The Boeing P-12 is a biplane fighter aircraft that was used by the United States Navy in the 1930s. It was designed by Boeing and first flew in 1932. The P-12 featured a fabric-covered metal structure and was powered by a radial engine, which gave it a maximum speed of around 200 miles per hour. This aircraft was notable for its agility and performance, making it a popular choice for naval aviation during its time. The P-12 served as a primary fighter until it was gradually replaced by more advanced aircraft, paving the way for the development of future military planes.
