Changxing Island (Dorak Island) Air Base.

This largest air base in Donghui Zhennan Province has been operating at full load since its establishment, and a large number of fighter planes take off and land every day. In particular, since Air Force Commander Gao Zhihang put forward the training requirement of "taking actual combat as the purpose," under the training of the Luftwaffe advisory group, the roar of fighter planes' piston engines has always resounded over the airfield, whether it is rainy, rainy, or snowy, day or night.

All-weather, all-weather combat training is the training standard repeatedly emphasized by the Third Division of the Donghui Air Force. The officers and men of the division have consistently complied with the strict requirements set forth by the Air Force Command and the Division Headquarters as well as the Luftwaffe Advisory Group, and have vigorously grasped training, strengthened the quality of pilots, and enhanced their ground support capabilities. As a result of all these measures, the overall combat effectiveness of the 3rd Air Force Division is always challenging the status of the 1st Air Force Division, which is personally commanded by Air Force Commander Gao Zhihang.

The Luftwaffe advisory group was composed of Hitler's outstanding pilots selected from the Luftwaffe at the request of Cheng Gong. Among them are the now unknown Molders, Adolf Garand, Helmut Vick, Rishi Terhofen, Wöllner Molders, Hans Joachim Marseilleu, Emil Lange, Walter Novotny, Heinz Wolfgang Schnaufer, Günter Lütso, Lütso Gerhard Balkhorn, Johannes Steinhoff, Walter Krupinsky, Heinz Bell, Wilhelm Hergert, Erich Hartmann, Gerhard Balkhorn, Hans Ulrich Rudel and other famous German ace pilots of World War II.

The establishment of a large air base on Changxing Island (Dorak Island), which is less than 300 kilometers away from the 141st parallel, it is not difficult for a discerning person with a little military acumen to see that sooner or later the Donghui Kingdom and Australia will have a war.

Although Cheng Gong, the king of Donghui, claimed to be a peaceful person who loved world peace, no one believed that Yi Donghui's strength would honestly defend such a palm-sized territory as the former Dutch New Guinea. Because this is the sorrow of a weak country with a strong neighbor next to it.

Although Australia, with the support of Britain, France, the United States, and other countries, raced against time to build the "Marauch Line" with the intention of turning Australian New Guinea into a bridgehead and a "super arsenal" to counterbalance Donghui's expansion, no matter how strictly the Australian Air Force defended it, it could not prevent Donghui Air Force fighters from coming and going freely in the skies of Australian New Guinea Island.

In particular, after the 3rd Division of the Donghui Air Force began to be equipped with P51 Mustang fighters, the airspace of the 3rd Air Division's daily training flights was unscrupulously extended to Australia's airspace.

Unlike the 1st Air Division stationed on Paradise Island, the 3rd Air Division stationed in Zhennan Province and the 2nd Air Division in Dingnan Province worked closely with the Luftwaffe from the beginning of their formation. To this end, Cheng Gong specially equipped the 2nd Air Division and the 3rd Air Division with C54 "Air Giant" transport aircraft, F8F "Panda" fighter, F4U "Corsair" multi-role fighter, AD-1 "Sky Raider" attack/dive/lightning strike aircraft, and P38 "Twin Demon" high-altitude and high-speed interceptor.

Logically, the Luftwaffe directly began a large-scale copycat after absorbing and digesting all the technologies contained in the four main models of the Donghui Air Force.

Seven German aircraft manufacturers, including Junkers, Henkel, Messerschmitt, Dornier, Focke-Wolff, Henschel, and Arado, formed a joint stock company with Donghui National Airlines to invest in the construction of the world's largest Donghui Airbus Aviation Holding Group Company in Zhennan Province.

Donghui Airbus Holding Group not only produces C54, F8F, F4U, AD-1, P38 and other military aircraft, but also produces DC-6 civil airliners.

The P51 "Mustang" fighter, which belongs to the latest research and development achievements of the Donghui Airbus Control and Investment Group, has just been finalized, and it has received two large orders for 1,500 aircraft from the Luftwaffe and 1,200 aircraft from the Japanese Air Force Command.

In response to the blatant "infringement" of Donghui Airbus Holding Group, Douglas Company, Lockheed Company, and Boeing Company of the United States sent a strong team of lawyers to accuse Donghui Airbus Holding Group of embezzlement and theft of their design patents. However, Donghui Airbus Holding Group's responding lawyer group publicly refuted it, claiming that the C54 and DC-6 did not infringe Douglas's C47 and DC-3 patents at all, because the registered utility new patents of C54 and DC-6, including engine technology, are far stronger than the original design patents of C47 and DC-3.

The unrelenting group of U.S. lawyers turned their attention to the P38 "Twin Demon" interceptor produced by Donghui Airbus Holding Group, claiming that it was a patent belonging to Lockheed Company. As a result, the lawyers of Donghui Airbus Holding Group proposed that Lock-Heed compete their XP-38 against Donghui's P38 "twin demon", and whoever had poor aircraft performance was infringing on the other's technology patents. The reason is simple, whoever has poor performance is a copycat. Because, there has never been a precedent in this world for imitations to surpass the original products.

During this period, the United States itself was the world's largest "copycat country". The industrial development of the United States was developed on the basis of constantly copying European industrial products. When the lawyers of Donghui Airbus Holding Group seized on the weakness of the United States and cited scriptures and repeatedly listed one piece of evidence, the American company lost the case tragically.

With the increasing number of DC-6 civil airliners, C54 military transport aircraft, F8F "Panda" fighters, F4U "Corsair" fighters, AD-1 "Sky Raiders" attack/dive/lightning strike aircraft, P38 "Double Demon" interceptors, and P51 "Mustang" fighters manufactured by Donghui Airbus Holding Group, the strength of the Luftwaffe, Italian Air Force and Japanese Army/Navy Aviation is also increasing.

When Donghui Airbus Holding Investment Group began to add branches in Germany, Italy and Japan, the United Kingdom and France could not sit still.

In the global civil aviation aircraft market, the DC-6 produced by Donghui Airbus almost monopolizes the entire regional and trunk airliners. The market shock caused by this technical barrier has made the allied bloc led by Britain, France and the United States further accelerate the pace of arming Australia.

The governments of Britain, France, and the United States, while constantly exerting pressure on domestic aircraft manufacturers to develop more advanced and powerful fighter jets as soon as possible, have also submitted applications for advanced fighter technology transfer to the Donghui government through Lawrence Rockefeller, Hughes Field, and Andrew Luton.

It's a pity that the Donghui Cabinet, which has existed in name only, can't contact Cheng Gong at all now.

Before you know it, the calendar has flipped to June 1, 1939.

"Woo woo woo woo ......" piercing sirens echoed over Changxing Island Air Base.

Hans Joachim Marseilleu, captain of the 1st Squadron of the 7th Combat Aviation Regiment of the 3rd Division of the Donghui Air Force, suddenly jumped up from his single bed, rushed out of the pilot's dormitory with his flight helmet in his hand, and ran as fast as he could to the direction where the hangar was located.

"Level 1 Alert! Level 1 Alert! "The constant sound of the loudspeaker was telling all the pilots who rushed to the hangar and tarmac that this was not a drill, but an urgent combat mission.
