Homo sapiens.

Through the magnetic field radar, Kavo saw that the ships had arrived at the designated positions, so he picked up the walkie-talkie: "All are heading towards New Granada at full speed."

"receive."

These airships all adopt electric propellers as the main propulsion method, and the auxiliary jet engines are only used as auxiliary power for emergency acceleration and maneuvering.

After all, the airship is powered by nuclear reactors, coupled with the use of a two-stage composite thermoelectric conversion system, the power is very sufficient.

Therefore, the use of electric propellers is the kingly way. If jet engines are used, tens of thousands of tons of light fuel will be used, which will seriously squeeze the payload of the airship.

At a cruising speed of 250 kilometers per hour, the aerospace fleet flew towards New Granada, 1.5 kilometers away, and is expected to arrive at the west coast of New Granada in 60 hours.

……

Northeast of Kangaroo Country.

Cape York Air Force Base.

This is a mechanism for the U.S. military to use the free association to jointly form an air force base here, which is currently affiliated to the free association and is numbered A-06 base.

At this time, in the Cape York Air Force Base, long-wave radar has detected UFOs in the sky over New Guinea.

The base chief, Major General Rhodes, hurried to the radar monitoring room.

"Is the target still above East Irian?"

Smith, the head of the radar monitoring room, quickly replied: "They are moving, they are moving eastward, and the speed is 250 kilometers per hour."

"Can you adjust the satellite to check?"

Smith looked at the trajectory of the satellite: "In about 12 minutes, a keyhole satellite will pass over the western Pacific Ocean."

The current U.S. military has long lost the calmness it used to have. After dozens of professional satellites were killed by Homo sapiens, the spy satellites in low-Earth orbit are now stretched.

Despite the urgent replenishment of 12 keyhole satellites through the Space Exploration Corporation, the monitoring power in low-Earth orbit has not yet returned to its peak period.

12 minutes later.

The keyhole satellite finally moved over the western Pacific Ocean, and Smith quickly aimed the camera at the area where the UFO was found.

Soon they saw the true face of the UFO.

"Airship?" Chief of Staff Allen, who had just arrived, murmured subconsciously.

However, Smith, who was staring at the screen, had a look of shock on his face: "3.3 kilometers long? Is this really an airship?"

Allen, who came back to his senses, paid more attention to the deck of the airship in the picture. At first he thought it was a solar panel, but he didn't realize that it was the flight deck until he saw a dozen fighter jets parked on it.

He swallowed his throat: "Gulu...is this an aerospace carrier?"

Major General Rhodes frowned, his expression became more serious: "It seems that this is the new equipment launched by Homo sapiens?"

They actually knew that Homo sapiens had built a lot of airships before.

After all, hundreds of sperm whale-class transport airships have been produced, plus dozens of communication airships. These things are flying around in the sky. America's intelligence agencies are not blind, and they must have collected some information.

It's just that in their previous intelligence, those airships were not used in the military field, and their size was not so exaggerated.

Seeing that the expressions of the two became serious, Allen said with a smile, "Major General Rhodes, this kind of big airship is a target, and it can be shot down with just one missile, so there is no need to worry too much."

Rhodes looked confused, as if he was looking at a fool, and thought to himself: "You country bumpkins are really arrogant, and you are still the chief of staff, and you don't even know that Homo sapiens has gamma ray weapons." '

"Ahem...Colonel Allen, have you read the relevant evaluation report of Homo sapiens?"

Allen was at a loss: "What report?"

Shet!Rhodes has made up his mind that after a while, he must find a way to get this guy to go back to Canberra to train recruits.

He suppressed his anger: "It's the document sent by the Pentagon last Friday."

"Uh... sorry, I just came back from vacation yesterday, so I haven't had time to watch it yet." Allen scratched his head awkwardly.

Falk squid!With these idiots, can America really defeat Homo sapiens?A sense of frustration involuntarily emerged in Rhodes' heart.

Smith on the side was also speechless. He explained helplessly: "Homo sapiens has a gamma-ray weapon that can intercept aircraft missiles and even destroy satellites in low-Earth orbit."

