What is the maximum number of years an E4 is allowed to remain on active duty?

The maximum number of years an E4 is allowed to remain on active duty is 10 years. This is based on the personnel policy guidelines governing enlisted retention. Under these guidelines, the Navy establishes time-in-service limits for each pay grade to manage career progression and ensure an effective and well-structured force.

Once an E4 has served for 10 years, they would typically need to advance in rank, either to E5 or to another higher classification, to continue their service effectively. This policy creates an incentive for enlisted members to seek advancement and pursue additional training, thereby maintaining a motivated and skilled workforce within the Navy. The limits are set to promote career development and prevent stagnation in lower ranks.
