The High Virgo, also known as Weapons System 199C (WS-199C), was a prototype air-launched ballistic missile (ALBM) jointly developed by Lockheed and the Convair division of General Dynamics during the late 1950s. The missile proved moderately successful and aided in the development of the later GAM-87 Skybolt ALBM. It was also used in early tests of anti-satellite weapons.
