Naval Aircraft Factory N-1

The Naval Aircraft Factory N-1, also called the Davis Gun Carrier, was a floatplane built in 1918 by the Naval Aircraft Factory, the United States Navy's own aircraft production works in Philadelphia. It was a biplane with a single Liberty L-12 engine driving a pusher propeller, and it was the first aircraft both designed and built by the factory. Its purpose was to carry the Davis gun, the first recoilless gun, as a maritime patrol aircraft. The first prototype crashed on its maiden flight because of poorly designed floats, but it was rebuilt. Performance did not meet expectations, and after two of the four prototypes were damaged in serious crashes the Navy canceled the program.
