The Navy increased eligibility for the Enlisted Supervisor Retention Pay program (ESRP) May 2, to include supervisors from select ratings in Zone D (16-20 years of service). ESRP is a career-oriented incentive program for experienced senior enlisted Sailors in the Naval Nuclear Propulsion Program who hold the Navy Enlisted Classifications of 3363, 3364, 3365, 3366, 3393, 3394, 3395 and 3396. It replaces the Selective Reenlistment Bonus for those members. When launched in November 2004, ESRP was offered to select personnel with 10 to 16 years of service only. The second phase, effective May 2, further incentivizes highly skilled Sailors with up to 20 years of service. While the Selective Reenlistment Bonus has a policy limit of $60,000 for most ratings in the Navy, the ESRP program offers up to $100,000.
