163-539: The Morane-Saulnier M.S.406 is a French fighter aircraft developed and manufactured by Morane-Saulnier starting in 1938. It was France's most numerous fighter during the Second World War and one of only two French designs to exceed 1,000 in number. At the beginning of the war, it was one of only two French-built aircraft capable of 400 km/h (250 mph) – the other being the Potez 630 . In response to
326-408: A biplane , a parasol wing has less bracing and lower drag. It remains a popular configuration for amphibians and small homebuilt and ultralight aircraft . Although the first successful aircraft were biplanes, the first attempts at heavier-than-air flying machines were monoplanes, and many pioneers continued to develop monoplane designs. For example, the first aeroplane to be put into production
489-458: A heat exchanger placed on the port engine exhausts. The cockpit had a modified windscreen to accommodate a new reflector sight arrangement, as well the adoption of electropneumatic controls of the armaments and provisions for the carriage of under-wing auxiliary fuel tanks. Following the completion of a pair of prototypes, during February 1940, the French government issued an order authorising
652-584: A by now mediocre performance. The first Eindecker victory came on 1 July 1915, when Leutnant Kurt Wintgens , of Feldflieger Abteilung 6 on the Western Front, downed a Morane-Saulnier Type L. His was one of five Fokker M.5 K/MG prototypes for the Eindecker , and was armed with a synchronized aviation version of the Parabellum MG14 machine gun. The success of the Eindecker kicked off
815-470: A cadre of exceptional pilots. In the United Kingdom, at the behest of Neville Chamberlain (more famous for his 'peace in our time' speech), the entire British aviation industry was retooled, allowing it to change quickly from fabric covered metal framed biplanes to cantilever stressed skin monoplanes in time for the war with Germany, a process that France attempted to emulate, but too late to counter
978-435: A competitive cycle of improvement among the combatants, both sides striving to build ever more capable single-seat fighters. The Albatros D.I and Sopwith Pup of 1916 set the classic pattern followed by fighters for about twenty years. Most were biplanes and only rarely monoplanes or triplanes . The strong box structure of the biplane provided a rigid wing that allowed the accurate control essential for dogfighting. They had
1141-443: A difficult deflection shot. The first step in finding a real solution was to mount the weapon on the aircraft, but the propeller remained a problem since the best direction to shoot is straight ahead. Numerous solutions were tried. A second crew member behind the pilot could aim and fire a swivel-mounted machine gun at enemy airplanes; however, this limited the area of coverage chiefly to the rear hemisphere, and effective coordination of
1304-448: A dive. Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.9 or 404 cannon with 60 rounds in the V of the engine, fired through the propeller hub and two 7.5 mm (0.295 in) MAC 1934 machine guns (one in each wing, each with 300 rounds). A weakness of the MAC 1934 was its operation at high altitudes. It was found that at altitudes over 6,000 m (20,000 ft),
1467-552: A form that would replace all others in the 1930s. As collective combat experience grew, the more successful pilots such as Oswald Boelcke , Max Immelmann , and Edward Mannock developed innovative tactical formations and maneuvers to enhance their air units' combat effectiveness. Allied and – before 1918 – German pilots of World War I were not equipped with parachutes , so in-flight fires or structural failures were often fatal. Parachutes were well-developed by 1918 having previously been used by balloonists, and were adopted by
1630-465: A further 74 examples, which were all delivered by 29 August 1940. In 1942, a further two were assembled with spares originally set aside for the original production run. During 1944, surviving aircraft were modified with new cooling and hydraulic installations, and were fitted with ejector exhausts. These modifications were the same standard as the D-3801 series, making them identical with the exception of
1793-664: A great deal of ground-attack work. In World War II, the USAAF and RAF often favored fighters over dedicated light bombers or dive bombers , and types such as the Republic P-47 Thunderbolt and Hawker Hurricane that were no longer competitive as aerial combat fighters were relegated to ground attack. Several aircraft, such as the F-111 and F-117, have received fighter designations though they had no fighter capability due to political or other reasons. The F-111B variant

Manufacturing of the M.S.406 was wound down during March 1940, by which point the original order for 1,000 fighters had been delivered in full to the French Air Force, along with a further 77 aircraft which had been constructed for foreign users (30 fighters for Finland and 45 for Turkey ). Additional M.S.406 orders that had been placed for Lithuania and Poland were cancelled with
2119-400: A large production order was attached, was French aircraft manufacturer Morane-Saulnier . The company's design team quickly projected that a low-wing monoplane design would be capable of delivering the desired level of performance; other features were to include an enclosed cockpit, a variable-pitch propeller and landing flaps . It was decided to submit their own response to the requirement,
2282-570: A license for local production of the MS.406. Two MS.406H fighters were supplied to Switzerland in September 1938 and April 1939 to serve as pattern aircraft as the D-3800 , retaining the earlier wing design of the 405, but powered by the newer Hispano-Suiza 12Y-31 engines as used by the MS.406. Pre-production started with a run of eight aircraft from EKW with engines built by Adolph Saurer AG driving
2445-544: A low-wing, shoulder-wing and high-wing configurations give increased propeller clearance on multi-engined aircraft. On a large aircraft, there is little practical difference between a shoulder wing and a high wing; but on a light aircraft, the configuration is significant because it offers superior visibility to the pilot. On light aircraft, shoulder-wings tend to be mounted further aft than a high wing, and so may need to be swept forward to maintain correct center of gravity . Examples of light aircraft with shoulder wings include
2608-471: A new Escher-Wyss EW-V3 fully adjustable propeller. Instruments were replaced with Swiss versions and the drum-fed MAC machine guns with locally designed and built belt-fed guns, eliminating the wing-bulges of the French version, and avoiding the freezing problems encountered by French guns. The first of these aircraft was completed in November 1939. The pre-production models were then followed with an order for
2771-431: A number of twin-engine fighters were built; however they were found to be outmatched against single-engine fighters and were relegated to other tasks, such as night fighters equipped with radar sets. By the end of the war, turbojet engines were replacing piston engines as the means of propulsion, further increasing aircraft speed. Since the weight of the turbojet engine was far less than a piston engine, having two engines
