During the flight, bypassing the ground anti-aircraft fire kill zone, Long Yun climbed into the economic cruising state after crossing the majestic Caucasus Mountains in one breath, and slowly flew back to Stavropol with the remaining fuel in a careful manner.

On the way back, thinking back to the battle just now, Long Yun briefly counted with his fingers, but he couldn't figure out how many enemy planes he had killed: the air defense forces shot down could not be counted, then there should always be five or six in total, so the modification of the White Twenty was basically successful, which made him very happy.

In the next fierce battle, it is better to continue to use the white twenty as a landline.

After the ultra-low-altitude battle of the real yàn nature, Long Yun's return journey can be regarded as a qiēshun lì; Of course, this kind of shun is based on the premise of "mastering the deployment of ground air defense firepower," otherwise, just like he is now, in order to save fuel, he will fly all the way at an altitude of several thousand meters, and even the ground-to-air missiles that are backward in technology can be directly hit.

Moreover, it has to be said that after slipping through the murderous Transcaucasian region at an ultra-low altitude, he has been flying in accordance with the predetermined route formulated and reported before the war, so he was able to calmly pass through the ground-to-air missile fire network of the Territorial Defense Force without gaps; After the fierce battle, it was easy to return home, and now the things to pay attention to have changed from enemy planes to fuel gauges, Long Yun was quite satisfied with the weight loss effect of the white twenty landline, and it seemed that the previous simulation software training was really not in vain.

In this way, until the more advanced Su-27M is received and familiarized, the only remaining white twenty Su-27S can still be of great use; But I don't know who is superior and who is inferior to the Sukhoi fighter after weight loss compared with an opponent like F-15S/MTD?

Long Yun, who had just killed several enemy planes. When he thought of this, he frowned rather trickily. Because he suddenly remembered. Maybe it's because his mind has always been highly concentrated during the battle, and he actually forgot to use his superpowers in the battle just now; Although it is a bit overkill to infiltrate consciousness in a "fishing" battle like today, sooner or later he will encounter Harold Fisher in the air with the "Agile Eagle", and that tough opponent with a tenacious style, why can he not be affected by consciousness infiltration......

In any case, luck is sometimes almost as important as technology in the confrontation between top pilots.

If superpowers don't help. really relied on the performance of the fighter itself to compete with the "shark", although Long Yun was very confident in his skills, but he also did not feel good about himself and thought that "he can win".

But now, I can't take care of this guy for the time being, and there are still many things to do!

Thinking of the upcoming large-scale aerial chaos, Long Yun knew very well that he had a heavy responsibility in this battle, maybe the Americans sent the "shark" for a single purpose, just to deal with themselves, but he Long Yun had a heavy responsibility on his body, and he didn't have time to engage in a one-on-one peak duel with his opponent.

At the previous secret meeting, the battle plan of the Southern Theater Command was obtained. Long Yun still remembers this vividly, now that the "anti-radiation operation" operation is already on the way. Then he is not in a hurry to return to reality, but intends to seriously deal with the next battle in a parallel world. Although he did not plan to launch an anti-radiation missile into the air in this battle in which the R-27P/EP missile would be the protagonist, the battle arrangement for him from above could be said to be exactly what he wanted, and it was also one of the reasons why Long Yun asked Kirilenko to disassemble the equipment on the White No. 20.

Yes, in the sky battlefield where electromagnetic signals are scattered everywhere and anti-radiation missiles are whistling back and forth, what could be safer than a fighter plane with no radar at all?

……

After the attack, he returned from the attack, and in the afternoon of this day, Long Yun met Igor Kirilenko, who was always busy, in the maintenance hangar as usual, and also thanked him.

As for whether the modified white No. 20 Su-27S can be qualified for high-intensity combat missions, an ultra-low-altitude actual combat in the morning has given a powerful answer; However, while being happy, Long Yun was not satisfied, but was thinking about making further changes to the landline.

After all, after the modification according to his plan, the improvement of the maneuverability of the fighter is very obvious, but it also loses the function of the fire control system, judging from today's combat situation, simply let the R-73M's self-homing head intercept the target on its own, sometimes it is not very safe. So he proposed some suggestions for improvement to Kirilenko, which was also approved by the engineers:

"Ah, with regard to the target interception of missiles, you mean to change the panel so that the missile can receive the pilot's target bearing indication? What's this...... Well, I don't think it's a big problem; After all, the front-end instruments and control devices of the cockpit of the fighter are still there, so we quickly come up with a plan, and we can install and debug it soon. ”

"Yes! That's great. ”

The signal control system of the fighter and how to transmit the number to the missile are completely unknown, Kirilenko's reply made Long Yun nod happily, "In short, the interface doesn't need to be too complicated, as long as it can be used to indicate the target direction to the missile through guò trackball or other equipment, whether it can be intercepted and locked, I can grasp this myself." ”

"Grasp ...... yourself?"

