The dungarees were worn through the period, until about 1972-74. The wearout dates and the issuance do not always combine to form a neat start and end date, so overlapping dates are often more the rule than the exception. At this time the Navy was trying to transition to the new utility uniforms which replaced the dungarees for a few years before they were redesigned and reintroduced. Most of the new utility uniforms started issue to the new recruits, with other commands getting them as they became available.
