Chapter 1128 High-speed evacuation operation (1)

Li Chengxi actually doesn't like to use missiles. After all, in a world without missiles, it's simply a dimensionality reduction attack.

But even if we don't like to use them, we have to have them. It would be uncomfortable if we don't have them when we really need them.

Alyssa looked through the viewfinder at the sky dyed red by the explosion. She didn't even have the energy to be surprised. After all, since she met Li Chengxi, there have been too many things that tore her worldview.

The Swan flew higher and higher under the propulsion of the booster rocket, but because the floating engine could not stand the Swan upright, unlike the conventional rocket that went up vertically, the Swan went up diagonally.

As the decision speed exceeded, the shock waves at the front of the Swan's solid ram gradually overlapped, and eventually became a heat barrier emitting strong red light. The intense air friction caused the bridge to automatically turn on the light-shielding mode to protect the eyes of the members in the bridge.

At this speed, the aircraft in the atmosphere could not catch up, and as the vibration in the bridge gradually decreased, the red flashes caused by air friction began to slowly decrease, and the sky gradually became thinner, successfully reaching the edge of the atmosphere.

"Reach the turning point in ten seconds."

"Turn off the booster rocket."

The rocket engine gradually extinguished, and the Swan now relied on the main engine and inertia to maintain its speed and began to adjust its flight attitude.

"Attitude adjustment completed."

"Turning point passed."

"Circularize orbit."

"Understood, circularize orbit."

Although it has now broken through the atmosphere and returned to the microgravity environment in the bridge, the Swan has not escaped the constraints of the planet's gravity.

The flight trajectory of the Swan is now actually a parabola, which will fly a circle and then fall back to the planet.

At this time, the orbit needs to be circularized.

Similar to the fact that artificial satellites will not fall in the sky, accelerating in a specific direction at the gravity turning point can turn the parabola into a circle around the planet.

This is the low-Earth orbit, and this is how everything from artificial satellites to space stations enter orbit.

The booster rocket has little fuel left, and it will completely shut down after burning for about thirty seconds. With a slight explosion, the booster rocket is abandoned, and the orbit continues to be circularized by the power of the Swan.

It is expected that the orbit will be circularized in five minutes, and then gravity navigation or pulse flight can be directly started to escape the constraints of this planet.

This is also the reason why Alyssa doesn't like to go to the planet. It's too troublesome to escape the constraints of gravity.

"The shadow of the ship appeared on the radar, right in front of our route, and entered the visual range."

After hearing An Yun's report, Alyssa called up the viewfinder and soon saw a "big basket" floating in the low-Earth orbit.

That is actually an orbital bomber. Its appearance is different from that of ordinary warships. It looks like an inverted basket. The bombs in the shape of "javelin" are hung under the basket. When it is necessary to bomb somewhere, just launch the javelin.

This kind of ship with extreme specialization is actually very fragile. Considering the working environment of the orbital bomber, there will be several light cruisers nearby to escort it.

This is because the light cruiser is flexible enough. If it is replaced by other larger ships, it may be pulled down by the gravity of the planet and eventually burn in the atmosphere.

The radar of the Swan discovered the target in orbit, and the other party must have discovered the Swan.

About three light cruisers sailed out from the black cosmic background, and it was obvious that they were in combat mode.

Alyssa didn't want to get entangled with them, but these guys just happened to block the route. The Swan was now at a critical moment of circularization and could not turn at will.

Then she had to rush.

Just as she was about to announce the entry into combat mode, Alyssa suddenly remembered that there were still many civilians on the ship this time, so she picked up the microphone:

"This is Captain Alyssa of the Swan. This ship is about to enter combat mode and shut down all unnecessary energy supplies."

This felt a bit like the captain of a plane. Then the lights in the bridge of the Swan turned red, and all anti-aircraft guns were pushed out of the gun positions by hydraulic presses and began to run the self-check program.

Soldiers who had received gunnery training also ran to the anti-aircraft gun control room and sat in the gun positions on standby at any time.

"Main gun charging."

"Understood, the main gun began to charge."

The sturdy ram of the Swan opened up and down, revealing a huge black muzzle, and the arc began to gather.

Then, the main gun aimed at the orbital bomber and fired a test shot.

Since it is in low-Earth orbit, even ion beams will be slightly bent by gravity, especially when firing at long distances. It can be said that the more accurate the aim, the more crooked the shot.

A test shot from the main gun flew under the orbital bomber and did not hit the target at all.

The good news is that the shells fired back by the other side were similar.

But the Swan has an advantage. Its shipboard computer is the most advanced model.

This is one of the many devices replaced by the royalists for the Swan. I heard that due to the high manufacturing cost, it will be difficult to be practical for at least the next ten years.

The shipboard computer of a general ship will recalculate the trajectory after firing a test shot, and then make fine adjustments based on the experience of the gunner.

There is no problem with this mode, but general shipboard computers will not consider the influence of other factors.

For example, gravity.

So you can see that the three light cruisers fired back several shots, but they still couldn't even touch the edge of the Swan, even if the Swan did not change its course at all.

On the other hand, the Swan's onboard computer also takes into account the parameters of gravity's impact on trajectory into its calculations, so one test shot is enough to calibrate all shooting parameters.

As the main gun of the Swan was recharged, the huge spear-shaped beam accurately hit the side of the orbital bomber. The opponent's ship, which looked like an inverted basket or a brush, was not suitable for direct confrontation. The shield flashed for a moment and was then penetrated by the light spear cannon. The entire ship broke into two sections within a dozen seconds and fell into the atmosphere.

The remaining three light cruisers did not expect the Swan to be so accurate, and they did not expect the power of the light spear cannon to far exceed that of ordinary light cruisers. As the Swan was approaching quickly, they did not bother to recalibrate the shooting parameters on the shipboard computer, and relied entirely on the experience of the gunner to provide firepower coverage.

This operation seemed reckless, but it was actually correct. If it was still carried out according to the combat manual, I am afraid that they would be named by the Swan one by one and turned into space garbage.

One beam after another flew past the edge of the Swan, but there were also shells and ion beams falling on the front of the Swan. For a while, the flash of the shield and the flash of the ion beam or shell explosion made it almost impossible for the naked eye to observe the outside through the glass of the bridge.

However, the optical aiming system was not affected by this, and Long still fired back calmly.

This was a direct confrontation, there was no such thing as tactics, it was a competition of skills and courage.

The fragments of the shells would pass through the shield and hit the armor plate like raindrops, and there was always a sound of heavy rain in the bridge.

Alyssa stared at the screen showing the ship data of the Swan, and the shield energy was decreasing at a speed visible to the naked eye.

At this time, good news came.

"Orbit circularization is completed."

"Start pulse flight!"

"Understood, pulse flight preparation"

The engine at the tail of the Swan began to flash violently, and the engine light began to become intermittent. Three seconds later, the more than 300-meter-long Swan seemed to be stretched into a thin line and disappeared from the low-Earth orbit.