2934-550: A part of military nomenclature, a letter is often assigned to various types of aircraft to indicate their use, along with a number to indicate the specific aircraft. The letters used to designate a fighter differ in various countries. In the English-speaking world, "F" is often now used to indicate a fighter (e.g. Lockheed Martin F-35 Lightning II or Supermarine Spitfire F.22 ), though "P" used to be used in
3097-441: A pylon. Additional bracing may be provided by struts or wires extending from the fuselage sides. The first parasol monoplanes were adaptations of shoulder wing monoplanes, since raising a shoulder mounted wing above the fuselage greatly improved visibility downwards, which was useful for reconnaissance roles, as with the widely used Morane-Saulnier L . The parasol wing allows for an efficient design with good pilot visibility, and
3260-638: A range of specialized aircraft types. Some of the most expensive fighters such as the US Grumman F-14 Tomcat , McDonnell Douglas F-15 Eagle , Lockheed Martin F-22 Raptor and Russian Sukhoi Su-27 were employed as all-weather interceptors as well as air superiority fighter aircraft, while commonly developing air-to-ground roles late in their careers. An interceptor is generally an aircraft intended to target (or intercept) bombers and so often trades maneuverability for climb rate. As
3423-412: A requirement for a fighter issued by the French Air Force in 1934, Morane-Saulnier built a prototype, designated MS.405 , of mixed materials. This had the distinction of being the company's first low-wing monoplane, as well as the first to feature an enclosed cockpit, and the first design with a retracting undercarriage . The entry to service of the M.S.406 to the French Air Force in early 1939 represented

#17327871143823586-742: A result, during the early months of these campaigns, Axis air forces destroyed large numbers of Red Air Force aircraft on the ground and in one-sided dogfights. In the later stages on the Eastern Front, Soviet training and leadership improved, as did their equipment. By 1942 Soviet designs such as the Yakovlev Yak-9 and Lavochkin La-5 had performance comparable to the German Bf 109 and Focke-Wulf Fw 190 . Also, significant numbers of British, and later U.S., fighter aircraft were supplied to aid
3749-518: A second assembly line was established at the nationalized factories of SNCAO at St. Nazaire in order to produce the type. In April 1937, an initial order for 50 SNCAO-built M.S.406 fighters was placed; in August 1937, a follow-up order for 80 aircraft was issued. In April 1938, as a component of the French Air Force's Plan V , a large order for 825 M.S.406 was placed with the various nationalised French aircraft industries. During late 1938, production of
3912-643: A separate (and vulnerable) radiator, but had increased drag. Inline engines often had a better power-to-weight ratio . Some air forces experimented with " heavy fighters " (called "destroyers" by the Germans). These were larger, usually twin-engined aircraft, sometimes adaptations of light or medium bomber types. Such designs typically had greater internal fuel capacity (thus longer range) and heavier armament than their single-engine counterparts. In combat, they proved vulnerable to more agile single-engine fighters. The primary driver of fighter innovation, right up to
4075-617: A single aircraft delivered in 1943. The engine problems were eventually resolved in 1944. With 790.4 kW (1,060 hp) from the Hispano-Suiza 12Y-51, the speed was boosted to 534 km/h (332 mph), roughly equivalent to the D.520 or the Hurricane. Weights were between 2,124–2,725 kg (4,683–6,008 lb). After being retired from operational use as a fighter when the North American P-51 Mustang
4238-420: A single operator, who flew the aircraft and also controlled its armament. They were armed with one or two Maxim or Vickers machine guns, which were easier to synchronize than other types, firing through the propeller arc. Gun breeches were in front of the pilot, with obvious implications in case of accidents, but jams could be cleared in flight, while aiming was simplified. The use of metal aircraft structures
4401-544: A thin sheet of duralumin bonded to a thicker sheet of plywood . Morane-Saulnier had a long history of producing warplanes dating back to the pre- First World War years but in the inter-war period, they had concentrated on civil designs. The aircraft was a departure for them, being their first low-wing monoplane, first with an enclosed cockpit and first with retracting landing gear. Prior to this, their most modern designs were fixed-gear parasol monoplanes . The new 641.3 kW (860 hp) Hispano-Suiza 12Ygrs engine driving

The M.S.405 was a low-wing monoplane of mixed construction, being furnished with a fabric-covered wooden tail and a bonded metal/wood material ( Plymax ) skin fixed to duralumin tubing. Plymax consisted of a thin sheet of duralumin bonded to a thicker sheet of plywood. It was
4727-467: A two-pitch Chauvière propeller powered the first M.S405-1 prototype, which flew on 8 August 1935. First flown by French aerobatic pilot Michel Détroyat , the prototype demonstrated the type's favourable flying characteristics from the onset. Early test flights were flown with a fixed undercarriage, which was replaced by a retractable counterpart later on. After 80 hours of test flights, in January 1936,
4890-467: Is a configuration whereby the wing is mounted near the top of the fuselage but not on the very top. It is so called because it sits on the "shoulder" of the fuselage, rather than on the pilot's shoulder. Shoulder-wings and high-wings share some characteristics, namely: they support a pendulous fuselage which requires no wing dihedral for stability; and, by comparison with a low-wing, a shoulder-wing's limited ground effect reduces float on landing. Compared to
5053-402: Is a fast, heavily armed and long-range type, able to act as an escort fighter protecting bombers , to carry out offensive sorties of its own as a penetration fighter and maintain standing patrols at significant distance from its home base. Bombers are vulnerable due to their low speed, large size and poor maneuvrability. The escort fighter was developed during World War II to come between

The word "fighter" was first used to describe a two-seat aircraft carrying a machine gun (mounted on a pedestal) and its operator as well as the pilot . Although the term was coined in the United Kingdom, the first examples were the French Voisin pushers beginning in 1910, and a Voisin III would be the first to shoot down another aircraft, on 5 October 1914. However at

Recognized classes of fighter include: Of these, the Fighter-bomber , reconnaissance fighter and strike fighter classes are dual-role, possessing qualities of the fighter alongside some other battlefield role. Some fighter designs may be developed in variants performing other roles entirely, such as ground attack or unarmed reconnaissance . This may be for political or national security reasons, for advertising purposes, or other reasons. The Sopwith Camel and other "fighting scouts" of World War I performed
5542-644: The ARV Super2 , the Bölkow Junior , Saab Safari and the Barber Snark . A high wing has its upper surface on or above the top of the fuselage. It shares many advantages and disadvantages with the shoulder wing, but on a light aircraft, the high wing has poorer upwards visibility. On light aircraft such as the Cessna 152 , the wing is usually located above the cabin, so that the wing spar passes over

