The squadron's first predecessor is the606th Bombardment Squadron, which was activated as aheavy bomber training unit duringWorld War II. It was disbanded in 1944 when theArmy Air Forces reorganized its training and support units in the United States to make more effective use of manpower.
The 306th Squadron was activated in 1951 and performedair refueling until it was inactivated in 1973. It was activated a second time in 1984. The two squadrons were consolidated into a single unit the following year.
However, theArmy Air Forces was finding that standard military units like the 606th, which were assigned personnel and equipment based on relatively inflexibletables of organization were not proving well adapted to the training mission. Accordingly, it adopted a more functional system in which each base was organized into a separate numbered unit, which was manned and equipped based on the station's requirements.[4] The 606th Squadron was disbanded, and along with operational and supporting units at March was used to form the 420th AAF Base Unit (Bombardment Replacement Training Unit-Heavy).[1][5]
