I have a shelter in the last days

Chapter 306 UFOs

As the only armed spacecraft model in human civilization that has the ability to fly both in the universe and inside the planet, the Iron Spike has a fusion reactor of nearly 4 million kilowatts.This power is four times higher than the total installed capacity of the Three Gorges Hydropower Station, the largest hydropower station in history. The high-strength and high-heat-resistant main armor ensures that it can not only resist the oncoming high-speed particles and small micro-meteorites during high-speed space travel. It can also withstand the friction and high temperature of returning and breaking through the atmosphere.When such armor is faced with kinetic energy weapons, basically it will not cause any damage as long as it is not pierced.

As an armed model, the Iron Spike is equipped with a total of three types of weapons, which are variable-wavelength laser weapons with a power of hundreds of millions of watts. This laser weapon can attack targets thousands of kilometers away in space, and the attack speed is the speed of light. It is almost impossible to dodge, but on the planet because of the curvature of the planet, the attack distance is much shorter; there is also a kinetic energy weapon based on the electromagnetic gun, which can fire at a speed exceeding 30 times the speed of sound even in an atmospheric environment. alloy shells; and explosive weapons based on various explosive bombs including metal hydrogen, fission bombs, fusion bombs, etc. Of course, the carrier of such weapons is still dominated by missiles, although the speed is slower than the first two, But the advantage is that the lethality and damage range are even greater, and because of the atmosphere on the planet, the destructive power of this type of explosive weapon will be transmitted to farther places in the form of shock waves, and its power and damage range will increase exponentially. .

"Attention, attention, the enemy UFO is approaching. It is 276.42 kilometers away from the ship, and the flight speed is 600 kilometers per hour." Allen retrieved the object that was captured by Zhuo Fan from the data fed back by his radar and satellite through the data link. Call it a UFO that is "for nothing".

"Broadcast the message again! See how it responds." Zhuo Fan looked at the positions of the two parties on the holographic screen and decided to give the UFO another chance.

"Strong electromagnetic field activity was detected, but no regular electromagnetic wave signal was received." Alan's voice responded 1 minute later.

"Sure enough, I shouldn't have expected it! It seems that it is going to confront us head-on!" Zhuo Fan curled his lips, and suddenly said loudly: "Alan, prepare your weapons!"

The raised armor on both sides of the Iron Spike in the sky suddenly slid forward, and four thick and short gun barrels protruded from it, two of which were very symmetrical on one side. These were the cannons of two laser cannons and two electromagnetic cannons. Tube.

"This should be our first time fighting an alien high-tech civilization?" Zhuo Fan asked suddenly, staring at the increasingly approaching light spots on the map.

"Will this be recorded in the annals of human civilization?" Zhuo Fan's eyes shone brightly: "Do you think we will be made into film and television works or written as literary works in the future?"

"I think you will be punished by the fleet if you rashly start a war with a high-level civilization..." Evans said resentfully while fastening his seat belt. He almost pulled it on his pants just now...

"Obviously they attacked us first, and they rudely destroyed the drone that was a diplomatic envoy! You must know that drones are also an inseparable part of our human civilization! What's more, as a diplomatic envoy, they were also attacked. This Civilization obviously has no lower limit at all!" Zhuo Fan said nonchalantly with a big wave of his hand.

"I very much agree with the captain's opinion. Not only drones, but also AI is an inseparable part of human civilization!" Spaceship AI Allen spoke in an excited tone: "Captain, the laser weapon is ready."

"emission!"

A green beam of light suddenly appeared at the muzzle of the Iron Spike, and it reached the UFO in an instant. The speed of light attack made it impossible to dodge.

Although the "Chariot of God" was hit by the laser weapon of the Iron Spike, the expected explosion or piercing damage did not appear on the "Chariot of God", but the shock surrounding the "Chariot of God" There was a circle of light blue ripples, and when the laser hit it, it was scattered with a circle of green light arcs.But the "Chariot of God" flew towards the Iron Nail at a constant speed.

"Change the wavelength and frequency!" Zhuo Fan frowned and ordered when he saw the picture on the hologram.

Soon, the color of the laser light changed. The laser light irradiated on the "Chariot of God" changed from green to yellow, then from yellow to red, and finally from red to transparent. The laser generator is used to excite lasers of different wavelengths and frequencies. Finally, the laser turns transparent because the wavelength of the laser has been changed to an infrared band that is invisible to the human eye.

The frequency output characteristics of the laser are determined by the nature of the transition luminescence between the relevant energy levels of the atoms that excite the laser working substance and the structure and properties of the resonant cavity, and the change of color is the reason for the continuous change of the laser wavelength, and different power Lasers with different densities, different output waveforms, and different wavelengths will produce different killing and destructive effects when interacting with different target materials.The reason why Zhuo Fan ordered to change the wavelength and frequency was because he did not know what materials the enemy aircraft used, but it was obvious that the opponent did not seem to be afraid of weapons such as lasers.

"High-energy plasma detected! Attached to the surface of the enemy's flying object." It took only a few seconds for Allen to analyze the means used by the opponent and display them simultaneously in the holographic image.

"This should be a kind of plasma barrier. In some special cases, the plasma will cause laser light to scatter. The general principle is that the localized surface state electromagnetic movement mode of light and free electrons tightly combined can make the light wave travel continuously in it. It is absorbed and gradually attenuated. This aspect is not my research direction. I don’t know the specific implementation principle, but human civilization has also conducted similar plasma defense experiments before. Unfortunately, the energy level of human plasma generators is still a little smaller It cannot be practically applied. If we successfully develop a similar plasma barrier, future spacecraft will not need to wear thick armor. If we want to deal with this plasma barrier, the only way we currently have is to fight with it. The output energy consumption, the energy used to generate plasma can be used up to attack its body, but it seems that our laser weapons may not be effective in a short time." Ding Hao explained in a timely manner .

"Alan, the electromagnetic gun is ready, launch!" Zhuo Fan decisively switched to another attack method when he heard this.

With a "swish", the two metal shells flew out at a speed of more than 30 times the speed of sound under the acceleration of the electromagnetic orbit.Although the gun barrel of the electromagnetic gun protrudes very short, there is still a long electromagnetic track inside the Iron Spike.Because the rail structure is used instead of the coil structure, the shells of the electromagnetic gun are not electrically charged during the launch process, but are charged through the armature, but after the shells fly out of the track, the current is cut off due to the ultra-high current intensity, which will produce a huge Flame, so the metal shells will dissociate and produce plasma after flying out of the muzzle, so that the two shells fly out with a buttock of fire as if there are propellers behind them.
