Manstein and Konrad said they would do it, and immediately started their own production plans.

Conrad's task was to continue to communicate with Qin Chuan to determine the details of the two new equipment, and to transport the personnel and equipment from Germany to Crimea by planes one after another.

The production base was located in Sevastopol, on the one hand, because Sevastopol was very safe, and it had more than a dozen batteries guarding the perimeter, which, as mentioned earlier, could not only bomb the Soviet troops on the Kerch Peninsula but also keep the Soviet Black Sea Fleet at a distance of 44 kilometers.

On the other hand, it was the Germans who captured two shipyards in Sevastopol...... These shipyards fell into German hands almost untouched, and there were even more than a hundred ready-to-use engines in the warehouses.

They were supposed to be like everywhere else, and when the Germans captured them, they were all in ruins or scorched iron, but the exodus of the high-ranking Soviet officials chilled the hearts of the Soviet soldiers, so the Germans were cheapened.

As for the plant for the production of cars, Manstein, after consulting with Colonel Konrad, decided to put it in Kiev for production, and then deliver what was needed by train...... After all, it takes a lot of time to ship an entire production line and raw materials, and there is no need to do it.

As Colonel Conrad had predicted, amphibious tanks were made first.

This amphibious tank is like adding a lifebuoy to the tank body...... When this "lifebuoy" exhausts the gas, it is just an extra circle of plastic around the body, which does not affect the tank battle at all. When it is fully inflated, it has buoyancy, so it can rely on external thrusters to move forward in the seawater.

The first thing the tank crew needs to worry about is the counterweight, if the counterweight is not balanced, for example, if the tank fires a few more shots, it will cause it to move in an inclined attitude in the water, so that the sea water can easily pour into the floating screen and eventually sink the tank.

Of course, there are other dangers, such as the problem of being hit through the floating screen by enemy bullets and shells, as well as the problem of wind and waves, etc., which makes this amphibious tank look too fragile.

"It's hard for me to imagine it going to the battlefield!" Conrad looked at Qin Chuan with some concern and said, "As I said before, its speed is too slow, only five kilometers per hour!" ”

"I know, Colonel!" Qin Chuan replied.

"Do you know what it means to be slow?" "This means that it will be exposed to enemy fire for a long time, and it will be severely inadequately resistant to wind and waves," Conrad said...... A storm can cause it to roll or flood. ”

"The Black Sea is an inland sea!" Qin Chuan replied: "Under normal circumstances, it won't have much wind and waves, and we can also equip it with a drain!" ”

"And what to do with enemy fire?" Conrad asked, "Bullets will pierce these floating screens and make them leak!" ”

"We have drainers!"

"Where's the cannonball?"

Qin Chuan still has the same answer: "We have a drainer!" ”

"God!" Conrad said, "You're crazy! ”

"Don't worry, Colonel!" Manstein looked at the tank with interest and said, "Geniuses are often mistaken for madmen!" ”

Conrad said helplessly: "I thought I was crazy enough, but compared to the captain, ......"

"That's why you're not a genius!" Manstein laughed.

"It seems to be so!" Conrad smiled wryly.

In fact, it was not that Qin Chuan was crazy, but that he was very sure that this tank could play an impressive role on the battlefield...... Neither of these devices was favored at the beginning of their invention:

At the beginning of the invention of the "Duck" amphibious landing ship, it was rejected by the military because it did not look like a serious military equipment, and the practicality of this equipment was discovered because of a chance rescue accident, and then it shined on the battlefield.

The reason why the "Donald Duck" is questioned is that the safety is so poor as Conrad said, and even when the "Donald Duck" is driving in the sea, the collision between the two cars can cause it to lose its balance and enter the water, and finally fall silent...... You must know that the Yankees used the "Sherman" tank to modify.

But the problem is that it is very difficult to get tanks on the shore where the enemy is located in a landing battle, unless the landing force occupies the port, captures the port's equipment, and then hoists the tanks ashore...... However, if this could be done, there would be almost no need for tanks.

The "Donald Duck," on the other hand, can go ashore without the help of any equipment, and as soon as it lands, it can be put into battle to provide firepower and cover for the landing force.

Of course, because of its poor security, it is generally not used for beach-grabbing landing.

The "Duck" landing vehicle was produced in a few days, after all, the shipyard was fully equipped and the hull was ready-made.

Conrad is very satisfied with this equipment, after a few hours of trial operation, Conrad said: "It can carry about 20 people, in fact, its load C capacity is far more than 20 people, its maximum load capacity is 6.5 tons, so we can rest assured that it can be used to carry 105MM caliber howitzers and the shells they need, of course, jeeps are not a problem!" ”

(Note: the total weight of the German-made 105MM caliber howitzer is 1525 kg)

"What's its speed?" Manstein asked.

"80 kilometers per hour on land, 10 kilometers per hour on water!" Conrad replied: "You can travel 354 km and 80 km with a full tank of fuel, respectively!" However, there are some things you have to be aware of before using it to land, such as the sand on the beach is too soft and it will cause it to run aground, so you should try to pack as little stuff as possible and keep the tires low! ”

"Good!" Although Manstein looked calm on the surface, his tone was full of excitement and excitement: "This is exactly what I want, this is exactly what I want...... It was just perfect! ”

Conrad looked at Manstein with a question: "So, we can mass produce?" ”

"Of course!" Manstein replied: "Immediately, gather enough workers and divide them into several batches of production day and night!" ”

Then Manstein shook Qin Chuan's hand and said, "Captain, you have solved a big problem for us, and now ...... It's time to prepare for the battle plan you're talking about! ”

Manstein is right that operations require not only equipment and men, but also detailed information, such as which places on the Black Sea coast of the Caucasus are suitable for landing and which places are not suitable for landing, which roads can be advanced and which places can be attacked after landing, and so on.

However, none of this seems to be a big deal, because the Germans had Brandenburg troops.

Obviously, Manstein would have used the legendary special forces in the Caucasus in advance.
