The U.S. military says the HAARP system could:
HAARP as Defense
1. Eliminate electromagnetic pulse effect of atmospheric thermonuclear devices
2. Provide Extremely Low Frequency (ELF) submarine communication using the ocean as antenna
3. Over-the-horizon radar system bouncing off ionosphere
4. Provide a way to wipe out enemy communications over an extremely large area, while keeping the military's own communications systems working
5. Provide a wide area earth penetrating tomography or locate underground bunkers & a tool for geophysical probing to find oil, gas and mineral deposits over a large area
6. Used to detect incoming low-level planes and cruise missiles, making other technologies obsolete
HAARP as Offense
1. HAARP super heaters can create massive weather effects over entire hemispheres - what is done in one place will impact everyone else on the planet. HAARP can be bounced off the earths ionosphere.
2. The U.S. sampled lightning and hurricane manipulation studies in Project Skyfire and Project Stormfury bouncing off the ionosphere to different parts of the globe.
3. Focusing HAARP waves into the planet can cause earthquakes, as well as detect them - part of a project named Prime Argus. As in Japan, the effect is proceeded by an aurora display in the clouds.
4. Behavior modification - Low level E.L.F. waves will cause the human brain to begin to change including its chemistry, modifying behavior. From numbing paralysis to intense agitation at great distances.
5. Human extermination E.L.F. waves, Tesla proved, could damp out the human electro-magnetic field from a great distance, causing brain and heart to stop functioning.
6. Holes cut through the ozone allow direct suns radiation to the oceans floor and destroy animal location senses, (as in whales and bees and migrating birds).
