Northrop Grumman's X-47B is part of the U.S. Navy's Unmanned Carrier Air System Demonstration (UCAS-D). NAVAIR's PMA-268 is responsible for managing the UCAS-D program, which was created to mature technologies for a carrier-suitable, low observable unmanned air system (UAS).
The first flight of the X-47B took place in February 2011 at Edwards Air Force Base in California.
In November 2012, the aircraft's wireless Control Display Unit was tested to practice taxing the aircraft in the confined spaces it will face onboard an aircraft carrier's flight deck and hangar. In December 2012, the X-47B completed a series of deck handling and taxi tests over a two week period at sea aboard USS Harry S. Truman (CVN 75) in preparation for take off and landing trials in early 2013.
The aircraft completed its first catapult launch from USS George H W Bush (CVN 77) on 14 May 2013 and touch and goes on the same ship on 17 May. On 10 July 2003, UCAS-D call-sign "Salty Dog 502" completed two arrested recoveries, or "traps," on the deck of USS George H.W. Bush (CVN 77). The X-47B prototypes are expected to embark aircraft carriers again in late 2013 and 2014. The X-47Bs will also conduct the first-ever aerial refueling of a robotic aircraft in the with a planned aerial refueling demonstration in the fall of 2014.
The X-47B is also a contender for the Navy's follow-on UCLASS competition.

20 November 2013 - For the first time, both Navy X-47B Unmanned Combat Air System Demonstrators participated in tests with a single aircraft carrier. While one remained onboard USS Theodore Roosevelt (CVN 71), the second conducted flight operations.

X-47B Integration Testing on USS Theodore Roosevelt
10 November 2013 - The X-47B Unmanned Combat Air System Demonstrator (UCAS-D) conducted flight operations aboard the aircraft carrier USS Theodore Roosevelt (CVN 71).
The event, the most-recent in a series of carrier-based tests, demonstrated the integration of the latest in naval aviation technology with the most advanced and capable carrier.
This weekend's tests demonstrated the X-47B's ability to integrate with the carrier environment. The aircraft performed precise touch and go maneuvers on the ship to generate data that characterizes the environment in close proximity of the carrier flight deck. In addition, the aircraft took part in flight deck handling drills, completed arrested landings and catapult launches. Mission operators monitored the aircraft's autonomous flight from a portable command and control unit from Theodore Roosevelt's flight deck during each of its 45-minute flights.

X-47B Program Completes Centennial Flight
18 September 2013 - The X-47B (AV-2) conducted the 100th flight for the Navy's Unmanned Combat Air System Demonstration (UCAS-D) program today at Patuxent River Air Station. The Navy UCAS program successfully completed all objectives for the carrier demonstration phase with the X-47B in July. During three at-sea periods over eight months, the X-47B conducted a total of 16 precision approaches to the carrier flight deck, including five planned tests of X-47B wave-off functions, nine touch-and-go landings, two arrested landings and three catapult launches.

X-47B Surrogate Continues Aerial Refueling Testing
11 September 2013 – According to Naval Air Systems Command, the Navy and Northrop Grumman completed another phase of its Autonomous Aerial Refueling (AAR) test for the Unmanned Combat Air System Demonstration (UCAS-D) program.
From late August to 6 September in Niagara Falls, NY, a Calspan Aerospace Learjet outfitted with an inert refueling probe, the X-47B’s navigation, command and control, and vision processor hardware and software conducted a series of flights flying autonomously behind an Omega K-707 Tanker.
Captain Jaime Engdahl, UCAS program manager noted that the “the AAR segment of the UCAS-D program is intended to demonstrate technologies, representative systems, and procedures that will enable unmanned systems to safely approach and maneuver around tanker aircraft. We are demonstrating both Navy and Air Force style refueling techniques.”
“Demonstrating AAR technologies and standard refueling procedures is the next logical step for our demonstration program. The team has shown that we can use the same systems architecture, Rockwell Collins TTNT datalink, and Precision Relative GPS (PGPS) algorithms to extend the concept of distributed control of autonomous systems from the aircraft carrier to the airborne refueling environment,” said Engdahl. “The initial tests showed excellent system integration as well as good navigation and vision system performance.”
Previous flight tests with the Lear configured in this manner occurred in late 2011 and early 2012. Later this fall, the Lear surrogate will demonstrate end-to-end AAR concept of operations with a complete autonomous rendezvous, approach, plug, and safe separation utilizing its installed X-47B software and hardware.
