Beiyang 1917

In mid-July 1918, the Zhonghua Fudao Automobile Company, headquartered in Nanyuan, Beijing, China, officially produced the latest model of the Zhonghua FD-7 light tank. Before that, in early July 18, the Zhonghua Fudao Automobile Company's The production capacity has been expanded, with the monthly production capacity of 1918 Dodge military trucks, 7 fd-1500ii wheeled armored combat vehicles and 17 Chinese Hummer off-road vehicles. (.)<The Nanyuan Automobile Industry Base was built like bamboo shoots, and the engine branch factory was expanded by more than three times. Zhonghua Fudao Automobile Co., Ltd. became the largest military and civilian automobile manufacturing group in Asia.

而1918年4月底定型，五月开始正式投产的中华悍马越野车，在整个五月份生产了800辆、到了6月份则生产了1200辆、预计七月份的产量将确保达到1500辆。

The basic performance parameters of this Chinese Hummer fj-18 off-road vehicle are as follows:

1. Equipped with Ford 2.9-displacement inline 4-cylinder air-cooled engine,

2. 4x4 drive, three-speed transmission,

3. The body is low, the chassis is formed and pressed by steel at one time, and the front and rear wheel bridge spring steel plates are du li suspended.

4. The weight of the whole vehicle is only 860 kg, the length of the vehicle is 3 meters, the height is 1.87 meters, and the width is 1.57 meters.

5. The maximum speed is 80 kilometers per hour, and the load is 450 kilograms.

6、既可以作为侦察指挥车、又可以搭载机枪作为火力支援平台，安装枪架和气冷式7.62mm口径m1917a3勃朗宁重机枪，也能安装新12.7mm大口径型m2勃朗宁重机枪。

The Chinese Humvee fj-18 off-road vehicle has in fact become the basic vehicle for the reconnaissance troops of the coalition forces and commanders above the company level. The infantry armies of the central yang front army will also successively equip this "BMW" mount, which is most envied and loved by the soldiers of the frontline coalition forces.

When the coalition army was first established in Novosibirsk, the Chinese Hummer FJ-18 reconnaissance command vehicle equipped by the Chinese Third Army in the coalition army had already made the generals of the Japanese army at all levels look eagerly. You must know the three of the Japanese Third Army Division, but even the commander of the brigade is still riding a horse without a car, and the center officer in the coalition army is actually the one who equipped this short, sturdy and domineering Hummer command vehicle to the level of the battalion and company commander. This is called the Imperial Army How embarrassing are the warrior commanders on horseback? !

The establishment of the Sino-Ri Alliance enabled Japan to get rid of the pressure on the development of the country brought about by the lack of resources for the first time. As early as the beginning of May, the fifth deep well "Zhongmei No. 3328" in the Renqiu Oilfield of China and the United States was successfully drilled, with a depth of 1200 meters. , ri produces 6700 tons of crude oil, which means that Renqiu Oilfield already has five high-yield oil wells at the same time, adding up to 46900 tons of crude oil produced in ri, or 240 barrels, with an annual output of more than 20 million tons of crude oil, and China's crude oil exports to ri are also large The rate increased to more than [-] barrels per month.

The whole of Asia is lit up in the night sky by the oil and fuel produced by China's Renqiu Oilfield. The major cities and villages in Japan, thanks to the high-quality and low-cost oil and fuel supplied by China's big brother of the China-Ri Alliance, the lights at night It is also shining brightly, and Renqiu high-quality kerosene produced in China has become the first choice for civilian lamp oil and fuel oil in the entire Asian region.

And at this moment in late July 1918, the coking coal from Ordos, China and the iron ore from Baiyun Obo, China, can already pass through the 7-kilometer railway branch line and converge at the Baotou Iron and Steel Base for smelting. Like the Xuanhua Iron and Steel Base, the Baotou Iron and Steel Base of China Iron and Steel Company The coal-fired power plant, ironmaking, steelmaking, coking and other branch factories have been put into operation at the end of July, and the first phase of the trial production of Baiyun Obo Iron Mine has an annual output of 90 million tons of iron ore. (.)

