145-606: The Messerschmitt Bf 109 is a German World War II fighter aircraft that was, along with the Focke-Wulf Fw 190 , the backbone of the Luftwaffe 's fighter force. The Bf 109 first saw operational service in 1937 during the Spanish Civil War . It was still in service at the end of World War II in 1945. It was one of the most advanced fighters when it first appeared, with an all-metal monocoque construction,
290-659: A Neutrality Pact in April 1941, and Japan adopted the doctrine of Nanshin-ron , promoted by the Navy, which took its focus southward and eventually led to war with the United States and the Western Allies. In Europe, Germany and Italy were becoming more aggressive. In March 1938, Germany annexed Austria , again provoking little response from other European powers. Encouraged, Hitler began pressing German claims on
435-578: A cautious French probe into the Saarland . The Western Allies also began a naval blockade of Germany , which aimed to damage the country's economy and war effort. Germany responded by ordering U-boat warfare against Allied merchant and warships, which would later escalate into the Battle of the Atlantic . On 8 September, German troops reached the suburbs of Warsaw . The Polish counter-offensive to
580-481: A 1,230 kW (1,672 PS; 1,649 hp) DB 601R racing engine, set a new world air speed record for landplanes with piston engines of 610.95 km/h (379.63 mph), winning the title for Germany for the first time. Converted from a Bf 109D, the V13 had been fitted with a special racing DB 601R engine that could deliver 1,230 kW (1,672 PS; 1,649 hp) for short periods. Heinkel , having had

In place of internal wing armament, additional firepower was provided through a pair of 20 mm MG 151/20 cannons installed in conformal gun pods under the wings. The conformal gun pods, exclusive of ammunition, weighed 135 kg (298 lb); and 135 to 145 rounds were provided per gun. The total weight, including ammunition,
870-669: A closed canopy, and retractable landing gear. A liquid-cooled, inverted-V12 aero engine powered it. It was called the Me 109 by Allied aircrew and some German aces, even though this was not the official German designation. The plane was designed by Willy Messerschmitt and Robert Lusser , who worked at Bayerische Flugzeugwerke during the early to mid-1930s. It was conceived as an interceptor . However, later models were developed to fulfill multiple tasks, serving as bomber escort , fighter-bomber , day -, night-, all-weather fighter , ground-attack aircraft , and aerial reconnaissance aircraft. It
1015-566: A cut-off system: if one radiator leaked you could fly on the second or close both down and fly at least five minutes more. The pilot was protected by armour-plate from the back, and the fuel tank was also behind armour. Our planes had fuel tanks in the centre of their wings: that's why our pilot got burnt. What else did I like about the Messer? It was highly automatic and thus easy to fly. It also employed an electrical pitch regulator, which our planes didn't have. Our propeller system, with variable pitch
1160-565: A distinct disadvantage. Because of its smaller, lighter airframe , the Bf 109 was 30 km/h (20 mph) faster than the He 112 in level flight, and superior in climbing and diving. The Commission ultimately ruled in favour of the Bf 109 because of the Messerschmitt test pilot's demonstration of the 109's capabilities during a series of spins, dives, flick rolls and tight turns, throughout which
1305-408: A large extent. From the inception of the design, priority was given to easy access to the powerplant, fuselage weapons and other systems while the aircraft was operating from forward airfields . To this end, the entire engine cowling was made up of large, easily removable panels which were secured by large toggle latches. A large panel under the wing centre section could be removed to gain access to
1450-492: A light fighter, decreasing the aircraft's rate of roll and manoeuvrability. As a result, the He 112 V4 which was used for the trials had new wings, spanning 11.5 m (37 ft 8.75 in) with an area of 21.6 m (232.5 ft). However, the improvements had not been fully tested and the He 112 V4 could not be demonstrated in accordance with the rules laid down by the Acceptance Commission, placing it at
1595-449: A novel, complex retractable main undercarriage which proved to be unreliable. Initially, the Bf 109 was regarded with disfavour by E-Stelle test pilots because of its steep ground angle, which resulted in poor forward visibility when taxiing; the sideways-hinged cockpit canopy, which could not be opened in flight (but could be dropped by the emergency arm). They were also concerned about the high wing loading. The Heinkel He 112 , based on

