Dr. Larry Murphy, a military scientist at the rank of captain, is stationed at Area 51. He oversaw the development of the X-302 prototype craft, and he provided instructions as the ground command during its maiden flights to test the hyperspace window generator. When Earth's stargate was targeted by Anubis, Murphy also provided ground support as O'Neill piloted the X-302 craft to remove the stargate from Earth before its detonation.
