Minotaur-C
Minotaur-C (Minotaur Commercial), formerly known as Taurus or Taurus XL, was a four stage solid fueled launch vehicle built in the United States by Orbital Sciences (now Northrop Grumman) and launched from SLC-576E at California's Vandenberg Air Force Base. It is based on the air-launched Pegasus rocket from the same manufacturer, utilizing a "zeroth stage" in place of an airplane.
