The CT52 had no digital systems, relying on older wet-film cameras. Very much like the British V Bomber force, the Mirage IV was part of a three way nuclear deterrent based around manned aircraft… [51] The main radar and electronics suite were removed and replaced by newer counterparts; other modified systems included the navigation system, flight control system, and various elements of the cockpit. [31] Fuel was contained within integral tanks within the wings, as well as a double-skinned section of the fuselage between and outboard of the inlet ducts, underneath the ducts and engines, and forward of the main spar of the tail fin; this provided a total internal capacity of 6,400 kilograms (14,000 lb). here to keep this site going. ", "Aviation Militaire: Dassault Mirage IV. [38][55], In August 1985, a French proposal that would have seen Mirage IVPs stationed at air bases inside neighbouring West Germany was made public; this deployment would have marked a significant philosophical departure from traditional French nuclear defence policy. [2] According to aviation authors Bill Gunston and Peter Gilchrist, the specification's inclusion of supersonic speed was "surprising" to many at the time. [47], To improve survivability, the French Air Force began dispersing Mirage IVs to pre-prepared rough strips during the 1960s; while the use of hardened bunkers had been assessed, it was found to be financially impractical. Lacking any operational objective in these cases, they were nevertheless very spectacular crowd-pleasers.”, “Having never, during the Cold War, carried out a real operational mission, none of the training missions deserve any special classification. The 12 rockets hung under the belly of the Mirage IV required an additional thrust of more than 5 tonnes, corresponding to about 2/3 power of a single engine. This relatively thinner wing was permitted by the aircraft's greater size and was better suited … When fully built up, the force consisted of three wings. After the acceptance of the Mirage IV 01 prototype, Dassault presented three proposals for the future supersonic bomber, designated as Mirage IV-A, IV-B and IV-C, with different dimensions and powerplants.Proposals B and C were rejected because they were too expensive, so the IV … Climb rateE. The night flight refuelling in a dense mass of storm clouds with heavy turbulence. [27] Some aviation journalists claim that the rejection of the Mirage IV* may have dampened French interest in joint Anglo-French cooperation. These aircraft were designated Mirage IVR for reconnaissance. For very low altitude missions, speed was considered to be sufficient protection, since there was nothing else. [57] EB 2/91 was disbanded and EB 1/91 was redesignated Escadron de Reconnaissance Stratégique (Strategic Reconnaissance Squadron),[citation needed] using five remaining Mirage IVPs based at Mont-de-Marsan; the remaining aircraft were stored at Chateaudun. The Mirage IVA was an all-metal aircraft made mostly of aircraft aluminum alloys. [3], Dassault's resulting prototype, dubbed Mirage IV 01, looked a lot like the Mirage IIIA, even though it had double the wing surface, two engines instead of one, and twice the unladen weight. That said, outside the strict framework of its mission, and outside the limits set by the operating instructions, it gave the feeling of having amazing possibilities considering its weight. The Mirage IV was replaced as a nuclear platform by the Mirage 2000 N in 1996 and finally retired as a reconnaissance aircraft for the French Air Force in 2005. Gunston, Bill. The fourth prototype Mirage IVA-04 was essentially representative of the production aircraft that would follow. It took 18 months to build the 01 in Dassault's Saint-Cloud plant near Paris. [51], In July 1984, a contract was formally issued for the upgrade of a total of 18 Mirage IVAs to carry the ASMP missile in the place of traditional bombs; these aircraft were redesignated Mirage IVP (Penetration). [3] The Mirage IV also carried three times more internal fuel than the Mirage III. So, no there was no hesitancy. “We were, in my time, poorly equipped for jamming and countermeasures, there was only the internal system integrated into the aircraft. ", Mirage IV information and photos by Yves Fauconnier, Mirage IV data from former Forces Aériennes Stratégiques website, https://en.wikipedia.org/w/index.php?title=Dassault_Mirage_IV&oldid=980652259, Articles with French-language sources (fr), Articles with unsourced statements from June 2007, Articles with unsourced statements from June 2015, Articles with unsourced statements from November 