Seems to have a max take off weight of 19 tons by the look of it. The heli itself weights about 9 of those tons already, which leaves 10 tons of leeway. Those containers, from what I've read around here, can be well above 30 tons each. So that sounds like a no go. Also, they built only 31 of those helis in total according to wikipedia.

Aha, OK, I didn't realize the copter itself was included in the 19 tons.

I also saw someone mentioning 40 feet containers weighing up to max 9000 lb (ca 4 tons), but not sure it is a relevant or applicable number.

And 20k containers. I guess they don't have to offload all of them, but still it is hard to imagine numbers this large.
