I remember being interested in GWEN when it was announced, and later 
found one of the sites was along US-30 in eastern Iowa which I travel 
often.   I drove up to the gate and took a look but not much to see but 
equipment buildings and the tower.   Then a few years ago I couldn't 
find it, and recent Google Maps imagery confirmed that it was gone.  The 
location at US-30 and Indian Rd. just east of Mechanicsville IA has been 
returned to farmland.

Here are side-by-side satellite images from Google Earth that confirm 
this happened between June 2014 and March 2016:

I've read that a partial GWEN network call the Thin Line Connectivity 
Capability (TLCC) was completed, which consisted of 8 input/output 
stations, 30 receive-only stations, and 54 relay nodes.  It provided "a 
limited level of HEMP-protected communications to strategic forces and 
the National Commany Authority".

Evidently no longer needed...(?)
