After the success of the Ouragan, Dassault was working on a more advanced
machine based on it, which would take to the air in early 1951 as the MD.452
wing and modified tail surfaces. Two further prototypes followed, powered by the
Rolls-Royce Tay 250 centrifugal-flow turbojet, an improved version of the
Rolls-Royce Nene, built under license by Hispano-Suiza, and rated at 28.0 kN
(6,300 lbf) thrust.
the Tay and armed with four 20 mm (0.787 in) Hispano cannon; and then four
aircraft to break Mach 1 in controlled flight (in a dive), on 28 October 1951.
nine of which were fitted with the SNECMA Atar 101C axial-flow turbojet, rated
at 24.5 kN (5,500 lbf) thrust, while two were experimentally fitted with the
afterburning Atar 101F, with an afterburning thrust of 37.3 kN (8,400 lbf).

flying in June 1954, being delivered in October of that year. The production
aircraft featured the twin 30 mm (1.181 in) DEFA cannon, an Atar 101D turbojet
with 29.4 kN (6,600 lbf) thrust, increased tail sweep, and revised intake
trunking and internal fuel tank arrangement. Top speed was 1,030 km/h (560 kn;
640 mph) at low level. Details of external stores are unclear, but a reasonable
assumption would be that they were similar to those of the Ouragan.

two-seat cockpit, to continue development of the MD 451 Aladin initiated with
the MD 450-30-L modified Ouragan. First flown on 18 July 1952 the sole IIIN was
never fitted with a radar and was used for ejection seat trials once development
of the MD 451 was abandoned. The second and third prototypes were cancelled
before completion.
