Eleven enlisted men departed the station with ten enlisted men reporting for duty. Authorized airman manning remains forty-two with forty-one assigned. The search radar (FPS-93A) was subject to Depot Level Maintenance during this quarter. The entire unit was thoroughly cleaned. All system components were checked and defective components were replaced. The Klystron coolant system was completely overhauled. Also, a new azimuth drive motor and gear reduction assembly was installed in the system. The radar set was finally aligned and made fully operational. The Interrogator Set (UPX-14) was also subject to Depot Level Maintenance during this quarter. The unit was thoroughly cleaned and overhauled. All Video Decoders (GPX-7A) were cleaned and overhauled.