Both Switzerland and Turkey also operated the type; the Swiss actually downed a number of both German and Allied aircraft during the 1944–45 period. Before the Pacific campaign proper, Vichy authorities in French Indochina were engaged in a frontier war against Thailand , during 1940–41. A number of M.S.406s stationed in Indochina downed several Thai fighters before all French Air Force units were withdrawn from

The unit lost 15 aircraft. Total Finnish kills in Moranes were 121. The top Morane ace in all theatres was W/O Urho Lehtovaara , with 15 of his 44.5 total kills achieved in Moranes. The Finnish nicknames were Murjaani (" moor " or "Negro"),

The Luftwaffe operated a number of the type for training purposes, while others were sold off to third parties. Finland purchased additional M.S.406s (as well as a few 406/410 hybrids) from the Germans, while others were passed off to Italy and some 48 aircraft were delivered to

The French and the Germans didn't have an equivalent as they used two seaters for reconnaissance, such as the Morane-Saulnier L , but would later modify pre-war racing aircraft into armed single seaters. It was quickly found that these were of little use since the pilot couldn't record what he saw while also flying, while military leaders usually ignored what

Advanced monoplane fighter-aircraft designs were mass-produced for military services around
7824-462: The cantilever wing, which carries all structural forces internally. However, to fly at practical speeds the wing must be made thin, which requires a heavy structure to make it strong and stiff enough. External bracing can be used to improve structural efficiency, reducing weight and cost. For a wing of a given size, the weight reduction allows it to fly slower and with a lower-powered and more economical engine. For this reason, all monoplane wings in

The German military Idflieg aircraft designation system prior to 1918 prefixed monoplane type designations with an E , until the approval of the Fokker D.VIII fighter from its former "E.V" designation. However, the success of the Fokker was short-lived, and World War I was dominated by biplanes. Towards the end of the war, the parasol monoplane became popular and successful designs were produced into

The added thrust boosted the top speed to 509 km/h (316 mph; 275 kn) at 4,000 m (13,000 ft), resulting in an improvement of about 40 km/h (25 mph; 22 kn) over the M.S.406 at the same height. Production of the M.S.410 had only just started in May 1940, when
11410-442: The M.S.406, such as the Finnish Mörkö-Morane ). By the end of the war, the majority of M.S.406s and its derivatives were out of service, having been rendered obsolete by rapid advances in fighter aircraft technology. Its final use was as an advanced trainer aircraft in Finland, prior to the last examples of the type being scrapped during 1952. During 1934, the Service Technique de l'Aéronautique (Aeronautical Technical Service) of
11573-550: The Morane - the 406 was usually outclassed by the Luftwaffe fighters. The story of GC III/7 was tragically typical. On 15 May, nine Moranes of this fighter unit encountered a dozen Bf 109s over Mézières. The Messerschmitts stayed a few thousand feet above their French opponents and dived in pairs to attack, with a single firing pass, before climbing back and then repeating the attack. Three M.S.406 went spinning down in flames and only one pilot bailed out, severely wounded. A fourth Morane, riddled with bullets, crash-landed at Soissons and
11736-647: The Phoney War, a total of 10,119 fighter missions were reportedly flown over the Army Zones on the border, around half of which being flown by M.S.406 fighters. During the Phoney War, isolated skirmishes occurred between the M.S.406 and fighters of the Luftwaffe , particularly early models of the Messerschmitt Bf 109 . For 32 claimed 'kills' and 16 'probables' achieved by M.S.406s, including against
11899-555: The Soviet Polikarpov I-16 . The later German design was earlier in its design cycle, and had more room for development and the lessons learned led to greatly improved models in World War II. The Russians failed to keep up and despite newer models coming into service, I-16s remaining the most common Soviet front-line fighter into 1942 despite being outclassed by the improved Bf 109s in World War II. For their part,
12062-598: The Soviet war effort as part of Lend-Lease , with the Bell P-39 Airacobra proving particularly effective in the lower-altitude combat typical of the Eastern Front. The Soviets were also helped indirectly by the American and British bombing campaigns, which forced the Luftwaffe to shift many of its fighters away from the Eastern Front in defense against these raids. The Soviets increasingly were able to challenge
12225-552: The US for pursuit (e.g. Curtiss P-40 Warhawk ), a translation of the French "C" ( Dewoitine D.520 C.1 ) for Chasseur while in Russia "I" was used for Istrebitel , or exterminator ( Polikarpov I-16 ). As fighter types have proliferated, the air superiority fighter emerged as a specific role at the pinnacle of speed, maneuverability, and air-to-air weapon systems – able to hold its own against all other fighters and establish its dominance in
12388-529: The United States, Russia, India and China. The first step was to find ways to reduce the aircraft's reflectivity to radar waves by burying the engines, eliminating sharp corners and diverting any reflections away from the radar sets of opposing forces. Various materials were found to absorb the energy from radar waves, and were incorporated into special finishes that have since found widespread application. Composite structures have become widespread, including major structural components, and have helped to counterbalance
12551-497: The ability to gather information by reconnaissance over the battlefield. Early fighters were very small and lightly armed by later standards, and most were biplanes built with a wooden frame covered with fabric, and a maximum airspeed of about 100 mph (160 km/h). A successful German biplane, the Albatross, however, was built with a plywood shell, rather than fabric, which created a stronger, faster airplane. As control of
12714-635: The advantages of fighting above Britain's home territory allowed the RAF to deny Germany air superiority, saving the UK from possible German invasion and dealing the Axis a major defeat early in the Second World War. On the Eastern Front , Soviet fighter forces were overwhelmed during the opening phases of Operation Barbarossa . This was a result of the tactical surprise at the outset of the campaign,
12877-534: The airspace over armies became increasingly important, all of the major powers developed fighters to support their military operations. Between the wars, wood was largely replaced in part or whole by metal tubing, and finally aluminum stressed skin structures (monocoque) began to predominate. By World War II , most fighters were all-metal monoplanes armed with batteries of machine guns or cannons and some were capable of speeds approaching 400 mph (640 km/h). Most fighters up to this point had one engine, but
