Gate guards are, by definition, pretty much gutted. Engines, guns, hydraulics, busses, ejection seats, instruments, armament hardware, all of it is stripped- usually back into the active inventory. It even goes so far as to taking out control surface linkages, etc etc. We have an F/A-18 on display here at Cecil Field that, until recently, Boeing was sneaking over to and opening panels to steal little parts here and there- apparently scavenging can go on for quite awhile.
If anyone wanted to make them airworthy again, you'd have to go back and lay thousands of feet of wires, add all the systems again, engines/seats, etc etc....why do that when we have tons of F-4's and whatnot at AMARC, that can be had for relatively cheap
I had a look inside an A-7 that was guarding a base for many years, the cockpit was nothing more than, well, a pit...the engine compartment was barren, the wing stations were gutted (nothing but the pylon), the radar was out, avionics shelves empty, etc etc...you have to shed alot of weight especially if you plan to put it on a stick.
We have an F-102, F-106, and F-15 on display here at Florida ANG base JAX
...the 102 still has a seat oddly enough, but the others just have their ejection seat rails remaining, and nothing but hollow insides to show for it. There's an F-16 on the ramp right now that's being gutted for the gate as well, if I was allowed to get some photos of the de-mil for you, I would
Next time you get up next to a static (assuming noone is around), try to open a panel...watch out for hornet's nests and such...you'll find pretty much nothing, even the boarding ladder is usually taken off.
"The cockpit, what is it?" "It's the little room in the front of the plane where the pilot sits, but that's not importan
