近年术,西方国家在研制和生产新型战斗坦克中遇到了不少困难,首先是经费和时间上的困难。为了减少研制费用、加快研制速度并降低最终生产成本,一些国家曾走上了联合发展道路。但是,至今尚无一例成功。目前,只有西德和法国联合设计九十年代坦克的项目还在进行。然而某些迹象表明,达个项目也是注定要失败的。因此,各国又不得不走各自发展 In recent years, the western countries have encountered many difficulties in developing and producing new type of battle tanks. The first is the difficulty in funding and time. In order to reduce development costs, speed up development and reduce final production costs, some countries have embarked on a road of joint development. However, no one has succeeded so far. Currently, only the joint project of West Germany and France to design tanks for the 1990s is still under way. However, there are some indications that reaching a project is doomed to failure. Therefore, all countries have to go their own way
