"Enterprise" was one of fourteen ships to be fitted with the RCA CXAM-1 RADAR. She was first based in San Diego (where she was used in the movie "Dive Bomber") and then at Pearl Harbor after President Roosevelt ordered the Fleet to be based far forward. "Enterprise" and the aircraft squads she carries trained a lot and moved aircraft among the island bases of the Pacific. "Enterprise" left Pearl Harbor on 28 November 1941. "Enterprise" was completing a transport mission, returning to Hawaii after moving Marine Fighter Squadron 211 (VMF-211) to Wake Island on 7 December 1941. This was when the Japanese attacked Pearl Harbor.