When the Bf ;109 was designed in 1934, by a team led by Willy Messerschmitt and Robert Lusser , its primary role was that of a high-speed, short-range interceptor. It used the most advanced aerodynamics of the time and embodied advanced structural design which
1885-524: A pretext to initiate the invasion. The first German attack of the war came against the Polish defences at Westerplatte . The United Kingdom responded with an ultimatum for Germany to cease military operations, and on 3 September, after the ultimatum was ignored, Britain and France declared war on Germany. During the Phoney War period, the alliance provided no direct military support to Poland, outside of
2030-781: A pretext to worsen relations. On 29 August, Hitler demanded that a Polish plenipotentiary immediately travel to Berlin to negotiate the handover of Danzig , and to allow a plebiscite in the Polish Corridor in which the German minority would vote on secession. The Poles refused to comply with the German demands, and on the night of 30–31 August in a confrontational meeting with the British ambassador Nevile Henderson , Ribbentrop declared that Germany considered its claims rejected. On 1 September 1939, Germany invaded Poland after having staged several false flag border incidents as
2175-466: A problem with inexperienced pilots, especially during the later stages of the war when pilots received less training before being sent to operational units. At least 10% of all Bf 109s were lost in takeoff and landing accidents, 1,500 of which occurred between 1939 and 1941. The installation of a fixed "tall" tailwheel on some of the late G-10s and −14s and the K-series helped alleviate the problem to
2320-536: A scaled-down Blitz , was the favourite of the Luftwaffe leaders. Compared with the Bf 109, it was also cheaper. Positive aspects of the He ;112 included the wide track and robustness of the undercarriage (this opened outwards from mid wing, as opposed to the 109s which opened from the wing root ), considerably better visibility from the cockpit and a lower wing loading that made for easier landings. In addition,
2465-475: A secret protocol that defined German and Soviet "spheres of influence" (western Poland and Lithuania for Germany; eastern Poland , Finland, Estonia , Latvia and Bessarabia for the Soviet Union), and raised the question of continuing Polish independence. The pact neutralised the possibility of Soviet opposition to a campaign against Poland and assured that Germany would not have to face the prospect of
2610-774: A similar pact and rejected ceding part of its territory to the Soviet Union. The Soviet Union invaded Finland in November 1939, and was subsequently expelled from the League of Nations for this crime of aggression. Despite overwhelming numerical superiority, Soviet military success during the Winter War was modest, and the Finno-Soviet war ended in March 1940 with some Finnish concessions of territory . In June 1940,

The critical altitude of 6,000 metres was to be reached in no more than 17 minutes, and the fighter was to have an operational ceiling of 10,000 m (33,000 ft). Power was to be provided by the new Junkers Jumo 210 engine of about 522 kW (710 PS; 700 hp). It
2900-531: A two-front war, as it had in World War I. Immediately afterwards, Hitler ordered the attack to proceed on 26 August, but upon hearing that the United Kingdom had concluded a formal mutual assistance pact with Poland and that Italy would maintain neutrality, he decided to delay it. In response to British requests for direct negotiations to avoid war, Germany made demands on Poland, which served as
3045-604: The Anglo-German Naval Agreement and the German–Polish declaration of non-aggression . The situation became a crisis in late August as German troops continued to mobilise against the Polish border. On 23 August the Soviet Union signed a non-aggression pact with Germany, after tripartite negotiations for a military alliance between France, the United Kingdom, and Soviet Union had stalled. This pact had

The interwar period saw strife between supporters of the new republic and hardline opponents on both the political right and left. Italy, as an Entente ally, had made some post-war territorial gains; however, Italian nationalists were angered that the promises made by the United Kingdom and France to secure Italian entrance into

Dates for the beginning of the Pacific War include the start of the Second Sino-Japanese War on 7 July 1937, or the earlier Japanese invasion of Manchuria , on 19 September 1931. Others follow the British historian A. J. P. Taylor , who stated that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and

However, it soon became one of the frontrunners in the contest, as the Arado and Focke-Wulf entries, which were intended as "backup" programmes to safeguard against failure of the two favourites, proved to be completely outclassed.

In 1944, the Western Allies invaded German-occupied France at Normandy , while the Soviet Union regained its territorial losses and pushed Germany and its allies westward. At the same time, Japan suffered reversals in mainland Asia, while the Allies crippled

The war in Europe concluded with the liberation of German-occupied territories ; the invasion of Germany by the Western Allies and the Soviet Union, culminating in the fall of Berlin to Soviet troops; Hitler's suicide ; and the German unconditional surrender on 8 May 1945 . Following the refusal of Japan to surrender on the terms of the Potsdam Declaration ,

Both Italy and Ethiopia were member nations, but the League did little when the former clearly violated Article X of the League's Covenant . The United Kingdom and France supported imposing sanctions on Italy for the invasion, but the sanctions were not fully enforced and failed to end the Italian invasion. Italy subsequently dropped its objections to Germany's goal of absorbing Austria . When civil war broke out in Spain, Hitler and Mussolini lent military support to

Hitler believed that the United Kingdom's refusal to end the war was based on the hope that the United States and the Soviet Union would enter the war against Germany sooner or later. On 31 July 1940, Hitler decided that

Soon the United Kingdom and France followed the appeasement policy of British Prime Minister Neville Chamberlain and conceded this territory to Germany in the Munich Agreement , which was made against the wishes of the Czechoslovak government, in exchange for a promise of no further territorial demands. Soon afterwards, Germany and Italy forced Czechoslovakia to cede additional territory to Hungary, and Poland annexed

Although all of Germany's stated demands had been satisfied by the agreement, privately Hitler was furious that British interference had prevented him from seizing all of Czechoslovakia in one operation. In subsequent speeches Hitler attacked British and Jewish "war-mongers" and in January 1939 secretly ordered a major build-up of the German navy to challenge British naval supremacy. In March 1939, Germany invaded

