Is it true that the US military took off and landed from Chengdu Airport to bomb some cities in Japan during World War II?

During World War II, American bombers did station in some airports in Sichuan and used this as a base to carry out strategic bombing on Japan.

At the beginning of 1943, according to the agreement between China and the United States, China, funded by the United States, was responsible for the expansion of some bases near Chengdu, as the US military bombed Japanese troops in China and strategically bombed Japanese frontline base. Among them, Xinjin, Qionglai, Pengshan and Guanghan airports are built as bomber bases, while Deyang and Wenjiang are built as fighter bases. At that time, the National Government completed the airport construction in Sichuan Province according to the agreement. Among them, Xinjin Airport became the largest military airport in the world during World War II, and even the United States was no bigger than it. At the end of 1943, American bomber units were stationed at the above-mentioned airports, including the 40th Bomber Brigade of the US Army 14 Air Force in Xinjin, the 462nd Brigade in Qionglai, the 468th Brigade in Pengshan and the 444th Brigade in Guanghan.

B29 and 1944, which my friends upstairs said participated in the bombing of Japan on June 5, actually took off from airports such as Xinjin, and both belonged to the 20th Air Force of the US Army reorganized by 1944. * * It is equipped with 150 b29, directly under the United States Army Aviation Command, and its air force commander is Ulf. The bombing target was indeed the steel plant in Hachiba City, Japan's then steel center. This bombing is the second bombing of Japan after the United States declared war on Japan (Doolittle's B25 took off from an aircraft carrier for the first time), and it is also the first time that the US military took off from a land base to bomb Japan.

If you search online, you can find that the so-called "Hump Bombing Japan" quoted by friends upstairs does not actually exist, and the entry of "Hump Bombing Japan" basically comes from the same reportage version ("B-29 took off from Kolkata base again, and the ground crew waved their hats to greet the pilots and watched these flying warriors gradually disappear into the sky." The ubiquity of this passage is enough to prove), because the author of this reportage actually doesn't know much about the history of World War II, and there are many fabrications. In fact, during World War II, the US military used B29 to take off from land and bomb Japanese territory. At first, they all came from airports such as Xinjin near Chengdu, Sichuan. In the "Hump Bombing" organized by India, the bombing targets were all Japanese war zones except Japan, including parts of China. For example, the first bombing of Japan by B29 took off from India and bombed the train height field in Bangkok, Thailand.

According to common sense analysis, after 1943, Xinjin Airport around Chengdu is not only the largest military airport in the world, but also has a perfect operation guarantee system, which can accommodate more than 100 B29s. Moreover, the distance from Chengdu to Tokyo, Japan is 3400 kilometers (not too close to Hachiba City), which has greatly exceeded the operational radius of B29s (the maximum is 2896 kilometers). Then, what is the need to take off from India, risk jumping over the hump, and then take off from Chengdu to bomb Japan after causing a lot of fighter losses?

In reality, the most famous battlefield aviation operation in Asia, and the biggest loss is not the "hump bombing", but the "hump route". At that time, all the coastal cities in China were occupied by the Japanese army, and the Yunnan-Myanmar highway in the southwest was cut off by the Japanese army. American aid to China and operational support to Japan all depend on the air route from India through the Himalayas, and all the fuel, ammunition and spare parts needed for B29' s bombing against Japan are also transported through this air route in Golve. The biggest loss on this route is not B29, but a large number of C46 and C47 transport planes.

Because the bombers taking off from Chengdu can only reduce their bombs because of the influence of the combat distance, and they will also be interfered by Japanese planes when they pass through the Japanese-occupied area in eastern China, after the US military occupied Mariana, the B-29 began to evacuate China on 1945 and redeployed to the US military base in Mariana. The bombing of Japanese mainland from China airport is over.
