Under the terms of the Liberator Production Pool agreement, B-24G was the designation given to the version of the Liberator that was built by North American/Dallas as prime contractor.
The first B-24G rolled off the production line at Dallas in March of 1943. Initially, the B-24G was powered by R-1830-43 engines. The first 25 machines were designated B-24G-NT. They were quite similar to the Consolidated-built B-24D, but had no ventral armament.
In the meantime, the Ford-originated B-24H had been introduced on the production line at Willow Run, with components being delivered to Consolidated/Fort Worth and Douglas/Tulsa for final assembly. Based on information provided by Ford, the nose turret was also introduced on the North American/Dallas production line. However, this did not lead to a new series letter being introduced. Instead, a new production block (B-24G-1-NT) was started to designate the nose-turret-equipped North American-built Liberator. In addition, several other changes introduced by Ford on the B-24H were incorporated into the B-24G-1-DT.
The first B-24G-1-NT was delivered to the USAAF on November 3, 1943. With the nose turret installed, the B-24G was externally identical to the B-24H, and the two types could generally be distinguished only by examining their serial numbers. However, the B-24G-1-NT was initially somewhat heavier than the Ford-built B-24H and subsequently had a poorer performance, but this was soon corrected. Most B-24Gs were assigned to the Mediterranean Theatre with the 15th Air Force.
The B-24G with the nose turret had inward-opening nose landing gear doors only in the first two blocks (G-1 and G-5), and reverted to outward-opening gear doors for the remainder of the production run.
A ball ventral turret was introduced on the B-24G-10-NT production block. Also, R-1830-65 engines were introduced with this variant. The new engines increased the offensive load to 12,800 pounds of bombs.
A total of 430 B-24Gs were built. The last B-24G was delivered in June of 1944. After that, North American/Dallas switched over to the B-24J version, which was by that time the Liberator version being built by all the members of the production pool.
