Northern Islands, Construction Island, Newport Manor, Scientific Research Center.

Mu Feng stood in front of a set of scientific research equipment.

On the holographic projection, there is a half-finished projection of the planet.

The diameter of the planet is about 9,555 kilometers, the circumference of the equator is 60,000 kilometers, and the length of the meridian is about 30,000 kilometers.

It is a marine world, and 90% of the surface is ocean.

The area that has been explored and mapped in detail is shown on the planetary projection.

For the time being, there are only the Western Islands, the IJN Islands, and most of the Northern Islands.

The far north of the Square Islands, which is still an unobserved area, is temporarily filled with gray.

The archipelago spans too much from north to south, and large AWACS planes flying 5,000 kilometers north from Newport still can't see the border, and the island is likely to extend all the way to the North Pole.

And on the ocean, in addition to several routes with a width of hundreds of kilometers that have already been explored, the rest is radiated from land airfields, the search radius area of large AWACS aircraft.

Overall, there are still a lot of unexplored areas on the surface of the planet.

According to the data given by the IJN, the archipelago where the USN is located is roughly filled in the corresponding position of the planet's projection.

It is more than 10,000 kilometers southwest of the Northern Islands, but there is an uncertain mark next to it.

The USN Islands are located about 12,000 kilometers from Newport.

After the ocean carrier goes to sea, it will not take the shortest route to the USN Islands, but will sail all the way to the south, cross the Tropic of Cancer, and go to the equatorial region of the planet.

Xingang is about 6,000 kilometers away from the equator in a straight line, and on the morning of the fourth day of the ocean carrier's voyage, it was still about 1,000 kilometers away from the equator, and the overall speed slowed down.

Liaoning, Yuanwang-7, and Sirius spread out their hulls on the sea surface and began to work, and Liaoning's aircraft maintained data sharing with Yuanwang-7 and Sirius.

Ningshuang, Lanzhou, Taiyuan, and the modified aircraft carriers and battleships with other escorts drove around a range of 100 kilometers, and monitored the bottom of the sea on the 15th and 16th.

The planes on Liaoning's body have been reconfigured, and 32 Shocking carrier-based aircraft and 16 upgraded early warning aircraft have all been released one after another at this time.

The 32 Thriller fighters were divided into two groups, a group of 16 were arranged horizontally, with a distance of 60 kilometers between them, and searched along the equator in the east and west directions.

The 16 AWACS planes were also divided into two groups and followed behind Jinghong.

Cruising at twice the speed of sound, Jinghong explored the path in front to find suitable islands, and after discovering candidate islands, the early warning aircraft followed behind to make targeted detailed observations.

The islands discovered by fighter jets will be marked with a rough outline on the planet projection of Mufeng.

The islands that have been explored in detail will form clearer images and data.

The representatives of the other commands, who had just eaten breakfast, were a little surprised when they looked at the shipwives waiting for the wind in Liaoning, almost collectively dispatched, and all of them went to the sea to unfold the hull.

Everyone subconsciously thought that a large-scale deep sea had been discovered, and that a large-scale battle was about to take place, so they all greeted each other, rubbed their hands and prepared to go out to help.

Seeing this, Yatsen, who remained on the ship, immediately issued a broadcast notice:

"Notice: Don't panic everyone, everything is normal with the mothership, we are not in danger, we are observing the detailed situation in the surrounding waters......"

Everyone breathed a sigh of relief, and then they were all curious, why did they observe this sea?

The heads of several headquarters, including Bismarck, Richelieu, Hood, Guanghui, Veneto, and Akagi, had nothing to do after breakfast, so they got together and found Hulun Lake in the command room of the bridge.

The group sat down around Hulun Lake, and Guanghui first asked curiously:

"Sister Hulun, what is such a big observation? Are there any special creatures in this area? ”

When Hulun Lake sits down, he will habitually approach the table and put the very important part of the front of his body on the table to save energy:

"There are no special creatures in this sea, we are going to find a suitable island near here and build a space experiment base for launching artificial satellites."

When several ship girls heard this, they were all at a loss:

"What is Sputnik? What is it used for? ”

The ship girls of World War II, as weapons of war, only have a basic understanding of the universe and the sky.

They had never heard of Sputnik that reappeared after the war.

Hulun Lake opened his mouth, which is equivalent to popularizing military knowledge with Xiaobai, and suddenly couldn't find a suitable entry point, and finally subconsciously asked Mu Feng for help:

"Uh...... Commander, how do you explain to them about Sputnik, can you help? ”

Mu Feng is at the Xingang Scientific Research Center, looking at the projection of the entire planet.

More than 3,000 kilometers south of the Shuangyue Islands, near the equator, there are signs of several ships, which are ocean-going carriers and Liaoning's fleet.

Hearing Hulun Lake's request for help, Mu Feng nodded and agreed, trying to explain in relatively simple words:

"A satellite is the moon, an artificial satellite, an artificial moon, a naturally occurring moon, with no additional functions, and an artificial moon has the function of a communication antenna.

"Zoom in on the missile, dramatically increase the energy, increase the maximum range, and then use the missile to send the satellite out of the atmosphere as a telecommunications device hanging in the sky.

"As long as it is within the range of the satellite, all the points can communicate directly with each other.

"At least as long as three communication satellites are evenly arranged in the equatorial synchronous orbit, global wireless communication beyond the two poles can be realized.

"Compared with radio, satellite communication is closer to our mobile phone, as long as there is a signal, we can make calls directly, without the need for complex tuning.

"But compared with mobile phones, the range of satellite communication is much larger, which is equivalent to hanging the communication base station in the sky, no longer affected by the terrain, and the signal covers the entire planet.

"With communication satellites, you can communicate directly whenever and wherever you are."

Ship girls have basic knowledge of physics, the atmosphere, gravity and other information still know, things fly high enough, they will leave the atmosphere, and will not fall again.

But really sending an artificial satellite into the sky and using it as a communication tool, for people of that era, it was still a plot in science fiction, and it belonged to the level of whimsy.

If ordinary local people put forward this idea now, most of them would probably think it was a joke, and most of them would not take it to heart, and the smile would be over.

But this is proposed by Mu Feng, and Mu Feng has already come up with a lot of weapons, equipment, and technologies that are simply miraculous in his opinion.

With such a premise, if Mu Feng wants to build an artificial satellite now, it is likely to succeed.

So after listening to Mu Feng's explanation, the scene was quiet, and several ship girls present subconsciously grew their mouths, thinking that they might be witnessing a miracle again.
