When leaving the headquarters, he met Chuikov, and the comrade commander of the city defense looked haggard, but he was in a good mood! Lin Jun originally had something to do with Cui Kefu tomorrow morning, and this would be just right!

Pulled Chuikov to the side, "If you're not in a hurry, come with me to take a look outside?" ”

Originally, Chuikov wanted to make a report to Zhukov on the follow-up issue of coordination between the city defense troops and the headquarters of the front army, because it was very cumbersome, otherwise the lieutenant general would only need to greet him on the phone, and he would not need to coordinate in person. Pen "Fun" Pavilion www.biquge.info but this will Lin Jun want him to go out for a stroll with him, of course he will go - the deputy commander will not be idle, nothing to pull him to hang out.

The debriefing is not very urgent and can be postponed.

"Vasily Ivanovich, do you have any ideas for where you will go in your personal work?"

Lin Jun did not rush to get the armored car waiting outside the command, but first took Chuikov to his office.

Chuikov chuckled in his heart, but immediately replied very firmly and affirmatively: "Obey the decision of the Central Committee, I am ready to go to any post that requires me." Marshal, if possible, I would like to be able to command an army group. ”

The troops are about to be reorganized, and as a highly decorated commander in Minsk, Chuikov is now facing a somewhat delicate situation! Obviously, it is impossible for a first-level commander of the front army to choose a commander with too few qualifications like Chuikov, and holding a deputy post or other position in the command of the front army command is not suitable for Chuikov's ability.

He is the material for serving as the chief officer.

The first sentence of Chuikov's meeting was to show his determination, and the second sentence was to tell the truth -- the power of the commander of the defense of the city of Minsk was greater than that of the commander of the army group some time ago, for example, Chuikov now commands two army groups in his hands, not counting other "miscellaneous troops".

Instead of holding a position such as deputy or chief of staff of the front army, it is better to command a group army to charge into battle!

Lin Jun smiled, very satisfied with Cui Kev's answer, and even more satisfied that he could tell the truth, "Just wait to be the commander of the Guards Group Army!" Based on the 62nd Army, the Central will soon give you a full-fledged army with powerful assault capabilities. This time the 62nd Army has become a banner in the Red Army, and after the reorganization, the strength will be very objective and will give you the best troops. ”

"Yes, Marshal!"

In the history of the Soviet Union, 11 armies of all arms and 6 tank armies were awarded the title of Guards, and after the Battle of Minsk, which was on a huge scale and unprecedentedly tragic, many armies were likely to receive the title of Guards, and even more military groups of other levels were awarded this honor.

The 62nd Army has been Minsk's "Dinghaishen Needle" for several months, and it would be unreasonable if it could not receive the title of Guards!

…….

Here, Lin Jun will not let the situation of "no reason" appear, and at the headquarters of the 1st Guards Division of the fighter plane, Kuori Dubu is wrapping his head and complaining: There is no reason! -- At noon today, just before receiving the news of the surrender of the German troops, he and his wingman were still patrolling the skies over Minsk when they encountered a German reconnaissance plane: Today, Kozhdub was really a little lucky, and he was actually hit in the wing by a 20-mm shell fired by the German reconnaissance plane in a panic!

In just one shot, although the reconnaissance plane was also killed by his own wingman, the wing of Kozhdub's landline plane actually came to a "blossom in the air"! The boat capsized in the gutter, the standard blossomed, and the wings fell apart! As a super ace who shot down 74 opponents, Kori Dub was lucky enough to successfully parachute from the unbalanced landline, but when he landed, he was hit by a small piece of shrapnel, and he didn't know if he was injured by mistake!

The reconnaissance plane was equipped with a 20 mm gun, which made Kozhdub a little annoyed, and even lamented that his luck today was a little bad! For a long time, as long as Lager's wing is not directly hit by the fuel tank, it can at least support it with a 20mm shell, and it will generally not be skinned to "bloom in the air" in an instant, and today is really unlucky for the captain!

