Naval Air Warfare Centers are research organizations within Naval Air Systems Command. The Centers are grouped into different divisions, each with a different history and location. In the 1990’s, it was closed from it’s original base in Pennsylvania and combined with the other test divisions at NAS Patuxent River, MD. This is the triangular version of their squadron patch that shows (what looks like to me) an F-16 Fighting Falcon and this patch does NOT have velcro attached.
