The FAA has said repeatedly that it plans to use radar to back up GPS. The
reason the FAA is so hot to decommission all the other radio navaids is
that
they are far too expensive and the cost is spread across a very small user
base, whereas the cost of GPS is shared by all segments of society.

Then there is the value all that VHF navigation bandwidth. Perhaps FAA
could use the cash for somehting useful.
