X-301
The X-301 fighter-interceptor is Earth's first attempt at building a fighter capable of space travel and orbital defense against the Goa'uld. It is featured in the episode "Tangent". The X-301 is constructed in the Area 51 from a combination of Earth components and parts salvaged from two Goa'uld death gliders from the Apophis motherships. The X-301 is equipped with a Goa'uld inertial propulsion system capable of nullifying any g-force on pilot, stealth technology that hides it from radar, and two naqahdah-enhanced AIM-120 AMRAAM air-to-air missiles. It was mentioned that they would be effective against the Goa'uld Motherships if armed with shield modulators, however, no missiles fired by Earth ships were ever seen to penetrate through Goa'uld shields, so they may never have had that form of technology (working), and it was only mentioned in reference to the X-301, not the 302.
The first test flight is conducted by Jack O'Neill and Teal'c, with the callsign "Digger One". The test almost proves fatal when an undiscovered booby trap planted by Apophis activates and launches the ship towards open space and towards Chulak, the home world of Apophis. O'Neill and Teal'c are rescued just before their life support runs out by Jacob Carter in a Goa'uld cargo ship.
