Arresting Hook F-4 Phantom

Arresting Hook F-4 Phantom

USS Midway Aircraft Carrier Museum

The tailhook is a strong metal bar, with its free end flattened out, thickened somewhat, and fashioned into a claw-like hook.
The pilot is capable of raising this bar to its inflight position or lowering it ("Hook Down") for landing.
Aircraft land on the flight deck of an aircraft carrier on a short "landing area", towards the aft end of the ship.
A number (usually four) of very greasy and very strong thick flexible cables called arrestor cables, "arresting wires" or "cross deck pendandts" are stretched across the landing area.
When an aircraft lands properly, the tailhook should catch one of the cables and the cable will transfer the energy of the aircraft, through a "purchase cable," to the belowdecks arresting gear engines, stopping the aircraft.
Both the hook and cables have to be very strong: aircraft land on carriers at full throttle, so as to have enough power to go around if the hook misses all the cables.

I spent 10 years working on the Phantom and had to replace the "hook point" on the end of the shank several times. They would wear down thin and when too worn would have to be changed.. it was a double wedge setup, one sliding in from both sides, one having a bolt shank molded on, and a nut with washers and cotterkey to lock in place. One thing of interest, the hook shank was hollow. The hook was dropped by gravity and had a dampner on the actuator to keep it pressed down on the ground. When deployed, it would drop about a foot and then the dampner would lower it slowly. If you look at the top left of the picture, you see the hook point and safety pin that holds it retracted while parked. if the hook was dropped onto the cable holding the pin, you had to have a couple of people push it back up into the locked position. Procedure was, after resetting the hook, was to remove the pin and, standing well clear, drop the hook. The hook would come down with enough force to crack the concrete ramp if it was weak. This was shown to most new mechanics and pilots, which lead to great respect for this piece of metal. Never walk under the hook.....or thru an engine prop arc!....lol

Very cool POV for the 'hook' overhanging the carrier deck.
