The expeditionary fleet arrived at Jupiter in late January, Earth time, and in addition to summing up the lessons of the expedition, the northern capital was also facing an even greater challenge - the alien fleet was about to arrive on Earth at the end of February!

In view of the fact that near-earth defense operations may lead to heavy losses on the earth and the moon, the northern capital made a strategic decision to take the initiative to attack and annihilate the enemy in foreign areas, and the northern capital immediately carried out strategic arrangements, and the national aerospace-related departmental units, the northern Yuezhou and the newly established Beiyuezhou fleet were fully mobilized.

In addition to stepping up its own mobilization, Beidu also informed the base group of the situation and asked the base group to cooperate.

In the nearly one year since the expeditionary fleet set out, the Earth and the Moon have changed a lot.

On the earth, the human war against the giant insect has entered its fifth year, through various military and biochemical means, although human beings still do not see the hope of annihilating the giant insect, but also fully stabilize the battle line between humans and insects, global agricultural and industrial production has entered a period of recovery, and countries are brewing counteroffensive plans.

The focus of Beidu and the base group continues to be on the moon, and the Beiyuezhou base has made great progress in this year, whether it is mining capacity, smelting capacity or manufacturing capacity, it is the largest industrial and agricultural base on the moon and the mainstay of the human space program.

The international base has also undergone a lot of changes, its scale and strength in all aspects are more than a year ago in the Beiyuezhou base, the orbital factory belonging to the base group began to manufacture space warships as early as a few months ago, the first batch of 12 warships off the assembly line not long ago, has completed sea trials, and officially formed the international space fleet.

The international fleet has 12 capital ships and more than 30 auxiliary warships, and its main warships belong to the same class as the 024 class, with a displacement of about 6,000 tons.

At this time, the Beiyuezhou Fleet had more than 100 ships of the improved 011 class, more than 30 ships of the improved 024 class, and eight ships of the 026 class with a displacement of 7,700 tons, and its overall combat capability was four to six times that of the international fleet.

This is a very interesting phenomenon, because the international fleet, which can represent the majority of countries, is not as strong as the Beiyuezhou fleet, which represents China's interests, and the US-led Al Qaeda group is deeply indignant but helpless.

In addition, the Beiyuezhou base also has an aviation unit composed of a large number of air-space fighters, which is responsible for the defense of Beiyuezhou; the outside world is not yet clear about the specific number and establishment of this unit, but it is only known that this unit has a very earthy code name -- Ringing Arrow.

In addition, there are long-range missile bases, heavy laser cannon positions, and thousands of nuclear warheads in reserve.

No matter how you look at it, relying on the moon to resist the alien fleet is the safest plan, so the international fleet is not interested in China's combat plan.

But this is not something that the international fleet is willing or not, the strength of Beiyuezhou and the alien fleet is not a joke, the northern capital is backed by the Beiyuezhou base, and it is the most powerful national government in the world.

Since the Beiyuezhou Fleet asked the international fleet to cooperate in the operation, even if the Yankees were reluctant, the Al Qaeda group could only pinch its nose and admit it.

Taking 10,000 steps back, the alien fleet is not only threatening the Chinese side, but also the reluctance of the international fleet, and more importantly, it does not want to be commanded by the Beiyuezhou fleet.

The two sides agreed that the establishment of a joint fleet would only be in response to the invasion of the alien fleet, and that the combined fleet would be disbanded on the spot after the end of the campaign.

During the establishment of the Joint Fleet, the International Fleet was placed under the command of the Beiyuezhou Fleet, but the commander of the Combined Fleet had the right to refuse unreasonable combat orders, and whether the orders were reasonable or whether they fell within the scope of refusal was not something that could be decided by the parties concerned.

Of course, both the Northern Capital and the Al Qaeda group know that when they really reach that point, it is also justified by the public, and the mother-in-law is justified, and unless it is a major event that affects the outcome of the battle, it is possible to conduct a real trial investigation.

After a series of preparations, the Combined Fleet was formed in mid-February, and after a short tactical run-in between the two sides, the fleet set off on 18 February.

The fleet uses the gravitational slingshot effect of the Earth to accelerate and fly in the direction of the alien fleet.

On 26 February, the Combined Fleet, which had more than 230 large and small warships, encountered an alien fleet at a distance of about 200,000 kilometers from Earth.

At this time, the alien fleet has entered a state of deceleration due to its proximity to the earth, but the relative speed of the two sides is still as high as hundreds of kilometers per second, and the fighters are fleeting.

When the distance between the two sides was still more than 3,000 kilometers in a straight line, the combined fleet launched a large number of missiles, and the missile group met the alien fleet at a speed more than twice that of the fleet.

At the same time, the combined fleet was firing at full power, and various artillery pieces smashed armor-piercing shells of various calibers at alien warships.

The improved missile has extremely strong tracking capabilities, and after the radar locks on to the target, the missile does not hesitate to crash into the alien warship, and detonates the nuclear warhead in advance at the moment of contact, and the void in front of the combined fleet suddenly explodes into a dazzling nuclear light.

The Combined Fleet has spent a lot of money, the number of missiles is ten times as many as that of alien warships, and the missiles have taken all kinds of hidden measures, only half of them are in the appearance of missiles, and the other half are disguised as various irregular small celestial bodies, and they are painted pure black, and they try every means to camouflage.

Although the alien fleet launched a large number of fine lights to intercept them, the number of missiles was too large, and more than 200 missiles exploded, blowing up one-third of the enemy ships on the spot.

This result was a surprise to both the enemy and the enemy, and the combined fleet immediately replenished a batch of missiles.

Before the explosion was over, the rest of the alien warships rushed through the nuclear explosion zone at a very high speed, just in time to hit the head-on shells.

Although the shells are very ordinary, they can't stand the relative speed of the two sides, think about it, what is the concept of shells smashing on alien warships at a speed of more than 100 kilometers per second?

As a result, the 20 mm shells smashed out by the 1020 rapid-fire cannon can cause extremely heavy damage to the alien battleship, and the cannonball with a slightly larger caliber can easily penetrate the armor of the alien battleship, and if it is a shell of more than 100 mm, it is not a problem to destroy half of the enemy ships.

However, to everyone's surprise, the survivability of the alien battleship is extremely strong, even if half of the battleship is damaged in the battle, it still fights to the death, and what is even more amazing is that as long as it does not hurt the stern, the speed of the alien battleship can always remain unslowed, and it will always follow the friendly forces closely, and it will never fall behind.
