On the radar station, the wind was biting, and in a makeshift radar room, the radar hand was watching the screen closely.

The goal is climbing!

"The target is eight thousand in height, has crossed the border and is continuing to climb towards us." The radar soldier shouted.

Qin Feng's speculation was not bad at all, because the opponent's base was close to his own border, so after the other party took off, he had already flown across the border while climbing.

Why didn't it fly south first, and then come back when it was high enough?

The answer is no.

If they fly south and fly back, they will go around in circles and waste fuel, and for them, the airspace here is extremely clean and thorough, just like their own airspace, the sky is high and the birds can fly, they can fly as they want, they don't care at all.

If that's the case, why go around in circles?

They didn't know that this time, they would be intercepted by the opposite side.

Take off, take off!

After the two engines started normally, Wang Yang turned on the afterburner, and the fighter plane slid on the runway, and then pulled up. Although it was the first time to take off from the airfield here, at the civilian airfield of 3,500 meters, they had already practiced many times, and they had long been confident about all this.

The two turbojet-7 engines emitted a blazing tail flame, and at this time, the engines never turned off the afterburner, which is also an advantage of the J-8 as an interceptor.

Relying on the advantages brought by the two engines, the climb rate of the J-8 can reach about 200 meters per second, and there is a gap of more than 300 meters to the third-generation maneuver in the West, but for China, this is already very unnatural.

In this way, it is 12,000 kilometers per minute, and it takes less than two minutes to climb to the maximum altitude, and at the same time, according to the operating regulations, the afterburner of the engine cannot be turned on for more than three minutes at a time.

Emergency take-off is so efficient, Wang Yang piloted the fighter plane, quickly climbed upward, and at the same time, the ground radar station began to guide.

This is also the most common form of homeland air defense, guided by ground radar, which guides the fighter near the target and then launches an attack, and now, if you want to use a jump attack, then ground guidance is even more important.

While climbing, Wang Yang turned on the radar, warmed up the internal electron tubes, and activated the Thunderbolt-2 missile mounted under the wings.

In September 1958, there was an air battle between the air force and the enemy aircraft on the opposite side in the coastal area of Zhejiang, and after the air battle, when cleaning the battlefield, the wreckage of the American AIM-9b Sidewinder missile was obtained, and it was analyzed, tested and researched and designed.

After learning of this incident, the former Soviet Union sent two groups of experts to China to obtain relevant technical information and some of the physical objects of the wreckage. Soon, on this basis, the former Soviet Union successfully trial-produced the K-13 missile, which was installed on the MiG-21.

In 1962, the Soviet Union provided technical data and samples of the MiG-21 and K-13 missiles to China for a fee. China began to copy the K-13 missile and named it "Thunderbolt" No. 2. In November 1964, the imitation of missiles was in full swing. From March to July 1967, a finalized test was carried out, and a total of 19 missiles were launched, and the test was successful. In November 1967, the Thunderbolt-2 missile was finalized and put into mass production.

After it was put into production, it became the only air-to-air missile that could be used by domestic air force fighters, and other projects are now developing slowly.

The J-8's original Thunderbolt-4 missile is still nowhere to be found, so it was forced to mount the Thunderbolt-2 missile, temporarily used as a weapon, because it has been operating on the J-7 for many years, so it was integrated into the J-8 without much effort.

The Thunderbolt-2 missile is composed of an infrared automatic seeker, a steering nacelle, a triggering and non-triggering fuze, a warhead, a rocket engine and a warframe. Canard aerodynamic layout, the warhead is a hemispherical blunt head, the projectile body is slender and cylindrical, two pairs of triangular rudder surfaces and two pairs of trapezoidal wings are in a cross-shaped configuration; The flight speed is Mach 2.2 and is mainly used to attack medium bombers and fighter-bombers.

If it is used in air combat, as long as the enemy plane maneuvers, it is easy to dodge, so it can only be effective against slow targets, and due to the defects of early missiles, it must also enter the tail and carry out tail chase attacks to be effective.

As a test pilot, Wang Yang has also launched this missile many times, and he knows the performance data of this missile, and it is not easy to kill the MiG-25, he must let the ground radar guide him to the correct airspace and launch the missile to have a chance to shoot down the opponent.

"001, attention, keep flying." There is constant guidance from the ground in the headphones.

"001 Roger." Wang Yang shouted over the radio.

His eyes searched the airspace around him.

Although there is a 204 radar in front of the nose, the effect of this radar is very close, and it is not even as far as his visual search, and now, he trusts his eyes more.

Closer, closer, in the distant sky, a bright spot appeared!

"Attention, 001, turn right, get ready to jump!" Voices came from the headphones.

At this time, there was an angle between his course and the opponent's course, and Wang Yang had to turn to the right before he could jump.

The J-8 fighter was slowly turning, and at this time it had already flown to 22,000 meters in the air, and his movements had to be cautious.

On the ground, everyone is waiting.

General Lin was in the tent under his command, constantly listening to the report from the radar station, and the two aircrew members were constantly moving the two planes and moving them around the map.

"Jump, jump now!"

After receiving the order, Wang Yang pushed the nose of the plane, and the fighter plane dived downward, and then pulled up.

The flight trajectory of the fighter plane is very similar to a cannonball fired into the sky.

The height continues to rise, rise!

The mech's body was also shaking as it climbed, and at this point, it had exceeded its design height and was struggling to continue climbing.

The MiG-25 behind is also roaring, because the MiG-25 is still climbing at this time, and the fuselage blocks the pilot's view, so he will not see a fighter flying below.

The two fighters were rapidly approaching, approaching, and when the huge black shadow passed overhead, Wang Yang knew that his opportunity had come!

Launch!

At this time, the fighter plane just reached the highest point of the jump, and at the moment when the plane was leveled, his fighter plane had jumped to an altitude of 25,000 meters, and the opponent was also at this altitude, and the opportunity was just right!

He pressed the launch button.

The Thunderbolt-2 missile immediately detached from the pylon, and then, Wang Yang saw nothing.

That's right, in his imagination, at this time he should have seen the tail of the missile dragging a puff of white smoke towards the enemy aircraft, but there was nothing in his field of vision!
