Nighthawk is a steel Vekoma flying roller coaster at Carowinds in Charlotte. North Carolina. It originally opened as Stealth at California's Great America on April 1, 2000. Stealth was the first flying roller coaster of its kind in the world. Paramount closed the ride in 2003 after deciding to relocate the roller coaster. It reopened as BORG Assimilator – the first coaster in the world to be themed to Star Trek – at Carowinds on March 20, 2004. After Cedar Fair purchased Carowinds in 2006, Paramount themes were soon removed from the park. As a result, the ride became known as Nighthawk.
