The B-24 had model variants from the A model through the M model. The biggest changes came with the B-24C, which added top and tail turrets, and with the B-24G, which saw the addition of a power turret to replace the handheld twin .50 caliber machine guns in the nose. The J model was the variant produced in the largest quantity. Of the staggering 18,188 Liberators built, 6,678 were Js.
While the Liberator didn't have the same ability as the Flying Fortress to absorb enemy fire, it did what it was designed to do - it took the war to the Axis Powers and it flew faster, farther and with a larger bomb load than the Flying Fortress.