Before Kozhdub had removed his parachute, Red Army soldiers came to his aid and immediately sent him to the rear to bandage his wounds, but fortunately the wounds were not serious. The Army brothers also sent a special car to take the Air Force hero back to the airport, and at night he appeared at the airport with his head covered.

"Is it that the German reconnaissance aircraft are equipped with new large-caliber aerial guns? But judging by the situation at that time, it was unlikely that it was a 30-mm shell. I'll be blown down as soon as I fire! Kozhdub is also a report of "intelligence".

On the premise of victory, Sergei did not ignore the reports of his subordinates, but the situation of Kozhdub was not among them: there were some things that he could not tell anyone.

"Commander Kobets sent me an internal notice the other day, so you don't have the right to read it. It's hard to know for sure that you can't find your plane and the wreckage of the German plane this time, but it's very likely to be a 20mm gun. Sergey handed over a document to his subordinates, "and forget about it after reading it." ”

Kozhdub looked at the report and seemed to understand something, "The Germans seem to be at a dead end again, but this time it's me who is unlucky, bad luck!" ”

Why did he say he was bad again? This has something to do with the problem of firepower of German aircraft -- the Soviet-made shells of the same caliber have basically been the most powerful in the world (at least the Red Army pilots think so), but this time the Germans seem to have made a small breakthrough with their own industrial base.

"Industrial technology is everything, and it's not necessarily wrong for the Germans." Sergei did not agree with Kozhdub's idea, and Comrade General thought deeper.

The reason for all this is that the shell that Kozhdub hit today is not ordinary, otherwise Rag's wooden wing would not have fallen apart so quickly:

Due to the technical limitations of the engine, the horsepower of the aircraft is very tight, and some countries are nervous to the weight of tens of kilograms, which will seriously affect the performance of the aircraft! The most typical example of this is Japan, but this phenomenon does not only exist in Japanese aircraft, but also in other countries.

For this reason, the Japanese have adopted an extreme deformed route of 'performance not protection', while the West has a much stronger foundation in the aviation industry than Japan, and the horsepower of the engine is higher than that of the Japanese, but many times it will still take the "golden mean" or find another shortcut.

Although improving engine horsepower is the fundamental way to improve aircraft performance, before the engine technology will not be broken through for a while, some necessary "technical means" have also been used by Western designers in their own aircraft: for example, Germany's Messersmit 109 uses a series of means such as narrow cockpit, single-beam wings, and small range to reduce the weight of the aircraft.

Among them, at present, the 109 has determined that the airborne weapons are two 20-mm cannons and two 7.92-mm machine guns, and reducing the reserve ammunition is also one of the means: according to the Red Army's intelligence and analysis of the captured wreckage, the 109F 20-mm aircraft gun has only 60 rounds of ammunition per unit, and the latter has 1,000 rounds of ammunition per unit -- the "golden mean" of maintaining high power and lasting combat effectiveness.

The 20mm cannon is the main combat power of the Bf109, and many other aircraft are also equipped, even on the reconnaissance plane encountered by Kozhdub this time! However, the 60 rounds of spare ammunition for each cannon on the fighter were obviously a bit insufficient (even if the two cannons were fired alternately, it was only enough for 7 seconds of continuous fire): in order to ensure the maximum results on the relatively weak ammunition level, the German technicians turned their minds to ammunition!

It's really technically excellent and easy to do!

According to the Germans' own experiments, high-explosive munitions and incendiary munitions are far more destructive to aircraft than single kinetic munitions, and high-explosive incendiary bombs that combine the advantages of the two can destroy the structure of the target by detonating and enhance the effect of destruction through combustion, which is the most effective means of dealing with air targets - regardless of whether the target type is a fighter or a bomber, their light metal/wooden structure is a fatal heel in front of high-explosive incendiary bombs!

The Soviet Union also understood this truth, but the Germans did it more extremely!

Therefore, German technicians came to the conclusion that the greater the charge in the warhead, the stronger the destructive ability against the target, on the premise of keeping the caliber and volume of the ammunition unchanged and the weight of the warhead not changing significantly.

