Back to the Republic of China to be a editor

Near Shanghai, the factory in Kunshan is using the laser ablation machine developed by the industrial laser group to engrave the words T53 and the logo of the Electronic Information Industry Bureau on the cabinet of the T53 computer.

In Shanghai, Zhou Xuan teased cats with a laser pointer.In Moscow, Lev Landau was holding the laser pointer that Tang Hua gave him—and was also teasing the cat.

And tease three cats at once.

……

Tang Hua is not only concerned about what Changchun Optoelectronics is tinkering with now, but also with Changchun Optical Instrument Factory next door.

"Minister Tang, we have mass-produced Su-1 in January! The quality is comparable to that of the Soviet Union. This is the conclusion of the Soviet experts' appraisal!"

Su Liu is a 6X30 telescope made in the Soviet Union, 6 is the multiple, and 30 is the diameter of the telescope's objective lens.

Why is Su Liu not Cai Liu or Cai Ba, because Changchun Optical Instrument Factory was built with the assistance of Kazan Optical Instrument Factory.

But in this era, Zeiss was first separated from East and West Germany and then poached by the Soviet Union for a round. Therefore, the strength of several major optical instrument manufacturers in Kazan, Minsk, and Leningrad at this time is no less than that of Zeiss.

Although there was a lot of noise on the phone, the excitement and pride of Chang Guang's factory director were beyond words.

Although Su Liu seems to be a "high-end product" - an ordinary military telescope for low-level Soviet officers, it is quite a test of Changguang.There are more than a dozen lenses and prisms inside a telescope, and the material, grinding process, and assembly accuracy of each lens/prism must not be sloppy.By making Su Liu, Changguang has taken the first step, and it is the first step with a high starting point.

"Starting from scratch is a great first step, but Suliu is only the first step in the long march," Tang Hua said, "Suliu will continue to maintain mass production, train the technician team, and improve the craftsmanship of the whole factory. In the next five years The development plan has been sent to you, and you have no chance to slack off during the First Five-Year Plan."

The glass formula needs to be expanded, and Su Liu's barium optical glass will be smelted, and there will be more than a dozen formulas of optical glass, which will be tested furnace by furnace.

The mirror grinding process needs to be improved, at least one order of magnitude higher than that of Su Liu, and eventually two orders of magnitude.

The assembly accuracy of parts also needs to be improved by orders of magnitude.

"We understand. This year, while we are mass-producing Su-[-], we must step up the localization of the 'four mirrors'."

The four mirrors are Suba military binoculars, the Caiba gun sight of the Bayi-type sniper rifle, the lens group of the infrared laser receiving system of the laser-guided bomb, and the lens group of the infrared night vision device.

Open four research and development lines at once, but this is still far away.

Su Ba is a commodity in the hands of scouts and artillery officers. In fact, the army cannot do without artillery mirrors—a periscope with dual objective lenses and high-power ranging functions.A range finder is also needed-well, the laser range finder is here, but the laser range finder also has a lens group; a sight for a direct-pointing cannon; a sight for a tank gun; the anti-tank missile system that was put into production half a year ago is more expensive, There are two mirrors with high/low magnification.In a few years, it will be time to make machine gun sights on fighter jets. I have no time to take care of these, so I can only import them reluctantly.

In the future, laser-guided and infrared detection/guidance weapon systems will continue to appear, and each type of weapon system has optical components.In addition to military products, there are also civilian products-in the future, China will always manufacture domestic cameras, movie cameras, and TV cameras.

Now Tang Hua has to look forward to the ruined factory left over from the Republic of China in Kunming to quickly integrate and renovate with the help of Soviet experts, tinkering until it can produce things.If possible, Chongqing and Shanghai may also be built.After the transformation of the factory is completed, some low-end optical products can be handed over to Kunming Optical Instrument Factory, and Changguang specializes in high-end.

South Korea, Busan.

"Senseless offensive and defensive warfare. Neither our side nor the North Korean military achieved any meaningful results."

Van Fleet frowned, and the battle report in front of him was dripping with blood—although most of it was the blood of South Koreans, it also made him very unhappy.

"We have to create a channel of dialogue with China," UN chief Clark agreed with Van Vleet's assertion that the battle is pointless, "that represents an official dialogue that does not involve North Koreans or South Koreans."

