VFA-305 was established as Attack Squadron THREE HUNDRED FIVE (VA-305) on 1 July 1970. It was redesignated Strike Fighter Squadron THREE HUNDRED FIVE (VFA-305) on 1 January 1987, and disestablished on 31 December 1994. VA-305, a reserve squadron, was established as part of a reorganization of the reserves intended to increase the combat readiness of the Naval Air Reserve Force.

In November 1976 the squadron deployed aboard Ranger (CV 61) for the annual active duty training and as part of CVWR-30’s tactical air mobilization test and the operational readiness exercise/inspection to ensure the squadron was seaworthy and combat ready and as part of a congressional ordered Reserve Air Test. VFA-305 "Lobos" deployed aboard USS Abraham Lincoln (CVN-72) during her maiden voyage around Cape Horn as part of the reserve augmentation of active duty units during Desert Shield. Between 25 September and 20 November 1990 the squadron’s deployment with CVW-11 aboard Abraham Lincoln (CVN 72) was the first total integration of a reserve squadron with an active duty air wing for a long deployment in support of a direct fleet operational requirements. Squadron personnel participated in exercises and officer exchanges with the armed forces of Argentina and Chile and also flew drug interdiction missions during the deployment.

In 1993 the squadron added the roles of Adversary and Fleet Support to its primary mission.
