HAARP, also called the High Frequency Active Auroral Research Program, is primarily funded by the United States government. The project is jointly funded by public and private interests.
The U.S. Navy, U.S. Air Force, Defense Advanced Research Projects Agency and the University of Alaska are the largest contributors of the projects funding. HAARP is a United States military site with scientific research applications; as such, it is owned by the U.S. government. The site is operated by third-party contractors and protected by the U.S. military. As provided by the U.S. Constitution, Congress controls the amount of funding allocated to the military and its related projects.
