The Vanguard rocket [1] was intended to be the first launch vehicle the United States would use to place a satellite into orbit. Instead, the Sputnik crisis caused by the surprise launch of Sputnik 1 led the U.S., after the failure of Vanguard TV-3, to quickly orbit the Explorer 1 satellite using a Juno I rocket, making Vanguard 1 the second successful U.S. orbital launch.
Project Vanguard was a program managed by the United States Navy Naval Research Laboratory (NRL), which intended to launch the first artificial satellite into low Earth orbit using a Vanguard rocket [1] as the launch vehicle from Cape Canaveral Missile Annex, Florida.
Vanguard TV-0, also called Vanguard Test Vehicle-Zero, was the first sub-orbital test flight of a Viking rocket as part of the Project Vanguard.. Project Vanguard was a program managed by the United States Naval Research Laboratory (NRL), and designed and built by the Glenn L. Martin Company (now Lockheed-Martin), which intended to launch the first artificial satellite into Earth orbit using a ...
Thus the V-2 program started the Space Race, the V-2 could not orbit, but could reach a height of 88 km (55 mi) on long range trajectory and up to 206 km (128 mi) if launched vertically. [10] [11] [12] Due to problems a delays with Vanguard TV-2 and failure of TV-3, Vanguard was not the first rocket to place into orbit an unmanned satellite.

Vanguard was the designation used for both the launch vehicle and the satellite. The first stage of the three-stage Vanguard Test vehicle was powered by a General Electric X-405 125,000 N (28,000 lb f) thrust liquid rocket engine, propelled by 7200 kg of kerosene and liquid oxygen, with helium pressurant.

Vanguard TV-3 utilized the three-stage Vanguard designed to send the satellite into orbit around the Earth. The fins were removed from the rocket as a way to reduce the drag and instead, the launch motor was mounted in gimbals which allowed it to pivot and direct its thrust for steering. The second and third stages of the rocket were also ...