"Oh Maikar... It's really scary that they have such a weapon." Allen was shocked.

In fact, this is also the news that the Pentagon blocked the destruction of satellites, using the solar storm as an excuse to say that some satellites were attacked by the solar storm.

After all, this kind of thing is a shame for America.

If it is announced, the morale blow to the free association will be too serious.

That's why Allen, the chief of staff who had just been transferred from the Australian Army, didn't know about gamma rays.

After listening to Smith's explanation, Allen will be very surprised.

After Homo sapiens possessed gamma-ray weapons, the U.S. military had to reassess the combat power of Homo sapiens.

This is also the reason why Major General Rhodes's expression is so solemn, because their missiles and fighters have no way to approach these airships.

He quickly reported the incident to the Pentagon.

Chapter 441 I'm at a loss

America.

California, one of the new Pentagons, is located in a small town.

After receiving an emergency report from the Cape York Air Force Base in the Kangaroo Country, Victor immediately paid attention to it.

He immediately found a dozen intelligence analysts: "Immediately analyze this intelligence, and then write a targeted assessment report."

A group of intelligence analysts took the file.

"What? A giant airship three kilometers long?"

"Are you kidding? This thing is a target..."

"John, you underestimate Homo sapiens. Don't forget that they have gamma-ray weapons."

While discussing, these intelligence analysts thought about how to deal with this airship.

However, after racking their brains for a long time, they still didn't think of many solutions.

The only feasible solutions at present are laser cannons and microwave weapons.

But as intelligence analysts of the Pentagon, they are very familiar with the performance of their own weapons and equipment.

The laser cannons and microwave cannons currently equipped by the U.S. military have a hard-kill distance of less than 20 kilometers. Among them, microwave weapons can also be installed on missile warheads to achieve long-distance strikes on targets.

The problem is the effective range.

There is no way to directly attack the airship of Homo sapiens within 20 kilometers.

Indirect attacks require the use of missiles, but missiles also cannot approach Homo sapiens airships.

What's more, whether it is a laser cannon or a microwave cannon at this stage, the power is an obvious problem. Even if it is within this range, whether it can work in the face of a huge airship is really a question that needs to be discussed.

After all, Lucia has launched a vehicle-mounted laser cannon before, which claims to be able to hit targets within 10 kilometers, but this target actually refers to small drones or people.

As for the XX laser cannon that is boasted on the Internet, it claims that it can be launched from the ground to directly destroy satellites in low-Earth orbit, which can indeed be done.

The problem is that the destruction method of this laser cannon is different from the imaginary direct burning. Instead, the laser destroys its sensors and makes the satellite lose its effect. It does not really blow up the satellite.

This is a typical soft kill.

The effect of soft killing on large targets is not ideal. Not only does it require long-term irradiation, it also needs to ensure good weather and no anti-laser coating on the target surface.

After a group of intelligence analysts simulated, they found that the long-distance soft-kill lasers could not threaten Homo sapiens airships at all.

The reason is very simple. One's side can irradiate Homo sapiens' airships with lasers, and Homo sapiens' airships can also counterattack with death beam cannons.

With the range of the Homo sapiens death beam cannon, the two sides irradiate each other, and there is a high probability that the US military will be cooked first.

After listening to the discussion of a group of intelligence analysts, Victor asked: "If multiple laser cannons are concentrated, can this airship be destroyed?"

An intelligence analyst who specializes in the frontier field of weapons shook his head: "It's very difficult. The power of the current laser cannons is not enough, and the hard-kill distance is within 20 kilometers. We have no way to get dozens of laser cannons to the opponent's 20 kilometers. within."

"After all, the opponent's flight altitude is 25 kilometers above sea level, plus the angle problem, it is basically impossible to approach the opponent within 20 kilometers." Another intelligence analyst added.

Victor was a little reconciled: "Why can Homo sapiens use a high-power gamma ray cannon, can't we imitate it?"