13040-502: The basis for an effective "fighter" in the modern sense of the word. It was based on small fast aircraft developed before the war for air racing such with the Gordon Bennett Cup and Schneider Trophy . The military scout airplane was not expected to carry serious armament, but rather to rely on speed to "scout" a location, and return quickly to report, making it a flying horse. British scout aircraft, in this sense, included
13203-414: The bombers and enemy attackers as a protective shield. The primary requirement was for long range, with several heavy fighters given the role. However they too proved unwieldy and vulnerable, so as the war progressed techniques such as drop tanks were developed to extend the range of more nimble conventional fighters. The penetration fighter is typically also fitted for the ground-attack role, and so
13366-503: The bulk upgrading of 500 M.S.406 fighters to the better armed, stronger and faster (509 km/h (316 mph) M.S.410 configuration. It took 15 days to convert each fighter but conversions were stopped in May 1940 to put every available combat aircraft into action during the Battle of France against invading German forces. Only five complete production M.S.410 aircraft, along with 150 pairs of
13529-488: The company's first low-wing monoplane design, as well as the first with an enclosed cockpit, and the first to feature retractable landing gear. The new 641.3 kW (860 hp) Hispano-Suiza 12Ygrs engine driving a two-pitch Chauvière propeller powered the first prototype, M.S.405-01 , which flew on 8 August 1935. The second prototype, M.S.405-02 , powered by a 671.1 kW (900 hp) Hispano-Suiza 12Ycrs engine, performed its first flight on 20 January 1937. Outfitted with
13692-610: The defense budgets of modern armed forces. The global combat aircraft market was worth $ 45.75 billion in 2017 and is projected by Frost & Sullivan at $ 47.2 billion in 2026: 35% modernization programs and 65% aircraft purchases, dominated by the Lockheed Martin F-35 with 3,000 deliveries over 20 years. A fighter aircraft is primarily designed for air-to-air combat . A given type may be designed for specific combat conditions, and in some cases for additional roles such as air-to-ground fighting. Historically
13855-550: The design approach of the Italians and Japanese made their fighters ill-suited as interceptors or attack aircraft. During the invasion of Poland and the Battle of France , Luftwaffe fighters—primarily the Messerschmitt Bf 109 —held air superiority, and the Luftwaffe played a major role in German victories in these campaigns. During the Battle of Britain , however, British Hurricanes and Spitfires proved roughly equal to Luftwaffe fighters. Additionally Britain's radar-based Dowding system directing fighters onto German attacks and
14018-522: The early 1960s since both were believed unusable at the speeds being attained, however the Vietnam War showed that guns still had a role to play, and most fighters built since then are fitted with cannon (typically between 20 and 30 mm (0.79 and 1.18 in) in caliber) in addition to missiles. Most modern combat aircraft can carry at least a pair of air-to-air missiles. In the 1970s, turbofans replaced turbojets, improving fuel economy enough that
14181-413: The end of the First World War, the inherent high drag of the biplane was beginning to restrict performance. Engines were not yet powerful enough to make the heavy cantilever-wing monoplane viable, and the braced parasol wing became popular on fighter aircraft, although few arrived in time to see combat. It remained popular throughout the 1920s. On flying boats with a shallow hull, a parasol wing allows
14344-408: The end of the Phoney War on 10 May 1940, the month in which a massive full-scale invasion by German forces of mainland France commenced, resulting in the Battle of France. On the eve of the invasion, a total of 10 Groupes de Chasse were equipped with M.S.406 fighters, along with a number of defensive units which were almost exclusively equipped with either the M.S.406 or Bloch MB.152 aircraft. During
14507-459: The engine installation. At the end of the war the remaining aircraft were used as trainers, until the last one was scrapped in 1954. The Swiss continued development of the MS.412 when French involvement stopped following the June 1940 Armistice . The Dornier-Altenrhein factory completed a prototype powered with a licensed-produced HS-51 12Y engine, generating 790.4 kW (1,060 hp) together with
14670-487: The engines to be mounted above the spray from the water when taking off and landing. This arrangement was popular on flying boats during the 1930s; a late example being the Consolidated PBY Catalina . It died out when taller hulls became the norm during World War II, allowing a high wing to be attached directly to the hull. As ever-increasing engine powers made the weight of all-metal construction and
14833-507: The excellent 20 mm (0.787 in) MG 151/20 cannon in the engine mounting. However, supplies of the MG 151 were limited, and several received captured 12.7 mm (0.500 in) Berezin UB S guns instead. The first example of the modified fighter, MS-631, made its first flight on 25 January 1943, and the results were startling: the aircraft was 64 km/h (40 mph; 35 kn) faster than
14996-513: The fighter. Rifle-caliber .30 and .303 in (7.62 and 7.70 mm) calibre guns remained the norm, with larger weapons either being too heavy and cumbersome or deemed unnecessary against such lightly built aircraft. It was not considered unreasonable to use World War I-style armament to counter enemy fighters as there was insufficient air-to-air combat during most of the period to disprove this notion. The rotary engine , popular during World War I, quickly disappeared, its development having reached
15159-491: The first major export customer was Switzerland who, in September 1938, acquired a manufacturing licence for the type to be manufactured by Swiss firm Fabrique fédérale d'avions in Emmen . During May 1938, the 2nd Escadrille of the 7th Groupe de Chasse at Reims conducted operational testing of the type using a handful of pre-production M.S.406 aircraft. In spite of some accidents experienced, pilots were commonly pleased with
15322-419: The first modern fighter aircraft to be adopted by the service. Although a sturdy and highly manoeuvrable fighter aircraft, it was considered underpowered and weakly armed when compared to its contemporaries and the M.S.406 was outperformed by the Messerschmitt Bf 109 E during the Battle of France . The type was capable of holding its own during the so-called Phoney War from September 1939 to 10 May 1940. Upon
15485-661: The fixed radiator and revised exhausts as tested on the MS.411, in October 1940. The new type retained the armament changes and other improvements introduced on the D.3800. This series was put into production in 1941 as the D-3801 with continued deliveries until 1945 with 207 completed. Another 17 were built from spares between 1947 and 1948. Reliability of the new engine was at first extremely poor, with problems with crankshaft bearings causing several accidents. The engine problems slowed deliveries, with only 16 aircraft produced in 1942 and
15648-419: The ground to prevent their capture. The decision to employ small groups of French fighters against larger German formations was mostly ineffective against bombers and often costly. In combat against enemy fighters, the M.S.406 often experienced mixed results. While there were isolated incidents of favourable results being achieved with the type even against the capable Bf 109 - which was 100 km/h faster than