The loss of one-third of Romania's 1939 territory caused a coup against King Carol II, turning Romania into a fascist dictatorship under Marshal Ion Antonescu , with a course set towards the Axis in the hopes of a German guarantee. Meanwhile, German-Soviet political relations and economic co-operation gradually stalled, and both states began preparations for war. In April 1940, Germany invaded Denmark and Norway to protect shipments of iron ore from Sweden , which

Key events leading up to the war included Japan's invasion of Manchuria , the Spanish Civil War , the outbreak of the Second Sino-Japanese War , and Germany's annexations of Austria and the Sudetenland . World War II is generally considered to have begun on 1 September 1939, when Nazi Germany , under Adolf Hitler , invaded Poland , prompting

Considered by many as the high-water mark of Bf 109 development, the F series abandoned the wing cannon and concentrated all armament in the forward fuselage with a pair of synchronized machine guns above and a single 15 or 20 mm Motorkanone -mount cannon behind the engine, the latter firing between the cylinder banks and through
6525-422: The 109F-series onwards, guns were no longer carried inside the wings. Instead, the Bf 109F had a 20 mm gun firing through the propeller shaft. The change was disliked by leading fighter pilots such as Adolf Galland and Walter Oesau , but others such as Werner Mölders considered the single nose-mounted gun to compensate well for the loss of the two wing guns. Galland had his Bf 109F-2 field-modified with

7105-441: The Bf 109 "the skinny one" (худо́й, khudoy ), for its sleek appearance compared, for example, to the more robust Fw 190. The names "Anton", "Berta", "Caesar", "Dora", "Emil", "Friedrich", "Gustav", and "Kurfürst" were derived from the variant's official letter designation (e.g. Bf 109G – "Gustav"), based on the German spelling alphabet of World War II, a practice that was also used for other German aircraft designs. The G-6 variant

The Messerschmitt 109 made its public debut during the 1936 Berlin Olympics when the V1 prototype was flown. As with the earlier Bf 108, the new design was based on Messerschmitt's "lightweight construction" principle, which aimed to minimise the number of separate parts in the aircraft. Examples of this could be found in

Japan aimed to dominate East Asia and the Asia-Pacific , and by 1937 was at war with the Republic of China . In December 1941, Japan attacked American and British territories in Southeast Asia and the Central Pacific , including Pearl Harbor in Hawaii , which resulted in the US and the UK declaring war against Japan, and

However, other senior German officials like Ribbentrop saw an opportunity to create a Euro-Asian bloc against the British Empire by inviting the Soviet Union into the Tripartite Pact. In November 1940, negotiations took place to determine if the Soviet Union would join the pact. The Soviets showed some interest but asked for concessions from Finland, Bulgaria, Turkey, and Japan that Germany considered unacceptable. On 18 December 1940, Hitler issued

