 4%. During the melting and casting process, there will be a danger of the crucible polluting the workshop, and there is no danger of causing a nuclear explosion.But this time is different, the uranium 95 with an abundance of 235% is processed.
After uranium 235 is melted, it has one shape in the crucible, another shape when it is poured, and another shape when it is poured into the mold.Well, whether uranium 235 is solid or molten, it is the same. When the critical mass is reached, it will explode when it should explode.
So don’t even think about sending 20kg of uranium 235 powder into it to melt it all together, and then pouring it into 12 molds just like pouring wine...
It has to be processed piece by piece.
From September 9 to October 19, the nerves of more than a dozen staff members in full-body protective clothing in the casting workshop never let up whether they were on or off work. Wang Ganchang, who supervised the battle at the nuclear fuel element factory, was not in the work area, but When the roar of electric current came out from the melting and casting workshop, indicating that the electric furnace had melted another 10 kilograms of uranium, Wang Ganchang, who was 2 meters away, raised his heart in his throat.
On October 10th, all 4 highly enriched uranium blocks that had been processed passed the test. After being tightly packed, they were sent out of the fuel element factory, and then sent by truck to another factory that was also heavily guarded.And the fuel element factory started to manufacture the second atomic bomb, the core of "Monster One", non-stop.
……
Dalian.
On Tang Hua's third day in Dalian, Qian Sanqiang sent a telegram. Although it was a confidential telegram, Lao Qian was still vague. He just said, "Minister Tang is coming back, okay? There is progress and a lot."
The explosives module made in Dalian was an experiment conducted in Beijing, and Qian Sanqiang must have known the results first.
The explosives module was initially tested in Dalian, and it was very successful. It was only tested with more accurate measuring instruments when it was brought to Beijing.From the looks of it, the explosives module has passed the level.
For the atomic bomb, the assembly of the first bomb will start in October.
"Minister Tang, Minister Liu sent a telegram from Shenyang."
Liu Nai also sent a telegram, what are you talking about?
"After discussions and demonstrations by the First Machine Bureau and army representatives, our army's next-generation squad firearms series plan to use 6X43mm small-caliber ammunition."
Chapter 238, Enhanced Monsters
"The No. 0 uranium core will leave the factory on October 10, and it will enter the stage of processing and assembling the implosion core. It is only a matter of time before the No. 4 monster comes out of the cage."
At the research and development base of Fangshan Institute of Atomic Energy, Qian Sanqiang briefly talked about the progress of the first atomic bomb.
Tang Hua nodded: "Monster 0 is a tiger with a pair of wings. If you need code words when communicating by telegram or telephone, organize the code language system according to its monster attributes, which is easier to understand."
Beast No. 0, or Monster No. 0, is named Qiongqi.
Tang Hua also named a large number of code names for the nuclear bombs used in the test explosion in one breath: No. 0 Beast Qiongqi, No. 1 Beast Huntun, No. 2 Beast Wuwu, and No. 3 Beast Taotie.
Next are Tengu, Gu Diao, Xiezhi...
Guo Yonghuai: "Then say this: 'Qongqi's heart is ready, the liver, lungs and six internal organs are being made, and after putting on the tiger skin, it can be released'."
Tang Hua: "When will the cage be needed?" (When will a special train be prepared to transport nuclear bombs)
Qian Sanqiang: "Prepare the cage in December and transport the tiger to Mt. Biao. The monster tower on Mt. Bing will also be completed in December." (Nuclear bombs may be shipped to Lop Nur in December)
"Well, the slang words of both sides of this code communication system are easy to understand," Tang Hua gave a thumbs up, "Old Qian, what you said has made great progress. It shouldn't just be the progress of the No. 0 monster, right?"
Qian Sanqiang: "Well... this... is the problem of strengthening the No. 1 monster."
Deng Jiaxian: "Hundun, we want to put a layer of skin on Hundun."
……
It was only then that Tang Hua discovered that many people in the heavy nuclear reaction team were absent, and less than half of the key members present were present. The light nuclear reaction team was almost full: Deng Jiaxian, Yu Min, Peng Hengwu, Zhou Guangzhao...
"Put lithium deuteride 6 in the fission core, and then wrap a layer of uranium 6 and a neutron reflective layer outside the fission core and lithium deuteride 238?" Tang Hua said, "enhanced atomic bomb. This design is really simple, there is no So many twists and turns."
