“Current plans, if not modified, could lead to an overreliance on GPS-based systems for critical transportation functions.”1 These words ring as true today as they did in 1997, when they were written in the report of the President’s Commission on Critical Infrastructure Protection. That plan—to discontinue the Coast Guard’s LORAN-C radionavigation system, an alternative to GPS—was enacted in 2010.2

Since then, great power competition has exacerbated the vulnerability of the U.S. GPS infrastructure, and there has been a lack of urgency among government agencies charged with developing a new, enhanced LORAN (eLORAN) system. The Coast Guard, however, is uniquely positioned to ensure the U.S. military will be equipped to deal with the consequences a great power conflict may inflict on its GPS infrastructure. It is time for the Coast Guard to take the lead on eLORAN.
