readx; The Americans did not get into a big deal because of a Chinese exercise announcement, and although the Chinese exercise announcement caused a great deal of confusion, the Americans were also sitting on an emergency deployment, and a large number of the main fighters of the Army Air Force were quickly deployed to Alaska and Canada. Among them www.biquge.info there are not only the P51 and P47, the two main propeller fighters of the US Army Air Corps, but also the P80 jet fighter, which has just been in service for less than a month.

The American P80 jet fighter was successfully first flown last year, using the J33 centrifugal engine of General Electric, and the thrust of the modified engine has reached 4,000 pounds, that is, about 1,800 kilograms, the J33 engine is the Whittle centrifugal jet engine technology obtained by the United States from the United Kingdom, which was developed after imitation and improvement by General Electric, and the prototype of J33 GE1-A was only 1,250 pounds of thrust at the beginning. However, after General Electric's vigorous improvement to the J33 finalization, it has reached 4,000 pounds of thrust, and its development speed is not not slow, and from this point it can be seen how strong the basic industrial heritage of the United States is. ，

Although General Electric's J33 engine is not as good as China's current jet engine in terms of surname, the gap is not too big, and the P80 equipped with the J33 engine reached a maximum speed of more than 800 kilometers during the test flight.

Since Germany, China and the United Kingdom have all entered service and equipped with jet aircraft, the United States naturally did not dare to lag too far behind, so it was impossible to wait to place orders for thousands of aircraft, and in early February 1945, the first batch of P80A fighters of the Army Air Corps was officially delivered.

Although the United States P80A and China's F10 and Germany's ME262 are roughly at the same level, there is still a huge gap from China's latest F12A, not to mention that China is already ready to enter service with a more advanced F12B, although the overall structure of F12B still uses the F12A body, but it uses the latest improved FL43-3 axial flow engine of Föhl Electric. Its thrust has already increased from two thousand kilograms of FL43-2 to two thousand four hundred kilograms.

In the comparison of jet engine research and development between China and the United States, China is early in development, relatively mature, and has been taking the road of small steps and fast running, while the United States has sufficient technical background, although the research and development time is late, but with a strong technical background and industrial foundation full of stamina.

No matter what the era, in fact, the air force competition of various countries is compared to an engine, and if the engine is good enough, even if the plane is turned into bricks, it can be made into the sky.

The United States has now deployed all the P80s that have just entered service to the newly established North American Air Defense Command, which shows how much of a threat China's ultra-long-range bombers pose to them.

The current Americans have high hopes for a large number of fighter planes deployed in the north, especially the P80 fighters, hoping to intercept the bombing bombing that China may launch on the east coast of the United States in the next few days.

On the afternoon of February 187, 1945, in a secret air base in the middle of a piece of ice and snow in northern China, many tracked snow plows were clearing the snow on the runway of the airport, and on the edge of the runway, several huge B19 bombers were already being dragged out by giant trailers in a huge row of hangars.

The commander of the 101st Wing, Lieutenant General Fei Qingke, was wearing a thick general's coat, looking at the three Pang **19 bombers that arrived on the runway one after another, and his mood couldn't help but be excited!

As the supreme commander of the 101st Wing, Lieutenant General Fei Qingke is not a well-known person in the people or even in the Air Force, not only do few people know him, but even fewer people know the 101st Wing, which is the only B19 bomber wing in China, and its four subordinate combat groups have a total of more than 80 B19 bombers, which have been slowly accumulated by the Air Force in the past few years.

In the past few years, due to the need for secrecy, not only did the number of the 101st Wing not appear on the establishment of the Air Force, but even many high-ranking military generals did not know that China already had ultra-long-range bombers that could bomb the United States.

And now a few years have passed, in order to deter the United States, in order to achieve the strategic goal of surrendering without a fight, and in order to obtain greater post-war benefits, China has not hesitated to take out the two major weapons of the town: nuclear bombs and intercontinental bombers! Once these two are combined, it will definitely be an invincible weapon in the world!

Watching these three huge B19 bombers slowly enter the runway, and then these three behemoths with a maximum take-off weight of up to 160 tons began to start their huge four liquid-cooled piston engines, and then drove the huge propellers to start rotating, and it didn't take long for the speed of the propellers to reach an unclear level, and at this time a B19 bomber in front began to taxi, and the speed was not fast at first.

In order to achieve a larger range, the engine power of the B19 bomber is actually not very high, and it needs to be accelerated with a very long runway when taking off with full load in order to lift off, and the speed of climbing altitude after liftoff is also very slow. The only commendable thing about the B19 bomber is that the high-altitude cruising speed is relatively fast, but the maximum speed is not fast, the maximum speed at high altitude is only 650 kilometers, and the fuel consumption is very large at this speed, which will seriously affect the range, so according to the B19 flight manual, if there is no absolute necessity, then do not reduce or increase the speed, you must maintain the optimal cruising speed, so as to achieve the design range.

