Both the SB>1 and the V-280 primary mission is troop transport. As long as soldiers need to get in and out of battle, this mission is not going away.
The mission isn't going away but the question remains if they are not too expensive/complex, too big and too fragile for the mission.
The big plus of the Blackhawk for this mission is that it is extremely rugged, rather nimble and small and not excessively complex and expensive. Almost the opposite of the new vertical lift high speed platforms. The most dangerous phase for the helicopter in combat has historically been the landing/de- boarding phase. And that is the phase where especially the valor is a huuuuge and beautiful target with lots of critical parts widely spread and is also rather limited in its agility and descent rate compared to the nimble Blackhawk. I'm not really convinced that they are not going to cancel the current bid. For certain special missions the new platforms surely offer very interesting possibilities but I have a hard time to figure them as real replacement for the rugged 'bread and butter' combat mule that is the Blackhwak.
