有史以来最致命的坦克是什么?什么是坦克,它们来自哪里?我们使用地球上最好的坦克,美国制造的艾布拉姆斯M1A2来回答这个问题。这确实是今天的坦克。它与计算机,最先进的检测和通信系统完全集成。即使在夜深人静时,它也可以在数英里外发现并杀死猎物。尽管采用了现代电子技术,但其设计仍基于上世纪初提出的思想,即机动性,火力和装甲。这三个特征必须保持平衡,装甲过多或枪支太大,并且太重而无法移动,太少并且可以移动,但容易受到敌人射击的伤害。我们将研究Abrams坦克的设计从诸如俄罗斯T34的WW2坦克中学到了什么,以及它如何成为地球上最致命的坦克。但是它仍然与90年前的亲戚共享所有主要特征。它是根据WW1-确立的原则设计的,在机动性,装甲和机枪之间取得平衡。What is the deadliest tank ever built? What are tanks and where do they come from? We answer this using the best tank on the planet, the American made Abrams M1A2. This truly is a tank of today. It is fully integrated with computers, state of the art detection and communication systems. It can detect and kill its prey from miles away even in the dead of night. Despite its modern electronic technologies its design is based on ideas developed at the start of the last century - mobility, firepower and armor. These three features must be balanced, too much armor or too big a gun and it will be too heavy to move a round, too little and it will be mobile but vulnerable to enemy fire. We investigate what the design of the Abrams tank has learnt form WW2 tanks like the Russian T34 and how it has become the most deadly tank on the planet. But it still shares all its main features with its relatives of 90 years ago. It is designed on a principle established in WW1- the balance between: Mobility, Armor and Gun.
