The Boeing F2B was a biplane fighter aircraft developed in the 1920s for the United States Navy. It was designed to replace the older F4B series and featured a robust airframe and powerful engine, allowing for improved performance in aerial combat. Equipped with a combination of machine guns and a sturdy structure, the F2B was used primarily during the interwar period. Its versatility made it suitable for various roles, including reconnaissance and ground attack, before being phased out in favor of more advanced aircraft as technology progressed.
