Caliber Gun InstallationSelect usageWhat Type of Order?Usage:Early in 1928, Boeing built two new fighter biplanes using bolted aluminum tubing for the fuselage's inside structure, rather than welded steel tubing, typical of earlier models. Later versions had aluminum covering the fuselage rather than fabric or wood. Model 83, designed for the Navy, had a hook-type arrester so that it could land on aircraft carriers. Its production version was designated F4B. The Model 89, built for the Army as the P-12, had a rack that could hold a 500-pound bomb.BI229805 (5587b)Maximum size:2901px × 2280px (~18 MB)9.6in × 7.6in (300dpi)License type:Rights ManagedKeywords:1920s-airplanes-ammunition/weapons systems-biplanes-close-ups-detail views-F4B/P-12 series-F4B-4 (Model 235)-fighters-ground shots-historic production status-interiors-manufacturing-military-photos-Plant I-power-propeller planes-right side views-text-viewed from above-vintage / retro
