X-47B UCAS Program Update
The X-47B Unmanned Combat Air System (UCAS) program demonstrated an acute level of precision and repeatability during at-sea trials this spring/summer. On May 21 2013, the nose gear of the X-47B landed on the same relative spot on the deck of the USS George H.W. Bush seven times consecutively. The success of this at-sea trial, and the proceeding shore-based arrestments were key milestones that led to the X-47B UCAS first-ever carrier arrestment on 10 July.
