In fact, whether it is Sirius's conventional layout carrier-based version of the J-20B, or Neptune's variable-swept wing carrier-based version of the J-20C, as long as any of these two aircraft is made, it is the strongest carrier-based aircraft on the earth.

The overall performance of the two is comparable to that of the land-based F22, not to mention the reduced version of the F35, which is just not comprehensive enough compared to the J-20.

Because the functions are not comprehensive enough, the comparison between these two aircraft is mutually advantageous, and there is no one-sided situation, and neither can be a big package.

The conventional layout of the J-20B is suitable for attack aircraft, and the J-20C with variable sweep wing is suitable for short-wing superior fighters.

The overall efficiency of the two aircraft can exceed that of the land-based J-20A on the aircraft carrier, but it takes up more space.

After determining the overall development idea for the follow-up, it was almost dinner time, and Mu Feng beckoned the two Sirius sisters to go to the restaurant for dinner.

The two of them really got into it, and they kept thinking about it while eating, and immediately after eating, they went to the scientific research center.

Mu Feng knew that they should have some ideas for improvement, so he ran over at night in a hurry, so he followed and watched.

After entering the scientific research center, Sirius opened the internal structure of his plane and said to Mu Feng:

"Commander, I am ready to reduce the maintainability of the aircraft to a minimum."

Mu Feng was a little puzzled: "Maintainability? Minimum? ”

Sirius nodded: "It's just that in addition to the bomb magazine and external equipment, the entire aircraft as a whole is formed in one piece."

"Doing so again reduces the overall weight of the structure, while also increasing the strength of the body and increasing the space inside the body.

"But after this change, the plane cannot be disassembled, which means that any internal failure cannot be repaired.

"If the exterior is damaged, it can be repaired, but as long as there is any failure of the internal equipment, the aircraft will be scrapped."

Mu Feng was stunned for a while after hearing this, this idea is equivalent to a one-time 3D printing of the entire aircraft, which is impossible to realize on the earth.

Only this world's Ship Girl tech tree can complete this production method.

According to the estimation given by the system, after the ship is equipped with this kind of aircraft, each generation will require 80 units of resources, which is not high for herself.

So Mu Feng nodded: "Okay, you can, just do it!" ”

Neptune next to him immediately shouted: "I want it too, and my plane will change like this!" ”

Mu Feng nodded directly and said, "Yes, no problem." ”

A fourth-generation heavy fighter has 80 unit resources, Guangdong and Liaoning have a total of 128 units, and if all of them fall, they need to consume 10,240 units of resources to make up for it.

For ordinary commanders, this is going bankrupt, but for himself, this is not a big problem, so Mu Feng directly agreed.

Mu Feng felt that in this era, unless he made a mistake, how could these two planes fall?

After Sirius and Neptune were confirmed, they immediately went to modify the internal structure design of the aircraft and changed it to a one-piece plan.

After losing weight in this way, the two continued to make other adjustments.

Sirius's attack aircraft extends the main wing of the aircraft forward, and the part of the fuselage and the main wing is expanded outward, so that the entire fuselage and the entire main wing are completely integrated.

The wing-hull connection is transitioned in as smooth a way as possible, and the entire shape of the aircraft, with the exception of the tail, becomes almost a relatively sharp isosceles triangle.

Such a modification was able to improve stealth performance, increase the wing area, increase the load capacity, increase the interior space, and increase the fuel load of the internal tanks.

Sirius then shifted the two engines that had been close together to each other to each side, leaving some distance between them.

Increasing the engine spacing will slightly reduce the handling of close rolls, but this ability is not too important for the fourth-generation stealth attack aircraft.

And even if it is reduced a little, this performance will still not be worse than that of the third-generation aircraft, and the engine spacing of the J-15 and F14 is already very large.

This is in line with the improvement direction of attack mechanization set by Mu Feng.

After this operation, the fuselage body was suddenly widened, and correspondingly, the width of the main magazine located in the middle of the fuselage was increased from more than 2 meters to more than 3 meters.

Sirius extended the main magazine to 6 meters, adding a new narrower main magazine between the two engines, also 6 meters long.

The small magazine on the outside of the fuselage was also expanded because the wing fuselage was completely smooth and fused, and Sirius expanded it naturally.

The side magazine, which originally held one melee shell, has been expanded to hold two shells, and can be used to attach additional cannon pods.

At the same time, the excess area behind the side magazine, outside the engine, the main wing and the fuselage was larger.

Sirius has a magazine on either side of it, capable of holding two medium-range shells each.

