See my previous posting.

HAARP was orginally conceived to generate ELF signals - if I recall 
correctly for communications with
submarines while submerged.

Prior to HAARP there was a project to install an ELF antenna across the 
state of Wisconsin (project Sangine) - but public outcry put pay to that.  
HAARP and the other Ionospheric heaters work by acting upon the polar 
electrojet and it only requires a relatively small amount of power (but in 
the MW range) to effectively modulate the electrojet.

Compared to the cost of an aircraft carrier or aircraft - HAARP is cheap! 
Probably paid for out of petty cash.
