Nope. Wings were fixed. It did, however, have large fixed ventral fins near the wingtip that served much the same function as the dropped wingtips of the B-70, without the added complexity of the hinges. Might have even weighed less.As far as I know the F-108 would behave like a sort of scaled down version of the B-70, so the tips should bend down like the Valkyrie's ones....
