On the contrary my friend. You know that I'm one of the last people to suffer from ASS.
I have no problem with the idea that Iran can bring down American UAVs, I just have a problem with them bringing down this PARTICULAR UAV. To bring
down a UAV, you have to know pretty much exactly where it is. They could know when it took off, just by watching Kandahar, but how do they know where
it's going? And how do they find it? We know that the RQ-170 flies about the same height as the U-2, which puts it in the 75-80,000 foot range.
That means that very few radars are going to get a skin paint off it to begin with. The RQ-170, being a flying wing, is naturally going to have a
very low RCS, before you add the other features, such as RAM. Any ground based radar that does get a signal back, is probably going to filter it out,
because it's such low energy the computer will think it's noise.
We already know that the E-3, which has an outstanding radar (which on occasion detected F-117s flying "lights out") only knew where the Sentinel
was, when U-2 pilots complained about not getting traffic warnings about aircraft flying at their altitude. The AWACS response was usually to the
effect of "There's nothing there." An airborne radar has a much better chance of picking up stealth, as the radar signal doesn't have as far to
travel, so the computer is less likely to filter it, as it will have more energy when it hits the antenna on the way back. So this tells us that
it's an extremely stealthy platform.
So how did the Iranians know where it was? You would need a lot of power to jam the signal to the aircraft, because of the altitude it flies at. You
couldn't just broadcast in the blind, and hope to jam it, so you would have to know pretty close to where exactly it was, so how did they track it?
Not just because the US can't, but because the odds are most definitely against a ground station being able to track it, due to power, range, and
other factors involved. So how did they find out exactly where it was to jam the signal and bring it down? It almost definitely wasn't radar, it
certainly wasn't IR or audible tracking methods, and the odds of it being optical are so remote as to be laughable. You would have to look at
exactly the right place, at exactly the right time to see it to start with. I have trouble finding aircraft that I can hear, that are at a much lower
altitude, let alone something that I'm guessing is in the area, and isn't leaving any kind of visual clue as to where it is.
The reason that I believe it either crashed on its own, or was deliberately brought down, is just because the odds are so far against it being hacked,
without some kind of inside help (by anyone, not just Iran) that I just don't see it. I could be wrong, lord knows I have been in the past, but
there's just too much that doesn't make sense here for me to say the Iranians brought it down.