Eight days later France signed an armistice with Germany ; it was divided into German and Italian occupation zones , and an unoccupied rump state under the Vichy Regime , which, though officially neutral, was generally aligned with Germany. France kept its fleet, which
10585-660: The United States was assisting China and the Western Allies, and had amended the Neutrality Act to allow "cash and carry" purchases by the Allies. In 1940, following the German capture of Paris, the size of the United States Navy was significantly increased . In September the United States further agreed to a trade of American destroyers for British bases . Still, a large majority of the American public continued to oppose any direct military intervention in
10730-465: The V4 had a single-piece, clear-view, sliding cockpit canopy and a more powerful Jumo 210Da engine with a modified exhaust system. However, the He 112 was also structurally complicated, being 18% heavier than the Bf 109, and it soon became clear that the thick wing, which spanned 12.6 m (41 ft 4 in) with an area of 23.2 m (249.7 ft) on the first prototype (V1), was a disadvantage for
10875-606: The Yellow River ; this manoeuvre bought time for the Chinese to prepare their defences at Wuhan , but the city was taken by October. Japanese military victories did not bring about the collapse of Chinese resistance that Japan had hoped to achieve; instead, the Chinese government relocated inland to Chongqing and continued the war. In the mid-to-late 1930s, Japanese forces in Manchukuo had sporadic border clashes with
11020-424: The addition of MW-50 water injection boost and high-performance superchargers , boosting engine output to 1,800–2,000 PS (1,324–1,471 kW; 1,775–1,973 hp). From early 1944, some G-2s, G-3s, G-4s and G-6s were converted to two-seat trainers, known as G-12s. An instructor's cockpit was added behind the original cockpit and both were covered by an elongated, glazed canopy. The final production version of
11165-449: The additional armament increased the fighter's potency as a bomber destroyer, it had an adverse effect on the handling qualities, reducing its performance in fighter-versus-fighter combat and accentuating the tendency of the fighter to swing pendulum-fashion in flight. Some of the projected 109K-series models, such as the K-6, were designed to carry 30 mm (1.18 in) MK 108 cannons in
11310-539: The airfield located in the southernmost Augsburg neighborhood of Haunstetten , piloted by Hans-Dietrich "Bubi" Knoetzsch. After four months of flight testing, the aircraft was delivered in September to the Luftwaffe's central test centre at the Erprobungsstelle Rechlin to take part in the design competition. In 1935, the first Jumo engines became available, so V2 was completed in October using
11455-409: The cannon to be fitted with the ammunition feed forward of the spar, while the breech block projected rearward through the spar. A 60-round ammunition drum was placed in a space closer to the wing root causing a bulge in the underside. A small hatch was incorporated in the bulge to allow access for changing the drum. The entire weapon could be removed for servicing by removing a leading edge panel. From
11600-517: The capital Nanking in December 1937. After the fall of Nanking, tens or hundreds of thousands of Chinese civilians and disarmed combatants were murdered by the Japanese . In March 1938, Nationalist Chinese forces won their first major victory at Taierzhuang , but then the city of Xuzhou was taken by the Japanese in May. In June 1938, Chinese forces stalled the Japanese advance by flooding
11745-513: The case, as all three competing companies—Arado, Heinkel and BFW—received the development contract for the L.A. 1432/33 requirements at the same time in February 1934. A fourth company, Focke-Wulf, received a copy of the development contract only in September 1934. The powerplant was to be the new Junkers Jumo 210, but the proviso was made that it would be interchangeable with the more powerful, but less developed Daimler-Benz DB 600 powerplant. Each
11890-478: The company. All Messerschmitt aircraft that originated after that date, such as the Me 210 , were to carry the "Me" designation. Despite regulations by the RLM, wartime documents from Messerschmitt AG, RLM and Luftwaffe loss and strength reports continued to use both designations, sometimes even on the same page. All extant airframes bear the official "Bf 109" designation on their identification plates, including
12035-403: The conflict well into 1941. In December 1940, Roosevelt accused Hitler of planning world conquest and ruled out any negotiations as useless, calling for the United States to become an " arsenal of democracy " and promoting Lend-Lease programmes of military and humanitarian aid to support the British war effort; Lend-Lease was later extended to the other Allies, including the Soviet Union after it
12180-526: The creation of a " New Roman Empire ". Adolf Hitler , after an unsuccessful attempt to overthrow the German government in 1923, eventually became the Chancellor of Germany in 1933 when Paul von Hindenburg and the Reichstag appointed him. Following Hindenburg's death in 1934, Hitler proclaimed himself Führer of Germany and abolished democracy, espousing a radical, racially motivated revision of
12325-453: The directive to prepare for an invasion of the Soviet Union. 20x138mmB The 20×138mmB or Long Solothurn cartridge is a type of ammunition used mainly for anti-aircraft and anti-tank weapons during World War II . The designation means the caliber is 20 mm , the length of the cartridge case is 138 mm and B indicates it is a belted case . The loaded cartridge weighs 300 grams (10.7 oz). The 20×138mmB cartridge
12470-757: The dissolution of the Austro-Hungarian, Ottoman, and Russian Empires. To prevent a future world war, the League of Nations was established in 1920 by the Paris Peace Conference . The organisation's primary goals were to prevent armed conflict through collective security, military, and naval disarmament , as well as settling international disputes through peaceful negotiations and arbitration. Despite strong pacifist sentiment after World War I , irredentist and revanchist nationalism had emerged in several European states. These sentiments were especially marked in Germany because of
