Cessna Declares Speed War, Raising Ten to Mach 0.935
On Friday, Cessna announced that it has raised the top speed for its Citation Ten to Mach 0.935, which would make it the fastest civil aircraft in service once certified. This eclipses the speed of its Citation X predecessor by Mach 0.015 and the currently stated top speed of the soon-to-be-certified Gulfstream G650 by Mach 0.010.
Cessna attributes the speed increase to the Ten’s 7,034-pound-thrust Rolls-Royce AE3007C2 turbofans (more powerful than the X’s 6,442/6,764-pound C/C1s) and the addition of winglets, the latter allowing for an mtow increase to 36,600 pounds (500 pounds more than the X) and a 274-nm range extension to 3,170 nm.
“As our founder Clyde Cessna said, ‘Speed is the only reason for flying,’ so at Cessna we design, engineer, manufacture and fly the fastest civil aircraft in the world…so [customers] can work faster, more efficiently and get the job done,” said Cessna president and CEO Scott Ernest. “The Cessna team took the already powerful Citation X and made it that much better.”
Asked for comment about the Citation Ten leapfrogging the G650’s previously stated Mach 0.925 top speed, a Gulfstream spokeswoman told AIN, “We congratulate Cessna on this achievement.” The Gulfstream G650 has yet to receive full certification and thus the final performance numbers have not yet been released for the ultra-long-range jet, so time will tell how long Cessna’s claim stands.
