- El Leduc 0.21 va ser una aeronau de recerca construïda per a França el 1953 per tal de refinar la propulsió dels estatoreactors. Inicialment proposat com 0.20, era essencialment igual al seu predecessor, el Leduc 0.10, però millorat, amb tancs de combustible afegits a les ales. El Leduc no era capaç d'enlairar-se per els seus propis medis, ja que, tan sols funcionava a partir dels 350 km/h i, per tant, havia de ser llençat des de l'aire per un avió quadrimotor llançadora. Dos unitats van ser construïdes i van completar un programa molt detallat de proves de vol entre 1953 i 1956 per desenvolupar controls d'acceleració automatitzats i viables per els estatoreactors. En total es van realitzar un total de 284 vols lliures. Dissenyat només per velocitats subsòniques, el 0.21 va assolir una velocitat màxima de Mach 0.95. (ca)

- The Leduc 0.21 was a research aircraft built in France in 1953 to refine the practicalities of ramjet propulsion. Initially proposed as the 0.20, it was essentially similar to its predecessor, the Leduc 0.10, but scaled up by around 30%, with tip tanks added to the wings. It was not capable of take-off under its own power, and had to be carried aloft and released. Two examples were built and completed a very detailed flight test program from 1953 to 1956 to develop automated, operationally viable throttle controls for the ramjet. This included a total of 284 free flights. Designed for subsonic speeds only, the 0.21 reached a top speed of Mach 0.95. (en)
