The plane had flown far away, so far that its trace was no longer visible.
The Wright Brothers' many years of research and effort had finally paid off, and they were, of course, extremely excited. They probably wouldn't return until they had thoroughly enjoyed themselves.
However, the experiment was still ongoing.
The massive rewards for the aircraft researchers completely stunned all the researchers, making them fanatical to the point of near madness.
"Alright, gentlemen, let's proceed with the next experiment!"
At Dutch's command, a group of people excitedly ran to the location of the second experimental product.
The first experiment was the plane; the second was the wireless remote-controlled car.
This thing was invented by Mr. Marko, using a small internal combustion engine combined with his wireless remote sensing technology.
To be honest, this thing was not a high-level invention for Mr. Marko.
His previous steamship had already proven that he possessed quite reliable wireless remote control technology. This so-called wireless remote-controlled car was merely transplanting the control system originally used for the steamship onto a car.
To increase the controllable distance of the wireless remote-controlled car, Mr. Marko also installed a signal transmitting and receiving base station in the car's cargo compartment, thereby increasing the car's remote control range.
Due to the underdeveloped battery technology of this era and the inability to miniaturize internal combustion engines, this wireless remote-controlled car did not seem to have much use.
After all, the existence of the base station meant the car could no longer carry cargo, and although the remote control distance was relatively far, the lack of a camera made long-distance remote control a joke.
The only use it had was as a suicide truck to be driven over and detonated, but Mr. Dutch Van der Linde was an arms magnate. He had no need to go to such great lengths to research this thing for self-detonation; if he wanted an explosion, a cannon shot would suffice.
Therefore, this invention could be said to be tasteless to eat and a pity to discard.
It was somewhat of a white elephant.
But Dutch was still very happy.
"Good, Marko, you've done very well! Damn it, I feel like you've opened up a whole new era! Think about it, gentlemen, although we can only research these large remote-controlled vehicles now, what if we develop remote-controlled planes in the future? What if we can develop remote-controlled bombs? Remote-controlled bombs with wings?
Hahaha, invention lies in creation, gentlemen, I hope you can all unleash your own wisdom to create more colorful creations!"
Marko nodded, agreeing deeply: "Yes, Dutch, I think you're right. In fact, I've been thinking recently about whether we can equip bombs with the flight method of planes, allowing bombs to fly on their own to the desired explosion point. This way, not only will no one be able to resist our weapons, but we can even strike targets from super long distances, effectively reducing our casualties!
Oh, sh*t!, I think this idea is very likely to be realized!"
Listening to Marko's words, Dutch was greatly surprised.
Sh*t! Isn't this a missile? Damn it, Mr. Marko has now become a terrifying warmonger!
Leaving everything else aside, even if he built the worst missile, as long as it was built, Dutch would hit the United States Congress the next second.
The second experimental item, the remote-controlled car, was somewhat unsatisfactory, but understandable.
During this period, Mr. Marko's main attention was focused on engine modifications, which will be discussed later.
Immediately following was the third exhibit: the flat-trajectory howitzer.
The term 'howitzer' was not coined in World War II; in fact, howitzers existed in Italy in the fifteenth century, and the term appeared in Europe in the seventeenth century. The flat-trajectory howitzer researched by these three arms researchers was a modified version of a howitzer.
"Mr. Van der Linde, our flat-trajectory howitzer has a 120mm caliber, generally requires three people to operate, and is expected to have a range of about ten kilometers. Its main targets are Tanks or blockhouses!"
Accompanied by the inventor's speech, a cannon barrel, two to three meters long, resembling a mounted machine gun, appeared before everyone's eyes.
This thing was extremely similar to most howitzers of the World War II era. It was designed with three wheels for easy transport, had two steel plates on the sides to block bullets, could rotate almost 360 degrees without blind spots in a broad sense, and had supports at the rear to resist recoil.
This thing actually exists even now; what Arthur and his team used to fight the Cuban Navy in Chapter Five was a howitzer.
The only difference was the much longer firing range.
Dutch was very pleased with this; it was another divine weapon to sell externally.
Damn it, the warlords of Cuba and Mexico are about to strike it rich again.
Flat-trajectory howitzers, handheld grenade launchers, 20mm large-caliber anti-Tank sniper cannons...
All sorts of imaginative weapons were brought out and tested one by one at the experimental site.
Dutch's demands for them were not high; they could research whatever they wanted, he would cover all the funds, and it didn't matter whether it was useful or not.
So the things these scientists researched were bizarre, with some even specifically designed to counter their comrades' inventions.
For example, one side researched a positional cannon, and the other researched a mobile giant cannon to counter positional cannons.
One side researched a plane, and the other already had mounted anti-aircraft machine guns.
Although experiments showed that this thing was difficult to hit planes with, when laid flat, it was absolutely excellent for Tanks.
Finally, after all the inventions had been reviewed, it was the turn of the last one: the 400mm Venice Giant Cannon.
A cannon barrel over twenty meters long was mounted on a detachable steel framework.
Transporting this thing was a huge hassle. The original idea of the chief designer of the Venice Giant Cannon was to mount it on a battleship as its main gun.
However, due to experimental conditions, this test could only be conducted on land.
This specially made cannon barrel cost Mr. Van der Linde a vast amount of funds, manpower, and resources. If the internal combustion engine structure had not been improved by Mr. Marko, and if some simple heavy-duty machines had not already been produced in the steel factory, perhaps even this cannon barrel alone would have been difficult to manufacture.
The steel consumption for this single cannon barrel was equivalent to that of a Tank.
A single shell was almost the height of a person.
According to theoretical calculations, its effective firing range could reach thirty kilometers, a true beast of war.
But why was it left until last for testing? Because it required over two hundred people to use. Assembly alone required over two hundred people to continuously assemble it here.
Dutch remembered that during World War II, Little Mustache had an 800mm super giant cannon.
The Gustav railway gun.
This thing's barrel alone weighed four hundred tons, one armor-piercing shell weighed seven tons, and its firing rate was up to 14 rounds per day.
Damn it, was this thing really useful? The manpower and resources spent just transporting it to the battlefield were absurdly large. Germany even dispatched two anti-aircraft battalions specifically to protect it.
Its main target when designed was to penetrate concrete bunkers.
And the main purpose of this 400mm Venice Giant Cannon was also to penetrate concrete bunkers!
"Mr. Van der Linde, this is the 400mm Venice Giant Cannon we designed! Our purpose in designing this giant cannon is to penetrate concrete bunkers. We had this idea the first time we saw the dense bunkers outside Lemoyne and New Hanover!
Mr. Van der Linde, although we have many bunkers, the enemy can also build them!
Although we don't have to participate in combat, we are equally uneasy about this, so we designed such a massive giant cannon for targeted strikes against bunkers!
This way, even if the enemy also builds their territory full of bunkers, they still won't be our opponents!"
The Italian scientist said proudly, chest puffed out.
In reality, the fundamental reason they researched this thing was that everyone else was researching anti-Tank cannons, anti-aircraft cannons, anti-Tank cannon anti-artillery, and anti-aircraft cannon anti-artillery.
Seeing that they had nothing to target, they had no choice but to pick Mr. Van der Linde's immovable bunkers to counter.
Dutch's eye twitched slightly, but then he burst out laughing.
"Good, very good! We must use every idea we can, create every bomb, artillery piece, and explosion we can! Anticipate the enemy's thoughts, and then counter them!
Now, let the experiment begin!"
