According to huanqiu.com, the “Shoulder to Shoulder 22” joint military exercise between the United States and the Philippines is being held in the waters of Southeast Asia. Nearly 9,000 military personnel from both sides are involved in the exercise, which has attracted high attention from all sides.The U.S. military is known to have used high-altitude balloons as part of its training in shoulder to Shoulder 22.Ads-b signals indicate that at least two Raven Aerostar high-altitude sounding balloons were used in the exercise, and one of them is currently flying over the Luzon Strait.These high-altitude balloons can monitor the surroundings more accurately than aircraft and satellites in earth orbit, and obtain clearer images at a higher resolution.According to a press release, Raven Aerostar has previously purchased patents for Google’s Loon Network of balloons, which have led to new high-altitude balloon science experiments with the U.S. Department of Defense and numerous flight tests in recent years.Through test and data analysis, the pentagon believes high overpressure balloon can serve as a kind of infrastructure, are being used on the height of the atmosphere in the stratosphere, the U.S. can use the balloon, carrying all kinds of payload as high altitude communications node, undertake the task information relay, to other reconnaissance platforms and weapons and equipment to provide fire target direction.Back in September, the Norwegian military held exercise Thundercloud, in which Raven Aerostar launched a high-altitude balloon that successfully detected a simulated target in the Norwegian sea in collaboration with Norway.The mission proved the practical feasibility of high-altitude balloons, which the U.S. military would not dare to use if they only worked in domestic tests and failed in other countries.Norway is a member of NATO. It is the only one of the three major Nordic countries — Sweden, Finland and Norway — to join NATO. The country has a relatively tense relationship with Russia, and is one of the countries with a relatively tough attitude towards Russia in NATO.After undergoing rigorous testing in Norway, the U.S. Department of Defense Innovation decided in November to award Raven Aerostar a contract to produce high-altitude balloons for the Defense Department to help the U.S. military enhance its high-altitude surveillance capabilities.High-altitude balloons are cheaper to produce than manned reconnaissance planes and low-Earth orbit reconnaissance satellites, but they work well in practice.Compared with traditional satellites and reconnaissance planes, high-altitude balloons are cheaper, but they can cruise over a target area for a long time.Because the flight status of the high-altitude exploration balloon is particularly stable, its carrying equipment is also more prominent, so it can achieve higher resolution in the shooting of the photo.The advanced high-altitude exploration balloon has a resolution of about 0.5cm, which means it can identify targets up to 0.5cm in size on the ground.High-altitude balloon is not a new thing, he is an old equipment, its predecessor is the airship and hot air balloon, has a hundred years of development history.This kind of balloon is also called “high altitude science balloon”, especially refers to the unpowered aerostat that flies in the stratosphere. Because the atmospheric airflow in the stratosphere is stable, it is very conducive to the cruising of the balloon. Therefore, this kind of equipment is widely used in the stratosphere.It can reach an altitude of 40-50km.In addition to high-altitude physics experiments, it can also be used in the military field.