2010, Articles with unsourced statements from August 2015, Aircraft specs templates using afterburner without dry parameter, Military articles needing translation from French Wikipedia, Creative Commons Attribution-ShareAlike License, 16× 454 kg (1,000 lb) free-fall conventional bombs. I can just see Serge Dassault in the overcoat he never took off after the camps, stroking his chin and saying “…..needs more fin. The IVA I knew had only analogue equipment, needle dials.One regret, especially for a pilot used to the Mirage IIIE: the means of monitoring and controlling navigation were limited. ", "Tangible Mirages: The Most Successful Family of European Aeroplanes. [13] Free-falling munitions could also be aimed using a ventral blister-mounted periscope from the navigator's position. [39], In February 1964 deliveries of the Mirage IV to the French Air Force started, with the first French Mirage IV squadron being declared operational on 1 October that year. “I already had the opportunity to use take-off assistance rockets on the F-84F. Date/time Contributor Updates; 12-Dec-2018 20:49: Cobar: Added : 28-Aug-2020 19:04: TB: Updated [Aircraft type, Total fatalities, Other fatalities, Source, Narrative] The Mirage IV shares design features and a visual resemblance to the Mirage III fighter, featuring a tailless delta wing and a single square-topped vertical fin. Finally in 1996, with the advent of the two-seat Mirage 2000N (N for Nuclear), the Mirage IV no longer served in a nuclear role. [14] While the first Mirage IV prototype was fitted with double-eyelid engine nozzles, production aircraft featured a complicated variable geometry nozzle that automatically varied in response to the descent rate and airspeed. Dassault Mirage III Modeler's Online Reference Cybermodeler Online The aircraft's aerodynamic features were very similar to the III's but required an entirely new structure and layout. The acceleration was therefore very sensitive, but limited by the progressive ignition in three overlapping bursts over a total duration of around 15 to 20 seconds.Designed for wartime, these rockets were used only for training at maximum cleared take-off weight. New York: Charles Scribner's and Sons; 1973. [37] The Mirage IVA could theoretically carry up to six large conventional bombs at the cost of drop tanks and ECM pods; such armament was rarely fitted in practice. “The finesse of its airframe, which allowed for amazing performance, and its aesthetics (as with most planes coming from Dassault, it must be said).It was perfectly suited to the missions for which it was designed: high altitude and high Mach speeds, and later very low altitude, high speed as well as being able to navigate anywhere on the planet completely autonomously. The weapon-related issues were the other. Its engines featured moveable inlet half-cones ("souris / mice") to adjust for different airflow conditions, as well as spring … Cookie Policy Please note that we use cookies to improve your shopping experience. At any one time 12 aircraft would be in the air, with a further 12 on the ground kept at four minutes' readiness and the final 12 at 45 minutes' readiness, each equipped with an onboard functional nuclear weapon. This plane was really revolutionary for a Mirage III pilot.”, Rare, unofficial confrontations with real fighters have shown that it probably would have been a proud fighter, especially with more powerful engines.”. [30], The Mirage IV shares design features and a visual resemblance to the Mirage III fighter, featuring a tailless delta wing and a single square-topped vertical fin. By 1963, the majority of missions involving the Mirage IV were being planned as low-level flights. The Dassault Mirage IV was a strategic bomber developed from experience obtained from the Mirage III fighter. [12] The Mirage IV* was to carry a bombload of up to 9,100 kilograms (20,000 lb). ", This page was last edited on 27 September 2020, at 18:11. The Mirage IV was of a basic delta-wing design with a single rudder at rear. If hostilities broke out, we would only have been a response to limit a potentially stronger attack. As a bonus, I am including another Mirage III model, the IIIB2, with the Mirage IV nose refuelling probe used for training. [3], In order to refuel the Mirage IVA fleet, France purchased 14 (12 plus 2 spares) U.S. Boeing C-135F tankers. [21] The aircraft, known as the Mirage IV* or Mirage IVS (S for Spey) would be re-engined with more powerful Rolls-Royce Spey turbofan engines with a total of 185 kilonewtons (41,700 lbf), larger (fuselage depth increased by 7.6 centimetres (3 in), had an