On 5 July, the Chinese Air Force repeated its old trick and used fighter planes to cover bombers to bomb the US defense line. In order to prevent the Chinese Air Force from bombing the US defense line, the US Army Air Force had to face the Chinese Air Force. In the air battle that morning, the Chinese Air Force flew 83 FBs

'Hai Dongqing, fighter jets, the U.S. Air Force dispatched 120 'Hurricane, [type fighters. In the end, the Chinese Air Force lost 17 fighters, while the US Air Force lost 67 fighters.

In the afternoon, the Chinese Air Force continued to bomb the US Army's Rio Grande Line in order to attract US Army Air Force to come out for a decisive battle. Although it is known that the Chinese Air Force is using this method to deplete the strength of the US Army Aviation. But they can't help but be fooled, and they can't watch the bombers of the Chinese Air Force bombing the US defense line unscrupulously! Once their fortifications are destroyed by the Chinese Air Force, I am afraid that the Chinese Air Force will start to attack the American defense line. In the afternoon air battle, in addition to dispatching the remaining 56 fighters of the 7th Fighter Wing, the Chinese Air Force also dispatched one squadron each from the 1st Wing and the 6th Wing to assist in the battle, bringing the total number of sorties to 80. The US Army Air Corps has also been mobilizing fighters from other airfields to reinforce the vicinity of Laredo, and the number of US Army Air Corps fighters that took to the air on the afternoon of 5 October reached KC. After a bitter air battle, the Chinese Air Force lost 11 fighters, while the US Army Air Corps lost 52 fighters. That brings the total losses of both sides to 28 to 119 today. The exchange ratio is one to four!

On October 6, the Chinese Air Force continued its offensive against the U.S. military. The U.S. Army Air Corps, which was in a dilemma, had no choice but to passively face the battle. In today's battle, the Chinese Air Force lost 21 fighters, while the U.S. Air Force lost 108 fighters.

After three days of large-scale air battles, the Chinese Air Force has lost 86 fighters, while the US Army Air Force has lost 407 fighters, and the exchange ratio between the two sides has reached almost 1:5. Moreover, the U.S. Army Air Corps lost more than half of its fighters deployed on the Rio Grande Line. And the Chinese Air Force has 154 fighters. In this way, the air superiority over the Rio Grande Line has gradually tilted in favor of the Chinese Air Force. If the U.S. Army Air Force continues to fight, it is estimated that it will not be long before their fighters are depleted. This made Lieutenant General Kevinson, commander of the US Army Air Force, very anxious, and constantly sent telegrams to the War Department and the Army General Staff requesting support for more aircraft and pilots, otherwise, the sky of the Rio Grande Line would be occupied by Chinese fighters.

The large-scale offensive of the Chinese Air Force attracted the attention of the United States. Everyone had already expected that the Squadron's attack on the Rio Grande Line was about to begin. Once the Chinese Air Force has fully mastered air supremacy, it will probably be time for a major war to break out. To this end, the U.S. War Department and the Army General Staff quickly sent the latest 150 Hurricane fighters to the Rio Grande front to strengthen the front.

The U.S. Army Air Force can be replenished, as can the Chinese Air Force. Although the replenishment of the Chinese Air Force will span the entire Pacific Ocean, as early as when the Chinese Air Force decided to launch a large-scale attack on the US military, Marshal Zhao Bowen urged the General Staff and the Air Force Command to increase the replenishment of the North American battlefield. On 5 January, several transport ships carrying a large number of warplanes and pilots arrived in Puerto Vallarta. The fighters were loaded and unloaded and sent to the field airfield in Puerto Vallarta. Then there were pilots flying these planes directly to the front line. This time, in addition to sending more than 100 fighters and bombers to the four air wings in the North American theater to replenish the previous losses, the Chinese General Staff and the Air Force Command also transferred the 9th wing of the Air Force to the North American theater. This increased the number of wings of the Chinese Air Force in the North American theater to five. You must know that the Chinese Air Force has only formed a total of 10 wings. Eight of them are mixed fighter and bomber wings, and two are specialized fighter wings. The arrival of reinforcements and reinforcements greatly increased the strength of the Chinese Air Force in the North American theater, far surpassing that of the U.S. Army Air Force.

On July 7, the Chinese Air Force continued its attack on the US military. This time, the Chinese Air Force dispatched a total of 200 fighter jets, doubling the size of the previous aircraft. Although the U.S. Army Air Corps, which had been replenished, also dispatched 220 fighters to participate in this air battle, the final result was still disastrous. In the morning air battle, the Chinese Air Force lost 26 fighters, while the U.S. Air Force lost 143 fighters. Such huge losses once again caused the US Army Air Force, which had just been replenished, to suffer heavy losses again.

