Shen Huan said eloquently: "These two design schemes, the choice of the caliber of the main gun, I want to discuss a question, that is, whether our new dock main gun should take into account the issue of sea and land strikes.
As Elder Li said just now, there may be almost no chance for the main artillery of Xinwudeng to exert an attack on sea and land in the future naval battle.
Although the 100-millimeter gun still has laser-guided shells, no matter how the final guidance and extended range are used to improve the land-to-sea attack capability of the medium-caliber gun, the gains outweigh the losses, and I think that the land-to-sea strike mission should still be handed over to the large-caliber main guns and anti-ship and land-attack cruise missiles of the fleet destroyers. ” "The second problem is the issue of air warfare.
Our 100-millimeter compact gun, originated in France, also uses terminally guided shells to improve the interception rate of air targets, but for terminally guided shells that require a large number of electronic components, it is too difficult to apply on ships and is not suitable for air defense.
Therefore, I also think that the 76-mm gun should have a greater advantage in terms of air defense performance, because its rate of fire and reaction speed are better than that of the 100-mm gun, it takes up less space, and its reliability is better than that of the 100-mm gun. ” "Of course, in terms of the configuration of the close defense gun, I personally think that the use of two domestic 730 close defense guns is enough.
The localized AK630 near-defense gun, although it has improved a lot in terms of reliability and shooting accuracy compared with the introduced prototype, and the reaction time is also faster, but it needs to be controlled by the shipboard fire control system, although it is light in weight and occupies a small space, but in terms of comprehensive combat effectiveness, I think it is much inferior to the domestic 730 close-in anti-aircraft gun. ” "The 730 close defense gun, because it is equipped with a small circular radar, plus its own color camera, thermal camera and laser rangefinder and other advanced fire control equipment, so it has a longer detection range for small targets, and at the same time it can also use a photoelectric system to detect the target, and at a distance of three thousand meters, the target will be shot down, and the combat reaction time is much faster than AK630, I think it is completely a top two, only need to be equipped with two 730 close defense guns, plus seven or six mm main guns, It is enough to deal with the air threat, after all, our dock landing ship is not fighting alone, but within a system, it is equipped with a shipboard weapon system, just to deal with those fish that slip through the net, two 730 and one seven- or six-millimeter gun are enough!
” After Shen Huan finished speaking, he felt quite happy!
In fact, Shen Huan felt that the performance of the domestic 730 near-defense gun was far superior to the AK630 close-in defense gun, and the domestic frigate and the new dock were installed only after considering the maturity and cost in the early days, and later they were replaced with 730 close-defense guns, and the AK630 guns were basically eliminated.
And in terms of maturity, after Shen Huan was reborn, the 022 missile boat was put into service a few years ahead of schedule, and the advanced 730 close defense gun has been replaced on the 022 missile boat, so in terms of maturity, the 730 close defense gun is not bad, although the cost of a 730 close defense gun has reached more than 30 million yuan, which is much more expensive than AK630, but it can be a top two, and the new dock is enough for only two, of course, three is not impossible, but the cost is much higher.
There are many military fans who think that the domestic 730 close defense gun is borrowed from Da Mao's AK630 gun technology, but in fact, this is not the case, the domestic 730 gun and AK630 are completely unrelated.
Because as early as the mid-80s, when the 713 Institute launched the new domestic air defense naval gun weapon system, that is, the 857 project, the military and designers unanimously refused to learn from the Damao AK630 gun design, so the two are completely different in structure.
Shen Huan was bold enough, in front of so many experts, in front of the chief engineer of Xinwudeng, he directly said such a thing, two 730 and one seven- or six-millimeter gun are enough.
So Chief Engineer Zhu Qunying also nodded frequently when he heard it, and when Shen Huan finished speaking, she couldn't help but stand up and said: "Shen Gong, I agree with your suggestion very much, in fact, we have also considered the problem of whether the two 730 close defense guns are enough, because there is a seventy-six mm main gun, which can also be air defense, but after all, our new dock has such a large volume, so we are still relatively conservative to give these two plans, in fact, after we complete the selection, we will further test and calculate, today Shen Gong's suggestion, We'll think about it seriously. ” Several leaders who came to participate in the selection meeting also nodded from time to time, and Zhao Jinfu, the director of 701, became more and more optimistic about Shen Huan.
After a pause, Zhu Qunying said, "Do you have any suggestions?"
So that we can make our new dock design better. ” Of course, no one has expressed any opinion at this time, because in fact, this question is not complicated, it is just a question of how to choose.
In the end, the design team also collected the review opinions of the experts at the meeting, and the results were amazing, most of the experts supported the use of the new 76 mm main gun, plus the domestic 730 close defense gun.
At this time, Shen Huan couldn't help but think of the original 071 type dock landing ship, the four AK630 near-defense guns that looked inconspicuous were replaced by more advanced 730 close-defense guns, indeed from the perspective of military fans, the domestic 730 is much more powerful and domineering than the AK630 small potato, of course, more importantly, the performance of the domestic 730 near-defense gun far exceeds the AK630, which is very important for improving the safety of the dock landing ship.
In fact, the later 054A frigates, in the last few have begun to be equipped with 1130 guns, and the 10,000-ton drive is ironclad will use 1130 guns, domestic aircraft carriers are also 1130 guns, the future Chinese Navy close defense guns, is these two models, 730 and 1130, at this time the new dock board uses 730 guns, that is absolutely correct, only by looking at the long term, can we design and build better warships for the navy.
The AK630 near-defense gun is structurally different from the 730 near-defense gun, the biggest difference is that one is the internal energy source, the other is the external energy, and the AK630 gun, which is driven by gunpowder gas when the shell is fired, is indeed relatively slow to reach the maximum rate of fire, which is a big problem for intercepting fast-flying small targets such as anti-ship missiles.
The 730 close defense gun, which uses external energy, does not have this fatal shortcoming, and its internal ballistic performance is much better than that of the AK630, the shooting accuracy is higher, and of course the price will be much higher.
It's just that, sometimes if you think about it, the safety of the warship is more important, and two 730 guns are not more expensive than four 630.
This is why the 054 series frigates, on the first two basic 525 and 526 ships, installed four AK630 close defense guns, and the later Type 054A were all replaced with two domestic 730 close defense guns, because the combat effectiveness of the two 730 close defense guns must exceed the four AK630 close defense guns.
Of course, for Zhu Qunying, it is not easy for them to realize this like Shen Huan, a reborn person, so when Shen Huan said that sentence, Zhu Qunying actually sweated for Shen Huan, you must know that there are so many experts at the meeting, and one or two will stand up and refute it.
