Rocket Engine, Liquid Fuel, Nike-Ajax
- Aerojet General Corp.
- This liquid propellant rocket engine of the Nike-Ajax, built by the Aerojet General Corporatoin, is the U.S.'s first operational surface-to-air missile. The missile used a solid propellant booster and liquid propellant second stage. The liquid sustainer engine produced 2,600 pounds of thrust for about 20 seconds. It used red fuming nitric acid and JP-4, a type of jet fuel, as its propellants. It was a very simple system with no moving parts for ease in operation and high reliability.
- The propellants were forced into the combustion chamber by compressed air. Development of the engine was begun in late 1945 by Aerojet-General and the missile became operational in 1953 and remained in service until 1963. This object was donated to the Smithsonian in 1968 by the Aerojet General Corp.
