The T+X Accession Program Adds Six New Jobs

Six Ratings Now Require More Time

Updated: May 24, 2017

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)
Engineman (EM)
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.

    Google “navy recruiter locator”, and on the locator page, enter your zip code. It will provide the phone number and address for both your closest enlisted and officer recruiters.
