At first blush this was the mooted new shape for the NEW F-35C Hook (side profile) design. Change from Hornet Family shape to what appears to me to be an A-4 style design. YMMV. OLD on left with NEW somewhere there.... One must remember that the wire/pendant is raised above the deck by inches [for USN the 'wire support can be a max. of 5.5 inches] but also can be flat when trampled. The complex dance for hook/wire engagement seems to have been solved.
