The military industry is investigating you and you are investigating me? I sell fishing rods!

Jian 21, this is a brand-new fighter developed by Su Heng combining the advantages of Jian 10 and Jian 11.

In terms of size, Jian 21 is much smaller than Jian 11, and not much larger than Jian 10.

Relatively speaking, its ammunition load and range are not inferior to Jian 11, and even surpass Jian 11 in terms of ammunition load!

In addition, Jian 21 also has the excellent maneuverability of Jian 11 and Jian 10!

It can be said that this is a perfect carrier-based aircraft!

Not only a carrier-based aircraft, but also a very good ground fighter when it is put on the shore!

Of course, letting Jian 21 go ashore is not the best choice. As we all know, due to the constraints of take-off and landing conditions, the construction cost of carrier-based aircraft is generally much higher than that of ground fighters.

So unless under special circumstances, even the Black and White Eagle is not so arrogant to let the carrier-based aircraft go ashore...

And Jian 21, as a carrier-based aircraft designed by Su Heng specifically for the navy, is also the same.

Among the three fighters, Jian 10 Kai, Jian 11 Kai, and Jian 21, Jian 10 Kai and Jian 11 Kai are both twin-engine heavy fighters.

Jian 11 Kai is an ordinary heavy fighter with a maximum take-off weight of 30,368 kg, a maximum bomb load of 17,519 kg, a practical ceiling of 22,000 meters, a maximum flight speed of 2.8 Mach (3,427 km/h), a maximum range of 4,800 km, and a combat radius of 2,200 km.

With auxiliary fuel tanks, the maximum range can reach 5,500 km!

The Jian 10 Kai is a heavy stealth fighter, which was improved by Su Heng based on the technical parameters of Jian 10 and the Raptor of the Black and White Eagle.

The maximum take-off weight of Jian-10 Kai is 30,112 kg, the maximum bomb load (internal magazine) is 8,500 kg, the maximum bomb load (including external attachments) is 15,367 kg, the practical ceiling is 22,000 meters, the maximum flight speed is 2.8 Mach (3,427 km/h), the cruising speed is 1.8 Mach (2,203 km/h), the maximum range is 4,200 km, the combat radius is 2,000 km, and the front radar reflection area is 0.0001 square meters.

When carrying auxiliary fuel tanks, the maximum range of Jian-10 Kai can be increased to 6,000 km!

Like Jian-21, the fuselage materials of the three fighters are all T400-grade carbon fiber materials.

As a new material leading the world, T400 carbon fiber has an absolute advantage beyond imagination in terms of strength, toughness, corrosion resistance, and high temperature resistance!

Therefore, the J-10, J-11 and J-21 do not need to add any other messy materials, and the manufacturing cost is several orders of magnitude lower than the original fighter!

In terms of avionics system, Su Heng also made a new upgrade.

Both fighters are equipped with a new avionics system designed by Su Heng, and Su Heng named it Shuguang!

The Shuguang avionics system includes an active phased array radar system, a Shuguang communication system, a fire control system, a Shuguang biological control system, ...

The Shuguang biological control system includes the biological signal driving helmet of the previous twin-tailed drone.

The original driving helmets of the Jian-10 and Jian-11 fighters were much more backward than Su Heng imagined, so Su Heng directly abandoned them after reading the information.

Then he replaced them with biological signal driving helmets without hesitation.

Although the biological signal driving helmet is much more expensive than the original flight helmet.

But the functions of the two are completely different. A biological signal helmet can be fully compatible with most of the fighter operating systems, and most of the old operating platforms on the Jian-11 and Jian-10 can be directly discarded!

Even if it weren't for the need for safety, and some emergency control equipment needed to be left, the entire cockpit could be fully compatible with the bio-information control helmet.

Similarly, the same avionics system was also installed on the Sword 21.

In addition to the basic configuration, the three fighters were almost completely replaced by Su Heng from the inside out.

Even the engine, one of the most core components, was upgraded by Su Heng. The biggest constraint that restricted Longguo's research on engines was materials, and Su Heng was the least lacking of materials!

It's a pity that the time is a little short. If you want to develop a new engine, even with the help of the spiritual space, it will not be completed in a day or two. Otherwise, Su Heng would like to replace a more advanced engine.

In Su Heng's opinion, the current engine is still a little lacking.

Shaking his head, Su Heng shook off the idea in his mind.

Then he looked at the three new fighters in front of him.

With a thought, the next moment, the models of the three fighters began to "proliferate and divide" as before.

At the same time, not far away, the virtual data models of the black and white eagle fighters also quickly emerged.

Not long after, hundreds of fighter planes appeared in front of Su Heng.

"Then... let's start!"

Looking at the hundreds of fighter planes in front of him, Su Heng's eyes moved slightly.

Along with Su Heng's thoughts, the next moment, the spiritual space was like time and space stretched, directly expanding countless times!

The distance between hundreds of fighter planes was also stretched countless times at this moment!

Then, hundreds of fighter planes rushed towards each other in an instant...

…………

In a blink of an eye, three days passed quietly.

Three days later, Su Heng pushed open the door of the laboratory that had been closed for a long time.

After a day's rest, Su Heng directly approached Yu He.

