Majdi is correct. The budget report I saw showed that it was less to upgrade than to decommission. It still doesn't make sense to rely on only one system with the assumption that it won't break. I think in the future that shutting down these site will be deemed a bad idea.

Not so; Designs for H-field antennas for LORAN and GPS exist, and have been prototyped. eLORAN receivers perform on the order of unassisted GPS, and combined receivers (eLORAN+GPS) beat the accuracy of either. The problem with the -C shutdown is it means they having nearly finished the upgrades, will never run the new system. It's going to cost more to tear it down than finish the modernization.
