A recent issue of popular mechanics mentioned the LORAN system. Apparently the Coast Guard is going to maintain the system as a backup to the GPS.

The AIM actually talks about the Coast Guard's involvement with LORAN. The thing is that Obama wants to get rid of LORAN. Which means the Coast Guard will probably get rid of it.
I seriously think the FAA shouldn' use only GPS for navigation as the network may go down for a day and leave tons of aircraft without navigaitnoal instruments other than a sectional.
The USCG has originally maintained LORAN, as it began as a nav system for ships. Anyone in the southwest can see the USCG LORAN station located in Searchlight, Nevada on US 95 south of Boulder City.
Our Pegasus boxes have an ANP indication. You can also set an RNP value so that if the ANP goes pear shaped, it will alert you.
Pretty handy when you're 'flying the bowl' in Quito.
Not that I've, uhh, ever done it, but did it a nauseating amount of times in recurrent.
All you need is a sweep hand clock, a map with terrain relief, and good amount of SA......and you're good, whether you're in the bowl of Ecuador, or the Plain of Jars, Laos.
Yeah, but yanking a cranking an A-10 "nap of the earth" is a wee bit different than a fully-loaded Boeing 767-332! Can't necessarily climb over the crest of a hill, roll inverted to keep a positive load and dive back into the valley!
Well, you probably could but the skipper may not like it.

Doug, I know you'd take an LOA in a heartbeat in order to go fly a C-123 dropping "hard rice" to places in South America and Southeast Asia.......

The technology is there, but it will be a long while before they get eliminated for all the usual reasons.
When we start seeing GPS as a 91.205 requirement for IFR, then "DOOOOOOOOOOOOOOOOOOOOOOOM" will be on the horizon for the ILS. Still some years off.

There was a new one installed at PUJ (new airport, I've flown the approach, works just great) just this past November, and FFC added a glideslope to their existing localizer around the same time. A few other airports in Georiga also have plans in the works to add an ILS or add a glide slope to existing localizer approaches.
LAAS is supposed to permit LPV approaches down to Cat II minimums if I have read correctly.
I have a feeling that the number of stand alone (ie., not used as a compass locator for a localizer or ILS approach) NDBs will probably rapidly decrease over the next few years. Just from looking at some local NOTAMs, it seems like when one like that goes OTS, and the airport has other approaches available, it tends to stay that way and is ultimately decomissioned.
