The P-51H was designed using the latest ideas of the US Army Air Force and North American Aviation for what would be the best long range escort fighter The P-51H looked similar to it's predecessors, except for a new wing planform, and sleeker fuselage, and taller vertical tail.
NACA used the P-51H to test different airfoil shapes mounted above the wings.
