Since the end of the Cold War, numerous unmanned aerial vehicles (UAVs) featuring the flying wing have been produced. Nations have typically used such platforms for aerial reconnaissance; such UAVs include the Lockheed Martin RQ-170 Sentinel,[40][41] the Northrop Grumman Tern,[42][43] and the Nanning Huishi Flying wing. Civilian companies have also experimented with UAVs, such as the Facebook Aquila, as atmospheric satellites.[44][45] Various prototype unmanned combat aerial vehicles (UCAVs) have been produced, including the Dassault nEUROn,[46] the Sukhoi S-70 Okhotnik-B,[47] and the BAE Systems Taranis.[48]
