VANGUARD
 Vanguard was
a three-stage launch vehicle developed for the Navy in 1957. It
had liquid-propellant engines in the first two stages and a solid-propellant
third stage. Vanguard's technical ancestors were the Navy's Viking
and Aerobee sounding rockets.
Much
of the internal hardware was removed when this Vanguard was prepared
for display. It was transferred to the Smithsonian in 1958 after
being exhibited at Andrews Air Force Base in Maryland.
