X-47B engages tanker to prepare for refuelling test
The X-47B UCAS-D on 15 April connected with the fuel probe of a refuelling aircraft in flight, the US Navy (USN) announced on 16 April.
The X-47B connected with an Omega Aerial Refueling Services K-707 tanker, but did not receive fuel during the test. The effort marked a final preparation for an actual in-flight refuelling of the UCAS-D.
In that final test the X-47B is expected to use a new optical sensor to guide its fuel probe into the tanker aircraft's drogue. janes
