I suspect the the Mike Device (thermonuclear device
for Operation Ivy) was being worked on at Los Alamos and possibly ready for movement to the Naval Supply Center (NSC) in Oakland, California.
On 18 August 1952, the USS Curtiss departed from San Diego and sailed to the Naval Supply Center (NSC) Oakland, California, arriving on 19 August 1952. The USS Curtiss then onloaded special equipment and classified material (note: Mike Device included). Loading was completed on 27 August and USS Curtiss moved to nearby Port Chicago for loading of more material. USS Curtiss departed Port Chicago for Eniwetok Atoll on 29 August 1952.
