In the Falklands War in 1982, although Argentina finally lost, their army still had a brilliant performance, which was the use of super flag attack aircraft, launched Exocet missiles, and sent the Shelfield to the bottom of the sea.

Use a large number of maritime patrol planes to search for the traces of the opponent's ships, and after discovering them, notify your own aircraft group, and then, the super military flag is dispatched, and after refueling in the air at sea, it pounces on the target at an ultra-low altitude, pulls it up dozens of kilometers away, locks the target with radar, launches missiles, and then goes back.

It is precisely because of the stimulus of this attack that J-7 continued to develop it, otherwise, it might be shelved like J-9.

After all, the country's military spending is in short supply.

Before the J-7, the old H-6 could also be equipped with missiles, using wing pylons on both sides to each mount an anti-ship missile to carry out sea attacks.

However, it is destined that it is impossible for the old H-6 to penetrate the defense at an ultra-low altitude, and it can only be launched from a high altitude and slowly passing 34 kilometers to the target, and if it is in a war, at this distance, people's air defense missiles are already enough, such as the British Navy's Sea Javelin, which can easily shoot down the H-6, so this attack method is very unreliable, and the navy must have this kind of fighter-bomber that can attack at an ultra-low altitude and skim the sea, and when necessary, it can also have a certain self-defense capability.

J-7, now there is no need to drop bombs on land at ultra-low altitudes, just fly over the sea and throw anti-ship missiles, which is also the reason why in the future, when the Air Force is equipped with J-7, there will be accidents from time to time, this aircraft is designed to take into account the need for ultra-low-altitude flight on land, after all, the situation on land is much more than on the sea.

This is a matter of the future, and now the mission of the J-7 is to carry anti-ship missiles, so where are its anti-ship missiles hanging? Of course, it's the inside of the wing, the part that is the most stressed!

If it was an YJ-81, there would be no problem hanging in the middle, but when the design of this aircraft began, there were only YJ-1 anti-ship missiles, codenamed YJ-1, and export codenamed C101.

(To briefly introduce that domestic anti-ship missiles, for domestic self-use, are named Eagle Strike, such as Eagle Strike 81, which is now the most commonly used, and at the same time, the export model is called C801, which can be regarded as a tradition starting from the Eagle Strike-1 anti-ship missile.) ）

When the YJ-1 anti-ship missile was developed, the plan was to provide an air-to-ship missile for the "Water Bomb-5", of course, it can also be used as a ship-based anti-ship missile, and when this missile was designed, the idea was very advanced, this is an ultra-low-altitude, supersonic and multi-purpose anti-ship missile, and moreover, the liquid ramjet engine is used as the main power, equipped with two solid boosters, if you look at it from the appearance, it can even have a slight shadow of the sun-burning anti-ship missile, of course, in fact, there is a big difference.

Under the weak domestic scientific research force, if this missile is completely self-developed, it is impossible, so, this missile is actually a reduced version of the YJ-3 missile, the length is reduced to 7.5 meters, and the launch weight is reduced to 1500 kilograms, however, because of the reduction of fuel, the range is also reduced to about 50 kilometers, but as a supersonic anti-ship missile, it is very attractive.

At that time, it happened to be the era when the idea of saturation attack by the Soviets was popular, and it could be regarded as catching up with the trend of the times, and when the J-7 was being developed, only this missile was the most suitable, after all, the YJ-1 missile was the main air-to-ship missile equipment of the Navy according to the plan.

Well, the problem comes, the wing of the J-7 is designed with a certain index, the carrying capacity of the inner pylon is 1650 kg, and the middle pylon is 1250 kg. Therefore, in order to mount a 1,500-kilogram YJ-1 missile, the missile can only be mounted on the inner pylon under the wings.

Therefore, the inner pylon, which is reserved for the YJ-1 missile, then, the auxiliary fuel tank, can only be mounted to the middle pylon, of course, in addition to the middle pylons on both sides, under the belly, it is also possible to mount an auxiliary fuel tank, so that the scheme of three auxiliary fuel tanks is realized.

"However, the YJ-1 missile has been dismounted, and now we also have a mature YJ-81 missile." Qin Feng continued to ask towards Old Chen.

The YJ-1 project has a lot of development problems, the most important of which is the problem of guidance and control at high speed, which is not easy to solve, and was finally dismounted, while the YJ-81 anti-ship missile was successful.

The development of this missile began in the mid-70s, and in 1979, the first flight test was successful. As a missile of a new generation, it is very versatile, in addition to airborne, it can also be shipborne and even ship-based, and even ship-based vehicles.

This is a solid-propellant anti-ship missile, which is very similar to the Exocet missile in appearance, so in the National Day parade a few years ago, when it first appeared in the world, it was called China's Exocet.

The volume of this missile is much smaller, and at the same time, its weight has also been reduced, only more than 800 kilograms, so for the J-7, it can not only be pyloned internally, but also in the middle.

Qin Feng knew all this, so when Old Chen talked about this issue, Qin Feng also raised it.

"yes, so our mount plan has changed." Chen Lao said: "Our inner wing and middle pylons can be mounted with anti-ship missiles, and one J-7 can be equipped with four anti-ship missiles. ”

The middle pylon is also enough, so the number of mounted anti-ship missiles has doubled, speaking of which, Chen Lao is still very proud, and then, he remembered Qin Feng's question just now: "But what, our design has been fixed, so the auxiliary fuel tank can only be hung in the middle, however, for our J-7, our range is already large enough, and there is enough fuel in the middle, and the time left in the air is too long, and it is unbearable for the pilot's physical strength." ”

Qin Feng nodded, yes, he remembered the American Thunderbird Air Show Team, people can fly long distances, these trainings are all blanks in China.

"Understood, I look forward to a smooth transition for us." Qin Feng said to Chen Lao, and continued to watch the technicians compare the auxiliary fuel tank, even if it is not hung on the inside, this auxiliary fuel tank is at least more than a thousand liters.