As a matter of fact, the 20 mm cannon used by Germany is the Erikon MG-FF cannon imported from Switzerland, using a 20X80 mm shell with a projectile weight of 117 grams. Of the 117 grams of projectile weight, the real explosive weight is only 3.7 grams, that is to say, the explosive charge coefficient of this shell is only 3.2% (the loading factor is an important data to measure the power of the shell, that is, only 3.2% of the weight of the shell is used in explosives, and the power is relatively limited), and the remaining 113 grams are the weight of the projectile body and fuse.

Soviet artillery shells generally have a longer shell length than the German shell in the same caliber aerial guns, and the muzzle velocity is relatively larger, and the natural power is also greater! The German artillery shells had no advantage over other world aviation powers, and the situation was obviously not satisfactory to the Germans: the Germans created the 'M-Geschoss' shells.

The German translation of 'M-Geschoss' into English is 'M-projectile' - the improvement of the projectile structure is its focus.

The weight of the projectile of the 20X80 mm shell modified by the 'M-Geschoss' was reduced to 92 grams, but the charge was raised to a staggering 20 grams! It's almost enough to catch up with the 30-mm charge!

The reload factor has been increased by five and a half times compared to the previous one! The reload factor is an astonishing 22%.

Kozhdub was very unlucky this time, and suffered from this kind of shell - in fact, the Soviet Air Force had already encountered this kind of somewhat special shell, but it was not as "immediate" as Kozhdub: it was shot down by a reconnaissance plane, which made Kozhdub wonder why the power of German shells was so terrifying, and if it was a contest between fighters and fighters, who would have the leisure to study the power of the opponent's shells?

Some time ago, after studying the captured German guns and shells, the Aviation Committee issued that technical notice, but not to all pilots for morale reasons.

A reload factor of 22%, what kind of concept is this?!

You know, there was no 20mm cannon that reached this level during the entire Second World War! Even half of this level! For example, the same 20-mm cannon: the Japanese Type 99-1 aircraft gun has a warhead weighing 127 grams, a charge of 10 grams, and a reload factor of 7.8%; Japan's Ho-5 aircraft gun has a warhead weight of 79 grams, a charge of 7.7 grams, and a reload coefficient of 9.7%;

The Danish Madsen aircraft gun has a warhead weighing 126 grams, a charge of 6.5 grams, and a reload factor of 5.2%;

The Soviet ShVAK aircraft gun has a warhead weighing 91 grams, a charge of 4.7, and a reload factor of 5.2%; The Soviet VYa 23-mm aircraft gun has a warhead weighing 196 grams, a charge of 11 grams, and a reload factor of 5.6%;

The British Hispano aircraft gun has a warhead weight of 130 grams, a charge of 10.2 grams, and a reload factor of 8%;

Precision manufacturing, the craftsmanship of the Germans has indeed created a great achievement: the power of a German 20-mm artillery shell can even be said to be twice that of other countries' aircraft guns of the same caliber! To some extent, this alleviated the lack of firepower of the Luftwaffe due to the lack of artillery shells.

In the contest with the German fighters, the Red Army pilots often did not think about the threat of their opponents (either you die or I die), but this time Kozhdub was regarded as capsizing in the gutter, and he was obsessed with this "one shot".

In fact, the M-Geschoss shells were put into practical use by the Luftwaffe during the Polish/French campaigns and in the British air battles, proving the power of the M-Geschoss shells. Especially in the British air battle, it was proved that even a relatively strong aircraft such as the Spitfire would be destroyed or had to be out of battle if it was hit by a single 20mm 'M-Geschoss' shell in the main parts (such as the cockpit, engine, radiator, tail, etc.).

In the face of the power of the 'M-Geschoss', the flame-breathing bulletproof glass and cockpit armor could not protect its driver!

However, this is not the limit of the 'M-Geschoss' shells at the 20 mm level. The Germans soon went one step further: 'M-Geschoss-MX'. The new 20-mm shell was made from a further increase in the charge of the 'M-Geschoss', and the weight of the charge in the warhead reached an unprecedented 25 grams, with a reload factor of 24%!