12615-662: The end of May completed the German conquest of the Balkans. Partisan warfare subsequently broke out against the Axis occupation of Yugoslavia , which continued until the end of the war. In the Middle East in May, Commonwealth forces quashed an uprising in Iraq which had been supported by German aircraft from bases within Vichy-controlled Syria . Between June and July, British-led forces invaded and occupied
12760-511: The end of the war. World War II changed the political alignment and social structure of the world, and it set the foundation of international relations for the rest of the 20th century and into the 21st century. The United Nations was established to foster international cooperation and prevent conflicts, with the victorious great powers—China, France, the Soviet Union, the UK, and the US—becoming
12905-422: The engines available, a fighter would end up being slower than the bombers it was tasked with catching. A fighter was designed primarily for high-speed flight. A smaller wing area was optimal for achieving high speed, but low-speed flight would suffer, as the smaller wing would require more airflow to generate enough lift to maintain flight. To compensate for this, the Bf 109 included advanced high-lift devices on
13050-521: The final K-4 models. The aircraft was often referred to by the folk-designation, 'Me 109', particularly by the Allies. The aircraft was often nicknamed Messer by its operators and opponents alike; the name was not only an abbreviation of the manufacturer but also the German word for "knife". In Finland, the Bf 109 was known as Mersu , although this was originally (and still is) the Finnish nickname for Mercedes-Benz cars. Soviet aviators nicknamed
13195-575: The first step of what its government saw as the country's right to rule Asia , staged the Mukden incident as a pretext to invade Manchuria and establish the puppet state of Manchukuo . China appealed to the League of Nations to stop the Japanese invasion of Manchuria. Japan withdrew from the League of Nations after being condemned for its incursion into Manchuria. The two nations then fought several battles, in Shanghai , Rehe and Hebei , until
13340-864: The former Chinese imperial capital of Peking after instigating the Marco Polo Bridge incident , which culminated in the Japanese campaign to invade all of China. The Soviets quickly signed a non-aggression pact with China to lend materiel support, effectively ending China's prior cooperation with Germany . From September to November, the Japanese attacked Taiyuan , engaged the Kuomintang Army around Xinkou , and fought Communist forces in Pingxingguan . Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai , but after three months of fighting, Shanghai fell. The Japanese continued to push Chinese forces back, capturing
13485-447: The fuselage. It also allowed simplification of the wing structure, since it did not have to bear the loads imposed during takeoff or landing. The one major drawback of this landing gear arrangement was its narrow wheel track , making the aircraft unstable while on the ground. To increase stability, the legs were splayed outward somewhat, creating another problem in that the loads imposed during takeoff and landing were transferred up through
13630-455: The future of air combat. The result of the studies was four broad outlines for future aircraft: Rüstungsflugzeug III was intended to be a short range interceptor, replacing the Arado Ar 64 and Heinkel He 51 biplanes then in service. In late March 1933, the RLM published the tactical requirements for a single-seat fighter in the document L.A. 1432/33. The projected fighter needed to have
13775-446: The head-to-head portion of the competition. The aircraft participating in the trials were the Arado Ar 80 V3, the Focke-Wulf Fw 159 V3, the Heinkel He 112 V4 and the Bf 109 V2. The He 112 arrived first, in early February 1936, followed by the rest of the prototypes by the end of the month. Because most fighter pilots of the Luftwaffe were used to biplanes with open cockpits , low wing loading, light g-forces and easy handling like
13920-525: The invasion of the Ethiopian Empire (also known as Abyssinia ) by the armed forces of the Kingdom of Italy ( Regno d'Italia ), which was launched from Italian Somaliland and Eritrea . The war resulted in the military occupation of Ethiopia and its annexation into the newly created colony of Italian East Africa ( Africa Orientale Italiana , or AOI); in addition it exposed the weakness of
14065-735: The latter enabling the strategic bombing of population centres and delivery of the only two nuclear weapons ever used in war. World War II was the deadliest conflict in history, resulting in 70 to 85 million deaths , more than half being civilians. Millions died in genocides , including the Holocaust of European Jews, as well as from massacres, starvation, and disease. Following the Allied powers' victory, Germany , Austria , Japan , and Korea were occupied, and war crimes tribunals were conducted against German and Japanese leaders . The causes of World War II included unresolved tensions in
14210-465: The legs at an angle. The small rudder of the Bf 109 was relatively ineffective at controlling the strong swing created by the powerful slipstream of the propeller during the early portion of the takeoff roll, and this sideways drift created disproportionate loads on the wheel opposite to the swing. If the forces imposed were large enough, the pivot point broke and the landing gear leg would collapse outward into its bay. Experienced pilots reported that
14355-444: The loads being distributed through the structure via a series of strong-points. By concentrating the loads in the firewall, the structure of the Bf 109 could be made relatively light and uncomplicated. An advantage of this design was that the main landing gear, which retracted through an 85-degree angle, was attached to the fuselage , making it possible to completely remove the wings for servicing without additional equipment to support
14500-420: The lower radiator flap operated as part of the flap system), thereby increasing the effective flap area. When deployed, these devices effectively increased the wings' coefficient of lift. Fighters with liquid-cooled engines were vulnerable to hits in the cooling system. For this reason, on later Bf 109 F, G and K models, the two coolant radiators were equipped with a cut-off system. If one radiator leaked, it
