The Baltimore Blast were founded by North Carolina-based software executive Bill Stealey as the Baltimore Spirit at the end of July 1992 and joined the National Professional Soccer League. The team replaced the earlier Baltimore Blast, who folded along with the original Major Indoor Soccer League. When the team was purchased by Ed Hale, a former owner of the original team, the Spirit were renamed the Blast on July 10, 1998 (Hale had the rights to the Blast name, hence the reason why the team decided to change its name) and joined the new MISL II in 2001. After the MISL II folded in 2008, the team announced it would be joining the new National Indoor Soccer League, which would later acquire the rights to, and became, the third version of the MISL.
One day after the 2013-2014 MISL Championship final, USL President Tim Holt announced a number of teams would not be returning to the MISL the following year. In April 2014 it was officially announced the Blast would be one of six teams joining the PASL (later renamed the MASL) in the 2014-2015 season.
