The Herk, Huey, P-3, and E-2 are up there too, for t/m/s still in operational service (first flights in 1954, 1956, 1958, and 1960, respectively).
True. Here are a couple of shots posted by the Boneyard the last couple of days that illustrate that:
"Still reigning supreme after years of battlefield victories, AC-130H, Serial No. 69-6569, proudly roared into AMARG today...to rest. Nicknamed "Excalibur," for having the legendary strength of King Arthur's sword, the aircraft is said to be the last AC-130H to retire as well as the last to have served during the Vietnam War.

"Though parking in the shadow of "Excalibur," a victorious AC-130H war horse, this P-3C, BuNo 157329, carries an extraordinary history of its own--26,000 hours and 22,000 landings! Welcome aboard! - May 28, 2015"
