Leduc 0.10/.21
The Leduc 0.10 was a French aircraft built at the Breguet Aviation factory. The manufacturer finished it in 1947. This aircraft was one of the first to use a ramjet exclusively for power. With the design, it could not take off by itself and needed a parasite aircraft mother ship. Its successor, the Leduc 0.21, which had its first flight in 1953, contained many of the same features but refined them. Breguet added tip tanks to the wings and increased its size by about 30% compared to the Leduc 0.21. Research continued with the Leduc 022 prototype before the company ended the project in the late 1950s.
