 The last F-102A finally left ANG service in October 1976, when the 199th FIS of the Hawaii ANG traded in their Delta Daggers for F-4C Phantom II and the 154th became a Tactical Fighter Group.The F-4C was a workhorse tactical fighter-bomber during the Vietnam War, and could also be used as an effective interceptor.The Hawaii ANG used the Phantom in both roles, employing it during training exercises with Army and Marine units in ground exercises, as well as retaining the standing air defense alert at Hickam.
