Martin Model 167

XA-22, French "Glenn," British "Maryland" Attack Bomber
Variants/Specifications

Martin worked hard in 1937 to land an Air Corps order that would complement the Navy PBM. One of Martin's proposals caught the attention of Army brass: a dual-purpose "attack bomber" capable of both precision bombardment and low-level "attack" missions over the battlefield. No such category existed in the Air Corps inventory, but specifications for one were drawn up in late 1937.

Although losing the resulting Army competition, Martin received lucrative export orders from prewar France. As a result, 167's served on both sides during World War II.
