Xu Jun walked into the slightly cramped command room under the guidance of Zaft, and most of the accompanying personnel could only stand outside the door and wait. The captain of the radar squad on duty and his six subordinates saluted the Führer with excitement, and then began to introduce the equipment in the command room under Xu Jun's questioning.

The original chief and auxiliary rooms were not spacious, and the navy cut the officers' quarters on both sides to expand half of the space, and now the entire rear of the command bridge has been constructed as a whole, and the navy has tried its best to stuff a full set of radar observation equipment into this limited space, and has specially laid cable pipelines and communication pipes.

The outer armor of this room was originally only 20 mm, and due to the change in function, it was clear that this thickness could no longer meet the current needs, for which the Navy specially added an additional layer of 30 mm armor to the outer layer.

The Navy's plan is to build a comprehensive intelligence room at the bottom of the bridge, where all electronic intelligence and optical observation information will be aggregated, and after integration, the target parameters will be transmitted to various command posts and fire control departments, so that the erroneous data reported by some observation points can be effectively eliminated and the fire control and command confusion can be avoided.

Xu Jun personally operated the radar device with great interest, of course, in simulated training mode, he was very satisfied with the newly designed PPI display, he had seen similar products in books and museums, this kind of display is a real force multiplier, in Xu Jun's opinion, its impact on the war can even be compared with the radio proximity fuse.

Although the accuracy of the Bismarck's sea search radar is not yet able to meet the needs of fire control, this is already a technological leap, and Xu Jun believes that the Navy's electronics department will be able to develop more sophisticated follow-up products on this basis, and the design of the precision fire control radar has been mentioned above the top priority development project.

It's just that the development of the Navy takes time and resources, and in reality it is impossible to achieve it overnight. Xu Jun can only help the navy improve its combat capability as much as possible within the overall development framework. At present, the focus of Germany's development is still on the army and air force, and there is no way to tilt resources towards the navy in the short term. However, the Navy has now received far more money than the budget in its original history combined, and now it has a deep face, waving gold marks everywhere to purchase equipment.

The transformation of the domestic military industry is gradually underway, and many departments have been exposed to the situation that the output cannot meet the needs of the expansion of various troops, and Xu Jun feels that this is just the expansion of military production. An opportunity to carry out the general mobilization of industry and commerce throughout the country, making full use of the capitalists' instinct for profit, completely awakening the German war machine, and going all out to devote himself to Xu Jun's army expansion plan.

Xu Jun cordially shook hands with the officers and men of the radar squad one by one, and expressed encouragement and expectations to them. Xu Jun also gave everyone present a photo of him autographed, and the officers and men of the radar squad could not restrain their excitement and stomped on the deck to swear allegiance to the great Führer.

Walking out of the radar room, Xu Jun said that the visit to the bridge was enough, and he wanted to go down to the deck for a walk. By the way, take a look at the renovation project of the armed side that he is most concerned about. Colonel Zaft hurriedly led the way in front, and following the escalator inside the bridge, the group returned to the main deck.

"My Führer, the SKC34 is indeed already a little behind in terms of performance, and in accordance with your orders, we have instructed Krupp to develop a new replacement." Raeder stood by the turret of the 150mm secondary gun with his hands behind his back and introduced it to Xu Jun.

"The dual-purpose of secondary artillery will be the mainstream of the development of the world's navy in the future, and the achievements of the Luftwaffe have proved how great the threat of aircraft to sea targets is, and the German Navy will inevitably face threats from the air in the future. Before the start of the war, the Navy was not prepared for this accordingly.

You also saw with your own eyes the results of the last exercise, facing the assault of BF110 and BF109. The anti-aircraft firepower of the German surface ships was a fictitious disposition, with Admiral Schell holding out for forty seconds and Scharnhorst for only two minutes, and finally being dropped with a deck of dyed shells. After Xu Jun finished speaking, he turned around and walked along the deck towards the stern, and Raeder and his attachés hurriedly followed.

"Good, that's the normal configuration. The kind of chaos that preceded it was nothing short of dereliction of duty. Xu Jun pointed to the SCK37 105mm anti-aircraft gun set up on the air defense deck next to the bridge at the rear and said.

"Rheinsteel has disposed of those responsible, my Führer, and the Navy has also stripped those responsible of their military status, and they have been handed over to a military tribunal, in accordance with your wishes. They will pay for their malfeasance. Raeder walked up to Xu Jun and replied respectfully.

"I can't imagine what kind of chaos this will cause on the battlefield, you should understand what kind of consequences this will cause in the fierce air defense battle, their behavior is tantamount to murdering our soldiers, it is absolutely unforgivable, and must be severely punished." Xu Jun said to Raeder with a serious expression, and the Admiral quickly nodded in agreement.

In fact, this kind of thing is very common in the German Navy, because the German Navy's construction plan is relatively chaotic, and it is often necessary to serve politics, or for a commemorative day, or for the request of a big person, the shipbuilding department often needs to rush to work, even at the expense of launching early and then towing back to the slipway.

However, this incident on Bismarck can indeed be regarded as dereliction of duty, because of the order of installation, the same anti-aircraft gun was divided into two models. In fact, this is not a big problem, the problem is that the latter's fire control system is not compatible with the original installation, which is tantamount to artificially dispersing the anti-aircraft fire of the battleship, and the anti-aircraft guns on the same side are divided into two groups in front and rear. Bismarck eventually collapsed, and there was no reason for this.

"The SCK37 is a reliable anti-aircraft gun, and my Führer, Rheinsteel, has designed a new model based on it, and we have installed a new silo near the gun emplacement, and the chain loader can supply the ammunition needs of four turrets at the same time." Colonel Zaft reported from the sidelines.

