History of the LORAN System

This is a shortened version of the 1947 "LORAN for Ocean Navigation" filmstrip produced by the Coast Guard as a sales pitch to commercial shipping lines to adopt LORAN (as a both a navigational aid and to assist in distress situations). Updated with a new narration track in place of the distorted period track, the film provides a brief wartime history of LORAN, and its significance to the American war effort.
