If you are a young officer who has decided to join the surface warfare community, you will arrive on your ship directly from your commissioning source. Unlike years past, there will be no intervening school experience designed to certify that you arrive with an assured level of ship knowledge. Rather, it will be presumed that you learned and retained a broad range of surface warfare topics while at your commissioning source.
On the face of things, this makes sense. As an ROTC student or a Naval Academy graduate, for example, it is a given that you did, to a lesser or greater extent, learn about those things. Of course, some of what you did learn was taught as many as four years ago. Also, you may have been so far removed from graduation that you did not pay close attention, or perhaps you never planned to be a surface warfare officer (SWO) in the first place. The point is that while you may have had the classes, there is at least a chance that the content did not fully stick with you the first time.
