President Emmanuel Macron said he was “proud" or the "innovative” French army after seeing the flyboard designed by Franky Zapata.
An armed flyboard rider was among the highlights of this year's Bastille Day military parade in Paris on Sunday.
It was part of a demonstration of new military technology that also included ground robots.
The jet-powered flying device was designed by French inventor Franky Zapata, who was given a €1.3 million development grant.
Macron gave an approving nod as the device was demonstrated. “Proud of our army, modern and innovative,” he later tweeted.
The parade also included several flypasts.
