Hello everyone,today i want to talk about missiles。
To be honest,I wasn't interested in military knowledge until the war between Iran and America began.
I was quite wondering whether these news are true when i saw them in short videos。
And is aircraft carrier really this weak?I deeply doubt it.
So basicly,there are mainly two types of missiles。
One is ballistic missile and the other is cruise missile。
The question is whats their difference?
The ballistic missiles are very powerful,they can fly into the space and hit the targets on different continents with super-high speed。
But they cant fly freely and hit whatever you want as you imagine。
Their fatal flaw is that their flying track is settled from the very beginning and cant be changed during the flight。
Which means they can only aim on those fixed targets and this makes it easy to predict and defend them。
That's why we create cruise missiles,to be able to change the track during its flight to hit on the moving targets。
However ,based on the movement laws of physics,if u want to change your moving directions easily,u have to lose your weight and low down your speed。
Which means in order to hit the target,cruise missiles have to sacrifice their power and can only fly with a low speed。
This feature also makes them easy to be defended。
So in general ,there is no perfect missile for now in the world。
Here comes the question,whats the probability to hit the aircraft carrier with missiles? the answer is almost impossible。
Firstly,aircraft carrier is too small compared with the ocean to be located。
You can only use satellite photos to find it。but satellite is flying fast around the earth on a fixed track,and the aircraft carrier is always moving,which means even u get the photo,the aircraft carrier is long gone。
Secondly,the defense system of aircraft carrier fleet is so strong that almost no missiles can make threat。
Even if the cruise missile really hit it,the damage created is like a stone hitting a building。
That's why we are doing our best to build own carrier fleet。 That's all.
Thank you!
大家好,今天我想聊聊导弹。
说实话,在伊朗和美国的冲突开始之前,我对军事知识并不感兴趣。
当时我在短视频里看到那些新闻,心里挺疑惑的,不知道是真是假。
而且,航空母舰真的那么脆弱吗?我深表怀疑。
简单来说,导弹主要分两种。
一种是弹道导弹,另一种是巡航导弹。
问题是,它们有什么区别呢?
弹道导弹威力很大,可以飞到太空,以超高速打击不同大陆上的目标。
但它不能随心所欲地飞行,想打哪儿就打哪儿。
它的致命弱点在于,飞行轨迹从一开始就设定好了,飞行途中无法改变。
也就是说,它只能瞄准固定的目标,这让它容易被预测和防御。
所以我们才发明了巡航导弹,为的是能在飞行中改变轨迹,打击移动目标。
然而,根据物理运动规律,如果想轻松改变飞行方向,就必须减轻重量、降低速度。
这意味着为了命中目标,巡航导弹不得不牺牲动力,只能以低速飞行。
这个特点也让它们容易被拦截。
总之,目前世界上还没有完美的导弹。
那么问题来了,用导弹击中航空母舰的概率有多大?答案是几乎不可能。
首先,跟广阔的海洋相比,航母太小了,很难定位。
你只能通过卫星照片来寻找它。但卫星是沿着固定轨道绕地球高速飞行的,而航母一直在移动,这意味着即使你拿到了照片,航母也早就跑远了。
其次,航母编队的防御系统非常强大,几乎没有导弹能构成威胁。
即便巡航导弹真的击中了它,造成的伤害也不过像是一颗石头砸在一栋大楼上。
正因如此,我们才要尽全力建造自己的航母编队。谢谢大家。
