Then Hartmann aimed at the next one, but after the fire started, he was stunned. It was not because he easily and comfortably broke through the 100 aircraft mark, but because he only shot a few points, the P51 on the opposite side actually exploded into a fireball and fell from the air. This scene made him stunned? After thinking carefully, he suddenly contacted what the aerospace engineer said when introducing the performance of the aircraft to him at night: the do-412 is equipped with the latest air combat artifact mg-213, which is so powerful that you will definitely have a deep understanding at that time.

Hartman only knew that both mg213 and mg151 were 20mm machine guns. He intuition believed that the former was a rotary gun, so the firing speed was fast and powerful, but he ignored the difference in ammunition. Although both used ammunition with a diameter of 20mm, the former used ammunition of 20?mmx?146?mm, while the latter was 20?mmx82?mm. How could the power be the same? Because of this, the do-412 originally had to be equipped with 4 mg-213, but because the engine power was limited, it could not bear such heavy weapons. In the end, the machine was turned into a combination of 2 mg213 + 2 mg151. Even if the engineers still thought it was heavy, they hoped to adjust it to a combination of 4 mg151, but Mr. Donier refused to agree.

Not only did Donier refuse to agree, but even Dr. Tan Ke copied the configuration. The f-190a8a9 series that were shipped later were all 2-door mg213+2-door mg151. Is there any aircraft that uses all 4-door mg213? Of course, there is a answer. One is the me-262 with a significant increase in thrust after replacing the engine, and the other is the 8 ta-152s that the Air Force has verified this time.

The Ta-152 has a code name in the Air Force system called the Ultimate Propeller Fighter. Unlike in history, Dr. Tan Ke, who has priority and guaranteed supply, did not use the 213 liquid-cooled engine this time, but directly used 2,300 horsepower, a db603 liquid-cooled engine with two stages of three-speed supercharger and an L-type intercooler. The maximum speed can easily reach 727 kilometers per hour. If you use the two drug-taking systems of mw50+gm1, the speed can be increased to 760 kilometers per hour, and the practical ceiling is 14,000 meters. The fastest speed, the strongest firepower, and the highest altitude make it a pet for the Air Force bosses as soon as it was born. It is described as "perfect!"

Of course, Tan Ke himself dare not say the perfect sentence because he met his opponent. There were two versions of ta-152 initially, one was ta-152c and the other was ta-152h. The former mainly focused on medium and low altitudes below 7,000 meters, and the latter mainly focused on medium and high altitudes above 9,000 meters. The most significant difference between the two is that the h-type is more than 2 meters longer than the c-type wingspan, so the high altitudes are more effective. His old friend Donier was also unwilling to accept that the do-412 can only be used in medium and low altitudes, and also secretly developed the do-412h type, trying to get a share in the field of high-altitude interception.

The two sides often compete and study. The results show that at medium and low altitudes, especially at medium and low altitudes below 6,000 meters, although the absolute speed of the Ta-152 is faster than the do-412 (of course it is faster than p51p47, etc.), its maneuverability and flexibility are not as good as the do-412. In the field of high altitudes, the do-412h model developed with great effort is not an opponent's liquid-cooled engine with natural advantages at high altitudes, and this is considered that the do-412 cannot be

The factor of getting 2300 horsepower air-cooled engines is that if the current 2000 horsepower 801 engine is just the current, the gap between them is even greater. In the end, the two sides reached a consensus that the do-412 can perfectly replace the f-190 and b-219, and the ta-152 can perfectly replace the f-190 and b-109gk (this is the last improved series of Messer Schmidt's 109 series, focusing on high-altitude interception).

This unanimous viewpoint unabashedly exaggerates the two's ambitions to completely drive Messer Schmitt out of the fighter market! Do-412 and Ta-152 join forces without any of Messer Schmitt in the propeller field, and the successful test flight of the single-machine Ta-183 means that the jet field will undergo earth-shaking changes in the next year. After hearing the news, Dr. Messer Schmitt was angry and anxious. On the one hand, the company's main b-319 (fire wind modification) is not yet in the current climate. On the other hand, the inherent weakness of the me-262's dual-machine cannot be adjusted, so he can only hope to update the generation. He was seriously ill because of this. However, Jiro Horikoshi, who was in charge of the 319 project, advised him not to worry, everything is not yet concluded...

