With a thrust of twenty-five metric tons (56,000 lb), the V-2 motor was the world's first large, liquid-fuel rocket engine. It powered the first ballistic missile, the German V-2 of World War II. The combustion chamber was the engine's heart and burned the propellants, water alcohol and liquid oxygen, at about 2,700 ºC (4,900 ºF).
NASA Marshall Space Flight Center gave the combustion chamber to the Smithsonian in 1975. These parts were removed during restoration in 2004.
