Xu Jun's database does not have drawings for this grenade gun, but NATO also bought a lot of American machinery back then. How could this thing be missing in the museum? To be honest, the technical content of the entire system is not very high. Of course, this is only for some developed industrial countries. If it is a country with relatively backward materials and processing technology, it is really difficult to reversely imitate it.

Its biggest difficulty is that it has very high requirements for processing accuracy on special ammunition. Without large-scale precision manufacturing technology, it is difficult to control the quality of the product. If the defective rate remains high, it will seriously affect its production cost. When the cost-effectiveness ratio exceeds a certain psychological value, this weapon will lose its value in equipment, because there will be a bunch of cheaper solutions to replace it, such as gun-fired grenades and recoil-free cannons, or various grenade ejectors.

Germany's precision machining technology was at the forefront of Europe at that time, so of course there would be no problem of not being able to produce such ammunition. The 4043mm low-speed grenade equipped by the US military developed a family. Over the past half a century, more than a dozen bullet types with different performance and functions were developed. Even the most basic shells had five or six models, not to mention the various internal charges and various special fuzes.

Xu Junke did not have the idea of ​​copying them all. He now only needs the most basic models. The German army did not fight special security wars, but a traditional regular war.

The German army will fight the enemy face to face, and the opponent is not the mobs in the jungle of Southeast Asia, but regular soldiers who have received systematic military training.

Therefore, the German weapons and ammunition must be suitable for this war model. The two sides compete not only on the number of weapons and the firepower they deploy, but also on the quality of soldiers, the command ability of officers, and the most critical logistics supply capacity.

The models of ammunition must be unified, otherwise it will inevitably cause disasters in the logistics system. Xu Jun prepared four types of ammunition. The first type is the conventional high-explosive killing grenade, which is used to deal with armorless targets. It is loaded with a molded fragment warhead. After the explosion, it can produce more than 200 shrapnel pieces, with a fatal killing area of ​​five meters in diameter, but shrapnel still have a considerable lethality within a range of ten meters.

The second type is anti-armor grenade, which uses hollow charge warheads and can penetrate 50 mm thick armor. This is used to deal with light armored vehicles and steel-plate infantry bunkers. It is a bit difficult to attack medium-sized tanks, so it is best to use professional anti-tank weapons to deal with tanks.

The third type is a white phosphorus-launched smoke cartridge, which is filled with white phosphorus as smoke and burning agent. After the explosion, the white phosphorus inside will spread around, burning and releasing a large amount of white smoke, instantly creating a smoke belt about seven meters in diameter, and can last for about two minutes under weak wind. This smoke bomb is mainly used to attack enemy positions and fortification areas, block the sight of the opponent's firepower points, and at the same time can also set fire in enemy positions, killing and injuring enemy personnel while creating panic and chaos.

The fourth type of ammunition is a flare. After being launched, it detonates in the air about 150 meters. A small parachute with illuminating agent can provide half a minute of lighting time. Don’t think that the time is too short. On a fully alert position, half a minute is enough for soldiers to see the situation in the target area and be prepared for everything to deal with.

Xu Jun predicted that the installation of grenade guns would even change the German urban combat mode. In regular combat, important targets on the enemy's positions would be repeatedly named by various types of artillery and rapid-fire weapons equipped by the German army, which would not leave much room for grenades to play. However, in urban street fighting and densely built areas of the enemy, the value of grenade guns was reflected at that time. It was the best weapon to deal with stubborn enemies in houses and barricades, and to clear a fire point hidden in the houses, that is, one or two grenades.

If the European war continues now, Xu Jun would not have taken out this equipment anyway, because the shells of this ammunition are all made of aluminum alloy die-cast. If Britain's maritime blockade was not broken, then Germany would not be able to consume the materials for making this ammunition.

Europe lacked aluminum ore. At that time, only Hungary and France had large-scale bauxite ore. However, in 1940, the combined bauxite output of the two countries did not exceed one million tons, which could not meet the needs of the whole Europe at all. Therefore, every year, Europe needed to import a large amount of aluminum from South America and Southeast Asian colonies, and the main production areas were Suriname and Indochina of the Netherlands.

