CTRivers,
MOSID 00116 is NE Tech(A) or Sonar. The academic training you will receve is identical to what the 00118 NE Tech(T) and 00117 NE Tech(C) receive and very similar to what the 00017 NW Tech gets. There will be differences in the application phases of training, obviously.
However, Occupation restructure to W Eng Tech (Weapons ENGineering TECHnician) is tentatively scheduled for Oct 2010, but the date is not firm. It is safe to say that it will happen sooner than later. You will likely find yourself as a generic W ENG Tech until you complete your OJT and a qualification package, after which you will be selected to be one of 5 specialist occupations for training and employment for the next two ranks. Which you are selected for will depend on what is required, experience and training you already may have and your personal preferences. (Yes we do take them into account, but perhaps not with as much weight as you would like). At the PO1 rank everyone will once again be a generic W ENG Tech, so while you may specialize as a technician, once you get to the system/supervisor level, you will deal with all Navel Combat equipments, projects, HR etc.
