However, although Wang Bin, general Qiu and others did not interfere with the UAV, the UAV locked each other''s aircraft at least seven or eight times during the approach of the other''s fighters. Although the other''s fighters have tried their best to avoid tactics, they also want to lock the UAV as much as possible, However, although the other party has shown 12 skills, the UAV has only been locked by the other party three times, and the time of being locked by the other party is also very short.


    And these three times were locked. The other side did it only after the three fighters entered 30 kilometers away from the fighter. That is to say, if this was a real war, the three fighters had been shot down as early as 30, 50 or even 100 kilometers away. Fortunately, it is not a real war now.


    With the approach of the other fighter, Tiangong 001 UAV began to adjust its tactics. After all, both sides are about to enter the scope of close combat. As a UAV, due to the lack of emergency measures, it is obviously unable to have an advantage or even a great disadvantage in the process of close combat.


    Therefore, at this time, the UAV began to increase the horsepower of the engine, quickly flew to a higher altitude, and soon reached an altitude of more than 20000 meters. At the same time, the speed of the UAV has reached about Mach 1.5.


    However, although the UAV at this time has reached an altitude of 20000 meters, it is obvious that the other party does not want to give up and continues to fly here. After all, with the performance of modern fighters. At the same time, in terms of speed, it can basically reach the same speed as this UAV at this time.


    However, what surprised them was that while they continued to chase after the strange aircraft, the strange fighter did not stop rising because the altitude had reached 20000 meters, but continued to climb higher. After all, the height of the strange aircraft has reached 20000 meters, And now it''s still climbing.


    In other words, the maximum effective flight altitude of this strange fighter is definitely much higher than 20000 meters. At the same time, when the speed is released, what they show on the fighter radar has exceeded Mach 1.5 and will soon reach Mach 1.6. This aircraft is definitely a high-altitude and high-speed aircraft, and it is still an aircraft with certain stealth ability.


    Of course, while surprised, these fighters immediately reported the situation here to their superiors. However, at this time, their aircraft was very close to the altitude of 20000 meters. Unfortunately, this altitude was already the limit of the aircraft model they were flying, and there was no spare force to continue climbing, even if they could climb, They dare not, because once they continue to climb, their fighter will definitely lose control.


    So they could only watch the strange fighter plane that was less than ten kilometers away from them fly over their heads.


    Of course, they are not reconciled to this, but fortunately, at this time, a new command came from their base, allowing them to monitor the strange aircraft within the effective flight altitude and find ways to identify the identity of the aircraft and the type of fighter.


    In this regard, the pilots of these fighters were finally relieved. He was afraid that his superiors would order them to continue to climb up and chase each other. In that case, it would be absolutely very dangerous for them.


    So they immediately lowered their fighter to an altitude of about 15000 meters and began to track the strange fighter.


    However, to their surprise, at this time, the fighter plane did not descend because they fell, but continued to climb upward. It did not climb until the fighter plane reached an altitude of 25000 meters. At the same time, the speed of the unmanned aircraft had reached about Mach 2.0.


    In other words, at such a speed, even if they launch missiles, they can''t shoot down the other party. After all, at such a height, regardless of whether the missiles can reach, even if they can reach the missiles mounted on their fighters, they can''t catch up with the other party''s fighters. This makes them very frustrated. After all, there is nothing more oppressive than this.


    Of course, since Tiangong 001 UAV has flown to an altitude of 25000 meters at this time, it is already the limit of this UAV when it is fully loaded and full of oil.


    However, if all the big iron bars on the UAV are thrown away, the UAV can definitely climb again, and the speed will be faster. According to Wang Bin''s prediction, the fighter can at least reach the double three standard without load.


    After all, after being re optimized, the UAV has learned from the supersonic advantages of many Qiye fighters. In addition, the materials used by the three men have the fuselage strength, which is not comparable to that of Qiye. Therefore, reaching the double three standard will never have any impact on the fuselage.


    Of course, at this time, Wang Bin and others in the flight control center on the tower no longer pay attention to these foreign fighters, but continue to observe and record the flight test data of this Tiangong 001 fighter.


    At this time, the UAV flying at high altitude also continues to do various flight actions. After all, although several external aircraft have given up catching up, they are still monitoring the Tiangong 001 UAV. Even during the monitoring process, they continue to try to lock the fighter plane more than 25000 meters. For Tiangong 001 UAV, It is definitely a very good test plan. In fact, this is the main reason why Wang Bin and his Tiangong 001 fighter plane will be tested over the high seas of the East China Sea.


    However, Wang Bin, general Qiu and others know that although there is no good way for the other side''s fighters to take Tiangong 001 UAV, the other side''s fighters will definitely tell them the situation here, and their base will certainly come up with corresponding methods, They will never let Tiangong technology, this Tiangong 001 fighter, come and go freely.


    Sure enough, it wasn''t long before Wang Bin and his colleagues found that several looming targets were flying in the direction of Tiangong 001 in a place less than 130 kilometers away from nobody.


    At the same time, Wang Bin found that the electronic reconnaissance model of the fighter flying towards their UAV was very strange. At the same time, the flight altitude of the fighter reached 25000 meters, and the speed even exceeded Mach 2.5, which surprised Wang Bin and them.


    After all, in this world, there are few planes that can reach the double 2.5 standard or above. It''s just a few. Now the other party has dispatched a new fighter and is still a very strange stealth fighter, which surprised Wang Bin and them.
