On board during the first quarter of 1948 were a light carrier aircraft group (CLG); two carrier air groups; two escort carrier air groups; two patrol plane squadrons; three transport squadrons; four fleet aircraft service squadrons; two Marine fighting squadrons and a Marine ground control interceptor unit; two volunteer units, one at Litchfield, one on the station proper; a NATS Unit; GCA; and an all-weather station. Until it was decided that there were not enough personnel to continue associated volunteer units at Bakersfield Municipal Airport and Santa Barbara, Los Alamitos assumed administrative responsibilities for them. At the station full operations were carried on for five days a week from 0730 to 1630. Saturday night was reserved for night flying. Operations were limited on Mondays and Thursdays; weekends were madhouses as the "weekend warriors" came on board.
