    When Yang Qiu got the telegram, it was already the morning of April 26. Due to the time difference, there were still five hours before the scheduled general attack on Tashkent.  // // "Judging from the content, there is not much information, but look here we need to replenish 10,000 barrels of diesel." Yan Baohang stood in front of his desk, analyzing the new telegram intercepted yesterday: "From our  According to the information available, only T34 tanks need to use such a large amount of diesel in the Soviet army. Previous intelligence has shown that as of the end of last month, about 3,000 T34s of various models had been replenished on the front line, so it is basically certain that they are provided to the T34 tank army. Also  The last sentence, which must be set off from Orenburg before May 1, can also explain that the counterattack should be between May 1 and 3."

    "So, Lukin wants to advance in depth with the Akdem Mountain Highlands as the axis?"

    As Yue Peng flew directly from Paris to the front line, Chen Shaokuan, Zhang Xiaozhun and others began to formulate plans for Vietnam. Song Ziqing and Air Force Commander He Ning, who stayed in Beijing, took on the work of the general staff, plus Jiang Fangzhen, the presidential adviser.  , forming a temporary Presidential Military Staff Group.

    Jiang Fangzhen put down the information in his hand and shook his head: "It may not be him alone. According to the previously intercepted information, the day after the German army attacked France, Stalin successively transferred 600,000 troops from the Southwest, Moscow and Don River Military Regions to supplement Siberia and Kazakhstan.  Front. There are about 10 divisions departing from Baku to supplement the Karakalpaks Front, and 14 divisions to supplement the Caucasus Front. Judging from the order of troop deployment, Zhukov's Siberian Front was the first to be supplemented, but his side has only just melted the snow.  Floods and mudslides occur frequently, making it completely unsuitable for an offensive. Therefore, we suspect that he is very likely to go south from Petropavlovsk to participate in the counterattack. If he really joins forces with Lukin, he will be able to assemble eighty divisions and five aviation  division and three tank corps. With such a large force, a single gap in the Akdem Mountain Highlands is not enough, because the Ishim and Hidelt rivers are in front of it, and the geography cannot accommodate so many troops. What's more, they  We also know that the troops¡¯ mobility is not as good as ours, so there should be a breakthrough.¡±

    "Xu Shuzheng and Long Yun also think so. Preliminary research should have four possible attack points. From north to south, they are Ekibastuz, Akdem Mountain Highlands, Shakhtinsk and Rhezikaz.  Gan." Song Ziqing continued: "After research, we feel that Shakhtinsk and Rhezikazgan are the most likely. The front is the gateway to Karaganda. The troops behind are the weakest, and there is still a gap between it and Kyzylorda.  There is a fairly large open area, connected only by a dirt road. Liu Mingzhao¡¯s Uletau Mountain Defense Line is said to be a mountain, but it is actually a hill with a height of three to five hundred meters, which is also more suitable for the movement of armored troops.¡±

    With the exception of the clear highlands of Mount Akdem, the probability of choosing one of the three is really slim.  After reading it, Yang Qiu set his sights on Chelyabinsk.  At the end of the day, Lukin and Zhukov are alive and kicking.  It was entirely because several key supply routes had not been destroyed.  Before, there was nothing we could do because of the severe cold in winter, but now is it mature?  So he turned around and asked: "He Ning, can't your Air Force blow up a few supply channels?"

    He Ning is very short, standing in front of Yang Qiu like a middle school student.  But he is one of the main officers who started out in the Air Force. He has participated in all reforms and tactical formulations since the founding of the army, and took over as the commander-in-chief of the Air Force five years ago.  He is a rare air force expert.  But this time he shook his head: "We have a plan, but it will take at least twenty days to prepare."

    "Why?" Yang Qiu asked.

