Two more examples of the Leduc 0.10 were built, the first an identical 0.10, the other differing only by having two wingtip-mounted turbojet engines to accelerate the aircraft to the ignition speed of the ramjets. This last aircraft, designated 0.16, was first flown on 8 February 1951, but the turbojet engines were later removed.
The Leduc 016 was developed with wingtip mounted Marbore I.
