* to investigate launching techniques for a two-stage missile and separation of the two stages at high velocity,
* to conduct limited investigation of high-speed high-altitude phenomena, and
* to attain velocities and altitudes higher than ever reached. Over-all responsibility for the Bumper program was given to theGeneral Electric Company and were included in theHermes project , and theJet Propulsion Laboratory was assigned responsibility for the theoretical investigations required, the design of the second stage and basic design of the separation system. TheDouglas Aircraft Company was assigned responsibility for fabrication of the second stage and detail design and fabrication of the special V-2 rocket parts required. The program was officially concluded in July 1950 after 8 launches.cite web | title = Bumper Project | work = White Sands History - Fact Sheets and Articles | publisher = US Army | date = | url = http://www.wsmr.army.mil/pao/FactSheets/bump.htm | accessdate = 2007-12-02| archiveurl = http://web.archive.org/web/20080110163113/http://www.wsmr.army.mil/pao/FactSheets/bump.htm | archivedate =2008-01-10 ]Six Bumper launches, as well as other V-2 test launches, were from
White Sands Proving Grounds . In 1949, the Joint Long Range Proving Ground was established atCape Canaveral on the east coast ofFlorida . The July 24, 1950 Bumper 8 launch became the first of hundreds of launches from "the Cape."
