This problem is not very difficult to solve either.

With a slight turn of his mind, Liu Yun thought of a countermeasure, "With the current aircraft production capacity in western Sichuan, it can produce 120 aircraft per month, well, some have been stored over the years, and it is estimated that in the next month or two, more than 400 fighters can be produced."

"Only the transportation is troublesome, although the West Sichuan Railway is connected with the Xi'an Railway, but it has to go around most of China to reach Nanjing."

"One is to ship goods from the West Sichuan Arsenal, through Fucheng, Guangyuan, Xi'an, Luoyang, and then directly to Nanjing Pukou (there is no Yangtze River Railway Bridge, Pukou is the end of the Jiangbei Railway Line), and the second is to transport from Xi'an to Wuhan, and then transfer to water transport to Nanjing."

"As for the problem of pilots, it is not very difficult either".

"You can directly recruit volunteers in the Soviet Union or the United States, and I believe that as long as you can come up with gold and silver, you can have as much as you want, not to mention that Mrs. Song is negotiating in the United States, and if she really wants to do this, I believe that the US government should not be too embarrassed."

But when someone mentioned the Soviet Union, Lao Chiang's heart moved.

He asked with some eagerness, "Yicheng, how can you be sure that the Soviet Union will agree to send a volunteer air force?" In the past few days, Soviet Ambassador Bogmolov has frequently proposed to meet with me in private. ”

Commander Liu smiled slightly, "The fact that the Japanese devils dared to brazenly invade China has a direct relationship with the fact that the Germans secretly signed the "Anti-Soviet Agreement" in November last year."

"But everything has its advantages, and there are disadvantages."

"This agreement also caused the Soviets to be extremely wary of the Japanese devils, and they absolutely did not want to see China compromise with Japan."

Needless to say, "The enemy of my enemy is my friend."

What's more, once China falls, the Soviet Union will face tens of millions of Japanese-Chinese coalition troops, not to mention that the Soviet Union's territory in the Far East is lost, so if you don't want to be surrounded by Japan and Germany, aiding China is the only choice.

As for the question of tanks, the difficulty is not too great.

The Germans had already sent the manufacturing technology of the I. and II tanks to the Nanjing government, and the Jinling Arsenal and the Hanyang Arsenal were stepping up manufacturing and putting 500 vehicles into the Songhu battlefield.

The only regret is that there are no professionals available in the huge Huaxia.

Liu Yun suggested borrowing generals from the Soviet Union, such as Comrade Zhukov, a "tank professional".

Zhukov, whose full name is "Georgy Konstantinovich Zhukov", was awarded the second Marshal of the Soviet Union in January 1943 after Comrade Stalin.

At the beginning of 1937, due to the Great Purge of the Soviet Union, there were some signs of this guy being raised and secretly surrendered, and it was a very delicate time at present, if Yan'an wanted to help and send Huaxia to command the tank troops to fight against the evil Japanese devils, it was the most suitable candidate.

Letting a Soviet Red Army command the army in China is unreliable no matter how you look at it.

Wouldn't this make all the military secrets of China exposed to the Soviets one by one, and once China and the Soviet Union turned their faces in the future, where would China still have a way to live? Not only Jiang Baili and others looked at each other, but Lao Jiang himself was also a little hesitant.

Regardless of Lao Jiang's hesitation, Liu Yun dispelled everyone's doubts with just one sentence.

"I don't know whether China and the Soviet Union will go to war, but I know that the three northeastern provinces have fallen into the hands of the Japanese invaders, and even if China and the Soviet Union really want to go to war, it will be after recovering the northeast, so it is still important to resist Japan at the moment."

Lao Jiang and the others suddenly opened.

Yes, there was a territorial dispute between China and the Soviet Union, but now everything is false, the Japanese devils are almost in Nanjing, and it is too late to say anything, not to mention that it is just through the matter of "borrowing generals" to show the Soviets China's sincerity for "future peace".

It's a lot of work, a clever plan.

As for the issue of heavy artillery, Lao Jiang and the others were really dumbfounded.

Among the millions of Chinese troops, even 75-mm mountain guns are still a rarity, and except for the wealthy Central Army, few warlords have been able to popularize the regimental level.