而包头炼铁厂除了第一座450吨高炉已安装生产之外，第二第三座450吨高炉在7月下旬也提前完成了安装调试投入生产。ri产生铁达到了设计中的1500吨，预计年产生铁45万吨以上。

The first phase of Baotou Steelmaking Plant has four 140-ton open hearth furnaces with an annual output of 20 tons of steel, and four 5-ton electric furnaces for smelting alloy steel, gun-tube steel and tool steel, with an annual output of alloy steel, gun-tube steel and other special steels 7500 tons, the first phase of the project has been completed before the end of July and reached the expected production capacity.

In the second half of the year, the second phase of the Baotou Iron and Steel Joint Base will continue. By the end of the year, the iron ore production capacity will be expanded to 180 million tons per year, and the annual production of pig iron and crude steel will be doubled to 90 tons and 40 tons. , The annual output of special steel for electric furnace is increased to 1.5 tons.

The steel production capacity of Xuanhua Iron and Steel Base effectively guarantees the production of arms, weapons and ammunition of Xuanhua Arsenal, the production of engines, tanks, armored vehicles and automobiles of China Fudao Automobile Company, and the production of engines and aircraft of China Aircraft Manufacturing Company.

Of course, the biggest good news in July is still the official launch of the Chinese fd-18 light tank. As a magical weapon for equipping and forming tank brigades, the Chinese fd-18 light tank was born ahead of schedule, and the Xuanhua Arsenal completed ahead of schedule. The development of the M1918-37mm new high-speed tank gun is closely related.

早在1918年3月，在从美国引进了50辆ft-17雷诺轻型坦克样车后，同时也随着3月底，宣化兵工厂的75mm山炮、75mm野炮、150mm榴弹炮以及60mm和81mm两种迫击炮的仿制成功，当时王庚给兵工厂新出的题目：就是在法国雷诺ft-17轻型坦克上所使用的37mm短管炮的基础上，研发一门新型的37mm口径的高she反坦克两用炮。

Due to the low muzzle velocity of the 17mm short-barreled howitzer used on the French Renault ft-37 light tank, it has almost no penetration ability, and can only cause damage to personnel and light fortifications exposed outside the fortifications. Wang Geng's request at the time Yes, refer to the French 37mm short-barreled gun, plus the basis of the French Hatkis 37mm rapid-fire gun, plus the basis of the 75mm mountain gun (cannon).

The artillery workshop of China's Xuanhua Armory must develop a new Chinese-made 37mm high-shelf anti-tank dual-purpose gun on the basis of the above. Lengthening the barrel and improving ammunition are obviously the key to increasing the chamber pressure, muzzle velocity and firing range. Wang Geng It is required that the 37mm high-shelf anti-tank dual-purpose gun under development has a maximum launch height of not less than 5000m, and can penetrate 1500mm thick armor within 48 meters on flat ground.

More importantly, the weight of this gun will not exceed 450 kilograms, and the firing speed will not be lower than 20 rounds per minute.The main basis for Wang Geng’s reference is the parameters of 37mm caliber anti-tank guns that were generally equipped in various countries after World War I in the previous life. Tank guns appear.

At that time, if it was not designed to accommodate the Chinese fd-18 light tank under development with a total weight of six tons, Wang Geng originally wanted to design a 75mm caliber high-shelf dual-purpose anti-tank gun, but in that way, the weight of this gun would be at least It also needs to be more than 2.5 tons, and a 6-ton tank gun on a tank with a total weight of only 2.5 tons is completely a small horse-drawn cart. For the participating troops who have always emphasized mobility, they can only be released first.

Don't underestimate the 37mm anti-aircraft gun. As a classic of small-caliber anti-aircraft guns, in Wang Geng's previous life, a century later, the 37mm anti-aircraft gun is still the main weapon of the reserve anti-aircraft artillery unit. In the previous life, in the early stage of the outbreak of World War II, before the emergence of heavy tanks, the 37mm anti-tank gun was still the best anti-tank weapon.

The American, British and French engineers and designers in the gun workshop of Xuanhua Arsenal, together with Chinese ordnance experts mobilized and collected from arsenals all over the country by the Ordnance Industry Department of the Army Ministry, worked hard day and night to form more than ten teams to carry out different parts of the technology. To tackle key problems, on the basis of a large number of experiments and tests, it took three months before and after, and finally designed a new type of 37mm caliber series high-shelf anti-tank tank gun according to Wang Geng's request.

