B&Z tactics, simply put, is to seize the height, and then dive high to attack the enemy, if unsuccessful, continue to climb and regain the altitude, and then repeatedly repeat the process of diving attack and climbing to seize the height until the enemy is destroyed, the whole battle process is to pay attention to grabbing the height.

This tactic has very high requirements for the aircraft's high-altitude vertical energy and engine power, and for the lack of engine power, the "zero" type obviously can't fight with the FW190, the "zero" type relies on its own light and flexible characteristics and is good at low-altitude grappling, but it is not so powerful in the high-altitude and high-altitude state.

Of course, if the FW190 is stupid enough to descend at a low altitude and play dogfights in a nimble "Zero" style, it will be asking for trouble, even if the P51 is not much better than playing dogfights with Zero.

The United States was able to break the Zero, in large part because it captured a nearly intact Zero for them to study carefully. Otherwise, it is estimated that you will have to pay more losses to figure out this problem.

However, Tu Qianjun was not among them, so when he developed and guided the Air Force combat concept, he had already said the advantages of Tiger Shark I to the fullest! It's B&Z tactics! Swoop! Swoop! Swoop again!

And Tu Qianjun's positioning of the Tiger Shark I is an interceptor! As a result, the bombing function was completely simplified, and the range of the pit father was also excavated and strengthened.

As early as 1930, Tu Qianjun had already obtained the authorized production contract of the Wasp air-cooled engine of the American Pratt & Whitney Company through an agreement, and carried out related development work, and then under the auspices of Hou Xiaoqiang and others, the first engine developed by himself was the single-row cylinder "Hengshan 132 type".

Subsequently, Tu Qianjun joined forces with German construction machinery experts to develop air-cooled engines. The new Hengshan 139 uses two Hengshan 132 engines to assemble a double-row, 18-cylinder Hengshan 132 engine, and uses the prototype of the FW190 for test flights.

Of course, at Tu Qianjun's suggestion, this engine was equipped with a "Lu-style" supercharger, and the fuel tank was enlarged as much as possible, and a series of optimization improvements were made. This has a range of 1,600 km.

Although it has not reached the perverted level of 3350km after the "zero" type mounting auxiliary fuel tank, it is basically enough. As for bombers or something, Tu Qianjun doesn't think about it yet.

It is enough to produce fighters, as for bombers and large bombers, let the Americans get it! At most, it would be nice to provide your own blueprints, such as the B-26!

"Is there any arrangement for the Führer on the way?!" Tu Qianjun frowned and said in a deep voice to Rom. To be honest, he didn't appreciate this kind of exploitation of a little girl.

Federica is full of calculations. I'm only 19 years old now. A 19-year-old girl flying a plane from Berlin to Manchuria is extremely risky!

"Actually, there is no need for the Führer to arrange it, His Royal Highness Federica's brother His Royal Highness August has already arranged it......" Rohm said with a wry smile: "In fact, without the approval of His Royal Highness Auguste, His Excellency the Führer would not want to just meddle in like this......"

Tu Qianjun couldn't help but be stunned when he heard Rom's words, and then understood why the ambassador was full of bitterness. I'm afraid of the mustache's sentence: Hugging the beauty is actually the most helpless blessing, right?!

"Where is Federica now?!" After a pause, Tu Qianjun said in a deep voice to Rom. You know, even if it's a straight-line distance. Berlin is more than 7,500 kilometers away from Mukden!

"It's already in India." Rom couldn't help but smile bitterly, this Royal Highness Princess Federica is too bold! Even if Rohm was asked to come by himself, he wouldn't dare to fly to Asia just like that!

Not to mention the chaos and chaos along the way, even the slightest problem in the air of the plane may be destroyed and killed! Why is she so bold?!

"Her Royal Highness Federica has been on the road for more than a week and has not been found before. It wasn't noticed until these days. ”

As he spoke, Rohm smiled bitterly and said to Tu Qianjun: "His Royal Highness the Prince of Hanover has exerted a lot of pressure on us, and the Junkers seem to be very dissatisfied with this matter......"

Listening to Rohm's words, Tu Qianjun knew that this matter was already a big trouble! The old-fashioned European aristocracy, especially the stubborn aristocracy of the Junker type, valued honor and bloodline beyond imagination!

The House of Hanover is a proud family that has been born out of the King of England. It is even more impossible to marry his daughter to a local warlord like Tu Qianjun at will.

Federica must have known what was going on, so she chose to run away from home on her own. You don't have to think about it to know that this is in the eyes of the Hannover family, who value reputation. What a rebellion!

But the attitude of the mustache also says something, and the mustache seems to want to attack Juncker's authority. It seems that the Junkers really suppressed the mustache enough!

