NORFOLK (AP) -- The Navy says it has wrapped up testing with a fighter-sized drone aboard an aircraft carrier after the last of four landing attempts was scrubbed after a problem was detected.
The X-47B became the first unmanned aircraft to land aboard an aircraft carrier on July 10. It made two landings that day, while a third attempt was called off because of a computer anomaly.
On Monday, a fourth attempt at landing on the USS George H.W. Bush off the East Coast using another X-47B was scratched because of a test instrumentation issue. The Navy says the jet safely returned to Naval Air Station Patuxent River in Maryland.
The Navy said Tuesday no additional landing attempts will be made and that the Bush had returned to its homeport in Norfolk.
