It seems like the combination of C-130's airfoil, A-400M's T tail and winglet on passenger planes seems to emphasize the field airport.What is difficult to confirm now is whether AEP-600(WJ-10) has been installed. I guess not. It will be at least a few years before it is replaced.
Apologies for (again!) being the annoying dickhead but technically airfoil refers to the cross-section shape of a wing, I presume you’re referring to the wing planar shape being similar to that of the A-130 (both having essentially zero sweep)?

Yes, the latter, after all, it is impossible to judge the cross-sectional shape of the wing by fuzzy video.

True, true. Plus the A130 airframe is ancient as far as transport aircraft goes so I’d be surprised if the design team didn’t use more modern tech and design features on this

Although the C-130 is indeed older, it is more likely to be a design choice. It does not pursue high speed so much, but requires short takeoff and landing capability.

Agreed, although I was mainly referring to the advancements made in aerodynamics and structural design, as well as optimization processes that wasn’t available when the C130 was designed.

For example afiak the C130 uses standard NACA airfoils, whereas most modern designs would take a reference airfoil and optimize the shape to better suit its design point. These types of design optimization just wasn’t possible (or at least would be much much more labor and time intensive) during the 1950s without the level of computation power we have now