Refining aluminum requires a lot of electricity, which is not affordable by non-industrial countries. Germany's Ruhr Industrial Zone has strong smelting capabilities, and it is also because several nearby large hydropower stations and thermal power stations provide sufficient energy. Therefore, as long as Germany obtains raw materials, the output is not a problem at all.

Now Germany has escaped the dilemma in history and is no longer troubled by lack of materials. As long as it is willing to spend money, aluminum can be said to have as much as it wants. (Xu Jun: We are pure Europeans, if you don’t believe it, I will build a h39 immediately for you to see. Weirler: Don’t be impulsive, head of state! ∑(っ°Д°;)っ)

Moreover, the head of state was not only satisfied with imports. He had long turned his greedy eyes to the rich African land. Guinea is currently a French colony. This country has the largest bauxite deposit in the world. It explored alone has 7.4 billion tons, accounting for a quarter of the world's bauxite reserves.

How could Xu Jun leave a bunch of treasures without developing it? At present, almost all of Africa is European colonies. There were no black people's rights organizations at this time. American blacks were still sitting in the isolation area of ​​the bus. Any plundering of Africa was consistent with the values ​​of the time. Oppressing workers of color was regarded as a natural power in the entire European and American culture.

Germany has obtained the power to explore and mine minerals in colonies such as Africa, Britain, France, Italy, and Portugal. Of course, it is not for nothing. Germany will also give shares in the other party's enterprises to deduct funds for land purchase.

Xu Jun has a batch of valuable mineral information in his hands, which greatly saves exploration time and funds. Some of them can be mined only by mechanical entry. The biggest cost is consumed in the transportation of ores. However, for Europeans with advanced road construction technology, building a road or railway is not a difficult task, and it only costs manpower and money.

The European war has damaged the vitality of major capitalist countries, and the wild beasts are all hungry. Perhaps they can still pretend to be a group of gentlemen in the civilized world, but when they go to the wild Africa, they will unscrupulously expose their true colors. Behind the prosperous cityscape of Europe, there are countless African corpses buried.

Xu Jun is called the apostle of God, not a Virgin. He will not jump out and talk about freedom and human rights. As a fascist dictator, saying that kind of words will make people feel that he is playing irony.

If he could not overcome this current hurdle, his own survival would be difficult to guarantee, so he could not care about the rights and interests of the African people. Of course, he would restrict certain behaviors during the plundering process and invest as much as possible in some local infrastructure, which would be considered a little reward.

Going back, Germany currently has no shortage of raw materials, steel, aluminum, oil and bombs, and the only thing that is lacking is the time to convert these resources into actual combat power.

The 40mm grenade is still on the drawings. Krupp's technicians have carried out a series of related experiments, such as safety fuses with complex structures. In fact, the safety fuses used by Americans in history are not a newly developed technology. Inertial insurance technology has long been used in various anti-aircraft gun fuzes. Even grenades designed in Italy have also used inertial insurance.

Simply put, due to the rifle, the warhead starts to rotate continuously after leaving the muzzle. The inertia generated during rotation causes the internal structure of the fuse to rotate. Until the warhead rotates for a predetermined number of turns, the guide hole between the firing needle and the fire cap is finally connected into a line, and the movement of the firing needle is no longer blocked. At this time, the fuse enters a combat state.

Speaking of which, the whole process seems to be very long, but in fact it only takes a few fractions of a second. At this time, the grenade flies out about three meters away. Hitting an obstacle within this distance will not detonate the grenade, avoiding accidents that hurt your own people.

Xu Jun made up his mind to arm his soldiers to his teeth, whether metaphorically or literally, in his opinion, if consuming a ton of steel can save a soldier's life, then consuming it. At that time, he will be able to gain a veteran with practical experience, which is more valuable than 100 tons of steel at some point.
