There are only two types of aircraft with a capacity of more than Mach 5 now. MiG 25 uses stainless steel, while SR-71 Blackbird uses titanium alloy, because at Mach 3, the aluminum alloy is already as soft as toilet paper.

Although the Tomcat fighter could reach a higher speed, it was no longer possible to test it. Kamal flew the fighter and began to return to the airport.

"This experiment was very successful." Seeing the fighter jets starting to land on the runway, Yang Wei said: "President Mhamad, we will analyze the specific data, but I feel that based on the Tomcat fighter, a similar fourth-generation aircraft will have better maneuverability than the Duck fighter."

"Yes, we are going to compare now." Mhamad said: "Now, Grumman has also developed stealth fighter jets based on Tomcat fighter jets, proving that our solution is very practical."

Tomcat fighter! It was originally a product of Grumman Company, and it was also the family of Mhamad's wife, but now the relationship between the two parties is not very good. After all, Pakistan's imitation of Tomcat fighter is considered an infringement. Grumman Company once wanted to sue Pakistan in court, but unfortunately, the final result of such a case was left incomplete.

However, Grumman's project is still open. Now, after the US Air Force has started its own stealth aircraft plan, the US Navy has also begun the carrier-based fourth-generation aircraft plan Natf, which is the "Naval Advanced Tactical Fighter". Grumman is the main manufacturer of the US Navy's carrier-based aircraft. Of course, it did not hesitate to develop it on the basis of the F-14. The appearance has almost come out, which is like the F22 using the swept-changing wing. At this time, the variable swept-wing wing has used the four-degree fully digital authorized fax variable swept-wing structure, giving this fighter an excellent high-altitude and low-altitude performance.

At the same time, this F14 improved model is equipped with a Puhui F119-pw200-tvc vector engine exclusively for F22. The strong power is of great benefit to shortening the take-off and landing distance and can broaden the scope of application in field airports with insufficient conditions. At the same time, the already very powerful supersonic performance has been further improved, and it can realize a transsonic 4 Mach with pseudo-super patrol. At the same time, a new back conformal fuel tank is added, freeing the heavy-load hanging point of the abdomen from the clutches of the secondary fuel tank. It greatly improves the actual load capacity during long-range attacks. As for the weapon system, the new generation of AESA radar developed based on an/apg-77 can be compatible with AIM-9x, AIM-120d and almost all tactical air-to-ground weapons of the US military. After the improvement, the basic performance of the Tomcat fighter will be comparable to the F15 color "Silent Eagle" of the US Air Force, and is even more advanced.

Now, the fourth-generation aircraft developed by Pakistan almost has a similar appearance to that of Grumman. After all, this is a model that Americans have created radar reflection area. Of course, Pakistan will not admit to being a copycat. As early as a few years ago, Pakistan had already reached the forefront of the world in stealth design.

"The key to our development is the engine." Yang Wei said: "We must have an advanced engine that can be produced by ourselves."

Nowadays, the third-generation aircraft can be used to make do with the TF41, but the fourth-generation aircraft is absolutely not possible. Pakistan is rich and powerful. It can import Soviet engines and domestic fighter jets. It must be based on its own engines, otherwise, this will be a huge expense.

"Yes, we are using this imported engine now, just for testing, and we still have to look at our own engine in the future." Mhamad said: "We must concentrate our efforts on tackling key issues and improve the more advanced f110 engine as soon as possible."

As he was speaking, Mhamad saw his secretary coming over and said to Mhamad: "Mr. President, Prince Sultan, Saudi Defense Minister, came to visit our country and the special plane has taken off."

Prince Sultan? Mhamad was stunned. His Highness, this prince came so quickly!

In Saudi Arabia, it is still under the royal rule. This richest country in the Middle East is under the Saudi royal rule.

Prince Sultan, whose full name is Sultan bin Abdul Aziz bin Abdul Rahman bin Faisal Alshat. He was born in Riyadh on January 5, 1928. He was the younger brother of the former king Fahd. He received Islamic education and military training since he was a child. He served as the commander of the Royal Guard when he was young. He served as the Chief Executive of the Riyadh Region in 1947, as the Minister of Agriculture in 1955, as the Minister of Defense and Minister of Aviation in 1962, and as the Second Deputy Prime Minister since 1982.