    He Ning stood up and walked to the map: "At present, we have built five large airports in Karaganda and Pavlodar, which are capable of taking off and landing large aircraft such as H-7 aircraft. The problem lies in the distance. With Karaganda as the  The starting point is 620 kilometers away from Petropavlovsk and 980 kilometers away from Chelyabinsk. Orenburg is 1,180 kilometers away. These three points are the distribution points for supplies throughout Siberia and East Kazakhstan. In order to completely cut off Lukin and Zhukov  supply. We need to knock out these three places. But our army's currently largest H-7 has a combat radius of only 400 kilometers when fully loaded with 10 tons, 5 tons is 700 kilometers, and 3 tons is 1,000 kilometers. Take Chelyabinsk as an example.  , there are complete heavy industry facilities here, and the city is relatively large. There are two aviation divisions around the city, equipped with 700 aircraft of various types, and more than 800 anti-aircraft artillery pieces of various types. Ufa and Yekaterinaburg in the rear are also  There are three to four aviation divisions for support. At the end of last year, the Soviet army also deployed two rus-1 radars here. Although this radar has poor performance and can only detect high-altitude targets 35 kilometers away, it can basically be used with air defense listeners.  Guaranteeing an early warning of 40 to 50 kilometers. In addition, the average thickness of the exterior walls of Soviet buildings is one meter, and some are two meters thick. A 250-kilogram bomb is required to ensure destruction. So according to our calculations, if the distance cannot be shortened to 700 kilometers  , it will take at least 3,500 sorties to destroy it, plus about 1,500 sorties are needed in Petropavlovsk, a total of 5,000 sorties are needed to ensure destruction.

    There are also escorts. Currently, the only two-headed dragons and thunderbolts that can remotely escort and seize air supremacy. The former lacks air combat capabilities, and the latter even with three auxiliary fuel tanks.??It's only 2,300 kilometers.  According to the calculation that the maximum combat radius is one-third of the maximum range, it can satisfy Petropavlovsk, but it must return after a circle around Chelyabinsk, and it cannot get entangled with enemy aircraft in the middle.  The latest J-8 is currently available for use by only two brigades. Based on the number of bombing sorties, I need at least 5 brigades to ensure continuous escort.

    Based on the above calculations, each aircraft needs at least 11 tons of ammunition and fuel (3 bombs, 7 fuel, and 1 remaining) and other supplies for each dispatch. This is 55,000 tons, not including accessories prepared for damaged bombers.  Moreover, once the bombing starts, it cannot be stopped. In order to prevent the enemy from moving, it must continue with high intensity for ten days to half a month, so there cannot be any interruption in material supply.  This amount cannot be achieved by relying on trucks. The train line to Karaganda will not open to traffic for another twenty days, soit's not that we can't dispatch, but that we don't have enough supplies.  If it is just a small-scale bombing, I suggest that it is better to give up or let the H-5 carry out short-range tactical bombing on the communication lines. Otherwise, it will only alert the enemy and force the Soviet Union to move the machinery and equipment further away to Stalingrad and Ufa.  "

    He Ning¡¯s words were like a drum at dusk.  Yang Qiu's dream of carrying out strategic bombing was awakened. Look at Song Ziqing's self-deprecating smile: "It seems that you can't even think about becoming fat after one bite."

    Song Ziqing said: "President, a 20-day delay is not a big problem, and Baili and I do not recommend telling the front line of intelligence. Whether it is Zhukov or Lu Jin, if they hit an ambush during the first counterattack, they will definitely suspect that the password has been leaked."  The problem is, if the Soviet Union changes to a new code, it will be detrimental to the future. And our current difficulty is mainly in Tashkent, because a large number of troops are restrained. Therefore, when Long Yun deployed the defense line, he had to go along Kyzylorda to Pavlov  Dar's straight line planted troops one by one like radishes. This destroyed his mobile warfare ability. He is now aware of this problem and is discussing a solution with Liu Mingzhao. Xu Shuzheng has also temporarily given up attacking Omu.  Sk, the Siberian 21st Army has been transferred to Pavlodar, the reserve 26th Army and the North Korean Third Army have also gone up, so that we have 7 armies north of the Aral Sea, and the five divisions of the Kazakh Independence Army will also be there.  Heading west in five days, as long as the direction can be determined. The Soviet movement only needs to be delayed for a month, and after Tashkent is resolved, it can still be counter-encircled."

    His words make sense. In another world, the Soviet code has never been deciphered.  Not only because of the strong confidentiality, but also because of frequent changes.  Now that I have such a good opportunity, if it is exposed too early and it comes at four o'clock, I will completely change the password structure.  On the contrary, it is not conducive to the subsequent war.  So Yang Qiu thought about it and decided to follow his method and not tell the front line: "Go back immediately and remind Xu Shuzheng and Long Yun in the name of the General Staff to be careful about counterattacks. The rest suppress it! Contact Yue Peng again.  , There is no need to return to Beijing for the time being. Supervise the Tashkent troops on the spot and be sure to hurry up."

