The unit was a World War II B-24 Liberator replacement training unit (RTU). Its graduates were then assigned to combat units in overseas theaters worldwide as replacement personnel. Originally a Second Air Force unit, it was reassigned to First Air Force when Second AF began B-29 Superfortress training. Inactivated in 1944 when the need for B-24 aircrews was diminished.
