Donald transferred a piece of glass in his warehouse by spies, but donald didn''t care too much. If he could find it back, it would be best. If he couldn''t find it back, he didn''t care. He was not afraid of the enemies of his country. He copied it after he got this glass.

    Because he knows that this is absolutely impossible. After all, even his base, if viewed according to the level of science and technology, has exceeded his current world for at least 50 years, but even so, he can do nothing about this glass, let alone the enemies of their country.

    Seven days passed quickly, and Donald''s aerial aircraft weighing more than 300 tons was finally assembled.

    Looking at the huge bomber named Phoenix by Donald, Donald and Hessen were suddenly proud. It took them nearly five years to complete the research, development and production of this 700 ton bomber day and night.

    Not to mention the energy money spent in the science and technology mall, only the human and material resources spent by their country in reality can not be calculated. Even now, they, the world''s top industrial power, are unable to manufacture a second such aircraft.

    The one ton of glass he bought from Wang Bin before, plus the five tons of glass he brought back this time, have been used on the aircraft. Besides being used in the cockpit, many key parts, such as the engine compartment of the aircraft, have been added with this kind of glass.

    After all, the fuselage and other parts of the aircraft are basically made of titanium alloy steel, so their strength and defense are very good. However, the thickness of titanium alloy skin is too thin, and its performance is far inferior to this special glass, so it is not invincible. Some air defense guns with a slightly larger diameter are still able to break through these titanium alloy skin.

    However, the glass he purchased from Tiangong technology in the technology mall is different. First, the impact resistance and other properties of these glasses are better than those of titanium alloy.

    At the same time, in terms of thickness, the thickness of these glasses has also reached more than 5mm. Even in the weakest wing, the thickness of the installed glass has reached 4mm.

    In this era, glass of this thickness can withstand the direct hit of air defense machine guns of more than one kilometer and about 14 mm, not to mention that it is impossible for such a huge bomber to reduce its height to less than 1000 meters during combat.

    As for large caliber anti-aircraft guns, which can reach more than 10000 meters and more than 100 caliber anti-aircraft guns, the main way to kill aircraft is also to cause damage by shrapnel, steel balls and incendiary agents. With the defensive power and incombustible performance of these glasses, it is almost impossible for anti-aircraft guns to shoot down such an aircraft.

    In other words, in his time, it was almost impossible to shoot down such a fighter.

    What''s more, the current state of the aircraft is only the most elementary. In the future, they will continue to transform the aircraft to make its performance stronger.

    For example, more than half of the 50 tons of special glass previously ordered from Wang Bin are actually prepared for the future upgrading of the bomber.

    Looking at the huge body of the bomber, Donald''s mind not only emerged the data of the fighter.

    Project code: Fire Phoenix.

    Model Code: Phoenix.

    Captain: 98m

    Wingspan: 116m

    Machine height: 20.1m

    Maximum flight altitude: 25000m

    Maximum flight speed: Mach 2.1

    Empty weight of fuselage: 330 tons

    Maximum takeoff weight: 705 tons

    Maximum range: 20000 km

    Maximum load capacity: 150 tons

    At the same time, Donald''s heart seems to have put down some heavy burden. He knows that with this fighter and the imperial examination level mastered by their country, as long as there are no accidents, their country has been invincible in this war.

    In other words, this bomber is definitely a real Zhenguo artifact for their country.

    You know, Donald is no better than the rest of the world! Because he has the ability to enter the science and technology mall to buy various goods in the science and technology mall, he naturally learned from other people in the science and technology mall about the outcome of the World War of other parallel worlds.

    If it goes on under normal circumstances, their country will not defeat their opponents after spending countless human and material resources, but it will eventually pull their opponents down to the status of world hegemony.

    Of course, there are also winners in this war, that is, the country on the other side of the ocean.

    But anyway, their country finally lost the war. For the losers, Donald certainly knows what to face.

    Therefore, for this time and space, their country will not repeat the mistakes. Instead of forming an alliance with noodle countries and Oriental island countries, they formed an alliance with the ancient oriental countries ten years ago, and madly improved their strength, so that they quickly got rid of the semi colonial state and completed the reunification at the same time. (I won''t write more here!)

    Now it can be said that it is the existence of this ally that gives their country a new strategy and gives them the confidence to fight against the world overlord.

    Although they can''t guarantee that their country has the ability to defeat their enemies, with the existence of this plane, they absolutely have the confidence to keep themselves from failure.

    With the complete assembly of the aircraft, the time for its test flight will begin soon.

    However, Donald is very relieved about the test flight of the aircraft, because the design of the aircraft is not designed in this era of the world, and has been tested in wind tunnels for many times when it is designed.

    Of course, the wind tunnel test was not conducted in their world, but in the world where the technology mall store that originally designed the aircraft was located.

    So as long as there is no problem during manufacturing, there will be no problem with this aircraft.

    Two days later, the door of the aircraft manufacturing workshop was slowly opened, and the long-time unseen sunlight shone into the interior of the workshop through the huge door.

    At the same time, when the sun shines on the aircraft, except the cockpit, the skin of the whole aircraft emits a dark golden light, telling the power of the bomber.

    Under the traction of the tractor, the bomber slowly left the workshop and went outside the gate. Donald and others naturally followed the bomber to the runway outside.

    When the plane was towed by a tractor to the take-off point of the airport runway, it stopped. Next to the rows of refueling vehicles on both sides of the runway, the airport staff immediately began to refuel the bomber for the first time.

    Of course, as a big guy with a takeoff weight of more than 700 tons, this aircraft needs to add a lot of aviation fuel at one time. If it is filled at one time, this big guy can add up to 300 tons of aviation fuel.

    But fortunately, this time their bomber doesn''t have to fly too far. It''s only one or two thousand kilometers, so there''s no need to fill up the oil at all. Just add a hundred tons.

    At the same time, other staff also began to move various aerial bombs into the interior of the bomber.

    More than an hour later, the refueling work of the bomber was finally completed. At the same time, more than 100 tons of ammunition were loaded. All the work before takeoff was ready to be completed and can take off at any time.
