During World War I, which country produced 15,000 airplanes?

The United States significantly ramped up its aircraft production during World War I, ultimately producing around 15,000 airplanes, which played a critical role in the war effort. This increase in production was a response to the urgent need for air power to support ground and naval forces. The commitment to developing and manufacturing aircraft was enabled by substantial governmental support and investment, as well as the establishment of numerous factories, which allowed American industry to meet the military's demands.

In contrast, other countries also produced aircraft, but their overall numbers did not reach the levels achieved by the United States during this period. For example, while Germany and France also had strong aviation sectors and produced thousands of aircraft, the scale and efficiency of American production efforts were notably higher, particularly in the latter years of the war. The United Kingdom had a strong aviation industry but still fell short of matching the United States' output in terms of total airplanes produced by the end of World War I. Therefore, the United States stands out as the country that produced around 15,000 airplanes during the war.
