I-Y, I don't think your comparison is fair, the ab139 is an ultra modern machine, maybe even too new (especially when you see all that "glass" in the cockpit)! While I think a number of us would have preferred the Blackhawk, the 139 is not a bad 2nd best (far better than the 145 and probably better than the S-76).
Remember it comes from two/three companies with great traditions in military helicopters - Bell and AgustaWestland and one would imagine it will turn out to be a very robust machine.
It appears to be able to take 8 fully equipped troops easily, is fast and has adequate range.
My main concern is that it will be used a VIP machine, though hopefully the 135s can be used in that role.
