On 26 November 2012, the X-47B began its carrier-based evaluation aboard the USS Harry S. Its first land-based catapult launch was conducted successfully on 29 November 2012.

In June 2012, AV-2 arrived at Patuxent River to begin a series of tests, including arrested landings and catapult launches, to validate its ability to conduct precision approaches to an aircraft carrier. In May 2012, AV-1 began high-intensity electromagnetic interference testing at Patuxent River, to test compatibility with planned electronic warfare systems. In 2012, Northrop Grumman tested a wearable remote control system, designed to allow ground crews to steer the X-47B while on the carrier deck.

In November 2011, the Navy announced that aerial refuelling equipment and software would be added to one X-47B in 2014 for testing they also affirmed that the demonstrators would never be armed. The Navy decided to have them demonstrate carrier launches and recoveries, as well as autonomous inflight refueling with a probe and drogue. However, they performed so consistently that preliminary tests ended after 16 flights. The two X-47Bs were initially planned to have a three-year test program with 50 tests at Edwards AFB and NAS Patuxent River, Maryland, culminating in sea trials in 2013. A second X-47B demonstrator, designated AV-2, conducted its maiden flight at Edwards Air Force Base on 22 November 2011. It first flew in cruise configuration with its landing gear retracted on 30 September 2011.
The first flight of the X-47B demonstrator, designated Air Vehicle 1 (AV-1), took place at Edwards Air Force Base, California, on 4 February 2011.

On 29 December 2009, Northrop Grumman oversaw towed taxi tests of the aircraft at the Palmdale facility, with it taxiing under its own power for the first time in January 2010.
Its first flight was planned for November 2009, but the project fell behind schedule. The X-47B prototype rolled out from Air Force Plant 42 in Palmdale, California, on 16 December 2008. To provide realistic testing, the demonstrator was built to be the same size and weight as the projected operational craft, with a full-sized weapons bay capable of carrying existing missiles. The Navy selected Northrop Grumman's X-47B as its unmanned combat air system demonstrator (UCAS-D) program. The US Air Force and Navy proceeded with their own UAV programs. The J-UCAS program was terminated in February 2006 following the Quadrennial Defense Review. Northrop Grumman's proof-of-concept X-47A Pegasus, which provided the basis for the X-47B, first flew in 2003. The Navy was interested in using UCAVs for reconnaissance, to penetrate protected airspace and identify targets for follow-on attacks. Design considerations for a naval UCAV included dealing with the corrosive saltwater environment, deck handling for launch and recovery, command and control system integration, and operation in an aircraft carrier's high- electromagnetic-interference environment. The US Navy did not commit to practical UCAS efforts until 2000, when it awarded contracts of US$2 million each to Boeing and Northrop Grumman for a 15-month concept-exploration program.

In August 2014, the US Navy announced that it had integrated the X-47B into carrier operations alongside manned aircraft, and by May 2015 the primary test program was declared complete. The X-47B first flew in 2011, and as of 2015, its two active demonstrators have undergone extensive flight and operational integration testing, having successfully performed a series of land- and carrier-based demonstrations. The X-47B is a tailless jet-powered blended-wing-body aircraft capable of semi-autonomous operation and aerial refueling. Developed by the American defense technology company Northrop Grumman, the X-47 project began as part of DARPA's J-UCAS program, and subsequently became part of the United States Navy's Unmanned Combat Air System Demonstration (UCAS-D) program. The Northrop Grumman X-47B is a demonstration unmanned combat aerial vehicle (UCAV) designed for aircraft carrier-based operations.
