The 3.5-hour flight saw The Boeing-built aircraft undergo operational checks on engines, flight controls, and environmental systems.
USAF KC-46 System programme manager colonel John Newberry said: “Today’s flight is another milestone for the airforce/Boeing team and helps move us closer to delivering operational aircraft to the warfighter.”
The airborne operational checks were conducted as part of the Federal Aviation Administration (FAA) approved flight profile.
Prior to subsequent flights, the team of test pilots from Boeing will conduct a post-flight inspection and calibrate instrumentation.
Boeing KC-46A tanker vice-president and programme manager Mike Gibbons said: “We still have some tough work ahead of us, including completing our FAA certification activities, but the team is committed to ensure that, upon delivery, this tanker will be everything our customer expects and more.”
