火控系统
M48生产型车火控系统采用体视测距仪。  
M48A2C坦克车长配有1具M13A1E1合像式光学测距仪，取代了原来的体视测距仪，最大测距距离为4400米，放大倍率为10×。炮长有1具潜望式瞄准镜和1具观察潜望镜，放 ...
兵器2004年第二期，27页。清清楚楚的写着M48A3是机械式弹道计算机。第28页则写着首批改进套件于1964年生产。

你要有兴趣我可以发照片。另外，第26页M48A2C使用了新型的M17C图像重叠式测距仪。也与你说的不同。

嘴里说鄙视百度党。需要我把百度百科的东西再贴一次吗？和你131楼毫无二致呀

论坛不让发链接，你可以用“从M48到勇虎”搜索一下。

笑话，你自己提出的东西居然叫我去找证据，你凭什么叫我找，是我说它用碎甲弹的么？91年的兵器知识，你会说怎么不会找，你不找出是哪一期哪一页？

知道碎甲弹的特点么？速度慢直射距离短易受横风影响飞行时间长 ...
说到底，原来你也是推测啊。你只考虑了初速，考虑了炮弹高速旋转的影响了吗？玩过陀螺没有？骑过自行车吗？不旋转的穿甲弹和旋转的碎甲弹比弹道，2000米以内还靠点谱。不过我估计你也没学过大学物理。
顺便告诉你一个常识，穿甲弹、碎甲弹虽然说是平直弹道，其实都是抛物线。

关于虎王的弹药，我偷个懒，让你看看维基百科的原文： Panzergranate 39/43 projectile (PzGr—armor-piercing shell), and 238 and 153 mm (9.4 and 6.0 in) for the PzGr. 40/44 projectile between the same ranges. The Sprenggranate 43 (SpGr) high-explosive round was available for soft targets, or the Hohlgranate or Hohlgeschoss 39 (HlGr—HEAT or High explosive anti-tank warhead) round, which had 90 mm (3.5 in) penetration at any range, could be used as a dual-purpose munition against soft or armored targets.[17]
咱们数一下：
Pzgr39/43,Pzgr40/44,Gr39，这你我都认同。spgr43呢？你是该学学小学数学还是认为维基百科帮我撒谎？

关于M48，我也照抄一下维基百科：
M48: Differed from the M47 in having yet another new turret design and a redesigned hull, doing away with the bow machine gun position, featuring the M41 90 mm gun. These turrets give the M48 its distinctive non-M26 style look. Originally the gun featured a Y-shape muzzle brake, but this was changed to the more characteristic T-shape.
M48C: Over a hundred original production hulls were found to be lacking correct ballistic protection and were relegated to training as the M48C.
M48A1: New driver hatch and M1 commander's cupola, allowing the M2HB .50 caliber machine gun to be operated and reloaded from within the vehicle.
M48A2: improved powerpack and transmission, redesigned rear plate, and improved turret control.
M48A2C: M48A2s with an improved rangefinder, M17, new ballistic drive and bore evacuator for the main gun, and the auxiliary tensioning wheels were deleted.
M48A3: Refit of M48A1s with diesel engines and a new fire control system.

我真不想骂人。
但我觉得用低速圆柱体来和高速长径比10：1以上的高密度弹芯比弹道真的是一件非常白痴的事，两者的初速、密度、横风面积全不在一个等级上，这根本不用大学物理就知道，因为这是常识。
你的常识没学好就别扯什么大学物理了，害臊不害臊？
还有，你别忘记你要拿的是证据，是你有证明英国人用碎甲弹击毁5500米坦克的义务，而不是我有证明没有的义务。
我只需要用常识质疑你这种屁话的可靠性有问题就可以，而你，没拿到实质证据之前就少在那喷。

这个的确你说得没错，还有一个spgr43，这个是榴弹。而Gr39是破甲弹，所以我前面说的是不正确的。
但是，你觉得这种破甲力90mm、破甲力只有口径一倍的破甲弹能推翻我之前说的什么结论？

好吧，我承认美国佬是白痴。
从M48A2C——M48A2E1发展起来的59年的M60都是用机械弹道计算机，62年的M60A1上了模拟弹道计算机，然后像你所说64年在M48A3上又用回已经被取代的机械计算机。这种发展还真够匪夷所思。
况且你这个维基百科不过说了M48A3用了新火控，有没有说它是首先采用弹道计算机的型号？而且fire control system就仅仅包括弹道计算机？
