Very graceful plane. What a machine! As an air superiority fighter to counter massive Soviet air attack vs. carrier group, its role will not be replaced. Neither F/A-18 SuperHornets nor the navy version of the F-35 Lightning II will carry that role: nobody today has the air power to attack a carrier group and Ageis cruisers are more adept at countering cruise missles.
The F-111B just wasn't able to combine swept wing design with the ruggedness required for carrier takeoff and landing. But boy, how the Tomcat did excel! Repeatedly, critics said the Tomcat era was past, but advances in avionics and engine technology kept her as the Top Gun for a long time. Some show on The Military Channel recently claimed she was up to 80 man hours of maintenance for every one hour of flight time though. That sounds pretty hyperbolic, but obviously, she was advanced with age. Too rough of a life to keep plugging like a B-52.
When Sen. Sam Nunn was chairman of the Senate Armed Services Committee, he said he'd like to see a modified carrier version of the F-22 to replace the F-14 in the naval air superiority role. Nothing came of it of course. Some people speculate that the USAF "new bomber" may be an F-22 variant, possibly unmanned. I think it was Popular Science that recently had an article speculating that new advances in synthetic fuel were making it possibly to bring back the mythical "Aurora" spy plane in the form of a hypersonic stealth bomber. Interesting!
Farewell, Top Gun Tomcat. We'll miss you.