These magazines occupy a certain amount of space in the fuel tanks inside the wings, but the wings are also expanded, and the two offset the internal fuel capacity.

After Sirius made these changes, he turned back to Mu Feng and said:

"Commander, I would like to develop a specialized air-launched anti-ship missile on the basis of the YJ-12.

"The length is limited to less than 6 meters, the wingspan is less than 0.6 meters after folding, the weight is 1.5 to 2 tons, and the performance parameters are basically the same as Eagle Strike 12."

"The J-20B attack aircraft I modified has a built-in magazine, which can carry 4 to 6 of these anti-ship missiles, plus the air-to-air missiles with expanded and new side magazines, which can basically achieve full load built-in."

Mu Feng looked at these changes in Sirius, listened to her plan, and was a little puzzled:

"It's no problem to develop a special missile with a new airframe, but if this is modified on the basis of the YJ-12, it shouldn't be too difficult.

"But with all the built-in 12-ton payload, can the aircraft still be able to cruise at supersonic speed? Can the top speed reach 2 times the speed of sound? ”

Sirius smiled and said: "When taking off with a full load of 40 tons, of course, it is impossible to achieve overcruise, in this case she is a subsonic stealth attack aircraft, or simply a bomber."

"When you only bring short-range combat missiles, medium-range air-to-air missiles, and a small part of fuel for air combat, you can achieve supersonic cruise, and the afterburner speed can exceed twice the speed of sound."

Mu Feng thought for a moment: "Yes, then design it like this." ”

Sirius nodded: "This is confirmed, and then I am also going to cancel the crew facilities, cancel the personnel operation interface and various instruments at the front of the fuselage, and move the control center of the aircraft to the middle of the fuselage."

Mu Feng was stunned for a moment: "You want to change to a drone?" ”

Sirius nodded: "The ship's plane doesn't need to be controlled by people, so the operation interface and instruments can be canceled, but the control system must still be retained."

"Because the ship's mother also operates the aircraft through the control system, but it is remotely controlled.

"If the control system is removed, the ship mother needs to directly control every specific structure on the aircraft, which is too tiring and inefficient.

"Removing the crew facility saves space and weight, but the consequence is that the plane can't be used as a means of transportation, and we can't move quickly in that kind of aircraft."

Mu Feng heard it and immediately said: "Your plane is not the fastest in the first place, the task of moving the tool quickly is handed over to Neptune's J-20C, you delete all the crew-related facilities." ”

Sirius immediately nodded and said, "Okay, this will improve the performance of the aircraft even further." ”

As soon as Mu Feng and Sirius finished speaking, Neptune next to him immediately cried out with a sad face:

"Commander, you're biased, and I was about to delete the member facilities, so you left this task to me......"

Mu Feng couldn't cry or laugh when he heard this, and went over to touch Neptune's hair:

"Your fastest plane must be used as our high-speed transportation, this really can't be deleted......"

Neptune flattened his mouth: "Then I specially designed an airplane for high-speed transportation?" ”

Mu Feng frowned slightly and said: "Of course you can, but we already have two kinds of aircraft to be developed, and if you come to the third one, the workload will be too big." ”

Neptune thought for a moment: "The rest of the two planes can be designed to be exactly the same, bringing together as many members-related facilities as possible and designing them into interchangeable modules.

"The unmanned module is a fuel tank, and the surface of the fuselage is smooth when installed, and the manned module has pilot-related support and control facilities, and it is a prominent nacelle."

"This is okay...... Mu Feng added a little, "Originally, the personnel compartment was canceled, that is, the protrusion was canceled, and the internal space became a fuel tank, so let's do it!" ”

"Okay!" Neptune promised to get to work.

The sisters' job tonight was to reorganize the requirements and design goals.

Sirius's attack aircraft is designed to carry as much fuel and ammunition as possible within the maximum take-off weight of 40 tons, and to carry as much load as possible to ensure the highest possible stealth capability.

Neptune's fighter plan is to increase the speed and maneuverability as much as possible, and ensure the stealth ability in the three states of assault, cruise, and air combat as much as possible.

The two of them tossed until more than 10 o'clock in the evening, and still had no intention of stopping, Mu Feng could only forcibly call a pause and pull the two of them back to the room to sleep.

The next morning, after the Sirius sisters had eaten, they immediately went back to the scientific research center to continue their work.

In the evening, the design goals of the two aircraft were basically determined, and the next step was to complete the detailed design with the help of the scientific research system in accordance with the concept and solution of the discussion.

