Question is not, could see or not. Question is how far will be seen military plane, BEFORE it will fire weapons. Why? - This is simple, because military need to detect enemy plane significantly earlier, than it will reach fire distance. For different weapons fire distance differ, but I could write approx magnitudes: Canon : effective on 300-1000m, could reach about 3000-4000; Free fall bombs : hundreds meters from point of drop; glide bomb: kilometers from point of drop (The AGM-154 JSOW has a range of 12 nmi (22 km) for a low altitude launch, or 70 nmi (130 km) for a high altitude launch.); guided rocket: most known (and used) have ranges, few tens kilometers, but exists relatively small with range 120km, and big with ranges 1000km or more. And from f-117, main weapon of stealth are rockets, or glide bombs, and detection range for them in best for target case, about few kilometers. So in most cases, if you are target, you will receive present, even don't knowing, who have sent it.
