Now that the fuel and credits have been settled, the formation of an aircraft plant should also be on the agenda. According to the development of the situation in the world, in another month Germany will launch an attack on Poland, and the artillery fire of World War II will fully ignite the whole of Europe; In another year, the Soviet-German war broke out, and two years later, the Pacific War broke out, and time was running out for him.

According to the classification of fighter performance, after the first fighter was launched in 1903, it can be roughly divided into several stages of development. In the first stage, during World War I, fighter aircraft were transformed from auxiliary units that guided artillery firing, reconnaissance, and bombing over the battlefield to independent arms used to obstruct enemy aircraft from carrying out the above tasks and form aerial confrontations.

This period was also a critical period in which the fighters were fought, as well as the typical arrangement, did not have a front-mounted machine gun, but only the shooters in the back seat fired at each other in the air with pistols, rifles and machine guns. In 1915, the German Fokker aircraft equipped with a firing coordinator completely broke the shackles of the original fighter plane, its machine gun was fixed to the nose of the fuselage, and fired through the rotating surface of the propeller in the nose without the bullet hitting the rotating blade.

In this way, the shooter in the back seat was eliminated, and both the flight and the shooting were done by the pilot. The appearance of such aircraft has fundamentally changed the way of air combat and increased the air combat capability of aircraft. From this point on, the typical arrangement of fighter weapons was established. By the end of the First World War, the fighter jets of the major countries in the world at this time could basically reach a maximum flight speed of 200 km/h, an altitude of 6,000 meters, and a weight of about 1 ton. Famous fighters at that time included the German Fokker D and E, the British S.E.5 and the French Spad.

The second stage was during the Second World War. At this time, the maximum speed of the fighter was 700 km/h, the flight altitude was 11 km, the weight was 6 tons, and the piston aero engine used was close to 1470 kilowatts. Weapons were developed from machine guns to 20 mm cannons and air-to-air rockets. The sighting system already has a gyro-optical sight that can be used for pre-quantity calculations. Famous fighters of this period include the British "Spitfire", the American P-51, P-47, F4U, F6F, the Japanese Zero and KI-43, the Soviet Yak-3, La-5 and the German Bf-109 and Fw-190.

The third stage was the end of the Second World War. At this time. Jet fighters generally replaced piston fighters, and their flight speed and altitude increased rapidly. The flight speed is close to the speed of sound, the flight altitude is 15,000 meters, and the weight of the aircraft is about 6 tons. Engine thrust 29420 N. Airborne armament has been developed to more than 20 mm cannons. A radar rangefinder is installed in the sighting system. The more famous fighters of this period include the MiG-15, F86 and so on.

The fourth stage is after the 60s of the 20th century. At this time, due to the improvement of the shape of the aircraft and the use of other advanced techniques, the speed of the fighter plane quickly broke through the sound barrier, and the armament of the fighter aircraft has developed from cannons and rockets to air-to-air missiles. The most famous fighters of this period are the American F-104 and F-4. Soviet MiG-21 and French "Mirage" III, etc.

Later, with the advancement of technology, fighter jets were also constantly upgraded, and various countries divided their domestic aircraft into generations. Standards vary from country to country, so they cannot be compared. However, the jets of the third stage are roughly similar in performance to the first-generation fighters of various countries, and the fighters of the fourth stage are not about the same as the second-generation fighters of various countries.

These stages of aircraft can also be divided into subsonic aircraft and supersonic aircraft according to their different flight performance, the first, second, and third stage fighters are all subsonic aircraft, the first stage is a low-speed aircraft, the second stage is a central subsonic aircraft, and the third stage is a high-subsonic aircraft.

As far as Chen Feng knows, the Japanese army's Zero fighter has already been produced, so if we want to completely defeat the Japanese Air Force in the air, the fighter must be more advanced and more powerful than the Japanese Zero fighter if the quality of the air force is not superior.

Japan's Zero fighter is one of the best fighters in the second stage, and this fighter has an absolute advantage on the battlefield as soon as it appears, creating a brilliant record of 30:0 in the first battle of Bishan. In the Pacific theater, Japan's Zero fighter also made the US Navy and Air Force suffer, so it was extremely important to choose which fighter to deal with the Japanese Zero fighter.

Chen Feng carefully inquired about the aircraft produced by various countries after the second stage, and found that the vast majority of fighters in the second stage were not as good as the Japanese Zero fighters, and even if there were a few models with better performance than the Zero fighters, they could not achieve an overwhelming advantage, so Chen Feng decisively skipped the fighters in the second stage.

