性能全方位升级 歼-10CE战斗机是由我国自主研制的全天候、单发单座、多用途战斗机。它的初始型号——歼-10是我国自行开发的第一款中型第三代战斗机， 1998年首飞成功。在此之后经历了一系列的改进改型。 军事评论员傅前哨 告诉中国之声《烽线瞭望》，从歼-10到歼-10C，其外观、机载武器、雷 达系统等都经历了不同程度升级。 傅前哨： 第一款改型叫歼-10B，首先是机头由圆锥形变成了椭圆形截面；第二是座舱盖喷涂了金属膜；第三个改进是增加了红外搜索跟踪系统。 它的进气口由过去的二元可调式进气口变成了蚌式进气口。再加上喷涂了隐身涂料，具备了一定的半隐身性能。可以说是世界上第一款具备半隐 身能力的三代机。要想把一款"三代机"改成"三代半"战斗机是非常困难的，而歼-10C做到了。 在武器系统方面，歼-10、歼-10B它们挂载的中距空空导弹主要是霹雳-12，而近距格斗导弹是霹雳-5E。到了歼-10C他们的空战武器就变成了霹 雳-15中远距空空导弹以及霹雳-10近距格斗导弹。这两款导弹的性能在目前的世界空战武器中都是拔尖的。霹雳-15E的最大射程可超过200公里， 而霹雳-10发射角很大，机动性极强，因此一旦被它瞄上，基本 ...
