Northrop Grumman built the X-47/Pegasus unmanned combat aerial vehicle (UCAV) demonstrator under a $12 million DARPA/Navy contract. It is intended to evaluate technologies and concepts for a possible follow-on carrier-capable, naval UCAV (UCAV-N) for fielding in the post-2010 timeframe. The UCAV-N is to perform three missions: surveillance, strike, and suppression of enemy air defenses (SEAD). The single X-47 flight test aircraft was formally rolled out in July, 2001.
