BAGHDAD, Iraq (CNN)  -- The troubled Blackwater era ends in Iraq on Thursday as another firm takes over the once-dominant company's security services contract in Baghdad. A helicopter for the private security firm then known as Blackwater flies over Baghdad in October 2003. Triple Canopy, a Herndon, Virginia-based company, picks up the expiring contract of the security firm formerly known as Blackwater Worldwide, which changed its name to XE a few months ago. The U.S. State Department decided not to renew XE's contract in January. "When the U.S. government initially asked for our help to assist with an immediate need to protect Americans in Iraq, we answered that call and performed well," XE spokeswoman Anne Tyrell said in a statement Wednesday. "But we always knew that, at some point, that work would come to a close."
