On April 22, 2015, the X47B UCAV became the first unmanned aircraft to be refueled in the air. It took place off the coast of Maryland and Virginia in the Atlantic Test Ranges.
A great idea for the US navy the x-47 uav aircraft will be useful in future conflicts. The Northrop Grumman X-47B is a demonstration unmanned combat air vehicle (UCAV) designed for carrier-based operations. Developed by the American defense technology company Northrop Grumman, the X-47 project began as part of DARPA's J-UCAS program, and is now part of the United States Navy's Unmanned Combat Air System Demonstration (UCAS-D) program. The X-47B first flew in 2011, and as of 2014, it is undergoing flight and operational integration testing, having successfully performed a series of land- and carrier-based demonstrations.[2][3][4] Northrop Grumman intends to develop the prototype X-47B into a battlefield-ready aircraft, the Unmanned Carrier-Launched Surveillance and Strike (UCLASS) system, which will enter service by 2019.[5] In August, 2014, the US Navy announced that it had integrated the X-47B into carrier operations alongside manned aircraft.[6]
Design and development
Origins[edit]
The US Navy did not commit to practical UCAS efforts until 2000, when the service awarded contracts of US$2 million each to Boeing and Northrop Grumman for a 15-month concept-exploration program.[7] Design considerations for a naval UCAV included dealing with the corrosive saltwater environment, deck handling for launch and recovery, integration with command and control systems, and operation in an aircraft carrier's high-electromagnetic-interference environment. The Navy was also interested in procuring UCAVs for reconnaissance missions, penetrating protected airspace to identify targets for following attack waves.[8]
The J-UCAS program was terminated in February 2006 following the US military's Quadrennial Defense Review. The US Air Force and Navy proceeded with their own UAV programs. The Navy selected Northrop Grumman's X-47B as its unmanned combat air system demonstrator (UCAS-D) program.[citation needed] A new weapon system will not be developed for the X-47B, but it will be able to carry existing weapons,[9] and has a full-sized weapons bay. To provide realistic testing, the demonstration vehicle is the same size and weight as the projected operational craft.[10][11][12]
The X-47B prototype rolled out from Air Force Plant 42 in Palmdale, California, on 16 December 2008. Its first flight was planned for November 2009, but the flight was delayed as the project fell behind schedule. On 29 December 2009, Northrop Grumman oversaw towed taxi tests of the aircraft at the Palmdale facility,[13] with the aircraft taxiing under its own power for the first time in January 2010.
Flight testing
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.[14][15] The aircraft first flew in cruise configuration with its landing gear retracted on 30 September 2011.[16] A second X-47B demonstrator, designated AV-2, conducted its maiden flight at Edwards Air Force Base on 22 November 2011.[17]
The two X-47B demonstrators were 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.[17][18] However, the aircraft performed so consistently that the preliminary tests stopped after 16 flights.[19] The aircraft will be used to demonstrate carrier launches and recoveries, as well as autonomous inflight refueling with a probe and drogue. The X-47B has a maximum unrefueled range of over 2,100 nautical miles (3,900 km), and an endurance of more than six hours.[20] In November 2011, the Navy announced that aerial refuelling equipment and software would be added to one of the prototype aircraft in 2014 for testing.[21] The demonstrator aircraft will never be armed.[19]
