In the nuclear bomb, Yang Yifei will only use neutron bombs and hydrogen bombs, and he basically does not consider atomic bombs and three-phase bombs, because the nuclear contamination of these two nuclear bombs is too serious.

Neutron bombs, more formally known as highly radiological weapons, have weakened blast wave effects, increased radiation, kill only enemy personnel, cause little damage to buildings and facilities, and do not bring long-term radioactive contamination.

This is also the reason why Raccoon City was able to re-enter so quickly after being bombarded by neutrons.

The killing principle of the neutron bomb is to use the strong penetration of neutrons, the nucleus composed of protons and neutrons, its protons are positively charged, neutrons are not charged, and the neutrons are not charged after being launched from the nucleus, and the penetration is extremely strong.

Within the radius of destruction, neutrons can penetrate the steel armor of the tank and the thick walls of reinforced concrete buildings, killing and injuring those in it.

When neutrons pass through the human body, the molecules and atoms in the human body deteriorate or turn into charged ions, causing nuclear reactions of carbon, hydrogen and nitrogen atoms in the human body and destroying cell tissues.

The 2,000-ton yield neutron bomb has a direct kill radius of about 1 km, and the chickens and dogs are not left within 1 km and are turned into ashes.

The neutron bomb only weakened the blast wave effect, not at all, and the shock wave at the center of the explosion was still very strong.

The effective killing radius is 3 to 4 kilometers, and the shock wave in this range is no longer very powerful, relying on neutron radiation to kill people, and those who are passed through the body by neutrons, even if they do not die immediately, will die of radiation sickness after a day to a month.

The area of Ambrera's army aviation base is almost exactly this range, so Yang Yifei will use this equivalent, which can just cover the entire base, and will not spread outward, and even affect the biochemical research base less than 16 kilometers away.

Kevin had already entered the control station of the launch vehicle, and the Tomahawk cruise missiles with nuclear warheads installed by the rocketeers had also been loaded into the launcher on the launcher.

The infantry had all entered the armored vehicles and were ready to be deployed, and the moment the missiles were sent out, it was time for them to set off.

The company was still on its way back to the company with jet fuel in a tanker truck loaded with aviation kerosene, and the base was to be guarded by them.

Claire's team, except for Claire herself, who strongly requested to participate in the battle, and computer expert McGee assisted in the radar car, everyone else stayed at the base.

"Coordinates locked, longitude -116.212848 degrees W, latitude 37.043292 degrees north latitude......"

The strike accuracy of the Tomahawk missile is very high, and the maximum error does not exceed 30 meters, which is basically no error for the three or four kilometers of the killing radius of the nuclear warhead.

What's more, the target distance is only more than 140 kilometers, and the coordinates can be accurate to 6 decimal places, which basically refers to where to hit.

"The lock is complete, you can fire at any time, boss, come on one last moment!" After Kevin made the preliminary preparations, he turned his head and grinned at Yang Yifei.

"Okay." Yang Yifei was also excited, now as long as he gently pressed the ignition button, a nuclear bomb will be launched, this feeling of mastering a destructive weapon makes Yang Yifei's heart tremble slightly, this is especially in the past, it is a right that only the president has!

And just now he watched Kevin's operation the whole way, and he has already written down all his operations, and Alice is too, with their current brain strength and learning ability, they will never forget it after watching it once, they are also people who can shoot missiles now.

"Smack"

Yang Yifei's index finger clicked, and then immediately rushed out of the control station and looked in the direction of the launch vehicle.

"Snort...... Whew......"

The launch vehicle was 1.6 kilometers away, and only a shocking ignition sound of the rocket thrust device was heard in the distance, and a white pillar dragging a long tail flame quickly rose into the sky, leaving a column of smoke in the air and flying away in the northwest direction.

"It's spectacular, it's spectacular, I don't know how spectacular the explosion is, but unfortunately we can't see it."

Yang Yifei looked up at the pillar of smoke in the sky, sighed, and then ordered loudly: "Everyone get in the car and prepare to go, the No. 1 and No. 2 tanks will open the road in front, and the large army will set off 1 kilometer away from the No. 1 and No. 2 tanks, and report any abnormal situation on the way." ”

“yes sir。”

Yang Yifei is not the kind of arrogant lord, he was nothing when he was in a hurry before, but now that he has entered the combat state, he must always be cautious.

It takes about 8 to 9 minutes for the missile to reach the target location, and the other side is in a state of shutdown, they have no idea that a nuclear bomb is smashing into their heads, and Ambrella's support is doomed, but Isaacs is not without the slightest ability to resist.

When the radar locks on to the target, it will continuously emit radar waves to the target, about once every 1.5 seconds, and the coverage range is about 1 kilometer in diameter, which is equivalent to pointing the way to the missile, which is also the meaning of the word "guide" of the missile.

The lock-on state of the radar may only require a simple operation by the operator, but the frequency of the transmitted radar waves and the scanning state are completely different.

In scanning mode, the radar emits a 360-degree radar wave, which is a scanning capability that covers the full field of view, and is emitted approximately every 13 seconds to monitor the situation within the effective radius.

When an anomalous target is found, it will focus on scanning in that direction, and the frequency of radar wave emission will be accelerated.

In lockdown mode, the radar scans only about 10 degrees, and the frequency of emitted radar waves is shortened from 13 seconds to about 1.5 seconds.

The Wuzhi and fighter planes are equipped with radar wave receiving devices, and when the enemy's radar emits radar waves, their own side can also receive the signal.

Through the frequency of the radar wave, you can judge the working status of the other party, determine whether you have been locked by the radar, so as to respond, and after scanning the flying missile, you can either launch an interceptor missile or evacuate the place.

Even with the support of the database of the advanced radar system, relying on the usual reconnaissance to obtain the opponent's lock signal, record and analyze, it can also distinguish whether the enemy's fire control radar wave is a ground radar or an air lock, and even distinguish the model.

If the radar wave emission frequency is more than 10 seconds, it means that the opponent is in a normal scanning and monitoring state, if it is about 5 seconds, it means that it has been discovered by the enemy, and the enemy radar is in scanning mode while measuring the range, if it is only about 1.5 seconds, it is basically locked by the fire control radar.

The warning system on the Wuzhihe fighter will alert the pilot at the first time, that is, what people see in the movie, the dashboard flashes red, and the alarm sound of "chirp" is issued, and the more advanced ones directly have artificial intelligence voice prompts.

It's a pity that Ambrera's Wuzhi is not turned on now, and the security personnel are still on standby in the barracks, and they never dreamed that in this last days, there are still people who can play cruise missiles, because even among them there is no such talent.

In fact, Ambrera is too careless, their armed forces are basically self-produced, and they are too confident in the T virus, so they don't think about controlling the strategic weapons of those armies.

They chose to use the T virus to destroy the world in order to minimize the harm to the earth, and those strategic weapons are also the first time they want to destroy the world after they complete the annihilation.

They were superstitious about the power of biochemical weapons, but Yang Yifei and his gang took advantage of the loopholes, and mastered these weapons that were enough to destroy them, which can be regarded as a cocoon.
