PS: I went to Changsha today to drink a friend's wedding wine, so I delayed the update. Please forgive me for any inconvenience caused to a respected book friend.

Tomorrow I will make up all the chapters I owe today!

The outbreak of the war in Afghanistan ushered in an unprecedentedly relaxed international environment for China.

The US Government has long judged that the Soviet Union may launch armed aggression against Afghanistan, and it is also actively making various countermeasures and arrangements.

However, the sudden hijacking of the U.S. Embassy in Iran by radical armed Iranian students suddenly turned the attention of the entire American society to Iran.

And it was at this time that the USSR got its hands dirty.

The Soviet Red Army, with its overwhelming superiority in forces and modern weapons, invaded Afghanistan in a surprise attack.

On December 24~26, 1979, the Soviet army dispatched 280 large transport planes to airlift more than 5,000 officers and soldiers and a large number of weapons and equipment to Kabul International Airport and Baghlan Air Base.

At 7:30 p.m. on the evening of 27 July, the Soviet troops stationed in Kabul occupied the Afghan summit organs, the Ministry of National Defense, and the radio station, killed Amin, smashed the resistance of the Afghan government army, put Karmal on the throne, and declared that a coup d'état had taken place in Afghanistan.

On the 28th, the six divisions of the Soviet Red Army assembled on the Afghan border launched a pincer offensive against Afghanistan in the east and west.

The three divisions of the Eastern Route moved south along the Termez-Mazar-i-Sharif road;

Three divisions of the Western Route moved south along the Kushka-Herat road.

On January 2, 1980, the Soviet Union's Eastern and Western Armies met in Kandahar. Within a week, Soviet forces had largely completed the occupation of Afghanistan's major cities and major communication routes, and had taken control of key border areas between Afghanistan and Pakistan and between Afghanistan and Iran.

At this stage, the Soviet Red Army dispatched a total of 7 divisions and 80,000 people, and the Afghan government army under Amin's control, 1 corps and 13 divisions, with a total of 100,000 people, basically did not resist the invasion of the Soviet Red Army, and most of them surrendered and surrendered to the Soviet-supported Karmal regime.

The situation in Afghanistan has deteriorated dramatically. Coupled with the fact that the hostage crisis in Iran has not been properly resolved for a long time, President Carter really has no choice but to turn his attention to the close friends of the American people for help. Chinese.

In line with the principle of international political relations, the superficial things that the Chinese government should do are, of course, more or less pretentious.

Therefore, the Commission of Science, Technology and Industry for National Defense acted in accordance with the spirit of the Central Committee. Command all military industrial enterprises to replace all Type 56 gun families and light and heavy artillery guns in the whole army, including a large number of supporting ammunition in stock. With a little renovation, it can be handed over to Afghan guerrillas through the Wakhan corridor on the Tashkurgan border in southern Xinjiang.

According to the transaction price of the international arms war, the US Government will pay for it at a 6% discount.

The U.S. administration now doesn't care about the price at all, it just wants the Afghan resistance groups to have a steady supply of weapons and ammunition to fight the Soviet invaders.

For international political reasons. The US administration is reluctant to openly provide military aid to Afghanistan, fearing that it will further worsen the antagonistic relations between the United States and the Soviet Union and trigger a world war.

Based on this idea, the United States and Britain, on the one hand, turned over all the Soviet-made weapons in the stocks of European countries, and on the other hand, entrusted the Chinese government to manufacture Soviet-made weapons and ammunition in large quantities.

Our light and heavy conventional weapons. Basically, they are all derived from Soviet technology, and guns, ammunition, and shells can be used universally, which is extremely convenient for the Afghan guerrillas to seize Soviet equipment and ammunition from the battlefield, replenish them on the spot, and reduce logistics supply.

Since the Americans are paying the bill, the major arsenals are of course refurbishing and manufacturing the original standard weapons and equipment of the Chinese People's Liberation Army at full capacity.

The production line is ready-made, the raw materials are also ready-made, and the workers in the factory are even more skilled and experienced than before.

War has always been the best catalyst for speeding up industrial development and enhancing the content of science and technology.

The war in Afghanistan broke out as scheduled, and the Iranian hostage crisis also continued, so the Iran-Iraq war is not far off.

In the face of such a favorable international environment, and in addition to the fact that the US Government is waving a check and crying and begging for Soviet-made weapons to support Afghanistan, Yang Weiping naturally instructed China's military enterprises to produce arms at full capacity.

At the political level, the No. 1 chief personally worried about it, and Yang Weiping once again devoted his energy to paying close attention to scientific research.

A large number of basic industrial technologies exchanged for GB-HD79-A standards, combined with China's original industrial base, have made China's basic processing technology capabilities qualitatively transformed. The most obvious of these are material applications and precision machine tools.

The fifth-generation CNC machine tool controlled by microcomputer has been mass-produced.

In terms of machining accuracy, ordinary CNC machine tools have been increased from the original 20 microns to 10 microns. The precision machining center has been increased from 10 microns to 3~5 microns. The pre-developed ultra-precision machine tool prototype has reached a breakthrough of 1~1.5 microns in machining accuracy.

The improvement of machining accuracy not only lies in the application of ball wire auxiliary rods, hydrostatic guide rails, linear rolling guide rails, magnetic levitation guide rails and other components, improves the control accuracy of numerical control programs, and applies high-resolution position detection devices, but also uses a variety of error compensation technologies such as screw pitch error compensation, tool error compensation, thermal deformation error compensation, and spatial error comprehensive compensation.

