LORAN-C Termination Information

LORAN-C was originally developed to provide radionavigation service for U.S. coastal waters & was later expanded to include complete coverage of the continental U.S. as well as most of Alaska.

LORAN-C has, as a result of technological advancements in the last 20 years, became an antiquated system no longer required by the armed forces, the transportation sector or the nation’s security interests and is used only by a small percentage of the population. The Coast Guard understands that LORAN-C is still used by a small segment of the public and that those users will have to shift to GPS or other systems; however, continued use of limited resources to operate LORAN-C is no longer prudent use of taxpayer funds and is not allowed under the 2010 DHS Appropriation Act.

The Coast Guard published a Federal Register notice on Jan. 7, 2010, regarding its intention to terminate transmission of the LORAN-C signal Feb. 8, 2010.

The Coast Guard strongly urges mariners currently using LORAN-C for navigation to shift to a GPS navigation system and become familiar with its operation as soon as possible. Mariners will not be able to rely upon LORAN-C for navigation as of Feb. 8, 2010.
