The X-47B (previously noted) executed a successful first flight at Edwards AFB, California last week.

The X-47 is a Navy/Northrop technology demonstrator intended to test (and demonstrate) the ability of an unmanned aircraft to land on an aircraft carrier.  The aircraft somewhat resembles a miniature B-2, and is ultimately intended to portend the UCAV, or Unmanned Combat Aerial Vehicle — the ability to conduct autonomous deep strike missions.

The Navy Times has an article and a video of the flight.
