For years, no military program has sparked more fevered speculation from conspiracy theorists than the mysterious High Frequency Active Auroral Research Program, or HAARP. And for years, the Pentagon has been pooh-poohing speculation that the enormous collection of transmitters, radars, and magnetometers in Alaska was some sort of superweapon.
But, it turns out, the conspiracy theorists may not have been entirely off-base, after all.
“HAARP’s main job is to produce radio waves to probe the ionosphere,” an Air Force Research Laboratory officer said in October.
HAARP can actually perform a lot of militarily important functions, all involving the interactions of radio waves with the high atmosphere, magnetosphere and ionosphere.
The document points out that “on the higher frequency end (VHF/UHF) transionospheric propagation is a ubiquitous element of numerous civilian and military communication systems, surveillance and remote sensing systems.” In other words, messing with the ionosphere means you can shut down VHF radio, TV and radar signals at will. As radio hams know, the reflection and refraction effects of the ionosphere make a huge difference to long-range radio reception, and HAARP provides the only means of influencing that.