The pilots didn't care about the grievances and grievances behind these big companies. They just wanted to fight the plane. At the time of Hartmann's fire, the other combat aircraft were also firing fiercely and continuously. The targets of attack were P51s and transport aircraft. Although the number of P51s escorted was twice that of German fighters, the number advantage did not equal tactical advantages. In particular, the F-190a8 that was transferred this time were the most experienced veterans in dealing with four-engine bombers on Azore Island. Maschel transferred them to deal with the endless US heavy bombers, because they were always unable to do so when fighting with B-219. Unexpectedly, they encountered a transport aircraft that was weaker than bombers. It was basically equivalent to a tiger entering a flock of sheep and harvesting them freely.

I saw an F-190 pounce at the C-54 Air King close range. Although the US machine gunner fired violently, the German pilot ignored it and kept firing at the opponent's wing part. The 20mm thin shell bomb was beaten like a storm. In less than 5 seconds, the wing of the aircraft was interrupted from the wing root. The ending can be imagined. The aircraft took people and blew down! Some aircraft aimed at the huge vertical tail of the transport plane. These were all veterans who were accustomed to bird shooting. They knew that the US aircraft had thick skin and rough flesh, and they could not do anything to them when they opened several holes at ordinary locations, but the wing roots and vertical tail were fatal. As long as they hit, there was no reason to survive. The mg213 factory exacerbated this panic. As long as they hit 8-9 rounds, a 4-round bomber or transport plane would be finished.

Of course, mg213 is not the most powerful weapon for transport aircraft. The most crazy thing is the M rocket carried by the F-190. The gorgeous brilliance flying in the sky made people's scalp tingle. All paratroopers who have landed and are landing in the air dare not look up. This kind of rocket can blow down a huge transport aircraft in just one shot. If a paratrooper is unfortunately in the explosion range, it will be kept as a piece of black charcoal! In just 2 minutes, four transport aircraft that fled desperately were fought by the German army.

The plane easily caught up, and then beat it up into a fireball. Fortunately, the German army still has a gentlemanly demeanor. No matter the crew or paratroopers, the pilots knew that they would inevitably have the day to jump. If they killed the opponents of the skydiving today, they might be covered with machine gun holes when they parachuted tomorrow. This tacit understanding also extends to attacking the ship. It is natural to shoot at the ship, but there is no need for the officers and soldiers who have lost their ability to resist after the ship sinking.

When the German army launched attacks with endless powerful weapons, their opponents, the P-51b fighter pilots of the US Army Airlines P-51b fighter can only live with 4 or 6 12.7mm machine guns. What's even more tragic is that due to the angle design of the ammunition chain, the P51 is designed to solve the problem of this ammunition problem. Of course, this is not that the American ordnance designers do not know how to install cannons on aircraft, nor that the United States does not have machine cannons. The United States has an/n2 cannons, and the United Kingdom also has the famous machine cannon.

Most US military aircraft do not install machine guns, which is actually a comprehensive system problem. On the one hand, US fighters mainly competed with Zero in the early stages of the Pacific battlefield. With the fragile characteristics of Japan, they were more than enough to deal with the 12.7mm machine gun, and the effect was good. Therefore, they instinctively believed that the 12.7mm Browning machine gun was invincible in the world; on the other hand, most of the US pilots were novices. If they were equipped with machine guns, they were afraid that they would hold the launch button and not put them on, and they would be able to pour out all the ammunition in less than half a minute. If it was a machine gun bullet, it would have enough launch and firepower coverage time.

This theory began to fail after 1943. Firstly, because the US military encountered more and more German aircraft, not to mention those attack aircraft and bombers, the defense of the B-219 developed on the basis of zero war is much stronger than that of zero war, not to mention the thick meat machine like the F-190; secondly, Japan's HNA is gradually replacing equipment, and a large number of B-109219 and F-190 began to be introduced. Japanese pilots are not stupid, of course, know which aircraft is easier for people to survive. At this time, the United States was in a hurry and wanted to install a cannon, but it was stunned!

