The Dewoitine D520 is a French fighter, full-metal, half-shell low wing structure from the beginning of WWII manufactured by SNCA. The first flight of the prototype took place in 1938, and from the beginning of 1940, the D520 began to enter the linear units under the designation D.520C1. Initially, the French air force ordered in 1939 only 200 pieces, but its size was increased, until in April 1940 it was already for the delivery of 2,320 machines (military aviation and navy). The serial machine was powered by a Hispano-Suiza 12Y-45 engine with a capacity of 930KM. Despite the implementation of very modern for those times production methods, until May 1940, only 32 aircraft were delivered to line units, although several dozen machines were delivered to them during the course of the fighting. This was because one D.520 required 7,000 man-hours to complete, compared to 4,500 for the Me109E. The first vessel to receive the D.520 was the Groupe de Chasse I / 3. During the 1940 campaign, the plane turned out to be a bit slower than the Me109E, but definitely more maneuverable, and with at least a comparable rate of climb. He was, without a doubt, as formidable a fighter as his Luftwaffe opponent. Units armed with the D520 shot down a total of 114 enemy masses in May and June 1940. The quality of the D520 is evidenced by the fact that it served in the Vichy State aviation until 1942, as well as was used by the Luftwaffe and produced for the needs of the allies of the Third Reich - mainly Bulgaria and Romania. After 1945, the surviving D520 served as training planes in the French Air Force until 1953. Technical data: Maximum speed: 560 km / h, rate of climb: 14.3 m / s, maximum ceiling 10000 m, maximum range: 1250 km, armament: fixed - 1 20mm Hispano-Suiza HS.404 cannon and 4 machine guns MAC 1934 cal. 7.5 mm.The Messerschmitt Bf-109 is a German metal-structure single-engine fighter in a low wing configuration with a classic tail. It turned out to be the basic and most produced Luftwaffe fighter during World War II. The flight of the prototype took place on May 29, 1935, and serial production continued in the years 1936-1945. In total, it is estimated that a total of about 35,000 Messerschmitt Bf-109 fighters of all varieties were produced, many of which ended up in the Czech and Israeli air forces after the war. The roots of the Bf-109 go back to the competition announced in 1933 by the Luftwaffe for a new fighter plane. In competition with the He-112, the Bf-109 project initially lost, but thanks to Willie Messerschmitt's intrigues, the project could continue and eventually he was the winner of the competition, becoming the Luftwaffe's primary fighter. Several main variants of the Bf-109 were developed in the course of production. The first pre-production series was the Bf-109B (Berta) with different versions of the Junkers Jumo 210 (A or Da) engine. They were tested in Spain from 1937 during the Civil War. The next version is the Bf-109C (Caesar). They had a different engine than the B version, and extensive armament consisting of two 20mm and 2 HP 7.92mm cannons. These machines also fought in the skies of Spain. The third version is the Bf-109D (Dora) with the Junkers Jumo 210 Da or Daimler-Benz DB 600 engine. It fought in the September campaign, but at the turn of 1939/1940 it was replaced by the E version. The most famous model was the Bf-109E (Emil) with a Daimler-Benz 601A or N engine. It was the first to use a three-blade, not a two-blade propeller. Bf-109E fought in the French campaign, over England, and in North Africa and on the Eastern Front. The ace who started his career on the Bf-109E was the famous Adolf Galland. The next version is the Bf-109F (Friedrich), which, according to the German pilots, was the most aerodynamically perfect. It sowed the changed shape of the fuselage, wings, cabin fairings, but no new engine was used. It was put into service at the turn of 1940/1941. As part of the development of the design, further Bf-109 specifications were developed, of which the G (Gustav) version was produced in the largest number of copies. The most important change increasing the machine's performance was the installation of a new 12-cylinder Daimler-Benz DB605A engine with 1475HP. The armament of the Bf-109G was a pair of 13mm machine guns located in the fuselage in front of the cockpit fairing, and the MG151 20mm or heavier MK108 30mm cannon. The last mass-produced version was the Bf-109K (Kurfirst), which production started in October 1944. A Daimler-Benz DB 605DB or DC unit was used as the engine. The Bf-109K was the fastest version produced during World War II, reaching up to 730 km / h. Apart from that, two versions were created - H and Z, but they were rather experimental versions and their mass production did not start. Subsequent improvements in propulsion and armament made the Messerschmitt Bf-109 one of the most dangerous fighters of World War II, and at the same time showed the great potential of the slightly angular airframe created by Willi Messerschmitt. Technical data (version Bf-109 G-6): length: 8.95 m, wingspan: 9.92 m, height: 2.6 m, maximum speed: 640 km / h, rate of climb: 17 m / s, maximum range: 850 km, maximum ceiling 12000m, armament: fixed - 2 MG131 13mm machine guns and 1 MG151 20mm cannon, suspended - 250 kg bombs, or 2 Wfr missile launchers.
