The US needed to move a large army from America to France. It needed a lot of troopships. Requisitioned civilian liners and captured German ships that had been interned when the US was neutral provided the bulk of these vessels. Work on designs began soon after the initial work on mine layers,There were two separate groups of designs; one for transatlantic ships and another for cross channel movement. With one exception, these ships were not reported in ONI aide for information reports. They are represented only in bl patterns.ack and white photographs. Some of the ships carried more than one pattern during their service. They started in Mackay or Brush designs while the Navy camouflage section was being organized, and later received USN patterns.