What is the caliber of more than 100 mm, and there are as many as a thousand, should you buy Chinese cabbage?

Bai Chongxi still knew the holy will, and explained to Commander Liu with some self-deprecation, "The Central Army is all 75 mm mountain artillery, and above 100 mm, there are only about 100 new guns, and the rest are all old guns from decades ago, and in terms of real power, they are not as good as the cutting-edge 75 mm field artillery."

Liu Yun was skeptical.

The guy asked a little openly, "Won't it?" I remember that a few years ago, didn't Nanjing import a batch of heavy artillery from Germany, is it also fake? For example, the 10th Artillery Regiment, the FH-18 32/L 150mm heavy howitzer, has a maximum range of 17,400 meters".

The question is too direct, how do you ask Lao Jiang to answer?

Jiang Baili was more righteous, and with a dry cough, he took over the topic, "Yicheng, you stay in western Sichuan all the year round, and you don't know anything about Nanjing at all."

"Well, let's put it this way, Nanjing, Shanghai and other places are too prosperous, and it is relatively easy to leak secrets, and it is not suitable where to train artillery, so I had to transport these precious heavy artillery to Wuhan and Changsha."

"Moreover, the total number is only forty or fifty."

Commander Liu was dumbfounded.

It is no wonder that in another time and space, in the entire battle of Songhu, there was no trace of German-made 150 mm heavy artillery, which had already been pulled to Wuhan and Changsha, so that when the Japanese devils launched an attack, they were always worried, for fear of being attacked by heavy artillery clusters, and in the end they always tried in vain.

Later generations of Internet sailors thought that the heavy artillery had been blown up by Japanese planes, but it turned out that this was the case.

Cannons are used to kill the enemy, like Lao Jiang hiding his armpits, what is the picture?

If this batch of German-made heavy artillery could join the Songhu battlefield in time, how could the devils occupy Shanghai and Nanjing so easily.

For Liu Yun's many questions, Lao Jiang was also sweating profusely, and explained with a wry smile, "The cost of this batch of heavy artillery is secondary, the key is that Huaxia can't make it itself, and the Germans won't sell it anymore."

Liu Yun was also sad, 40,000 compatriots could not make a 150-mm heavy artillery.

In addition, Lao Jiang may have said a little less, because Huaxia can't even make 150 mm shells, and Germany's original artillery shells are one shot and one less shot, no wonder they are only hidden as a national treasure.

Anyway, Commander Liu is no longer entangled in heavy artillery.

He asked with some eagerness, "What about the people who use heavy artillery?" After the return of heavy artillery from Germany, we should have trained quite a few artillerymen, and what about these artillerymen? ”

"Because you need enough artillery, a thousand cannons, to play your due power."

"Ah——, you mean?".

Or Lao Jiang reacted quickly, immediately grasped the key point, and asked with some regret, "Your Western Sichuan Arsenal can produce 150 mm cannons, and up to 1,000 guns?" ”

"Yicheng, you've done something bad."

"Why didn't you say it earlier? If we can equip more than a dozen 150-mm heavy artillery regiments, how can we be afraid that they will invade China by Japanese devils, it is better now, even with these heavy artillery, there will not be enough artillery available."

Liu Yun is also helpless, he is not an immortal, how can he be considered a last resort.

He had no choice but to roll his eyes and go straight to the point, "Headmaster, you can go through the bottom, if you can produce 150 mm heavy artillery, how many can Huaxia use, and if you change to 122 mm heavy guns, how many can you equip?" ”

This can make Lao Jiang confused, he is not a big man in the Republic of China, or the president of the Republic of China, but he does not know everything, and it is good to know everything.

When it comes to heavy artillery, General Xue Yue knows best.

Because of Lao Jiang's family background, he has long been remembered by this guy, "Well, at present, the 150-mm heavy artillery artillery has been trained in rotation three times, and three heavy artillery regiments can be formed, each regiment is equipped with 48 heavy guns, each regiment has jurisdiction over three artillery battalions, each battalion has jurisdiction over two artillery companies, each company has jurisdiction over four artillery squads, and each squad serves one heavy artillery."

What's going on with this heavy artillery, isn't it the "three-three system" that is implemented, such as three squads and one platoon, three platoons and one company, and three companies and one battalion, how did it come to Lao Chiang's artillery regiment, and it changed when it was said to have changed?

