Although in a completely different context, that isn't really such a good name.
In short, they're making a satellite that houses telephone pole-long tungsten rods, and is able to drop them down to earth whenever someone wants to see what it looks like when a telephone pole is dropped from orbit. The tungsten shell, is propelled only by gravity itself, with some minor stuffies on it for slight course adjustment. The shell would basically accelerate to several thousand kilometres per second, hitting the ground like when Superman couldn't fix his radio and slammed his desk in rage. Because it really matters that you hit the cat instead of allowing the resulting shockwave to decimate everything in about a kilometer from the point of impact.
Yes, because the Orbital Strike System(I'm just making that up, because I think it's better than Rods from God) effectively delivers a nuclear blast, only with zero radiation issues. Unless you aimed it at a nuke. Which, ironically, is probably what this thing is being designed for: To use against countries that are in violation of those nuclear treaty stuffs.
They're man-made meteors, and they can be launched at anything, from anywhere. If you plan on updating your bomb shelter, make sure that you have some sort of missile deflection system. I really doubt that even the thickest shelters can withstand a frickin' meteor strike. A meteor that happens to be made of really hard metal.
By the looks of it, the real life Orbital Strike is going to be a whole lot more impressive than GDI's support power. It's going to become the ion cannon of our age. I can already imagine the time when there will be an entire system of these things floating around, ready to smite all who oppose... The people who own the things.
I'm totally going to buy one just so that I can make a Zeeky Boogy Doog joke.
