Due to the scarcity of talents in the Chinese Navy, and even a blank in many aspects, Hu Weidong was quite polite to him, a prisoner of war, and Kanazawa Masao did not refuse to cooperate like most Japanese officers and soldiers who had just been captured, on the contrary, he knew everything and said everything, Hu Weidong was naturally very happy about this, but after learning that Kanazawa Masao was from Osaka, he still couldn't help but secretly complain in his heart, "No wonder, no wonder." ”

Kanazawa Masao is not alone, and it is impossible for him not to know that his surrender will bring trouble and even danger to his family, but Hu Weidong did not see too much pain and worry on his face, so he immediately gave him a "cold nature" evaluation, but the strange thing is that Kanazawa Masao treats his subordinates quite well, and he does not like to put on a show like ordinary Japanese officers, so he is very popular with the military, otherwise he is estimated to be overthrown directly by the lower-level officers and soldiers after the order to surrender is issued. After all, the officers and men of the Japanese Navy are not as deeply poisoned by militarism as the Army, but their sense of honor is much stronger than theirs

However, Hu Weidong knew that there were everyone on Shijie, so he didn't make much of a fuss. Hu Weidong did not have much interest in what kind of person Kanazawa Masao was, as long as he could help the Chinese Navy, and Kanazawa Masao, who also understood this, quickly won Hu Weidong's preferential treatment and attention to him with his performance

Kanazawa Masayoshi didn't say much at first, but rushed to board the two Chinese simply converted warships to find out, and Hu Weidong, who was confident that the captive had no chance to escape, did not hide it from him. The functions of the ship's anti-aircraft weapons, gun-sighting radar, and even proximity fuses were briefly introduced. He was also invited to make some suggestions.

"No wonder your anti-aircraft fire is so powerful! We don't lose unjustly, we don't lose unjustly, with these things, even old ships and old guns can be multiplied, especially when radar is used in night battles, it is equivalent to a blind man with a clear eye! Masayoshi Kanazawa sighed depressedly, but in his heart he was more sure of his surrender, with the values of the people of Osaka, this kind of battle that must be lost should not be fought at all. It's just a child's play to take the lives of higher-ranking officers and soldiers! ”

Now that he had become a prisoner of the ranks, Masao Kanazawa had some consciousness of being a prisoner, and after boarding the ships and taking a general look at them, he pointed out that destroyers, on the one hand, would not be the focus of air attacks by enemy planes. On the other hand, even if they are sunk by bombing, the losses are not as large as those of large ships, so for them, it is more important to better complete the task of regional air defense than self-preservation, and large warships such as battleships, battle cruisers, and heavy cruisers are just the opposite, so Kanazawa Masao suggested that on the premise of not affecting the main performance of warships, destroyers should be given priority to large-caliber anti-aircraft guns, and those two battleships and two heavy cruisers should be given priority to be equipped with close defense weapons. Of course, Kanazawa did not mean that destroyers and light cruisers, which might be equipped with close-in weapons, or that large warships would not be equipped with large-caliber anti-aircraft guns, but that they should have their own emphasis.

As soon as Hu Weidong heard that it made sense, he happily accepted it. Of course. It also depends on the situation, at present, Shijie's naval battle is still based on naval gun shooting, in order to avoid accidental damage, the spacing between the ships is generally widened, if the fleet is larger, often the shorter range of small-caliber anti-aircraft guns can not protect all the warships in the fleet, so the role is greatly reduced; However, if the aircraft carrier group with warships close to each other or the number of warships is relatively small, small-caliber anti-aircraft guns play a more important role in the fleet's air defense system because their rate of fire and steering are much faster than those of large-caliber anti-aircraft guns. This contradiction reminded Hu Weidong of the more specialized classification of warships in later generations, although China does not have a decent shipbuilding capability at all. But this idea was secretly buried in Hu Weidong's heart

And for the caliber of anti-aircraft guns, Masao Kanazawa also has an opinion, he believes that under the same jishu conditions, for a warship, an anti-aircraft gun of 120 caliber is compared to an anti-aircraft gun of 127. Exactly the same in rate of fire, and almost the same in volume and weight. However, the power of the 127 caliber anti-aircraft gun is obviously greater than that of the 120 caliber, so it has more advantages on the whole, and the 127 caliber can be widely adopted by the navies of various countries, which is enough to show that this caliber is a classic. As for the twin 75 anti-aircraft guns equipped on the ship, Masao Kanazawa did not belittle it too much, although the 76 caliber is more classic for the navy, but after all, it is only a centimeter difference.

During the conversation, Masao Kanazawa couldn't help but complain and tell a little insider, it turned out that the Japanese Admiralty made 120 and 75, two rare anti-aircraft gun calibers in the navy, mainly to gamble with the army, otherwise the same design and materials, made of 127 caliber and 76 caliber anti-aircraft guns The comprehensive performance will definitely be better, even if the cost performance is considered. After hearing this, Hu Weidong couldn't help but be moved, in addition to what Kanazawa Masao just said, he also thought that the cost of the proximity fuse is still on the high side, so the larger the antiaircraft shell, the more economically cost-effective it is

Regardless of his current busy military affairs, he managed to squeeze out some time to design two types of field antiaircraft guns for the army, namely 88 caliber and 105 caliber, the former was used to replace the 75 anti-aircraft gun, which had no advantage in all aspects (Note 1), and the latter was set to be the field anti-aircraft gun with the largest caliber in the Chinese army in the future, and the original 120 high-level dual-purpose cannon would also be phased out one after another, because the rate of fire was too slow and the second was too cumbersome.

Note 1: The rate of fire of the 88 anti-aircraft gun is the same as that of the 75, although it is heavier and larger, but if you consider it in combination with several major truck models produced in the border area, those who can drag the 75 anti-aircraft gun in actual combat can definitely drag the 88 anti-aircraft gun, so this advantage of the 75 anti-aircraft gun does not exist. If it was before, the 75 anti-aircraft artillery also had an advantage, that is, if necessary, it could be loaded with shells used in the 75 caliber mountain artillery field artillery to shell the ground, but with the continuous increase in the production capacity of the 105 mountain artillery, the 15 th Army has completely eliminated the 75 caliber mountain artillery field artillery, so this advantage does not exist.

As for the twin-mounted 75 anti-aircraft gun, although the firepower is stronger than the single-barreled 105 anti-aircraft gun, it is also larger than it, and it is more inconvenient to maneuver, so it is better to use the 105 anti-aircraft gun or the 88 anti-aircraft gun. Even if there is a real need, because there is no need to consider the factor of mobility, it must be better than the powerful 88 anti-aircraft gun, so it is also not of much value. Therefore, no matter from which point of view, the 75 anti-aircraft gun has no value in continuing production, but because the new anti-aircraft gun will be put into production soon, it will be difficult to fully meet the needs of the rapid growth of the army for a long time, so the original 75 anti-aircraft gun should still have no problem at the end of its life......)