The five-redundancy program has been popularized in ordinary CNC machine tools, the seven-redundancy program has been maturely applied in the precision machining center, and the nine-redundancy program has been repeatedly verified and improved in the ultra-precision pre-research prototype.

Compound of the Commission of Science, Technology and Industry for National Defense.

After reading the annual summary report of Huaxia First Precision Industry Group last year, Yang Weiping was still quite satisfied.

Although there is still a little gap in ultra-precision machining compared with the United States and the Federal Republic of Germany, the overall technology of Huaxia precision machine tool manufacturing industry has been improved, which has made the finishing and precision machining capabilities of China's basic industries improve qualitatively.

As soon as he put down the document in his hand on the desk, he heard a soft knock on the office door from the outside.

"Please come in!" he said, picking up the panda cigarette on the table, striking a match, lighting one, and taking a deep breath.

Jiang Tiegang pushed the door open from the outside, and behind him were two middle-aged and elderly officers in Type 81 civilian military uniforms.

I saw that one of them was Academician Lu Xiaopeng. Yang Weiping immediately stood up, put the freshly lit cigarette in the ashtray, and walked out from behind the desk to greet him.

"Lu Lao. When did you arrive? Why didn't you call in advance, I'll send a car to pick you up!" Yang Weiping enthusiastically stretched out his hands to shake Academician Lu's hands, and beckoned the two guests to sit down on the sofa.

"Director Yang, you have a lot of opportunities. For such a trivial matter, I won't trouble you. Academician Lu thanked him quite sincerely, and then pointed to the nearly fifty-year-old civilian colonel who came with him. introduced: "Director Yang, this is Yongzheng Qiu Yonggong, the chief engineer in charge of production. ”

Hearing this, this is Yong Zhengqiu, the chief designer of the previous strong five M, Yang Weiping just sat down and immediately stood up.

"Hello chief!" Yongzheng Qiu held his head high and saluted Yang Weiping with a standard military salute.

Yang Weiping raised his arms very seriously and returned a military salute, then stretched out his hands and held Yongzhengqiu's hands together, shaking his hands. "Hard work, Chief Engineer Yong!"

"Serve the country, you should be!" Yong Zhengqiu said sincerely.

"Director Yang, I came to the capital this time to hand over the task to you. Lu Xiaopeng's thin face was full of joy. He solemnly said: "After a three-month sea trial, our Qiang-5 carrier-based aircraft can be finalized and mass-produced! From then on, the Chinese People's Liberation Army Navy has one more long-sky sword in the field of defending the motherland!"

"Lu Lao, I thank you on behalf of the navy! On behalf of the party and the country, I thank you!" Yang Weiping warmly shook hands with Lu Xiaopeng again, and then solemnly saluted Lu Xiaopeng.

"Loyal to the country, duty-bound!" Lu Xiaopeng solemnly saluted in return.

"This sea trial went well, right?" Yang Weiping asked with concern after inviting Lu Xiaopeng and Yong Zhengqiu to sit down.

"It went very well!" Lu Xiaopeng nodded affirmatively and replied: "We strictly follow the safety rules for the sea trials of carrier-based aircraft and aircraft carriers provided by you, without missing any details, and no safety accidents have occurred!"

Yang Weiping let out a long breath after hearing this, and said comfortingly: "That's good, that's good." How is production progressing so far?"

"According to the standards formulated by the Commission of Science, Technology and Industry for National Defense, the Qiang-5 carrier-based type is divided into two types. Lu Xiaopeng replied seriously: "The installation of two WP6A turbojet engines is finalized as the strong five B1 type, and two are installed."

The WS6-H1-1042 military small-thrust turbofan engine is finalized as the strong five B2 type.

The Qiang-5 B1 and B2, after they are both equipped with HD79-A avionics systems, are no longer simply attack aircraft specifically responsible for ground attack, and can completely perform a variety of combat missions against the air and the ground! The Qiang-5 B1 has a maximum flight speed of Mach 1.5, a cruising speed of Mach 0.85, a combat radius of 620 kilometers, and a ceiling of 17,500 meters, while the Qiang-5 B2 has a maximum flight speed of Mach 1.8 and a cruising speed of Mach 0.9, a combat radius of 650 kilometers, and an altitude of 18,000 meters. ”

Hearing these two sets of figures reported by Lu Xiaopeng, Yang Weiping realized that these two carrier-based aircraft can no longer be regarded as strong five, but have become another second-generation semi-light multi-role fighter close to the third-generation fighter.

If the Jian-15 Haidongqing has not been established for research now, these two light fighters, which are infinitely close to the third-generation fighters, can still be used.

But now that there are better options, the strong five B1 and B2 are a bit at a loss for how to position.

In the first place, it can only be regarded as a professional export model, and it can also be used for the training of carrier-based aircraft pilots first.

The Navy's F14 pilots have been using carrier-based aircraft as land-based aircraft. Because there is no aircraft carrier platform for the F14A to take off and land, these pilots cannot be called carrier-based aircraft pilots at all.

After thinking about it, Yang Weiping still decided to produce a batch of them, on the one hand, they can be exported to earn foreign exchange, and on the other hand, they should be medium-level carrier-based training aircraft. (To be continued.) )
