The article references a payload of 2.6 tonne for the Blackhawk and 2 tonne for the Puma. I would be curious to see what the delta is at, say 10,000 feet. Sikorsky has never been known for building super high altitude machines but the French seem to do so a bit more. I admit I don't know either machince very well so I stand to be corrected. Maybe the new UH-60M blades make a big difference.
