PS: This chapter is 4000 words, slightly making up for the old accounts, thank you for your support......

Hartmann then aimed at the next one, but he himself was stunned after firing, not because he easily broke through the 100 mark, but because he only fired a few shots, and the P51 on the opposite side actually exploded into a ball of fire and fell from the sky. Pen %fun %Pavilion www.biquge.info he was dumbfounded when he saw this scene? If you think about it, you suddenly connected to what the aeronautical engineer said when he introduced the performance of the aircraft last night: the Do-412 is equipped with the latest air combat artifact, the MG-213, and you will definitely know how powerful it is.

Hartmann only knew that the MG213 and MG151 were both 20mm cannons, and his intuition was that the former was a rotating rifle gun, so the firing speed was faster and more powerful, but he ignored the difference in ammunition - although both used 20mm diameter ammunition, the former used 20mm × 146mm ammunition, and the latter was 20mm ×82mm. Because of this, the original Do-412 was to install a 4-door MG-213, but because of the limited engine power, it could not carry such a heavy armament, and finally became a combination of 2-door MG213 + 2-door MG151, even then there were engineers who were too heavy and wanted to adjust it to a combination of 4-door MG151, but Mr. Dornier refused to agree.

Not only did Dornier refuse to agree, but even Dr. Tan Ke copied this configuration, and the Fw-190A8\A9 series that left the factory behind were all a combination of 2-door MG213 + 2-door MG151, and was there an aircraft with a full 4-door MG213? The answer is naturally yes, one is the Me-262 with greatly increased thrust after replacing the engine, and the other is the 8 Ta-152s that the Air Force brought for verification this time.

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 Jumo213 liquid-cooled engine this time, but directly used 2300 horsepower, DB603 liquid-cooled engine with two three-speed superchargers and L-shaped intercooler, the maximum speed can easily reach 727 km / h, if combined with MW50 + GM1 two drug systems, the speed can be increased to 760 km / h, The practical ceiling is 14,000 meters. The fastest speed, the most fierce firepower, and the highest altitude made it the pet of the Air Force boss from the moment it was born, and in the words of Kesselring, Jeshunek and others, it was "perfect!" ”

Of course, the phrase perfect Tan Ke himself did not dare to say, because he ran into an opponent. Ta-152 originally had two versions, one is Ta-152C, the other is Ta-152H, the former focuses on medium and low altitudes below 7000 meters, and the latter focuses on medium and high altitudes above 7000 meters, especially above 9000 meters, the most significant difference between the two is that the wingspan of the H type is more than 2 meters longer than that of the C type, so the high-altitude utility is better. And his old friend Dornier was also unwilling to accept that the Do-412 could only be used at medium and low altitudes, and also secretly developed the Do-412H model, trying to get a piece of the pie in the field of high-altitude volleys.

The planes of the two sides often get together to compete and study. It was found that at medium and low altitudes, especially at medium and low altitudes below 6000 meters, although the absolute speed of the Ta-152 was faster than that of the Do-412 (of course, faster than P51\P47, etc.), the maneuverability and flexibility were inferior to the Do-412, and in the high-altitude field, the Do-412H model, which had been painstakingly developed, was not an opponent - the liquid-cooled engine had a natural advantage at high altitude, and this was already taking into account the fact that the Do-412 did not get a 2300 hp air-cooled engine. If you just look at the current 2000 horsepower 801 engine, the difference between them is even greater. In the end, the two sides agreed that below 7000 meters, the Do-412 could perfectly replace the Fw-190 and Bf-219, and above 7000 meters, and the Ta-152 could perfectly replace the Fw-190 and Bf-109G\K (this is the last improved series of the 109 series by Messerschmidt, focusing on high-altitude volleys).

This unanimous view unabashedly exaggerates the ambition of both men - to completely drive the Messerschmitt company out of the fighter market! The Do-412 and Ta-152 teamed up to have nothing to do with Messerschmidt's propeller space, and the success of the single-engine Ta-183 test flight means that the jet world is set to change dramatically in the coming year. After hearing the news, Dr. Messerschmidt was angry and anxious, on the one hand, the company's main Bf-319 (Gale Moddies) is not yet in the climate, on the other hand, the inherent weakness of the Me-262's twin engines can no longer be adjusted, so he can only hope for a new generation, and he is seriously ill, but Jiro Horikoshi, who is in charge of the 319 project, advises him not to worry, everything is still undecided......