Designing two fourth-generation aircraft at once is not something that can be done in a day or two.

The two aircraft carriers, Liaoning and Guangdong, are the most sensitive to aircraft, and they knew that Mu Feng was taking the two sisters Sirius and Neptune to study the new aircraft, so they also followed the past to inquire about the situation.

When designing the Sirius sisters, they will also take into account the opinions of the two aircraft carriers, which can avoid some unnecessary workload and slightly increase the speed of development.

Mu Feng doesn't care if he can be useful or not, he can follow and help as much as possible.

At the same time, the mothership was still heading southwest, and the weather in the sea area it passed through for the past two days was not good, it was either windy or rainy, and it also encountered a typhoon.

Although the design of the mothership is capable of resisting a 17-level typhoon, Mu Feng will not be able to find trouble to break through the typhoon, and quickly bypass it if he finds it in advance.

When the sea conditions were bad, Mu Feng asked the mothership to slow down slightly, and the average speed of the two days had dropped to about 20 knots.

The hull was wobbly and uncomfortable, and it rained from time to time, and everyone was not in the mood to go to the deck to play, so they all stayed in the cabin to kill time.

The weather remained unpleasant for the next two days, and it was not until the third day that the mothership, which had been bumpy for five days, finally arrived at a relatively peaceful sea.

This is already the 19th day of sailing, and the ocean-going carrier has continued to sail 23,700 kilometers, and the straight-line distance from the departure point has reached almost 20,000 kilometers.

Now the weather is cloudy, but there is no wind on the sea, Mu Feng immediately asked Liaoning and Guangdong to adjust the number of carrier-based aircraft, increasing the number of early warning aircraft to 12, and the two have a total of 24 aircraft.

Then let the two of them unfold the hull of the ship at the same time on the sea surface, release all 24 AWACS aircraft together, and explore towards the large fan shape of 270 degrees ahead.

The task of the AWACS aircraft is not only to check the conditions of the surrounding sea and find out if there is any trace of the ship, but also to observe the surrounding cloud conditions from the sky.

Although there are no professional weather forecasting facilities and personnel in the Mufeng fleet, the aircraft carrier can also estimate the movement of the clouds by observing it.

The Air Police 600 used by the Mufeng fleet has a cruising speed of about 500 kilometers per hour, a maximum range of 3,000 kilometers, and a combat radius of 1,500 kilometers.

It is now possible to explore the surrounding conditions within a 1500 km radius in one go.

The planes of Guangdong and Liaoning flew for almost an hour, and Liaoning reported to Mu Feng:

"Commander, it's starting to rain 600 kilometers to the southwest, and the weather is not good further south, and it's sunny in the northwest, so I suggest turning around and heading northwest."

Mu Feng nodded and agreed: "Okay, now turn to the northwest, and the AWACS aircraft will continue to explore forward to see the cloud conditions on the farther route......"

The mothership's 100,000-ton hull slowly turned, and Guangdong and Liaoning continued to probe the weather ahead.

The AWACS aircraft flew for three hours in a row, and it was basically sunny within 1,500 kilometers to the northwest.

After determining that the route was fine, the AWACS aircraft of Liaoning and Guangdong began to return, and the mothership began to accelerate, which was soon raised to 35 knots.

Three hours later, the mothership passed through the rainy area and reached a sun-drenched sea.

Finally seeing the long-lost sunshine, the ship's wives all ran out and went to the deck to bask in the sun, and the two Sirius sisters were also called out to rest by Mu Feng.

Over the next two days, the mothership's 16 gas turbines were turned on in groups, allowing the mothership to maintain a high speed of 35 knots at a relatively calm sea.

With the lesson of the rainy season a while ago, from this day on, Mu Feng asked Guangdong and Liaoning to release early warning aircraft once a day to check the status of the route 1,500 kilometers ahead in advance.

At a speed of 35 knots, the mothership travels a distance of about 1,500 kilometers per day.

On the third day after the turn, on the morning of the 21st day of going to sea, Liaoning routinely released an early warning aircraft to explore the route, and after an hour of flight, it reported to Mu Feng:

"Commander, there's not very good news, the weather is starting to get worse 600 kilometers ahead, and we may be turning again......"

Mu Feng nodded: "It's no problem to turn, let's see which side has the best sea conditions first." ”

"Hmm." Liaoning continued to search forward, and reported again after another hour, "Commander, the best direction for the weather this time is the south, and the north is okay."

"And the direction we're going in now is getting worse and worse, and it's stormy 1,000 kilometers away...... Wait a minute...... What's that......"
