I got mine beginning of January (and im civilian btw). Because appointment to NAPS is independent from the appointment to USNA, the time can be completely varies by candidates.
About three days ago I got a offer to the NAPS and although it's early to accept the offer I (obviously) did :) hopefully I see more NAPSter in the forum
Btw, I realized none of the documents in the official website are updated to 2016-17 any explanation?