Pilots don't care about the grievances and grievances behind these big companies, right and wrong, they just want to fight well with the planes, at the moment when Hartmann fired, the rest of the combat planes were also firing violently and continuously, and the attack targets were P51 and transport planes, although the number of escort P51 was twice that of the German fighters, but the numerical advantage was not equal to the tactical advantage, especially the Fw-190A8 drawn from this time were the most experienced veterans in dealing with 4-round bombers on the Azores, The original intention of Marchar to transfer them was to deal with the endless stream of US heavy bombers, because it was always powerless to fight with the Bf-219, but he didn't expect to encounter a transport plane that was weaker than the bomber, which was basically equivalent to a tiger entering a flock of sheep and reaping it wantonly.

I saw an Fw-190 pounce on the C-54 Airlord at close range, although the US machine gunners opened fire fiercely, but the German pilots turned a blind eye, fiercely aimed at the opponent's wing part and continued to strafe, the 20mm thin-shell bullet was beaten like a storm, and in less than 5 seconds, the wing of the plane was broken from the root of the wing, and the outcome can be imagined - take the plane and bring people to fall down together! Others aimed at the transporter's massive vertical tail and fired. These are all veterans who are used to fighting birds, knowing that the US military aircraft has thick skin and rough flesh, and they can't help them by opening a few holes in the general position, but the wing root and vertical tail are fatal points, as long as they hit, there is no reason to survive, and the MG213 factory has exacerbated this panic, as long as it hits 8-9 rounds, a 4-round bomber or transport plane will be finished.

Of course, MG213 is not the most powerful weapon against transport aircraft, the most frustrating is the R4M rocket carried by Fw-190, the brilliant brilliance of the 24 salvo flying in the sky makes people's scalp numb, all the paratroopers who have landed and are landing in the air do not dare to raise their eyes to see, this kind of rocket can blow up the huge transport plane as long as one shot, if there is a paratrooper unfortunately in the explosion range, keep it as a black charcoal! In just 2 minutes, 4 transport planes that were desperately fleeing were easily caught up by German fighters, and then smashed down into fireballs. Fortunately, the Germans still have a gentlemanly demeanor, and all US officers and soldiers who parachute will not be killed, regardless of whether they are crew members or paratroopers, because the pilots know that they will inevitably have the day when they parachute, and if they kill their parachute opponents today, they may be covered with machine gun holes when they parachute tomorrow. This tacit understanding also extends to the fact that when attacking a ship, it is of course natural to strafe the ship, but after the sinking of the ship, there is no need for the officers and men who have lost their ability to resist to kill them all.

When the Germans attacked with an endless stream of powerful weapons, their opponents, the P-51B fighter pilots of the US Army Airlines, could only live with 4 or 6 12.7mm machine guns, and what was even more tragic was that due to the design of the bullet chain supply angle, the bullets were often jammed (the P51 was designing the D-type, and the top priority was to solve this jamming problem), of course, this was not because the American ordnance designers did not know how to install cannons on aircraft, nor did the United States have no cannons -- the United States had AN/N2 cannons. The British also had the famous Sispano.

The fact that most US planes do not have cannons is actually a problem of the comprehensive system. On the one hand, in the early stage, the US fighters mainly competed with the Zero in the Pacific theater, and in view of Japan's crispy characteristics, the 12.7mm machine gun was more than enough to deal with it, and the results were quite good, so 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, and if they were to install machine guns, they were afraid that if they nervously held down the firing button, they would be able to pour out all the ammunition in less than half a minute.

