The Arthur Middletons were completed in 1942-1945 as attack transport squadron flagships based on Maritime Commission standard C3-P&C hulls. As such, they sacrificed some carrying capacity in return for greater communications facilities. The ships carried 22 LCVP and 2 - 4 LCM(3) landing craft.

The lead ship of the class was originally launched as African Comet on 28 June 1941 and acquired by the Navy on 6 January 1942, being renamed Arthur Middleton the next day. The ship participated in Operation BOBCAT before being taken in hand for conversion to an attack transport. The other two ships had similar histories, but served in the European war before being transferred to the Pacific.
