F4B
The Boeing F4B was a pioneering single‑engine fighter developed in the early 1930s as Boeing’s answer to the rapidly evolving demand for fast, maneuverable combat aircraft. First flown in 1932, the prototype emerged from Boeing’s Seattle Division under the direction of chief designer Edward “Ted” Edmonds, who combined the sleek low‑wing monoplane layout with a powerful radial engine. Powered by the 730 hp Pratt & Whitney R‑1830 Twin Wasp, the F4B could reach 280 km h⁻¹ (175 mph) and climb to 5,000 m in under ten minutes, giving it a distinct advantage over contemporary biplanes. Its all‑metal stressed‑skin construction, retractable oleo‑type landing gear, and enclosed cockpit set new standards for durability and pilot comfort. Armament consisted of two synchronized .30‑caliber machine guns, with provisions for external bomb racks added in later variants.
Although only 96 units were produced before the program was superseded by the more advanced Boeing P‑26 “Peashooter,” the F4B’s innovations influenced the design philosophy of subsequent U.S. fighters. It demonstrated the feasibility of metal monoplane fighters, accelerated the transition away from fabric‑covered biplanes, and cemented Boeing’s reputation as a leading military aircraft manufacturer in the interwar period.