approximately 0.61 metres (2 ft) forward fuselage extension, and was to weigh 36,000 kilograms (80,000 lb)), and use avionics planned for the TSR-2, although BAC preferred the French Antilope radar. [27][29], BAC and Dassault had also hoped to sell the Mirage IV* to France and to export the Mirage IV* to various nations, such as India, possibly Israel, and others; the lack of a British sale put an end to such possibilities. The Dassault Mirage IV was the French answer to the escalating Cold War era and the threat of nuclear attack from the Soviet Block. In addition, it required surprisingly little maintenance considering its age and complexity. Translated by Elodie Rougeot & Owen Dakin, During a low altitude bombing training mission on a seaside range, an engine failure on departure from Solenzara forced me to give the order to abandon the plane while we were at very low altitude over the sea and flying at 600 knots.”. [36], During the 1980s, a total of 18 Mirage IVs were retrofitted with a centreline pylon and associated equipment to carry and launch the nuclear ASMP stand-off missile. “The largest armed warplane in the French air force plane could not be more impressive! [53][54] The conversion of Mirage IVAs to IVPs involved a large number of modifications and re-workings of the aircraft. For many years it was a vital part of the nuclear triad of the Force de Frappe, France's nuclear deterrent striking force. Jean Copponnex refers to the “secretive world” of “Chasse B”. Jackson, Paul. One of my favorite Cold War jets. [51] In 1979, in response to the decreasing effectiveness of free-fall bombs used by both its strategic and tactical nuclear forces, development of the ASMP stand-off missile was initiated; the ASMP would possess a range of up to 400 km (250 mi) and was alternative armed with either a single 150 or 300 kiloton nuclear warhead. [5] It was considerably more advanced than the Mirage III, incorporating new features such as machined and chem-milled planks, tapered sheets, a small amount of titanium, and integral fuel tanks in many locations including the leading portion of the tailfin. Feb 1, 2017 - Images and profiles of the Dassault Mirage IV. The Dassault Mirage IV was a French supersonic strategic bomber and deep-reconnaissance aircraft. On 12 October 1982, the first modernised Mirage IVP performed its first flight; it re-entered active service on 1 May 1986. ( Log Out /  [6][9] Flight 138, on 23 September, corroborated the initial performance and pushed the record on a 500 km closed circuit to an average of 1,972 km/h (1,225 mph), flying between Mach 2.08 and Mach 2.14. The early Mirage IVA had a fuselage recess under the engines which could hold a single AN-11 or AN-22 nuclear weapon of 60 kt yield. Combining hideous lethality with graceful lines, this Cold War warrior served France from 1964-2005. On later aircraft, this equipment typically included a Barax NG jammer pod under the port wing and a BOZ expendables dispenser under the starboard wing. Hi guys, this is my Mirage IV A, from Heller. These machines are very spectacular when seen from outside, but so is the feeling inside the aircraft. "Pénétration Augumentation". [12] By 1962, the second prototype had conducted simulated nuclear bombing runs in the trials range at Colomb-Bechar in southern Algeria. You can really help. [34] In the event of nuclear war between the major powers, it was thought that there would be little point in having the fuel to return as the host air bases would have been destroyed; instead, surviving Mirage IVs would have diverted to land at bases in nearby neutral countries following the delivery of their ordnance. Sud Aviation and Nord Aviation both submitted competing proposals, both based on existing aircraft; Sud Aviation proposed the Super Vautour, a stretched Sud Aviation Vautour with 47 kilonewtons (10,500 lbf) thrust SNECMA Atar engines and a combat radius of 2,700 kilometres (1,700 mi) at Mach 0.9. The first operational use of the system took place during missions in Chad in September 1974. “No fight experienced! In 1963, the Australian government sought a replacement for the Royal Australian Air Force fleet of English Electric Canberra bombers, largely in response to the Indonesian Air Force's purchase of missile-armed Tupolev Tu-16 bombers. This contributed to the pride of all the members of the FAS who participated in the adventure.”. These squadrons were:[41][42], After establishment of its own deterrent force, the Force de Dissuassion, more commonly known as the Force de frappe, France withdrew from the military command structure of NATO in 1966.