15811-519: The guns had a tendency to freeze. Heaters were added to the guns for high-altitude use. Beyond the base M.S.406 design, the development of improved variants and derivatives were emphasised even as mass production of the type was still being established. Perhaps the most significant of these was the M.S.410 , which was developed on the basis of very early combat experience gathered during autumn 1939. This model had four MAC 1934 machine guns with 550 rounds per gun, all of which were heated by warm air fed via
15974-406: The guns were subjected). Shooting with this traditional arrangement was also easier because the guns shot directly ahead in the direction of the aircraft's flight, up to the limit of the guns range; unlike wing-mounted guns which to be effective required to be harmonised , that is, preset to shoot at an angle by ground crews so that their bullets would converge on a target area a set distance ahead of
16137-406: The highest efficiency and lowest drag of any wing configuration and is the simplest to build. However, during the early years of flight, these advantages were offset by its greater weight and lower manoeuvrability, making it relatively rare until the 1930s. Since then, the monoplane has been the most common form for a fixed-wing aircraft. The inherent efficiency of the monoplane is best achieved in
16300-433: The innovations was the development of the " finger-four " formation by the German pilot Werner Mölders . Each fighter squadron (German: Staffel ) was divided into several flights ( Schwärme ) of four aircraft. Each Schwarm was divided into two Rotten , which was a pair of aircraft. Each Rotte was composed of a leader and a wingman. This flexible formation allowed the pilots to maintain greater situational awareness, and
16463-514: The interceptor. The equipment necessary for daytime flight is inadequate when flying at night or in poor visibility. The night fighter was developed during World War I with additional equipment to aid the pilot in flying straight, navigating and finding the target. From modified variants of the Royal Aircraft Factory B.E.2c in 1915, the night fighter has evolved into the highly capable all-weather fighter. The strategic fighter
16626-476: The invasion of France in May 1940, approximately 400 Moranes were lost. Out of these, around 150 were lost to enemy fighters and ground fire, while another 100 aircraft were destroyed on the ground during enemy air raids; the remainder were deliberately destroyed by French military personnel to prevent the fighters from falling into German hands. French M.S.406 squadrons had achieved 191 confirmed victories, along with another 83 probable victories. Limited production of
16789-420: The lack of rear-view mirrors. While the aircraft was very manoeuvrable and could withstand high amounts of battle damage, potentially giving possible advantages during combat against Luftwaffe fighters, the M.S.406 was overall outclassed by the Bf 109. Efforts to replace the M.S.406 (by, for example, converting existing aircraft to the improved M.S.410 standard) with a more capable fighter failed to occur prior to
16952-420: The last piston engine support aircraft could be replaced with jets, making multi-role combat aircraft possible. Honeycomb structures began to replace milled structures, and the first composite components began to appear on components subjected to little stress. With the steady improvements in computers, defensive systems have become increasingly efficient. To counter this, stealth technologies have been pursued by
17115-584: The leadership vacuum within the Soviet military left by the Great Purge , and the general inferiority of Soviet designs at the time, such as the obsolescent Polikarpov I-15 biplane and the I-16 . More modern Soviet designs, including the Mikoyan-Gurevich MiG-3 , LaGG-3 and Yakolev Yak-1 , had not yet arrived in numbers and in any case were still inferior to the Messerschmitt Bf 109 . As
17278-427: The low-wing position is its significant ground effect , giving the plane a tendency to float farther before landing. Conversely, this ground effect permits shorter takeoffs. A mid wing is mounted midway up the fuselage. The carry-through spar structure can reduce the useful fuselage volume near its centre of gravity, where space is often in most demand. A shoulder wing (a category between high-wing and mid-wing)
17441-554: The main distinction between types of monoplane is where the wing is mounted vertically on the fuselage . A low wing is one which is located on or near the bottom of the fuselage. Placing the wing low allows good visibility upwards and frees the central fuselage from the wing spar carry-through. By reducing pendulum stability, it makes the aircraft more manoeuvrable, as on the Spitfire ; but aircraft that value stability over manoeuvrability may then need some dihedral . A feature of
17604-509: The manufacturing programme. By April 1939, the production lines were delivering six aircraft per day and when war broke out on 3 September 1939, the rate production had risen to 11 aircraft per day; at this time, 535 M.S.406s had entered squadron service. According to aviation author Gaston Botquin, the rate of production of the type was comparable to the initial model of the British Hawker Hurricane . Production had reached
17767-410: The mid-1930s, the majority of fighters in the US, the UK, Italy and Russia remained fabric-covered biplanes. Fighter armament eventually began to be mounted inside the wings, outside the arc of the propeller, though most designs retained two synchronized machine guns directly ahead of the pilot, where they were more accurate (that being the strongest part of the structure, reducing the vibration to which
17930-495: The most modern weapons, against an enemy in complete command of the air, fights like a savage…" Throughout the war, fighters performed their conventional role in establishing air superiority through combat with other fighters and through bomber interception, and also often performed roles such as tactical air support and reconnaissance . Fighter design varied widely among combatants. The Japanese and Italians favored lightly armed and armored but highly maneuverable designs such as
18093-507: The new M.S.406 was over 8 km/h (5 mph; 4 kn) faster than the M.S. 405, at 489 km/h (304 mph; 264 kn), tested with no problem to reach up to 730 km/h (454 mph; 394 kn) in a dive. Armament consisted of a 20 mm (0.787 in) Hispano-Suiza HS.9 or Hispano-Suiza HS.404 cannon with 60 rounds in the V of the engine and fired through the propeller hub, and two 7.5 mm (0.295 in) MAC 1934 machine guns (one in each wing, each with 300 rounds). While
18256-409: The new engine, the fighter was able to attain a speed of 443 km/h (275 mph; 239 kn). The M.S.406 designation was adopted following various design changes from the earlier M.S.405 prototypes; two of the principal design changes were the inclusion of a new weight-saving wing structure and the new retractable radiator. Powered by the production 641.3 kW (860 hp) HS 12Y-31 engine,
