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 score 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.




Received this from CWO Bob Hinds (ret).

MCPO Dietz: I suspect you've already messaged to CG Veterans/Retirees who served at LORAN Station Enewetak Atoll.  The VA continues in efforts to study potential radiological effects of atomic testing and cleanup of Enewetak Atoll and reminds Veterans to talk to their health care professional and file a claim with the VA if they believe they have health issues related to radiological exposure at Enewetak Atoll.  There appears to be at least nine living former COs, including two retired RADMs, four CAPTs, and three CDRs.
