Such an unworthy Japan did not deserve to be an ally of the Third Reich, and it was better to join forces with China than to form an alliance, because China had abundant resources, sufficient manpower, and vast depth, and these three points were also not possessed by Germany. However, what bothered the mustache was that the increasingly powerful Red Party had irreconcilable ideological contradictions with the Nazis, and the two sides could only use each other, but it was almost impossible for them to become allies. In other words, although the Red Party still tried its best to hide its strength in propaganda, with the Germans' deep understanding of the mobilization ability, they only had to go to the base area casually to estimate the maximum strength that the Red Party might mobilize, which was definitely not less than the soldiers and horses under Chairman Chiang

The Japanese are not stupid, naturally know how much impact these two setbacks have had on their international status, and it is impossible to completely reverse the adverse effects, but if they can recapture Qingdao, at least the face will always look better, and more importantly, the performance of the two Nagato-class battleships in the previous battle "indestructible" made the Japanese base camp retain a little confidence, and they believe that as long as these two giant ships are still there, the enemy will definitely not be able to hold the coastal city of Qingdao

On the other hand, although the North China Air Corps won a brilliant victory, it also paid a heavy price, losing nearly 100 planes in its own flight division alone, among which the Mitsubishi Type 96 land medium attack aircraft suffered the greatest loss. A full 33 planes were dispatched, but only 6 of them came back, of which the 25 carrying torpedoes were almost completely wiped out, Hu Weidong deeply blamed himself, knowing that the danger of the torpedo bombing mission was so high and the difficulty of Jishu was so great, he would rather let these planes carry aerial bombs, even if the battleship could not be sunk. It is also possible to blow up a few cruisers and destroyers on the premise of relatively small losses, which is better than letting those pilots die needlessly

Indeed, aerial bombs are not as powerful as torpedoes. However, the probability of being shot down by anti-aircraft fire when dropping bombs is much smaller, and although 24 of the Type 97 heavy bombers risked lowering the height of their bombs, the Devil's large-caliber anti-aircraft guns did not have fire control radars or proximity fuses. The hit rate was really not good, and the planes only launched one attack, dropped the bomb and returned straight back, so the loss was only a third, although it was not small, but it was still much better than the torpedo bombers.

As for the seemingly dangerous dive bombing, the large-caliber anti-aircraft guns without the proximity fuse of the shells were basically ineffective, and the extremely fast dive speed greatly reduced the hit rate of the enemy's small-caliber anti-aircraft guns and anti-aircraft machine guns, as long as they were not entangled by the enemy's fighters. In fact, the battle loss rate is generally not too high, especially the 96-type 25 anti-aircraft guns on the devil ship, especially the combined and especially triple type, which is a rare wonder in the history of the development of anti-aircraft guns, as long as they are not hit by their first round of shooting, they can almost be completely ignored in the subsequent battles. Therefore, there are not too many planes that were directly shot down by devils during the dive bombing process.

However, because the Soviet-based SB3 bomber and the Mitsubishi Type 96 land medium attack aircraft were not specialized dive bombers, many pilots, especially the guys of the Soviet aid air force, took the risk of diving and dropping bombs at a large angle close to vertical in order to improve the hit rate, but in the process of changing (pulling up), most of them were damaged to varying degrees because of the insufficient strength of the airframe, and even disintegrated, so the losses of these two bombers naturally increased a lot. In addition to the Mitsubishi Type 96 land medium attack aircraft already mentioned above. The North China Air Corps lost a total of 21 Soviet-made SB3 bombers, 7 Mitsubishi 97 light bombers, and 6 Kawasaki 98 light bombers, which is really not a small amount, and Hu Weidong also came up with the idea of introducing authentic dive bombers

Although those fighters are equipped with aviation rockets for long-range attacks, in order to ensure the hit rate, the pilots often rush to a distance of 1,500 meters, or even within 1,000 meters, not to mention anti-aircraft guns, even anti-aircraft machine guns can pose a deadly threat to these fighters, so the losses are also quite large, especially the slower Type 95 biplane fighters and the Soviet I16 fighters that were attacked by devils first, according to post-war statistics, the North China Air Corps lost a total of 34 Type 95 biplane fighters. There were 6 Nakajima Type 97 fighters, 7 Type 96 carrier-based fighters, and 29 I16 fighters, and if you count those bombers, the total number has reached a full 137. The only thing that made him feel fortunate was that his repeated emphasis on it had finally had some effect, and there were not too many pilots as impulsive as Yan Haiwen, and now it was at least possible for him to save dozens, if not hundreds, of pilots through the exchange of prisoners of war (it is unknown how many pilots parachuted and how many of them were rescued by enemy ships). Otherwise, the loss this time will be even greater

But even so, it is obvious that the North China Air Corps, which has already broken its muscles and bones, is no longer suitable to be sent out to carry out bombing missions immediately, not to mention that now that the aviation torpedoes have been used up, there are only 12 Type 97 heavy bombers that can carry 2 tons of super-heavy bombs left to use, considering the pitiful hit rate of horizontal bombing, it is considered lucky to be able to hit one or two shots, and only one or two aerial bombs, even if they weigh 2 tons, are not enough to blow up and sink the Nagato-class battleship

As Shijie's No. 1 ammunition expert, Hu Weidong couldn't help but think of his old business, "In the case of aerial bombs, unless you use penetrating warheads (commonly known as ground-penetrating bombs) and rely on the impact force of falling from high altitudes to drill into the deck and explode, it is possible to effectively deal with such giant battleships."

Hu Weidong had participated in this research before crossing, and he was also one of the most important Jishu leaders, whether it was the bomb structure, or the formula and process of related materials, all of them were well understood, and only some experiments were needed to make a basically qualified penetrating warhead, although the penetration power may not be as good as the original version of later generations, but the deck of the battleship could not be compared with more than ten meters of concrete. Although in the absence of a guidance system, the hit rate of the penetrating bomb must be miserable, but compared with the cost of the battleship, even if it is a few hundred bombs for one, it is definitely a big profit, not to mention that even if it is a high-altitude bombing, no matter how bad the hit rate of one percent is definitely there, and with the improvement of optical sights and bomb delivery computers, it is not impossible for the hit rate of 4000-meter bombs to reach 10% (in the case of a battleship) ......)