18419-447: The occupants' heads, leaving the wing in the ideal fore-aft position. An advantage of the high-wing configuration is that the fuselage is closer to the ground which eases cargo loading, especially for aircraft with a rear-fuselage cargo door. Military cargo aircraft are predominantly high-wing designs with a rear cargo door. A parasol wing is not directly attached to the fuselage but held above it, supported by either cabane struts or
18582-607: The opposition. Subsequently, radar capabilities grew enormously and are now the primary method of target acquisition . Wings were made thinner and swept back to reduce transonic drag, which required new manufacturing methods to obtain sufficient strength. Skins were no longer sheet metal riveted to a structure, but milled from large slabs of alloy. The sound barrier was broken, and after a few false starts due to required changes in controls, speeds quickly reached Mach 2, past which aircraft cannot maneuver sufficiently to avoid attack. Air-to-air missiles largely replaced guns and rockets in
18745-528: The original French version, and the service ceiling was increased from 10,000 m (33,000 ft) to 12,000 m (39,000 ft). Originally, it was planned to convert all the 41 remaining M.S.406s and M.S.410s with the Soviet engine, but it took time, and the first front-line aircraft of this type did not reach LeLv 28 until July/August 1944. By the end of the Continuation War in September 1944, only three examples had been converted (including
18908-604: The original prototype). Lieutenant Lars Hattinen (an ace with six victories) scored three kills with the Mörkö-Morane, one with each Mörkö-Morane in the squadron. More fighters arrived from the factory, though, and the Mörkö-Moranes took part in the Lapland War as reconnaissance and ground attack aircraft. Not all the Mörkö-Morane conversions were completed before March 1945, when the entire re-engining programme
19071-488: The outbreak of World War I , front-line aircraft were mostly unarmed and used almost exclusively for reconnaissance . On 15 August 1914, Miodrag Tomić encountered an enemy airplane while on a reconnaissance flight over Austria-Hungary which fired at his aircraft with a revolver, so Tomić fired back. It was believed to be the first exchange of fire between aircraft. Within weeks, all Serbian and Austro-Hungarian aircraft were armed. Another type of military aircraft formed
19234-493: The outbreak of the war. According to Botquin, the M.S.406 had attracted considerable foreign attention during the late 1930s, and had shown signs of commercial promise early on. During 1937, negotiations were underway between France and Belgium to undertake the licensed production of the type by Belgian aircraft manufacturer Avions Fairey for both the Belgian and French air forces, but these ultimately came to nothing. Instead,
19397-451: The outset for dual roles. Other fighter designs are highly specialized while still filling the main air superiority role, and these include the interceptor and, historically, the heavy fighter and night fighter . Since World War I, achieving and maintaining air superiority has been considered essential for victory in conventional warfare . Fighters continued to be developed throughout World War I, to deny enemy aircraft and dirigibles
19560-487: The period of rapid re-armament in the late 1930s, were not military budgets, but civilian aircraft racing. Aircraft designed for these races introduced innovations like streamlining and more powerful engines that would find their way into the fighters of World War II. The most significant of these was the Schneider Trophy races, where competition grew so fierce, only national governments could afford to enter. At
19723-433: The period, going from a typical 180 hp (130 kW) in the 900 kg (2,000 lb) Fokker D.VII of 1918 to 900 hp (670 kW) in the 2,500 kg (5,500 lb) Curtiss P-36 of 1936. The debate between the sleek in-line engines versus the more reliable radial models continued, with naval air forces preferring the radial engines, and land-based forces often choosing inlines. Radial designs did not require
19886-456: The pilot's maneuvering with the gunner's aiming was difficult. This option was chiefly employed as a defensive measure on two-seater reconnaissance aircraft from 1915 on. Both the SPAD S.A and the Royal Aircraft Factory B.E.9 added a second crewman ahead of the engine in a pod but this was both hazardous to the second crewman and limited performance. The Sopwith L.R.T.Tr. similarly added a pod on
20049-451: The pilots reported. Attempts were made with handheld weapons such as pistols and rifles and even light machine guns, but these were ineffective and cumbersome. The next advance came with the fixed forward-firing machine gun, so that the pilot pointed the entire aircraft at the target and fired the gun, instead of relying on a second gunner. Roland Garros bolted metal deflector plates to the propeller so that it would not shoot itself out of
20212-416: The pioneer era were braced and most were up until the early 1930s. However, the exposed struts or wires create additional drag, lowering aerodynamic efficiency and reducing the maximum speed. High-speed and long-range designs tend to be pure cantilevers, while low-speed short-range types are often given bracing. Besides the general variations in wing configuration such as tail position and use of bracing,
20375-410: The point where rotational forces prevented more fuel and air from being delivered to the cylinders, which limited horsepower. They were replaced chiefly by the stationary radial engine though major advances led to inline engines gaining ground with several exceptional engines—including the 1,145 cu in (18,760 cm ) V-12 Curtiss D-12 . Aircraft engines increased in power several-fold over
20538-412: The pre-production aircraft, the name M.S.406 was adopted for the type. On 3 February 1938, the first pre-production aircraft made its first flight; during December 1938, the final pre-production M.S.406 was delivered. The pre-production aircraft served to build up experience of manufacturing and testing of the type in advance of production M.S.406s. These 15 aircraft were used for various purposes, such as
20701-524: The pre-production aircraft. The two main changes of the M.S. 406 were the inclusion of a new wing structure which saved weight and the fitting of a retractable radiator , underneath the fuselage. Powered by the production 641.3 kW (860 hp) HS 12Y-31 engine, the new design was over 8 km/h (5 mph) faster than the earlier M.S.405 model. Designed to reach speeds of 489 km/h (304 mph), examples were tested without encountering any difficulty in reaching up to 730 km/h (454 mph) in
20864-575: The propeller arc was evident even before the outbreak of war and inventors in both France and Germany devised mechanisms that could time the firing of the individual rounds to avoid hitting the propeller blades. Franz Schneider , a Swiss engineer, had patented such a device in Germany in 1913, but his original work was not followed up. French aircraft designer Raymond Saulnier patented a practical device in April 1914, but trials were unsuccessful because of
21027-461: The propeller arc. Wing guns were tried but the unreliable weapons available required frequent clearing of jammed rounds and misfires and remained impractical until after the war. Mounting the machine gun over the top wing worked well and was used long after the ideal solution was found. The Nieuport 11 of 1916 used this system with considerable success, however, this placement made aiming and reloading difficult but would continue to be used throughout