在新型37mm炮系列研制的过程中，由于之前12.7mm大口径m2勃朗宁重机枪已经提前问世并正式在联军中列装，因此宣化兵工厂首先完成she击定xing的是中华fd-18轻型坦克亟待装备的37mm坦克炮。

The performance parameters of the 1918mm tank gun that was finalized as m37-37-t are as follows:

1. Barrel diameter: 37mm

2. Barrel length: 1739mm (l47, barrel length is 47 times the caliber)

3. The weight of the whole gun: 372kg

4. Number of operators: 2 (one loader, one commander and gunner)

5. High and low range: -5°to+25°

6. Shooting speed: 15 minutes

5. The muzzle velocity of the gun: 762ms (2,500fts)

6. Effective range: 1,500m (1,600yd)

7. Maximum range: 5,500m (6,014yd)

The 37mm tank gun is equipped with the 37mm caliber m1918-apc armor-piercing grenade and m1918-hc high-explosive grenade specially developed by the arsenal at the same time.

The parameters of the m1918-apc armor-piercing grenade are as follows:

1. The overall length is 337mm, the overall weight is 1.32kg, and there is a tracer tube at the tail of the warhead;

2、弹头涂黑se,长98.98mm,弹体直径36.75mm,弹带直径38.15mm,底部直径13.05,底部到弹带距离14.27mm,

3. The warhead weighs 681g, of which the charge is 13g, and the composition is RDX high explosive. There is a red mark on the projectile body to indicate that it is an armor-piercing projectile;

4. The length of the cartridge is 247.65e, commonly known as nitroglycerin and nitrocellulose; both weigh 188g

The parameters of the m1918-hc high-explosive grenade are as follows:

1. The overall length is 343mm, the overall weight is 1.29kg, and there is a large tracer tube at the tail of the warhead;

2、弹头涂银灰se并有一道黄圈,长129mm,弹体直径36.78mm,弹带直径40.61mm,弹带宽度8.38mm,

3、弹头重617g,其中装药23.2g,成分为黑索金高爆炸药,引信为az-18-1型(黄se弹尖)或者az-18-2.型(红se弹尖);

4、药筒长247.65mm,瓶颈直径38.1mm,斜肩直径41.27me)和硝·化棉(nitrocellulose),重175g

Then the performance parameters of the 1918mm anti-tank gun that was finalized as m37-37-at are as follows:

1. Barrel diameter: 37mm

2. Barrel length: 1665mm (l45, barrel length is 45 times the caliber)

3. The weight of the whole gun: 450kg

4. Number of operators: 2 (one loader, one gunner)

5. High and low range: -5°to+25°

6. Shooting speed: 15 minutes

5. The muzzle velocity of the gun: 762ms (2,500fts)

6. Effective range: 500m (1,600yd)

7. Maximum range: 5,500m (7108yd)

Speaking of which, the basic parameters of this 37mm tank gun and anti-tank gun are the same, except that the barrel of the anti-tank gun is slightly shorter, and it is equipped with a shield, a gun mount and two large inflatable tires for towing and towing. Compared with the German flak 37mm anti-tank gun in Geng's previous life, it was loaded from the semi-automatic bolt behind the shield instead of from the front of the barrel under the enemy's fire, which greatly improved its survivability.

Among the three new 37mm series guns in Xuanhua Arsenal, the last one successfully developed is the M1918-37-aa single-barreled anti-aircraft gun, which is installed on a special chassis that can rotate 360 ​​degrees.

1. Barrel diameter: 37mm

2. Barrel length: 2315mm (l62, barrel length is 62 times the caliber)

3. The weight of the whole gun: marching state 1350kg; combat state: 1240kg

4. Number of operators: 6 people

5. High and low range: -15°to+85°

6. Shooting speed: 150 minutes

5. The muzzle velocity of the gun: 762ms (2,500fts)

6. Effective sheight: 4500m (4,921yd)

7. Maximum range: 6,500m (7108yd)

The gun workshop of Xuanhua Armory can produce the above-mentioned three types of 37mm guns at a rate of 7 per month starting from July. According to the priority level, the double-mounted 600mm high-level dual-purpose machine gun can already meet the requirements. The air defense needs of the army, so starting from the official production in July, 12.7mm tank guns and anti-tank guns will be put into mass production first. The she cannon is only scheduled to produce 7 pieces.
