The Bayfields were completed from 1943 to 1945. They were Maritime Commission standard C3-S-A2 passenger and cargo ships converted to troop transports. They had three sets of triple Welin davits on each side and had a nominal 4 LCMs, 18 LCVPs, 3 LCPLs and 2 LCPRs to get the troops and cargo ashore. They also had two 30-ton booms and six 10-ton booms.

The class is sometimes divided by builder, those built by Western Pipe being assigned to the Bayfield class and those built by Ingalls assigned to the Custer class. They differed only in detail, the Custers having a slightly smaller displacement (7845 tons light displacement).

Six units were fitted out as squadron flagships/relief AGCs for division headquarters by extending the superstructure aft of the funnels to add a flag plot and flag bridge and by adding a small deckhouse aft of the superstructure for a CIC, general's cabin, and other staff quarters. The forward set of Weilin davits was removed to compensate the weight. These ships are sometimes listed separately as the Cambria class.
