The Navaho G-26 was a test version of the operational Navaho G-38 which would have been the fullfillment of the A-9/A-10 concept. Navaho was cancelled due to the success of faster, unstoppable ballistic missiles. But the engines, missile frame manufacturing techniques, inertial and stellar navigation equipment, and telemetry/guidance techniques developed for Navaho established the technical basis for all subsequent US rocket developments. The engine developed for an earlier version of Navaho was used in the Redstone rocket; that developed for the G-26 booster was used in the Atlas A and Atlas B ballistic missiles. The Navaho program was cancelled on 13 July 1957, but the already-built G-26 test missiles were flown to the end of 1958.