    At the same time Yang Qiu made the decision to suppress the telegram.  Troops with different numbers once again gathered in the fortification area of ????Zhangebazagang, which had been troubled for a month.  During the continuous bombardment of the two hammer heavy train guns, the entire fortification area had been shattered. If it were not for the fortress group behind it, it would have been broken through by the armored group long ago.  "Damn it, if you can't break it open this time, I'll just lead my troops and rush in!" Zhu Dakui, the commander of the 137th Division of the 29th Army, threw his helmet to the ground and climbed onto the roof of the Type 35 Hunter-Destroyer Tank next to him.  , looking into the distance and cursing.

    Around the tank, tens of thousands of soldiers were waiting eagerly like him, waiting for the order to attack.

    When various troops arrived one after another, the field airport was already busy.  The ground crew hung three long, dark bombs under the bodies of three specially modified ghost car dive bombers.  The new bomb attracted many officers. Even Yue Peng, who had just returned from France, squatted down and took a closer look: "Is this an earth-penetrating bomb modified with a gun barrel?"

    "Yes, we call it bomb No. 20."

    "Huh? Why this name?" Dai Jintang grabbed Qiu Heng and Jia Xiaohou, who had personally delivered the bomb, and asked.  After the war began, the former had handed over the position of general manager of 3010 to Leng Jie and returned to the familiar equipment department.  Compared with the taciturn Qiu Heng, Jia Xiaohou was more confident about the bomb and introduced it immediately.

    It turns out that after Yang Qiu proposed using the gun barrel to replace the ground-penetrating bomb, Qiu Heng immediately went to Norinco, the company with the strongest special bomb manufacturing capabilities.  When Jia Xiaohou learned that there was an urgent need on the front line, he immediately stopped all work in the design department and led hundreds of technicians to conduct intensive research.  In just five days, the preliminary design was completed.  Then it took two days to cut the three captured B4 gun barrels into six sections. After mixing a large amount of tungsten powder with the remaining material and using special hardening technology, three cone warheads were cast and filled in the barrel.  TNT explosives, coupled with tail stabilizing fins, and finally installed delay fuses for naval armor-piercing bombs, thus completing six 1,200 kg ground-penetrating bombs.

    However, no one dared to take this to the front line. In order to save time, Qiu Heng directly selected the Hushan Fortress in Jiuliancheng on the Yalu River for experiment.  This person was bombarded back thenThe fortress that Yan Youbing burned down has been repaired, but it was included in the second line due to North Korean control.  After the Air Force agreed to share technology, the Navy gritted its teeth and contributed the fortress.  But as soon as the fortress was selected, there was another problem with the plane.  Because the maximum bomb load of the ghost car dive bombers is only 1 ton, the Air Force removed the armor of the two experimental ghost cars overnight and filled them with the best high-grade 110 aviation gasoline in the country to meet the requirements.  In the end, Qiu Heng directly transferred the remaining armor materials from the Qingdao Shipyard to build the Shandong-class battleships, and laid 300 mm thick Krupp surface carburized armor on the top of the fortress. The engineers also reinforced it as quickly as possible to imitate the Tashkent Fortress as much as possible.  .  After such operations, the actual protection thickness of the fortress has reached 500 mm.  At that time, everyone thought it was too thick and would definitely not be able to be broken open.  Unexpectedly, the first ground-penetrating bomb successfully punched a big hole in the armor.  Although it did not penetrate, it gave everyone a lot of confidence. Finally, after more than a dozen consecutive experiments, on the 20th day, the Navy test pilot dived from an altitude of 4,000 meters at a speed of more than 850 kilometers per hour and at an angle of more than 80 degrees.  , not only did the ground-penetrating bomb hit the fortress vertically and penetrate the armor, it also continuously penetrated two layers of 3-meter-thick reinforced concrete boards and exploded internally.

    Finally, in order to commemorate this little 20-day legend, everyone simply named the bomb No. 20 bomb.

    After the prototype was finalized, Jia Xiaohou led the technical team to make 12 more in one go and sent them to the front line first. Because of the rush, they didn¡¯t even paint them, so they looked like dark iron pipes with arrows.  "Let's go to the sky and take a look. I want to see how powerful this No. 20 bomb is." Dai Jintang, who was aroused by his curiosity, was the first to be unable to sit still and took several officers to the battlefield and boarded the observation machine.

    Ten minutes later, three ghost car dive bombers with overloaded loads staggered into the void like old pond geese

    Note: Soviet radar technology appeared not too late. Historically, the two radars rus-1 and rus-2 were equipped with the Soviet homeland defense air force in 1939
