Dr. Larry Murphy was assigned as the project lead in the development of the X-302 space-worthy fighter jet which used naquadria to generate a hyperspace window. He was introduced in the episode, 6.01 "Redemption Part 1". Dr. Murphy was the engineer to present the new spacecraft to SG-1. The X-302 was used and subsequently destroyed to save the Earth from Anubis' attack on the stargate.
