Bell D-255 Iroquois Warrior / D-262
In June 1962, Bell invited US Army officials to Fort Worth to see the mock-up of a combat helicopter. Known as the Design D-255 "Iroquois Warrior" and wearing false s/n 62-00255 (HU-1F), the relatively small helicopter retained several features of the UH-1 and had a low silhouette, narrow profile and a small cross-section forward fuselage. This streamlined fuselage with retractable skids had been designed for maximum speed, armament payload and crew efficiency. It featured a stepped cockpit configuration with the gunner placed just in front and below the pilot. Armament included a ball-turret in the nose, a streamlined gun compartment under the fuselage and various external loads. Although innovative, the D-255 retained the powerplant as well as the basic transmission and rotor system of the UH-1C in order to reduce maintenance and development time as well as to cut costs.
