Streak or STP-R1 is an Defense Advanced Research Projects Agency (DARPA) experimental satellite, which remains largely classified.
The Minotaur I launch system is derived from converted Minuteman II ICBMs and is used to launch small satellites for the US Government. The first and second stages, taken directly from decommissioned Minuteman missiles, are mated to the Orion third and fourth stages taken from the Pegasus XL air-launched rocket family. An optional hydrazine-powered fifth stage called HAPS can be used.The Minotaur I launch system is derived from converted Minuteman II ICBMs and is used to launch small satellites for the US Government.
