Orbital Sciences Minotaur
The use of redundant LGM-30F Minuteman II missiles as space launch vehicles has been the subject of a number of proposals. Only one of these proposals resulted into an actual launch vehicle when Orbital Sciences combined the modified first and second stages of the Minuteman II missile with the Pegasus upper stages and avionics. Named the Minotaur, it gave the combination a launch capability of 640 kg into a low-Earth orbit.
