Warp Five Complex

The Warp Five Complex was a research and development facility built in 2119 near Bozeman, Montana on Earth. 

The loss of the USS Bonaventure years earlier was a factor in driving Zefram Cochrane to create the complex and push the limits of warp technology. Cochrane was present for the building's dedication, one of his last public appearances before disappearing later that same year. 

Henry Archer worked at the Warp Five Complex from its start, and did much of his work on the Warp Five engine there.
