The Provenance repeatedly observed the airspace where the research ship had disappeared, flew to that airspace, and flew in the direction of the research ship over and over again, but the final result was still in vain, and nothing could be found.

At this point, it was already certain that the ship was missing, and the provenance turned around and returned in the helplessness and disappointment of the mine.

The disappearance of the expedition ship turned into an unsolvable mystery in the archives of the military.

On February 24, 2220, the provenance returned to the blue star after a three-and-a-half-month research mission, at which time the new faster-than-light missile had entered the equipment stage and was officially named the magnetic missile. As the only half-mechanical and semi-biological warship in the whole army, the Seed Source was immediately pulled back to Room 1 for all-round maintenance and transformation.

Ye Fei and his comrades-in-arms took this opportunity to rest for a while.

Due to the unexpected success of the raid on the Atlantean capital planet at the end of 2219, and a rare peace situation between humans and Atlanteans at the beginning of 2220, neither side took the initiative to provoke a fight, and the Republic took advantage of this precious time to carry out drastic modifications, and the combat effectiveness of the whole army reached a new level.

The refit and refitting operation of the whole army will continue until the end of 2220, and the refit and refitting will consume a lot of military production capacity and resources, once again delaying the formation of the Fifth Fleet, and causing the planned Fifth Fleet to be suspended again.

The experimental version of the new missile adopts the traditional metal structure, but the mass production version has made a certain improvement to the body material, and the shell of the missile has been changed to a composite structure of multi-layer polymer materials.

The magnetic missile is launched directly into the speed of light. There is no need to break the speed of light at a normal speed, so the strength requirements for the material can be relaxed. Moreover, the use of polymer composite materials can also save a lot of metal resources.

The officers and men of the front-line troops saw only the surface of the missile. In essence, except for the parts that must be made of metal for the magnetic engine, all other parts of the missile can be replaced by plastic resin or other materials, and all metal parts have been eliminated, and even the shell that wraps the fusion material of the warhead is made of polymer materials.

The proportion of non-metallic materials on the finished products of magnetic missiles is as high as 78 percent, making them the weapons that use the most non-metallic materials in human history.

After using a large number of non-metallic materials, the researchers found that the maximum speed of the magnetic missile exceeded a hundred times the speed of light!

This discovery was so surprising that after careful research and analysis, experts in magnetic engines suddenly realized. It is determined that the increase in the speed of magnetic missiles is directly related to the use of a large number of non-metallic materials.

Metals interfere with magnetic forces, while non-metallic materials rarely interact with magnetic forces, and magnetic engines perform better with less interference.

It's a pity that such a behemoth as a battleship, the main body had to be built using a lot of metal, and this achievement could only be used for missiles.

But it doesn't matter, after all, this discovery has found a new direction for researchers, and there is no need to be blind and lucky.

This discovery had another consequence. That is, the military has always had reservations about the semi-biological warship, and even if the provenance successfully carried out several missions, it did not change the overall attitude of the military leadership.

However, after discovering that the magnetic engine has the potential to improve, the ability of the magnetic dirt is artificially enhanced. The proposal to form a semi-biological flotilla was put on the table of the military's top brass.

Or because of the official service of the magnetic missile, the Republic Expeditionary Force was established for the first time in 2204 and is the main equipment of the fleet, which has gone through countless wars. The light-speed torpedo, which has made great contributions to mankind, has been retired from active service.

A magneto-energy missile smaller in size than a light-speed torpedo, but carrying a low-yield fusion warhead. It is fully capable of replacing the light-speed torpedo with its large size and long launch time.

From now on. The main weapon of the military of the Republic is the magnetic energy missile with a range of about three light minutes, and in addition to the magnetic energy missile, the only missile weapon is the planetary burst bomb.

In the past, directed energy weapons, which were the main weapons, including laser cannons and microwave cannons, have completely become second-line auxiliary weapons, or self-defense weapons. If it weren't for the limited number of magnetic missiles that could be carried in the space inside the warship, the military would be eager to cancel these directed energy weapons and make room to fill them all with magnetic missiles.

Since then, the fighting mode of the Republic's fleet has begun to fully shift to faster-than-light confrontation, which is no less significant than the replacement of cold weapons with hot weapons.

Having a powerful weapon is only the first step, no matter how strong the weapon is, it is useless to miss the enemy.

The effective range of the three-light division far exceeds the capabilities of existing detection equipment, and it is urgent to strengthen the detection capability of warships. To this end, the military has developed a reconnaissance version on the basis of the basic type of magnetic missile.

The reconnaissance type magnetic energy missile is about a quarter longer than the basic type, and its main function is to replace the previous reconnaissance ships, and the compact resonance communication instrument in the guò missile body sends reconnaissance data to the warship, which is a disposable reconnaissance equipment that is discarded after use.

At the same time, for the sake of economy, the design of the new unmanned reconnaissance ship that can be reused has also been finalized, and the length of this kind of ship is only more than 100 meters, and the active warship can be carried in large quantities by means of external armor mounting.

The design of these two types of reconnaissance equipment is finalized thanks to another breakthrough in quantum communication technology, or in other words, mankind has broken through the bottleneck left by the communication technology of mechanical civilization.

In the past, the resonance communication technology could only be realized between two resonance communication devices, so it was necessary to build a communication center with a large number of resonance terminals stored on the base satellite.

However, the new technology can make the resonant source continue to vibrate at a fixed frequency, and two resonant sources with the same frequency can immediately form a quantum entanglement state, so as to achieve instant communication.

The communication devices on the reconnaissance missiles and unmanned reconnaissance ships all use this technology, which temporarily forms a communication state with the warship before departure, and cancels it after the mission is over, so that it is no longer necessary to be like the first generation of resonance communication instruments, once the input energy is interrupted, the resonance source will be out of the quantum entanglement state.

What's even more amazing is that this technology can not only make more than two terminals enter the entangled state at the same time, but also realize multi-party instant communication, which is definitely an epoch-making revolution in the history of human communication.

At this moment, no one has realized that the two technologies represented by magnetic engine technology and new quantum communication technology have made breakthroughs one after another, indicating that another industrial revolution is coming! (To be continued......)
