B-24A/LB-30B Ordered in 1939, the B-24A was the first production model. Due to the need for heavy bombers, the B-24A was ordered before any version of the B-24 flew.
The main improvement over the XB-24 was improved aerodynamics, which led to better performance. Some sent to Great Britain under Lend-Lease as LB-30B.

XB-24N A redesign of the B-24J, made to accommodate a single tail. It also featured an Emerson 128 ball turret in the nose and a stationary tail gunner's position.
While 5,168 B-24Ns were ordered, the end of the war resulted in cancellation of all contracts before production could begin. (Total: one) (U.S. Air Force photo)

XB-24K Developed from the B-24ST, with the B-23 Dragon empennage replaced by the tail of a Douglas C-54 Skymaster.[34]
The improved performance and handling of the B-24ST and XB-24K led to the decision to incorporate a single tail in the PB4Y-2 and B-24N.
