"Your Royal Highness the Prince, according to the plan you formulated, we have designed a total of two types of tanks in this tank tender, the first type of tank is called the breakthrough tank, which has strong firepower and heavy armor, can resist the attack of the enemy's general firearms, can destroy the opponent's firepower points, and guide the troops to break through the enemy's defensive positions and fortified areas.

"The second type of tank is the assault tank, which is poorly armed and has a worse defense than the former, but it travels long enough and has better stability, and its role is to lead cavalry and fast troops to penetrate in depth after breaking through the gap in the tank. And provide fire support to the infantry within its capabilities. ”

"For these two projects, Bavaria Southern Industry has put forward a total of four proposals according to your suggestions, two plans for the breakthrough tank and two plans for the assault tank, and the four prototypes have been tested at the test site for a week, and you can visit them at any time." Maj. Gen. Schmidt reported.

"Very good, hand in the relevant technical documents, and then arrange it, I will be there on time at 9 o'clock in the morning the day after tomorrow!" The prince pondered for a moment and then said.

Although the tank was in its cradle during the First World War, and the technical reserves in all aspects were very limited, as a traverser, the prince still had a general understanding of the performance of the 1 battle tank, and in terms of power, not to mention anything else, at least a 100-horsepower diesel engine was not a big problem. In terms of weight, according to the British MK1 tank, it is also possible to build a tank of 25 to 30 tons. Of course, in the case of such extreme weight, the speed of the tank should not be very high, and it would be good to be able to run the speed of an ordinary bicycle on the road and the speed of an infantry in the field.

The prince, of course, did not design a tank according to such extreme data, on the one hand, it was unnecessary, and on the other hand, it did not correspond to the needs. This kind of tank is mainly used on the Eastern Front, if you put it on the Western Front, whether it is the French 75 rapid-fire gun or a variety of other caliber artillery, dense mines, or close-fire large-caliber howitzers will be the nightmare of this plane tank, although the British tanks on the Western Front have achieved some good results in history, but that is also achieved in the comprehensive situation of superior air force, superior artillery, and superior forces. The Germans were inferior on all three fronts, and the prince believed that with tanks the situation would not have changed radically.

Compared with the Western Front, whose firepower can be called BT, the situation on the Eastern Front is much better, on the one hand, the Russians have less artillery, on the other hand, the battle line is long, and the density of firepower is estimated to drop directly to less than one-sixth of the Western Front! The defenders' 3-inch guns were quickly destroyed by the concentrated tanks. Therefore, the design of tanks aimed at the Russians should emphasize on the one hand that they are cheap and suitable for mass production, and on the other hand, they should be stable, after all, the transportation situation in Russia is very bad. And in order to adapt to the tragic road conditions in Russia, the weight of the tank itself should not be excessive. There is no too strong fire threat, but high stability is required, and in the end, the prince's technology on both tanks is as follows.

For assault tanks, the frontal armor should be at least about 45mm thick, and it is better to have a certain angle of inclination. Theoretically, it was necessary to be able to block the grenade attack of the 3-inch rapid-fire guns that the Russians were heavily equipped. As for armor-piercing shells, this thing can only be at the mercy of God, at least not now, because if nothing else, the prince does not know whether the 76.2mm rapid-fire guns of the Russians in history have armor-piercing shells, nor how thick the armor-piercing shells can penetrate the armor ....... The flanks also need to have a certain amount of defense, at least to be able to defend against attacks such as 47mm small-caliber guns.

In terms of firepower, the prince has a total of three alternatives, one of which is the 50mm gun currently used by the German Navy, weighing 280 kg and having a barrel length of 40L. The weight of the shell is 1.75kg. Rate of fire 10 rounds a minute. Has some anti-armor capabilities. Although this ability is not very important.

The second option is to equip a 75mml24 gun! That's right, this is a light gun made by the Bavarian rapid-fire gun with a truncated barrel, although the muzzle velocity is very low, but the shell weight is large enough, 7.5kg! Because of the use of new gun mounts, the rate of fire was more than 6 rounds a minute, even in a relatively closed fighting room. It can take care of both anti-armor and anti-infantry tasks. The only problem was that the gun was relatively heavy, the gun weighed 430kg. (This data is fabricated by the author, who found out that the 12-pounder gun L40 gun used by the British Navy weighs 510kg, so here is an estimate.) ）

And the third option is to use the 75mm rapid-fire guns of the army units directly. The basic data is the same as the second option, except that the muzzle velocity is higher, and it is more effective against hard targets.

In addition to the main armament, this breakthrough tank will be equipped with two machine guns as auxiliary weapons, one of which will be placed on the top of the turret, and the other, in principle, on the nose. Or alongside artillery. Considering the importance of machine guns in the 1st World War, each machine gun had about 1500 rounds of ammunition.

The final positioning tonnage of such a tank is about 15-18 tons. The power used is now an 80 hp engine with a leaf spring suspension. The maximum speed on the road is around 10 to 15 kilometers per hour. The off-road speed does not exceed 5 km/h visually. The maximum distance is currently said to be about 50 kilometers .......

The other type of assault tank can actually be seen as a small tank similar to the FT17, weighing no more than 10 tons, and armed with a machine gun or a small-caliber rapid-fire gun. This kind of combat vehicle basically does not have the ability to attack fortifications, but the weight is small, cheap, the key is to require relatively high stability, the journey is about 150 kilometers! The speed of this small vehicle is actually not very fast, and it is basically comparable to the performance of the Breakthrough vehicle. As for defense, the front is no more than 10mm of armor, and the thickness of the side and rear armor is 6mm. Only protection against machine-gun fire and grenade shrapnel.

And in terms of weapons, there are also two combinations, the first is to install 2 machine guns. Used as specialized anti-infantry fire, it has about 4,800 rounds of ammunition and a crew of 2 people. The second combination is to mount a 37mm cannon that fires 0.5kg shells. The reserve ammunition is around 120 rounds.

Of course, all this is the prince's request, and in fact how it will depend on the situation at the Bavarian State Proving Ground the day after tomorrow. The next day, the prince also received a report from Schmidt, saying that in addition to the kingdom's normal tender products, Bavarian Southern Industries had specially designed several other vehicles for the prince's review, which made the prince very interested. He wanted to know what kind of things Daimler and Maybach, the two future engine giants, could make!