As soon as the frame is scattered, Kuori Dub is actually not wronged!

But the Germans' precision manufacturing will continue, and it will not be just the 20 mm: the 'M-Geschoss' will continue to break new ground – and when the Luftwaffe loads the 30 mm guns on the aircraft, the 30 mm 'M-Geschoss' shells will also be introduced!

The first 30 mm 'M-Geschoss' shells were used on the MK108 gun, which used a 30X90RB shell with a warhead weighing 330 grams, a charge of 85 grams, and a reload factor of 26%!

More than 1/4 of the weight of a high-bore pressure gun shell is used on explosives, which is probably a world record! In contrast, the Japanese 30-mm guns of the same period had only a charge of 29 grams, and the reload coefficient was 11%; The American 37-mm gun had a charge of only 45 grams, and the reload factor was 7.4%; The Soviet 37-mm gun had a charge of 35 grams and a reload factor of 5.1%.

The charge of the German 30-mm artillery shell was more than double that of the Soviet Union's vaunted and powerful 37-mm aerial gun!

The more powerful MK101 and MK103 30mm guns will be fitted with the 'M-Geschoss' warhead applied to the 30X184R shell: 80 grams of explosives in the 330 gram warhead will still have a frightening 25% reload factor!

The 'M-Geschoss' type ammunition at the 30mm level will be a nightmare for Allied heavy bombers! Even a heavy bomber as strong as the B17 Flying Fortress can have fatal consequences if hit by a 30mm 'M-Geschoss' shell! If you hit three or five shots, it's basically over! The Me109, Fw190, and later the Me262, which used 30mm guns, were all bloody butchers of Allied heavy bombers!

In a historical air battle, 6 ME262s shot down 15 B-17 heavy bombers in just 6 minutes! You must know that the ammunition capacity of the M262's 30mm cannon is limited (a total of 4 MK108 guns, two with 80 rounds and two with 100 rounds.), and this achievement is naturally inseparable from the help of 'M-Geschoss'!

The pinnacle of the 'M-Geschoss', and the ultimate creation, was the 50mm 'M-Geschoss' shell used on the BK5 aircraft gun. The Germans loaded 350 grams of explosives into this 'large' shell with a 1,520-gram warhead, with a reload factor of ....... It doesn't matter anymore, what matters is: any man-made object flying in the sky is like paper in front of such a cannonball - if it hits, it will inevitably become flying ash!

Low muzzle velocity, short barrel, but why the MK108 is often said to be "not blown" - depending on its reload factor!

However, the 'M-Geschoss' was not the right way to develop the artillery shell, because the Germans greatly reduced the thickness of the projectile in order to fit more explosives into the warhead, and the side effect of this was that the weight and quantity of shrapnel produced by the projectile when it exploded were reduced.

Moreover, the unsuitable production of such high-power thin-shelled shells, and the obviously high level of processing requirements, constrained the development of the 'M-Geschoss' shells - the experts of the Soviet Aviation Committee had long dissected the German shells, but did not want to improve their ammunition according to the German ideas: this did not correspond to the status quo of Soviet industry, and only the Germans and Swiss, who were skilled in precision machining, could manufacture them on a large scale like that (it was an open secret that Switzerland became a German arms supplier in World War II, This was described in more detail earlier. ）。

However, the value of 'M-Geschoss' is still huge, and in the era when prefabricated fragmentation technology is not yet mature, it is extremely effective for aircraft guns to increase their power by increasing the charge, especially for countries like Germany that are under great pressure in air warfare.

It meant that German pilots could shoot down their opponents with fewer shells, in less time, and with more opportunities to shoot down their opponents in a single sortie.

The contest between "effective" and "precise" is also being fought on this small warhead. (To be continued, if you want to know what will happen next, please log in to the www.qidian.com, more chapters, support the author, support genuine reading!) (To be continued.) )
