Just my opinion, but I think this is a combination of factors that are snowballing, and the applicant pool is where most of the backups get fixed. Most likely, it's the issues the Navy is having regarding the timeline of training pipelines, e.g., maintenance issues with the T-45C causing backups in intermediate/advanced, which causes backups for those class-up pools, which backs up primary (which is already backed up as is), which backs up NIFE. Now you have a surplus of SNA's sitting around in Pensacola with no way to expedite them through the pipeline. This trickles down to the boards, where they're told that they literally can't take any new SNA's for an indefinite amount of time. Next thing you know, the last 4 SNA boards have been cancelled. Combine that with the current job market, causing an increased number of applicants, and you've got a perfect storm. I've read in other threads that this is nothing new, and it will sort out eventually, but it might suck for a while until then. I've also heard about NIFE increasing the passing standards to try and weed out fresh Ensigns.