14645-548: The more powerful DB 600. The first redesign came with the E series , including the naval variant, the Bf 109T (T standing for Träger , carrier ). The Bf 109E ( Emil ) introduced structural changes to accommodate the heavier and more powerful 1,100 PS (809 kW; 1,085 hp) Daimler-Benz DB 601 engine, heavier armament and increased fuel capacity. Partly due to its limited 300 kilometres (190 miles) combat radius on internal fuel alone, resulting from its 660 km (410 mi) range limit, later variants of
14790-502: The permanent members of its security council . The Soviet Union and the United States emerged as rival superpowers , setting the stage for the Cold War . In the wake of European devastation, the influence of its great powers waned, triggering the decolonisation of Africa and Asia . Most countries whose industries had been damaged moved towards economic recovery and expansion . World War II began in Europe on 1 September 1939 with
14935-487: The pilot was in complete control of the aircraft. In March, the RLM received news that the British Supermarine Spitfire had been ordered into production. It was felt that a quick decision was needed to get the winning design into production as soon as possible, so on 12 March, the RLM announced the results of the competition in a document entitled Bf 109 Priority Procurement , which ordered
15080-589: The political European map with the defeat of the Central Powers —including Austria-Hungary , Germany , Bulgaria , and the Ottoman Empire —and the 1917 Bolshevik seizure of power in Russia , which led to the founding of the Soviet Union. Meanwhile, the victorious Allies of World War I , such as France, Belgium, Italy, Romania, and Greece, gained territory, and new nation-states were created out of
15225-599: The port of Tobruk . By late March 1941, Bulgaria and Yugoslavia signed the Tripartite Pact ; however, the Yugoslav government was overthrown two days later by pro-British nationalists. Germany and Italy responded with simultaneous invasions of both Yugoslavia and Greece , commencing on 6 April 1941; both nations were forced to surrender within the month. The airborne invasion of the Greek island of Crete at
15370-482: The propeller hub, itself covered by a more streamlined, half-elliptical shaped spinner that better matched the streamlining of the reshaped cowling, abandoning the smaller, conical spinner of the Emil subtype. The F-type also omitted the earlier stabilizer lift strut on either side of the tail. The improved aerodynamics were used by all later variants. Some Bf 109Fs were used late in the Battle of Britain in 1940 but
15515-503: The rear spar. The wing profile was the NACA 2R1 14.2 at the root and NACA 2R1 11.35 at the tip, with a thickness to chord ratio of 14.2% at the root and 11.35% at the tip. Another major difference from competing designs was the higher wing-loading. While the R-IV contract called for a wing-loading of less than 100 kg/m, Messerschmitt felt this was unreasonable. With a low wing-loading and
15660-722: The remainder of Czechoslovakia and subsequently split it into the German Protectorate of Bohemia and Moravia and a pro-German client state , the Slovak Republic . Hitler also delivered an ultimatum to Lithuania on 20 March 1939, forcing the concession of the Klaipėda Region , formerly the German Memelland . Greatly alarmed and with Hitler making further demands on the Free City of Danzig ,
15805-410: The significant territorial, colonial, and financial losses imposed by the Treaty of Versailles . Under the treaty, Germany lost around 13 percent of its home territory and all its overseas possessions , while German annexation of other states was prohibited, reparations were imposed, and limits were placed on the size and capability of the country's armed forces . The German Empire was dissolved in
15950-459: The spar and the leading edge. The tube channeled cooling air around the barrel and breech, exhausting from a slot at the rear of the wing. The installation was so cramped that parts of the MG 17's breech mechanism extended into an opening created in the flap structure. The much longer and heavier MG FF had to be mounted farther along the wing in an outer bay. A large hole was cut through the spar allowing
16095-498: The start or prelude to World War II. The exact date of the war's end also is not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 15 August 1945 ( V-J Day ), rather than with the formal surrender of Japan on 2 September 1945, which officially ended the war in Asia . A peace treaty between Japan and the Allies was signed in 1951. A 1990 treaty regarding Germany's future allowed
16240-593: The strong Maginot Line fortifications on the Franco-German border, Germany directed its attack at the neutral nations of Belgium , the Netherlands , and Luxembourg . The Germans carried out a flanking manoeuvre through the Ardennes region, which was mistakenly perceived by the Allies as an impenetrable natural barrier against armoured vehicles. By successfully implementing new Blitzkrieg tactics,
16385-406: The swing was easy to control, but some of the less-experienced pilots lost fighters on takeoff. Because of the large ground angle caused by the long legs, forward visibility while on the ground was very poor, a problem exacerbated by the sideways-opening canopy. This meant that pilots had to taxi in a sinuous fashion which also imposed stresses on the splayed undercarriage legs. Ground accidents were
16530-518: The two wars became World War II in 1941. Other proposed starting dates for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939. Others view the Spanish Civil War as
16675-415: The use of two large, complex brackets which were fitted to the firewall. These brackets incorporated the lower engine mounts and landing gear pivot point into one unit. A large forging attached to the firewall housed the main spar pick-up points and carried most of the wing loads. Contemporary design practice was usually to have these main load-bearing structures mounted on different parts of the airframe, with
