The GQM-163 Coyote is a supersonic sea skimming target built by Orbital Sciences and used by the United States Navy as a successor to the MQM-8 Vandal. Orbital's proposal was chosen over the MA-31, a joint venture between Boeing and Zvezda-Strela. Orbital was awarded their contract for the development of the Coyote SSST in June 2000.

The Coyote is initially boosted by a Hercules MK-70 booster, of similar design to those used by the now obsolete RIM-67 Standard ER missiles. After the booster stage is expended the missile switches to an Aerojet MARC-R-282 solid-fuel rocket /ramjet engine for sustaining its flight. [2][3][4]
