As the most advanced destroyer with the largest tonnage in our country's navy, the launch of the 055 destroyer has triggered a lot of discussion. The most controversial one is the 130 mm caliber main gun on the destroyer.
html Is one main gun enough on a 40,000-ton ship? How powerful is the main gun of the 055 destroyer? Is it really worthy of an artillery battalion ?
Before the missile was invented, one main gun was definitely not enough for large ships. Not to mention a "10,000-ton cruiser" like the 055 destroyer, even a cruiser with a displacement of more than 2,000 tons, such as the Hai Rong, must be equipped with three main guns and a dozen other naval guns. .
This is very common, because until the and period of World War II, people often used the caliber and number of naval guns to judge the combat effectiveness of a warship. It was not until 1960 that the world's first anti-ship cruise missile came out, and only 4 of them sank a destroyer. Only then did people realize: "Oh, it turns out that quantity and caliber are useless, missiles are the right answer."
So for a long time to come, the status of naval guns was reduced to dust. Some countries even only wanted missiles when building warships, not naval guns.
After some time, people realized that missiles were expensive and not flexible enough to use. Coupled with the new development of naval gun technology, people pulled out naval guns again. However, the naval guns during this period only played an "embellishment" role and could only be regarded as a supplement to the missiles, so basically only one or two naval guns were installed on a warship.
This is actually the case with our country's 055 destroyer, but our country's 055 destroyer has its own "specialities", which we will talk about later.
Generally speaking, one or two main guns installed on a warship are completely sufficient. Although will only install one or two main guns, since there are three different types of modern naval guns, everyone will have different choices of main guns.
Some warships will choose to install the kind of fast-firing but low-power type of archery artillery that is mainly aimed at small water targets and air targets. Some warships will choose to install the kind of that has a slow firing rate but high power, mainly for large ships. In addition, some warships will choose to install the with "medium" fire rate and power. This kind of naval gun is relatively mediocre in all aspects. The advantage is that it has no obvious shortcomings.
Like my country's 055 destroyer, it actually belongs to the second type above. But we have also said that it has special characteristics. The special characteristics of are reflected in its not slow rate of fire, and its ability to defend against air and target water targets is also very strong.
The main naval gun used on my country's 055 destroyer is called HPJ-45 130mm naval gun. This naval gun is an original product of our country, but the technology first came from Russia. At that time, our country bought the 956 modern-class destroyer from there. This destroyer was equipped with two AK130 naval guns . The naval gun is also good, but it does not meet our country's expectations, so our country added its own research on this naval gun and finally created our above-mentioned product.
HPJ-45 The first application of the 130mm naval gun was not on the 055 destroyer, but on the 052 destroyer. However, the displacement of the 052 destroyer was limited at that time, and the staff could only reluctantly carry out " Castration” finally achieved the goal.
It was not until the 055 destroyer with a displacement of 12,000 tons came out that the full version of the HPJ-45 130 mm naval gun came into use. The naval gun is powerful and has a slow rate of fire. Therefore, while having the ability to hit water targets, it also has air defense capabilities, which is very good.
In this area, the United States is not as good as ours. Their mk45 naval gun is not only troublesome to reload, but also has an extremely low rate of fire, only about 20 rounds per minute. It is completely powerless against air targets. The only advantage may be that It's lighter. However, since one main gun of the HPJ-45 130mm naval gun can hold up two others, there is not much difference in weight.
my country's HPJ-45 130mm naval gun can fire 40 rounds in one minute, and its rate of fire is twice that of the American mk45 naval gun. In addition, it adopts a dual-channel ammunition supply system and can quickly and automatically change ammunition. Therefore, the HPJ-45 130mm naval gun is quite powerful from the perspective of performance and convenience.
Some people even say that one HPJ-45 130mm naval gun can be as powerful as an artillery battalion. Do you know what is going on?
It turns out that, looking at the American Stryker artillery battalion, there are about 18 howitzers in a battalion, and the rate of fire of each howitzer is about two rounds per minute. In other words, within one minute, this artillery battalion can fire a total of 36 shells, which is not as good as the HPJ-45 130mm naval gun's forty shells per minute, so it is not an exaggeration to say that the two are offset.
With the development of the times, our country’s military strength has also made vigorous progress. The HPJ-45 130mm naval gun is the best example. We also believe that our country’s military strength will become stronger and stronger in the future, and our country will become stronger and stronger. The better come.
