The development of hot air balloons can be said to be the beginning of the replication of sky technology through the crowd, to say that at this time it is obviously impossible to make such a tall thing as an airplane, what is an airplane, and the current scientific level alone cannot solve the problem of materials.

The hot air balloon is much simpler, so the Commission of Science and Technology directly gave up the big aircraft project, or the hot air balloon, this thing is a little less difficult, and it is relatively easy to mass-produce.

This plan began in 1643, and it took a full year at the beginning of today, from the establishment of the project to the construction, it can be said that it has been very fast, and it is very rare to put it into mass production now.

Even local Australians have never seen a hot air balloon, this thing has always been highly classified, and it is no wonder that Yu Shan does not know.

As for why Qiao Yan knew, he had also heard He Yu mention it to him, and asked him to keep it secret, which was a highly military secret.

It has only been half a year since the establishment of the Australian Air Force, and it has only taken more than ten or twenty times from training to the implementation and simulation of actual air launch missions.

Therefore, this is their first official mission.

The air force unit that had set out from the mainland a month and a half ago had already arrived at Dayuan Island by boat, where it conducted secret training, and only after completing several airdrop missions was it transferred to Guangzhou to carry out the mission.

Although the air force unit is not as large in number as the other two major units, and it is not even comparable to the garrison unit, it can definitely be regarded as a unit to which the state attaches the most importance.

In the future, the air force will play a tremendous role on the battlefield, and even those who are military blind will know that mastering air supremacy is actually equivalent to mastering the dominance of war.

However, it is certainly not so powerful now, and the main role of the air force at present is to airdrop supplies and drop incendiary bombs above enemy troops.

In order for Australia to win this war, it will actually need the air force to join the battle to help the two Guangxi control the area south of the Yangtze River.

According to the operational plan drawn up by the Ministry of National Defense, the Air Force will eventually be allowed to drop bombs and incendiary bombs over enemy forces.

This plan was initially opposed by some people, after all, because it would cause casualties to ancient buildings and other people. But for now, it is very necessary, and if these things are taken into account, then the Australian battle plan may fail.

It is very clear what the defeat means, and if the south of the Yangtze River is not recovered, it will lose the largest space for confrontation with the north in the future.

Although the two Guangxi and Guangxi can develop best in the industrial field, they do not have the support of a large market, and in fact, the industries that eventually develop are also commanded to make the small scale not enough to support the completion of the entire unified operation.

To be able to recover the territory south of the Yangtze River is the greatest effort made by Australia, and if it wants to completely drive the Manchus out of the Guanwai, it can almost be said that it is a fool's dream, and when the standing army does not reach 200,000, it is simply not enough to support such a big war.

The supreme commander of the Air Force is Su Yu, who has flying experience. Su Yu's age can be said to be the youngest, Su Yu, who is only 26 years old this year, used to be in the flight class of the aviation school, and he has experience in air flying, and he is the only one among more than 500 people who has this experience.

Su Yu's military salary is a colonel, and although his position is that of the commander-in-chief of the Air Force, after all, he has never participated in a battle, and he will directly come up to ask the Lieutenant General what the people in the army and navy think, even if the high-level has high hopes for the Air Force, they must respect the mood of the two main branches of the country. Otherwise, with their personalities, they may really make a direct fuss.

Of course, Su Yu, this young man, is also very self-aware, knowing how many pounds and taels he has, and how capable he is. After all, he has no combat experience at all, and it is not a good thing to be promoted to a senior general without any military merits.

The rain has stopped in Shaoguan, and it is inside the city of Shaoguan. In an area under martial law, air force units are in full swing to launch a hot air balloon.

They are going to drop supplies to the troops that have broken through, and this delivery task is very important. If it is not successful or the launch is wrong, then it is very likely that the first battalion of Qiao Xi will not be able to return behind enemy lines, and the battle plan formulated by the Ministry of Defense will also be affected.

In this case, in fact, Su Yu's pressure is also very great, as the commander-in-chief of the Air Force, he has to personally participate in this battle, which is not only about the outcome of the victory on the battlefield, but also about the development of the future Air Force.

The Ministry of National Defense spends so much on the military every year, and in the past, the navy and the army were divided, but now they must come up with results if they want money. Even if the senior management wants to give themselves, they must have enough results to convince everyone, otherwise it will not work in the current situation.

For the future of the Air Force, in order for this war to be successfully completed, Su Yu also fights, he can't fight if he doesn't fight, and if he doesn't fight, it means that he has given up the development of the Air Force, so he will definitely become the most ineffective commander in the history of the Australian Air Force.

"The boys of the Air Force are doing your best today, do you have the confidence to complete the task?"

Su Yu stood on a high platform and held a mobilization meeting in front of the station, which is an unwritten rule in the Australian army.

After all, they are soldiers to have a good future, if it were not for the high subsidy offered by the Air Force, it is estimated that many people would not join the Air Force, after all, this is flying in the sky.

The sky is not underground and on the ship, the danger factor is too high, of course, there are some people who join the air force with the magical thing of being able to fly into the sky, Su Yu has high hopes for his team, which is currently less than three hundred people, and he hopes that this force can play a huge role on the battlefield.

And from the very beginning, he was very sure of the military order, if he didn't complete it, he would have to be disarmed and returned to the field.

"Guarantee the completion of the mission, please rest assured, commander."

The answers in unison finally gave Su Yu some confidence.

Then the team members began to parachute hot air balloon bamboo baskets, each hot air balloon loaded with not many supplies, which is also a very difficult task in transportation.

When the extra-large Kong Ming lanterns were raised from the city of Shaoguan, both outside the city and inside the city had their own opinions on these big balls, especially the Eight Banners Army, who were pointing at the hot air above their heads and commenting on what they didn't know was that these hot air balloons would bring them huge trouble in the near future, and it could even be said that they would cause them a devastating blow.
