F-35C First In-Flight Dual Refueling

Two Lockheed Martin F-35C Lightning II carrier variant test aircraft refueled together with a Lockheed Martin KC-130 Hercules above Patuxent River, Md.

The CV aircraft, known as CF-1 and CF-2, completed the milestone as part of an F-35 flight test program that will accomplish more than 1,000 flights in 2013. Later this year, Eglin AFB, Fla., will receive its first CV aircraft joining the F-35 pilot and maintainer training program there.
