PS: The second update arrives, ask for collections, ask for recommendation votes, ask for rewards! Thank you for the tips from book friends 120404073106044 5 and book friends! Now Jilin is still too weak, although with Heilongjiang added, there are already hundreds of thousands of square kilometers of land and tens of millions of people. However, in the eyes of the Americans, Jilin and Heilongjiang, which have a weak industrial base and backward economies, are not qualified to cooperate with the United States.

Although the United States also needed to support a power to deal with the expansion of the Japanese. However, the current Jilin is not a very good choice. Unless the Wu family can defeat Zhang Yuting and Feng Linge and dominate the entire Northeast. In this case, having a land of 1.2 million square kilometers and a population of 20 million can be regarded as having a certain strength.

After all, the entire Tohoku territory is more than three times the size of Japan. The population is only 40 percent of Japan's. However, the Northeast is vast and rich in resources. If we can get the support of the United States, we will certainly be able to achieve rapid development. In this case, it may not be possible to lose the strength to contain Japan. Not to mention that if one day the Wu family can enter the Guannei and control the whole of China, it will be more beneficial to the United States.

Although Pierre Dupont and David Rockefeller were not politicians, they had a very precise grasp of the national policy of the United States. In fact, the national policy of the United States is basically formulated by these big capitalists. The president of the White House is more of a proxy for them.

The two promised Wu Haoxuan that as long as the Wu family could control the entire Northeast and resist the Japanese counterattack. Then, they will persuade the family to help the Northeast as much as possible. Even, it is not impossible for the United States to make a big effort to support the Northeast.

After seeing off Pierre Dupont and David Rockefeller, Wu Haoxuan began to be busy again. As the situation in the northeast becomes more and more tense, the Jilin Army must be ready for battle. In particular, the armed forces, which have just completed their expansion, need to step up their training so that they can form combat effectiveness at an early date.

"With the support of the United States, we may be able to do more with less. The Americans have abundant funds, and with their support, they should soon be able to lay an industrial foundation in the Northeast. At that time, there will be capital to confront the Japanese. Wu Haoxuan thought secretly.

With the help of the United States in the early stage of development, this is a plan that he has set up a long time ago. It's also a shortcut. After all, it is undoubtedly difficult for poor and backward China to develop industry, especially heavy industry. Without ten or twenty years, it is simply impossible. Under the internal and external troubles, it is impossible for China to get so much time.

But with the help of the United States, it will be completely different. It is possible to cut this time by more than half.

Although, the Americans are also uneasy and well-intentioned, and this is just to let China drag Japan down. If Japan is really trampled underfoot, I am afraid that China and the United States will once again go against each other for the sake of Pacific interests. However, Wu Haoxuan didn't care at all. The Americans benefit him, so isn't he taking advantage of the United States? As long as China's industry can develop, it will certainly be able to develop rapidly with its abundant resources and huge domestic market. Not to mention the opportunity to make a windfall in World War I. At that time, China may not be afraid of the Americans!

"To obtain the qualifications to cooperate with the Americans, it seems that it is necessary to win Zhang Yuting and Feng Linge and unify the Northeast. You have to resist the Japanese counterattack. It's not easy! Although this seemed to be very difficult, Wu Haoxuan also knew that they had no other way, and there was no way back, so they could only go all the way to the dark.

"Your Excellency Chief of Staff, I have identified a problem that may have an impact on the next phase of our operations." A Caucasian man wearing a colonel's uniform of the Jilin Army appeared in front of Wu Haoxuan. He is Wu Haoxuan's classmate, Colonel Harry, who is currently the head of the Operations Department of the General Staff Headquarters of the Jilin Army. It's just that compared to James, Harry is a little more old-fashioned.

"What's wrong? Harry. Any questions? Wu Haoxuan asked.

"The current twelve infantry divisions of the Jilin Army are already world-class. However, in terms of heavy artillery, there is still a blank slate. In this regard, I think it needs to be strengthened. Harry said.

"Heavy artillery? Isn't it enough that each infantry division has an artillery battalion armed with 36 105-mm light howitzers? Wu Haoxuan frowned. For field troops, heavy artillery is not conducive to rapid maneuvering. Therefore, the artillery used in field battles is often light artillery, mainly field artillery or mountain artillery with a caliber of about 75 mm. Cannons with a caliber of more than 100 mm are much heavier. Of course, the power is not comparable to that of a 75 mm cannon. It was precisely because of the schedule that Wu Haoxuan gritted his teeth and equipped each infantry division with 36 105-mm light howitzers. This makes the artillery of the Jilin Army already have a great advantage.

"The power of the 105-mm light howitzer is good. At least when dealing with the Mukden Army and the Rehe Army, it is enough. However, according to the plan of the Fundamental Staff Headquarters, once the Jilin Army unified the Northeast, the Japanese would most likely immediately turn around and launch an attack on the Jilin Army. The threat of the Japanese Army is much greater than that of the Mukden Army and the Rehe Army. Harry shook his head.

