Flaws in the "de Gaulle" have led it to using the propellers from it predecessor, the "Foch," because the ones built for "de Gaulle" never worked right.

What, the ones built for the de Gaulle wouldn't go into reverse?

It even looks like the flight deck/superstructure was designed for the carrier to launch aircraft while driving in reverse.