16820-607: The variant came into common use only in the first half of 1941. The G series , or Gustav , was introduced in mid-1942. Its initial variants (G-1 through G-4) differed only in minor details from the Bf 109F, most notably in the more powerful 1,475 PS (1,085 kW; 1,455 hp) DB 605 engine. Odd-numbered variants were built as high-altitude fighters with a pressurized cockpit and GM-1 boost, while even-numbered variants were un-pressurized, air superiority fighters and fighter-bombers. Long-range photo-reconnaissance variants also existed. The later G series (G-5 through G-14)
16965-513: The war were not fulfilled in the peace settlement. From 1922 to 1925, the Fascist movement led by Benito Mussolini seized power in Italy with a nationalist, totalitarian , and class collaborationist agenda that abolished representative democracy, repressed socialist, left-wing, and liberal forces, and pursued an aggressive expansionist foreign policy aimed at making Italy a world power, promising
17110-458: The war years. Another example of the Bf 109's advanced design was the use of a single, I-beam main spar in the wing, positioned more aft than usual (to give enough room for the retracted wheel), thus forming a stiff D-shaped torsion box. Most aircraft of the era used two spars, near the front and rear edges of the wings, but the D-box was much stiffer torsionally , and eliminated the need for
17255-475: The war. Germany annexed western Poland and occupied central Poland ; the Soviet Union annexed eastern Poland ; small shares of Polish territory were transferred to Lithuania and Slovakia . On 6 October, Hitler made a public peace overture to the United Kingdom and France but said that the future of Poland was to be determined exclusively by Germany and the Soviet Union. The proposal was rejected and Hitler ordered an immediate offensive against France, which
17400-512: The west halted the German advance for several days, but it was outflanked and encircled by the Wehrmacht . Remnants of the Polish army broke through to besieged Warsaw . On 17 September 1939, two days after signing a cease-fire with Japan , the Soviet Union invaded Poland under the supposed pretext that the Polish state had ceased to exist. On 27 September, the Warsaw garrison surrendered to
17545-431: The wing to accommodate large ammunition boxes and access hatches, an unusual ammunition feed was devised whereby a continuous belt holding 500 rounds was fed along chutes out to the wing tip, around a roller, and then back along the wing, forward and beneath the gun breech, to the wing root, where it coursed around another roller and back to the weapon. The gun barrel was placed in a long, large-diameter tube located between
17690-443: The wings very thin and light. Two synchronized machine guns were mounted in the cowling, firing over the top of the engine and through the propeller arc. An alternative arrangement was also designed, consisting of a single autocannon firing through a blast tube between the cylinder banks of the engine, known as a Motorkanone mount in German. This was also the choice of armament layout on some contemporary monoplane fighters, such as
17835-481: The wings, including automatically opening leading edge slats , and fairly large camber-changing flaps on the trailing edge . The slats increased the lift of the wing considerably when deployed, greatly improving the horizontal maneuverability of the aircraft, as several Luftwaffe veterans, such as Erwin Leykauf, attest. Messerschmitt also included ailerons that "drooped" when the flaps were lowered (F series and later
17980-483: The wings. Originally the aircraft was designated as Bf 109 by the RLM, since the design was submitted by the Bayerische Flugzeugwerke (literally "Bavarian Aircraft Works", meaning "Bavarian Aircraft Factory"; sometimes abbreviated B.F.W., akin to BMW ) during 1935. The company was renamed Messerschmitt AG after 11 July 1938 when Erhard Milch finally allowed Willy Messerschmitt to acquire
18125-707: The world order , and soon began a massive rearmament campaign . France, seeking to secure its alliance with Italy, allowed Italy a free hand in Ethiopia , which Italy desired as a colonial possession. The situation was aggravated in early 1935 when the Territory of the Saar Basin was legally reunited with Germany, and Hitler repudiated the Treaty of Versailles, accelerated his rearmament programme, and introduced conscription. The United Kingdom, France and Italy formed
18270-614: Was invaded by Germany. The United States started strategic planning to prepare for a full-scale offensive against Germany. At the end of September 1940, the Tripartite Pact formally united Japan, Italy, and Germany as the Axis powers . The Tripartite Pact stipulated that any country—with the exception of the Soviet Union—that attacked any Axis Power would be forced to go to war against all three. The Axis expanded in November 1940 when Hungary , Slovakia , and Romania joined. Romania and Hungary later made major contributions to
18415-465: Was 215 kg. Installation of the under-wing gun pods was a simple task that could be quickly performed by the unit's armourers, and the gun pods imposed a reduction of speed of only 8 km/h (5.0 mph). By comparison, the installed weight of a similar armament of two 20 mm MG 151/20 cannon inside the wings of the Fw ;190A-4/U8 was 130 kg (287 lb), without ammunition. Although
18560-629: Was ahead of its contemporaries. In the early years of the war, the Bf 109 was the only single-engined fighter operated by the Luftwaffe, until the appearance of the Fw 190 . The Bf 109 remained in production from 1937 through 1945 in many different variants and sub-variants. The primary engines used were the Daimler-Benz DB 601 and DB 605 , though the Junkers Jumo 210 powered most of the pre-war variants. The most-produced Bf 109 model
18705-512: Was asked to deliver three prototypes for head-to-head testing in late 1934. Design work on Messerschmitt Project Number P.1034 began in March 1934, just three weeks after the development contract was awarded. The basic mock-up was completed by May, and a more detailed design mock-up was ready by January 1935. The RLM designated the design as type "Bf 109", the next available from a block of numbers assigned to BFW. The first prototype ( Versuchsflugzeug 1 or V1 ), with civilian registration D-IABI ,
