Looking down from the sky, the current island of Oahu resembles the surface of the moon, full of huge deep holes with potholes, so many and dense that even people with dense phobia can faint.

Even when flying at an altitude of 4,000 meters with the FW190 Thunderbolt fighter-bomber, pilot Matsudane did not like to look down, because the ugly appearance of Oahu was really unsightly. After several months of continuous bombing, nearly 2,000 rounds of 10-ton and five-heavy super aerial bombs have smashed this pearl of the Pacific Ocean into an ugly pockmarked face.

During months of bombing, the island's dense tropical jungle was also completely destroyed. In order to destroy the trees on the island, the Japanese sometimes sent out heavy bombers to drop a large number of incendiary bows into the trees on the island. Now when you look down from the sky, you can see not much "greenery", but more of the reflection of the dotted water surface.

Hawaii is located in the middle of the Pacific Ocean, and the island is rainy. The reflections that made Matsuda root dense phobia came from the huge crater smashed by the 10.5-ton bomb. The potholes were too deep, too big, and too many for the U.S. forces on the island to fill during the war. As soon as it rains, these huge pits automatically become rainwater collectors, which are collected for months, and some low-lying pits are even filled with rainwater and become small lakes the size of natural swimming pools. The artificial lakes blown up by these aerial bombs are like mirrors in the sunlight, reflecting white light to the sky.

The Sky Thunder fighter-bombers, with two auxiliary fuel tanks hanging under their bellies, were carrying out a pressurized cruise flight over Oahu, and their mission was only one: to suppress the US airfield on Oahu, and as soon as the planes on Oahu wanted to take off and attack, they would take advantage of the altitude advantage and immediately dive down. Then the four 20-mm cannons and two 12.7 machine guns equipped on board exploded the climbing US plane in the air.

Matsuda was part of the Nagoya Flying Squadron of the Japan Army Airlines, and he flew the TA190 Thunderbolt, an air-cooled fighter currently equipped with the Luftwaffe. It was originally called the FW190, but it was renamed TA190 in order to distinguish it from the FW190TF used by the Navy and to thank Dr. Tanck for his contribution to the German Air Force.

Although all used to be called FW190. But the Navy and the Army are essentially two different fighters. And in terms of appearance, anyone who sees them will think that they are not the same kind of aircraft.

The FW190TF used in the Navy, T stands for the Navy type, and F stands for the Attack type. The ancestor of the development of this German fighter can be traced back to the FW90, which became famous during China's air war in 1935. At the beginning of the design of this aircraft, its aerodynamic shape was a complete copycat of the idea that is now being equipped with the F4U Corsair fighter of the US Navy. Even the disadvantages are exactly the same.

According to the German Navy's idea of military construction, in order to facilitate the maintenance of aircraft on aircraft carriers, the FW190T series was developed in order to "equip aircraft carriers with only one type of aircraft". The requirement that this aircraft be capable of air combat, be able to accurately dive and bomb, and even be able to drop mines -- the third requirement was finally cancelled due to the technical limitations of the time.

To meet these requirements. The best means, and the best historical references. It was the development of a fighter with an inverted seagull wing like the F4U Corsair.

In terms of appearance, FW190TF has a pair of "distinctive" and extremely beautiful inverted seagull-shaped wings, which look wide and large, and are very conspicuous. The flying shape of this aircraft. At the beginning of the design, Dr. Tan Ke was influenced by Lin Han and directly copied the aerodynamic shape of the F4U. The U.S. Navy, which is receiving the F4U, has no idea that for this reason the FW190TF looks almost exactly the same as the F4U Corsair. In the future Pacific War. For this reason, there will be a large number of unlucky Corsair fighter pilots, who will be mistakenly shot by their rookie anti-aircraft gunners as enemy fighters after returning from the air battle.

The advantage of this aircraft is that it is excellent in combat and excellent in dive bombing performance - second only to the professional dive bomber JU87. The disadvantage is that it is not easy to pilot, and it is difficult for novice pilots to control, which is a sharp weapon for elite pilots and a nightmare for rookie pilots.

According to the German Navy's concept of building and fighting, the navy is the only branch of the world that can defeat a war in a few hours, so the weapons of naval aviation must be high-precision, and it is not a problem to be difficult to pilot, because the pilots of the navy are elite, and the decisive battles they can really participate in are two or three battles.

Under the leadership of Li Huamei, as soon as the FW190T entered the Japanese Combined Fleet, its excellent performance immediately compared with the old 99 ship explosion and other aircraft. With the addition of a large number of German planes to the Japanese Navy, by December 1942, the Japanese Navy's aircraft carriers and air carriers, professional dive bombers had all been eliminated, and now there were only three types of aircraft on the Japanese combat aircraft carriers, in addition to the Caiyun reconnaissance planes, the Swift responsible for medium and high altitude air combat, the Sky Mine responsible for medium and low altitude air combat, and the torpedo attack aircraft.

