Carl, let's be careful here. LORAN was primarily deployed in North
America (I believe there was also some coverage in the Pacific due to
US territories there and Japan also operated a chain). Loran is being
brought back in the US. I don't know about Canada and I'm pretty sure
it's not being resurrected in the Pacific. So while it's great (I did
a lot of precision electronic navigation using Loran way before GPS)
Loran certainly doesn't provide the worldwide coverage provided by GPS.

In pre-GPS coastal navigation from my era we had Loran-C, radar, RDF,
pelorus, gyro-compass, sextant, and the depth sounder.
Well, most of those tools are obviously still available to the mariner who chooses to use them. RDF is gone, but LORAN is making a comeback. After several years of on-again, off-again funding, debate and deliberation, plans are now going forward to complete an upgrade to LORAN that will allow the system to serve as both a backup and an enhancement to GPS.