From 1962 to now, Prince Sultan has been the highest commander of the Saudi defense system. With his strong support, Saudi Arabia's military strength has been greatly improved. His ideas are relatively open-minded and closely related to Western countries, especially the United States, Britain, France, etc.

Saudi Arabia does not have any defense industry, and all weapons are purchased from abroad, including Saudi Arabia's national sword, which were purchased from China under the coordination of Pakistan.

And this time, Prince Sultan came to Pakistan so hurriedly because he got another news from Pakistan that Pakistan itself improved the updated Dongfeng-3 missile!

After purchasing it from China last time, this batch of missiles entered the Saudi Wehrmacht and became Saudi Arabia's highest secret. Even Saudi Arabia's traditional ally, the United States, did not know that the entire base was built in the desert and protected Saudi Arabia's security at any time.

However, the technology of these Dongfeng-3 missiles was already a little behind, especially when China was still in the Western blockade at that time, and the electronic system was very backward, which led to the low hit accuracy of this missile. China has nuclear warheads, which can make up for the shortcomings of accuracy, while Saudi Arabia obtained only conventional warheads.

During the Iraq-Iran War, Iraq and Iran fired so many missiles at each other, only a few of them hit the target, and the rest deviated from the scheduled track and landed outside the city.

Prince Sultan came in person, and the one who followed him was his son Khalid bin Sultan Al-Sharat. Harid is now Prince Sultan's most powerful assistant. Observers from the outside world believe that once Prince Sultan has any accident, Khalid will definitely become Saudi Arabia's new defense minister if something happens to Prince Sultan.

"His Highness Prince Sultan is very welcome." The person who came to greet Pakistan's Defense Minister Musha Af. Seeing Prince Sultan, an old man in his sixties, still getting off the plane in a good spirit, Musha Af immediately went up.

"I am very happy to be here," said Prince Sultan: "The industrial development of Pakistan is the pride of our entire Muslim world."

The group got into the car and soon arrived at the Presidential Palace. After having some communication with Mhamad, regardless of the fatigue of the journey, both sides took the car again and left Islamabad.

Outside the car window, you can see the rolling mountains. It is difficult to see this scene in Saudi Arabia in the endless desert area. Prince Sultan is very excited.

"It's really hard to walk in this mountainous area," said Prince Sultan.

"Yes, so the mobility of a tow chassis vehicle will be greatly limited. We must use an off-road chassis to meet greater needs." Mhamad said.

Trailer chassis! The Dongfeng-3 imported by Saudi Arabia uses a trailer chassis, which can only tow missiles away. Its maneuverability is quite limited and it can only be taken on the highway!

Saudi Arabia has built a special launch position, with roads hidden in the desert and connecting to the station, which meets the needs of mobility. However, this method is obviously not the best choice for Saudi Arabia!

Saudi Arabia needs a high-motorized off-road chassis to drag the Dongfeng-3 missile!

Where? Although Saudi Arabia has a good relationship with the West, this kind of chassis is impossible to obtain. After all, the West will not export ballistic missiles to Saudi Arabia. Saudi Arabia asked the United States for national demands, but the United States did not even export tactical missiles with a range of about 100 kilometers to Saudi Arabia. Therefore, Saudi Arabia cannot ask the West for this thing.

The best choice is Huaxia. Unfortunately, Huaxia does not have such a high-motorized chassis. If there is one, it would not be possible to use a tractor-like trailer chassis.

Now, Saudi Arabia finally has a new choice, which is Pakistan! Pakistan already has a high maneuverable off-road chassis!

The mountain road is winding, and this is the Peshawar region. When we were fighting with the Soviet Union, this was the absolute front line. Now, Pakistan has close ties with Afghanistan, and the mountainous areas here are already a necessary channel for Afghanistan's mineral resources transportation.

Continue north and drive for dozens of kilometers. When the sky is almost dark, I finally arrived at a station.

When the gate on the mountain opened, Prince Sultan was shocked. This was emptying the entire mountain, right? The cost of building this base is definitely very high!

"This place was originally a mine. After all the ores inside were mined, they were abandoned. We processed them and became our current base." Mhamad said.

The lights were on in the tunnel, and after walking about a few hundred meters, the car stopped.

"Your Highness, we are here," said Mhamad.

Almost all the inside of the mountain was hollowed out, with a large space. In the center, some large multi-axle vehicles were arranged neatly.

"What we need is this kind of chassis!" After Khalid got off the car, his eyes lit up.
Chapter completed!
