CHL version of the Channel Cats. Eric Soltys was named head coach of the team for the 2008–09 season with Paul Snell serving as his assistant. In the 2008–09 SPHL season the Havoc finished in fourth place.

With Randy Murphy taking over coaching duties in 2009–10, the Havoc finished season play in second place, earning a team-record 71 points. The Havoc entered the SPHL playoffs as the #2 seed. In round 1 Huntsville defeated the Pensacola Ice Flyers 2 games to 1. In round 2 the Havoc swept the Knoxville Ice Bears. The Havoc then went on to sweep the Mississippi Surge in the finals, winning their first SPHL President's Cup. In the
2010–11 season, the Havoc finished 3rd in the regular season and lost in the first round of the playoffs to Columbus.
In the 2018 SPHL playoffs, the fourth-seeded Havoc defeated the
Mississippi RiverKings in the Challenge Round 2-game-to-1, the
Macon Mayhem in the semifinals 2-games-to-1, and the top-seeded
Peoria Rivermen 2-games-to-1 in the finals to claim the franchise's second President's Cup. It was the first time in league history that a fourth-seeded team won the championship.
