Notes - School Commands:

The CT SUPP school was established at Bainbridge Island, WA in October 1951 and was closed in December 1953.
CT SUPP schools at Bainbridge Island, WA and Imperial Beach, CA were in business at the same time;
but, after Bainbridge Island, WA was closed, only Imperial Beach, CA continued, until it was moved to Pensacola, FL in 1960.

The history of Imperial Beach, CA says: BUPERS established
"U.S. Naval School, Communications Technician, Class A", on October 1, 1949.
On July 1, 1957, NAVCOMMTRACEN was established at Imperial Beach, CA and took over existing schools.
SUPP Scol NAVCOMMTRACEN moved from IB and became NAVCOMMTRACEN Corry Field, Pensacola in 1960;
later, in 1973, CNO changed the name of Corry Field to NTTC Corry Station, Pensacola.
Then on 19 Nov 2002, CNO changed the name of Corry Station to Center for Cryptology, Corry Station, Pensacola
with a PLA of "CENCRYPTOLOGY Corry Station, Pensacola, FL".
Then on 28 June 2005, the name was changed to Center for Information Dominance, Corry Station, Pensacola
with a PLA of "CENINFODOM CORRY STATION PENSACOLA FL".
(No connection with NSGA Pensacola, as it remains today).

NCTC was a BUPERS shore activity at IB, not connected with the CI station there.
NCTC from IB to NCTC Pensacola was a BUPER's activity move and not connected with NSGA Pensacola.
