What is a HARP machine?

HAARP is a research station for the United States military, located in Gakona, Alaska; the acronym stands for High-frequency Active Auroral Research Program. Currently, HAARP is a 180-antenna array constructed by BAE Systems, which is a British multi-global aerospace, security and defense corporation.

There has been speculation that the purpose of the HAARP program is to build an electromagnetic weapon, modify the weather, influence global communications or cause earthquakes. HAARP officials have denied all of these claims, and the mission statement on the HAARP website is to study the properties and behavior of the ionosphere and use the discoveries to improve civilian and defense surveillance systems.
