LEX-Leading Edge eXtension...the hood that goes from forward of the cockpit on the hornet back to the wings. it increases the AoA an aircraft can experience without stalling.

Also, didn't the early cats have engine problems, especially at low speeds and high alphas?

I think you're right about the high-alpha improvement on the Super Hornet. Saw both it and a regular Hornet do high-alpha passes at the NAS Pensacola airshow and the difference was notable. I don't know how high above their respective stall speeds each was going but my IFS semi-trained eyeball noticed a big difference, maybe 5-10 degrees more AOA and noticeably slower. Couldn't believe the Super Hornet wasn't falling out of the sky.

The Pratt & Whitney TF30 engine used in F-14A was transplanted from the F-111B since nothing better was available... and short sightedness by the navy resulted in it not being replaced. The TF30 engine was prone to compressor stalls (and turbine blades disintegrating as a result) at high AOA, engaging/disengaging afterburner (engaging burner apparently caused sort of a shockwave to be sent out of both ends of the engine... the one going forward direction causing a compressor stall), or extreme forward/side slip maneuvers (as occurred when Kara Hultgreen cut off airflow to her portside engine in her fatal trap attempt aboard Lincoln).

The reason Grumman went with the TF30 was because of a previous contract obligation with P & W.

contracts are contracts but yeah it would have been nice to see the f110 put in then maybe some more advances could hav been made sooner
