F-35A Testing Moves Into High Speeds By DAVE MAJUMDAR : 13 June 2011

"...The F-35's ability to carry weapons and a large fuel load inside its own skin makes the plane far less draggy on a combat mission than the F-16 or F/A-18, which sling missiles, bombs and fuel tanks below their wings and fuselage, Griffiths said . Moreover, a combat-laden F-16 loses much maneuverability, whereas the F-35 is barely affected by carrying 18,000 pounds of internal fuel and 5,000 of internal weaponry. "It flies fantastic," he said. Griffiths declined to compare the F-35 to the F-16s he once flew. But he noted the F-16 is only technically an 800-knot and Mach 2.02 aircraft. In practical terms, most pilots will never see speeds above 700 knots or Mach 1.6 because real-world load-outs don't allow it. The F-35 can't supercruise like the F-22 Raptor, but the test pilots have found that once they break the sound barrier, supersonic speeds are easy to sustain. "What we can do in our airplane is get above the Mach with afterburner, and once you get it going ...
you can definitely pull the throttle back quite a bit and still maintain supersonic, so technically you're pretty much at very, very min[imum] afterburner while you're cruising," Griffiths said. "So it really does have very good acceleration capabilities up in the air." Retired Lt. Gen. David Deptula, formerly the Air Force intelligence chief and a veteran F-15 pilot, said having that kind of capability is a huge advantage. "I'm real happy to hear that in fact is the case, because speed gives you a variety of advantages," he said. "It allows you to employ your air-to-air missiles from a range much greater than otherwise would be the case."
Though the F-35's maximum speed is Mach 1.6, the F-35 test program will eventually push the jet a little beyond that limit to make sure operational pilots have a margin of safety, Griffiths said...."