"This small bomb lifter has long been used on the Berlin anti-aircraft batteries, and this is only an experimental modification. When the design of the new high-level dual-purpose turret is completed, these anti-aircraft guns will all have to be replaced. Xu Jun walked to the gangway of the rear air defense deck and began to climb towards the anti-aircraft artillery platform.

The configuration of the German Navy's anti-aircraft firepower has always been a confusing question, and many people cannot figure out why the German Navy would take its own anti-aircraft fire so lightly. In fact, if you look at it in conjunction with Germany's naval strategy, everything has a reasonable answer.

The German Navy was developing an assault fleet, and its goal was not to fight head-on with its opponents. Rather, they are ready to fight guerrilla warfare in the oceans.

Like the mainstream thinking of other navies around the world at the time, the German Navy did not believe in the capabilities of aircraft carriers, and even if they built Zeppelin, their purpose was only to escort and reconnoitre, not to attack enemy warships. The firepower of the Zeppelin aircraft carrier is obvious evidence, this aircraft carrier has the firepower of a heavy cruiser, and is obviously ready to engage in a single ship raid under the encirclement and suppression of the British army.

Bismarck was along the same lines, and the German Navy did not think that she would be much of a threat from aircraft. On the European coast, she would be closely protected by the Luftwaffe and would not have to worry about being hit from the air at all. Her battlefield will be deep in the ocean, far beyond the range of the enemy's land-based air force, not to mention how easy it is to find a lone warship in the vast sea, even if occasionally discovered by the adversary, Bismarck can quickly disengage with the high speed with its nimble maneuverability.

In fact, in the original history, the Bismarck did take this tactic to the extreme, and disappeared from the sight of the British army several times, if not for the eventual torpedo damage to the rudder. The Bismarck had already jumped out of the British encirclement and returned to the umbrella of the German land-based air force.

Xu Jun did not want history to repeat itself, even though the British Navy was almost completely wiped out. But the future opponent has a strong air force, relying on Bismarck's original anti-aircraft firepower, it is difficult to believe that it can be retreated.

For this reason, Xu Jun used the Bismarck as an experimental platform, trying to find the best configuration scheme possible. At present, this is the most basic renovation, and there will be updated plans in the future. The Tirbitz was the ultimate beneficiary, and the ship was now absorbing the Bismarck's experience in the rebuild. At the same time, the final equipment integration was being carried out, and Xu Jun was looking forward to seeing the performance of the lone wolf in the north in the current time and space.

"My Führer, this is the twin-mounted Bofors anti-aircraft gun that you asked to be replaced, the performance is very reliable, and it can be commanded by the anti-aircraft artillery command post. You can also rely on the built-in sighting equipment to fight independently, and we use the bullet box to feed the ammunition, and the rate of fire and the duration of fire have been well improved. Colonel Zaft held the barrel of the Bofors 40mm cannon and introduced it to Xu Jun seriously.

"Are the soldiers accustomed to using this weapon, and how do the soldiers feel compared to the previous SCK30 37-mm anti-aircraft guns." Xu Jun asked curiously.

This really intrigued him, and what kind of mentality the German naval soldiers had in mind to operate the original 37-millimeter anti-aircraft gun to attack the enemy planes approaching at high speed.

The SCK30 has been widely circulated as a joke of the German Navy in later generations, and later generations called it the Sanqi Hand Pull Machine because of the strange single-shot fire mode of the anti-aircraft gun. In fact, there are very reasonable reasons for its existence, the German Navy did not choose it to deal with aircraft, anti-aircraft air defense was only its sideline, and its main task was to protect against enemy torpedo boats.

In the eyes of the German Navy, the enemy's torpedo boats are more threatening than aircraft, and it is difficult to keep up with such high-speed surface targets by relying on the rotation speed of secondary guns, especially when the opponent breaks through to close range, the German army must have a small-caliber artillery with appropriate power to undertake the task of surface defense at close range.

The 37-mm anti-aircraft gun was capable of the job in terms of range and power, and could also take on part of the air defense tasks by the way, and the German Navy did not hesitate to choose it as a short-range defensive weapon. This is the reason why the perimeter of the 37-mm anti-aircraft gun emplacement is completely exposed to the emplacement, because it needs to have enough firing angles to fire at targets on the sea surface.

The idea of the German Navy has always been to fight in single or double formations, while in the navies of other countries, tasks such as anti-torpedo boats are entrusted to escort destroyers and frigates.

Now that the situation had changed, and the German naval strategy had been revised, Xu Jun had to correct the obvious mistakes, starting with strengthening the anti-aircraft fire of the naval ships, throwing away the hand-pulled planes, replacing them with Bofors' 40-millimeter water pipes, and dropping bullets at enemy planes.

"Very good, my Führer, the soldiers are very fond of these forty-millimeter anti-aircraft guns. In addition, the newly installed 20mm anti-aircraft gun is also very useful, and the soldiers like the scene of this machine gun firing very much, and there will be many onlookers every time, and the ferocious firepower is impressive. Zaft said, pointing to the machine gun nest on the upper platform.

There was originally a 20mm single-barreled gun, the same model used on most armoured vehicles, which was fed by magazines and had a rate of fire that was only slightly better than that of a 37mm anti-aircraft gun.

And now a brand-new anti-aircraft gun is installed there, and unlike the equipment on other gun emplacements, the half-covered armor shield of this anti-aircraft gun is painted with yellow letter numbers, which shows that it is still an experimental equipment and has not yet entered the stage of finalization and mass production. The finely structured cannon was surrounded by a chain belt, six pitch-black barrels arranged around the axis, and the silver-gray muzzle clamp reflected the icy cold light in the sun.

"MK206, I also like the way it fires. So I named it "Fafnier". Looking at the murderous six-barreled rapid-fire cannon, Xu Jun showed a happy smile. (To be continued......)
