"Jeffers" arrived San Diego 23 December and steamed via the Panama Canal to Norfolk, where she arrived on 9 January 1946. The ship then began her peacetime duty, arriving Charleston on 12 June. She remained there for the rest of 1946 except for a short training cruise to Casco Bay. 1947 was spent on maneuvers in the Caribbean during April and May, followed by exercises on the East Coast of the United States; and 1948 was spent entirely at various East Coast ports on training duty.
