To go 1/2 way around the world, at 590 mph is 21+ hours.

Cost per hour, according to https://nation.time.com/2013/04/02/costly-flight-hours/ is $23.811

So, the one way cost to get a C-17 full of cargo anywhere in the world is about $500,000

1 Million round trip.

I had the cost wrong, I thought it was per vehicle, it's per launch... $2,000,000. If it could fly back, it's only $4,000,000 per round trip.... just 4 times the cost of a C-17 delivery and return.
