Propulsion systemThe Navaho consisted of two parts, a liquid-fueled booster rocket and a cruise missile. The latter carried the warhead and was powered by a ramjet engines. The booster accelerated the cruise missile to nearly Mach 3, at which point the ramjet engines were ignited and the booster was jettisoned.
LegacyAlthough the Navaho program cost $700 million and resulted in less than one hour of flight time, it did significantly influence the development of large liquid-propellant rocket engine technology in the United States. From the Navaho was derived the engines for the Redstone, Thor, Jupiter, Atlas, Titan I, and Saturn I rockets. The Navaho program also led to fuel tank fabrication techniques, inertial and stellar navigation, and other technologies used in later vehicles. The inertial guidance system, for example, employed the first solid-state digital computer ever developed in the United States, and was later used as the guidance system on the first U.S. nuclear-powered submarines.
