这也给己方提供了改装的思路，如果59坦克的动力舱不够大，给它加长一些，又何尝不是一个好的改造方案呢？ 秦振华笑着点头，心中已经沉了下来。 “而对于我们坦克厂来说，这意味着更多的问题。”秦振华继续说道：“首先，炮塔增加，就意味着坦克的重量会增加，如果换上西方的炮塔，至少我们要增重五吨以上，现在四十吨级的坦克，就会增加到四十五吨，对我们的发动机，变速箱，提出了更高的要求，如果我们用更大的发动机的话，或许车体还要增加，这样下去，那就会导致整个坦克的自重飙升，可能会超过五十吨。即使我们能造出来，对我们国内的各种桥梁等等，也就提出了更大的限制条件。” “我们保证完成任务。”秦振华说道：“我们的80坦克，经过了大量的试车，已经证实了足够高的可靠性，这次的阅兵，有了80坦克的加入，才算是我们地面武装力量的一次飞跃啊。” 祝老的建议是有道理的，秦振华也郑重地点点头：“我们进行一个星期的准备，一个星期之后，我们出发！” 这并不是一笔大生意，老巴的军费是紧张的，他们只能是选择自己最合适的方案，不可能像那些大金主一般，动辄就是购买一大批先进的坦克，现有的坦克改进，也是小心翼翼。 秦振华说的很坦然。 “是的，而且，我们也计划从国外采购这种武器系统。”祝老说道。
