If you really want perked transports how about:
C54 (DC4), 275 mph, 21,000 lbs (say 3 airfield supply boxes)
C69 (Lockheed Constellation), 340 mph, 50,000? lbs (say 6 airfield supply boxes)
vs
C47 (DC3), 220 mph, 6,000 lbs (one airfield supply box)
The C69
was used in WWII in very small numbers at the very end of the war. But it looks so cool