21190-458: The propeller blades were fitted with metal wedges to protect them from ricochets . Garros' modified monoplane first flew in March 1915 and he began combat operations soon after. Garros scored three victories in three weeks before he himself was downed on 18 April and his airplane, along with its synchronization gear and propeller was captured by the Germans. Meanwhile, the synchronization gear (called
21353-426: The propensity of the machine gun employed to hang fire due to unreliable ammunition. In December 1914, French aviator Roland Garros asked Saulnier to install his synchronization gear on Garros' Morane-Saulnier Type L parasol monoplane . Unfortunately the gas-operated Hotchkiss machine gun he was provided had an erratic rate of fire and it was impossible to synchronize it with the propeller. As an interim measure,
21516-546: The prototype was delivered with all military equipment fitted to CEMA at Villacoublay to participate in service trials. On 19 June 1937, the first prototype generated substantial publicity when Détroyat flew it from Paris to Brussels in Belgium , to be displayed at the Brussels Aeronautical Exhibition . Development of the M.S.405 proceeded fairly slowly; testing revealed the need to modify
21679-611: The relentless fighting that followed, Allied forces suffered a high rate of attrition and were unable to keep up with the level of damage being sustained. Of the M.S.406s that saw action against the Germans, heavy losses were incurred; reportedly, 150 aircraft were lost in action while a further 250–300 fighters were recorded as having been lost through other causes. The rapid advance of German forces led to repeated retreats and abandonment of bases, rendering most repair and replacement efforts disorganized, along with ground crews often having to destroy large numbers of their own fighter aircraft on
21842-409: The revised wings, had been completed by this point. During the late 1930s, there was a growing perception that a major conflict between Germany and France was not only looming but increasingly unavoidable. As part of its rearmament, the French Air Force placed an order for 1,000 M.S406 airframes during March 1938. Morane-Saulnier was unable to produce anywhere near this number at their own factory, thus
22005-421: The role of fighter aircraft is to establish air superiority of the battlespace . Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets, and helps prevent the enemy from doing the same. The key performance features of a fighter include not only its firepower but also its high speed and maneuverability relative to
22168-566: The sizable ground elements of the French Army from the air. During the Phoney War opening phase of the Second World War, a time of relatively low combat intensity, the type's activities focused upon air defence operations with the aim of countering the prolific aerial reconnaissance and probing activities of small groups of Axis -aligned fighters coming over the border, in addition to escorting friendly reconnaissance aircraft. Throughout
22331-532: The skies above the battlefield. The interceptor is a fighter designed specifically to intercept and engage approaching enemy aircraft. There are two general classes of interceptor: relatively lightweight aircraft in the point-defence role, built for fast reaction, high performance and with a short range, and heavier aircraft with more comprehensive avionics and designed to fly at night or in all weathers and to operate over longer ranges . Originating during World War I, by 1929 this class of fighters had become known as
22494-417: The sky and a number of Morane-Saulnier Ns were modified. The technique proved effective, however the deflected bullets were still highly dangerous. Soon after the commencement of the war, pilots armed themselves with pistols, carbines , grenades , and an assortment of improvised weapons. Many of these proved ineffective as the pilot had to fly his airplane while attempting to aim a handheld weapon and make
22657-408: The steady increases in aircraft weight—most modern fighters are larger and heavier than World War II medium bombers. Because of the importance of air superiority, since the early days of aerial combat armed forces have constantly competed to develop technologically superior fighters and to deploy these fighters in greater numbers, and fielding a viable fighter fleet consumes a substantial proportion of
22820-420: The target aircraft. The success or failure of a combatant's efforts to gain air superiority hinges on several factors including the skill of its pilots, the tactical soundness of its doctrine for deploying its fighters, and the numbers and performance of those fighters. Many modern fighter aircraft also have secondary capabilities such as ground attack and some types, such as fighter-bombers , are designed from
22983-641: The theatre. The M.S.406 had a parallel career in Finland. In February 1940, the first 30 French fighters were allocated to LeLv 28 , commanded by Major Jusu. These aircraft received the Finnish designations MS-301 to MS-330. They were used in combat against the USSR during the Winter War , and carried out 259 operational sorties and shot down 16 Soviet aircraft. In modified form, the M.S.406 were later involved in
23146-481: The third and tenth which served as examples for subcontractors Société nationale des constructions aéronautiques de l'ouest (SNCAO) and Société nationale des constructions aéronautiques du Midi (SNCAM), and the twelfth and thirteenth functioned as prototypes for the Swiss D-3801 and D-3800 export models. Variants of the aircraft, including some which later entered mass production, were first represented amongst
23309-485: The top wing with no better luck. An alternative was to build a "pusher" scout such as the Airco DH.2 , with the propeller mounted behind the pilot. The main drawback was that the high drag of a pusher type's tail structure made it slower than a similar "tractor" aircraft. A better solution for a single seat scout was to mount the machine gun (rifles and pistols having been dispensed with) to fire forwards but outside
23472-464: The two Rotten could split up at any time and attack on their own. The finger-four would be widely adopted as the fundamental tactical formation during World War Two, including by the British and later the Americans. World War II featured fighter combat on a larger scale than any other conflict to date. German Field Marshal Erwin Rommel noted the effect of airpower: "Anyone who has to fight, even with
23635-559: The type continued in France for sometime after the Armistice of 22 June 1940 under German supervision. The M.S.406 was exported to a range of customers. Out of 160 aeroplanes ordered by Poland, none had reached Polish territory before the outbreak of war, with the first consignment sent on 29 August 1939. Of particular note was its service in the hands of Finnish and Swiss air forces; both operators chose to develop indigenous derivatives of
23798-428: The type's performance; in response to the accidents, improvements such as the strengthening of the undercarriage and the cabin hood were implemented during mid-1939. In spite of complaints regarding the forward fuselage exterior covering and motor attachments, no corrective actions were implemented to address these concerns. Production M.S.406s quickly followed the earlier examples. Between December 1938 and January 1939,
