The SO.4000 was France's first jet-bomber design and was preceded by two scale models, the SO.M-1 and SO.M-2. The first, a glider, was launched from a He 274 parent aircraft; the other was powered by a Rolls-Royce Derwent turbojet. The SO.4000 first flew on 16 March 1951 (it should have flown in 1950, but its complex undercarriage collapsed during taxi trials). Its
flying characteristics were bad and it was seriously underpowered. As a consequence, there were no further test flights and the aircraft was abandoned. The SO.4000's twin turbojets were mounted side by side in the centre fuselage, exhausting below the vertical tail surfaces. It was to have had two remotely controlled 20mm cannon, mounted in wingtip barbettes.
