Two of the United States ' most recognizable military aircraft -- a pair of B-2 stealth bombers -- caught the eyes of residents as they arrived in Europe this week for training . `` They seem to defy science ! '' said one Twitter user in Cirencester , England , who saw one of the stealth bombers in flight . The bombers ' unique radar-evading design always draws attention , as does this training mission in particular , which comes at a time of conflict in Ukraine . An Air Force news release about the mission did not mention the Ukraine crisis , but U.S. fighter jets have previously been deployed to Europe on similar training missions to show support for NATO allies . The mission for the pair of stealth bombers , the Air Force said , is to conduct flights in Europe and to become familiar with air bases and operations in the area . `` This deployment of strategic bombers provides an invaluable opportunity to strengthen and improve interoperability with our allies and partners , '' said Adm. Cecil Haney , commander of U.S. Strategic Command . `` The training and integration of strategic forces demonstrates to our nation 's leaders and our allies that we have the right mix of aircraft and expertise to respond to a variety of potential threats and situations . '' The B-2s are assigned to the 509th Bomb Wing at Whiteman Air Force Base in Missouri . `` Just saw a Stealth Bomber fly over our house , '' another resident said on Twitter . `` Amazing aircraft . My son wanted to know if Batman was flying it . ''
