When did the base where The Naval Academy Preparatory School is located gain over five hundred billets?
Naval Station Newport:  In BRAC 2005 (Base Realignment and Closure), NAVSTA Newport gained over five hundred billets, in addition to receiving, again, the Officer Candidate School (OCS), the Naval Supply Corps School (in 2011), and several other activities, to include a few Army Reserve units.
