20 kilometers away from the destroyer, the A-26 bomber dropped a training bomb of the "Bat" air-to-ship missile. This little dot spewed fire and flew towards the destroyer at a cruising altitude of 300 meters.
A quadruple-mounted 4mm Bofors gun that participated in the test fired ping-pong-pong, and the shells flew towards the sky in strings of tracers.In just 40 seconds, the gun crew's loader actually completed a shell reload, but unfortunately, none of the shells hit.
U.S. Chief of Naval Operations Robert Carney stayed on the bridge of the Keeling-class destroyer USS Gayatt. The "Bat" missile passed over the destroyer unscathed, making a huge roar.The missile was over the top, indicating that the interception failed, and the gunner of the 40mm gun also stopped firing, and there was no need to turn the muzzle and then shoot from the rear.
Robert Carney could not help frowning.
"Whether Bofors or Oerlikon intercept missiles, their interception rate is not very good," said the captain.
Robert Carney: "This is probably what I expected. If Bofors and Oerlikon were effective, the 'Manchester' would not have sunk in the Taiwan Strait."
Captain: "So you should bet your hopes on 'Beagle'."
"I suppose so. The Gayatt is free to leave. Send the Mississippi into the testing area."
Chapter 62, the hard disk can be made smaller
The "Beagle" ship-to-air missile is one of the 50T combinations of the US Navy's ship-to-air missiles from the late 60s to the 3s.
The 3Ts are Brass Knight (long range), Beagle (medium range) and Tartar (medium range).
Later, the Tatar was replaced by the standard medium-range type, the Beagle was replaced by the standard extended-range type, and the Brass Knight was eliminated directly.
The Tatars and Brass Knights came a little later, though, and the only thing available in 1954 was the Beagle, and the only test ship was the battleship Mississippi.This old battleship built before the Washington Treaty has now changed its hull number from BB-41 to AG128, which is an anti-aircraft missile test ship.
The test of intercepting the air-to-ship missile target this time was extremely tragic. First, a single shot intercepted the incoming missile. The "Mississippi" intercepted 10 times, and the interception success rate was 0.Then it fired 2 beagles at a time to intercept a target, intercepted 6 times, and finally knocked down a target bomb the sixth time.
Whenever the target bomb passed the head of the "Mississippi" unscathed and flew into the distance and then was controlled to enter the sea to self-destruct, Robert Carney fell into deep thought.
"I think that maybe 'Beagle' is too bulky, which affects its accuracy when tracking targets." Robert Carney studied the Beagle missile with a total length of 8.2 meters and a weight of 1400 kilograms for an hour, and finally found the reason .
Well, how should I put it, the overall length of the Hongqi-2 is 4.4 meters, and the overall length of the Hongqi-4 extended range is 4.1 meters, which is exactly half of the Beagle.
Of course, the Beagle has a maximum shooting range of more than 40 kilometers and a maximum shooting height of 24000 meters, which cannot be compared with the Hongqi-4.Hongqi-4B (extended range type) has a range of only 25 kilometers and a maximum shooting height of 14000 meters.
……
The period from 1953 to 1956 was called the "Taiwan Strait Crisis Period" by the U.S. Navy. The operations of Chinese anti-ship missiles around Taiwan overturned the previous U.S. Navy's air defense theory and forced the U.S. Navy to make a technological shift.
In the past, the U.S. Navy was based on its own people, thinking that how its aircraft carrier fought, the Soviet shore-based aviation would use whatever method to attack the U.S. fleet close to the Soviet Union.
Now it seems to have changed completely.
Since 1954, American reconnaissance planes have successively discovered Soviet destroyers, frigates, and missile boats carrying anti-ship missiles in the Black Sea, the Baltic Sea, and near Murmansk, proving that such missiles have spread to the Soviet Union, China, or the entire socialism camp.
In fact, the range of the "Eagle Strike"-1 is really not as long as the Beagle's air-to-air range, but the launcher of the anti-ship missile can avoid the attack of the ship-to-air missile by penetrating at a low altitude, and then suddenly jumps up for you.
Due to the basic failure of the Beagle test to intercept the anti-ship missile target, the US Navy began the development of the Tatar missile ahead of schedule.
……
Shanghai.
Tang Hua and Liu Nai quickly figured out the development direction of Shanghai's shipbuilding industry.
The Jiangnan and Hudong-Zhonghua factories will not make a clear division of labor for the time being, and will build in parallel.
The Type 01 frigate assembled and built has been delivered, and imitation and follow-up construction is underway.Other work is to assemble Type 56, transform Keeling and Fletcher, pre-study new guided missile destroyers, and pre-study the configuration of civilian ships.
