There are now only two types of aircraft with more than Mach 2.5, the MiG-25 uses stainless steel, and the SR-71 Blackbird uses titanium alloy, because at Mach 3, aluminum alloy is already as soft as toilet paper.

Although the Tomcat would have been able to reach higher speeds, it was no longer possible to test it, and Kamal piloted the fighter and began to return to the airport.

"The experiment was very successful." Watching the fighter begin to land on the runway, Yang Wei said: "President Mhammad, we will analyze the specific data, but I feel that based on the Tomcat fighter, a similar fourth-generation aircraft has better maneuverability than the canard fighter." ”

"yes, we're going to compare now." "Now, Grumman has also developed a stealth fighter on the basis of the Tomcat fighter, which proves that our plan is very feasible," Mhammad said. ”

Tomcat fighters! Originally, it was a product of Grumman, and it was also the in-law of Mhammad's wife, but now, the relationship between the two parties is not very good. After all, Pakistan's imitation of the Tomcat fighter is considered an infringement, and Grumman once wanted to take Pakistan to court, but unfortunately, the final result of this kind of case is not settled.

However, Grumman's project is still public, and now, after the US Air Force has begun its own stealth aircraft program, the US Navy has also begun the carrier-based fourth-generation aircraft program NATF, that is, Naval Advanced Tactical Fighter, that is, the "Navy Advanced Tactical Fighter", Grumman is the main manufacturer of carrier-based aircraft in the US Navy, and of course did not hesitate to develop on the basis of the F-14, and the shape has almost come out, It's super like an F22 with a swept wing. At this time, the variable sweep wing has used the four-degree redundancy fully digital authorized fly-by-wire variable sweep wing structure. This makes this fighter have excellent high-altitude and low-altitude performance.

At the same time, this F14 improved model is equipped with the F22 exclusive Pratt & Whitney F119-PW200-TVC vector engine, strong power is of great benefit to shorten the take-off and landing distance, can be used in field airports with insufficient conditions, and at the same time, the already very powerful supersonic performance has also been further improved, and can achieve transonic Mach 1.4 with bomb pseudo-overcruise. Meantime. The new back conformal fuel tank frees the belly heavy-duty hardpoint from the clutches of the drop fuel tank, greatly increasing the actual ammo load during ranged attacks. As for the weapon system, the new generation AESA radar, developed on the basis of the AN / APG-77, is 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 F15SE "Silent Eagle" of the US Imperialist Air Force, or even more advanced.

Now, the fourth-generation aircraft developed by Pakistan will almost look similar to Grumman. After all, this is the model with the smallest radar reflection area that the Americans have come up with. Of course, Pakistan will not recognize copycats, and as early as a few years ago, Pakistan was at the forefront of the world in stealth design.

"The key to our development is the engine." "We had to have an advanced engine that we could produce ourselves. ”

The current third-generation aircraft can make do with the TF41, but the fourth-generation aircraft is absolutely not good. And Pakistan has deep pockets. It is possible to import Soviet engines, domestic fighters. You have to build your own engine, otherwise it's a huge expense.

"Yes, we are using this imported engine now, it is only for testing, and we will have to look at our own engine in the future." "We need to concentrate our efforts on tackling key problems," Mhammad said. The more advanced F110 engine will be improved as soon as possible. ”

As he was talking, Mhammad saw his secretary come over and said to him: "Mr. President, Saudi Defense Minister Prince Sultan, you have come to visit our country. The plane has already taken off. ”

Prince Sultan? Muhammad was stunned for a moment, this Royal Highness the Prince, it came really fast!

In Saudi Arabia, it is also ruled by the royal family, the richest country in the Middle East, under the rule of the Saudi royal family.

His Royal Highness Prince Sultan bin Abdulaziz bin Abdul Rahman bin Faisal Al Saud. Born in Riyadh on 5 January 1928, he is the younger brother of his predecessor, King Fahd. Educated in Islam and trained in military affairs from an early age, he became Commander of the Royal Guard at a young age, Governor of Riyadh in 1947, Minister of Agriculture in 1955, Minister of Defence and Minister of Aviation in 1962, and Second Deputy Prime Minister in 1982.

