MacArthur's fleet closed the exit of minefields, while the fixed wormholes were near-eternal and could not be closed by manpower. Pen ~ fun ~ pavilion www.biquge.info

However, humans have been operating fixed wormholes between galaxies for more than 100 years and have rich management experience. In order to deal with this special situation of unilateral "closure" of wormholes, there is a set of international conventions.

A red commuter ship followed the last ships to the New African system before the passage was closed, replacing the orange commuter ship normally sent out as a signal ship for the final formation. When the red commuter ship arrives on the other side of the New African Galaxy, it will fly in a circle around the wormhole, acting like a red light to prevent the ships on that side from entering the wormhole, as a way to tell the other side that the Milky Way has unilaterally closed the wormhole.

Then wait until this side of the galaxy sends the orange commuter ship over again to inform you that the wormhole on the other side has been reopened. At this time, the red commuter ship will be the first to enter the wormhole as a ship to open the way, returning to the galaxy. The ships of the New African System followed, and the wormhole resumed normal operations.

Just five minutes after the red commuter boat entered the wormhole, the "Tempest" finally successfully arrived at the secret passage opened up by Fengyu.

Because of the time relationship, Fengyu only found a through-line with the smallest density of space machine mines according to the system's calculations, and discharged almost 100 mines within a diameter of 20 kilometers. Therefore, this passage is extremely narrow, and the "Tempest" must drive straight in the center of the circle, and if it deviates by more than one kilometer, it is possible to detonate a nearby space mine.

Fortunately, this straight line has been pre-stored in the main system, and Luo Yunxi only needs to set up automatic driving, which is safer than human driving. However, if you want to drive autonomously, the "Tempest" cannot be optically invisible, and the main system needs to compare the distribution of minefields to fly.

Therefore, after recovering the "Storm", which was also in a state of optical invisibility, Luo Yunxi ordered to withdraw from optical invisibility and only keep the R particle shield.

At this time, the merits of Moranti's chiseling plan were undoubtedly revealed, even if the "Tempest" dispersed the R particles and re-revealed its figure in front of everyone, but MacArthur's fleet, which was 20,000 kilometers away, was helpless.

At this distance, it doesn't really matter whether the "Tempest" is invisible or not. Even if the battleships of MacArthur's fleet can accurately aim at targets 20,000 kilometers away, the particle beams fired by the battleship's main guns have already diverged to a diameter of 40 meters, and a large amount of energy escapes as the distance increases.

According to the statistics of the tests conducted by various shipyards, the lethality of the battleship's particle beam main gun within 2,000 kilometers can be regarded as the maximum, and there is almost eighty percent of the power within 5,000 kilometers. At 10,000 kilometers, the power is rapidly reduced by half, and at 20,000 kilometers it is only one-tenth of the original.

Therefore, before mobile suits became the absolute main force in space warfare, the fleets of the two warring sides usually controlled the distance within 5,000 kilometers and fired at each other with more than 80% power.

It is only because of the rise of mobile suits that the current situation of the array has changed dramatically, and the fleets of both sides will maintain a distance of at least 5,000 kilometers from the mobile array to avoid a large number of losses in battleships after the defense line of the mobile troops is breached. As a result, the actual distance of the fleets of both sides often exceeded 10,000 kilometers, and the effectiveness of naval artillery fire was greatly reduced.

And as the fourth-generation MS of UAC begins to mass-produce and change clothes, and stream-of-consciousness ace pilots like Fengyu show off their power on the battlefield, countries are continuing to widen the distance. At present, on the frontal battlefield between the new European Union and the UAC in the New African Galaxy, the distance between the fleets of the two sides is almost 15,000 kilometers, and the main guns of the warships are about to be reduced to decorations. Only when the fleet decides to retreat, the divergence generated by the ultra-long-range fire of the main gun can be used to form a large area of coverage, so as to block the pursuit of the opponent's mobile suits.

The development of particle beam weapons has basically reached the point where it is impossible to sustain in this era. The emission of particle beams when flying long distances is unavoidable and has nothing to do with the weapon being launched, but is produced by various disturbances such as celestial gravity, cosmic rays, dark matter consumption, etc.

It's like a beam of light diverges in the atmosphere, the difference is that the atmosphere only needs a few kilometers for a beam of light or particles to diverge to a powerless level, whereas in the open space this process takes tens of thousands of kilometers.

If you want to ensure that the particle beam weapon is still lethal at a distance of tens of thousands of kilometers, you can only continue to increase the caliber of the main gun, such as UAC's new America-class mothership, whose 2000mm main gun is 6.25 times more powerful than the destroyer's 800mm main gun, and can hit 60% of the destroyer's power at a distance of 20,000 kilometers.

However, it doesn't make much sense. The deep-pocketed UAC only has three New America-class motherships, and it is also spread across three star systems, so it cannot form a cluster effect. Although a single mothership can fire a powerful shot at 20,000 kilometers, in terms of consumption speed, it is not comparable to the replenishment speed of the R particle shield, so it is meaningless.

In order to solve the dilemma of the declining warships, countries have begun to develop the electron cannon as the next generation of warship main guns.

However, in terms of the current situation, the "Tempest", which is 20,000 kilometers away from MacArthur's fleet, does not care at all about the salvo of the opponent's main guns, and even if all 50 battleships are hit, a single round of fire will not be able to knock off 50% of the energy of the R-particle shield. A minute later, when MacArthur was ready for the second round of firing, the "Tempest" would have already entered the minefield, and relying on the protection of the space mines, the battleship's main guns would not even have a chance to reach its position, but would instead become a minesweeper.

In fact, the first salvo of MacArthur's fleet hit only three shots, knocked out about 2% of the shield strength of the "Tempest", and it took only a dozen seconds to make up for it.

So under the watchful eyes of nearly 10,000 ships of Taifei WH, the "Tempest", which had returned strongly, swaggered against the artillery fire of MacArthur's fleet and sailed straight towards the minefield. All those who watched this scene had the same question in their minds, "Is this ship preparing to commit suicide?" ”

A few seconds later, something happened that surprised everyone. The "Tempest" sailed into the minefield unharmed, and none of the space mines were detonated as if they were completely unaware of the destroyer's existence.

At this time, Luo Yunxi simply closed the R particle shield in order to prepare for crossing the wormhole later. Anyway, if the space machine mine is detonated, the R-particle shield will not be able to defend against the damage of those kinetic fragments.

On the MacArthur fleet's side, several captains once again exposed the problem of lack of actual combat experience, and without the order of the fleet commander, they filled up the main gun energy for a second round of shelling.

As a result, I saw that the particle beam flew more than 10,000 kilometers and detonated a large number of space mines, and finally dissipated in space.

"Haha! Is this demining? Some of the onlookers couldn't help but laugh.

At this time, the "Tempest" had already entered the passage in the center of the minefield and quickly drove into the entrance of the wormhole, leaving a stunning memory for everyone who was in Taifei WH that day.
