X-302 Project manager. Murphy vouched that this new model of fighter was vastly superior to the failed X-301 -- which sent Colonel Jack O'Neill and Teal'c spiraling into deep space.
Murphy directed both Abydos One and Star Flight missions with the X-302 through a video communications link that was patched into the S.G.C. briefing room and the cockpit of the 302.
