AIM 120A air-to-air missile

AIM 120A air-to-air missiles were missiles installed on the X-301 by the Tau'ri as a countermeasure to Goa'uld attack. The X-301 carried a complement of 2 missiles which were used in a plan to slingshot the craft around Jupiter using the planet's own gravity. Suffice it to say the plan failed as the missile provided insufficient thrush to move the craft.