Before Commander Liu could speak, Xue Boling, who was thinking about the heavy artillery in western Sichuan, opened his mouth to explain.

"Because the three-three system is a commonly used grouping system for infantry units, while the artillery grouping is derived from the British system and follows the two-two system, which was used to be called - artillery group, formation, squad, squadron, brigade, wing and corps, etc."

"Now it's just a different way of saying, in fact, it's a change of soup and not a change of medicine."

As soon as he said this, Liu Yun immediately understood that the original artillery squad should not be called an artillery squad, but an "artillery group", which was easily confused with the ammunition group, the transport group, and the observation group, so it was changed to an artillery squad.

In the same way, an artillery formation has only two cannons, and when it is put on the battlefield, it does not know what it is used for, and it seems that the light and heavy machine guns that want to clear the enemy at fixed points have been replaced by mortars, and the Japanese devils are even more economical, and they have changed to grenadiers to take charge of this matter.

At the beginning of the 20 th century, due to the rise of dreadnoughts and super dreadnoughts, the navies of various countries used "facts" to tell the world that the effectiveness of "all-heavy artillery warships" was more than three times that of old warships, and the warships should be equipped with more than eight super heavy guns of the same caliber and firing range.

In order to improve the accuracy of the shelling, it is better to use a salvo or half a salvo, and if it is a half salvo, it should be more than four.

However, the revolution of the Navy's dreadnoughts also led to a revolution in army artillery.

Therefore, a complete artillery unit should have eight cannons, for the sake of insurance, it is better to have sixteen guns, and one and a half salvos is eight, which is just the minimum requirement for the number of cannons in the theory of full heavy artillery of the navy.

In this way, eight cannons just made up an artillery squadron, and two squadrons just formed an artillery group.

Western Sichuan can produce heavy artillery, and Commander Liu is the commander.

General Xue Yue (lieutenant general plus general) is one of the advocates of the formation of a heavy artillery group in the Republic of China, but whenever someone has questions, he will explain them one by one, and even half a salvo has given detailed answers.

To put it simply, the main purpose of the half-salvo is twofold: one is to increase the rate of fire, because the smaller the team, the faster the rate of fire, and the other is to facilitate the observation of the shelling situation so that the ballistic elements can be corrected in time.

Liu Yun is a layman anyway, he has only been trained in the army of Nanjing Lu University, and what Xue Yue said is too professional, and he seems to understand it.

But in general, he understood all the doubts in the development of the 173 mm cannon, and he finally understood them all, such as a large number of propellant packs in the shells, he never understood why the manual marked 0-9 dosing.

It turns out that the No. 0 dosing is to add the full amount of the propellant pack, for example, ten pill packs, one can not be less, and then each additional number, one more pill pack will be drawn out, if the No. 3 dosing is needed, three pill packs will be drawn until the No. 9 is added, and one medicine bag is left.

After all the problems were settled, Xue Yue salivated and asked, "Brother Yicheng, do you see when it is appropriate to send a thousand heavy artillery pieces to Nanjing, well, of course, Wuhan is also fine, if you take the railway, it will be a pity if it is blown up by the Japanese devil's plane or spies."

A thousand heavy guns?

Liu Yun really didn't bother to pay attention to him.

He sat down in front of the sand table and pondered for several minutes before changing the topic and asking, "Brother Boling, if we change to a 122mm howitzer, how many artillery regiments can we currently form?" Well, I mean the kind that can be put into the Songhu battlefield."

These words made Lao Jiang and the others blush.

However, Commander Liu has aircraft artillery in hand, and he is the real uncle.

had to let Bai Chongxi come out and sing a big face, "Brother Yicheng, this thing is not difficult to say, but the basic principle is the same, it only takes a few months of training, and more than a dozen artillery regiments can be formed, of course, if you want to put it into use in a hurry, five or six regiments is the limit."

Liu Yun silently calculated in his heart.

An artillery regiment, when it is fully counted, is only 48 heavy guns, if it is calculated according to ten 122-mm heavy artillery regiments, it is about 500 guns, as for the 150-mm heavy artillery regiment, even if the number is doubled as Xue Yue said, there are only 5 regiments, and there are about 250 guns.
