As a result, the devils learned from the pain, not only designed and manufactured in advance the 150mm super-heavy anti-aircraft gun, which was unbelievably powerful and high-firing height (Note 1), but also greatly improved the new carrier-based fighter of the Navy, which was already about to be finalized, and the Type 99 fighter in service, mainly by using the two-stage supercharged jishu provided by the Americans and the Japanese-style knockoffs copied from the American "Double Wasp" air-cooled engines, which greatly improved the high-altitude and high-speed performance of these two aircraft. As a result, there were no obvious shortcomings in the performance of these two aircraft, and the two new fighters were later finalized and produced in 1940 and 1941 respectively, so they were named "Zero" and "One" according to the ancient Japanese dating method

In actual combat, the Japanese have also discovered some weaknesses of the H-1, such as its dive ability is very poor, because the body is too light, resulting in unsatisfactory dive speed, so although its excellent structural strength allows it to dive bombing, but when diving at ultra-low altitude, if the engine is not strengthened, it will be easy to be shot down by ground anti-aircraft fire because of the slow speed, and if it is strengthened, it will seriously affect the accuracy of the bombing and increase the difficulty of changing the pull up after the attack is completed.

After realizing this, the Japanese Navy, which was originally worried that the Chinese would use this super bomber against their own ships, was slightly relieved, and the Japanese aircraft also had a way to escape after being targeted by the H-1, that is, dive acceleration and detachment, although this method was severely limited by the altitude and surrounding terrain of the aircraft at that time, and there may not be time to escape in actual combat (after all, dive acceleration also has a process), and the models that can carry out high-speed dives are limited to reconnaissance aircraft, fighters and light bombers. But it's much better than the previous despair of "can't fight, can't escape".

But then again, although these shortcomings do exist, because the H-1 is positioned as a bomber, and it is also a horizontal bomber with a large bomb load, even if the devil discovers these problems, the impact is actually very limited

Although the number of H-1s was limited, and the Japanese military and civilians gradually explored some ways to reduce casualties and losses, long-range bombing of the Japanese mainland did not cause as much damage to the Japanese economy as the strategic bombing of the United States in the latter part of World War II (for example, the Great Kanto Earthquake, which caused economic losses that exceeded the total GDP of the whole country in several years, can make an industrial country break its bones). It's not that the results of the Air Force are too small. It is really that the ability of industrial society to organize, mobilize, recover and rebuild is too strong. The total number of casualties is only 10,000 or 20,000, which is even more of a drop in the bucket for Japan, which has a population of 70 million. However, the helplessness of the H-1 and the terrifying lethal effect of napalm made the Japanese all look different, and this is exactly what Hu Weidong expected to see

Under the covert fanning of the flames by the Japanese Communist Party (Note 2), the panic among the Japanese people was rapidly amplified. Many citizens fled to the countryside for fear of bombing by the Chinese Air Force. As a result, more than one-third of factories in Japan are struggling to operate normally due to a lack of employees. Even the military-industrial sector is not much better, which on the one hand greatly weakens Japan's military production capacity, and on the other hand, makes it necessary for the United States to further increase its blood transfusion. This directly led to Roosevelt's fierce criticism from Republican members of Congress, and also made him realize that the election was imminent, and everything had to be centered on this, otherwise if he was not re-elected, could he still expect his opponents to continue to carry out their strategies?

However, Roosevelt did not stop aiding Japan's economy and jishu because of this, but chose to blackmail Japan when he thought the time was not ripe to appease domestic dissatisfaction, at this time the Japanese government's debt to the United States has reached more than 1.5 billion US dollars, with Japan's current extremely limited export capacity and resources need to import a large amount of congenital insufficiency, even if it takes ten years to pay off, not to mention that Japan is still at war with China, just to maintain the current military size consumes a lot of military spending, As a result, the debt will only grow, and the U.S. government has used the debt noose to cover the many Pacific islands that Japan had seized from the Germans during World War I

The Americans wanted Marcus, Saipan, and Rota Islands close to the Japanese mainland in order to further strengthen their control over Japan and establish a perimeter defense against the Soviet Union and even the future Red China, but Roosevelt knew that he could not eat hot tofu in a hurry, so he chose to attack the Marshall Islands, Caroline Islands, and Palau Islands, which were far away from the Japanese mainland. Naturally, the Japanese authorities refused to agree, but under the dual threat of the US economic blockade and the demand for debt repayment, they still had to use the Marshall Islands, which was still only a nominally "trusteeship" of Japan, as collateral to continue to borrow and purchase various materials and equipment from the United States, and this was only the beginning.

At this time, although isolationism was prevalent in the United States, the expansion of the defense circle could enhance Americans' sense of security, so the United States generally supported this, and Roosevelt's insistence on transfusing blood to Japan was also recognized by more people. But on the other hand, the whole country of Japan is extremely angry about this, because even though Japan is in deep trouble, it is still the seventh largest industrial country and the third largest naval power in Shijie, "If we continue to retreat, the American artillery can directly hit Tokyo Bay!" Even an ordinary Japanese civilian understands very well that for a time the voice of "heavenly punishment of national thieves" filled the government and the opposition, and the Japanese did not just shout slogans, and in just a few days, a number of important Japanese cabinet ministers were assassinated, although there were no deaths because of good preparedness, but it was enough to put everyone in the Japanese top level in danger

Note 1: Due to the inconvenience of this kind of anti-aircraft gun and the difficulty of production, the output has not been able to rise, so it basically did not play any role in land air defense, but later played a significant role in the air defense of the fleet after being put on board as a high-level dual-purpose gun.

Note 2: Creating panic can speed up the end of the war and reduce civilian casualties, and the Japanese Communist Party is still very willing to do it, which is very different from guiding Chinese planes to bomb civilian houses, in fact, the Japanese Communist Party only opposes the bombing of civilians, and when Chinese planes bomb important targets such as the Japanese Imperial Palace, these idealistic "leading parties" still make great efforts (to be continued......
