E2 is a very ordinary stellar field, with an orange spectrum, and is a K0-type star in the main sequence zone, which does not have the environment to give birth to life. Pen, fun, pavilion www. biquge。 infoBut due to the long-term presence of the pirate fleet, there are already traces of human activity here.

Compared with G2 stars in each habitable star field, K0 stars are weaker than G2 stars such as the Sun or the Sunyang in terms of size, mass, brightness and surface temperature. The radius and quality are good, reaching seven or eight percent of the G2 type, but the brightness is only 40%, which is very dim, quite a kind of scorched hell feeling in the myths and legends of the old times.

According to the classification of stars by human beings, there are seven categories from large to small and from light to dark.

O-type stars are blue stars, huge and extremely bright, which are not in the range of main-sequence stars, and are forbidden areas for human life.

Type B stars are blue-white, located in the upper left corner of the main sequence zone, and the most typical one in the New Asian galaxy is the B5 type stellar blue giant in the BH field. Although the B0 to B4 types above B5 are also in the main sequence zone, they are also forbidden areas for life at the current level of human technology.

The next A and F stars are white and yellowish-white, ranging from A0 to F5, 2.5 to 1.2 times the size of the Sun and 80 to 2.5 times brighter, respectively.

The g-type stars further down are called the cradles of life by humans in the new era, and their data are basically the same as those of the sun in all aspects. The agricultural planets currently owned by mankind are completely in the G0 to G5 star domains, and the G2 star fields have the highest probability of giving birth to habitable planets, including the Sun, the Sky Sun, the New Sun, the American Dream, the Cape of Good Hope, and Kilimanjaro.

The Dijing star field that fell to the UAC is a G3-type star, slightly smaller than the G2-type star, so the ecological conditions of the Dijing are far inferior to the other six habitable planets. In addition, the Star of Europe, formerly known as the Sahara, under the control of the new European Union, and its original capital planet, the agricultural planet Red Sea, located in the new European system, are G1-type star fields, which are simply slightly hotter than the Sun.

Based on this understanding, the interstellar expeditions of various countries in recent years have begun to focus on exploring the star fields where G-type stars are located according to the planetary spectrum, which has led to the discovery of the Xinjing star field in New Asia.

Below the g-type are K- and M-type stars that are becoming smaller and smaller in size, mass, and brightness. Although the M-type field is darker, humans pay more attention to it than the K-type, because it is easier to find rare metal bonanes with high strategic value, such as titanium and zirconium. The K-shaped star field between G and M has been reduced to the point of no one cares, and is basically not explored except for the star field located in the main shipping lane.

It is against this backdrop that the E2 star to which the K0 star belongs has become a paradise for pirates to take root.

In the center of the E2 star field, several mining bases have been built on the surface of the second planet, and there are also two space cities in orbit. Among them, the drum-shaped civil space city has a distinct UAC style, which is slender and slender compared to similar space cities in New Asia.

This also confirms the UAC's judgment that supporting the pirate forces will be the disaster of New Asia, otherwise how could the pirate fleet, which lacks the ability to produce and build, build such a large base in such a short period of time.

It can be said that the UAC's support for the pirate fleet has reached the point where there is no concealment, and even the exterior armor of the Space City is painted in the blue that UAC prefers instead of the yellow-green of the New African style. It can be seen that this space city was built by the UAC Federation directly from its own occupied area in the New Asian system, rather than simple technical support.

On the other hand, New Africa did not yet have the ability to build capital ships when it was destroyed, but in the pirate fleet moored outside the counterclockwise air port of this space city, several main order star capital ships appeared, which could only be sold to them by UAC or simply provided for free.

In the bridge of the MGAS-00 ship, the command of the Mobile Force looked at the long-range footage of the pirate base, and they were all indignant at the unscrupulous UAC.

"According to the information we have, the pirate fleet should have 5 main order-class capital ships, and at this time there are only 3 at the airport, so there should be some troops out and about. In addition, the pirate fleet has a total of 55 destroyers of the Cape, Kilimanjaro and Sahara. Except that the number of capital ships is slightly inferior to ours, the overall size of the fleet is basically the same as ours. Xu Yuanxing, the chief of staff who has been promoted to brigadier general, said, "According to the number of warships moored at the airport, only three-fifths of the current pirate fleet is stationed in the E2 star field, and our strength is superior. ”

In addition to the civilian space city built by the UAC at L4 Lagrange, there is also a relatively rudimentary yellow-green semi-fortress space city at L5. The space city was apparently built by the pirate fleet itself at a later stage, and two semi-finished Sahara-class warships were being built in the semi-open dockyard. In other words, the pirate fleet has the capacity to produce warships, and in time it will be further expanded.

Half of the pirate fleet remaining in E2 is stationed at L4 and the other half at L5. However, the distance between the two space cities is only 600 light seconds, and the battleship only needs one ultra-short curvature flight to reach, which is almost negligible in the vast space space.

From a strategic point of view, the semi-fortress space city built by the pirate fleet itself has the capacity to produce warships and should be listed as a priority target. And the civilian space city that UAC helped build is the living quarters of the pirates, which can be dealt with later.

The distance from the inner side of the Kuiper Belt in the E2 field to the orbit of the second planet is about 30 astronomical units, or 240 light minutes. In other words, the image of the pirate base captured by the fleet's optical sensors at this time is four hours ago, and four hours later, the pirate fleet will also see the mobile fleet entering the E2 star field in turn.

E2 is a young stellar field, which also leads to a large number of meteorites that have not been caught by the planets in the star field, just like the Dt3 star field, the advance base of the Space Force, which is basically unable to fly with curvature at will in the star field. Only when you enter the range within the orbit of the third planet can you have a relatively clean airspace.

In this way, there is basically no possibility of a sneak attack by the mobile army, and it can only honestly advance head-on. And all they could do now was to get as close to the second planet as possible by the four hours that the pirate fleet could not see them.
