NW040 Redstone tactical missile
In July 1951, Von Braun and his team began to build a large
guided missile - Redstone. To power this missile, North American
Aviation scaled up a V-2 engine, that burned a liquid
oxygen-alcohol fuel. During the powered portion of flight,
control of the missile came from carbon vanes located in the
engine exhaust and after that from air rudders on the tip of each
fin. It was determined that the range and accuracy could be
increased if the warhead separated from the booster after engine
burnout. The warhead section had four air vanes to control the
final trajectory to target after separation. The warhead was
W-39 thermonuclear device with an explosive force of 2.5
megatons. The Redstone was considered an intermediate-range
ballistic missile (IRBM) and was designed to be launched in the
field and became operational in 1958. Redstones were deployed in
Europe until 1964 when the Army replaced the Redstone with the
smaller and more mobile Pershing missile system.