So much so that in the afternoon, when the Chinese Air Force launched another attack on the US military, the US Army Air Force chose to avoid the battle. Huge losses to make the US Army aviation! The air economy has lost the courage to continue fighting. If they continue to fight, they will lose all their fighters in a few days. At the same time, the huge casualties also caused fear in the hearts of the pilots of the U.S. Army Air Corps. Some pilots even refused to take to the skies to fight, or in the middle of an air battle, when they saw the Chinese Air Force fighters appearing, they immediately turned around and fled, and they did not have the courage to fight at all!

In addition, General Pershing arrived in Laredo at noon on 7 October. The dusty Admiral Pershing did not care about the fatigue of the journey, and immediately summoned Lieutenant General Kevinson, commander of the US Army Air Forces. On the way back to the defensive line, General Pershing kept receiving news of heavy losses in the army aviation, which made him worried. He had previously been at the White House to Theodore. President Roosevelt and other top U.S. officials assured him that he would hold the Rio Grande Line. But now it seems that the development of the battle situation has deviated greatly from what he expected!

"General Kevinson, how many planes do we have left to take to the skies now?" After seeing Admiral Kevinson, Admiral Pershing asked directly. He clearly remembered that the Rio Grande Line originally had more than 800 aircraft. And later the War Department allocated another 150 aircraft. This increased the number of fighters of the US Army Air Corps on the Rio Grande Line to more than nine hundred, which is already close to a thousand!

"General, we have four hundred fighters left. The losses in these days amounted to five hundred and fifty aircraft. In addition, there are a small number of fighters who cannot take to the air because of a malfunction! Lieutenant General Kevinson said with a bitter face. The U.S. Army Air Corps has paid a heavy price in the past few days of fighting. More than half of the planes and pilots have already been lost.

"Bastard! Then how many Chinese planes did we shoot down? Admiral Pershing asked.

"General, according to the number we get, the losses of the Chinese are probably only a little more than a hundred, not more than one hundred and ten!" Lieutenant General Kevinson replied. This exchange ratio is indeed a bit too embarrassing. He didn't know how to face it.

"A one-to-five exchange ratio? Raised by a son of a bitch, is this the gap between us and the Chinese? Admiral Pershing couldn't help but burst into a foul mouth.

"So, how many fighters do the Chinese still have to fight? Is there a way for us to maintain air supremacy over the Rio Grande Line? Admiral Pershing asked. This is the issue he is most concerned about, if the US Army Air Force loses air supremacy and can no longer defend the sky, then, it is foreseeable, the squadron will definitely launch a large-scale offensive.

"General, the Chinese Air Force has also been massively replenished. According to the information we have received, the Chinese Air Force has at least two hundred and fifty more fighters. The number of bombers is also definitely not less than this figure. If we can't get any more additions, we simply can't compete with the Chinese for air supremacy! Lieutenant General Kevinson returned. In a situation where the performance of the fighter and the quality of the pilots are completely incomparable with the Chinese Air Force, it is simply impossible to seize air supremacy with the Chinese Air Force. Originally, the US Army Aviation was also able to use its huge numerical superiority to maneuver with the Chinese Air Force. But now, the numerical superiority that the US Army Aviation has cannot be satisfied even by one to two. If you want to defeat the Chinese Air Force, it is more difficult than climbing to the sky. According to the air battles of the past few days, the US Army Air Force must have at least four times the numerical superiority to be able to compete with the Chinese Air Force.

"General, will we be able to get more additions? Also, when will we be able to get the 'Hurricane, Pie?' Lieutenant General Kevinson asked. If we could get a batch of more advanced 'Hurricane, Lute-type fighters, maybe the U.S. Army Air Corps would not be so wolf-like.

Admiral Pershing smiled bitterly, and then said: "The War Department and the Army Staff have already given us all the fighters that can be deployed. At least until next month, we don't want to get new fighters. As for the 'Hurricane, the Pipe fighter, although His Excellency the President has directly ordered the pace of development to be accelerated. However, the most optimistic estimate is that mass production will not be until the beginning of November. And if we want to get this kind of fighter, I'm afraid we will have to wait until the end of November! ”

Lieutenant General Kevinson's face was speechless, it was only October 7, and the US Army Air Corps had already lost most of its fighters. Based on the current losses, it is simply impossible for them to hold out until next month. By the time new fighters arrive at the front next month, I'm afraid the daylily will be cold. Once the Chinese have fully mastered air supremacy, I am afraid that they will immediately launch an attack on the Grande River defense line. And the US army, having lost air supremacy, can it hold out for a month in the face of the fierce attack of the squadron?