23961-542: The very end of the inter-war period in Europe came the Spanish Civil War . This was just the opportunity the German Luftwaffe , Italian Regia Aeronautica , and the Soviet Union's Voenno-Vozdushnye Sily needed to test their latest aircraft. Each party sent numerous aircraft types to support their sides in the conflict. In the dogfights over Spain, the latest Messerschmitt Bf 109 fighters did well, as did
24124-478: The war as the weapons used were lighter and had a higher rate of fire than synchronized weapons. The British Foster mounting and several French mountings were specifically designed for this kind of application, fitted with either the Hotchkiss or Lewis Machine gun , which due to their design were unsuitable for synchronizing. The need to arm a tractor scout with a forward-firing gun whose bullets passed through
24287-443: The war. Fighter development stagnated between the wars, especially in the United States and the United Kingdom, where budgets were small. In France, Italy and Russia, where large budgets continued to allow major development, both monoplanes and all metal structures were common. By the end of the 1920s, however, those countries overspent themselves and were overtaken in the 1930s by those powers that hadn't been spending heavily, namely
24450-526: The wing planform and dihedral , while the Chauvière -built propeller was replaced by a Levasseur -built counterpart. The second M.S.405-2 prototype with a 671.1 kW (900 hp) Hispano-Suiza 12Ycrs engine did not make its first flight until 20 January 1937, almost a year and a half behind the first prototype. The second prototype was able to attain a speed of 443 km/h (275 mph) during testing. During July 1937, both prototypes were flown to
24613-520: Was acquired in 1948, the type remained in service as a trainer and target tug until 1959. The D.3802 was based on the MS.450 , emerging as the MS.540, with a Saurer YS-2 932.1 kW (1,250 hp) engine. The prototype flew in the autumn of 1944, revealing several shortcomings, but it was capable of 630 km/h (391 mph; 340 kn). 12 were produced seeing limited use with Fliegerstaffel 17 and some other units. The last development of this aircraft
24776-466: Was adopted for some fighters such as the Fokker D.VIII and Morane-Saulnier AI in the later part of the First World War. A parasol wing also provides a high mounting point for engines and during the interwar period was popular on flying boats, which need to lift the propellers clear of spray. Examples include the Martin M-130 , Dornier Do 18 and the Consolidated PBY Catalina . Compared to
24939-401: Was fitted to a modified M.S.410 to create the M.S.450 , giving dramatic improvements in performance, especially at altitude. However the engine did not enter production before France fell, and the similarly modified Dewoitine D.520 (the D.523) was considered a better design for the engine anyway. The M.S.406 airframe was also used in a number of other projects. In 1938, Switzerland obtained
25102-527: Was halted. After the end of the war, the total was brought to 41, which served as advanced trainers with TLeLv 14 until September 1948. In 1952 all remaining Finnish Moranes were scrapped. Data from The Morane Saulnier 406 General characteristics Performance Armament Aircraft of comparable role, configuration, and era Fighter aircraft Fighter aircraft (early on also pursuit aircraft ) are military aircraft designed primarily for air-to-air combat . In military conflict,
25265-418: Was impressive, but the last development of this 1935 fighter design had several shortcomings and was not entirely successful. Its development was halted as P-51D Mustangs became available. France sent 30 M.S.406s to Finland, between 4 and 29 February 1940. By 1943 the Finns had received an additional 46 M.S.406s and 11 M.S.410s purchased from the Germans. By this point, the fighters were hopelessly outdated, but
25428-420: Was no longer a handicap and one or two were used, depending on requirements. This in turn required the development of ejection seats so the pilot could escape, and G-suits to counter the much greater forces being applied to the pilot during maneuvers. In the 1950s, radar was fitted to day fighters, since due to ever increasing air-to-air weapon ranges, pilots could no longer see far enough ahead to prepare for
25591-430: Was often done during the war for propaganda purposes, that the M.S.406 was the finest fighter in the world...but it was certainly a pleasant machine to fly with no vices and great maneuverability". In the aftermath of the armistice , only a single Vichy unit, GC. 1/7, was equipped with the M.S.406. According to Botquin, the deployment of the type from this point onwards reflected the fighter's relative obsolescence; it
25754-485: Was originally intended for a fighter role with the U.S. Navy , but it was canceled. This blurring follows the use of fighters from their earliest days for "attack" or "strike" operations against ground targets by means of strafing or dropping small bombs and incendiaries. Versatile multi role fighter-bombers such as the McDonnell Douglas F/A-18 Hornet are a less expensive option than having
25917-508: Was pioneered before World War I by Breguet but would find its biggest proponent in Anthony Fokker, who used chrome-molybdenum steel tubing for the fuselage structure of all his fighter designs, while the innovative German engineer Hugo Junkers developed two all-metal, single-seat fighter monoplane designs with cantilever wings: the strictly experimental Junkers J 2 private-venture aircraft, made with steel, and some forty examples of
26080-669: Was reduced to relatively minor roles, being used mainly for training purposes in mainland France. A handful of Syrian M.S.406 aircraft flew to Egypt, joining up with the Royal Air Force (RAF) and the Free French Air Force , continuing to be operated there until they became unserviceable. Those that remained in Vichy France's control saw action in Syria against encroaching RAF forces, and on Madagascar against
26243-553: Was the 1907 Santos-Dumont Demoiselle , while the Blériot XI flew across the English Channel in 1909. Throughout 1909–1910, Hubert Latham set multiple altitude records in his Antoinette IV monoplane, eventually reaching 1,384 m (4,541 ft). The equivalent German language term is Eindecker , as in the mid-wing Fokker Eindecker fighter of 1915 which for a time dominated the skies in what became known as
26406-455: Was the D.3803, with 1,118.5 kW (1,500 hp) Saurer YS-3 engine, and modified dorsal fuselage (with an all-round visibility canopy). The D.3803 was armed with three HS-404 20 mm (0.787 in) cannon (one in the nose, two in the wings), plus up to 200 kg (441 lb) bombs and rockets. Despite not having a powerful engine, the type reached 680 km/h (423 mph; 367 kn) at 7,000 m (22,966 ft). The performance
26569-481: Was wrecked. A fifth pilot, Sergent Deshons, was wounded in the head by splinters, forcing him to land. Six days later, on 21 May, 17 Morane of the same unit intercepted 50 Dorniers over Compiègne , escorted by as many Bf 109s. Before the Morane could close in to open fire, the Messerschmitts jumped them and shot down four Moranes almost at once. Two more were too badly damaged to be repaired. On their side,
