It doesn't even need to be a warship, for example, as long as a piece of ice floe in the Arctic Ocean, plus a power system, is bulldozed on it, it is a good aircraft carrier platform.

The United States has no shortage of aircraft, and the current P-51 Mustang is also being manufactured on a large scale, and what the United States lacks is an aircraft carrier, which is a necessary platform for naval warfare.

However, the ideal is very full, and the reality is cruel.

Although the ice cube has those advantages just now, the disadvantages are also obvious, and the strength of the ice cube is not high.

The climatic conditions in the Atlantic Ocean are very harsh, and the ice in the Atlantic Ocean will be knocked down by a wave at any time, turning into two halves, then three halves, and four halves, so it is impossible to use it to make aircraft carriers.

Roosevelt gave up, but Jeffrey didn't give up, and now, he came to report to President Roosevelt, of course, to find a solution to the problem.

To increase the strength of the ice, it is necessary to change the internal structure of the ice.

Jeffrey was followed by two famous American scientists, Walter Hohenstein and Hermann Mark.

"Mr. President, after our research, we found that the ice cubes made by adding cotton and fiber to fresh water have good mechanical properties and high strength, which fully meet the needs of aircraft carrier construction." "We can guarantee that it can withstand the winds and waves of the Atlantic," Walter said. ”

"How are you going to prove it?" President Roosevelt asked.

His eyes were on a wooden box brought by the other party, at this time, Herman was slowly opening the wooden box, inside the box, there were still layers of quilts, when opened, you could see a stream of white gas coming out of it.

In fact, it is not that it comes out of the inside, but because it is relatively cold inside, so when it is opened, the outside air is liquefied, forming white gas, which is the same as the white gas breathed out in winter.

When they were opened, two ice cubes were revealed, one of which was plain ice, clear and transparent, while the other was a frozen cloudy substance, which looked somewhat like frozen cheese.

"Can we do an experiment for you on the spot, forgive us for our rudeness, and ask your guards to shoot at it?" Jeffrey asked.

If you want to prove that something is hard or not, shooting it is the easiest way.

"Okay, let's go to the garden outside." Roosevelt said.

Shoot here, it's not appropriate.

So, Jeffrey pushed Roosevelt in a wheelchair, and Walter and Herman each held a piece of ice, and left the room and went out into the open space in the garden.

Their actions attracted the attention of many people, and when they came to the garden, Marshall and others also came to see them.

"You can't use a pistol, change to a rifle." Marshall puffed on his cigarette and shouted to the captain of the guard.

So, Roosevelt's captain of the guard changed into a standard rifle and stood about fifty meters from the ice, ready to shoot.

Roosevelt was in a wheelchair, looking at it with expectation, and the small ice cube pinned too much hope on him.

"Bang!" The gunshot rang out, and as the shot rang out, a bullet spun and hit the little block of ice, and then the ice immediately scattered in all directions, splattering everywhere.

The crystal clear ice turned into crushed ice chips and bloomed into a beautiful little flower.

This is an ordinary ice cube with no mechanical strength and almost shatters at the touch of it.

The captain of the guard slowly turned the muzzle of the gun and aimed at the second block, which was the main thing. Everyone's eyes were on the ice cube of the same size and thickness, staring at the ice cube that was muddy because it was full of impurities.

"Bang!" A second shot rang out, and as flames erupted from the muzzle, bullets flew onto the ice.

I saw that the ice cube was pushed back for a while, and at the same time, the bullet was actually bounced away.

This thing, which is actually harder than steel, actually bounced bullets away!

"Ouch!" At this time, Marshall roared loudly, and he bowed his head nervously, his military cap, which had flown to the side.

After the bullet was bounced off just now, it actually rushed towards him, and the wise Marshall, an important aide under Roosevelt, almost went to see God in advance because of this accident.

Marshall retracted his head, really frightened, just now, the bullet hit his hat, and it also brought a lot of impact to his head, and sweat swished out of his back.

However, when he saw that everyone was looking at him, Marshall immediately relieved, he couldn't be embarrassed in front of so many people!

So, Marshall bent down, picked up his hat, patted the dirt, and put it back on his head, but there were already two bullet holes left on it, which looked very funny.

Marshall strode forward, in front of the ice, to divert everyone's attention and focus on the key project.

"Well, this ice cube is hard enough." Marshall looked at the front of the ice, and under the impact of the bullet, it left a shallow crater, and it can even be said that this pit was not knocked out, but should have melted the heat generated by the impact of the bullet.

This strength is definitely high enough, and it is not inferior to steel plates of the same thickness.

"We put special cotton and fibers in it, but we have also done other experiments, and if we want to further reduce costs, we can just add the most ordinary sawdust, as long as we build it in a cold area and freeze it overnight." Jeffrey said it easily, from now on, the United States no longer has to worry about the number of warships is not enough, they have the simplest and most economical scheme.

"Let's go, let's go to the office." Roosevelt's eyes were no longer as excited as they had just now, and at this time, his brows were a little furrowed, as if he had thought of something.

Sure enough, when he returned to the office, Roosevelt spoke again: "Our first problem has been overcome, the ice has enough strength to be used as a material for building aircraft carriers, but we still have a new problem, it has to melt when the temperature is high, how can we overcome this problem?" ”

When you build in a cold area, you don't have to think about how to freeze it into ice, for example, in Canada, there are many cold lakes, where you can make it directly from the local fresh water.

However, it is not only to fight in the alpine regions, it is to fight in the Atlantic, how to ensure that such a battleship does not melt in the sun?

If the mighty fleet goes out and melts in the middle of the battle, it will definitely become a joke for the whole world.

Roosevelt's concerns were warranted.