18850-469: Was completed by May 1935, but the new German engines were not yet ready. To get the "R III" designs into the air, the RLM acquired four Rolls-Royce Kestrel VI engines by trading Rolls-Royce a Heinkel He 70 Blitz for use as an engine test-bed. Messerschmitt received two of these engines and adapted the engine mounts of V1 to take the V-12 engine upright. V1 made its maiden flight at the end of May 1935 at
18995-404: Was hydraulic, making it impossible to change pitch without engine running. If, God forbid, you turned off the engine at high pitch, it was impossible to turn the propeller and was very hard to start the engine again. Finally, the German ammo counter was also a great thing. Reflecting Messerschmitt's belief in low-weight, low-drag, simple monoplanes, the armament was placed in the fuselage. This kept
19140-477: Was nicknamed by Luftwaffe personnel as Die Beule ("the bump/bulge") because of the cowling's characteristic, bulging covers for the breeches of the 13 mm (.51 in) MG 131 machine guns , with the separate Beule covers eliminated by the time of the G-10 model's introduction of a subtly reshaped upper cowling. In July 1937, not long after the public debut of the new fighter, three Bf 109Bs took part in
19285-479: Was overweight and underpowered, and the design was abandoned after three prototypes had been built. The parasol winged Fw 159, potentially inspired by the same firm's earlier Focke-Wulf Fw 56 , was always considered by the E-Stelle Travemünde facility's staff to be a compromise between a biplane and an aerodynamically more efficient, low-wing monoplane. Although it had some advanced features, it used
19430-453: Was possible to fly on the second or to fly for at least five minutes with both closed. In 1943, Oberfeldwebel Edmund Roßmann got lost and landed behind Soviet lines. He agreed to show the Soviets how to service the plane. Soviet machine gun technician Viktor M. Sinaisky recalled: The Messer was a very well designed plane. First, it had an engine of an inverted type, so it could not be knocked out from below. It also had two water radiators with
19575-456: Was postponed until the spring of 1940 due to bad weather. After the outbreak of war in Poland, Stalin threatened Estonia , Latvia , and Lithuania with military invasion, forcing the three Baltic countries to sign pacts allowing the creation of Soviet military bases in these countries; in October 1939, significant Soviet military contingents were moved there. Finland refused to sign
19720-500: Was produced in a multitude of variants, with uprated armament and provision for kits of packaged, generally factory-installed parts known as Umrüst-Bausätze ("conversion kits", usually contracted to Umbau ) and adding a "/U" suffix to the aircraft designation when installed. Field kits known as Rüstsätze were also available for the G-series but those did not change the aircraft title. By early 1944, tactical requirements resulted in
19865-772: Was repulsed with heavy Italian casualties; the campaign ended within months with minor territorial changes. To assist Italy and prevent Britain from gaining a foothold, Germany prepared to invade the Balkans, which would threaten Romanian oil fields and strike against British dominance of the Mediterranean. In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa . The offensives were successful; by early February 1941, Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken prisoner. The Italian Navy also suffered significant defeats, with
20010-610: Was required to go through the bureaucracy of the League of Nations, which rendered it essentially toothless. The United States, concerned with events in Europe and Asia, passed the Neutrality Act in August of the same year. Hitler defied the Versailles and Locarno Treaties by remilitarising the Rhineland in March 1936, encountering little opposition due to the policy of appeasement . In October 1936, Germany and Italy formed
20155-479: Was secured by two quick-release screw fittings on the firewall. All of the main pipe connections were colour-coded and grouped in one place, where possible, and electrical equipment plugged into junction boxes mounted on the firewall. The entire powerplant could be removed or replaced as a unit in a matter of minutes, a potential step to the eventual adoption of the unitized-powerplant Kraftei engine mounting concept used by many German combat aircraft designs, later in
20300-758: Was superior to many Allied adversaries including the P-51D Mustang, Spitfire Mk. XIV and Hawker Tempest Mk. V. After the war, the 109 was built in Czechoslovakia , as the Avia S-99 and Avia S-199 (with twenty-five S-199s serving with Israel in 1948) and in Spain as the Hispano Aviación Ha 1109 and Ha 1112 . World War II Asia-Pacific Mediterranean and Middle East Other campaigns Coups World War II or
20445-560: Was supplied to several states during World War II and served with several countries for many years after the war. The Bf 109 is the most produced fighter aircraft in history, with a total of 34,248 airframes produced from 1936 to April 1945. Some of the Bf 109 production took place in Nazi concentration camps through slave labor . The Bf 109 was flown by the three top-scoring fighter aces of all time, who claimed 928 victories among them while flying with Jagdgeschwader 52 , mainly on
20590-457: Was that the only place available to mount additional guns was in the wings. Only one spot was available in each wing, between the wheel well and slats, with room for only one gun, either a 7.92 mm MG 17 machine gun , a 20 mm MG FF or a 20 mm MG FF/M cannon. The first version of the Bf 109 to have wing guns was the C-1, which had one MG 17 in each wing. To avoid redesigning
20735-462: Was the Bf 109G series (more than a third of all 109s built were the G-6 series, 12,000 units being manufactured from March 1943 until the end of the war). The initial production models of the A, B, C and D series were powered by the relatively low-powered, 670–700 PS (493–515 kW; 661–690 hp) Junkers Jumo 210 series engines. A few prototypes of these early aircraft were converted to use
20880-452: Was to be armed with either a single 20 mm MG C/30 engine-mounted cannon firing through the propeller hub as a Motorkanone , or two synchronized , engine cowl-mounted 7.92 mm (.312 in) MG 17 machine guns , or one lightweight engine-mounted 20 mm MG FF cannon with two 7.92 mm MG 17s. The MG C/30 was an airborne adaption of the 2 cm FlaK 30 anti-aircraft gun, which fired very powerful "Long Solothurn" ammunition, but
