Welcome to Loran-History.info

 These pages remember the Coast Guardsmen, who served aboard Loran-A, Loran-C stations, and other Loran billets worldwide. These dedicated Coasties are but a few who provided radio navigation signals to millions of navigators. These pages wouldn't exist except through the efforts of MCPO Bill Dietz, USCG(ret). Bill has spent numerous hours for over a decade collecting the information you find here.

  If you wish to add your information to the database, just fill out the Contact us form. Bill or I will update the list.

  We are looking for pictures and stories.  If you wish to contribute, please Contact Us.

FYI - Site Maintenance underway. 

For the next few months we are conducting an audit of the html pages to ensure compliance with the current standards.  There is extraneous html code on some pages and it needs to be brought up to date.  I am doing each letter of the alphabet as a group before moving on to the next grouping.  If you sent something to Bill that belongs in the portion of the alphabet I'm currently working, it won't appear as timely as others.  Please bear with me during this process.   I hope to make the site more friendly for the mobile users (tablets and smart phones) as well as faster for the wired users.
