As was the case with other naval air stations retained in operating status following the war, Los Alamitos suffered a period of transitions and changes. Under the command of the Chief of Naval Air Training at NAS Pensacola, its missions were to train reservists and service the fleet. On 1 March 1946, while it provided training, CASU 33 supported Air Group 98, but the devotion of activity could be measured by the fact that, as of 28 February 1946, it had only ninety-seven V-6 personnel on active duty as station keepers, yet until the end of September this group provided proficiency flying for more than 1,500 inactive reserve pilots. Meanwhile, CASU 706 supported Patrol Squadron 908 (VP-908), Escort Carrier Air Groups 779 and 778, and Carrier Air Group 716. On 16 August 1946, the first group of aviation cadets in the Selective Training Program came on board, and after 1 September, the station would be used by the Naval Air Transport Service (NATS). On 13 October, the record-making Truculent Turtle, which had flown nonstop for almost 4,500 miles, paid the station a visit. By the end of 1946, with 243 reserve pilots, 1,375 volunteer reserve pilots, 255 inactive reserve enlisted men, and 368 active duty station keepers, Los Alamitos was one of the busiest Naval Air Reserve Stations. Between January and March 1947, the station became the largest in the entire Naval Reserve air training program.
