F-35A Testing Moves Into High Speeds
Published: 13 June 2011

Meanwhile, the Edwards test pilots are also pushing the F-35
into high-speed tests.
Within the past month, they have moved from a top speed of Mach 1.3 to
Mach 1.53 at 39,000 feet. Soon, the pilots hope to hit the aircraft's
maximum speed of 700 knots.
"We're taking baby steps out there to make sure our air data system is
meeting our predictions, so therefore we don't just jump out to
Mach 1.6," Griffiths said.

おお既に普通にマッハ1.3が出てるんだな
高度4万フィートの音速は580ノットだから700ノットだとMach1.2
