Because a Sailor’s Projected Rotation Date (PRD), Prescribed Sea Tours (PST), and the end of their active obligated service (EAOS) dates were all over the map; it made planning for a Sailor’s loss to a command a little precarious – at least until the Sailor would make a decision about re-enlistment, and often times that decision would come late. To try and remedy this problem, the Navy officially began the T+X Accession Program in 2011.
To calculate a Sailor’s enlistment obligation, instead of the hard and fast 4 year (48 month) enlistment, the formula “T+X” would be used. The “T” in the equation is the average length in months of initial training (boot-camp, A School, etc.), the “X” is equal to the calculated length of the first operational tour for the rating enlisted. For those ratings that would benefit from a longer period of enlistment, the obligation is extended from the traditional 48 months to 60 months.
Beginning with those leaving for boot-camp in FY-2018 (October 1, 2017), applicants that enlist into the following six ratings will be required to obligate for a 60 month (5 year) enlistment; the new additional ratings are:
Aviation Structural Mechanic (AM)
Damage Controlman (DC)
Gunner’s Mate (GM)
Hull Technician (HT)
Machinist’s Mate (MM)
The addition of those six Navy jobs raises the total number of T+X Accession ratings to 24. The ratings already part of the program include: ABE, ABF, ABH, AME, AO, BM, CS, CSS, EM, GSE, GSM, LS, LSS, MMS, OS, QM, SH, and STG.
