The fourteen interstellar cannons were taken care of, although several interstellar cannons had been destroyed before, but the captains who were afraid that they would not be completely destroyed still poured a large amount of firepower into the interstellar cannons, and almost dug out a big hole where the interstellar cannons were located, so as to let go of the interstellar cannons that were completely gone.

Ten minutes later, all the military facilities that could be found were destroyed, and because of the storage of the force field, at least a third of the laser deviated from the target, and no one could say exactly where it hit in the end, anyway, there was no loss of civilian facilities and houses, and the city was in chaos.

Ye Fei was happy to mention this in his heart, the last time he attacked YM174 was two and a half years ago, and at that time, in order to stimulate the Atlanteans without people, the intensity of the fleet's ground attack was very limited.

This time, there were no more original concerns, and the unscrupulous surprise attack brought Ye Fei and the officers and men of the whole fleet a sense of revenge.

Jiang Yufei suddenly said with emotion: "The technology of the Atlanteans is so much stronger than ours, and without a fleet, it is like being beaten and not being able to get started, this air supremacy, no matter how powerful the race is, you can't do without it." ”

"Haha, you're still dragging it?" Ye Feipi moved the muscles on his face without smiling.

The airborne landing was about to begin, and at this time he was really not in the mood to joke, although he pretended to be relaxed on the surface, he was very nervous in his heart.

Jiang Yufei tilted his head and said, "It's just that I suddenly feel quite touched, someone used to say that the truth is within the range of the cannon." Now I finally understand that not only is the truth of our humans within the range of the cannons, but the truth of the Atlanteans is the same. ”

"Come on, I'll talk to you about these things when I'm free." Ye Fei interrupted Jiang Yufei's feelings, "Ruan Peng, inform the black bear, you can start." ”

"Yes!" Nguyen Peng immediately transferred the order to the commandos.

The commandos had already gathered on their respective assault ships, and there was silence in the preparation cabin.

Receiving the order, the black bear turned on the commando's public channel: "Attention all, board the plane!" ”

Sixty-seven commandos rushed to their mechs at the same time, quickly burrowing into them. A large combat weapon with a height of 4.5 meters twists and kicks. Begin your pre-departure warm-up.

"Brothers, everyone knows the mission this time, I won't say more, I just want to tell you a word. The first one with my surname Ren landed and the last one left. The rest of the brothers watched it. "There is nothing grandiose about the mobilization of the black bears. It's so straightforward that you can't help but laugh.

But this is the scene, and no commando can laugh, not even if he calls all the members of the team brothers—the commandos are mixed with men and women. Even if he deploys the right personnel for the commando team when he is on the base star, he has not forgotten the principle of matching men and women.

However, the army in war is the most gender-blurring place, where there are only comrades-in-arms, only soldiers, no men and women.

"Bear Boss, everyone knows what kind of person you are, and we can trust you as a person." One of the fighters said without hesitation.

"Thank you!" The black bear thanked him sincerely, and then his tone suddenly changed, "Are you all ready?" ”

"A large team is ready!"

"The second team is good!"

"The three teams are fine!"

"All four teams are on standby!

"Let's go!" At the Black Bear's order, the four assault ships pulled out the air in the cabin at the same time, the thick airtight door slowly opened, and the flying mechs of the four brigades jumped out of the battleship one after another, forming a diagonal flight formation while deforming.

Sixty-seven flying mechs flew directly to YM174, and Ye Fei, who witnessed this qiē, first silently prayed that the soldiers could return safely, and then ordered loudly: "The whole fleet - fire cover!" ”

Forty-six battleships once again activated their electromagnetic cannons and gravity guns, and the rain of fire that fell from the sky once again enveloped YM174, and forty-seven flying mechs led by black bears avoided the sky above the city and flew to the left side of the planet, plunging headlong into the atmosphere.

This position allows you to avoid your own covering fire, as well as the remaining anti-aircraft fire in the city.

The surface of the fighter plane that crashed into the atmosphere was shrouded in a layer of red scorching fire, and the thick heat insulation coating on the surface of the fighter quickly volatilized at high temperatures, taking away a large amount of heat while thinning at a speed visible to the naked eye.

Although the flying mecha was designed with an advanced aerodynamic shape, the resistance of the air still caused the descent to decrease rapidly, and after entering the stratosphere, the speed of the fighter has been reduced to Mach 2, and the heat of friction with the air is not enough to produce red heat.

Mach is double the speed of sound, because the speed of sound in the atmosphere is affected by various factors such as air pressure, altitude and air temperature, so the speed of the aircraft at different altitudes and different temperatures when breaking through the speed of sound is also different, so when calculating the speed of the aircraft, the ground velocity is usually not used to calculate, but the Mach number is used to express.

In other words, the current speed of the flying mecha cannot reach 680 meters per second, which is 4560 meters per second.

Immediately after that, the formation plunged headlong into the force field, and the speed dropped sharply, and there was a tendency to get slower and slower, just like the shells that fell into the force field.

"Black bear, how's it going?" Ye Fei asked worriedly.

"It's okay, it's not much except that speed has an effect." The black bear scolded indignantly, "Damn, it's not like flying in the atmosphere at all. ”

"What does that look like?" Ye Fei asked in surprise.

"It's like getting into the paste, and I feel like a worm stuck to a spider's web." The black bear tried to fly a 360-degree roll, and what would have taken only one second to complete took a full five seconds to complete, which was literally slowing down the camera.

The flying mecha is like an extension of the commando's body, and all external situations can be selectively fed back to the team members through the sense of touch, such as the high temperature when they have just entered the atmosphere, and when it is fed back to the tactile sense of the commando, only the feeling of dryness is left, not the high temperature that can directly burn people into charcoal.

"Try level flight, collect a little bit of jù first, you can use it as a reference for a while." Ye Fei pretended to be calm and said.

"Wolf cub, try to level it." Black Bear commanded.

"Roger!" The wolf cub's mind flashed, the flaps of the flying mecha deflected, and the fighter plane immediately began to flatten.

Don't look at the fighter plane piloted by the commandos flying decently, but in fact, after a few months of learning, the commandos' overall flying skills are still rotten.

Flying is a systematic science, and for several months, the theory is not enough. (To be continued......)