In the US military industry, which has a caliber of 20mm, is called a cannon. Since it is called a cannon, it must be used for the process and specifications of the cannon, and the tolerances are also the same. Therefore, the tolerances of domestic 20mm aerial cannons in the United States are the same as those of large-caliber field cannons. Of course, there is no problem with this error of 155mm long-legged Tom, but it is done on a 20mm aerial cannon. It is not easy to barely match it after making it. If you can't fire the light chamber, you can get a 1mm tolerance. It's really useless.

The Armament Commission of the Army Aviation discovered the problem and ordered it to correct it. Unfortunately, military capitalists were absolutely unwilling to give up this piece of fat. They argued with reason and were unwilling to change the process. The cost would increase a lot, and the price was locked. After improvement, every production would lose money. However, under the existing system, no matter whether you can actually use it, at least it is "qualified" in inspection, and can reasonably and legally manage the financial department to ask for war funds... The final result was that the United States was full of machine gun reserves (unqualified products) in the warehouse but could not be equipped, with a quantity of up to 50,000. Because it was not one factory doing this, but all factories did this. Otherwise, how could it win the bid with a low-priced "qualified" product in the arms tender issued by the Ministry of Defense?

If it is a dictatorial country like Germany, if problems are found today, Hoffman would gather people to meet to order rectification in the evening, and he would have to act the next day. If there is no effect, he would have to order people to be shot in two days. Now the head of state kills people, such as Hitler Liso, generals, Junker nobles, industrial tycoons, and disobediently cut them all. Besides, Hoffman knew that Hitler had suffered enough to be miserable. He didn't want to turn into a corpse in the bunker and could only force himself to kill. But democratic countries cannot do this. They must re-process and adjust the bidding price and issue new regulations, but this is also troublesome. What if there are members of parliamentarians who are idle and go through the old accounts of the 50,000 cannons and then hold them accountable? What if someone suggested that since it was a non-qualified product, he would order the funds to be recovered? Finally, with the efforts of the lobby group, the whole thing was simply left alone.

Finally, a smart person thought of a solution. Aviation guns were still in urgent need. If you can't make it domestically, just import British goods at domestic prices and some transportation costs and other costs to import British Sispanno cannons. So a funny thing happened. The United States paid for importing British aviation cannons that were already very nervous. They also flew back from strategic transport aircraft thousands of miles away. What's even more funny is that these cannons were still produced with American aid materials. In other words, the United Kingdom actually only manufactured OEMs, and the United States knew this OEM technology!

Then someone suggested that it was not a solution to always import machine guns from the UK, and asked domestic American manufacturers to imitate them. The result was even more funny. The problems that originally existed on Sispano had been improved by the UK. The m2 machine guns that were full of problems were transformed in a mess by American manufacturers, but the outcome was still unusable! By the end of 1942, the US Army Air Force had stored 4 million rounds of ammunition, but could not find a reliable machine gun.

This situation was almost over in 1943 and had not improved significantly. In the fighter instructions for tendering in 1944, whether it was equipped with fighter jets from Luhai Airlines or the 12.7mm Browning heavy machine gun that remained unchanged for thousands of years (historically, the problem of US military cannons was not solved until December 1945). Faced with this situation, the British really wanted to laugh but did not dare to laugh. On the one hand, they continued to "produce" the Sispano machine guns according to the requirements of the United States, while they were busy dismantling the machine guns on the p51bp47 aircraft that the Americans helped them to themselves and replaced them with Sispano machine guns. The Americans were confused, and the British pilots were not confused.

The sky gradually became brighter, and the P51s covered the few remaining transport planes and fled in a hurry. At dawn, the fierce battle allowed the Germans to harvest 60% of the transport planes. Hartmann alone accepted the results of three P51s and five C54 transport planes. In the end, he was really struggling to catch up with the ammunition...
