During another underway period, "George H.W. Bush" conducted at-sea tests for X-47B unmanned drone in the Atlantic Ocean, including the first time that an unmanned drone has been catapulted off an aircraft carrier on the morning of 14 May 2013 ("pictured"). On 17 May 2013, another first was achieved when the X-47B performed touch-and-go landings and take-offs on the flight deck of "Bush" while underway in the Atlantic Ocean. Also during this two-week underway period, the aircraft carrier tested a new torpedo self-defense system, as well as completed more than 115 launches and landings in assessing a new precision landing system, before returning to Norfolk on 24 May 2013.
