Boeing 100/P-12/F4B in flight. In 1928, Boeing developed the first in a family of fighters that would be one of their most successful designs between wars. The Model 83 was a biplane fighter that flew at nearly 170 mph (272 km/h) -- considered hod-rod performance for its day. Refined and improved versions became the Army P-12, the Navy F4B, and the Model 100 series. Nearly 600 examples of Boeing's "Fighter Family" were built.