Compared with before, Yu He looked much haggard, as if something had happened.

"What happened to Yu Gong?"

Looking at Yu He who looked haggard, Su Heng was a little confused.

Hearing this, Yu He shook his head slightly and said: "It's okay, Mr. Su, it's just that I haven't had a good rest in the past few days. The air here is too dry, and I'm a little acclimatized."

"Is the air too dry?" Su Heng glanced at the temperature and humidity detector hanging on the wall next to him, becoming more and more confused.

However, after thinking about it, Su Heng did not continue to inquire further.

Instead, he said directly: "Yu Gong, if there is anything wrong with us, you can tell me directly..."

Hearing this, Yu He smiled bitterly, and then said: "Mr. Su, you are worrying too much. I'm really fine. I've just been thinking about the fighter planes for a while, and I'm a little angry."

Fighter plane?

Su Heng understood.

Then he smiled and said: "If that's the case, then Yu Gong, you don't have to worry about it. I've already solved the fighter plane issue."

"Resolved?" Yu He was startled and didn't react. Then he suddenly got excited, then quickly looked at Su Heng and said excitedly: "Mr. Su, are you serious? Sword Ten and Sword Eleven Is it possible to mass produce it here?”

"Ten of Swords and Eleven of Swords?" Su Heng shook his head slightly and said, "No, neither Ten of Swords nor Eleven of Swords are productive."

Hearing this, Yu He froze on the spot. The excitement he had just generated was like being doused with ice water at this moment, and instantly became cold.

But at this moment, Su Heng continued: "The Jian 10 and Jian 11 fighters are too backward, especially the Jian 11. It is completely unnecessary for us to produce such fighters. It is time-consuming and labor-intensive, and it is impossible to produce them." The main fighters against the Black and White Eagles, so I upgraded them."

"Upgrade?" Su Heng's voice made Yu He, who was still a little disheartened just now, startled, and immediately cheered up, but then, as if he thought of something, Yu He showed a wry smile again, " Mr. Su, please stop making fun of me, a bad old man. I know you are comforting me, but Mr. Su, you don’t have to do this at all. I, a bad old man, have never seen any storms. The era when we had nothing has passed. It doesn’t matter how many years it lasts.”

After a pause, Yu He sighed slightly and said: "Those of us at the rear don't have anything to do with it. We just suffer from the young men at the front. They are all our heroes, but if our weapons can be more advanced, They don’t have to be heroes at all!”

hero!

What this is, is an honor, the highest honor.

But they are even colder numbers!

Behind every hero is blood and tears!

Hearing Yu He's voice, Su Heng couldn't help but sigh slightly.

After a moment of silence, Su Heng looked at the sad old man in front of him, and then smiled and said: "Yu Gong, don't worry, the past is in the past, our heroes will no longer be just a number in the future, I promise you! "

After saying that, regardless of what He Duo said, Su Heng took the box in his hand and walked to the computer next to him.

Under Yu He's gaze, he directly inserted a data cable into the box and connected it to the computer host.

Noticing Su Heng's movements, Yu He was a little confused, but he didn't say anything more and followed him to the computer.

"Mr. Su, what is this?"

Not long after, when he saw the data displayed on the computer, Yu He couldn't help but open his eyes wide.

"This is Sword Twenty???"

When he saw a three-dimensional view appearing on the screen, Yu He was shocked.

"Mr. Su, how did you know the data of Jian Twenty?"

Jian Twenty is currently a stealth fighter designed by Tianfu Aircraft Research Institute that is still online and has not been offline!

The information is classified as top secret in the National Defense Forces. Except for relevant researchers, the number of people who know this top-secret information can be counted on their fingers.

As for Su Heng, although he had asked before and told Su Heng some information about Sword Twenty, Su Heng did not ask for specific technical data.

And now, what is the three-dimensional view in front of me if it's not Sword Twenty?

The structure is almost identical to their sword twenty-one!

"Sword Twenty?" Hearing Yu He's exclamation, Su Heng raised his eyebrows slightly, "Is your Sword Twenty also like this?"

Hearing this, Yu He was startled, and then he seemed to have thought of something, and his eyes suddenly widened: "Mr. Su, you don't know the data of Jian Twenty?"

"..." Su Heng was silent.

Should he know?

Seeing this, Yu He also fell into silence.

He was even more entangled in his heart. Reason told him that Su Heng should not know, but if Su Heng didn't know, wouldn't it be even more outrageous?

Sword Twenty is a fifth-generation fighter jet that they spent many years and a lot of manpower and material resources to finally develop.

And Su Heng, in just a few days, he got their sword twenty?

At this moment, Su Heng slowly opened his mouth and said: "These are the Ten Sword Changes, the Sword Eleven Changes, and the Sword Twenty-One I have designed in the past few days."

As he spoke, Su Heng pointed to the three-dimensional view on the screen and said, "This is the Jianshi modification. I improved the Jianshi fighter based on the data you provided, Yu Gong."

"???"

"Improved Sword Judgment? Sword Judgment Modification?"

Yu He's eyes widened. Is this the Ten Changes of Sword?

The first update has been delivered. A picture of Sword 21 will be attached later.
