Carl slapped his face and shouted, "Good! You can say that again! Philip, you Vulcan cannon is another revolutionary artillery! I really can't see through you. Nielsen, what do you think of this idea? ”

Nelson shook his head and said: "Although what Philip said has some truth, I still firmly believe that large-caliber anti-aircraft artillery is the direction of future development." There are three main types of tubes used in artillery: impact initiation, timing initiation, or altitude initiation. To shoot an air target with a shell detonated on impact, the shell must hit the target directly. But it is difficult to hit a small, fast-moving air target at high altitude. Only rapid-fire small-caliber guns against low-altitude and low-speed targets were used for impact initiation. ”

"Most anti-aircraft guns use timed or altitude-based detonation shells. Generally, the effective killing diameter of the explosion of anti-aircraft artillery shells can reach tens of meters, so as long as the shell explodes near the target. To use altitude or timing detonation, it is necessary to accurately calculate or predict the height of the target, and set the detonation time or height of the shell before firing. If the setting is wrong, the shell will be invalidated due to premature or late detonation, even if it is accurately aimed at the target. Because of the low chance of hitting, anti-aircraft guns that use timed detonation must fire a large number of shells, creating a barrage of shells where the target may pass. Therefore, I believe that only large-caliber anti-aircraft guns will play a key role on the battlefield in the future, and small-caliber anti-aircraft guns are difficult to complete the interception task for high-speed moving targets because the power of the shells is too small, especially when the distance is very long. ”

Nelson's words made Carl feel very reasonable, what to do? One is an old expert with decades of experience in weapon design, and the other is a young genius in weapon design, and they both have their own truths, which is why the boss Carl is a little confused.

Philip took Nelson's words and said: "Mr. Nelson, I understand what you said, it is true that with the current level of anti-aircraft artillery technology, large-caliber anti-aircraft artillery still has its irreplaceable role. However, the main purpose of the current large-caliber anti-aircraft weapons is to allow dive bombers to drop bombs at high altitudes as much as possible, and torpedo bombers to drop bombs as far as possible, so as to reduce the hit rate of bombs and torpedoes. In fact, it is only by fighters that really have air supremacy. As far as ground-based air defense weapons are concerned, in order to be accurate, in addition to relying on a large number of artillery shells to form a barrage, it is necessary to rely on the development of more advanced fuses and artillery radars, and to manipulate artillery to shoot at incoming targets through fire control radars. With high-precision shooting, anti-aircraft artillery fire was able to destroy even bombs and torpedoes dropped by the enemy! ”

Nelson's cloudy eyes flashed, and he said in a deep voice: "It is true that with advanced artillery shell fuses and artillery radars, small-caliber anti-aircraft guns can play a greater role, but are the artillery fuses and artillery radars you are talking about so easy to develop?" So before these two things, large-caliber anti-aircraft guns are the main force, and small-caliber anti-aircraft guns can only be used as a supplement. ”

Philip chuckled, "Maybe." However, large-caliber anti-aircraft artillery is too cumbersome and can only be used by large warships, not small warships and armies. I think the direction of development of shipborne anti-aircraft artillery, the first is small-caliber artillery with manual maneuvering and aiming below 40 mm caliber. The development of these guns is mainly through the improvement of the guns themselves and ammunition, as well as the improvement of handling performance, in order to improve combat effectiveness. However, the performance improvement of manually operated small-caliber guns is limited, and they can only cope with low-intensity conflicts. They can also take on limited anti-aircraft missions if they are forced to do so, but this depends on the sighting equipment used by the guns and the performance of the vehicles mounted. The second direction in the development of shipborne automatic artillery is to equip the artillery with remote-controlled turrets and radar or photoelectric gun sight commanders, which will assume the heavy responsibility of the ship's air defense. Of course, this type of artillery will still be dominated by small-caliber guns, and the large-caliber guns of ships can only be used against sea and land, and for air defense it is somewhat stretched. ”

Karl saw that the two of them were almost sparkling, so he interjected: "Two chief masters, I don't think you need to argue anymore. In this way, I decided to let the two chief divisions be responsible for the development of large-caliber and small-caliber anti-aircraft guns, and use the actual results to test the accuracy of their opinions. What do you two think? ”

As soon as Carl's words ended, Philip and Nelson replied almost in unison, "Yes, I agree!" ”

After speaking, the two realized that the other party and themselves answered at the same time, and they were exactly the same. Philip and Nelson smiled, the argument between the two just now was actually an academic discussion, and there was no personal grudge in it, and through this argument, both of them had a feeling of sympathy between heroes.

Boss Carl is naturally happy to see the two chief engineers shake hands and make peace, this kind of academic argument is a common thing, especially in the field of weapons industry, each designer has his own unique opinion, sometimes it is not possible to say who is right and who is wrong, but the personal understanding is different.

Carl smiled: "Good! Since both of them readily agreed, I hope to see their work at the Stockholm International Defense Exhibition in November. Of course, I can't ask the two of you to come up with a product in such a short time, but it's okay to come up with a preliminary design? ”

Both chief engineers nodded, and Philip replied, "Don't worry, Mr. Karl, I will not only take out the design specifications, but also make a full-size model and put it on our company's booth." ”

Carl was surprised: "Oh, full-size model? Can it be made so quickly? ”

Philip said confidently: "Mr. Karl, of course I am sure. My Vulcan cannon is not too large, and if it were a real thing, it would only weigh three or four hundred kilograms. I believe that this rotary tube cannon will definitely be a highlight of the defense exhibition. ”

Lucas said on the side: "Mr. Carr, I think this is another good hype hotspot. Just imagine, the emergence of this Vulcan rotary cannon, like the emergence of assault rifles, will trigger a revolution in the field of anti-aircraft artillery design! Why don't we let the two chief engineers publish an article discussing the design of anti-aircraft artillery in our Koo's Defense Weekly, I think this collision of design ideas will definitely attract more attention! Let our anti-aircraft artillery fire before it is developed. ”

Karl laughed and said, "Lucas is right! With all of you, I'm sure Bofors will soon be on its way to glory, and it's really exciting! Come, for a better tomorrow for our company, let's toast! Today, whoever is not drunk is not allowed to leave! ”
