摘要

There is no doubt that the first-ever arrested landing of an unmanned aircraft on a carrier deck, a feat achieved last week by the U.S. Navy, will be among the most notable events in aerospace history. But the dazzling display 70 mi. off the U.S. East Coast was followed by challenges, underscoring the complexity of achieving the Navy's longtime goal of marrying the power projection of its aircraft carrier fleet with the endurance and range of unmanned aircraft. Anomalies with the Unmanned Combat Air System's (UCAS) ship controls and navigation computer-experienced after the seminal landing-point to areas that will need work as the Navy eyes a carrier UAV purchase as soon as next year. The Navy's second Northrop Grumman X-47B demonstrator, Salty Dog 502, made aviation history July 10 with the landing, which Navy Secretary Ray Mabus said helps to "make sure that we keep the technological edge" as countries such as China work to build stealthy aircraft and unmanned vehicles.
