Westfield-Barnes Regional Airport (RAP) is a joint civil-military airport in Hampden County, Massachusetts, 3 miles North of Westfield and Northwest of Springfield MA. It is now the home of the 104th Fighter Wing and the 131st Fighter Squadron flying F-15C/D's of the Massachusetts ANG.
Located within the base are 6 preserved aircraft and at the time of my visit, one was undergoing a repaint and the rest were displayed in lovely condition which would indicate they are well looked after by the ANG support team. The A-10 at the gate can be seen from outside and possibly the F-84, but you never know a polite request at the gate might get you entry to photograph some lovely aircraft.
