The USAF hasn't bought a tail-hook equipped aircraft since the F-111 and the tail-hook on the F-111 was NEVER used for practice -- using it caused structural damge to the USAF version of the aircraft.
Most USAF Bases don't even have arresting cables anymore and not very many still have operational emergency Barrier systems -- the barrier net systems were abandoned and decommisioned before I retired 16 years ago.
The F-111, F-4, F-15 and F-16 all have tailhooks, though the F-22 does not. The tailhooks on Navy jets are more robust and are retractable from the cockpit, whereas the tailhooks on the 15 and 16 are lighterweight hooks, intended only for emergency arrest.
Barriers are prevalent on fighter bases, especially where the 15 and 16 are the predominant aircraft. The Air Force standard AAS is the Esco Bak-12, which looks like a giant disc brake, attached to a diesel engine. The Civil Engineering squadron is responsible for their maintenance, which falls under the 3E0x2 AFSC, the the Electrical Systems shop (3E0x1) frequently helps in their routine maintenance. The SOP calls for a trial of the system at least once annually, if no barrier engagements have occurred. This was usually accomplished
As an aside, I can tell you that the tailhook on an F-15 generates a hell of a lot of FOD when it drops onto the runway, of which I have had to walk afterwards more than a few times. I can personally attest to their presence and use through 1996 on F-4s, F-15s and F-16s, though a Google of BAK-12 bases indicates several bases still have them in use. I know we did away with the net style barrier, but the cables are still very much present.
