Everything is ready, and the next step is to ignite and launch.

The conventional launch method can only ensure the accuracy within the range, and this time the ultra-long range has extremely high requirements for accuracy, and the time and direction of free flight determine the final hit rate of the missile.

In order to improve accuracy, Ye Han had to give up the previous conventional launch method, and instead used a manipulator to send the missile outside the ship, first accompanied the battleship for a short distance, and only after there was no problem with the general direction, did he ignite the missile to accelerate.

The acceleration phase of the missile was only a few minutes, and by the time the acceleration phase was over, the missile was already far in front of the Thunder Mountain.

This is only the first stage of the launch, and then, every once in a while, the Leishan will check the direction of the missile, and as soon as the slightest deviation is found, the fire control system will immediately fine-tune the direction of the missile to ensure that the missile remains in the correct flight direction.

In this way, this missile, which pinned the hopes of the whole ship, flew towards the alien fleet...... Of course, it's only the first one.

With the experience of renovating the first one, the subsequent renovations went very smoothly, and seven hours later, two more missiles passed the test and were launched by the Leishan one after another.

In this way, in the four days before and after, the Leishan fired a total of 11 long-range missiles at enemy ships.

The transformation of long-range missiles is still continuing, but there are only so many long-range missiles on the ship, and I don't know if the ones that have been launched can hit the target.

Not only is Ye Han looking forward to the performance of this batch of missiles, from Gao Kai, who is close to Nanzhou, to the high-level people who are far away in Beiyuezhou, they all have the same expectations as him.

Time passed day by day in waiting and restlessness, the Leishan had to observe the missiles and the enemy every day, and seeing that it was about to hit the target in two more days, Ye Han suddenly discovered that the enemy ship had released a batch of alien fighters, and they were old alien fighters.

Ye Han, who received the news, immediately rushed to the bridge, and immediately asked after seeing the alien fighter on the screen: "What direction is the enemy plane?" ”

"It's our direction, it should be coming for us." He Lu said.

Ye Han immediately became alert: "Put the plane at this time, they want to intercept the missile?" ”

The distance of the Leishan is still far away, and the range of the alien fighter is very limited, and the possibility of targeting the Leishan is very small, so the enemy's target can only be missiles.

Luo Qi was stunned: "Impossible, right?" It's so fast, how can you stop it? ”

At present, the relative speed between the Thunder Mountain and the alien fleet is about 70 kilometers per second, and the speed of the missiles is even faster, and the relative speed of the enemy ships is more than 100 kilometers per second.

Not to mention the pitiful firepower of the alien fighters, even if they are replaced by alien warships with strong firepower, it is not so easy to intercept the missiles in such a short time.

Ye Han also couldn't figure it out, and said hesitantly: "It shouldn't be able to stop...... No, they didn't want to use fighters to block missiles, did they? ”

When everyone heard this, they all pricked up their ears, and Luo Qi nodded his head: "Maybe, most likely, aliens are not inferior to these planes." Is there a way to avoid it? ”

He Lu shook his head with a calm face, but immediately nodded again.

Luo Qi's whole person was not good: "You are nodding and shaking your head, what do you mean?" ”

"It should be, but I still have to think about it." He Lu said.

Luo Qi urged: "What do you think, say it and listen to it, don't think about it yourself." ”

He Lu said with a smile: "Let's activate the missile in advance, control the missile to maneuver a few seconds in advance, as long as it deviates a little, we can drill past the enemy plane, and it will be almost the same if we turn around and correct the direction...... It's ......"

"What's it?"

"It's just that the distance is too far, and the activation and evasion time is not easy to master." He Lu said with a frown.

After a week's continuous flight, the distance between the first missile and the Leishan was half a light minute, and the control signal was one minute back and forth.

This is only the current time delay, the distance between the missile and the warship is still growing, that is, the time delay is still growing, plus the speed of the enemy aircraft is difficult to determine, and it is not certain exactly when and at what distance it will encounter.

And the control signal can't have a half-spread pool, and even a delay of just one second may be wasted.

Ye Han said: "Then calculate and prepare in advance, and the system will send signals regularly to minimize the risk." ”

"That's all it can be." He Lu said.

Determine the response plan, the next step is a long-term monitoring calculation, this is a very monotonous and boring work, as long as the speed of the enemy aircraft changes slightly, the encounter time will change greatly, the result is that all the data must be recalculated, the signal transmission time must also be reformulated.

Luo Qi simply didn't understand this aspect of work, Ye Han understood but was not so proficient, only He Lu was competent for this work, so He Lu took up this heavy burden without giving in, and found a few bridge officers who were proficient in orbit calculations to form a temporary monitoring group to monitor and calculate 24 hours a day, and all the data must be calculated independently by three people, and then compare the calculation results to ensure that there are no problems with the calculation results to the greatest extent.

In this way, the temporary monitoring team rotated for two days in a row, and finally ushered in a critical moment.

Everyone rushed to the bridge in advance and waited nervously for the missile to meet the enemy aircraft.

Thirty-two seconds before the encounter, the Leishan automatically sent out a control signal, and half a minute later, the first missile started its engine and suddenly began to change direction.

The unprepared enemy planes hurriedly opened fire, and the light passed by the missiles, which passed the enemy planes in the blink of an eye.

The news of the success of the air defense was transmitted back to the Thunder Mountain, and everyone breathed a sigh of relief.

Ye Han concluded: "This tactic is very good, He Lu, you and the monitoring team work hard, and hold on for a few more days." ”

"Yes, don't worry." He Lu immediately agreed, and immediately put into the next round of calculations.

The second and third missiles will encounter the enemy aircraft seven hours later, and the monitoring team will have to calculate all the data before the encounter.

In fact, the data are all ready-made, and I am afraid that the enemy aircraft will change speed during this time.

However, the situation changed more complicated than expected, and only about 20 minutes later, the monitoring team found that the alien fleet sent a second team of alien fighters.

This group of enemy planes must have been the first missile to successfully penetrate the defense, and the situation ahead was not optimistic, so Ye Hangang put down a little bit of his heart and raised it again.

Seven hours later, the second wave of missiles encountered enemy aircraft, and the monitoring group made all preparations in advance, and the alien aircraft group dispersed in advance.

The signal was sent out on time, and everyone waited anxiously for the final result, and a minute later, a blinding glare suddenly burst on the main screen.