This set of theories began to fail after 1943, firstly, because the US military encountered more and more German aircraft, not to mention those attack aircraft and bombers, even the Bf-219 developed on the basis of Zero War The defense is much stronger than that of Zero War, not to mention the Fw-190, a thick meat machine; Second, the Japanese Navy is also gradually changing its equipment, a large number of Bf-109\219, Fw-190 began to be introduced, Japanese pilots are not stupid, of course they know which aircraft is easier for people to survive. At this time, the American side was in a hurry and wanted to install a cannon, but it turned out to be dumbfounded!

In the U.S. military industry, all guns with a caliber of 20mm are called guns, and since they are called guns, they must follow the process and specifications of the guns, and the tolerances are also. Therefore, the tolerance of the 20mm aviation cannon produced in the United States is the same as that of the large-caliber field gun, and this kind of error is of course no problem on the 155mm long-legged Tom, but it is finished on the 20mm aviation cannon, and it is not easy to barely put it together after it is made, and it cannot be fired at all -- the chamber alone can be 1mm tolerance, and it is really useless.

The Army Aviation Armaments Committee discovered the problem and ordered it to be corrected, but the military wage owners were absolutely unwilling to give up this piece of fat, and they were unwilling to change the process on the basis of reason - then the cost would increase a lot, and the price would be locked, and every time it was produced, it would lose money after improvement. Under the current system, regardless of whether you can actually use it or not, at least it is "qualified" in terms of testing, and it can reasonably and legally manage the war funds required by the financial departments...... The final result is that the United States has a stockpile of machine guns (substandard products) in its warehouses but cannot equip them, and the number is as high as 50,000 - because it is not one factory that does this, but all factories that do this, otherwise how can it win the bid with low-cost "qualified" products in the weapons tender issued by the Ministry of Defense?

If a dictatorship like Germany discovers a problem today, Hoffmann will gather people at night for a meeting to order rectification, and the next day he will have to take action, and if it is not effective, he will order people to be shot in two days -- now the Führer can kill people more than Hitler, and any generals, marshals, Junker aristocrats, and industrial tycoons will be cut down if they are disobedient, but Hoffmann knows that Hitler has had enough of the people under him, and he does not want to become a corpse in the bunker, so he can only force himself to kill. But democracies can't do this, they have to go through the process again to adjust the bidding price and issue new specifications, but this is also a big problem, what if a congressman is too idle to go through the old accounts of the previous 50,000 cannons and then hold them accountable? What if someone asks that the funds should be recovered because they are non-conforming products? In the end, thanks to the efforts of the lobby group, the whole thing simply came to an end.

In the end, some clever people came up with a solution, but the aviation cannons were still urgently needed, and if it was not possible to make them in China, they would simply import British goods -- import British Sispano's cannons at domestic prices, plus some transportation costs and other costs. So the funny thing appeared, the United States paid for the import of the British aviation cannons, which were already very nervous, and also flew back by strategic transport planes, and what is even more funny is that these cannons are still produced with American aid, in other words, the British side is actually only OEM, and the United States is completely good at this OEM process!

Then some people suggested that it was not a solution to always import cannons from Britain, and asked the American domestic manufacturers to copy them, and the result was even funnier, because the problems that existed on the Sispano had been improved by the British, and the American manufacturers had a messy transformation of the M2 cannon, and the end result was still one -- it could not be used at all! By the end of 1942, the U.S. Army Air Corps had stockpiled 4 million rounds of ammunition, but could not find a reliable cannon.

This situation was not significantly improved until 1943, and even in the 1944 tender for fighter jets, both the army and navy fighters were armed with 12.7mm Browning heavy machine guns, which had remained unchanged for thousands of years (the problem of American machine guns 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 "OEM" the Sispanol cannons in an unhurried manner according to the requirements of the United States, and on the other hand, they were busy dismantling the machine guns on the P51B\P47 planes that the Americans had provided to them and replacing them with the Sispano cannons -- the Americans were confused, but the British pilots were not confused.

As the sky gradually brightened, the P51s fled in a hurry to cover the few remaining transport planes, and at dawn the fierce battle allowed the Germans to harvest 60% of the transport planes, and Hartmann alone laughed at the results of the three P51 and five C54 transport planes, and finally ran out of ammunition to catch up......
