Dear Mr. Kahn:
 
As requested in your letter of November 10, 1955, the classi-
fication status of Admiral H.R. Stark's memorandum to the
Secretary of the Navy dated November 12, 1940, bearing the 
notation Op-12-CTB and known as "Plan Dog," has been reviewed.
 
The Chief of Naval Operations has declassified the "Plan Dog
Memorandum" and the security classification on the document
in the custody of the Franklin D. Roosevelt Library should be
removed.
 
                         Very truly yours,
 
 
                         L.J. Darter
                         Head, Naval Archives Branch