"The Japanese Army is not equipped with many large-caliber artillery pieces, right? In the last Russo-Japanese War, the most common artillery used by the Japanese Army was the 31-year 75mm rapid-fire gun. In terms of rate of fire, it is inferior to our 75-mm field guns, not to mention our 105-mm light howitzers. Artillery with a caliber of more than 100 mm is also extremely lacking in the Japanese Army. Of course, during the Russo-Japanese War, the Japanese also used 280mm heavy howitzers, but that was to attack Arthur and strike at the Russian fortresses. Wu Haoxuan said.

Harry smiled and didn't say anything more. However, at this moment, Wu Haoxuan himself has already understood.

"Damn, it looks like we're really lacking heavy firepower." Wu Haoxuan also came to his senses. In the war to unify the northeast, if the Japanese dared to intervene, the Jilin Army would of course drive the Japanese out of the northeast in one go. The Japanese built a number of forts along the South Manchurian Railway, especially the stations of the six railway garrison brigades. In addition, the Arthur fortress in Kanto Prefecture could not be attacked at all without heavy artillery. Not to mention that the Japanese still have absolute superiority in the navy. If the Japanese Navy shelled the ports of Tohoku, wouldn't it just sit back and wait?

"Harry, do you have any good ideas?" Wu Haoxuan asked with a dark face.

"I built the Jilin Army to build a heavy artillery unit, armed with 155mm heavy howitzers. I checked the information on the 280-mm heavy howitzer that the Japanese army was equipped with, which weighed 26 tons and had a range of 7,650 meters. It's just that this is old-fashioned artillery after all. If it is equipped with a new 155-mm heavy howitzer, it can be suppressed. At least in terms of range, it can steadily suppress these old heavy artillery. In addition, the Jilin Army could be equipped with some train guns to attack the fortress of Lushun. As for the navy to defend the Japanese, it could only rely on the construction of shore defense fortresses and the installation of large-caliber fortress guns. Harry said.

Wu Haoxuan nodded, this is a good construction. The Japanese fortresses in the Kanto region, as well as the Japanese navy, are indeed confidants. Sooner or later, Jilin will also develop its navy. However, at present, the navy is equal to zero, and for a long time, it will not be able to confront the Japanese navy. This can only be a passive defense.

"Harry, I see. I'll arrange the heavy artillery right away. Wu Haoxuan said.

Subsequently, Wu Haoxuan contacted the US arsenal and asked them to ship a batch of the newly manufactured 155mm heavy howitzers. The heavy howitzer was copied only last year, and the prototype was the German Army's 1902 150mm heavy field howitzer. However, Wu Haoxuan's arsenal raised the caliber to 155 mm, and the barrel length was also increased to 16 times the caliber, making the cannon longer than the German-style 150 mm heavy howitzer.

M1905 heavy howitzer with a caliber of 155 mm, a barrel length of 16 times the caliber, a gun weighing 2.5 tons, a shell weighing 45 kg, a muzzle velocity of ammunition 325 meters per second, and a maximum firing range of 10500 meters. With the M1905 heavy howitzer to suppress the heavy artillery of the Japanese, there was no problem at all.

Wu Haoxuan planned to set up a heavy artillery brigade with six artillery battalions under its jurisdiction, plus the troops directly under the brigade, with a total of more than 8,000 people. Six artillery battalions, each armed with 24 155-mm heavy howitzers. In this case, the entire heavy artillery brigade will have 144 155-mm heavy howitzers. However, it is not easy to tow a heavy gun weighing up to 2.5 tons. In addition, the transportation facilities in the Northeast are not very good. I am afraid that there will not be too many opportunities for heavy artillery brigades to go to the battlefield. If you go to war with the Japanese, it will be completely different.

This is just the first heavy artillery brigade formed by Wu Haoxuan. Constrained by the lack of specialized artillery, it was temporarily possible to form only one heavy artillery brigade. When the trained artillery is sufficient, more heavy artillery brigades will be formed to further improve the heavy firepower of the troops.

In addition to heavy howitzers, the Jilin Army also needed larger caliber howitzers, whether it was used to attack Japanese fortifications or to defend against the Japanese navy. It's just that Wu Haoxuan can't produce these heavy artillery in the arsenal in the United States, let alone the domestic arsenal. Come to think of it, or do you have to order from other countries.

The country with the most powerful army in the world is undoubtedly Germany. Not only the plain zhì of their soldiers, but also the weapons that the German Army was equipped with. The artillery used by the German Army is undoubtedly world-class. Otherwise, Wu Haoxuan's arsenal in the United States would not have copied a large number of German-style artillery.