It seems to be a very ordinary sentence, but it made Kirilenko squint his eyes suspiciously, he had been busy in the hangar and he didn't know Long Yun's statistics today, so he asked quite cluelessly:

"Under what circumstances, you can still replace the fire control computer and calculate the launch conditions and kill probability by yourself? -- No, did you really shoot down an enemy plane in today's 'lift-off test'? ”

"Oh, - haha! This one is naturally there. ”

Recalling a previous battle, although affected by the problem of missile interception efficiency, the results were really rich, Long Yun just laughed and did not intend to boast about the results to the engineer, he then introduced the conversation to the next topic:

"But it doesn't matter, we just need to install a target designation system.

But it's another thing, Igor, I think we can 'go one step further'," Speaking of this, Long Yun subconsciously tilted his head and looked at the blue-gray Su-27S in the hangar that was disassembling the engine, "I have already experienced the disassembly of the previous fighter equipment, which is quite beneficial to the improvement of the maneuverability of the fighter; So are we going to figure out a way to take something off my white 20 plane? ”

"- Again, some more?"

About ten minutes later, he was called by Long Yun to the reinforced hangar dedicated to the number one ace, facing the white No. 20 fighter with an aluminum alloy head cone in front of him and also out of shape because of the low tail cut, Kirilenko still couldn't help but shake his head, he felt that Viktor Rezenov, the number one killer of the Red Air Force, must be obsessed with air combat too much, and now he is simply a little crazy.

But isn't it, listening to the meaning of Comrade Major General, is to use his brains on the Su-27S, which has already been dismantled, so as to further reduce the empty weight and improve the maneuverability?

Well, even if this approach has been very successful before, but then again, in addition to the metal structure, a fighter must always have flight controls, fuel tanks and necessary electronic equipment, etc., otherwise even basic flight cannot be guaranteed; Besides, the Su-27S in front of him has already dismantled the radar and some trivial parts of the fuselage, but this guy is still greedy enough to continue to dismantle, does he want to dismantle the plane with only the engine and wings, and fly into the sky to pounce on the enemy like an eagle?

"No, no, Victor, I don't think this thing can be dismantled anymore!"

The more he thought about it, the more he felt that this thing was unreliable, Igor Kirilenko shook his head like a rattle, but in the face of the skeptical engineer, the confident Long Yun hugged his arms in front of him and smiled slightly, he knew that this cautious Kirilenko would raise objections, so he raised his hand and patted him on the shoulder, saying some of his considerations:

"Oh, Igor! You can't say it too much.

What to say about this matter, although the parts on an airplane are limited, as long as you want to dismantle, you can always dismantle some more things. Oh, you don't believe it? Then I'll tell you about it," he took two steps away as he spoke, spread out the large outline drawings of the Su-27S on the workbench, Long Yun pressed the drawings with a lamp and a wrench, and then pointed and poked at them like an instructor, and introduced his envisioned plan to Igor:

"Igor, first of all, we can start there here, yes, it's the driving motor next to the engine, do you think a fighter without radar will need such a powerful generator? Of course not, so just switch to a smaller and lighter one, I think it's about the same on the MiG-21.

And then there's here, the titanium grille that falls and retracts to prevent the inhalation of foreign objects during take-off and landing, hehe, the runway quality at the Stavropol base is not bad, and there are almost no birds or anything; I think this thing can be completely dismantled, yes, even the hydraulic retracting mechanism can be dismantled.

Also, the antenna next to the air intake is gone, that thing is useless at all.

In the end, haha, you guessed it right, there is no need to keep such a parachute; If you want to lose weight, you should be crazy, and you don't want the IFF system! ”

"IFF ...... too?"

"yes, it's inherently easy to interfere with, and I barely used it before."

Seeing Kirilenko's stunned face, staring at him as if he was looking at a monster, Long Yun remembered that the weakness of the Soviet Union's electronic level was everywhere, and even the identification of friend or foe, which was crucial for fighters, was also problematic.

In countless battles before, he had never used the landline's friend or foe identification system, not because he was a hero, but because the system was indeed worrisome. However, fortunately, the Soviet Union, which has its own system and tactical tactics that are different from those of the West, probably knows that these equipment are unreliable, and VVS and PVO do not pay much attention to the tactical role of IFF, and often rely on ground guidance and airspace division to distinguish friend from foe.
