Although it is said that the main purpose of Tiangong 001 UAV going to the South China Sea this time is to test this UAV, in fact, this Tiangong 001 UAV also came to the South China Sea with its own task, that is, to investigate the islands and reefs subordinate to China.


    At the same time, check whether there are ships outside China that carry out illegal operations in China''s territorial waters. After all, the South China Sea is different from other places. Even within the South China Sea, there are Chinese ships, aircraft and satellites in space that patrol frequently to safeguard China''s interests, but many people still ignore China''s warnings with luck.


    However, shortly after Wang Bin''s Tiangong 001 UAV entered the high seas of the South China Sea, radars from many countries detected the existence of the UAV. After all, although the UAV has been stealth designed, it is not a real stealth aircraft after all. It can''t be truly invisible at all.


    Therefore, we can only shorten the detection distance of the radar to a certain extent. For example, we could have detected the UAV 500 kilometers away, but after the stealth design, we can shorten the distance to within 300 kilometers.


    At the same time, the role of some strategic radars and those specialized in detecting stealth targets is also very limited. After all, the detection distance of strategic radars is often thousands of kilometers. Even if this UAV is stealth designed, the detection distance of these radars is halved, We can also find the existence of this UAV within one or two thousand kilometers, not to mention the huge place in the South China Sea.


    Therefore, Wang Bin and others are not surprised that these countries have found the existence of this UAV. At the same time, Wang Bin and others also know that since these countries have found the existence of this UAV, these countries will send corresponding fighters to monitor or even warn.


    Sure enough, after the radar of these countries found Wang Bin''s Tiangong technology UAV, the UAV detected that signals of non friendly aircraft appeared over many places in the South China Sea, and the place to which these signals flew was the direction of Wang Bin''s Tiangong 001 UAV.


    Wang Bin didn''t care about this, because Wang Bin didn''t care about the fighters of these countries. After all, this is over the high seas! Naturally, any country''s aircraft can fly here. The most important thing is that even if the fighters of these countries are hostile to their Tiangong 001 fighter, Wang Bin is not afraid. As long as the high-end flight of Wang Bin''s fighter reaches more than 23000 meters, it is impossible for the fighters of these countries to pose a threat to this UAV, After all, the industrial strength of these countries is basically not very good, let alone fighters.


    To put it mildly, even the first and second generation fighters, with the strength of these countries, may not be able to manufacture, let alone more advanced fighters.


    As for the fighters now used by these countries, naturally, they are imported from other countries, and the fighters sold to them naturally cannot be the most advanced fighters in the world. Even if they are placed in the third generation aircraft, their performance is just like that. After all, the fighters that can be sold to them are naturally castrated, Basically, the flight speed will not exceed Mach 1.5, and the flight altitude cannot exceed 20000 meters.


    As the fighters of these countries and Wang Bin''s UAV slowly approached, Wang Bin''s UAV also began to collect some information. At the same time, they also received the information sent by some national fighters on the public channel.


    They didn''t pay attention to these Wang Bin. After all, they don''t have to think about and know what the information sent by the fighters of these countries is. It just means that their UAV has entered their air defense identification zone, asked them to report their identity and leave, etc.


    At this time, general Qiu said to Pingping; "Tell them that this is a Chinese military aircraft patrolling over China''s exclusive economic waters, and let them immediately tell their identity, nationality and purpose."


    Although it is said that this is the exclusive economic zone of the South China Sea, it is also the high seas, so Wang Bin and his team are still unable to drive them away, but they can ask them to say their nationality, etc.


    In this regard, Yu Pingping immediately sent these information to through the UAV according to general Qiu''s words.


    However, after Pingping sent these information, it is obvious that among these foreign aircraft, many military aircraft have changed their course and flew in the direction they came.


    However, the military aircraft of two countries continued to fly in the direction of Wang Bin''s Tiangong 001 UAV, and soon entered the range of 100 kilometers away from the UAV. Even among the two fighters flying in the direction of Tiangong 001 unmanned, there was another one, which had nothing to do with the South China Sea.


    There is no good way for Wang Bin to do this. Let alone say that the times are different now. Wang Bin and they can''t shoot down each other directly. Even if they can, there is no way to do it according to the current situation of Wang Bin''s UAV. After all, there are no weapons on the UAV. In addition to being able to investigate, they have no combat ability at all.


    At this time, the fighters of the two countries have entered the range of 100 kilometers from the UAV.


    Therefore, at this time, the UAV also began to rise in height and speed.


    After all, if they continue to fly at the previous speed and altitude, Wang Bin and others are not afraid of what the fighters of these countries will do to Wang Bin''s Tiangong 001. After all, the Chinese military aircraft and warships in this sea area are not only their Tiangong 001 UAV, but if they do so, when these fighters approach this UAV, They will certainly detect a lot of data about this UAV.


    The most important thing is that we are not afraid of ten thousand just in case. After all, some countries have poor capabilities, but their ambitions are not small, not to mention some people who have nothing to do with the South China Sea.


    However, when the altitude of the UAV reaches 23000 meters and the speed reaches Mach 1.8, it will no longer rise in altitude and speed.


    Because after reaching this altitude and speed, the fighters of these countries have no good way to Tiangong 001 UAV, and even whether the air-to-air missiles of these countries can reach this altitude is not certain.


    Sure enough, after the height and speed of Tiangong 001 UAV were improved, the fighters of these countries were stupid, because they didn''t expect that this UAV belonging to China would be so advanced that it could fly above 20000 meters, and even its speed reached this level, which has exceeded the speed and height limit of the fighter they drove.
