Prescribed Sea Tours (PST) for first-term Sailors assigned to FDNF sea duty billets will be up to a maximum of 48 months accompanied by dependents and 48 months unaccompanied. If a Sailor's dependents are not given command sponsorship, a maximum of 24 months unaccompanied orders will be issued.

This change only applies to first-term Sailors on their way to their first sea duty tour in Japan, Guam and Spain, and does not apply to assignments listed in exhibit one of MILPERSMAN 1300-308.

First-term FDNF Sailors currently assigned to a sea duty tour in Japan, Guam, and Spain and Sailors on their second or subsequent FDNF sea duty tour are encouraged to take advantage of the incentives offered to extend their tours, as outlined in NAVADMIN 042/18.

First-term Sailors with orders issued on or after May 1, 2018 will not be eligible for incentives listed in NAVADMIN 042/18, but will have any remaining PST obligation from their first sea duty tour waived. Sailors will only become eligible for the Overseas Tour Extension Incentive Program if they extend after completion of their assigned 48 month tour.
