The intent of those vessels is to provide the basic supply support required by a naval task group, to be able to provide transport for whatever might need to be transported using a cargo deck, and to provide support to forces ashore from a secure location at sea.
The amount of room in one of those ships for transport is useful for a tactical deployment of an army unit, but is relatively modest compared to what would be in a cargo ship—one of the large container ships you'd see in Halifax or Vancouver or Montreal. So it might have a role to play in the region, but I doubt we would use a ship like that today. We could use a ship like it today to transport goods to the region, for overland transport then into Afghanistan, but it would not be the principal use of the ship.
