Underneath the warhead was the instrument section, divided into four quadrants devoted to guidance and control, radio, and electrical systems. The nose cap was a fuse for detonating the explosive, 1,650 lbs of amatol, upon impact. The rocket was mainly constructed of thin sheet steel, welded, riveted, and braced around a wooden framework in some sections. The water additive helped cool the motor, which developed maximum operating temperatures of about 4,900 F. Liquid oxygen (lox) served as the oxidizer (the substance providing the oxygen for combustion) while an 75% alcohol/water mixture was the fuel (the substance to be burned). The tanks were removed to lessen the weight supported by the fins. The Museum's artifact has a combustion chamber, but lacks plumbing and many internal components such as the guidance and control systems. The "dimpled" appearance of the rocket's skin, as is very evident in the Museum's specimen, is partly the result of spot welding, which, when cooled, especially around panels in place near ribs or stringers, contracted or shrunk unevenly, although the rocket's skin was also damaged by years of rough handling. Overall, the rocket was shaped for supersonic flight, based on wind tunnel tests. The design of the clipped fins was influenced by the need to ship a military missile through standard European rail tunnels. The V-2 is cylindrical, tapering down towards the base, with four clipped rectangular fins, and tapering down toward the top with an ogival warhead ending in a sharp pointed nose. It was moved to the National Air Museum's storage facility in Suitland, Maryland in 1954, and was restored in 1975-76 for exhibition in the new National Air and Space Museum building. Army Air Forces, and was officially transferred on by what was now the U.S. The Smithsonian Institution's V-2 was acquired in 1946 from the U.S. Josef Goebbels' Propaganda Ministry when its existence was publicly announced in November 1944, two months after it was first deployed as a weapon. Called the A-4 (Aggregat 4) by German Army Ordnance, the rocket was dubbed V-2, or Vergeltungswaffe Zwei ("Vengeance Weapon Two"), by Dr. The V-2 rocket, developed and used by the Germans during World War II, was the world's first large-scale liquid-propellant rocket vehicle, the first modern long-range ballistic missile, and the ancestor of today's large-scale liquid-fuel rockets and launch vehicles. The National Air Museum moved it to its storage facility in Maryland in 1954 and, as the National Air and Space Museum, restored it in 1975-1976 for exhibition in its new Mall building. Air Force officially transferred this V-2 to the Smithsonian on May 1, 1949. At least 10,000 concentration camp workers died in the process of manufacturing it. Launched from mobile platforms, the missile had a maximum range of about 320 km (200 miles) and a one-ton warhead. Called the A-4 (Aggregat 4) by German Army Ordnance, the rocket was dubbed V-2, or Vergeltungswaffe Zwei ("Vengeance Weapon Two"), by the Nazi Propaganda Ministry when its existence was publicly announced in November 1944, two months after first deployment as a weapon. The German V-2 rocket was the world's first large-scale liquid-propellant rocket vehicle, the first long-range ballistic missile, and the ancestor of today's large rockets and launch vehicles.
