The Commodore twin-engined flying boat failed to gain military orders in the form of XPY-1. A total of 14, however, were ordered for commercial use. This was fortuitous, as the Commodore design is recognized as the basis for the important and famous PBY-5 Catalina. The Commodores were ordered by a US-owned South American-based airline called NYRBA which challenged Pan American's regional dominance and was later leveraged to sell its assets to Pan Am (circa 1930). Subsequently Pan Am went on to operate Commodores up to and through World War II, and some machines had short careers with successor operators.