"I know how to do it...... Tu Qianjun was silent for a while, and said to Rom: "Contact Federica and ask her to drive the plane to Kunming, Yunnan, and I will plan a flight route for her to Shenyang!" ”

At this moment, Tu Qianjun already had a plan in his heart, of course! This can't offend the Junkers as the mustache wants. As for Federica, Tu Qianjun hadn't figured out what to do.

Come on, come on! The corners of Tu Qianjun's mouth curled up with a warm smile, a 19-year-old girl is willing to take risks all the way to find herself, if she says that she is not moved, it is a lie.

Or it can be said that Tu Qianjun didn't expect Federica to make such a choice!

At this time. Rohm also saw that Tu Qianjun had no interest in talking. He said goodbye and left the office in a playful manner, looking at Rom's back, Tu Qianjun suddenly felt that the head of the stormtrooper who was killed by the mustache in history was a little pathetic.

In fact, the mustache was wondering what to do with Rohm, who had done something for the Nazi regime, but he could not remain in prison or exile, so that society at the time would pay unnecessary attention to this reckoning.

In the end, the mustache chose "bright rise and dark fall". Rohm was appointed Deputy Minister for Foreign Affairs and German Special Envoy to the three eastern provinces. This was already the best result, and Röhm's subordinates in Germany were largely cleansed. He is no longer influential.

And leaving Rohm's life is just that the mustache feels that Rom is far away in the three eastern provinces and is no longer a threat. Thinking of the friendship of many years, this did not put him to death.

Rohm also knows his situation, he has despaired of politics. Honestly his envoy. It's semi-retired.

"Chandinand!" Tu Qianjun roared angrily outside the door, and then Shang Dinan rushed in!

"Generate electricity for Long Yun, a good friend of mine is about to borrow their airport in Kunming. Let them get ready to welcome them, and make it grand! Let's just say that the princess of the royal family of Hanover, Germany, is doing a trip around Eurasia! ”

A smile tugged at the corner of Tu Qianjun's mouth, and he said to Shang Dinan: "Also, inform Aban and Snow." Let them go for an interview, I'm sure a princess of the Hannover royal family will be interested in traveling around Eurasia! ”

Aban and Snow were largely based in Manchuria, where they could have an inexhaustible variety of subjects. From economic construction, to war collection. Of course, they occasionally leave the three eastern provinces to go to other places to collect wind.

But basically, it is the three eastern provinces that are stationed. The ambitions of the Japanese for Shanghai were already evident in the last Battle of Songhu. For the safety of their own business, most businesses have moved their business to a safer Dalian.

At least, it was under the jurisdiction of the Wehrmacht, which had defeated the Japanese in the past. No matter how bad it is, it's better than the war that may be brought by the war in Shanghai at any time, right?!

"Hmm...... Let the "Fengtian Daily" publish an article saying that the princess of the royal family of Hanover, Germany, is doing a flight around Eurasia, and her destination is Mukden! The momentum is going to be bigger! ”

"Yes!!" Chandinand replied loudly, and then hurried down to deliver the order.

Tu Qianjun used propaganda to create momentum first, and Snow belonged to the Chicago Tribune reporter. Aban is a reporter for The New York Times. If they know, then the European and American worlds will also know!

At that time, the Hannover royal family can be regarded as having a step down, and it is easy to talk about it without losing face. And if Federica had completed this flight, there would have been no doubt that she would go down in history. The faces of the Hanover royal family also shine.

The bad reputation of running away from home and going down in history as the first woman to fly across Europe and Asia are two choices that the Hannover family will make the right choice. As for the future...... Let's talk about it later!

The corners of Tu Qianjun's mouth curled, could it be that Hanover could still cross the Eurasian continent and kill the three eastern provinces to find trouble? !

At this time, Federica's snow-white little face in India looked a little tired. In order to come, she rarely rested along the way. I'm also scared when flying an airplane.

Fortunately, her brother August took care of everything for her on the road, which made her not so hard.

"I promised you that if you still insist on going to him after the year then I will help you." That's what her brother Auguste said to Federica before she left.

"As the eldest son of the family, I can't make such an independent choice as you. But I still want my sister to be happy! Auguste touched Federica's hair and whispered, "I know you love him, but I can't be sure if he loves you." All I can do is give you a chance to do what you want. ”

"I hope you can live happier than I am." Auguste's eyes were full of pity, and he whispered to his sister, "Take my share." ”

Federica held her head, still thinking about what her brother had said to her before leaving. The excitement of leaving has disappeared. Now there is a slight fear in her heart!

I've already arrived in India, what if I can't go to China?! Within China, Germany's influence is limited! Even if I go to Mukden, what if he doesn't see me?! For a moment, Federica's heart was in turmoil. (To be continued)
