The rise of nanometers

San Francisco International Airport.

And dozens of large airports on the west coast of North America, not only civil aviation airports, but also military airports, have all entered a state of emergency at this time.

The American soldiers who took over the San Francisco International Airport looked at the flashing dots on the radar and reported to the leader, Colonel Chogori:

"Colonel, 15 large transport planes will land in 24 minutes."

Chogori looked at his watch and found that these planes were traveling very fast, cruising at a speed of 1.7 times the speed of sound.

After taking a deep breath, he adjusted his military uniform, waved his hand and shouted, "Follow me to greet you."

"yes."

Due to the topography and wind direction, there is less volcanic ash that reaches California, and even much less than that that reaches Western California.

But everyone still consciously put on gas masks. After all, in the current situation, many inland cities in North America have lost social order, and many medical supplies production factories have also been paralyzed or captured by escapees.

If there is a physical problem now, it may not be treated in time because there are not enough medical resources.

Twenty-three minutes later, 15 large Kunpeng transport planes arrived at San Francisco International Airport one after another.

After the tail hatch of the transport plane was opened, there were fully armed mechanized infantry, as well as a large number of unmanned multi-legged mechas.

Colonel Khogori looked at the mechanized infantry in front of him with a complicated expression. He did not expect that the Noah Society would end in this way.

However, he did not forget his mission and quickly stepped forward to identify himself: "Report, I am the former colonel of the US Army, Andrew Senchogori, and I have been ordered to guide you."

Colonel Gao Lieyan, who was in charge of the first group of expeditionary forces to land in America, replied to the other party: "Colonel Gao Lieyan, who is the first group of the expeditionary force, please take me to the conference room!"

"OK!"

Except for two platoons of the 750 expeditionary force soldiers, who were responsible for integrating the American troops at the airport, the rest quickly entered San Francisco with the drone regiment.

at the same time.

The person in charge of the Intelligence Department in San Francisco also quickly contacted Gao Lieyan to discuss the current situation.

In the conference room.

Gao Lieyan looked at the American terrain on the sand table with a solemn expression. The Dapeng ground-effect transport aircraft flying at full strength will probably arrive at the west coast of the Americas tomorrow evening.

This time, the federal government deployed a total of 60 Dapeng ground-effect transport aircraft, which can transport 120,000 tons of materials to the Americas at one time. The materials are all rapid settling agents.

Judging from the current eruption of the Yellowstone volcano, the three regions of Wyoming, Idaho, and Montana have been devastated beyond recognition by magma surges, volcanic ash, and toxic gases, and have basically lost the value of rescue.

Gao Lieyan drew three circles on the topographic map with Huangshi Volcano as the center, namely a 100-kilometer radius area, a 200-kilometer radius area, and a 600-kilometer radius area.

Preparing to establish three lines of defense, the Federation is currently unable to do anything about the magma surge, but the volcanic ash and toxic gas can still be suppressed.

General McCarron, who came from a nearby military base, heard Gao Lieyan's plan and asked hesitantly: "Gao, can such a large-scale volcanic ash really be suppressed within the restricted area?"

"The efficiency of rapid settling agents is that one ton of settling agents can settle 5 to 20 tons of volcanic ash. Tomorrow evening, 120,000 tons of settling agents supported by the mainland will arrive in the Americas."

5～20?

McCarron quickly looked through the eruption data of the Yellowstone volcano.

Except for the four large-scale eruptions, which will spew millions of tons of volcanic ash into the atmosphere in a short period of time, the average amount of volcanic ash ejected by small-scale eruptions in other time periods is about 100,000 to 300,000 tons per hour.

The effect of rapid settling agents is mainly related to the concentration of volcanic ash. When volcanic ash has just entered the atmosphere, the volcanic ash is still crowded in an area.

At this stage, the effect of the rapid settling agent will be maximized. On average, each ton of settling agent can settle about 20 tons of volcanic ash.

120,000 tons of settling agent can settle approximately 2.4 million tons of volcanic ash.

In this way, as long as the Yellowstone volcano no longer erupts on a large scale, small-scale eruptions and volcanic ash can still be suppressed.

Seeing McCarron showing a slight smile, Gao Lieyan directly poured cold water on him:

"Don't be too happy too early. The geological activity in the magma lake under the Yellowstone volcano is still very intense. The possibility of a large-scale eruption still exists, and there is another problem."

McCarron, who calmed down again, frowned: "Another question?"

"How did 120,000 tons of sedimentation agent get into the vicinity of the Yellowstone Volcano? If a fighter jet was used to launch rockets, how could 120,000 tons of rockets be launched into the airspace around the Yellowstone Volcano in one day?"

"Gulu!" McCarron suddenly felt helpless.

Gao Lieyan continued: "The mainland has modified 10 ground-effect transport aircraft, which can alleviate the pressure, but we must open a channel as soon as possible and establish a base on the front line."

Hearing this, McCarron looked at the map around the Yellowstone volcano and quickly found a suitable location for the current line base.

"High, the southeastern corner of Washington state is more suitable here."

Looking at the location pointed out by McAllen, it was the southeastern corner of Washington state. There were two small cities there. The city with a more suitable terrain was the city of Lewiston, which was located in the river valley plain.

There is also a medium-sized civil aviation company in Lewiston, and there are also two underground bases. After temporary renovation, they should be able to park Dapeng ground-effect transport aircraft.

Moreover, Lewiston is just 540 kilometers northwest of the Yellowstone Volcano and is in the upwind area of ​​the westerly circulation and northerly winds, so the amount of volcanic ash floating here is relatively small.

Although it is in the middle reaches of the Snake River, the magma tide from the Yellowstone volcano is now mainly concentrated in the upper valley plain of the Snake River.

If the magma tide from the Yellowstone volcano reaches the city of Lewiston, it will have to travel a long distance of about 473 kilometers through the river valley. It will be safe in a short period of time.

Gao Lieyan made a decision immediately: "Okay, let's set up the frontline base in Lewiston."

With the cooperation of the Noah Association and the American Army, the airport in Lewiston was quickly upgraded. Fortunately, although the Dapeng ground-effect transport aircraft is large, it can take off and land vertically. The requirements for the airport are not too high, as long as there are enough Just cement floor.

At noon the next day, the Yellowstone volcano erupted again with moderate intensity. Within an hour, about 830,000 tons of volcanic ash was sent into the stratosphere and troposphere.

at the same time.

The military airport originally belonging to the US Army, as well as a large number of transport aircraft and fighter jets, were also quickly put into use.

The transport aircraft is preparing to transfer the next settling agent; the fighter jets are equipped with rocket launchers and are preparing to cooperate with the Dapeng ground-effect transport aircraft to perform volcanic ash control tasks.

Only by cutting off the Yellowstone Volcano's continued flow of volcanic ash into the atmosphere from its source can this crisis be fundamentally resolved.

Otherwise, the Federation can only ensure that its surrounding areas are not affected. As for other areas, just wish yourself luck!

After the Yellowstone volcano is cut off from transporting volcanic ash into the atmosphere, the volcanic ash already floating in the atmosphere will not be replenished and can be removed bit by bit.

That evening, the west coast of America was dark.

Waves of powerful engine roars came from the distance. This was the Federation's unique detonation rocket engine.

Apparently the first batch of ground-effect transport aircraft successfully crossed the Pacific Ocean and reached thousands of miles away.
