The Ann Arbor Science Fiction Association is a not-for-profit corporation that grew out of the Stilyagi Air Corps, which itself was a continuation of the University of Michigan Science Fiction Club, founded in the 1970s. The first convention organized by the group was the A2 Relaxacon in 1973, followed by the first ConFusion the following year.

Every year since then, ConFusion has been a cornerstone of the Detroit-area convention scene. AASFA provides guidance and support to the convention, and appoints the ConChair every year. AASFA also sponsors other activities, including a late winter voting party and a summer picnic.

The Stilyagi Air Corps continues as a social organization with an e-mail discussion list and frequent social events.