The civilian ship is considering that the U.S. Navy will not be able to be so tense forever in the future, and must enter the stage of cold confrontation.
But the biggest problem with building new destroyers is the incomplete supply chain of basic raw materials.
The first plant of Shanghai Iron and Steel that Tang Hua visited in Shanghai did not have the ability to supply marine materials.
During the period of the Republic of China, when Shanghai's shipyards were able to build new ships of more than [-] tons, they used imported steel and imported main engines.Moreover, the period when Shanghai Shipyard was able to build a large number of new ships during the Republic of China was very short.Shanghai Iron and Steel No. [-] Plant and Shanghai Iron and Steel No. [-] Plant are local steel mills that supply raw materials for civil steel products used by Shanghai enterprises. Neither of these two mills has wide-plate rolling mills for shipbuilding.
Coupled with the fact that there are many enterprises in Shanghai and the demand for steel products is huge, it is not easy to change Shanghai Steel No. [-] Plant or Shanghai Steel No. [-] Plant into a supplier of the shipbuilding industry.Even after Shanghai No. [-] Iron and Steel Plant completes the conversion of the converter, the increased production will be absorbed by the rapidly expanding steel consumption of Shanghai enterprises.
Therefore, we had to wait for WISCO to start production in 1955.
……
The matter in the shipbuilding industry was over, and Liu Nai left for Shenyang. It was time to issue the development plan for the Navy's new generation of ship-borne anti-aircraft guns.
Firearms is his old profession, and he can personally intervene in the work of the Mechanical Engineering Department.
By the second half of 1954, the national weapons industry had been adjusted and divided into four bases: Dalian, Shenyang, Taiyuan, and Chongqing.
In terms of artillery, Dalian is responsible for high-pressure artillery such as tank guns, cannons, and large and medium-caliber naval guns;
Shenyang is in charge of small-caliber automatic guns (Shen Fei's machine guns were imitated here), of course, including 37 and 25mm naval guns;
Taiyuan mainly attacked howitzers and rocket launchers of various calibers;
Chongqing focuses on low-bore pressure guns such as mortars and recoilless guns.
Firearms and 40mm rocket launchers can all be produced by the four weapon industrial bases, but there are some special emphasis in normal times. For example, the 7.62mm sniper rifle is now only produced in Dalian.
……
After sending Liu Nai away, Tang Hua went to Suzhou by himself. The first stop was Suzhou Magnetic Machine Factory.
In 1950, the Magnetic Machine Factory was one factory, now it is divided into three factories, and the fourth factory is being built.
Among them, the one with the highest technical content and the highest status is of course the first branch factory - the hard disk factory.
"Minister Tang, the capacity of the hard disk has reached 10 megabytes, and the personal computer can't run out of it. Therefore, our current technology research and development is mainly focused on reducing the size of the hard disk."
Huang Lida, the director of the No. [-] branch of the Magnetic Machinery Factory, was not a computer or electromechanical major. In fact, he was not a college student. He used to be a professional manager of a factory.But after staying in the first branch factory for two years, he can also clearly explain the general direction of hard disk technology.
"The 10M hard drive can't be used up at all..." Tang Hua repeated Director Huang's words, feeling a little funny.
"The world needs at most five computers." (5, IBM founder Thomas Watson Jr.)
"The 10M hard disk can't be used up at all." (1954, Huang Lida, director of the first branch of China Magnetic Machine Factory)
"The PC will never succeed. People don't need their own personal computers." (This sentence has not yet been said)
Tang Hua thinks that in more than ten years, some Bailey-style prophecies spoken by the bigwigs in the early computer industry can be sorted out and hung up in the teaching building of the School of Computer Science. On the top are photos or oil paintings of these bigwigs. The word is these God prophesied.
It means to let students understand that the speed of development of computer and information technology and the unpredictable direction of development are enough to make all traditional authorities fall to the ground.Now that you have stepped into this industry, you should read more about these bigwigs and their famous quotes, learn something from them, and avoid making mistakes of sticking to the rules in the future.
"Cough. This direction is right. The next generation and the next generation should study hard disks with small volumes," Tang Hua said, "but in the final analysis, it is still necessary to increase the amount of data stored per unit area of hard disks, so that when the size shrinks, , but the capacity remains the same.”
Huang Lida: "Yes, yes, I know. Director Li Qiang said that our next-generation computer is only this big, and the ordinary computer case in the future will only be this big, so the hard disk has to be made smaller."
Huang Lida stretched out his hands in front of his chest to compare the length, width and thickness of the case, "But I feel that a 10-megabyte hard drive can't fit into this kind of case in the past one or two years."
