"Scamp" operated out of San Diego in the local operating area from January to May 1968. On 11 May, she arrived at Pearl Harbor to conclude an extended training cruise. She returned to San Diego on 19 May and remained there until 15 June, when the submarine shifted to San Francisco to enter Mare Island Naval Shipyard for a three-week restricted availability. She returned to San Diego on 16 July and finished out the year sailing from that port on various exercises and training cruises.
