Dassault Ouragan
The Dassault M.D.450 Ouragan (French: Hurricane) was a 1940s French jet fighter-bomber aircraft. While technologically unremarkable, the Ouragan played a key role in resurgence of the French aviation industry after World War II.
Design and development
As citizens of an occupied country, the French were not able to contribute significantly to the great strides made in aircraft design made during World War II. After the war, aviation designer Marcel Dassault was eager to re-establish the aviation industry with an all-French jet fighter, which was outlined in 1947. The government response to the proposal was positive but did not result in a development contract, so Dassault decided to proceed on his own.
Detailed design work on the new aircraft, which was given the designation M.D. (Marcel Dassault) 450, began in December 1947, with construction beginning on 7 April 1948 at Dassault's factory in Saint-Cloud. A French government contract for three prototypes followed on 29 June, and the first Ouragan fighter flew on 28 February 1949 with Constantin Rozanoff at the controls. The M.D.450-01 prototype lacked pressurization, armament, and the distinctive wingtip fuel tanks. Powered by a Hispano-Suiza-licensed Rolls-Royce Nene 102 centrifugal-flow jet engine generating 22.27 kN (2,270 kp/5,000 lbf) of thrust, the aircraft reached a top speed of 980 km/h (529 knots, 609 mph) and initial climb rate of 43 m/s (8,465 ft/min) in service trials in 1949. The 450 liter (118.9 US gal) wingtip tanks that would become the indelible feature of all Ouragans first appeared in December 1949. The pressurized second prototype, M.D.450-02, climbed to 15,000 m (49,213 ft), while the third prototype, M.D.450-03, was used in weapons trials with 15 mm and later 20 mm cannon.
The Ouragan was inspired by American designs,[citation needed] and its general layout was similar to the Republic F-84 Thunderjet, while the thin low-set straight wing was similar to that of the Lockheed F-80 Shooting Star and the F-84.
In July 1949, French Air Force ordered 15 pre-production aircraft (later reduced to 12), which were eventually used for evaluation of various engines (including SNECMA Atar), armament schemes, and payloads. On 31 August 1950, Dassault received an order for 150 production Ouragans, with an additional 200 ordered in the following years.
Operational history
The first production Ouragan flew on 5 December 1951. The type entered service with the French Air Force in 1952, replacing the British De Havilland Vampire. The first 50 Ouragans were built as M.D.450A with the Nene 102 engine; the rest were M.D.450B with a Hispano-Suiza-built Nene 104B engine, lighter than the Nene 102 and with slightly greater thrust. Wingtip fuel tanks were fitted as standard in both variants.
Pilots found the Ouragan to be generally pleasant to fly and a stable gun and rocket platform, although due to its short-coupled fuselage, the aircraft had a tendency to snap into a spin in tight turns. However, for two years, the Ouragon successfully performed with la Patrouille de France aerobatic team.
In French service, the Dassault Mystère IV completely replaced the Ouragan by 1961.
India
On 25 June 1953, India ordered 71 Ouragans with the slightly uprated Nene 105 engine, with most of the order delivered that year. Additional orders brought the total to 104, though only the first 71 were new-build aircraft. The Indians named the aircraft Toofani (Hindi: Hurricane). As was the case in France, the Ouragan was replaced in front-line service by the Mystère IVA by 1958. The Indian Toofanis faced combat in 1961, when they performed air strikes against the Portuguese colony of Diu on the western coast of India.
Israel
In contrast to France and India, the Israeli Air Force was an enthusiastic Ouragan user. Seeking to augment its jet aircraft force of British Gloster Meteors, IAF initially considered French Dassault Mystère IIC and Canadian-built F-86 Sabre Mk.6 fighters. Due to development problems with the Mystère and a Canadian embargo on the Sabres, the order was changed to Mystère IVAs, with a batch of Ouragans purchased as a stop-gap measure. By 1955, the IAF had received at least 75 aircraft, comprising a mix of newly-built and retired French Air Force examples.