"I have communicated with several weapons developers before, we do have the ability to produce gamma ray cannons, but..."

"But what?" Victor demanded.

The intelligence analyst spread his hands: "The cost is very high, not only the production cost, but also the maintenance cost."

"Cost? If mass-produced, the cost should be reduced?" Victor asked.

However, the intelligence analyst smiled wryly and continued to shake his head:

"The most suitable material for a gamma ray exciter is cobalt-60. However, the production conditions of this product are very harsh, and the risk is very high. In case of misoperation or poor storage, you will understand the consequences."

"Cobalt 60?" Victor had naturally heard of this great poison.

"In addition, the half-life of cobalt-60 is only more than five years, which means that the excitation core must be replaced regularly. This is what I call maintenance costs. Even if it is not used after manufacture, the gamma rays from the excitation core will continue to be released."

Victor was completely devastated.

Unless cobalt 60 can be produced at a low cost, according to the current annual production of several hundred grams in America, it is estimated that if the cobalt 60 itself decays completely, it may not be able to equip a high-power gamma ray cannon.

After all, among Homo sapiens’ death ray cannons, the smallest type of death ray cannon requires 0.5 tons of cobalt-60; while the largest type of death ray cannon requires 5 tons of cobalt 60.

This is due to the amount of cobalt 60, which forcibly enhances the power and range of the dead light cannon.

Without sufficient resources, there is no way for America to imitate.

Victor asked again: "Can electromagnetic guns be used?"

"The range of the electromagnetic gun is too short, and a dozen kilometers is basically the limit."

Another short-legged player.

However, another intelligence analyst still provided an idea: "If the electromagnetic gun can be installed in low-Earth orbit, it may be possible to use the acceleration of gravity to increase the effective range of the electromagnetic gun."

"Naive idea, Homo sapiens can easily attack satellites in low earth orbit, how do you ensure the safety of electromagnetic gun satellites?"

"Also, have you considered the satellite's power supply and the recoil of the railgun?"

As they spoke, the crowd started to quarrel again.

Faced with this kind of quarrel, Victor was not interested in participating, so he left quickly and went to Eduardo's office to report the situation.

Edward also received relevant information.

"For Homo sapiens' airship, what countermeasures does the intelligence analysis department have?"

Victor smiled wryly and shook his head: "They are still arguing. There is no good solution for the time being. The only feasible way is to equip some long-range laser cannons to destroy the airship's electronic equipment and sensors."

"..." Edward has a very headache. Since he took over the Pentagon, he feels that his hair has fallen a lot. If this continues, he may become bald.

Victor said another analysis conclusion: "In addition, judging from the direction of the opponent's flight, it is very likely that this airship fleet will be deployed in the New Granada area. We need to increase military investment in Latin America."

However, Edward looked helpless: "Victor, we have no money."

"How is it possible? Didn't 2500 billion be approved in the second quarter? How could there be no money?"

Edward explained: "Do you think that 2500 billion can be used casually? Now we have to strengthen the military base in the Free Association, which accounts for a large part of the funds."

"In addition, we will need a lot of money to restore the retired aircraft carriers and warships that have been sealed up before, and put them back into the active combat order."

"and also……"

After hearing Edward's complaints, Victor complained a little speechlessly: "Can you stop buying those coffee machines that cost tens of thousands of dollars?"

Obviously Victor knew about the extravagance and corruption within the US military.

Now that the front line is so critical, it is really hard for him to accept that these guys are still unrepentant.

But Edward waved his hand: "Victor, our US military has its own special situation. It is difficult for me to change this problem. If it is forcibly compressed, it may lead to a mutiny."

It's not like he doesn't know the internal problems of the US military, but he himself is one of the vested interests, so how could he cut off his own money.

Unless he wanted to kill himself with seven shots in the back.

Chapter 442 A Difficult Choice

The Second Aerospace Fleet is advancing at full speed.

Speed ​​through the thin air of the stratosphere.

In addition to America's discovery of this aerospace fleet, other forces with surveillance satellites also quickly discovered its existence.
