Vanguard TV3BU, also called Vanguard Test Vehicle three BU, was the second flight of the American Vanguard rocket. An unsuccessful attempt to place an unnamed satellite into orbit, the rocket was launched on February 5, 1958. It was launched from Launch Complex 18A at the Cape Canaveral Air Force Station. Fifty seven seconds after launch, control of the vehicle was lost and it failed to achieve orbit.

The failure was a set back in the space race and let the Soviet Union gain and thus Vanguard was not the first rocket to orbit an unmanned satellite. The first small-lift launch vehicle was the Sputnik rocket, it put into orbit an unmanned orbital carrier rocket designed by Sergey Korolyov in the Soviet Union, derived from the R-7 Semyorka ICBM. On 4 October 1957, the Sputnik rocket was used to perform the world's first satellite launch, placing Sputnik 1 satellite into a low Earth orbit.[1][2][3]

Vanguard TV0, Vanguard Test Vehicle zero was a successful one stage test done on 8 December 1956.
