Theodore Point, Attu Island

I was told this is the old Loran-A station, not the old, old Loran-A station located at Theodore Point.
-Joe Jester

Current Station. Loran-C transmitter buildings (old transmitter building and new transmitter building) in the lower center portion of the picture. The Loran-A transmitters were on the ground floor in the building just off-center of the picture. The new transmitter building wasn't there in 1973/1974 or 1983 when I was assigned to the unit. Loran-A was discontinued before my second tour.

Documents

1948 Letter, file CG-783 awarding the Navy Unit Commendation medal to a member of Construction Detachment 26 [17 MB pdf file]. There in an interesting part of history attached to this letter in the form of a handwritten letter from the recipient of the Navy Unit Commendation. During both of my tours on Attu, I've only known of the Japanese monument marking the Colonel's death (at engineer hill) and the one honoring both American and Japanese at the station. I had never known that Construction Detachment 26 had honored one of their own, at Theodore Point. Bravo Zulu to CD 26.