Because both China and the Korean peninsula were using the lunar calendar at this time, the battle on the Eastern Front was later called the "Spring Festival Offensive" of the People's Army.

It was the two regiments of the 5th Division and the 13th Division of the 15th Army Corps of the Korean People's Army that launched the attack.

The Korean People's Army pointed the spearhead of the offensive at the area near the coastline on the eastern front, which is Longdai-ri east of Inje County.To the north of this mountain village, the South Korean Capital Division occupied 6 hilltops and stationed two battalions to guard them. On the mountain south of Longdairi, the Capital Division deployed two regiments, with a typical front-light and rear-heavy configuration.

The People's Army wanted to capture the hilltop where the South Korean Army was stationed in the north of Longdae-ri, exposing Longdae-ri to the firepower of the People's Army, and the road where this existence was located could not be used by the United Nations Army.After the road was cut off, the two northernmost towns controlled by the United Nations Army on the east coast of North Korea—Goseong County and Sokcho City—appeared very abrupt. They either withdrew their troops under the cover of warships, or had to endure endless attacks by the Korean People’s Army. Shelling harassment.

This is actually the purpose of Kim Il Sung's battle, and he wants to get back one or two goals in the final battle.Goseong County and Sokcho City are all north of the [-]th parallel, and the area of ​​Yongdae-ri is actually the same.The western front was completely cut to the south of the [-]th parallel by the Volunteers. This is of course very good, but if the eastern front can take back a little bit of the territory north of the [-]th parallel that the United Nations army crossed the border, wouldn't it be more face-saving?

February 1953, 2, which is New Year's Eve.The two main regiments of the 6th Division of the 5th Corps of the People's Army lurked in the snow for a day, and the combat troops approached and hid less than 13 meters from the hilltop positions of the South Korean Army. On the evening of February 200, after a burst of "Katyusha" and heavy artillery fire, two regiments of the People's Army suddenly launched an attack on the two highlands 2 and 6 occupied by the South Korean Army. It was still getting dark quickly in February. The Korean People’s Army and the South Korean Army fought from dusk until late at night, from 605 meters to 660 meters. Finally, the two sides entered into bayonet hand-to-hand combat. In the early morning of February 2, the two battalions of the Capital Division finally Being repelled, some retreated to the foot of the mountain and some retreated to the reverse slope tunnel. The Korean People's Army occupied the surface positions of 200 and 2.

Highlands 605 and 660 are the two highest among the six hills occupied by the South Korean Army. During the daytime on February 6, the 2th Division began to deal with the South Korean Army hidden in the tunnel on the reverse slope, and the 7th Division of the People's Army dispatched a regiment. Taking advantage of the opportunity to attack the other 13 hills in this area, they even pulled the tank regiment to the vicinity of the battlefield and used tank guns as fire support platforms.

At the same time, the South Korean capital division's counterattack to regain the 605 and 660 heights also started during the day on February 2.

The 13th Division of the People's Army was under the counterattack of the anti-slope tunnel in South Korea, the upward attack of the Capital Division, heavy artillery bombardment and aircraft bombardment (the mountains in this area are too high, and the 605 and 660 highlands protrude from the front line, and the Red Flag-1 and Hongqi-2 can't control), held the position during the day, and the 15th Division also won two of the four secondary highlands.

On the night of February 2, the Capital Division came up with another regiment, plus combat engineers, to carry out a night attack on the 7 Heights.The battle was like the night of February 660th, except that the offensive and defensive sides adjusted each.From the night of February 2th to the early morning of February 7th, the exhausted People's Army pushed the South Korean Army out of its position again.After fighting day and night, two regiments of the South Korean Capital Division were disabled, as were two regiments of the 2th Division of the People's Army.However, when the South Korean army failed to attack and retreated, some soldiers did not go down the mountain directly, but also got into the reverse slope tunnel, which provided convenient conditions for the South Korean army to counterattack later.

During the daytime on February 2th, I realized that the Korean People's Army was fighting a bit big. The 8th Army of the Volunteer Army in Yangkou County sent two 24mm rocket artillery battalions, and the 108th Artillery Division sent two heavy artillery regiments to participate in the battle. With the support of the army, the daytime defensive battle on February 4 was also won, but the price paid was indeed not small, and the casualties were particularly serious on the 2 highland. The last regiment of the 8th division as a reserve team had sent a battalion to support the scene.

