The Interstellar Frontier Fortress, similar to the Stonefish Fortress, is the frontier of Homo sapiens.

At any time, you may encounter an uninvited guest from afar.

Therefore, Zhang Yucai wanted to improve the weapons and equipment of the fortress as soon as possible, after all, as a military facility, the Stonefish Fortress could not play its existential significance if it did not have weapons and equipment.

After receiving Zhang Yu's order, Wu Muquan immediately mobilized some resources and began to produce weapons and equipment.

The first thing to be produced is a wave-absorbing space mine, which can absorb most of the electromagnetic waves and prevent the mine from being detected by electromagnetic radar, and its core is equipped with a 300,000-ton yield neutron bomb.

The reason why a neutron bomb is used instead of a pure hydrogen bomb is naturally because the lethality of the hydrogen bomb in a vacuum environment is limited, and it is not as useful as a dense stream of high-energy neutrons.

At least neutrons are not something that ordinary first-class civilizations can resist, especially dense high-energy neutrons.

Even if it cannot directly kill the others, it can seriously interfere with the communication and detection systems of the other party, and damage some peripheral instruments and equipment.

Of course, Ebony Springs does not expect space mines to be able to deal with all enemies.

If the other side has technologies such as magnetic field detection, gravitational wave detection, neutrino detection, etc., then space mines will have basically no effect.

To a certain extent, after entering the first-level civilization, due to the development of detection technology and the limitation of the speed of light, the war between the first-level civilizations will return to the mode of "queuing up to shoot", "naval artillery bombardment", and "hand-to-hand combat".

It is very difficult for one first-level civilization to sneak up on another first-level civilization.

For example, Homo sapiens plans to sneak attack the native of the six-clawed civilization, and that is because Homo sapiens has obvious advantages in many technologies.

As long as the six-clawed civilization masters the gravitational wave detection technology or neutrino detection technology, the expeditionary fleet of Homo sapiens may be discovered within a radius of 0.5~1 light years near the six-clawed giant.

Of course, it cannot be ruled out that the six-claw civilization was negligent and did not guard against the invasion of external forces; Or simply no gravitational wave and neutrino detection technology.

Even without gravitational wave and neutrino detection technology, the warning radius can reach about 0.01 light years by relying on pure electromagnetic wave detection technology.

It's just a distance of 0.01 light years, which is too close for a first-level civilization, and it is basically the rhythm of being output by the face.

There is no way, in the first-level civilization stage, each first-level civilization is actually very embarrassing.

There is no way for the speed of the spacecraft to break through the speed of light, and the detection means are at most the speed of light, and the means of attack are also severely limited.

Similar to Homo sapiens, there are very few first-class civilizations with long-distance and delay-free communication technology.

At the beginning, Li Qingye analyzed the intelligent machine civilization civilization, but destroyed 39 first-level civilizations and swallowed the technology of these civilizations, but including the intelligent machine civilization, did not master the long-distance and delay-free communication technology.

It can be seen that the long-distance non-delay communication technology owned by Homo sapiens is also rare among the first-class civilizations.

Navigation speed, communication speed, detection speed, and attack speed are all limited by the speed of light.

In the event of a war, the only way to do this was to use the classical era tactics of lining up and shooting, or the tactics of hand-to-hand combat.

As for launching missiles and the like, on the interstellar battlefield, it is actually equivalent to two people holding pistols and firing at each other.

After all, no matter how fast the missile is, can it be faster than electromagnetic waves, gravitational waves, neutrinos, and magnetic fields?

And the first-level civilization has more or less mastered laser weapons, even if there are no mature laser weapons, they can also use nuclear explosion interception technology.

This is the helplessness of interstellar warfare.

When the scale of both sides is stretched to the level of astronomical units, it is difficult for ambushes, encirclements, traps, etc. to work for the time being.

As for the aliens in the European and American blockbusters, those are all brain-dead stars, which does not conform to the logic of normal aliens' behavior at all.

Wouldn't it be nice for aliens who can cross the galaxy to reach the solar system, if they really want to deal with human civilization, they won't land on the earth at all and attack directly in outer space?

What?

You say aliens can't bear to cooperate with the living planet? In order to facilitate colonization in the future, the landing method was adopted?

Joke, the ecological environment that aliens need is different from that of humans, so why do you think that aliens will protect the ecological environment of the earth?

For example, the Homo sapiens expeditionary fleet, which planned to attack the six-clawed superstar, did not have any plans for a landing operation, and its first phase of tactics was to wash the floor and burn the glass.

First completely exterminating the indigenous civilization, and then transforming the captured planets into an environment suitable for their own race, is the main means for alien civilizations to enter other planetary systems.

This is actually very similar to the method used by the Europa people to colonize the whole world in the first place.

Homo sapiens would not be brain-dead enough to use planet landing to attack a civilization.

Unless the level of civilization of the other side is lower than that of the first-class civilization, there is no possibility of landing operations.

Due to the various limitations of interstellar warfare, the weaponry of Stonefish Fortress also needs to adapt to these limitations.

For example, the recently developed Super Magnetic Field Shield, which can withstand most non-laser weapons.

Even a very close nuclear explosion can weaken the lethality of a nuclear explosion.

However, the current production capacity of the super magnetic field generator is very small.

So far, only 2 experimental warships have been equipped.

The reason why the production capacity is so small is because of the core raw material of the super magnetic field generator - double neutron material.

That's right, the core raw material of the super magnetic field generator is the double neutron material, and the magnetic field generator made from this thing produces a magnetic field that is 160,000 times stronger than the previous conventional superconducting coil.

This thing can produce a magnetic field similar to that of a neutron star.

With such a terrible magnetic field strength, even the gravitational field can be distorted to a certain extent.

Once the Super Magnetic Shield is activated, there is no way to penetrate the Super Magnetic Shield with a weapon with mass at this stage.

The super magnetic field generated by the dual-neutron material can not only be used as a shield, but also as a magnetic field acceleration for the plasma thruster, further increasing the plasma jet speed.

Of course, the plasma thruster can be transformed into a high-energy particle cannon, and the principle is the same.

Dual-neutron materials are indeed a good thing.

However, the production capacity is pitifully low.

At present, Homo sapiens' 8 double neutron manufacturing plants can only produce 3.4~3.6 kg of double neutron materials per year.

And the production of a small set of super magnetic field generators, which requires at least 0.8 kg of double neutron materials, plus the needs of other scientific research institutions, there is simply no way to equip Stonefish Fortress with such a good thing.