After watching these three B19s rise into the air one after another, Lieutenant General Fei Qingke ordered the nuclear bomb carrier aircraft to be ready, and the escort F5E fighters were also ready to take off.

In the era when there were no satellites, it was also troublesome to carry out nuclear bombing, and it was necessary to send meteorological reconnaissance planes in advance to conduct meteorological reconnaissance of the target area, and at the same time find the accurate target area for bombing. After all, nuclear bombs are so expensive that they can't be thrown around, and if they are thrown out of the place, it will be a big loss, not to mention that the political influence of China's nuclear bombing of the US coast this time is too great, and if the plane deviates for dozens of kilometers and accidentally throws it in New York or other places on the US mainland, it will really trigger a global war between China and the United States.

Therefore, although China only intends to drop a nuclear bomb on the high seas off the eastern coast of the United States, it will send more than nine B-19 bombers for this purpose, and the first six are reconnaissance planes, which do not carry nuclear bombs, but carry a large number of meteorological gathering equipment, aerial photography equipment, and communication equipment. After arriving at the target sea area a few hours in advance, collect local meteorological data and transmit this information back to the nuclear bomb carrier aircraft in the rear. If the local meteorological conditions are good and the conditions for dropping bombs are met, then the mission will continue and the bomb will be dropped, and if the weather conditions over the ground are complicated to drop the bomb, then the mission will be terminated and the mission will be returned, and another time will be chosen to continue the mission.

When China's six B19 bombers took off one after another, they slowly climbed one after the other, and finally reached an altitude of 15,000 meters to cruise at a speed of 500 kilometers per hour.

As the hour passed, at a radar station in Alaska, the officers and men of the American radar, who had been ordered to keep an eye on any plane flying from the Arctic Ocean two days ago, were watching the radar display with full attention.

And suddenly a sergeant suddenly shouted: "Look, what is this?" Is it an airplane? ”

Then several nervous radar officers and soldiers walked over, and then read the data of those vague bright spots on the radar, and one of the captains frowned: "Although the distance is too far to be sure, this is definitely not a normal phenomenon, it is very likely to be a Chinese bomber!" ”

"But if they are really Chinese bombers, this flight altitude is more than 15,000 meters, how can they fly up?"

For the people of 1945, the flight altitude of combat aircraft was generally maintained at about 3,000 to 7,000 meters, and only China's B16 bombers and American B29 bombers flew to an altitude of 10,000 meters when they performed their missions, but it was only an altitude of about 10,000 meters, and it was absolutely impossible to fly to an altitude of more than 15,000 meters.

Although there were some doubts, the situation of this radar station was fed back to the North American Air Defense Command as soon as possible!

The North American Air Defense Command, its predecessor is the Air Defense Command established by the US Army in 1944, this US Army Air Defense Command is very similar in function to the Fifth Air Force of the Chinese Air Force, which is specifically responsible for domestic air defense work, and is not responsible for foreign wars. The most fundamental reason for its establishment is because of the rise of China, China said that "tens of thousands of strategic bombers in this operation showed that they are not weaker than the United States' strategic bombing capabilities, although the B11 and B16, which are widely known to outsiders, lack the ability of intercontinental bombing, but the United States still feels the pressure, so in the second half of 1944 the formal establishment of the Army Air Defense Command."

Later, as the conflict between China and the United States intensified, the United States also further accelerated the construction of air defense forces on the northern border, and due to the geographical location of the United States, the direction of possible air strikes in the United States was focused on the area from Alaska to the Arctic Ocean, but Alaska and the mainland of the United States were separated by Canada.

Although the United States and Canada both belong to the Allied Forces, but in the end they do not belong to the same country, so the United States and Canada are negotiating, requesting the two countries to jointly establish an air defense command, Canada is holding the idea of enjoying the shade under the big tree, anyway, it does not need it to pay for people, just go out of some places, so it reached an agreement with the United States at the end of 1944, followed by the establishment of the 'Allied North American Air Defense Command', and urgently deployed a large number of radars and interceptor fighters.

Since China announced two days ago that it was going to conduct live-fire exercises on the east coast of the United States, the North American Air Defense Command has entered the most urgent state, and many radars are monitoring many of the vacancies throughout North America. It has been done to the extent that it is barely covered.

Of course, this coverage does not cover the entire airspace over North America, but the airspace of some key areas.