The fighters of the third stage have no problem at all to deal with the Zero fighter, but there are some other problems, that is, the fighters at this stage are all produced by the United States and the Soviet Union, and their performance is very close to that of modern fighters, and the operation is very complicated.

After thinking about it, Chen Feng decided to exchange the fourth stage of China's Chinese-made J-5 and J-6 models, J-5 is an imitation of the Soviet MiG-17 fighter, and J-6 is an imitation of the Soviet MiG-19 fighter, both of which are Chinese generation fighters, although they are imitations of Soviet fighters, but after improvement, they are very suitable for Chinese pilots to fly, so Chen Feng took a fancy to these two fighters.

But whether to exchange J-5 or J-6 Chen Feng is worried, in terms of price, J-5 is more cost-effective than J-6, a J-5 production line with a monthly output of 200 fighters only needs 12,000 points, but J-6 needs 18,000 points. But in terms of performance, the J-6 is much more advanced than the J-5, and the price is worth the price, which really makes it difficult for Chen Feng to choose. In the case of limited points, Chen Feng decided to exchange 1 J-5 production line and 1 J-6 production line first.

In addition, Chen Feng also wants to exchange for a bomber production line, a transport aircraft production line and a helicopter production line, among which the bomber is the most entangled by Chen Feng, whether it is a tactical bomber or a strategic bomber, its production line is very expensive, especially strategic bombers.

According to Chen Feng's agreement with the US government, the United States will provide more than 1,000 B10 Martin bombers for the Northern Air Force within two years, and more than 400 have been delivered now, which is enough for the time being. So what Chen Feng lacks now is a strategic bomber.

However, the price of the strategic bomber really made Chen Feng feel crazy, and Chen Feng's favorite domestic H-6 strategic bomber had a production line of up to 46,000 points each, which made Chen Feng feel scared. Before and after World War II, the United States and the Soviet Union had some relatively good strategic bombers, such as the B-29, B-47, B-50, and B-52 of the United States, and the Tu-4, Tu-16, Tu-95, and Tu-22 of the Soviet Union.

In the end, Chen Feng still chose the relatively cheap Soviet B-47 strategic bomber, and even this strategic bomber, which is far behind China's H-6, consumed Chen Feng 22,000 points.

The price of the transport aircraft is not cheap, Chen Feng chose the American C130 Hercules transport aircraft, and the price of each production line is 18,000 points.

The first helicopter in history was successfully developed on September 14, 1939 by the American-Russian Sikorsky, and it is still a full month and a half away, and there is no shadow of the helicopter participating in the actual battle.

Although the combat effect of the armed helicopter is far weaker than that of the fighter plane, and the bombing effect is even less than that of the bomber, the helicopter also has its own advantages. First of all, the helicopter flies at a large speed, with a maximum speed of more than 300 kilometers per hour; secondly, the helicopter has flexible response and good maneuverability; Once again, the helicopter can fly close to the ground, with good concealment and strong survivability; The last is that the helicopter's airborne weapons have high lethal power and can effectively kill and injure ground targets.

Based on these advantages, the role of helicopters in local wars cannot be ignored, it is a very effective weapon against tank and armored targets, in some local wars, armed helicopters have achieved great results in anti-tank operations. In addition, helicopters are also the main fire support weapons to cover transport planes and transport helicopters for landing, so they must be had.

There are countless types of advanced armed helicopters in the world, but Chen Feng's favorite is China's Wuzhi 9, although the performance of Wuzhi 9 cannot be compared with Wuzhi 10 and foreign helicopters such as Longbow Apache and Little Antelope, but this is Chen Feng's most familiar and favorite helicopter. This helicopter can be used for personnel transportation, offshore support, sea rescue, aerial reconnaissance, close fire support, anti-tank, search and rescue, anti-submarine, reconnaissance and school guns, and communications. At the same time, it can also be used as a carrier-based aircraft, which is simply a kind of jack-of-all-trades fighter.

The most important thing is that its price is not high, plus the supporting weapons and ammunition production line, the price of a Wuzhi 9 helicopter is only 15,000 points, so Chen Feng did not hesitate to exchange for a Wuzhi 9 production line.

Putting the selected fighters together, Chen Feng couldn't help but smile bitterly, grandma's, it's just 5 production lines, and she asked him for 85,000 points, it's too dark!

However, this is also relatively speaking, 85,000 points into money is only 850 million US dollars, even if the purchasing power of the US dollar is far higher than that of later generations, but the value of 5 aircraft production lines for Chen Feng is far from being comparable to hundreds of millions of US dollars, not to mention 800 million, even if it is 8 billion, 80 billion cannot be compared, and there are also a large number of weapons and equipment production lines, this price is actually far from as high as Chen Feng expected.