2月8日下午，人民军5军团电报发往志司，请求志司下令让附近的24军72师加入战场，或者至少要派一部分部队对5军团予以援助。

Zhisi asked Beijing for instructions. The chairman thought for a long time and ordered the 72nd Division to dispatch two regiments to move eastward, planning to take over part of the People's Army's positions on February 2.

But in the daytime of February 2, this lengthy offensive on the Eastern Front ushered in a second turning point.

In the past two days, the 7th Meibu Division on duty on the Eastern Front did not provide any actual support, but was actually mobilizing heavy artillery. On the morning of February 2, two battalions of 9mm howitzers were finally pulled by heavy tractors from the south bank of the Han River to the Eastern Front.At 203 o'clock in the morning that day, the 10mm howitzers were deployed and fired the first round of salvo.

美军榴弹炮第一轮覆盖的是人民军605高地。虽然距离有400多米，在660高地的观察员仍然感觉大地在晃动。203毫米榴弹炮的炮击持续了半个小时，660高地的表面阵地变得更加残破。

After the bombardment ended, U.S. A-26 bombers flew over the position, and eight planes dropped a string of bombs on Height 8.When approaching the ground, the bombs opened their parachutes one after another to slow down.Then, the entire theater—including all the hills occupied by the People's Army and the South Korean Army—felt strong flashes of light and waves of air rushing toward us.

Chapter 20, Secret Talks in Hong Kong

Because of the People's Army's Spring Festival offensive, Tang Hua started working on the second day of the Lunar New Year.

The staff officers and guards who came to the door handed the telegram notification to Tang Hua, without describing the specifics, only saying that they should immediately find a place where they need a phone call to discuss matters.

"Is it the Shanghai Garrison District or the East China Bureau?" Tang Hua asked.

"Go to the East China Bureau."

The Confidential Section of the East China Bureau is located next to the People's Committee on Nanjing Road, Shanghai.

The jeep drove on the busiest road in Shanghai, and it was during the Spring Festival. The streets were bustling with crowds. Karaoke halls, cinemas, restaurants, bars, teahouses, and bookstores seemed to be open except for the barber shop.On the side of the road and under the signboards, apart from the crowds shopping, one or two sentries with guns standing guard or patrolling soldiers of the People's Liberation Army can be seen from time to time.

Standing guard here is the original Mortar Company of the Guard Brigade of the East China Military Region, which was later renamed the Eighth Company of the Second Battalion of the First Internal Guard Regiment of the Shanghai Public Security Corps.

It is known as "Haobalian on Nanjing Road".Tang Hua originally wanted to take a good look at the military appearance of the Eighth Company, but the car had already stopped at the building of the confidential department.Speaking of which, the eighth company's resident is located on Nanjing Road, probably because there is an important institution here.

"Hello? Can you hear me? I'm Tang Hua."

"I can hear you. I'm Wang Ganchang. I just returned to Beijing yesterday." Amidst the rustling of the long-distance phone, Wang Ganchang spoke.

"It's been a lot of hard work in North Korea for so many months."

"Minister Tang, I came back mainly to report on the situation on the battlefield. During the Eastern Front campaign launched by the Korean People's Army from February 2th to 6th, the US military used cloud bombs."

……

During the daytime on February 2, in order to cooperate with the South Korean army to counterattack and recapture the 9 and 605 highlands, the U.S. military sent two waves of planes and carried out two cloud bomb attacks.

These two cloud bomb attacks almost achieved the best results: the position of the People's Army was just captured from the South Korean Army, and only surface trenches and some shallow tunnels for Tibetan soldiers were occupied. The tunnel fortifications on the reverse slope have not yet been occupied by the People's Army.

At Heights 605, 8 A-26 attack aircraft (with ammunition capacity close to that of medium-range bombers) dropped 48 500kg cloud bombs with a total ammunition weight of 24 tons.The cloud bomb dropped by the drogue parachute detonated and released once, and then detonated and ignited the second time. The flash, shock wave and subsequent rising mushroom cloud shocked the audience just like the sixth battle in the Hanjiang North Plain last year.
