I could swear I saw something that said "50 ns", though I can
no longer find it and that sounds like science fiction. I note,
though, that the Federal Register publication for the project,
here:

indicates they aren't just looking at Loran by itself. The
MF dGPS bands and 500 kHz are also included in whatever they
are doing.