From 1962 to the present, Prince Sultan has been the top official of the Saudi defense system, and with his strong support, the Saudi military has greatly improved. He was relatively open-minded and had close relations with Western countries, especially the United States, Britain, and France.

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

And this time, Prince Sultan came to Pakistan in such a hurry because he got another news from Pakistan, Pakistan itself improved a newer model of Dongfeng-3 missile!

After the last purchase from Huaxia, these missiles entered the service of the Saudi Defense Forces and became the top secret of Saudi Arabia, and even the United States, a traditional ally of Saudi Arabia, did not know that the entire base was built in the desert to protect the security of Saudi Arabia at any time.

However, these Dongfeng-3 missiles, the technology has been a little backward, especially at that time Huaxia was still in the blockade of the West, the electronic system was very backward, resulting in the low accuracy of this missile, Huaxia has a nuclear warhead, which can make up for the lack of accuracy, and Saudi Arabia has only obtained a conventional warhead.

During the Iran-Iraq war, Iraq and Iran exchanged so many missiles, only some of them hit the target, and the rest deviated from their intended trajectory and fell outside the city.

Prince Sultan himself came, and next to him was his son Khalid bin Sultan Al Saud, Khalid is now Prince Sultan's most powerful aide, and outside observers believe that if something happens to Prince Sultan, Khalid will definitely follow his father's footsteps and become the new Saudi defense minister.

"His Royal Highness Prince Sultan is very welcome." Pakistani Defense Minister Musha'f came to greet him, and when he saw Prince Sultan, an old man in his 60s, still in good spirits, get off the plane, Musha'af immediately greeted him.

"It's a pleasure to be here." Prince Sultan said: "Pakistan's industrial development is the pride of our entire Muslim world. ”

The group got into the car and soon arrived at the presidential palace, and after some exchanges with Mhammad, despite the fatigue of the journey, the two sides took the bus again and left Islamabad.

Outside the car window, you can see the rolling mountains, which is difficult to see in Saudi Arabia, which is an endless desert area, and Prince Sultan is in high spirits.

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

"Yes, so, the mobility of the trailer chassis vehicle will be greatly limited, and we must use the off-road chassis to meet the greater needs." Mhammad said.

Trailer chassis! The Dongfeng-3 imported by Saudi Arabia uses a trailer chassis, which is only able to tow the missile away, and its maneuverability is quite limited, so it can only take the road!

Saudi Arabia has built a special launch position, and there is a road hidden under the desert to communicate with the station, which meets the needs of mobility, but this method is obviously not the best choice for Saudi Arabia!

Saudi Arabia needs an off-road chassis with high maneuverability to tow the DF-3 missile!

From where? Although Saudi Arabia has good relations with the West, it is impossible to obtain such a chassis. After all, the West will not export ballistic missiles to Saudi Arabia, and Saudi Arabia made a request to the United States back then, but the United States does not even export tactical missiles with a range of about 100 kilometers to Saudi Arabia, so Saudi Arabia cannot ask the West for this thing.

The best choice is Huaxia, but unfortunately, Huaxia does not have this kind of high-mobility chassis, and if it does, it will not use the same trailer chassis as the tractor.

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

The mountain road is winding, this is the Peshawar region, when the war with the Soviet Union, this side was the absolute front line, and now, Pakistan has a close relationship with Afghanistan, and this side of the mountainous area has become a necessary passage for the transportation of Afghan mineral resources.

Continuing north, I drove for dozens of kilometers, and when it was almost dark, I finally arrived at a station.

When the gate on the mountain opened, Prince Sultan was stunned, this is the whole mountain hollowed out, right? The cost of building this base, that's definitely very high!

"This was originally a mine, and after all the ore in it was mined, it was abandoned, and we did some processing to become the current base." Mhammad said.

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

"Your Royal Highness, we have arrived." Mhammad said.

The interior of this mountain is almost hollowed out, and there is a lot of space, and in the center, at this time, some large vehicles with multiple axles are neatly arranged.

"That's what we need!" When Khalid got out of the car, his eyes lit up.

The body is very long, the large off-road tires are taller than people, the side-mounted cab, and the middle is a cylindrical Dongfeng-3 missile. (To be continued......)
