The strongest, the fastest update of the latest chapter of the anti-Japanese beacon system!

The corners of Li Yunlong's mouth hooked up a faint smile and said: "If we want to break through the dense anti-aircraft fire network of the little devils, we will rely on our fastest jet fighter!" ”

Jet fighters?

Xiao Yan, Li Xiangyang and others don't have much concept of jet fighters, and they don't know what is the difference between jet fighters and conventional propeller fighters~!

"Brigade commander, can we use jet fighters to break through and destroy the enemy's dense firepower network?" Xiao Yan's eyes were full of shock: "This jet fighter has - so powerful?" ”

The world's first jet fighter in history was first developed by the country of Dé in 1939. The first jet fighters to be put into mass production and converted into the army were the Meteor fighter and the Messerschmitt ME-262 of the country of dé, which made the first test flight and reached a speed of 850 kilometers per hour.

However, in this parallel world, the world's first jet fighter has not yet appeared, and now only the Iron Lions have jet fighters.

You must know that the speed of propeller fighters during World War II was generally 300km/h to 400km/h, and the speed of the fastest Zero fighter was 533.4km/h.

But the speed of ordinary jet fighters has reached eight or nine hundred per hour.

Jet aircraft suddenly increased their speed to 900-950 km/h, making the aircraft successfully close to the speed of sound. However, in order to break through the sound barrier and achieve supersonic flight, it is necessary to make a qualitative change to the aerodynamic shape of the aircraft, after all, the speed of sound is 1224000m/h, that is, 1224 km/h, which still has a certain speed gap.

"This jet can reach a speed of eight or nine hundred kilometers per hour, which is much faster than the current fighter jet!" Li Yunlong said slowly: "The biggest reason why the current anti-aircraft guns can hit fighters is that the speed is too slow!" ”

"Now the fighters are all propeller fighters, and they are slow, especially when flying at low altitudes, and only long-range heavy fire machine guns can shoot it down!"

"But our jet fighters are extremely fast, which makes the little devil's anti-aircraft guns and anti-aircraft guns have no effect at all, so they can break through the little devil's air defense fire network!"

As a traversal, Li Yunlong knows very well that jet aircraft have broken through the limits of piston aircraft performance and made fighters enter another new era, especially after World War II, many countries have a considerable number of jet aircraft. Famous jet fighters include the Soviet Union's MiG-15, the United States' F-80 and Ying's "Vampire"; Most jet fighters have swept wings - to avoid the drag caused by shock waves.

Jet fighters against propeller fighters, this is not a level of competition at all, such as the jet fighter Me-262, in the first month after entering the air battle, it set a lot of records, so that 22 Allied planes were destroyed and killed, known as the "king of the air".

And Li Yunlong also knows that in the back, jet fighters have broken through the speed of sound, and the speed is beyond imagination, such as the world's fastest X-43 UAV reaching Mach 9.8, and the fastest fighter X-15A-2 reaching Mach 6.72.

Mach is equal to 12005.784 km/h.

Mach 6.72 is equal to 8,232.5376 km/h.

It's terrifying!

Jet fighters are so powerful?

Xiao Yan, Li Xiangyang and others were all stunned, they didn't expect this jet fighter to be so powerful!

Li Yunlong looked at the correspondent and said: "Immediately inform Zhao Gang and Political Commissar Zhao that the first batch of jet fighters of our army is named the Thunder Dragon Fighter, and after handling the relevant rest and recuperation work, it will immediately fly to the DPRK and enter the battle!" ”

"Yes!" The signal corps quickly went down to deliver combat orders!

The Battle of Seoul in North Korea, which will be the battle of the jet fighter Thunder Dragon fighter's fame!

Now to break through the network of anti-aircraft fire in Seoul, jet fighters are needed!

Three days later, the first jet fighters arrived in Dongdoucheon!

Dongdocheon Airport.

20 Thunder Dragon jet fighters are neatly placed in front of Li Yunlong, Xiao Yan, Li Xiangyang and so on, looking very different from the propeller fighters, the biggest feature is that there is no propeller setting!

Prior to this, Li Yunlong had already exchanged the manufacturing line and related manufacturing technology of jet fighters from the Bright Sword system, but because of modern technology, it would take a certain amount of time for jet fighters to land!

After such a long period of development, the jet fighter finally has real combat capability!

...................

Generally, it takes two to three years for a new type to be developed and possessed with actual combat capability, but the Thunder fighter only takes a few months, which is very fast!

"Brigade commander, this is a jet fighter?" Xiao Yan looked at the Thunder Dragon fighter in front of him and was very surprised!

"That's right, if we want to break through the anti-aircraft fire network in Seoul, we need 20 Thunder fighters in front of us!" Li Yunlong said with full of information: "The battle of Seoul will definitely be a sensational battle for the world!" ”

"The appearance of the Thunder Dragon fighter will definitely refresh the history of the entire air combat, which makes the little devil's Zero fighter and related combat capabilities unattainable!"

According to Li Yunlong's plan, with the development of jet fighters, the Iron Lion Army will gradually develop supersonic fighters, and gradually eliminate the current iron and blood fighters in the air to create a world's super air force!

However, this road still needs to be developed and strengthened for a long time, after all, jet fighters are still in their infancy!

While other countries are still using propeller fighters, the Iron Air Force has gradually equipped itself with jet fighters, which is definitely in the lead!
