Its profile looks Longbow-ish, and I imagine the stripes on the rotor are for testing purposes; however, I'll leave it to someone who knows better to make the final call.
Not an Apache. The horizontal tailplanes on an Apache are much further aft than the ones on the helo in the photo. Could be a UH-60 as the aircraft is located just north of both McGuire AFB and Fort Dix Army base.
