随着新技术的不断涌现,使坦克性能得到不断提高,另方面又使得坦克成本愈来愈高,这就给坦克发展带来新的矛盾。对生产坦克的国家来说,由于坦克成本上涨,对坦克的需要量大为减少,即使是比较富有的西方国家,也买不起那么多的坦克。生产厂商仅仅为本国军队生产坦克,利润将越来越少。然而,军队需要更先进的坦克,生产厂商又想获取更多的利润,所以继续发展新坦克是确信无疑的事情。坦克生产国为了缓和坦克成 With the continuous emergence of new technologies, tank performance has been continuously improved, on the other hand makes the tank costs higher and higher, which gives the tank to bring new contradictions.
