February 9, 2010 - The U.S. Coast Guard terminated broadcast of the
North American Long Range Navigation-C signal (LORAN-C) on Monday.
The LORAN system began as a radio-based navigation system during World
War II under a secret program to provide the Allied forces with a
reliable and accurate means of navigation at sea in any weather.
Receivers for aircraft were eventually developed and the LORAN system
expanded to all aspects of the military.

LORAN Stations were first established in the LORAN-C system had provided better than 0.25 nautical mile absolute accuracy for suitably equipped users within the published areas and provided navigation, location, and timing services for both civil and military air, land and marine users. It was approved as an en route supplemental air navigation system for both Instrument Flight Rule (IFR) and Visual Flight Rule (VFR) operations.
As a result of technological advancements in the last 20 years, LORAN
become an antiquated system no longer required by the armed forces, the
transportation sector or the nation’s security interests and was used
only by a small percentage of the population. Continued use of limited
resources to operate LORAN-C was no longer a prudent use of taxpayer
funds and is not allowed under the 2010 Department of Homeland Security
Appropriations Act.
The decision to cease transmission of the LORAN-C signal reflects the
president’s pledge to eliminate unnecessary federal programs. In
accordance with the DHS Appropriations Act, the U.S. Coast Guard had
terminated the transmission of all U.S. LORAN-C signals February 8,
2010, effective 2000Z.
