From ol siote on the Net,
in the early 1940s, based on experience gained in building the Model 167/167F twin-engine light bomber (known in Great Britain as the "Maryland" and in the USAAC under the designation XA-22 ), Martin proposed building a development version, powered by significantly more powerful Wright R-3350 radial engines. The aircraft, bearing the factory designation Model 187, retained the general design layout of its predecessor, while the increased engine power was intended to radically improve its performance, flight characteristics, and combat capabilities.
The US Army Air Corps initially showed interest in the project and placed an order for a single prototype, designated XA-23 . However, the contract was soon canceled, even before the design was completed. After this setback, Martin focused on developing another version of the bomber, this time for the British Royal Air Force. This aircraft—designated Model 187B (B for British) and the US military A-30—was commonly known by its British name, "Baltimore .