Israeli Ouragans entered combat on 12 April 1956, shooting down an Egyptian Vampire.[1] At the onset of the Suez Crisis on 29 October 1956, Ouragans shot down an additional four Vampires. The two documented encounters with Soviet Mikoyan-Gurevich MiG-15 fighters (also powered by the Nene engine but with a more modern swept wing) ended with one Ouragan surviving several 37 mm (1.46 in) cannon hits to fly the next day and one MiG-15 being heavily damaged after it entered a turning dogfight with the Ouragans.[1] The poor training of the Egyptian pilots who were consistently unable to realize their advantage in numbers as well as the MiG-15's speed and climb characteristics helped Ouragans to survive despite their inferior performance.[1] On 31 October, a pair of Ouragans armed with rockets strafed the Egyptian destroyer Ibrahim-el-Awal (ex-HMS Mendip), resulting in the capture of the ship.
The Ouragans were relegated to advanced training shortly after the Suez Crisis, although they saw more combat in the 1967 Six-Day War. In 1975, the IAF sold 18 Ouragans to El Salvador, where they remained in service until the late 1980s.
El Salvador
In the wake of the Football War of 1969, El Salvador began a concerted push to modernize its air force. Unable to buy combat aircraft from the United States due to a US government arms embargo, the Salvadorans found surplus Israeli Ouragans for sale on the international arms market. These aircraft were refurbished by the Israelis and were delivered to El Salvador between 1973 and 1978.
El Salvador's Ouragans saw extensive combat during the Salvadoran Civil War of 1980-1992. Salvadoran Ouragans flew strike missions against communist FMLN forces, operating from Ilopango airport located near the capital city of San Salvador. As El Salvador is not a large country and combat radius was not a pressing concern, Salvadoran Ouragans in combat usually operated with their wingtip fuel tanks removed in order to save weight and allow for greater weapons loads.
An FMLN sapper attack against Ilopango in 1982 destroyed several Ouragans and accelerated the push to supplant, and eventually replace, the Ouragans with American-made Cessna A-37 Dragonfly aircraft, which were made available after the Reagan Administration dropped the arms embargo. The remaining Ouragans served on for several more years, but were all retired by war's end.
Salvadoran Ouragans have been pictured in several camouflage schemes, and it is possible that during the war the Ouragan fleet operated in colors that were never completely standardized.
At least one survivor of El Salvador's Ouragan fleet is currently on static display, at Ilopango.
Variants
- M.D.450A
- First 50 production aircraft, Nene 102 engine.
- M.D.450B
- Hispano-Suiza-built Nene 104B engine, revised two-section nose landing gear doors as the original four-section design was prone to damage when the cannons were fired.
- M.D.450R
- Reconnaissance variant, only one built.
- M.D.450-30L
- One pre-production prototype fitted with a SNECMA Atar 101b engine, air intakes on the sides of the fuselage, and two 30 mm DEFA cannon.
- Barougan
- Four production aircraft modified for rough-field operation with the two-wheel main landing gear with low-pressure tires retracting into a fairing added under the wing roots, and a brake parachute. The configuration was intended for operations in Algeria, and the nickname came from the Arab word "baroud," meaning "battle." First flight 24 February 1954. Despite good performance, the project was abandoned in 1958 with two aircraft converted back to standard Ouragans.
Operators
Survivors
A number of MD.450 Ouragan examples are preserved in France including #251 and #450/"4-US", part of the jet aircraft collection at Chateau Savigny-lès-Beaune. The Musee de l'Air et de l'Espace at Le Bourget Airport has #154/ "4-LT" painted in a colorful "Indian-head" scheme but a previous code is just visible under the 4-LT markings. Ouragan #214/"UG," previously stored, is exhibited in the "Patrouille de France" paint scheme at the "Musée Européen de l'Aviation de Chasse," Montélimar. Israeli Air Force Ouragan "113," a combat veteran and survivor of the 1956 Suez War and 1967 Six-Day War, is on outdoor display at the Israel Air Force Museum. An MD.450 Ouragan (Toofani), "IC 554," is on display at the Indian Air Force Museum, Palam, New Delhi. It was painted earlier in grey-green camouflage but now appears in natural metal in No. 47 "Black Archers" Squadron markings.
