Can be many reasons for them. May be necessary to increase ground clearance,
that big turbine may need bigger 4 blade. Or it could be noise reduction. Who
knows. The latest C130 has even more blades, of the scimitar shape.

Fuel burn related to all those blades on the prop? I am no engineer but would
seem efficiency would be down with each blade turning in the wake of the
previous.
Probably a myriad of other variables that would not even know to think about
but the number of blades strikes the lay person as unusual.
