Its a similar case for the Skyhawk. While not specifically being area ruled, the TA-4K has better performance in the transonic arena, due to the large canopy area forward of the wing.
Offsetting this very marginal aerodynamic capability is that in the TA-4K the engine is down-rated, weighs 1000lbs more, carries 1000lbs less gas, the nose is 2.5 feet longer, and has a large lead weight in the tail to balance it out. All in all, the T-birds fly like a pig!
