Proportion of MTOW used as fuel on mil jets?

[Willard Whyte]

E-3D around 43% (although some is unusable). I think Sentinel is around 45%.

I forget the exact fuel figures for a C-130K (64K? Over ten years since I flew 'em...) round about 40%. J must be a bit less though. A-400 around 36% (from Wikipedia).

All for max fuel/MTOW.