FW190T, debuted in 1940, has been in service in the German Navy for nearly three years, after many improvements, although there is still a problem of not being friendly enough to newcomers, but all kinds of problems that will have flight accidents are solved, it is a very mature fighter.

The TA190 used by the Army Aviation, that is, the Thunderbolt fighter, is basically the same as the FW190 of the same name in history, and the design idea also reflects Tan Kebo's own understanding of air combat: to design an easy-to-pilot "War Horse" fighter, rather than the "Mustang" like the Navy.

In terms of the army aviation or air force, once an air battle on land starts with an enemy country, it is often a long and arduous long-term war, and the attrition of pilots is also exhausted, and in many cases, a large number of rookie pilots are often sent to the battlefield to serve as cannon fodder. At this time, the aircraft is easy to pilot, and the advantages of being "friendly" to pilots are reflected here.

The Japanese Army Airlines, which took the elite route, also had the opportunity to take to the skies in a FW190TF land-based version, but because the Army Airlines was unwilling to accept the aircraft used by the Navy, it finally chose the TA190, which was cheaper.

The TA190 was named Thunderbolt in the Japanese Army Aviation as a replacement for the Flying Fighter before it was delayed from entering service. After the start of the Pacific War, the German side dumped as many as 600 planes at the "price of cabbage" on the Japanese side in one go. In order to be able to rush to deliver the goods in a short time, the German side even directly picked up the cargo from the aircraft in active service with the Air Force.

The reason why the German side is so enthusiastic is because the Luftwaffe is about to enter the era of 2000 horsepower engines, and the TA190 has a maximum horsepower of only 1800, which is the upper limit of the BMW 801 power for it, and the potential of this type of engine has been exhausted. Selling to the Japanese at a very cheap price is also conducive to the upgrading of the country's air force.

One of the biggest advantages of being a traverser is that you can know how long the enemy's new weapons will be in service. As a veteran military fan who spends his days talking to people on forums, Lin Han is very aware of the service time of various types of advanced fighter jets in the United States. The time when the Japanese lost the performance advantage of fighter aircraft in the Pacific Ocean was in December 1942, when the Corsair fighter entered service.

In order to better trap the Americans, he asked Li Huamei to encourage the Japanese navy and army to speed up the updating of fighter planes, and on the other hand, he wanted to collude with his concubine Hannah to sell fighter planes with still excellent performance to Japan at a price of half selling and half giving away.

Although the maximum horsepower of the air-cooled engine does not exceed 1,800, the two 190 series fighters developed by Dr. Tan Ke are not as powerful as the eighteen-cylinder RE2800 engines on the pirate F4U, and the upgrade potential is endless. But F4U is only a new product now, the performance is not perfect, and there are many problems. Moreover, the Corsair was equipped with a two-stage pressurization, which not only ensured its excellent high-altitude performance, but sacrificed a certain amount of performance at medium and low altitudes, and the two aircraft designed by Dr. Tan Ke were clearly defined: they were medium- and low-altitude fighters specialized in the middle of the industry -- naval planes needed to carry out maritime search and patrol missions, and the usual flight altitude was less than 5,000 meters.

In the way of conceiving the construction of the Air Force, Lin Han and Hannah proceeded from their own national conditions, and in terms of fighter performance, they took the route of matching high and low: air-cooled fighters, considering the characteristics of their fighting, did not install two-stage pressurization equipment, and concentrated on carrying out combat missions at medium and low altitudes. As for air combat at altitudes of more than 7,000 meters, it was carried out by a two-stage pressurized liquid-cooled fighter jet.

As for the tall exhaust gas turbocharged fighter, although it is the king of piston fighters with an altitude of more than 8,000 meters, neither Germany nor Japan can afford to play this thing, and only the Americans with deep pockets can afford to burn it. In air combat at an altitude of more than 8,000 meters, Lin Han and Hannah both bet on jet fighters.

After Li Huamei successfully entered the Japanese undercover service, he developed the line for the Japanese Air Force, and also borrowed this idea from the Luftwaffe.

A total of eight Japanese fighter jets are now on alert and suppressive patrols over Oahu.

Four Thunderbolt fighters, which are suitable for medium- and low-altitude air combat, are cruising at an altitude of 4,000 meters, and as long as the US planes on the ground want to take off forcefully, they will immediately dive down and shoot them down in the process of climbing.

In air combat, altitude is energy, altitude is speed, and even if the performance of a Japanese aircraft with a temporary altitude advantage is not as good as that of a plane on the ground, it will also take advantage of it in air combat in this situation of taking advantage of the "time of day."
