My thought seeing the photo was C-130. It is the same basic model as the "Fat Albert" the Navy Blue Angels fly for air shows. The take off / landing distances needed are impressively short considering the size of the plan and their cargo load capacity.
When I was stationed at NAS ADAK our station plane was and old C-130 that USED to be a FAT ALBERT.
I rode it home to Anchorage one weekend,,,,, they placed forward facing non-reclining seats in it.
I agree with Josh, worse flight I ever did have.
I rode a C 141 from Adak to Anchorage once....
Web troop seating along the side and half pallets in place in the middle.
COMFY AS HECK! Best flight ever!
